Herpes simplex viruses type 1 and type 2 HSV-1 and HSV-2 respectively are human herpes viruses constituted by an outer envelope, a tegument, a capsid and a linear, double-stranded DNA. These two viruses are responsible for a variety of different clinical manifestations in humans. HSV-1 and HSV-2 are distributed worldwide, and are transmitted from infected to susceptible individuals during close personal contact. Herpes infections are generally localized in the face and in the trunk in the case of HSV-1, and in the genital area in the case of HSV-2, although an increasing proportion of genital infection could also be due to HSV-1. Herpes infections have been recognized since ancient times. They are very frequent and genital herpes is at present epidemic in the United States 2 . Currently, the prevalence of herpes simplex infection is between 70 and 90 of the world's adult population. It is estimated that over one-third of the world's population have recurrent HSV infections between 3...

Conclusion Sqg

The infectious agents with the most evidence to support an etiological role in atherosclerosis include C. pneumoniae and CMV. However, evidence is mounting for a variety of other potential agents including other herpesviruses, influenza, other specific bacteria such as M. pneumoniae , and chronic infections with common bacterial agents e.g., periodontal disease, chronic bronchitis, chronic urinary tract infection 100 . Future studies are expected to elucidate further the pathophysiological relationship between chronic infection and atherosclerosis and to evaluate the potential of a variety of treatment approaches including antibiotics. Until then, however, a general recommendation for the use of any of these infectious markers during routine cardiovascular risk stratification cannot be made.

CRP as a Marker of Widespread Inflammation

Fig. 3. Complex interplay between inflammatory response and progression ofatherosclerosis. Inflammatory response is indeed observed in patients with ACSs. The stimuli for inflammation, however, are poorly understood. Several stimuli may be involved, including oxidized low-density lipoprotein ox-LDL and other sources of endothelial injury. Localized or systemic infections, in particular from Helicobacter pylori HP , Chlamydia pneumoniae CP , and cytomegalovirus CMV , have been suggested as promoters of enhanced inflammatory response, but their role is controversial. The inflammatory reaction is responsible for the secondary effects of cytokine production liver synthesis of acute-phase reactants. CRP, SAA, and fibrinogen are the most widely studied acute-phase proteins. CRP itself is responsible for amplification ofthe inflammatory response by a direct effect on endothelium, platelets, coagulation, and eventually thrombosis, and the development of acute atherothrombosis further enhances...

Infections in Untreated Patients

Herpesvirus infections, predominantly dermatomal herpes zoster and oral herpes simplex, accounted for about 10 of infections 42,43 . Other infections associated with CLL were generally identified from studies of specific infections and included tuberculosis, salmonellosis, cryptococcosis, and, rarely, pneumocystosis and progressive multifocal leukoencephalopathy. All of these infections are associated with impaired cellular immunity, indicating that hypo GG was not the sole deficiency in host defenses in nontreated and minimally treated patients.

Delayed toxicity

The delayed toxicity profile of 2-CdA in hairy cell leukemia is dominated by its immunosuppressive effects. CD4 lymphocyte counts become suppressed, and remain so for prolonged periods, after a single 7-day continuous course. The most common late infection in all series was recurrent dermatomal herpes zoster. The severity, duration, and clinical sequelae of this CD4 lymphocyte depletion was characterized by Seymour et al. in a cohort of 40 patients with hairy cell leukemia treated with continuous infusion 2-CdA at MD Anderson Cancer Center.18 Prior to therapy, 18 patients had lymphocyte subsets analyzed and the median CD4 count was 743 L range, 58-2201 L with a median CD8 count of 238 L range, 75-2342 L . Within 4 months of treatment, 25 patients had nadir lymphocyte subsets analyzed with the median CD4 count suppressed to 139 L range, 25-580 L , and CD8 to 92 L range, 26-879 L . This suppression was prolonged, with a median time of 40 months until CD4 counts returned to the normal...

Acute toxicity

The major acute toxicity of 2-CdA is myelosuppression. In their long-term follow-up study, investigators at Scripps Clinic noted a 16 incidence of Grade 3 and a 71 incidence of Grade 4 neutropenia in the first 135 consecutive treated patients.5 Ten percent had Grade 3 and 10 had Grade 4 thrombocytopenia. Grade 3 anemia occurred in 20 and Grade 4 in 2 . Forty-two percent developed neutropenic fever, though in only 13 , was an infection documented. Of these, the most common infecting organism was Staphylococcus, usually associated with the indwelling intravenous catheter. Although there were several oral herpetic infections and acute dermatomal herpes reactivations, no fungal infections were found. This high rate of neutropenia with culture negative neutropenic fever was also noted at similar rates in other single-institution series with 2-CdA. Despite the frequency of myelosuppression, additional acute toxicities were uncommon. There were no significant rates of nausea, vomiting,...

