Anti Asthmatic Activity

Early reports indicated that acute inhalation increased airway patency in healthy individuals (Tashkin et al., 1973 Vachon et al., 1973 Shapiro and Tashkin, 1976) and improved specific airway conductance in asthmatics (Tashkin et al., 1974, 1975b Vachon et al., 1976). However, there is good evidence that chronic smoking of cannabis restricts the airways and that, as with tobacco, unspecified irritants in the smoke can cause bronchospasm (Henderson et al., 1972). Aerosolised preparations of THC have produced bronchodilation in both healthy individuals and asthmatics (Tashkin et al., 1974, 1975a Abboud and Sanders, 1976 Williams et al., 1976) but in asthmatic subjects, bronchoconstriction has also been observed. For example, Abboud and Sanders (1976) administered aerosolised THC to six asthmatic patients, three of whom showed increases in specific airway conductance indicating bronchodilation the remaining three subjects showed a decrease in conductance and the overall mean, excluding...

Asthma exacerbation most likely diagnosis

Most people with acute asthma present with a constellation of symptoms consisting of cough, dyspnea, and wheezing. These typically occur simultaneously. Acute attacks are set of by some type of stimulant, and the patient has been exposed to some type of stimulant, which has produced an allergic response. An asthma exacerbation may or may not be accompanied by fever, depending on the initiating trigger. This patient is most likely having an acute asthma exacerbation, given her symptoms of shortness of breath, acute allergic symptoms, and the findings of wheezing on physical examination. Barnes Asthma and COPD Basic Mechanisms and Clinical Management, 1s Edition Chapter 65 - Acute Exacerbations of Asthma, Chakradhar Kotaru, 2002, Elsevier Science, pp. 669-692 When alveoli are filled with purulent material, as in pneumonia, there is consolidation in the alveoli causing dullness to percussion. Breath sounds in that area may be bronchial, or harsh, or even absent. Tactile fremitis is...

Diagnosis of exerciseinduced asthma and EIB

Exercise-induced asthma (EIA) is a condition with EIA symptoms, whereas EIB can be understood as the demonstration of EIB by lung function measurements after an exercise test or spontaneous exercise. EIA and EIB can be diagnosed in several ways. The optimal way is to employ a standardised exercise test and measure lung function before and after exercise. Standardisation is particularly important in the follow-up of EIA over time, when comparing different individuals and in epidemiological studies. Previously, EIB diagnosed by exercise testing was reported to be found in 70-80 of asthmatic patients 9 . However, presently this has changed dramatically with the widespread use of anti-inflammatory treatment of asthma with inhaled steroids. EIB is rapidly and markedly influenced by inhaled steroids 14-16 , and this puts increased demands upon the standardisation of exercise test with respect to work-rate (WR) and environmental factors. ambient temperature of 20-25 C, while running on a...

Summary Chlamydia pneumoniae As An Asthma Inducer

A growing body of evidence (based on culture isolation, polymerase chain reaction (PCR) detection, serologic studies, and treatment results) links Cpn infection with asthma primarily in adults.(53,59,135) and in children as well.(54,56) Nonatopic asthma has been associated with an infectious initiation in general(27) and with Cpn infection in particular.(8,117,128) Cpn respiratory tract infections can initiate asthma(8) and are present in up to one-half of adults with asthma.(116) It is even possible that the contribution of Cpn infection to asthma is so great

Antiasthmatic Drugs

Antiasthmatic drugs, such as theophylline and theobromine, are used for treatment of neonatal breathing disorders or of respiratory conditions that affect adults or children, such as asthma. Theophylline's action is in bronchodilation and smooth muscle relaxation. Bronchodilation is the term for respiratory airway opening. Anti-asthmatic drugs are usually given intravenously for initial therapy, followed by a regimen of oral dosages. Toxicity causes nausea, vomiting, diarrhea, headache, cardiac rhythm problems, and seizures. Theophylline is commonly measured with immunoassay, while theobromine is generally measured by high-pressure liquid chromatography (HPLC).


Asthma is a common condition a careful history and objective recording of simple severity markers, such as pulse and respiratory rate, blood pressure, speech, chest auscultation, mental state, and peak expiratory flow rate, should identify patients who require hospitalization or urgent treatment (Table 4) (12). Detainees with asthma should be allowed to retain bronchodilators for the acute relief of bronchospasm (e.g., salbutamol or the equivalent), with instructions left with the custody sergeant on other treatment if required.

Types Of Asthma

Asthma associated with specific allergic reactions avoidance is particularly relevant to managing this type of asthma. Asthma not associated with known allergy Some patients exhibit wheeze and breathlessness in the absence of an obvious allergen or atopy. They are considered to have intrinsic asthma and because of a lack of an identifiable allergen, allergen avoidance has no place in their management. Exercise-induced asthma Asthma associated with chronic obstructive pulmonary disease A number of patients who have persistent airflow obstruction exhibit considerable variation in airways resistance and hence in their benefit from bronchodilators drugs for asthma. It is important to recognise the coexistence of asthma with chronic obstructive pulmonary disease in some patients, and to assess their responses to bronchodilators or glucocorticoids over a period of time (as formal tests of respiratory function may not reliably predict clinical response in this setting).

Anti Asthmatic

Theophylline, a drug used in the treatment of asthma, has a narrow therapeutic window. Because of this narrow window, it is important to know the serum concentration in order to determine whether it is in the therapeutic or toxic range. Additionally, theophylline and the closely related compound, caffeine, are frequently used to treat apnea in newborns. Like the antiepileptic drugs, these compounds have been analyzed by either MEKC or CZE. MEKC allows direct injection of serum, urine, or saliva in a borate buffer, pH 9.0, in the presence of SDS with separation in about 15 min (73). We obtained a good correlation (r 0.98) to immunoassay when theophylline was measured by CZE in borate buffer, pH 8.5 (15). Zhao et al. (74) determined caffeine and its metabolites by MEKC, and Johansson et al. (75) used CZE to measure theophylline in phosphate-borate buffers. Caffeine, dyphylline, theobromine, and theophylline have also been separated by MEKC in borate buffer, pH 9.3 containing SDS and 30...


Jusko studied the effects of cannabis on the clearance of theophylline in two studies. In the first of these, fourteen cannabis smokers were recruited (Jusko et al., 1978). Cannabis users had smoked the drug at least twice weekly for several months. Seven of them smoked cannabis only, and seven smoked tobacco regularly as well. The half-life and clearance of aminophylline varied in each of the groups studied In the second study, the clearance of theophylline was compared in three different groups (Jusko et al., 1979). One hundred and seventy-seven patients that did not smoke cannabis had a clearance of 56 ml hr kg. Nine participants who smoked cannabis less than once a week had similar clearance values to non-users (54 ml hr kg). However, those who smoked cannabis at least twice per week had markedly elevated clearance of theophylline (83 ml hr kg). Smoking cannabis accelerates the elimination of theophylline, unless usage is very low. Jusko suggests that the method of administration...

Siliquariaspongia japonica.239 Two chemotypes of marine bryozoan Bugula neritina were identified.240 A new polysaccharide exhibiting anti-HIV activity and made up of galactan sulfate was isolated from the marine clam Meretrix petechialis241 Dolastatin 15, a potent antineoplastic peptide from the mollusk Dolabella auriculata was undergoing clinical trials in Europe and North America.242 Two sesquiterpenes active against phytopathogenic fungus Cladosporium cucumerinum were isolated from a marine soft coral of the genus Heteroxenia243 A stereocontrolled synthesis of the antitumor agent (-)-laulimalide was achieved.244 Linckosides A and B, the new neuritogenic steroid glycosides were isolated from the Okinawan starfish Linckia laevigata.245 Three alkaloids having an unusual decahydroquinoline skeleton and showing significant and selective antiplasmodial and antitrypanosomal activities, were obtained from a new tunicate species of the genus Didemnum.246 These bioactive alkaloids may serve...

Muscle cardiovascular and respiratory abnormalities

Hyperventilation or over-breathing is yet another posited cause for CFS. Based on patients' perceptions of their feelings of shortness of breath following voluntary hyperventilation, Rosen and colleagues (Rosen et al. 1990) concluded that CFS was nothing more than chronic hyperventilation. Subsequent studies using more rigorous methods to measure hyperventilation, such as measuring decreased levels of carbon dioxide in the system, have shown that carbon dioxide levels cannot account for either the degree of symptoms nor functional impairment reported by CFS patients (Lavietes et al. 1996 Saisch et al. 1994). CFS patients with and without hyperventilation report the same severity of fatigue-related symptoms (Bazelmans et al. 1997). Saisch et al. (1994) also found that CFS patients with unequivocal hyperventilation had either panic disorder or asthma which would account for the decreased levels of carbon dioxide in their system. Consequently, while hyperventilation may contribute to the...

