A 47-year-old male patient was admitted because of anemia. He had been diagnosed as non-Hodgkin's lymphoma (Follicular mixed, B cell type, stage ISA) by splenectomy two years before. Bone marrow examination on admission revealed lymphoma cell infiltration and marked decrease in erythroid cells. These findings confirmed relapsed lymphoma with acquired pure red cell aplasia. After several courses of combination chemotherapy, lymphoma cells disappeared from bone marrow, but PRCA was not improved. In this case there were two times remission of PRCA. At first time, acute B type hepatitis occurred during the chemotherapy, anemia improved transiently. At the second time, mild acute hepatitis associated with herpes zoster occurred. Twenty days after hepatic injury, PRCA was improved, and continued in remission state till present day. To disclose the mechanism of PRCA in this case, erythroid colony assay of marrow cells was performed. This showed the presence of inhibitory factor in patient's serum at PRCA state, that was considered to be related to the occurrence of PRCA. These findings suggest that the improvement of PRCA was associated with the changes on immunological condition after acute hepatitis in this case.

Cutaneous infection with Leishmania braziliensis complex requires treatment with parenteral pentavalent antimonials to prevent development of mucocutaneous leishmaniasis. Patients with imported disease are usually managed in hospital because of concerns over drug toxicity. This study describes the clinical features and outcome of infection treated in the UK in an out-patient setting. Thirteen marines (aged 19-35 years) who acquired leishmaniasis in Belize were studied prospectively. Three had at least two lesions (0. 6-3 cm diameter), eight had regional lymphadenopathy and one had localized painless lymphatic thickening. Histology for amastigotes and PCR for Leishmania braziliensis complex was positive in all. Culture was positive in six. Patients received 1.5-2 g (mean 1.7 g) (20 mg/kg) sodium stibogluconate intravenously daily for 20 days. All developed transient musculoskeletal symptoms and asymptomatic hepatitis. Eleven developed biochemical pancreatitis, and one thrombocytopenia. Three developed transient ECG changes and one herpes zoster. There were four device-related infections, two requiring hospitalization (one required surgical drainage of an abscess). All lesions re-epithelialized. A total of 250 bed-days were saved over a 67-day period. These results indicate that in selected patients, out-patient therapy for cutaneous leishmaniasis with parenteral high-dose sodium stibogluconate may be appropriate, provided there is adequate monitoring of therapy.

The postmarketing safety profile of varicella vaccine was evaluated by analyzing selected adverse experience reports temporally associated with the administration of the vaccine. There were 7963 reports voluntarily submitted to Merck for an overall reporting rate of 5.0 per 10000 doses of vaccine distributed. A varicella zoster virus (VZV) identification program detected the presence of the Oka vaccine strain in three individuals with an immune deficiency - two with pneumonia and one with hepatitis - and in three instances of secondary transmission from vaccinees with vesicular lesions to susceptible household contacts. The Oka vaccine strain was present in 23 patients and wild-type VZV was present in 15 patients with herpes zoster. Vesicular rashes that occurred within 2 weeks of vaccination were more likely to contain the presence of wild-type VZV, while vesicular rashes that occurred more than 2 weeks post-vaccination were more likely to contain the Oka vaccine strain. Eleven patients were hospitalized with complications of breakthrough varicella infection.

