OBJECTIVE To study incidence, risk factors, and impact of major opportunistic infections (OIs) after initiation of antiretroviral therapy (ART). METHODS A retrospective cohort study was conducted among naïve HIV-infected patients who were initiated ART during January 2003-December 2004. All patients were followed until 15 months after ART. RESULTS There(More)
OBJECTIVES Although cervical cancer is an AIDS-defining illness, few HIV-infected women are routinely screened for cervical cancer in Thailand. We screened HIV-infected women for cervical cancer as a component of HIV care and assessed high-risk human papillomavirus (HPV) and cervical cancer prevalence. METHODS From July 2003 through February 2004,(More)
BACKGROUND Almost half of all new HIV infections in Thailand occur among low-risk partners of people infected with HIV, so it is important to include people infected with HIV in prevention efforts. METHODS Risk for HIV transmission was assessed among people with HIV attending routine care at the National Infectious Disease Institute in Thailand. Sexual(More)
Seventy human immunodeficiency virus (HIV)-infected patients receiving rifampicin and 70 HIV-infected patients not receiving rifampicin were enrolled to receive 400 mg of nevirapine-based highly active antiretroviral therapy per day. Mean plasma nevirapine levels at 8 and 12 weeks were lower in patients receiving rifampicin (P=.048). However, virological(More)
BACKGROUND The impact of antiretroviral therapy (ART) on survival among patients coinfected with HIV and tuberculosis (TB) has not been well established. METHODS A retrospective cohort study was conducted among HIV-infected patients with TB between January 2000 and December 2004. Patients were categorized into ART+ group (received ART) and ART- group (did(More)
The usage of dried blood spots as specimens for diagnosis and monitoring of HIV-1 infection in Thailand was evaluated.

Susceptibility profiles of medically important fungi in less-developed countries remain uncharacterized. We measured the MICs of amphotericin B, 5-flucytosine, fluconazole, itraconazole, and ketoconazole for Cryptococcus neoformans clinical isolates from Thailand, Malawi, and the United States and found no evidence of resistance or MIC profile differences(More)
OBJECTIVES As Thailand scales up its antiretroviral treatment program, the role of sexually transmitted infection (STI) services to prevent HIV transmission has not been addressed. We provided STI services for HIV-infected women as a component of HIV care and assessed STI prevalence and risk behaviors. METHODS HIV-infected women attending an infectious(More)
