Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
HIV-infected men and women (18 – 60 yr old) were recruited from the AIDS Clinical Trials Unit, the Infectious Diseases Clinic, and the Volunteers for Health Program at Washington University School of Medicine, St. Louis MO between Jan 2005-Dec 2010. Participants were randomly assigned (1:1) to 4 mo of pioglitazone with or without exercise training.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Exclusion: AIDS diagnosis, non-compliant with anti-HIV medications, unstable CD4+ T-cell count or plasma HIV viremia, illegal drug abuse.

Reporting Groups
  Description
Pioglitazone Pioglitazone (Actos; 30mg/day) for 16 weeks.
Pioglitazone + Exercise Training Pioglitazone (Actos; 30mg/day) plus progressive aerobic and weight lifting exercise training (1.5hr/day x 3 days/wk)supervised and monitored by a personal exercise trainer.

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
No intervention and exercise training only control groups were not included. Intracellular mechanisms were not explored. Relatively small number of participants taking a variety of anti-HIV medication regimens.