Tissue Kallikrein and Hyaluronan Interaction and Enzyme Inhibition

Tissue kallikrein (TK) is a serine protease that generates lysyl-bradykinin in the airways by cleaving kininogens. Bradykinin is an important mediator of airway inflammation and has been implicated in the pathophysiology of asthma (29,30). Tissue kallikrein is made in submucosal gland cells and secreted into the airway, albeit with inhibited enzymatic activity. The inhibition of TK activity in the airway was a puzzle as it is relatively insensitive, at least in vitro, to known serine protease inhibitors found in the bronchial lumen (31). As TK activity should be suppressed in the airway lumen under normal conditions, it was concluded that enzyme activity was likely regulated by substrate availability. We have now shown, however, that hyaluronan inhibits bronchial TK activity by binding to it (32). Therefore, hyaluronan functions as a natural inhibitor for bronchial TK in the airway lumen. This finding was novel for bronchial TK in the airways, but hyaluronan and other...

Comparison of selfpaced and externally paced shuttle walking tests

Although the self- and externally paced SWTs are fundamentally different, attempts have been made to compare the two protocols. The original study describing the SWT included a comparison with the 6MWT 6 . The authors found that the distance completed in both tests was similar for the majority of patients, but that the pattern of response was different. More recently, Eiser et al. 73 compared the reliability, reproducibility and sensitivity to change of the 6MWT, 2MWT and ISWT in 57 moderate-to-severe COPD patients. The mean baseline distance for the 6MWT was significantly greater than that for the ISWT (424 versus 270 m, respectively). All three tests demonstrated satisfactory reproducibility and reliability, and established reprodu-cibility over successive days and a 2-week period. After nebulised bronchodilator administration, a significant change was detected for all three tests, although the 6MWT distance was below the previously defined threshold. The authors suggested that the...

Trastuzumab Herceptin Trastuzu

Herceptin Chemical Structure

Adverse events from Trastuzumab administration are rare but can result in severe hy-persensitivity, including systemic anaphy-laxis, urticaria, bronchospasm, angioedema, or hypotension. A recent warning of cardiotox-icity has been issued for Trastuzumab, where its use in patients with cardiac dysfunction has resulted in congestive heart failure. This phenomenon is currently under further evaluation and investigation.

Pulmonary vasodilator drugs

The situation has been radically changed by the recent discovery of the role of nitric oxide as a physiological vasodilator.77 Nitric oxide is also a bronchodilator.78 It has now been shown that nitric oxide can vasodilate the pulmonary vascular bed when inhaled in concentrations of 10-80 p.p.m. (parts per million). The advantage of the inhalational route of administration is that the nitric oxide only dilates the pulmonary vessels supplying ventilated alveoli, and does not reach non-ventilated alveoli where vessels are constricted by hypoxia. Furthermore, it has no effect on systemic vessels because it is immediately deactivated by combination with haemoglobin.79 The inhalation of 18 p.p.m. of nitric oxide decreases pulmonary artery pressure and shunt in patients with ARDS, and the therapy has been continued for many days without apparent toxicity.80 An even more recent study has demonstrated a significant improvement in oxygenation without any reduction in pulmonary artery pressure...

Hyaluronan Size and Airway Pathophysiology

In the many airway pathologies, ROS and RNS production is increased and could therefore lead to hyaluronan degradation. Allergen challenge, for instance, causes bronchoconstriction, at least in part, via oxidative stress (62). We, therefore, examined the effects of segmental allergen challenge on the average airway hyaluronan size recovered in BAL from six human volunteers with allergic asthma in comparison with six healthy subjects (samples were kindly provided by Drs Hastie A and Peters S, Thomas Jefferson University, Philadelphia, PA). If our hypothesis that hyaluronan is degraded by oxidative stress applies as in other tissues, the size of recovered hyaluronan should decrease but the amount of soluble hyaluronan should increase due to ROS-mediated cleavage and at least partial release from the cell surface. Figure 1 Changes in hyaluronan size after allergen challenge BAL from asthmatic patients was collected before (a) and 24 h after (b) segmental allergen challenge. The lavages...

Characterization of Th1 and Th2 cells

CD4+ T-lymphocytes are heterogeneous in terms of production of cytokines, and have different functions 19, 20 . Th1 cells secrete IL-2, IFN-y and lym-photoxin which explains their role in activating macrophages and cytotoxic cells and therefore in cell-mediated immune responses. Th1 cells also help B-cells in the production of some isotypes IgG2a in mice and IgG2b in rats. Th2 cells produce IL-4, IL-5, IL-6, IL-10 and IL-13, promote IgE and IgG1 switch (in rats and mice), and activate eosinophils and mast cells. Although there is no marker that allows to identify Th1 and Th2 cells, these subsets express different chemo-kine receptors 21 and display specific transcription factors c-maf, NIP-45 and GATA-3 characterize Th2 cells and control IL-4 and IL-5 gene transcription while T-bet is expressed by Th1 cells and is essential for IFN-Y expression (reviewed in 22 ). The Th1 Th2 cell dichotomy brought new insights in the pathogenic mechanisms responsible for immunopathological...

Wheezing Through Lungs Very Poor Air Intake Pale Cool And Clammy And Low Blood Pressure

Sensitization for Type I immediate hypersensitivity reactions occurs when antigen exposure leads to the production of IgE and subsequent binding to FceR on mast cells and basophils. The effector phase of Type I hypersensitivity reactions is caused by inflammatory mediators, (histamine, prostaglandins, leukotrienes, and platelet activating factor) released from mast cells and basophils following antigen binding to cell bound IgE. Skin testing identifies antigens causing immediate hypersensitivity reactions. Patients with severe reactions may be at risk when tested in this manner, and for these, an antigen specific radioallergosorbent (RAST) test is more appropriate. Clinical manifestations of immediate hypersensitivity reactions include allergic rhinitis, asthma, and anaphylaxis. Treatments include (i) minimizing the exposure to the antigens that trigger the reaction, (ii) pharmacological intervention, and (iii) desensitization.

Introduction Analysis Of Urinary Drugs In Clinical And Forensic Toxicology

Clinical and forensic toxicology is concerned with the detection, identification, and measurement of toxic compounds and their metabolites in human body fluids and tissues. Most often the toxic compounds are drugs taken either accidentally or intentionally in quantities sufficient to cause an adverse reaction or death. Analysis and identification of a possible drug or drug combinations, toxicological drug screening and confirmation should encompass as many different classes of drugs as possible. The most important classes being salicylate, paracetamol, antiepileptics, antidepressants, neuroleptics, hypnotics (benzodiazepines, barbiturates, diphenhydramine), digoxin, and theophylline, as well as many illicit drugs, such as opiates, methadone, D-lysergic acid diethylamide (LSD), cocaine, and or its major metabolite benzoylecgonine, cannabinoids and amphetamines. Currently, urinary drug monitoring has established itself as the basis of clinical and forensic toxicology. It is also the...

Fluid balance in the lung

Thoracic Extra Anatomic Air

Increased capillary hydrostatic pressure may result from overtransfusion, an obstruction to pulmonary venous outflow (for example, caused by left atrial myxoma) or to left heart failure resulting from mitral valve disease or severe dysrhythmias. It may occur when blood flow to a restricted vascular bed is suddenly increased by correction of an anatomical defect (for example, repair of Fallot's tetralogy), and may also be induced by extreme exercise, particularly if the vascular bed is already constricted by hypoxia (as in high altitude pulmonary oedema). High pressure oedema fluid has a low protein content. Extremely high pulmonary capillary pressures (in the region of 30-50 mm Hg) may create what has been termed stress failure of the pulmonary vasculature.92 Discontinuities appear in the bodies of endothelial and type I epithelial cells, whereas the basement membrane often remains intact, and these lesions permit leakage of fluid and protein into the alveoli. Similar abnormalities...

Exercise testing in the prognostic evaluation of patients with lung and heart diseases

Awhonn Staffing Guidelines Pdf

In COPD patients, several resting variables indices have been proven to predict mortality. The best known is the forced expiratory volume in one second (FEVl) 6 . More recently, other indices have been studied body mass index (BMI) 7, 8 inspiratory capacity total lung capacity ratio 9 arterial hypoxaemia during sleep 10 pulmonary arterial pressure 11 mixed venous oxygen pressure 12 and degree of breathlessness 13 . Since the mid 1990s, however, given the systemic nature of the disease, more and more attention has been paid to skeletal muscle dysfunction 14-16 and, therefore, to the prognostic value of correlates of exercise intolerance. Among CPET variables, Vo2,peak has been reported, in a large prospective series (n 150), to better predict mortality at 5 yrs than post-bronchodilator FEV1 (fig. 1) 17 .