Herpes cultures are not useful in the acute management of pregnant women who present in labor or with rupture of membranes. They are helpful in making the diagnosis during the prenatal course, when the patient may develop lesions and the diagnosis is in question. Once a woman has been diagnosed with HSV, the practitioner uses his or her best clinical judgment to assess for the presence of HSV in the genital tract during the time of labor.

HSV infection also induces modifications of the host cell morphology and metabolism. Some of these modifications concern nucleoli - which are the site of ribo-some synthesis - and more particularly ribosomes, which appear strongly modified after infection 17, 19-23 . We hypothesized that ribosomes themselves could be directly involved in the post-transcriptional regulation of cellular and viral gene expression. Therefore, we undertook the identification of ribosomal proteins that are modified and of non-ribosomal proteins that associate with ribosomes upon

Viruses

The genetic material, or genome, of a virus can be DNA or RNA it can be double stranded or single stranded it can be linear or circular. For example, the herpes virus has a double-stranded DNA genome, and the polio virus has a single-stranded RNA genome. The genes of a virus can code for the production of all the proteins required to produce more viruses.

Long propriospinal pathways affecting sympathetic activity are multisynaptic

The majority of spinal sympathetic interneurons projecting monosynaptically to sympathetic pre-ganglionic neurons are located either among or just dorsal to their functionally related populations of sympathetic preganglionic neurons. Not only are the longitudinal distributions of spinal sympathetic interneurons and their related sympathetic preganglionic neurons similar, but the densities of spinal sympathetic interneurons are greatest in or near the spinal laminae that contain their associated sympathetic preganglionic neurons. Thus, Cabot et al. 1994 localized spinal sympathetic interneurons to the sympathetic pre-ganglionic neuron-rich lateral portion of lamina VII and the reticulated lateral portion of lamina V, just dorsal to the intermediolateral column. Clarke et al. 1998 used the retrograde transport of modified Herpes simplex virus to identify spinal sympathetic interneurons that were presynaptic to adrenal sympathetic preganglionic neurons. Infected

Spinal sympathetic interneurons are identified both physiologically and

More recently, spinal sympathetic interneurons have been identified by the retrograde, trans-synap-tic transport of herpes viruses Strack et al., 1989a, b Schramm et al., 1993 Clarke et al., 1998 Tang et al., 2004 . Herpes simplex and pseudorabies virus are two herpes viruses that are rapidly taken up by the axons of sympathetic postganglionic neurons and by the axons of preganglionic neurons projecting to the adrenal medulla. Virus is transported back to the somas of these neurons where it replicates and moves trans-synaptically to the neurons' synaptic antecedents. Thus, virus taken up from a peripheral organ or tissue by sympathetic postganglionic neurons infects the sympathetic pre-ganglionic neurons that synapse on those neurons. Virus replicates in the sympathetic preganglionic neurons, and spinal and brainstem interneurons that synapse on infected sympathetic preganglionic neurons are infected by further retrograde, trans-synaptic movement of virus. Antibodies to the viruses...

The strongest known risk factors for NHL are chromosomal translocations, the inciting cause for which isn't usually clear. Viral infection, e.g., with Epstein-Barr virus, human herpes virus 8, or human T-lymphotropic virus-1 HTLV-1 , and acquired immunodeficiencies due to AIDS or immunosuppressive drugs, for example, have been suggested as causative.

Biology And The Relationship Between Cancer And Aging

In the same way there is a well-characterized remodeling of immune function with advancing age 12. However, the consequences are not fully established even if it is apparent that healthy older individuals are more susceptible to reactivation of tuberculosis or herpes zoster. A clear change in T-cell function with age can be measured in vitro. There is an accumulation of T cells that have cell surface characteristics of memory cells while na ve T cells decrease. Distinct studies suggest that T cells acting as primitive natural killer cells NK cells with phenotype intermediate between T and NK cells increase with ageing. B cell immunity is poorly modified but some data suggest that ageing is associated with reduce level of specific gamma globulin and increased level of polyvalent B cells. The concentration of antibodies specific for foreign antigens declines and can be partially explained by a decrease in the number of specific antibody forming cells and impaired T-lymphocyte help as...

When a modification of the tear film structure occurs, with consequent tear film instability, ocular surface stress will develop, resulting in a clinical condition known as dry eye. The classification of this disorder was carried out in 1995 by the National Eye Institute, dividing dry eye into two different types aqueous layer disorders and tear evaporation disorders 32 . This classification is very useful to focus on the main causative factors of the disorder, although the clinical presentation is often a mix of the two pathogenic pathways i.e., a reduced aqueous production often results in an inadequate lipid layer spreading and in excessive tear film evaporation meibomian gland disease is commonly associated with reduced aqueous secretion by the lacrimal gland . Aqueous layer deficiency is the most common cause of dry eye and is dependent on decreased secretion of the lacrimal glands, although increased evaporation of tears may also be involved. Main causes of tear aqueous...

