Hepatitis E Virus Seroprevalence and Viremia in Hemodialysis and HIV Infected Patients in Iran

Background and Aims: Hepatitis E virus (HEV) infection is usually a self-limited viral disease that causes acute hepatitis and may progress to chronic hepatitis in immunosuppressed individuals. It seems that hemodialysis patients and HIV infected people are more exposed to HEV infection. The aim of this study was to evaluate the extent of HEV infection in hemodialysis and HIV infected patients ...

Increased regulatory T cell counts in HIV-infected nonresponders to hepatitis B virus vaccine.

Hepatitis B virus (HBV) coinfection is a main cause of liver-related mortality in human immunodeficiency virus (HIV)-infected subjects. Unfortunately, HIV-infected subjects show a low rate of response to standard HBV vaccination (23%-56%), in contrast to rates >90% found in the general population, and the underlying causes (particularly cellular and molecular causes) are still unknown. We hypot...

Heterogeneity of T Cell Responses to Pandemic pH1N1 Monovalent Vaccine in HIV-Infected Pregnant Women

We investigated the Th1 protective and regulatory T and B cell (Treg and Breg) responses to pH1N1 monovalent influenza vaccine (IIV1) in HIV-infected pregnant women on combination antiretroviral therapy (cART). Peripheral blood mononuclear cells (PBMCs) from 52 study participants were cryopreserved before and after vaccination and analyzed by flow cytometry. pH1N1-specific Th1, Treg, and Breg r...

Enhanced Immune Responses of a Hepatitis C Virus core DNA Vaccine by co-Inoculating Interleukin-12 Expressing Vector in Mice

Background: Hepatitis C (HCV) is a worldwide problem without an effective vaccine with more than 170 million chronically infected people worldwide. DNA vaccines expressing antigenic portions of the virus with adjutants have recently been developed as a novel vaccination technology. Objectives: In the present study, a DNA vaccine expressing HCV core protein was developed with IL12 as a genetic a...