Narrowing of the pulmonary vessels

Pulmonary blood vessels may also be narrowed by a decrease in transmural pressure caused by a reduction in lung volume or an increase in interstitial pressure resulting from pulmonary oedema. A more common cause of narrowing is an increase in alveolar pressure as a result of an increase in airway resistance. This appears to be an important cause of pulmonary hypertension in patients with asthma and chronic bronchitis.

Treating Hypertension

Depending on the patient's age (see above) use either a p Blocker or thiazide Diuretic as firstline therapy, unless there is a compelling reason to avoid these (e.g. asthma and gout, respectively). If the first drug is effective but not tolerated, switch to the other member of the pair i.e. ACE inhibitor (or AIIRA) instead of P-blocker, Calcium blocker instead of diuretic.

Persistent Infection And Aberrant Forms

Chlamydia Pneumoniae Diagnosis

C. pneumoniae is regarded as a common cause of respiratory tract infections and it can cause prolonged or chronic infections which may be due to persistence for months or years.(14,30) These persistent infections have been implicated in the development of a number of chronic diseases including atherosclerosis, asthma, and obstructive pulmonary diseases (see other chapter) . These persistent chlamydial infections can be established in vitro using several methods involving cytokines,(31-34) antibiotics,(35,36) and deprivation of certain nutrients.(37) Despite differences in treatment, chlamydiae respond to form inclusions containing atypical RBs, which occasionally have been shown to be pleomorphic forms, termed aberrant bodies (ABs). The ABs are generally larger in diameter than typical RBs, and display a sparse densinometric appearance (Fig. 12). No evidence of redifferentiation into EBs has been documented. However, when the growth inhibitory factors are removed, the ABs can be...

Clinical Effects Of Sulfur Mustard

Laboratory animal studies have shown that mustard is mutagenic and carcinogenic, and thus, it is not surprising that it is carcinogenic in man.7-9 Both Morgenstern et al. and Buscher and Green emphasize that chronic low-dose exposure over months to years in occupationally exposed workers leads to chronic bronchitis, bronchial asthma, hoarseness, aphonia, and hypersensitivity to smoke, dust, and fumes.10,11 Such individuals typically show persistent disability, with increased susceptibility to respiratory tract infections and evidence of bronchitis and bronchiectasis.10-12 Inhalation of mustard vapor primarily affects the laryngeal and tracheobronchial mucosa.12 Evidence exists to suggest that mustard inhalation causes sustained respiratory difficulties even after the acute lesions have healed. Clinical follow-ups on 200 Iranian soldiers who were severely injured by mustard during the Iran-Iraq War indicate that about one third had experienced persistent respiratory effects 2 years or...

Differential diagnosis of EIB

There are several important differential diagnoses relating to EIA or EIB in children and adolescents, and particularly in adolescents who participate in sports. One frequent differential diagnosis is exercise-induced inspiratory stridor or exercise-induced vocal cord dysfunction 28 . The symptoms are inspiratory stridor occurring during maximum exercise, which ceases when exercise is terminated unless hyperventilation is maintained. During exercise testing, audible inspiratory sounds can be heard arising from the laryngeal area, which is not alleviated by bronchodilators or other asthma medication. The condition most often occurs in young well-trained athletic females aged 15-16 yrs. Symptoms only occur during maximum exercise. One possible differential diagnosis of this syndrome is paradoxical movement of the vocal cords with adduction during inspiration. This may also occur without exercise. The diagnoses are made by direct fibreoptic laryngoscopy during exercise.

Sports Preparticipation Examination

Accounting for about one-third and anomalous coronary arteries for about one-fifth of cardiac anomalies. The history is the most important tool in screening for these abnormalities. All adolescents and their parents should be asked about personal history of exertional chest pain, dyspnea, syncope, history of heart murmurs, and family history of hypertrophic cardiomyopathy other congenital cardiac abnormalities or premature cardiac deaths. Other important historical information includes history of asthma or other pulmonary disorders, orthopedic injuries, heat-related illness, and absence of one of a paired organ (e.g single kidney, testicle, ovary, etc).

Clinical Approach

Diagnose Coughing Algorythm

Evaluation of chronic cough begins with a detailed history and physical examination, including smoking habits, complete medication list, environmental and occupational exposures, and any history of asthma or obstructive lung disease. Specific questions regarding the precipitating factors, duration, character, and development of the cough should be elicited. Although the physical examination or nature of the cough rarely identifies the cause, meticulous review of the ears, nose, throat, and lungs may suggest a particular diagnosis. For example, a cobblestone appearance of the oropharynx (representing lymphoid hyperplasia) or boggy erythematous nasal mucosa can be consistent with postnasal drip. End-expiratory wheezing suggests active bronchospasm. whereas localized wheezing may be consistent with a foreign body or a bronchogenic tumor. In more than 90 of cases, a negative chest radiograph in an immunocompetent nonsmoker guides the physician to one of three diagnoses postnasal drip,...

Conclusion Chlamydia pneumoniae Chronic Nonspecific Lung Disease Cnsld And The Dutch Hypothesis

Bronchitis, asthma, emphysema and irreversible or persistent obstructive lung disease. In 1961 Orie(23) proposed the Dutch Hypothesis which stated that CNSLD represented different expressions of a single disease entity characterized by an hereditary predisposition to develop allergy and bronchial hyper reactivity in response to environmental factors. Prior to the discovery of the Cpn-asthma association, the pros and cons of the Dutch Hypothesis were fully debated without the hypothesis being proven or disproven.(9,10) It should be obvious to the reader of this review that the discovery of Cpn as a potential factor in asthma and COPD casts new light on the importance of examining the concept of CNSLD as a pathophysiologic entity. It is now well established that acute Cpn infection can cause acute bronchitis and pneumonia(149,150) and additional evidence presented herein suggests that lower respiratory tract illnesses caused by acute Cpn infection can develop into asthma and chronic...

Effects of Current Therapy of Chronic Viral Hepatitis on Drug Metabolism

Idiosyncratic Response Drugs Cartoon

There have been a number of reported examples of IFN-drug interactions. Treatment with IFN-a was reported to potentiate the anticoagulant effects of warfarin (coumadin) in a woman with CHC (28). Also, influenza vaccination, which is known to increase endogenous production of IFNs, was reported to increase the anticoagulant effect of warfarin (29). IFN-a slows the clearance of some highly metabolized drugs, such as theophylline (30) for example, the clearance of theophylline was reduced by 33 in cancer patients treated with IFN-a (31).

Do We Need An Antic pneumoniae Vaccine

Whether there are sufficient benefits tojustify children's vaccination seems at present unlikely, since chlamydial respiratory tract infection in children is generally mild. However, transmission of infection to siblings or parents, and the consequences of infection in asthmatic pediatric patients may here be significant parameters to consider.(4) The prevention of arteriosclerosis by blocking C. pneumoniae infection is unlikely to provide a justification for a vaccine for children, until a truly causal role of C. pneumoniae in the development of atherosclerosis has been shown to exist. If C. pneumoniae is proven to be a cause of atherosclerosis, a therapeutic and effective vaccine would be of immense value. In fact, the development and use of an effective C. pneumoniae vaccine might provide the best experiment to investigate the role of C. pneumoniae in cardiovascular disease. An improved understanding of the biology of C. pneumoniae in adults is also necessary to justify a vaccine...

Side Effects Toxicity and Contraindications of the Macrolide Antibiotics

Mild Ischemic Colitis

Thus, macrolides may have an impact on the drug level of other drugs using these enzymes for drug metabolism. For example, combined therapy with a macrolide and theophylline (a bronchodilator) or car-bamazepine (a psychotropic drug) causes an increase in the serum levels of the latter drugs. Cardiac arrhythmias such as ventricular tachycardia have been reported in patients receivingerythromycin A therapy. Thus, mac-rolides are contraindicated in patients receiving terfenadine therapy who have preexisting cardiac abnormalities (arrhythmia, bradycar-dia, QT interval prolongation, ischemic heart disease and congestive heart failure). Hepato-toxicity (132), ototoxicity (133), dermatologie effects (134), pancreatitis (135), cardiovascular toxicity such as QT prolongation (136) and induced hypotension (137), and hemolytic

Recreational Drugs and the Nervous System

Used legally to treat obesity, asthma, and narcolepsy. Herbal products containing ephedra, a drug originally procured from the Mah huang plant and also synthesized in laboratories, have been marketed as treatments for weight loss and for performance enhancement. Methamphetamine is an illegal amphetamine. A crystalline form of methamphetamine called ice is smoked to produce effects similar to crack cocaine.

