Risk of prevalent HIV infection associated with incarceration among injecting drug users in Bangkok, Thailand: case-control study.

Objectives: To identify risks for HIV infection related to incarceration among injecting drug users in Bangkok, Thailand.

Design: Case-control study of sexual and parenteral exposures occurring before, during, and after the most recent incarceration.

Setting: Metropolitan Bangkok.

Secular trends in the survival of HIV-infected homosexual men in Amsterdam and Vancouver estimated from a death-included CD4-staged Markov model.

Background: The purpose of this study was to investigate secular trends in waiting times in CD4-based stages of human immunodeficiency virus (HIV) disease progression in two cohorts of homosexual men, one in Vancouver and one in Amsterdam. All HIV-positive men with two or more CD4 counts in their AIDS-free period between 1 January 1985 and 1 January 1997 were included in this study. Data regarding clinical AIDS diagnoses (using the 1987 Centers for Disease Control and Prevention [CDC] AIDS case definition) and death were collected through active follow-up, review of hospital records, and municipal/national registries.

HIV-1 prevalence, HIV-1 subtypes and risk factors among fishermen in the Gulf of Thailand and the Andaman Sea.

Objective: Mobile populations are thought to be at high risk for HIV-1 infection. This study aims to determine the prevalence of HIV-1 infection, HIV-1 subtypes and socio-demographic and behavioural risk factors among fishermen in the Gulf of Thailand and the Andaman Sea.

Methods: A cross-sectional survey, consisting of face-to-face interviews and the collection of oral fluid samples, was conducted in Samut Sakorn, Ranong, Songkhla and Traat Provinces, Thailand, between January and April 1998.

Long-term survival after infection with human immunodeficiency virus type 1 (HIV-1) among homosexual men in hepatitis B vaccine trial cohorts in Amsterdam, New York City, and San Francisco, 1978-1995.

Information on long-term survival after infection with human immunodeficiency virus type 1 (HIV-1) is limited. In hepatitis B vaccine trials in Amsterdam, New York City, and San Francisco, 362 gay men were followed up to 18 years (1978-1995). The median survival time from seroconversion was 12.

Avoidance as a predictor of the biological course of HIV infection over a 7-year period in gay men.

The present study prospectively investigated the relation between avoidance coping and active cognitive and behavioral coping and the progression of HIV infection over 7 years in 181 gay men. Findings revealed that for a number of medical and behavioral factors, (a) avoidance coping predicted a lower rate of decline in CD4 cells, (b) the proportional hazard (PH) attributable to avoidance of developing a syncytium-inducing HIV variant was 0.72 (95% confidence interval [CI]: 0.