Saikosaponins and sapogenins, administered i.p., i.v., or s.c., showed nonspecific resistance against Pseudomonas aeroginosa and Listeria monocytogenes infections in mice Kumazawa et al., 1990 the most effective resistance was observed with i.p. administration of saikosaponin-d 1 day before the infection with P. aeroginosa. Effector cells participating in the enhanced protection induced by saikosaponin-d were suggested to be macrophages, a major component of peritoneal cells. The intracellular activity of peritoneal macrophages against P. aeroginosa was suggested to be responsible for the antibacterial activity of saikosaponins. In a recent study Bermejo et al., 2002 of the antiviral activity of saikosaponins, buddlejasaponin IV exhibited antiviral activity against vesicular stomatitis virus RNA virus , but not herpes simplex type I, at concentrations ranging from 20 to 25 jag ml without a cytotoxic effect.

Acyclovir and its analogs probably are the most successful antiviral drugs in use today. They are indicated for herpes simplex I and II and varicella zoster chickenpox . The herpes virus has one of the more complicated viral genomes, coding for over 160 genes. One of these structural genes codes for thyrnidylate kinase, which is different from the mammalian kinase enzyme. The viral enzyme will phosphorylate inactive acyclovir actually a prodrug , producing active acyclovir monophosphate Fig. 7.3 . The latter is phosphory-lated next to the diphosphate and finally the triphosphate, which is the active antiviral drug. None of the mammalian kinases can significantly phosphorylate inactive acyclovir to the active form.

Lung transplantation has become an accepted treatment modality for end-stage lung disease. After lung transplantation, there remains a persistent risk of acute and chronic graft failure, as well as of complications of the toxic immunosuppressive regimen used 96 . Compared to other solid organ transplants, the success of lung transplantation has been severely limited by the high incidence of acute and chronic graft rejection. The frequency and severity of episodes of acute rejection are the predominant risk factors for chronic airway rejection, manifested as obliterative bronchiolitis OB 97,98 . Data from rodent allograft studies as well as from clinical lung transplantation show that the lung, in comparison to other solid organs, is highly immunogenic.

Another important issue is the potential of ES cells to form tetra-carcinomas, because remaining undifferentiated ES cells in grafted cell suspension can continue to divide, forming tumors. For example, Bjorklund et al. 65 grafted a mouse ES cell line into a rat model of PD and reported that five out of 25 grafts formed teratoma-like tumors, with consequential death of the animals. One method for eliminating undifferentiated cells is introducing suicide genes, such as the E. coli gpt and herpes thymidine kinase HSVtk , into the cells prior to transplantation. Differentiated ES cells are resistant to the effects of ganciclovir. Therefore, the presence of a neo-mycin resistance gene in the plasmid vector allows selection of the undifferentiated ES cells out of the cell suspension. Undifferentiated HSVtk-positive cells that continue to proliferate can then be destroyed by the conversion of prodrug nucleoside ganciclovir to its phosphorylated form, which is then incorporated into the DNA...

Treatment of meningitis often is empiric until specific culture data are available. Because of the growing incidence of resistant pneumococci as well as meningococci, the recommended empiric therapy in most areas is a high-dose third-generation cephalosporin given concurrently with vancomycin. In other areas, if the disease presentation is typical for meningococcus with the typical rash or the organism is identified quickly on Gram stain of the CSF, therapy with high-dose penicillin can be started if the meningococcus in that area is known to be sensitive. Ampicillin is added when there is a suspicion of listeriosis. Acyclovir should be started for suspicion of HSV or four-drug antituberculosis TB therapy started if the presentation is suspicious for tuberculous meningitis.

Her abdomen reveals a fundal height of 40 cm. The fetal heart rate is 140 bpm, reactive, and without decelerations. The external genitalia are normal without evidence of lesions. The vagina, cervix, and perianal region appear normal. The vaginal fluid is consistent with rupture of membranes.

Clinical Approach Wzo

Genital herpes is a recurrent sexually transmitted disease that currently has no cure. The two types are HSV-1 and HSV-2. HSV-1 usually affects the epithelium in the oral or facial region above the waist , whereas HSV-2 usually affects the genital region below the waist . However, up to one third of the time, the above-the-waist versus below-the-waist rule does not hold true. HSV is the most common cause of infectious vulvar ulcers in the United States. Primary genital infection has both local and systemic effects. It usually affects people between the ages of 15 and 35 years. After an incubation period of 2 to 7 days, the herpes infection usually induces paresthesias of vulvar skin then formation of vesicles, which become shallow ulcers. Often, the vagina, cervix, and perineal area may be involved.