Epigenetic Basis Of Disease

HATs have also been implicated in cardiac hypertrophy, which is characterized by an increased HAT activity (Gusterson et al., 2002). Consistent with this observation, p300 knockout mice show reduced expression of muscle proteins and cardiac structural defects (Yao et al., 1998). Apart from the acetylation of histone tails, p300 serves as a transcriptional coactivator for hypertrophy responsive transcriptional factors such as GATA-4, SRF and MEF2. Besides, cardiac hypertrophy, several airway diseases such as asthma and chronic obstructive pulmonary disease (COPD), have an indirect dependence on HATs through the pro-inflammatory transcription factor, NF-kB. NF-kB is known to associate with different HATs such as CBP p300, PCAF, GRIP-1 and SRC1. drugs using small molecular modulators of HATs was garcinol, a polyisoprenylated benzophenone derivative from Garcinia indica fruit rind. Garcinol was a potent inhibitor of p300 both in vitro and in vivo and a potent inducer of apoptosis in HeLa...

Multiple Chioce On Breast Cancer

A 31-year-old nurse presents to your office complaining about a painful lump in her right breast next to the nipple. She states it has been there for several months and won't go away. She recently started taking birth control pills after remarrying. Her past medical history is significant for asthma and two spontaneous vaginal deliveries. Family history reveals no breast or ovarian disorders. She denies any tobacco or drug use and drinks alcohol socially. On exam, you feel a 1-cm lump medial to her areola. It is round soft and very tender. There are no skin retractions and no palpable lymph nodes in the axilla. Her left breast also has a 4-cm soft lump medial to the areola that is not quite as tender. The patient states she hadn't noticed that area before. What type of breast mass is the most likely cause of her pain

Respiratory Disorders

As a result of chronic obstructive pulmonary disease (COPD), patients have irreversible structural changes in the lung causing problems in ventilation and specifically an inability to exhale air rapidly. This results from a variety of causes, including long-term cigarette smoking, inhalation of toxic particles or gases, severe asthma, and autoimmune diseases. Two specific diseases that fall within the COPD category are emphysema and chronic bronchitis.5

Treatment Of C pneumoniae Respiratory Infections

Data are limited on the treatment of respiratory infections due to C. pneu-moniae. Despite the fact that many antimicrobial agents have excellent activity in vitro, as described above, in vitro activity may not always predict in vivo efficacy. Early anecdotal data suggested that prolonged therapy (i.e., at least 2 weeks') was necessary since recrudescent symptoms have been described following 2-week courses of erythromycin and even after 30 days' tetracycline or doxycycline.(3435) However, practically all treatment studies of C. pneumoniae respiratory infection, including pneumonia, bronchitis, and asthma, presented or published to date have used serology alone for diagnosis, essentially limiting themselves to a clinical endpoint. Most studies have followed this premise if the patient has serologic evidence of infection and clinically improves, the organism is presumed to have been eradicated. In 1990, Lipsky et al.(36) Data on efficacy of antibiotic treatment of other respiratory...

Intravenous anaesthetics

Cardiovascular effects of ketamine are accompanied by an increase in plasma noradrenaline (norepinephrine) concentration. Because pharyngeal and laryngeal reflexes are only slightly impaired, the airway may be less at risk than with other general anaesthetic techniques. It is a potent bronchodilator and is sometimes used to treat severe bronchospasm in those asthmatics requiring mechanical ventilation. (See also Dissociative anaesthesia, p. 348.)

Anticholinergics Developed For Specific Uses

These structural features allow the Ipra-tropium molecule to attain a relatively selective bronchodilator effect on the cholinergi-cally innervated airways. By the inhalation route of application, this poorly absorbable quaternary ammonium derivative becomes selective to primarily affect the airway smooth muscle. Another advantage of ipratropium over atropine is that, in contract to the latter, it does not suppress mucociliary function.

Early And Late Childhood

Acrocyanosis Asthma

Tion is prolonged and accompanied by other signs such as stridor, cough, or rhonchi. In the presence of lower airway obstruction such as asthma, expiration is prolonged Childhood asthma is an extremely common condition throughout the world. Children with acute asthma present with varying severity and often have increased work of breathing. Expiratory wheezing and a prolonged expiratory phase, caused by reversible bron-chospasm, can be heard without the stethoscope and are apparent on auscultation.

VT breathing frequency and breath timing

As described in Chapters 1 and 2, in healthy individuals VT is primarily responsible for increases in ventilation at low levels of exercise 97 , with breathing frequency (fR) becoming progressively more important as peak WRs are approached 97, 98 . In COPD patients and also in highly fit subjects with very high ventilatory demands, VT may actually decrease asfR increases 99, 100 . Normal resting Vt varies with body height. At peak exercise, Vt normally plateaus (VT,max) at 50-60 of vital capacity (VC) however, there is considerable variation with an upper limit of the 95 CI 80 5, 15, 24, 50,101 . Early work suggested that the VT,max VC ratio could distinguish restrictive lung diseases from COPD 102 and pulmonary disorders from cardiac disorders 103 . However, more recent work has not demonstrated significant differences in VT,max VC between patients with COPD (44+15 ), interstitial lung diseases (54+11 ), bronchial asthma (56 + 12 ) and heart disease (54+ 12 ), leading to the...

Factors That Modulate ECG and Arrhythmic Manifestations of the Brugada Syndrome

Hypokalemia has been implicated as a contributing cause for the high prevalence of SUDS in the northeastern region of Thailand, where potassium deficiency is endemic (Nimmannit et al. 1991 Araki et al. 2003). Serum potassium in the northeastern population is significantly lower than that of the population in Bangkok, which lies in the central part of Thailand, where potassium is abundant in the food. A recent case report highlights the ability of hypokalemia to induce VF in a 60-year-old man who had asymptomatic Brugada syndrome, without a family history of sudden cardiac death (Araki et al. 2003). This patient was initially treated for asthma by steroids, which lowered serum potassium from 3.8 mmol l on admission to 3.4 and 2.9 mmol l on the seventh day and eighth day of admission, respectively. Both were associated with unconsciousness. VF was documented during the last episode, which reverted spontaneously to sinus rhythm.

The Thorax and Lungs Case Study

Mary is a 25-year-old telemarketer who presents to the emergency room for evaluation of shortness of breath. It started 1 week ago, right after a dust storm. She states that she starts coughing, but then she can't stop, so she feels like she can't breathe after a while. The coughing is so bad that she has vomited afterward. The cough is nonproductive. She denies fever or chills. She has noticed nasal congestion and a clear runny nose. She feels like her ears are stopped up and she has noticed increased sneezing in the past 3 days prior to the onset of the shortness of breath. She also has itchy, watery eyes. She has a childhood history of asthma, which she has outgrown. The last time she had an asthma attack, she was 15 years old. She takes oral contraceptives, but is not on any other medication. She has never had any surgeries. When she had asthma as a child, she was never intubated. Her mother has asthma and her father has high blood pressure.

Inborn Errors of Metabolism

MEKC has been applied to therapeutic drug monitoring. Using MEKC theophylline and its analogues have been separated in plasma. In addition, it has been used to detect and quantitate serum levels of digoxin (44,45). MEKC can also efficiently separate and quantitate antiepileptic drugs that are used in combination, especially ethosuxamide, phenobarbitol, pheny-toin, and carbamazepine (46). (See Chapter 17 for a detailed discussion of the use of CE in therapeutic drug monitoring.) CE has also been used in the clinical and forensic arena (see Chapter 19). In these cases, the use of urine to identify intoxication and or drug abuse of opiates, barbiturates, benzodi-azepines, stimulants, and doping screening is possible within a few minutes (47-51). It is also possible to use CE to screen post mortem fluids for illicit drugs or elevated levels of legal drugs (see Chapter 20). CE has also been applied to determine the tissue concentration of 5-Fluorouracil (5-Fl) in tumor and subcutaneous...

Measurements And Events

Some endpoints assess events, while others provide a measurement of an outcome. Events occur at a specific point in time and their assessment is binary, i.e., either the event has occurred or it has not. Examples of events are death, stroke, cure of infection, progression to AIDS, myocardial infarction, or a flare of asthma. In contrast, measurements have several or many potential values that may change over time. Examples of measurements include blood pressure, strength, weight, CD4+ cell count, tumor size, quality of life scored on a standard scale, and visual acuity. Several factors may affect the decision to use a measurement-based or an event-based endpoint. Measurements can detect a broad range of change in the outcome measure in each patient therefore, measurement-based endpoints will often be more sensitive and yield greater power than event-based endpoints. Measurements, however, may detect very small changes, and therefore may raise more questions about clinical...

