BACKGROUND Transfusion-transmissible infectious agents such as human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV) and syphilis are among the greatest threats to blood safety for the recipient. This study aimed to determine the seroprevalence, risk factors and trends of HIV, HBV, HCV and syphilis infections among blood donors over a period of five years at Gonda...

The most important risk factor for HIV infection in North America and Western Europe is homosexual behavior. This article describes a 1988 survey of active male homosexuals in Lima, Peru, that investigated patterns of homosexual behavior and HIV seropositivity.

The association between seropositivity to virus-like particles (VLP) of human papillomavirus (HPV) types 16, 18, 31, 35, or 45 and subsequent cervical HPV infection was examined in 829 women with HIV and 413 risk-matched HIV-negative women. We found no statistically significant differences between HPV-seropositive and HPV-seronegative women in the risk of a new infection with the homologous HPV...

OBJECTIVES This study estimates the prevalence of screened infections: human immunodeficiency (HIV), hepatitis B (HBV) virus, hepatitis C (HCV) virus, brucellosis, and syphilis among Mongolian blood donors. METHODS This report is based on routine data collected from simple questionnaires completed by a sample of consecutive donors visiting the Blood Center between August 2004 and February 200...

BACKGROUND The Step trial raised the possibility that uncircumcised men with pre-existing Ad5 neutralizing antibodies carried an increased risk of HIV infection after vaccination. Thus, understanding Ad seropositivity in humans is important to the development of an AIDS vaccine. Here, we analyze the impact of different Ad5-specific neutralizing antibodies on immune function and clinical outcome...

Abstract Background Thalassemia patients that are conventionally treated by a regular transfusion regimen are exposed to blood born viral infections.The aim of this study was to investigate the seroprevalence of hepatitis B virus (HBV), hepatitis C virus (HCV) , and human Immunodeficiency virus(HIV) among all multitransfused thalassemia patients in west north of Iran. Material and methods A...

Background: HSV2 has an important role in acquiring and transmitting HIV through genital ulcers. This study was conducted to determine the prevalence of this virus in HIV infected subject in Kermanshah, Iran. Methods: This descriptive study was performed among 170 HIV positive patients (case group) and 165 non-HIV cases (control group)) referred to Behavioral Counseling Center of Kermanshah, we...

BACKGROUND Herpes simplex virus type 2 (HSV-2) is a common co-infection among HIV-infected adults that is hypothesized to accelerate HIV disease progression. METHODS We searched Medline, EMBASE, relevant conference proceedings (2006-12) and bibliographies of identified studies without language restriction for cohort studies examining the impact of HSV-2 on highly active antiretroviral therapy...

Stored sera from a cohort of 2397 male factory workers in Harare, Zimbabwe, were screened for herpes simplex virus type 2 (HSV-2)-specific antibodies, to estimate the prevalence and incidence of genital herpes infection and to assess the relation between HSV-2 and human immunodeficiency virus (HIV) acquisition. The prevalence of HSV-2 at enrollment was 39.8%. Correlates of HSV-2 seropositivity ...

BACKGROUND The United States Centers for Disease Control and Prevention (CDC) recently recommended opt-out HIV testing (testing without the need for risk assessment and counseling) in all health care encounters in the US for persons 13-64 years old. However, the overall costs and consequences of these recommendations have not been estimated before. In this paper, I estimate the costs and public...