The ABCB MDRTAP Subfamily

Two half-size members of the subfamily, ABCB2 TAP1 and ABCB3 TAP2 , are transporters associated with antigen presentation TAP and form a functional heterodimer to transport peptides from the cytoplasm into the endoplasmic reticu-lum, from where the presentation of peptide antigens via major histocompatibility complex MHC I starts 76 Fig. 3.2 . A transient complex containing a class I heavy chain- 52 microglobulin 52m heterodimer is assembled onto the TAP molecule by numerous interactions with the ER chaperones calnexin, ERp57, calreti-culin, and the specialized tetherin molecule, tapasin 77 . Most interestingly, virus-infected and malignant cells have developed strategies to escape immune surveillance by affecting TAP expression or function 78 . The immediate-early gene product ICP47 of herpes simplex virus type I binds to the cytoplasmic face of TAP and thereby blocks peptide entry, whereas the ER-resident human cytomegalovirus protein US6 inhibits TAP function by blocking the...

Tumor Immunology 1

The incidence of malignancy in an immunosuppressed population e.g., patients treated with high doses of immunosuppressant drugs following organ transplantation, for autoimmune disorders, or other acquired immunodeficiency disorders AIDS was studied. As hypothesized by Thomas see above , these individuals had a higher incidence of malignant growth. However, while cancers in the general population are frequently solid tumors, in these individuals only the frequency of lymphomas, skin cancers, and Kaposi's sarcomas was increased. It was argued that these unique tumors arose not from a failure of immuno-surveillance but as a direct toxic effect of the drugs and or virus causing immunosuppression. Epstein-Barr virus infection of B cells causing mononucleosis, a self-limiting disease, in the general population can lead to B-cell lymphoma Burkitt's lymphoma in immunosuppressed individuals.

Hivassociated Multicentric Castlemans Disease

Benjamin Castleman first described multicentric Castleman's disease MCD as a case record of the Massachusetts General Hospital, familiar to all the readers of the New England Journal of Medicine, in 1954.110 Interest in MCD has grown in recent years with the AIDS epidemic, since there has been an increased incidence of MCD in HIV-positive patients. This followed the recognition of an association between MCD and AIDS-associated KS, again following initial publication of case reports.4 5 Castleman's disease is divided into localized disease and MCD which is characterized by polylymphadenopathy and multiorgan involvement. The localized form is treated with surgery but the management of MCD is less clear and has a more aggressive course. Histologically, it is divided into the hyalinized vascular form and plasma variant, the former being more common in localized disease and the latter more common in MCD. MCD is associated with Kaposi's sarcoma herpesvirus KSHV infection, which is also...

Targeting the Nucleus using Motorproteins and the Microtubule Network Herpes

Viruses which infect the large, polarized cells of the peripheral nervous system have the most dramatic need for a means of spreading over long distances, since the distance between their site of entry and their site of replication can reach several centimeters in length 12 . Herpes simplex virus type 1 HSV-1 the causative agent of cold sores infects sensory neurons and spreads via synapses. Within a neuron, viral capsids must first move from the synapse, along the length of the axon to the cell body, where replication is possible. Progeny virus must then make the return journey, along the axon to the synapse, where they emerge in order to spread to neighboring cells Figure 19.1 . It has been calculated that were this movement to occur by diffusion alone, a journey of a single centimeter would take 231 years, and so it is essential that herpes virus moves by an active transport mechanism. HSV-1 capsids have long been observed to be aligned with axonal microtubules using the electron...

Viral Vectors

Other viral vector systems currently used for gene transfer, such as herpes simplex viruses HSV and alphaviruses, have had limited application in myocardial gene transfer. The ability of HSV-based vectors to accommodate very large DNA fragments provide an advantage for the transfer of very large genes, such as dystrophin or sarcoglycans for treatment of inherited cardiomyopathies 54 . Alphaviruses are positive-strand RNA viruses based on the Semliki Forest virus SFV and Sendibis virus 55 . These viruses have recently been used for very rapid and efficient transduction of several cells and tissues in vitro 56 . These viruses are capable of expressing transgenes within 24 h of transduction in the heart with minimal cytoxicity, suggesting their potential application for gene manipulation in acute myocardial disease such as MI.