Assessment of physical fitness in paediatric chronic lung diseases

EIB is a specific occurrence for bronchial asthma, although it has a low sensitivity 24 . This is the same for several other measures of indirect bronchial responsiveness. However, measures for direct bronchial responsiveness, such as responsiveness to metacholine, have a greater sensitivity but lower specificity. Also, in other chronic lung disorders, a moderate bronchial responsiveness to metacholine may be found, whereas this is not the case for EIB 24 . Therefore, testing specifically for EIB may be of differential diagnostic value, but otherwise has a minor role in the assessment of other chronic lung disorders. Cardiopulmonary exercise testing (CPET) is of value in children with chronic lung disorders, as it provides important information for assessing disease severity and the ability to perform physical exercise. However, it should be noted that the level of physical fitness in children with mild-to-moderate asthma has been found to be comparable to that of healthy children...

Ischemic Heart Disease and Systemic Atherosclerosis Including Stroke and PostAMI Therapy

Beta-blockers are the most effective antianginal drugs available.38 Their pharmacological action is directed toward the beta-1 receptor of the cardiomyocytes in the myocardium. This leads to a slowing of the heart rate and a reduction in myocardial contractility (i.e. negative chronotropic and negative inotropic effects). Thus an efficient reduction of myocardial oxygen demand is achieved, alleviating this trigger of ischemia.39 Cardioselective compounds are generally preferred in patients who have partial contraindications against beta-blockers, such as asthma, peripheral artery disease, and insulin-dependent diabetes mellitus. In addition to providing efficient relief of anginal symptoms, beta-blockers exert an antiarrhythmic and myocardial-protective effect, and are therefore also indicated in post-myocardial infarction patients.38

P2Adrenoceptors in the Heart

The p2-AR subtype is also found in the human heart (Brodde 1991), albeit to a lesser extent than p1 ARs. Agonists for p2-ARs include salbutamol (Kelman et al. 1969), terbutaline (Burnell and Maxwell 1971), and salmeterol (Ullman and Svedmyr 1988). p2-ARs are more responsive to isoproterenol as compared to norepinephrine. When heart transplant patients are given isoproterenol, an increase in heart rate is observed, even in the presence of the highly selective p1 antagonist bisoprolol (Hakim et al. 1997). Since the transplanted heart is not innervated, these observations cannot be due to reflex mechanisms. Interestingly, the greatest densities of p2 ARs are found in the SAN (Rodefeld et al. 1996), which suggests a particularly important role in mediating adrenergic influences on heart rate. This has been demonstrated by in vivo studies Despite the overall lesser amount of p2-ARs in the heart, Pi and p2 AR-stimulation increases heart rate to an equal degree (Brodde 1991 McDevitt 1989)....

Synopsis Of The Novel

Camus's The Plague, divided into five parts, chronicles the yearlong story of Oran, a dismal commercial seaport battling the plague. One fine April day in the 1940s Dr. Bernard Rieux, a 35-year-old physician preoccupied with sending his ailing wife to an out-of-town sanitarium, steps on a dead rat. Police magistrate M. Othon notices others. Later, Parisian journalist Raymond Rambert interviews Rieux for a story about lack of sanitation among the Arab population, but because the publication will compromise the truth, Rieux steers him to the dead rat story instead. Rieux's friend, Jean Tarrou, tells him about seeing more convulsing, dying rats. All but the doctor's mother, who comes to keep house for the doctor and his son, are unsettled by the events she has lived through war, depression, and a husband's death. Dead rats begin appearing by the thousands, then just when a sudden drop in the numbers causes the town to feel hopeful, the concierge M. Michel has fever, thirst, delirium, and...

The Role of Phosphatidylinositol 3Kinases and Lipid Phosphatases in Autophagy

Further support in favor of a role of PtdIns 3-kinase in the control of autophagy was obtained by the discovery that 3-methyladenine, the classical inhibitor of autophagic sequestration,91 proved to be an inhibitor of PtdIns 3-kinase.60,90 This provided a satisfactory explanation for its mechanism of action. Likewise, the cAMP phosphodiesterase inhibitor theophylline is also an inhibitor of PtdIns 3-kinase92 which may account for its ability to inhibit autophagy in hepatocytes.93

Section 2 haplotype Analysis

In the research setting, haplotypes are commonly used to localize a disease-conferring gene or locus. Currently, much interest surrounds the use of genetic association studies because this study design is suggested to be more powerful than linkage studies in localizing susceptibility loci for common diseases (e.g., heart disease, asthma, diabetes, autoimmune disease, or cancer) that have moderate risk. Similar to the linkage study design, an association study design genotypes markers in affected and unaffected individuals, and it is expected that markers which co-occur or are associated with the disease phenotype either contribute to the phenotype or are associated with the disease susceptibility locus. In a candidate gene association study, a gene is chosen for study based on an educated guess of the location (usually by a linkage study), genetic studies in model organisms, or the biology of the disease locus in relation to the disease phenotype. The specific...

Pharmacokinetic Properties Some

Adverse reactions, which are mostly mild and reversible, include headache, dizziness, joint swelling, and leukopenia. Lomefloxacin, sparfloxacin, ofloxacin, and trovafloxacin alatrofloxacin cause photosensitization. Quinolones can affect the central nervous system by two mechanisms (1) accumulation of ingested xanthines, including caffeine and theophylline

Summary and conclusions

The possibility that the immune alterations are secondary to a more central dysfunction led to the formation of new hypotheses about the involvement of the CNS. There is some evidence that CFS patients may have a mild form of hypocortisolism which is associated with a centrally mediated increase in serotonin function. Neuroimaging studies have also found evidence for altered cerebral blood flow in CFS patients, while sleep studies suggest alterations in sleep patterns. However, there is great variability between studies and no distinct abnormality seems to distinguish CFS patients. A disrupted HPA axis seems to be the most plausible hypothesis at this stage as it could account for altered sleep patterns as well as changes in the immune system. However, as neuroendocrine changes similar to those found in CFS patients have been associated with both shift work and stress levels in healthy people, it is possible that the HPA disturbances are a result, rather than a cause of the illness....

Exploring Societys Contributions to Client Problems

As Minuchin and his coworkers began to accumulate research and clinical data and to redefine the problem in family terms, successful interventions involving the entire family became possible. Later research expanded to include asthmatic children with severe, recurrent attacks as well as anorectic children the additional data confirmed for Minuchin that the locus of pathology was in the context of the family and not simply in the afflicted individual (Goldenberg & Goldenberg, 2000, p. 197).

Development Of Rituximab For Targeting Cd20 Cells

Rituximab is a chimeric anti-CD20 mAb (Figure 33.1), containing the mouse variable domains of the mAb 2B8 grafted to the human IgG1 constant domains. Rituximab kills CD20+ cells by several mechanisms, including (1) complement-dependent cellular cytotox-icity, (2) antibody-dependent cellular cytotoxicity, and (3) induction of apoptosis.32 Both early phase II testing and phase II pivotal testing of rituximab at 375 mg m2 per week X 4 in relapsed low-grade NHL demonstrated overall response rates of up to 48 (6 CR). The majority of toxic events were infusion related (hypotension, bronchospasm, rhinitis, pruritis, rash, urticaria, and tumor pain) and decreased with repeated dosing. Human antimouse antibodies (HAMA) were not observed. This led to Food and Drug Administration's approval of rituximab for indolent NHL. Its effect against indolent NHL was greatly enhanced by combining the drug with chemotherapy, with 95 overall response rates and 55 CR in patients receiving CHOP...

Affinity ligands have been described for CCR4

Ccr4 Ccl17

MDC (CCL22) and TARC (CCL17) (see Table 4.1). The role of the mouse ligand analogs has been studied in murine models of asthma. In ovalbumin-sensitized and -challenged mice, an anti-MDC antibody inhibits eosinophil recruitment to the lungs and protects against methacholine-induced bronchial hyperreactivity (168). Additionally, an anti-TARC antibody has been shown to attenuate an OVA-induced inflammation and airway hyper-responsiveness (169). In contrast to these results obtained from the neutralization of CCR4 ligands, the receptor knockout does not show any phenotype different from that of wild-type mice in the same models of allergic lung inflammation (170). In human tissues, CCR4 is expressed in all IL-4-positive cells in the bronchial mucosa of asthmatic patients that have been challenged 24 h before tissues were collected (171).In the same study, CCR4 ligands were found to be highly expressed by the airway epithelium in the same patient population. It has also been suggested that...

