Attitudes and perceptions of AIDS clinical trials group site coordinators on HIV clinical trial recruitment and retention: a descriptive study.

HIV-seropositive blacks, Hispanics, women of all ethnicities, and injection drug users (IDUs) have low rates of clinical trial participation. The opinions of research nurses and study coordinators as potential facilitators and barriers to access to clinical trials may contribute to this disparity. Study coordinators and research nurses from the adult AIDS Clinical Trials Group (ACTG) clinical trials units responded to an anonymous computer-based survey comprising multiple choice questions and clinical scenarios.

Absence of sustained hyperlactatemia in HIV-infected patients with risk factors for mitochondrial toxicity.

Background: The prevalence of asymptomatic hyperlactatemia among HIV-infected individuals has been reported to be 4% to 36%. This variability may reflect differences in the definition of and risk factors for hyperlactatemia and/or techniques for venous lactate collection.

Methods: We examined the prevalence of elevated venous lactate collected in accordance with Adult AIDS Clinical Trials Group (AACTG) guidelines among HIV-infected and nucleoside analogue-treated subjects with risk factors associated with hyperlactatemia.
