RÉSUMÉ
Late diagnosis of human immunodeficiency virus (HIV) infection remains a challenging issue, especially in young population, which accounts for approximately half of new HIV infections. This study aimed to assess factors associated with late diagnosis of HIV infection in young people. It employed a hospital-based case-control design, conducted during January 2012 through August 2013. A total of 193 patients aged 18-25 years old from 21 hospitals across Thailand were studied. Late diagnosis was defined as presentation when the CD4 cell count was less than 350 cells/µL within 12 months of the first HIV diagnosis, or AIDS-defining event is present within 12 months of the first HIV diagnosis. Factors associated with the late diagnosis of HIV were those who: did not live with their parent (OR 3.87; 95% CI 1.40-10.66), had no children (OR 3.25; 95% CI 1.27-8.31), had their first sexual intercourse at age older than 18 years (OR 4.25; 95% CI 1.27-14.22), had same-age or older partners (OR 3.36; 95% CI 1.39-8.08), were substance users (OR 3.65; 95% CI 1.22-10.88), believed they changed their behaviors after receiving HIV education (OR 2.48; 95% CI 1.02-5.99), and sought care at regional (OR 3.19; 95% 1.31-7.79) or general hospitals (OR 3.34; 95% 1.07-10.35). Strategies for early HIV detection in young people should be reconsidered; particularly the involvement of parents and targeting the right population.

This is a retrospective review of occupational exposure to human immunodeficiency virus (HIV) and subsequent postexposure prophylaxis (PEP) among healthcare workers (HCWs) in King Chulalongkorn Memorial Hospital (KCMH), Bangkok, Thailand. From January 2002 to December 2004, data were collected from incident reports, the hospital's infectious diseases unit and the emergency department. There were 315 reported episodes of occupational exposure among 306 HCWs. Nurses (34.0%) were the HCWs most frequently exposed and percutaneous injury (91.4%) was the most common type of exposure. One-third of the source patients tested were infected with HIV. PEP was initiated following 200 (63.5%) of the 315 exposures and was started within 24h in >95% of cases. The most commonly prescribed PEP regimen was zidovudine, lamivudine and nelfinavir. Fifty-six percent of HCWs given PEP completed a four-week course but the remainder discontinued PEP prematurely due to side-effects, or after negative results from the source, or following informed risk reassessment or from their own accord. No exposed HCW acquired HIV during the study period. Appropriate counselling and careful risk assessment are important in achieving effective HIV PEP among HCWs.

SETTING: Two HIV/AIDS clinics in Bangkok. OBJECTIVE: Although isoniazid (INH) preventive therapy (IPT) can reduce the risk of active TB among HIV-infected individuals, preventive therapy is rarely used in developing countries. The WHO recommends INH prophylaxis for tuberculin skin test (TST) positive HIV positives or for all HIV positives in countries with a high prevalence of latent TB if TST is unfeasible. It is not known whether IPT without TST will affect adherence. DESIGN: Prior to receiving IPT, 914 HIV-infected patients in Bangkok were randomized to TST or not. Adherence, measured by self-report and pill counts, and proportion completing therapy were evaluated. RESULTS: Adherence was 84.5% and 79.7%, by self-report, and 81.8% and 73.9% by pill count, respectively, in PPD-positive and non-TST-screened subjects (adjusted OR 1.44, 95%CI 0.79-2.64 and 1.53, 95%CI 0.45-5.26). The drop-out rate before treatment was 6.3% in the TST-screened and 1.7% in the non-TST screened subjects (OR 3.93, 95%CI 1.18-16.04). CONCLUSION: TST screening was not a predictor of adherence to IPT once therapy began, but it was associated with a higher drop-out rate prior to therapy. Acceptable levels of adherence were observed with both regimens.