Walking for the assessment of patients with chronic obstructive pulmonary disease

Reasons for completing an exercise test include 1) identification of an individual's functional capacity 2) broad identification of the cause of exercise limitation (dyspnoea, leg fatigue, etc.) and 3) measurement of the response to an intervention (e.g. pharmacological or exercise therapy). Field tests are employed less frequently for the accurate diagnosis of the reason for a reported reduction in functional capacity or to identify exercise-induced asthma. These tests are commonly used in order to provide an outcome measure for pulmonary rehabilitation. They should, therefore, ideally have the potential to permit exercise prescription using established principles of exercise training as the field test is often the only exercise test employed. More recently, simple exercise tests have been employed to predict morbidity and mortality. It should be acknowledged, however, that performance of a field-based exercise test does not necessarily indicate that an individual is safe to proceed...

Initial Assessment And Resuscitation

Cardiac arrhythmia frequently accompanies poisoning, e.g. with tricyclic antidepressants, theophylline, -adrenoceptor blockers. Acidosis, hypoxia and electrolyte disturbance are often important contributory factors the emphasis of therapy should be to correct these and to resist the temptation to resort to an antiarrhythmic drug. If arrhythmia leads Rhabdomyolysis may result from prolonged pressure on muscles, from agents that cause muscle spasm or convulsions (phencyclidine, theophylline) or be aggravated by hyperthermia due to muscle contraction, e.g. with MDMA ('ecstasy'). Aggressive volume repletion and correction of acid-base abnormality may be needed, and urine alkalinisation may prevent acute tubular necrosis.

Druginduced myocardial damage

Several drugs of abuse have been associated with increases in cardiac troponin without evidence of ischemia. These include alcohol when heavily consumed (75), cocaine (76, 77), and amphetamines (7). Small clinical studies and case reports have documented increased cardiac troponin concentrations following CO exposure, theophylline overdose, snake bites, and during treatment with fluvastatin (7,78). Two case reports also documented an apparent propofol-induced cardiac and a skeletal muscle rhabdomyolysis both cases resulting in fatality (79).

Serum Sample Preparation

For MEKC, if the drug concentration is high enough the serum can be simply diluted in buffer before injection onto the capillary (direct serum analysis), minimizing the matrix effects. This is because the small amounts of serum are solu-bilized by the micelles of the surfactant. Thormann and colleagues (12,13) have successfully applied this technique to the analysis of several drugs such as theophylline, caffeine, and barbiturates by directly injecting serum. Similarly, we applied this technique in the analysis of the new antiepileptic drug felbamate (1) (see Fig. 1). The simplicity, high resolving power, and the small sample size used for the assay render this method suitable for monitoring the levels of these drugs in pediatric patients (Fig. 1).

Selectivity For Adrenoceptors

The following classification of sympathomimetics and antagonists is based on selectivity for receptors and on use. But selectivity is relative, not absolute some agonists act on both a- and p-receptors, some are partial agonists and, if enough is administered, many will extend their range. The same applies to selective antagonists (receptor blockers), e.g. a Pj-selective adrenoceptor blocker can cause severe exacerbation of asthma (a i2 effect) even at low dose. It is important to remember this because patients have died in the hands of doctors who have forgotten or been ignorant of it.3 a + p effects, nonselective adrenaline is used as a vasoconstrictor (a) with local anaesthetics, as a mydriatic and in the emergency treatment of anaphylactic shock, for which condition it has the right mix of effects (bronchodilator, positive cardiac inotropic, vasoconstriction at high dose). P effects, nonselective (i.e. pt + pj) isoprenaline (isoproterenol). Its uses as bronchodilator (P2), for...

Insights Respiratory Infections

The association between C. pneumoniae and asthma has gained much credence in recent years. D. Hahn has outlined a role for this organism as an inducer of asthma. Although there is some disagreement in the medical profession vis a vis diagnosing asthma versus chronic bronchitis or emphysema, the clinical manifestations such as wheezing, coughing, and shortness of breath are endpoints that can be useful in determining lung dysfunction. An intriguing theory is that chlamydial infection leads to the establishment of nonatopic asthma in some individuals (see ref. 11 for review). Perhaps the most convincing data in support of this is the amelioration of symptoms in patients treated with antibiotics effective against Chlamydia. Clinical studies have demonstrated a more rapid decline in lung function in patients with C. pneumoniae seroreac-tivity. Because of the increasing numbers of reactive airway diseases in recent decades, the possibility of reversing this trend with antibiotics is an...

Helminthic infections

Diethylcarbamazine kills both microfilariae and adult worms. Fever, headache, anorexia, malaise, urticaria, vomiting and asthmatic attacks following the first dose are due to products of destruction of the parasite, and reactions are minimised by slow increase in dosage over the first 3 days.

Innate Immune Cells

NKT cells produce both T helper 1 (Th1) and T helper 2 (Th2) cytokines, depending on their mode of activation, underscoring key regulatory roles for the cytokine milieu and glycolipid antigen repertoire present in the tumor microenvironment. Indeed, NKT cells can undermine tumor rejection in some tumor models through a mechanism that involves transforming growth factor P (TGF-P) production by Gr-1+ myeloid suppressor cells (Terabe et al., 2003). Studies have indicated that the CD4- NKT cells effectuate tumor rejection in the MCA-induced fibrosarcoma and B16F10 melanoma models, whereas CD4 + NKT cells contribute to the pathogenesis of inflammatory diseases (e.g., asthma) by the secretion of IL-4, IL-5, and IL-13 (Akbari et al, 2006 Crowe et al, 2005). A deeper understanding of the factors determining the induction of NKT cell subsets during tumor development is an important goal of further investigation.

Response to intervention

The 6MWT has been widely used in many large cardiorespiratory disease trials in order to explore the benefits of rehabilitation, pharmacological intervention, oxygen supplementation and surgery. Redelmeier et al. 38 proposed that a meaningful difference in performance for patients with COPD was 54 m, thus indicating the level at which the patient would evidence an improvement in functional capacity. For such patients, however, the magnitude of change varies enormously despite similar intervention. It would be expected that the degree of improvement would be much greater after a bout of physical training than after bronchodilator therapy. Troosters et al. 39 reported a mean increase of 52 m in a study of the short- and longer-term benefits of pulmonary rehabilitation delivered over a 6-month period. Results from similar rehabilitation studies confirm this magnitude of change 40, 41 . Rehabilitation in patients with peripheral vascular disease also secured improvements in the...

Airway Hyaluronan General Aspects

Numerous publications in the early 1970s examined the content of hyaluronan in human bronchoalveolar lavage (BAL) from normal and diseased lungs. Increased hyaluronan levels were found in asthmatic and chronic bronchitic patients, as well as in patients suffering from alveolar proteinosis and adult respiratory distress syndromes (13-15). Since hyaluronan is found in the extracellular matrix of the lung parenchyma, many of these studies interpreted an increase of soluble hyaluronan in BAL as a marker of interstitial lung damage

Some Pathophysiology

Asthma, like many of the common chronic disorders (hypertension, diabetes mellitus), is a polygenic disorder and already genetic loci linked to either increased production of IgE or bronchial hyperreactivity have been reported in some families with an increased incidence of asthma. Early in an attack there is hyperventilation so that Pa02 is maintained and PaC02 is lowered but with increasing airways obstruction the Pa02 declines and PaCOz rises, signifying a serious asthmatic episode.

Summary Chlamydia pneumoniae and Lung Remodeling

Taken together, the studies reviewed in this section lay the groundwork for the hypothesis that persistent Cpn infection in lung tissue can accelerate the process of lung remodeling, the hallmark of COPD. Based on this evidence, an expanded model for the role of infection in the development of obstructive airways disease is presented in Figure 3. Since nonatopic asthma (i.e., the asthma syndrome most likely to be caused by infection) may account for up to 50 of cases, Cpn infection could potentially have a major public health impact on asthma, and ultimately perhaps also on the treatment and or prevention of other obstructive airways diseases such as chronic bronchitis and emphysema (COPD).

Pharmacological Basis Of Drug Interactions

Pharmacokinetic interaction the drugs interact remotely from the target site to alter plasma (and other tissue) concentrations so that the amount of the drug at the target site of clinical effect is altered, e.g. enzyme induction by rifampicin will reduce the plasma concentration of warfarin enzyme inhibition by ciprofloxacin will elevate the concentration of theophylline.

Infections Transmitted Through the Respiratory Route

Respiratory tract infections are common, usually mild, and self-limiting, although they may require symptomatic treatment with paracetamol or a nonsteroidal antiinflammatory. These include the common cold (80 rhi-noviruses and 20 coronaviruses), adenoviruses, influenza, parainfluenza, and, during the summer and early autumn, enteroviruses. Special attention should be given to detainees with asthma or the who are immunocompromised, because infection in these people may be more serious particularly if the lower respiratory tract is involved.