Infection As An Alternate Hypothesis For Ms

Antibodies are found in the CSF and not in the serum, migrate to the cathodal regions on isoelectric focusing IEF gels, and are called oligoclonal bands OCBs . OCBs occur in approximately 90 of MS patients, but are not specific for MS, as such bands are also found in the CSF of patients with a wide variety of CNS infections. In general, the presence of OCBs in CSF is thought to represent an intrathecal immune response to an infectious agent. A number of chronic infections of the CNS are characterized by the presence of OCBs in the CSF. These CNS infections include tuberculosis, syphilis, neuroborreliosis, crypto-coccal meningitis, herpes simplex encephalitis, HTLV-1 myelitis, and subacute sclerosing panencephalitis SSPE . 13,14,33

Herpes Simplex Virus

Herpesviruses are promising vehicles for transferring genes into cells. Among this virus family, herpes simplex virus type 1 HSV-1 is the most extensively studied for potential use in human We found that CLL B-cells are highly sensitive to infection with vectors derived from replication-defective rd HSV-l 29 . CLL B-cells express high levels of herpesvirus entry mediator Hve A, but not HveC, the other known receptor for HSV-1. In contrast to B-cells of normal donors, CLL B-cells are relatively resistant to the cytopathic effects of infection by rdHSV-1 and can maintain high-level expression of the transgene for many days after infection, possibly because of the high-level expression of anti-apoptotic genes, e.g., BCL-2, by CLL cells. Consistent with this hypothesis, we found that transduction of HeLa cells with a retrovirus expression vector encoding BCL-2 rendered HeLa cells resistant to the cytopathic effects of rdHSV-1 29 .

Antimicrobial Prophylaxis

Herpes simplex infections are painful, interfere with nutrition, and may become superinfected with bacterial pathogens. Hence, patients who receive therapy with purine analogs should be considered for prophylaxis with acyclovir or valcyclovir if they have had previous infection 46 . Long-term prophylaxis to prevent herpes zoster infections is probably not necessary since nearly all infection is localized to a few dermatomes.

Herpes Zoster

Herpes zoster shingles results when the viruses pass from the ganglia to the skin along the sensory nerves. It commonly occurs in adults, and the incidence increases in the elderly. Clinically, herpes zoster manifests with erythematous vesicles in the skin, associated with pain and sensory deficits in the dermatomes that correspond to the involved ganglia. Common sites are the thoracic dermatomes, the ophthalmic division of the trigeminal nerve ophthalmic zoster , and the somatosensory branch of the facial nerve otic zoster . Notably, painful radicular neuropathy may occur in the absence of cutaneous changes. Postherpetic neuralgia is often a protracted disabling complication with severe pain and paresthesias. The pathology of herpes zoster is a radiculogangli-onitis with mononuclear cell infiltrates. In severe cases, the ganglia are hemorrhagic and necrotic, and the inflammation extends into the spinal cord.

Clinical Approach Utc

Syphilis is caused by the spirochete T. pallidum. The organism penetrates abraded skin or mucous membranes and then disseminates through the lymphatics and bloodstream to involve almost every organ. Within 1 week to 3 months of inoculation, a chancre usually forms at the site of entrance. Multiple ulcers may form, as in HIV-infected patients, but some patients may not notice the ulceration at all. The chancre of syphilis typically is nonerythematous, with rolled borders and a clean base. It usually is painless, although it may be tender if touched. Other diseases that can cause ulcerations include chancroid however the ulcer in this disease usually is painful, exudative, with ragged borders and a necrotic base, and bleeds easily. The lymph nodes can also suppurate in chancroid, unlike in syphilis. The ulcers in herpes simplex infections typically are painful, grouped vesicles on an erythematous base that eventually ulcerate.

Years are infected. The two types of this virus are HSV-1 and HSV-2. Type 1 usually causes infections in the oral region and type 2 in the genital region however, cross-infection may occur. Recurrence is greater with HSV-2. The primary episode usually is a systemic as well as a local disease, with the patient often complaining of fever or general malaise. Local infection typically induces paresthesias before vesicles erupt on a red base. After the primary episode, the recurrent disease is local, with less severe symptoms. Recurrent herpes ulcers are small and superficial and usually do not scar. The best diagnostic test is viral culture. Rarely the infections are sufficiently severe to warrant hospitalization, such as with encephalopathy or urinary retention. Treatment for immunosuppressed individuals often requires intravenous acyclovir therapy oral acyclovir is effective in suppressing frequent recurrences. Chancroid is a sexually transmitted disease, usually manifesting as a soft,...

Infectious Vasculitis

A number of bacteria and fungi that infect the nervous system often produce an acute inflammatory, necrotizing, or chronic granulomatous vasculitis of the cerebral blood vessels. Spirochetes may infect the blood vessels Treponema pallidum in neurosyphilis and Borrelia burgdorferi in Lyme disease. HIV-associated vasculitis is prone to cause ischemic episodes in both adults and children. Vasculitis of the large cerebral arteries accounts for the hemiplegia that develops contralaterally to a facial or ocular herpes zoster infection. Post varicella vasculopathy is a potential risk for stroke in children.

