There have been reported cases of long-term symptomless human immunodeficiency virus type 1 (HIV-1) infection, but it is not clear whether the benign course of infection was due to host, viral, or other unknown factors. During follow-up of subjects with transfusion-acquired HIV-1 infection in New South Wales, Australia, we identified a group of 6 subjects(More)
The relationship between the presence and severity of AIDS dementia complex (ADC) and the levels of human immunodeficiency virus type 1 (HIV-1) RNA in cerebrospinal fluid (CSF) were assessed. Nineteen patients with ADC (stages 1-3), 6 without ADC (group 1), and 10 (group 2) without ADC but with cryptococcal meningitis or progressive multifocal(More)
BACKGROUND Early detection and treatment of bacterial sexually transmitted infections has been advocated as an HIV prevention strategy. AIM To inform screening guidelines, the incidence and risk factors for urethral and anal gonorrhoea and chlamydia were studied in a prospective cohort of community-based HIV negative homosexual men in Sydney, New South(More)
OBJECTIVES To describe point prevalence of HCV antibody and relevant risk behaviour among people who inject drugs and who attended selected needle and syringe programs throughout Australia in 1995, 1996 and 1997. DESIGN AND SETTING Repeated cross-sectional surveys of one week's duration were carried out in 21, 20 and 23 needle and syringe program sites(More)
We examined sexual behavior as a risk factor for Kaposi's sarcoma-associated herpesvirus (KSHV) infection and examined the relation between KSHV seropositivity and development of KS in cross-sectional and cohort studies of 130 homosexual men diagnosed with AIDS in Sydney, Australia during the period from 1991 to 1993. KSHV serology was measured using(More)
BACKGROUND Pharyngeal gonorrhoea is common in homosexual men and may be important in maintaining community prevalence of anogenital infections. METHODS From 2003, all participants in the Health in Men cohort of HIV-negative homosexual men in Sydney were offered annual pharyngeal gonorrhoea screening by BD ProbeTec nucleic acid amplification (NAAT) assay(More)
OBJECTIVE To determine the prevalence and risk factors for hepatitis C virus (HCV) infection in a cohort of homosexually active men, with particular reference to assessing sexual transmission. DESIGN Prevalence based on cross-sectional testing for HCV (c100 protein) antibody in a cohort using sera stored between 1984 and 1989, and assessment of risk(More)
This study used curve-fitting techniques to detail the dynamics of human immunodeficiency virus (HIV)-1 and its relationship to circulating T lymphocyte changes in a cohort of 41 male patients (mean age 36+/-7 years) infected with HIV-1. The following characteristics of viral kinetics were obtained: virus load peak, 6. 35+/-0.71 log10 RNA copies/mL at(More)
Antiretroviral therapy commenced during primary human immunodeficiency virus type 1 (HIV-1) infection (PHI) may limit the extent of viral replication and prevent early loss of HIV-specific CD4 lymphocyte function. We studied the effect of current standard therapy (2 nucleoside analogues and a protease inhibitor) in 16 patients with symptomatic PHI. In the(More)
BACKGROUND/OBJECTIVES Higher levels of sexual risk behaviours have been reported in HIV positive than in HIV negative homosexual men. In clinic based studies, higher rates of sexually transmitted infections (STIs) have also been reported. We compared rates of common STIs between HIV positive and HIV negative homosexual men from two ongoing community based(More)