Interactions During Metabolism

Cimetidine is an inhibitor of several cytochrome P450 isoenzymes and so potentiates a large number of drugs ordinarily metabolised by that system, notably, theophylline, warfarin, phenytoin and propranolol. Depending on the interacting drug, up to 50 inhibition of metabolism may occur when cimetidine 2000 mg d is taken. Erythromycin inhibits a cytochrome P450 isoenzyme and impairs the metabolism of theophylline, warfarin, carbamazepine and methylprednisolone. The mean reduction in drug clearance is 20-25 . Quinolone antimicrobials inhibit specific isoenzymes of P450 responsible for the metabolism of methylxanthines thus the clearance of theophylline is reduced by ciprofloxacin.

Hh Uman biochemistry

The action of epinephrine and related agents forms the basis of therapeutic control of smooth muscle contraction. Breathing disorders, including asthma and various allergies, can result from excessive contraction of bronchial smooth muscle tissue. Treatment with epinephrine, whether by tablets or aerosol inhalation, inhibits MLCK and relaxes bronchial muscle tissue. More specific bronchodilators, such as albuterol (see figure), act more selec-

Concluding Discussion

Receptors and their endogenous agonists in disease states. Given the known pharmacological properties of cannabis and cannabinoid receptor agonists and the distribution pattern of cannabinoid receptors, initial experiments should perhaps focus on the role of the endogenous cannabinoid system in disorders of cognition, memory, affect, motor control and immune function. The therapeutic potential of cannabinoid receptor ligands as anti-inflammatory agents and analgesics and in the control of glaucoma, bronchial asthma, epilepsy and or gastrointestinal motility disorders also merits attention (Hollister, 1986). Another important goal is to establish more fully the part played by cannabinoid receptors in tolerance. A summary of current information about the pathophysiology of cannabinoid receptors and about their role in the production of cannabinoid tolerance can be found elsewhere (Pertwee, 1997).

Factors Affecting Myocardial Oxygen Supply

Sometimes acute and chronic bronchopulmonary disorders such as pneumonia, bronchitis, emphysema, tracheobronchitis, chronic asthmatic bronchitis, tuberculosis, and primary amyloidosis of the lung affect oxygen extraction and its supply to the heart, causing severe ischemia. Also, if the heart does not work as efficiently as it

Pharmacokinetic and Pharmacological Properties of pBlockers Relative to Choice of Agent

A variety of properties differentiate the various drugs available for therapeutic use as P-blockers (for review, see Shand 1983). The available agents differ in their selectivity for p1 versus p2-AR blockade, with atenolol and metoprolol being among the more p1-selective agents available. p1-Selectivity may help to avoid adverse effects (such as bronchospasm) in at-risk patients however, selectivity is never absolute and caution must still be used. Lipophilic agents are more readily able to cross the blood-brain barrier, potentially more likely to produce central nerve system (CNS) adverse effects but possibly having greater beneficial actions related to inhibition of CNS p-adrenergic neurotransmission. Lipophilic agents also tend to be eliminated more rapidly by hepatic biotransformation and to have shorter half-lives. Some p-blockers, such as propranolol and sotalol, may have direct membrane actions on cardiac ion channels that are independent of p-blockade. In the case of sotalol,...

PAdrenergic Receptors in the Heart

And, more importantly, for the treatment of acute asthma (Sneader 2001). Over time, adrenaline was found to cause varied effects, including both vasoconstriction and vasodilation, but it wasn't until Ahlquist's discovery of a- and P-ARs in 1948 that these varying actions were understood (Ahlquist 1948). A principal target of cardiac sympathetic regulation is the sinoatrial node (SAN), which governs normal cardiac rate and is richly innervated by the SNS. However, all other regions ofthe heart receive sympathetic innervation, which can profoundly influence their electrical function.

CoStimulation Through CD28 A Matter of Cell Fate

Full activation of T cells results in proliferation, which allows clonal expansion specific for the antigenic determinants causative of T cell APC recognition. This requires not only TCR-proximal signalling but also co-stimulation through CD28 with CD80 or CD86 (Acuto and Michel 2003 Rudd and Schneider 2003). CD28-deficient mice or mice treated with antagonists of CD28-CD80 CD86 interaction display reduced responses to an array of immune challenges, including infectious pathogens (Compton and Farrell 2002 King et al. 1996 Mittrucker et al. 2001 Shahinian et al. 1993), allograft antigens (Salomon and Bluestone 2001), graft versus host disease (Via et al. 1996), contact hypersensitivity (Krinzman et al. 1996) and asthma (Kondo et al. 1996). Correspondingly, the lack of CD28-mediated co-stimulation of T cells results in impaired proliferation in vitro and in vivo, reduced T helper cell differentiation (Gudmundsdottir et al. 1999 Lucas et al. 1995) and reduced expression of Th2-type...

Practicality of Conducting the Study

The measurements necessary to obtain a definable endpoint may be unobtainable in neonates and infants. Pulmonary function tests, for example, are not easily performed in subjects under the age of 6 years. This clearly can affect asthma studies and may cause the investigator to use alternative endpoints, such as asthma questionnaires that provide less objective data. Validated, subjective test procedures, such as measurements on a visual analog scale, are obviously impossible when a patient has not yet learned to speak. Hence, methodology, or lack thereof, may be crucial. Furthermore, it was only a short time ago that the clinical laboratory was adapted adequately to use the smaller volume of biological fluids available in pediatric patients to measure drug bioavailability, chemistries, electrolytes, and other parameters needed to evaluate drug safety and efficacy. Even now, many tests do not lend themselves to use in the pediatric population because of blood volume considerations in...

C1inh Et Cannabis

The complaints of difficulty swallowing and breathing sound like the complaints of a hyperallergic individual and or asthmatic. This occurs when there is p-agonist activation of smooth muscles and airway spasm. Further questioning and lung function tests are used to determine if this is an allergic reaction. Lung function is determined by measuring conventional parameters. It turns out that Peter does not have asthma or a known allergy to environmental allergens. Indeed, while these might help explain these latest symptoms, they would not address the issue of the intermittent lip swelling.

Persia And Arabia

Cannabis has had a long association with Persia and Arabia. Indeed the term hashish is Arabian and is taken from the phrase hashish al kief ( dried herb of pleasure ). Several early manuscripts describe the popular use of cannabis for intoxication or medicinal purposes. In the Makhsanul aldawaiya, an ancient Arabic drug formulary, cannabis is described as a cordial, a bile absorber, and an appetizer, and its moderate use prolongs life. It quickens the fancy, deepens thought and sharpens judgement (Chopra and Chopra, 1957). In the Herbarium amboinence written in 1095 AD, Rumphius reported that the followers of Mohammed used cannabis to treat gonorrhoea and asthma. Cannabis was also claimed to reduce bile secretion and diarrhoea, and to alleviate the distress of a strangulated hernia (Chopra and Chopra, 1957).


Amphetamine itself was synthesized in 1887 and first studied as early as 1910, but its stimulant effects were not discovered until about 1930. Amphetamine was independently resynthesized in 1927 by the noted psycho-pharmacologist Gordon Alles in a program to develop synthetic substitutes for ephedrine, a drug then being used as a bronchodilator for the treatment of asthma (6). The central stimulant effects of amphetamine were probably noted about 1930, when it appeared in nasal inhalers in Germany. The first medical use for amphetamine was in the treatment of


The widespread use of IFN-a for the treatment of chronic viral hepatitis has created a poorly understood interrelationship between hepatitis and autoimmunity and autoimmune disorders. This relationship is complex, and involves several co-factors and confounding variables. The autoimmune adverse effects of IFN itself appear to be transient and reversible, and the patient with asymptomatic autoantibodies may experience an unmasking of autoimmune disease while on IFN therapy. Nevertheless, viral eradication may be achieved, and risk-benefit considerations must be evaluated. The presence of an underlying autoimmune disease among chronic viral hepatitis patients is particularly problematic, and the literature suggests that patients with MG, Addison's disease, MS, ITP, allergic asthma, psoriasis, or sarcoidosis may experience disease worsening on IFN therapy (see Table 3). Individuals with IBD may experience transient flares on IFN, but its presence is not an absolute contraindication for...