Acyclovir Acycloguanosine

Acyclovir is an antiviral drug used to treat herpesvirus infection. The basis of its action is that acyclovir resembles part of the guanosine nucleoside and is phosphorylated by the viral enzyme, deoxypyrimidine kinase. The phosphorylated triphosphate form of acyclovir is an inhibitor of the herpesvirus DNA polymerase. A related compound, ganciclovir, H2N works similarly. Uninfected cells do not efficiently phosphorylate acyclovir and ganciclovir, so DNA replication and virus growth are inhibited selectively in infected cells.

Deoxypyrimidine Kinase

Deoxypyrimidine kinase is a pyrimidine salvage pathway enzyme in herpesvirus and is a target for antiviral drugs. Its normal substrates are thymidine and dTMP. The enzyme readily phosphorylates the drugs 5-iododeoxyuridine, acycloguanosine acyclovir , and ganciclovir . When the viral DNA polymerase attempts, in turn, to incorporate them into DNA in place of the corresponding dNTPs all three of the triphosphates of these drugs interfere with DNA replication. Uninfected cells do not efficiently phosphorylate acyclovir and ganciclovir and they phosphorylate 5-iododeoxyuridine only weakly, so DNA replication and virus growth are inhibited selectively in infected cells.

Ganciclovir

Ganciclovir is an antiviral drug used to treat herpesvirus infection. The basis of its action is that ganciclovir resembles part of the guanosine nucleoside and is phosphorylated by the viral enzyme, deoxypyrimidine kinase. The phosphorylated triphosphate form of ganciclovir is an inhibitor of the herpesvirus DNA polymerase. A related compound, acyciclovir, works similarly. Uninfected cells do not efficiently phosphorylate ganciclovir and acyclovir, so DNA replication and virus growth are inhibited selectively in infected cells.

Functional ADA was shown to be co-expressed in proportion to the MDR1 level. In an antitumoral suicide approach, the co-expression of MDR1 and herpes simplex virus thymidine kinase allowed selective killing of MDR1-transduced human tumors transplanted in nude mice Sugimoto et al., 1997 .

Therapeutic Angiogenesisvasculogenesis Promises And Limitations

Adeno-associated virus AAV is a small single-strand DNA parvovirus that is defective, nonpathogenic, and largely diffused in the general population. More than 90 of the parental viral genome is deleted in AAV-based vectors. Consequently, no viral protein is expressed from AAV vectors in transduced cells. Recent advances enhanced the production capability of high-titer stocks of AAV. Accordingly, vectors that express different genes canbe mixed before transduction in order to obtain the simultaneous statement of two or more different proteins in the same tissue. AAV has been shown to infect primate hematopoietic progenitor cells with reasonable efficiency but its use involves coinfection with a helper virus, such as adenovirus or herpes simplex virus. Use of recombinant AAV will require the development of optimized cotransfection and helper plasmid strategies for productive infection. Finally, AAV has a broad host range, but displays an exquisite tropism for nervous and muscular...

Synthesis of Heparin Oligosaccharides Recognized by Herpes Simplex Virus

Heparan sulfate serves as adhesion receptor for bacteria, parasites, and viruses. The negative charges of heparan sulfate can be recognized by viral proteins 154 . Herpes simplex viruses are members of the neurotropic subgroup of the herpes virus family. Infection with herpes simplex virus 1 HSV-1 and herpes simplex virus 2 HSV-2 are most common in humans. HSV-1 binds to cells through interaction of envelope glycoprotein gB and gC with cell surface heparan sulfate. A third viral glycoprotein, gD, interacts with one of multiple specific receptors, which results in a viral entry of the virion envelope with a cell membrane. This fusion requires the concerted action of the three glycoproteins gB, gH, and gL and is triggered by the binding of gD to its cognate receptors. A heparan sulfate octasaccharide 160 that binds to HSV-1 gD was identified Fig. 31 155,156 .

Other investigators have studied pentostatin for patients with relapsed CTCL or PTCL with prominent cutaneous manifestations.104 Of the 24 patients evaluable for response, six 25 patients had CR and 11 46 patients had PR. Ten of 14 71 patients with SS, four of six 66 with tumor stage MF, and three of three with PTCL responded.

Infections Associated With Purine Analog Therapy

The therapy of CLL has changed dramatically with the introduction of the purine analogs. Unfortunately, although these agents are highly efficacious, they are associated with substantial risks of infection even for prolonged periods after cessation of therapy. Fludarabine has been combined with prednisone, which proved to be no more effective than fludarabine alone but was associated with a higher risk of infections 11 . What is most impressive and probably related to reduced CD4 lymphocyte numbers, is the increased frequency of infections that are also seen in AIDS patients such as Pneumocystis carinii, cytomegalovirus, herpesviruses, and Listeria monocytogenes infections 46 . The largest amount of information on infectious complications following purine analog therapy has been obtained from CLL patients receiving fludarabine. Early studies focused on the increased frequency of L. monocytogenes and P. carinii infections 47 . Subsequently, a variety of infections, most of which are...