We examined the prevalence of HIV, general medical, and psychiatric comorbidities by age based on a recent multisite cohort of HIV infected veterans receiving care: the Veterans with HIV/AIDS 3 Site Study (VACS 3). VACS 3 includes 881 adult patients with HIV infection enrolled between June 1999 and July 2000. Providers reported their patients' CDC-defined HIV comorbidities, general medical comorbidities (based on Duke and Charlson comorbidity scales), and psychiatric comorbidity. Mean age of participants was 49 years and 54% were African-American. The most common HIV comorbidities were oral candidiasis (21%), peripheral neuropathy (16%), and herpes zoster (16%). The most common general medical comorbidities included chemical hepatitis (53%), hypertension (24%), and hyperlipidemia (17%). The mean number of HIV and general medical comorbidities experienced by patients were respectively 1.1 and 1.4 (P < .001). Older (> or = 50 years) HIV-infected patients experienced a greater number of general medical comorbidities than those < 50 years (respectively 1.7 versus 1.2, P < .001). There was no significant difference in mean HIV comorbidity number by age. Based on patient report, 46% had significant depressive symptoms (> or = 10 on 10-item CES-D) and 21% reported at-risk drinking (> or = 8 on AUDIT). Providers reported 32% of patients had anxiety, 4% mania, 4% schizophrenia, and 11% cognitive impairment/dementia. General medical and psychiatric comorbidities constituted a higher disease burden for HIV-infected veterans than HIV comorbidities. Whether these comorbidities are due to antiretroviral drug toxicity or are age or lifestyle-associated conditions, the substantial prevalence of these "non-HIV" comorbidities suggest an important role for general medical and psychiatric management of HIV-infected patients.

Visceral dissemination of herpes zoster may follow cutaneous dissemination in immunocompromised patients. The skin is not necessarily the only organ affected and may not even be the presenting organ. Immunohistochemical stains available for routine paraffin-embedded tissue biopsy specimens allow for rapid diagnosis of varicella zoster virus. We describe a patient in whom gastric dissemination of herpes zoster was proven by immunohistochemistry. Unexplained hepatitis, pancreatitis, gastritis, or complaints of abdominal pain in immunocompromised patients with herpes zoster should prompt a high degree of suspicion for visceral zoster and immediate treatment with intravenous acyclovir.

Since the release of amantadine in 1966, other agents designed to fight a diverse range of viral infections have been released. Part I of this two-part article focuses on agents used to manage hepatitis, cytomegalovirus, and herpes infections. In patients with chronic hepatitis B, interferon alfa-2b or lamivudine is the treatment of choice. Pegylated interferon alfa-2a or -2b, along with ribavirin, is standard treatment for patients with chronic hepatitis C. Although treatment of cytomegalovirus infections generally is supportive, there have been reports of severely ill patients who improved after receiving ganciclovir or foscarnet. Oral antiviral agents for initial and recurrent herpes simplex virus infections have been shown to shorten the duration of lesions. Treatment of herpes zoster infections with antiviral drugs shortens the course of infection and decreases symptoms. Studies have shown that antiviral treatment can prevent prolonged post-herpetic neuralgia, although this use remains controversial.

Simian varicella virus (SVV) causes a natural varicella-like disease in nonhuman primates. Epizootics of simian varicella occur sporadically in facilities housing Old World monkeys. SVV is antigenically and genetically related to varicella-zoster virus (VZV), the etiologic agent of varicella (chickenpox) and herpes zoster (shingles) in humans. The SVV and VZV genomes are similar in size and structure, share 70%-75% DNA homology and are co-linear with respect to gene organisation. Simian varicella is a highly contagious disease characterised by fever and vesicular skin rash and may progress to pneumonia and hepatitis. Infected monkeys may resolve the disease within 2 weeks although epizootics are sometimes associated with high morbidity and mortality. SVV, like VZV, establishes life-long latent infection, as indicated by detection of viral DNA within neural ganglia. Subsequently, SVV may reactivate to cause secondary disease and spread of the virus to susceptible monkeys. The relatedness of VZV and SVV and the similarities in the clinical symptoms and pathogenesis of human and simian varicella make SVV infection of nonhuman primates an excellent animal model to investigate VZV pathogenesis and latency, and to evaluate potential antiviral strategies.