It was Halmagyi and Cotes50 who first reported the occurrence of arterial hypoxaemia after the administration of bronchodilator drugs such as adrenaline (epinephrine) and aminophylline to patients with asthma. During the next decade similar changes were reported with isoprenaline, salbutamol, and orciprenaline, but it was not clear whether the hypoxaemia resulted from impaired distribution of gas caused by preferential deposition of the aerosol in relatively well ventilated areas of lung, from maldistribution of blood flow secondary to haemodynamic changes, or from impaired hypoxic pulmonary vasoconstriction. Subsequent studies in animals subjected to unilateral ventilation hypoxia showed that bronchodilator drugs such as salbutamol and orciprenaline could inhibit hypoxic vasoconstriction.51,52 Isoprenaline is known to dilate vessels in both normoxic and hypoxic areas of lung, but the other agents have little effect in normoxia and appear to have a specific action on hypoxic...

Shengli Medicine

Prescriptions and their clinical applications (Chapters 10, 11, and 12), including Chaihu Oral Liquid (containing small amounts of saikosaponins and essential oils of Bupleuri radix) and Chaihu Injection (distillate of Bupleuri radix), are used for the treatment of influenza and common cold in China. Xiao-Chaihu-Tang (Sho-Saiko-To in Japanese), an extract made from Bupleurum root, Pinellia tuber, Scutellaria root, jujube fruit, ginseng root, Glycyrrhiza root, and ginger rhizome, is widely used for the treatment of chronic disease, such as hepatitis, asthma, nephrotic syndrome, and cancer. Other prescriptions containing Bupleurum radix, such as Da-Chaihu-Tang (Dai-Saiko-To in Japanese), Chaihu-Guizhi-Tang (Saiko-Keishi-To in Japanese), are also extensively used in China and Japan. They can induce an increase in the levels of tumor necrosis factor-alpha (Yamashiki et al., 1994), stimulate natural killer cell-mediated cytotoxic activity (Kaneko et al., 1994), and enhance immunomodulation.


A 35-year-old female with a history of asthma presents to your office with symptoms of nasal itching, sneezing, and rhinorrhea. She states she feels this way most days but her symptoms are worse in the spring and fall. She has had difficulty sleeping because she is always congested. She states she has taken diphenhydramine (Benadryl) with no relief. She does not smoke cigarettes and does not have exposure to passive smoke but she does have 2 cats at home. On examination, she appears tired but is in no respiratory distress. Her vital signs are temperature, 98.8 F blood pressure, 128 84 mm Hg pulse, 88 beats min respiratory rate, 18 breaths min. The mucosa of her nasal turbinates appear swollen (boggy) and have a pale, bluish-gray color. Thin and watery secretions are seen. No abnormalities are seen on ear examination. There is no cervical lymphadenopathy noted and her lungs are clear. Summary A 35-year-old asthmatic female complains of chronic nasal congestion that is worse in the...


The three xanthines, caffeine, theophylline and theobromine, occur in plants. They are qualitatively similar but differ markedly in potency. Tea contains caffeine and theophylline. Mode of action. Caffeine and theophylline have complex and incompletely elucidated actions, which include inhibition of phosphodiesterase (the enzyme that breaks down cyclic AMP, see p. 191), effects on intracellular calcium distribution, and noradrenergic function. When theophylline (as aminophylline) is used alongside salbutamol in asthma its action adds up to increased benefit to the bronchi, but increased risk to the heart. Pharmacokinetics. Absorption of xanthines after oral or rectal administration varies with the preparation used. It is generally extensive ( 95 ). Caffeine metabolism varies much between individuals (tX 2-12 h). Xanthines are metabolised (more than 90 ) by numerous mixed function oxidase enzymes, and xanthine oxidase. (For further details on theophylline, see Asthma.) Actions on...

Mercuric chloride

A progressive fall in glomerular capillary plasma flow is observed in mercuric chloride-induced acute renal failure although the site of the main histological lesion is the proximal tubule. Studies in the IPRK showed that intense mercuric chloride-induced vasoconstriction could be inhibited by captopril but not enalapril arguing against renin-angiotensin system involvement, with binding of free Hg by the sulphydryl group of captopril suggesting a simpler explanation and supporting possible attack by Hg to tissue thiol moieties as the mechanism for vasoconstriction 194 . However, vasoconstriction was absent in the non-filtering IPRK, suggesting that intraluminal mechanisms might be involved 169 . Adenosine analogues selective for the A1 subclass of adenosine receptors, such as N6-cyclohexyladenosine (CHA), induce vasoconstriction in the IPRK 195 . However, theophylline failed to reverse mercuric chloride-induced vasoconstriction 196 . More recent studies in vivo suggest that increased...

Drug Treatment

This varies with the severity and type of asthma. It is a general rule that the effectiveness of changes in drug and dose should be monitored by serial measurements of the simple respiratory function tests such as peak expiratory flow rate (PEFR) or forced expiratory volume (FEVj). Neither the patients' feelings nor physical examination are alone sufficient to determine whether there is still room for improvement. When an asthmatic attack is severe, arterial blood gases must also be measured. Constant and intermittent asthma The 1997 British Thoracic Society guidelines recommend a five-step approach10 (summarised in Fig. 27.1) to the drug management of chronic asthma. The scheme starts with a patient requiring occasional ( -adrenoceptor agonist and follows an escalating scheme of add-on anti-inflammatory treatment. Points to emphasise are (1) short-acting ( -adrenoceptor agonists are used throughout as rescue therapy for acute symptoms (2) patients must be reviewed regularly as they...


CD23 is another potential target of monoclonal antibody therapy like CD20 and CD5, CD23 is expressed on the overwhelming majority of CLL cells. A chimeric macaque-derived anti-CD23 antibody, p6G5G1, has been developed (154). Although these antibodies have been developed as possible therapies for asthma and other allergic disorders, the ubiquitous expression of CD23 on CLL cells indicates that preclinical studies of these compounds in CLL should be pursued. Recently, in vitro studies of a humanized anti-CD23 monoclonal antibody, IDEC-152, demonstrated that crosslinked IDEC-152 induced apoptosis in fresh CLL cells from five patients. In addition, IDEC-152-induced apoptosis was enhanced in the presence of fludarabine or rituximab (155). These promising preclinical results indicate that phase I clinical studies should be undertaken.

Beta Blockers

Reduction of 2.1 in younger patients.39 This indicates that the use of beta-blockers in elderly patients is even more efficient than in younger patients.40 The number needed to treat in patients aged 65-75 years is 20 to avoid one death within 2 years.41 Despite these positive effects, elderly patients are less often treated with beta-blockers than younger patients. This is in part due to the fact that important contraindications for beta-blockers are more often encountered in elderly patients including asthma, chronic obstructive pulmonary disease, peripheral arterial disease, and the risk of hypoglycemia in patients with diabetes. Furthermore beta-blockers lead more often to hypotension, symptomatic bradycardia, and bronchospasm in elderly compared to younger patients. In patients older than 80 years there is no scientific evidence to use beta-blockers in secondary prevention.

Pulmonary Diseases

The periodontal treatment of a patient with pulmonary disease may require alteration depending on the nature and the severity of the respiratory problem. Pulmonary diseases range from obstructive lung diseases (e.g., asthma, emphysema, bronchitis, and acute obstruction) to restrictive ventilatory disorders that are due to muscle weakness, scarring, obesity or any condition that could interfere with effective lung ventilation.1 Combined restrictive-obstructive lung disease may also develop. 4. In a patient with a histors of asthma, make sure the patient's medication (inhaler) is available.

Management Of Gord

Patients should be advised to lose weight, if it is appropriate, and smokers to quit, as nicotine relaxes the gastro-oesophageal sphincter. Raising the head of the bed by 15-20 cm helps to diminish nocturnal reflux. Patients should be advised to avoid heavy meals and situations predisposing to reflux (such as lying down or prolonged bending within 3 hours of a meal). Drugs that encourage reflux should be avoided if possible, e.g. those with antimuscarinic activity (tricyclic antidepressants), smooth muscle relaxants (nitrates and calcium channel blockers) or theophylline compounds.

Other Causes

There are many other natural disease processes that could theoretically lead to sudden collapse and death. Among them is asthma, a disease that is usually unlikely to lead to sudden death if adequately treated and supervised but that may, if untreated and unsupervised and in stressful circumstances, result in the individual being found dead in their cell. Other disease processes include the development of hemoptysis, from tuberculosis or pulmonary malignancy, or hematemesis, from peptic ulceration or esophageal varices, which can be life threatening and may, because of the bleeding, be considered to be the result of trauma rather than a natural disease process. These cases should present no problem to an experienced pathologist following a full postmortem examination.

Other Considerations

Patients with severe decompensated liver disease usually have associated renal impairment, with obvious consequences for drugs eliminated predominantly by the kidney. Where facilities exist, dosing should be guided by plasma concentration monitoring, e.g. of theophylline, lidocaine and phenytoin.