Conclusions Gyo

Infection is a common complication in patients with CLL owing to the disease and to its therapy. The development of effective chemotherapeutic agents, such as the purine analogs, has increased the frequency and severity of those infections and has changed the spectrum of infecting organisms. Most of infections involve the respiratory tract, but a substantial number involve the central nervous system. Common bacterial pathogens include S. pneumoniae, S. aureus, E. coli, P. aeruginosa, and Klebsiella species. Cryptococcosis is the most common fungal infection and herpes simplex and herpes zoster are the most prevalent viral infections. Less common, but important, pathogens associated with purine analog therapy include L. monocytogenes, P. carinii, EBV, and JC virus. The only prophylactic measure that has been studied in an organized fashion is IVIG, and it should be administered only to selected patients with hypo IgG who have a history of repeated severe bacterial infections.

Viral Infections

Herpes zoster is the most common severe viral infection associated with CLL 48 . Less than 10 of patients experience cutaneous dissemination, and only a few develop visceral dissemination. About 20 suffer from postherpetic neuralgia, and a few develop polyradiculopathy or meningoencephalitis 55,60 . Herpes simplex infections of the circumoral area and oropharynx are more common than herpes zoster but are usually not as severe. A chronic indolent form of orofacial herpes simplex infection has been described in a few patients 61 . Slowly or rapidly progressive local or widespread lymphadenitis and, rarely, visceral dissemination may occur 62 . Occasional patients may develop persistent or recurrent skin lesions after herpes zoster or simplex infection that are caused by infiltration by CLL cells 63 . Several other viral infections have been reported sporadically in CLL patients, including reactivation of hepatitis B, lethal disseminated adenovirus infection, and astrovirus enteritis 70...

Deficiencies in Humoral Immunity

Most patients are deficient in at least one IgG subclass, even some with early-stage disease 22 . The most significant deficiencies are in IgG3 and IgG4 23 . IgG3 is a major component of the humoral response to herpes simplex, which is a common cause of viral infection in CLL patients. IgG4 is an important humoral response to parasitic infections. It has been suggested that selective deficiencies in these two IgG subclasses could be caused by abnormal cytokine production by altered T-cells.

COMPLICATIONS 71 Infections

Infections represent the major cause of morbidity and of mortality of CLL patients. In our series, we observed the same rate of fatal infections in young and old CLL patients 9 . Heavily treated patients and refractory patients, particularly if they are treated with purine analogs, are subgroups with an increased risk of developing infections 42,43 . In young CLL patients receiving intensive treatment, the risk of infectious complications should be always considered. Adequate supportive management, including prophylaxis against herpesviruses, fungi, and Pneumocystis carinii and the use of granulocyte colony-stimulating factor in the presence of neutropenia may reduce the occurrence of fatal infections that could have an adverse impact on the outcome of patients treated with curative intent 44,45 .

Defects in Cellular Immunity

Infections associated with impaired cellular immunity such as tuberculosis, cryptococcosis, listeriosis, and herpes zoster have been reported in CLL patients even before intensive therapy was available and before techniques were available to identify specific components of cellular immunity. Prominent among these abnormalities are decreased concentrations of circulating CD4 lymphocytes, which may occur secondary to the disease process but are a significant consequence of therapy with purine analogs.

DNA plasmid expression vectors can be used for gene transfer. Generally, the transgene is placed downstream of a strong promoter, such as the heterologous cytomegalovirus promoter

General Properties of Herpes Simplex Viruses

Herpes simplex virus type 1 HSV-1 and type 2 HSV-2 are neurotropic viruses that are members of the subfamily a-Herpesvirinae 42 . Both types of HSV are transmissible from person to person via infectious mucosal secretions that come in contact with mucosal epithelia that line surface apertures of the body 9,42,57 . Herpes simplex viruses can cause a variety of diseases including keratitis, cold sores, encephalitis, genital herpes, cutaneous herpes, and meningitis 12, 42 .

On examination he is afebrile, but he has a new right sixth cranial nerve palsy and tremulousness of all four extremities. His CSF has 250 WBCs mm3, with 68 lymphocytes. There are 300 RBCs mm3. Protein levels are high, and the ratio of CSF to serum glucose is very low. He is started on ceftriaxone, vancomycin, and acyclovir. A purified protein derivative PPD placed on admission is positive, and bacterial cultures are negative at 48 hours. Which of the following would help to confirm the diagnosis E. Herpes simplex virus PCR

Info Quj

Herpes simplex virus HSV , a DNA virus, is sequestered inside neurons where it maintains a life-long infection, marked by bouts of recurrent overt infection.

