Phosphatidylethanol and self-reported alcohol consumption among people living with HIV in Thai Nguyen, Vietnam.

Background: Phosphatidylethanol (PEth) is a biomarker for recent alcohol consumption that would ideally validate self-reported alcohol consumption behaviors. We assessed the relationship between PEth and several self-reported alcohol consumption metrics among hazardous alcohol users living with HIV in Vietnam.

Methods: Participants in a three-arm randomized controlled trial assessing two alcohol interventions reported recent alcohol consumption on a 30-day timeline follow-back interview and had a PEth assessment at enrollment, 3 months, and 12 months of the study follow-up.

HIV drug resistance in persons who inject drugs enrolled in an HIV prevention trial in Indonesia, Ukraine, and Vietnam: HPTN 074.

Background: Persons who inject drugs (PWID) have high HIV incidence and prevalence, and may have limited access to antiretroviral therapy (ART) in some settings. We evaluated HIV drug resistance in PWID in a randomized clinical trial (HPTN 074). The study intervention included ART at any CD4 cell count with enhanced support for ART and substance use treatment.