The aim of five years (2000-2005) study was to investigate the peculiarities of Herpes Zoster in immunocompromised and immunocompetent patients. For this purpose we have investigated the clinical course of Herpes Zoster, disease duration, complications of disease, as in acute phase as well as postherpetic neuralgia in 74 HIV positive (1st group) and 74 HIV negative (2nd group) groups of patients. In both group of patients we have studied the prevalence of the following complications: 1. Acute complications of Herpes Zoster: a) Neurological: motor neuropathy, cranial neuritis, meningoencephalitis, transverse myelitis. b) Ophthalmic: keratitis, iritis, retinitis, visual impairment c) Cutaneous: bacterial superinfection, scarring, disfigurement. d) Visceral: pneumonitis, hepatitis. e) Multidermatomal. 2. The complications of after resolution of infection: a) Postherpetic neuralgia and various duration of pain associated with postherpetic neuralgia such as : < month, 1-6 months, 6-12 months and >1 year durations. b) Recurrent herpes zoster. Herpes Zoster infection was diagnosed based on clinical symptoms and by detection of VZV specific IgM and IgG by ELISA. HIV infection was diagnosed by ELISA method and was confirmed by Western Blot. We found that Herpes Zoster may develop as in HIV positive as well as HIV negative population. Study showed that severe cases of disease (Herpes Zoster), long duration and rate of complications are much higher in HIV/AIDS than in HIV negative group patients. Rate of hospitalization is also higher in HIV/AIDS patients with Herpes Zoster than in HIV negative patients with Herpes Zoster. Frequency of recurrent Herpes Zoster is much higher in HIV/AIDS patients than in HIV negative patients. The postherpetic neuralgia is very frequent complication for both group (HIV positive and HIV negative) Herpes Zoster patients, but its duration longer in HIV/AIDS patients in comparison HIV negative group. There were no significant difference in disease severity, duration and complications among male and female patients.

The evolution of antiviral therapy began with developments in the management of influenza and herpes simplex keratitis in the 1960s and early 1970s. However, the field exploded with the successful treatment of herpes simplex encephalitis, herpes zoster and genital herpes simplex virus infections, all occurring in the late 1970s and early 1980s. These advances have contributed to the development of therapies for HIV that have transformed the lives of infected patients in recent years. The clinical fruit of all of these research advances has been an armamentarium of drugs that can be used to successfully treat a variety of viral illnesses. In addition to HIV/AIDS, current antiviral therapy focuses primarily on herpesviruses, hepatitis viruses and influenza. Notably, considerable progress remains to be made in these areas. Moreover, a variety of additional viral diseases currently require the development of specific therapies.

In a retrospective cohort of more than 4 million white and black male United States (US) veterans, we explored the role of specific prior autoimmune, infectious, inflammatory, and allergic disorders in the etiology of multiple myeloma (MM) and monoclonal gammopathy of undetermined significance (MGUS). Patients were selected from computerized inpatient discharge records at US Veterans Affairs hospitals. The analysis included 4641 patients (3040 white, 1601 black) and 2046 patients (1312 white; 734 black) with a discharge diagnosis of MM and MGUS, respectively. Using Poisson regression, we calculated age-adjusted relative risks (RRs) and 95% confidence intervals (CIs) for the relationship between MM, MGUS, and specific prior medical conditions. Significantly elevated risks of MM were associated with broad categories of autoimmune (RR, 1.15; 95% CI, 1.02-1.28), infectious (RR, 1.29; 95% CI, 1.20-1.38), and inflammatory disorders (RR, 1.18; 95% CI, 1.10-1.27) and specific prior autoimmune (polymyositis/dermatomyositis, systemic sclerosis, autoimmune hemolytic anemia, pernicious anemia, and ankylosing spondylitis), infectious (pneumonia, hepatitis, meningitis, septicemia, herpes zoster, and poliomyelitis), and inflammatory (glomerulonephritis, nephrotic syndrome, and osteoarthritis) disorders. Risks for MGUS were generally of similar magnitude. Our results indicate that various types of immune-mediated conditions might act as triggers for MM/MGUS development.