Microbiology

Herpes simplex 1 Herpes simplex 2 Community respiratory viruses HSV and community-acquired respiratory viruses CRV are the most common viral pathogens encountered in the preengraftment period. Autologous and allogeneic HSCT recipients appear to be at similar risk for these viral infections. HSV infections are almost always attributable to reactivation of latent asymptomatic infection in seropositive individuals. In the absence of prophylaxis, 70-80 of seropositive individuals will reactivate HSV in the preengraftment period, with a peak incidence at 2-3 weeks posttrans-plant. HSV type 1 HSV 1 accounts for 85 of episodes and produces gingivostomatitis4 infection in the mouth may spread to the trachea, esophagus or lungs. In the initial posttransplant period, up to half of mouth lesions may be attributable to HSV 1.4 The remaining 15 of HSV reactivation episodes are due to HSV type 2 involving the genitals or other cutaneous sites. Reactivation of other human herpes viruses HHV in the...

Background Pbi

For assessing function and for mapping transcriptional regulatory elements. Indeed, using somatic gene transfer can provide results on spatial and temporal regulation that otherwise could only be obtained by labor-intensive germinal transgenesis, an approach that also requires a great deal of organizational prowess and expense for maintenance of the numerous lines created. Gene transfer into the CNS can be based on cell grafting or direct delivery. For direct delivery, a variety of methods, viral or non-viral, are available. As to the viral methods, in mammalian systems, reports have appeared describing the use of adenovirus-es, lentiviruses, herpes virus, and adenoas-sociated virus-derived vectors. In amphibians, vaccinia virus has also been applied. However, besides their inherent safety problems in therapeutic settings, viral constructs are laborious to construct and verify. Moreover, their production in large quantities is often problematic. For these reasons many groups have...

Disease transmission

Such as babesiosis and human granulocytic ehrlichiosis, have been transmitted by blood, and others such as Lyme disease have that potential Cable and Leiby, 2003 . Some common infectious agents, such as cytomegalovirus and parvovirus B19, are readily transmitted by blood, and though often innocuous may be devastating for particularly vulnerable patients such as pregnant women, premature infants and immuno-suppressed patients. Most blood components are not tested for these agents. Perhaps the greatest worry in the developed world is the silent emergence of some new agent, like HIV in the 1980s, for which recognition and therefore testing may be delayed for years while asymptomatic carriers donating blood spread infection through the blood supply. The most recent example involves emergence of the West Nile virus, an agent that infected thousands of blood donors, resulted in transfusion-transmitted disease, and presented a sudden, unexpected and significant threat to the US blood supply...

Classification Of Aa Based On Etiology And Pathophysiologic Mechanisms

In many respects, clinical and pathophysiologic features of AA suggest a possible infectious etiology. Most commonly, viruses have been implicated. Over the years, many of the suggested agents have been excluded as etiologic factors. The search for AA agents has been extensive. Hepatitis B and A were proven not to be the causative agent for typical AA. Similarly, cytomegalovirus CMV , although certainly capable of producing bone marrow suppression under certain clinical circumstances, such as following stem cell transplantation, is not responsible for idiopathic AA. Certain serologic CMV types have been implicated in transplantation-refractory AA, but these studies have not found application to explain typical AA.48-50 A series of cases clearly

Longterm Complications

The initial concern for patients treated with the purine nucleosides was for an increased risk of infection and the development of second malignancies due to the profound long-term suppression of CD4 and CD8 lym-phocytes.27 28 However, a significant increase in infections is not seen in patients who have responded to treatment and have normal neutrophil counts. In our series, during the 7-year median follow-up, only herpes zoster was seen in remission patients.24

Future Directions

It is becoming clear that the CD137 CD137L interaction is unique and distinct from any other pathway with co-stimulatory properties Figure 1.4 . Given the effect of anti-CD137 mAb in protecting against disease, a major challenge is to streamline and design effective treatments for various autoimmune and non-autoimmune disorders. The fact that a novel regulatory CD11c CD8 cell population expanded by anti-CD137 mAb can block the development of autoimmune diseases provides an additional interest to CD137 signaling. Our laboratory, which was the first to describe this novel cell type, is actively pursuing the question whether these cells can replace anti-CD137 mAb therapy in combating various immune disorders. Our unpublished results thus far look promising and demonstrate that adoptively transferred CD11c CD8 anti-CD137 mAb-expanded cells are on par with anti-CD137 mAb therapy in treating inflammatory bowel disease and halting the spread of herpes simplex virus by selectively targeting...
