Effects of Testosterone Supplementation on Body Composition in HIV Patients: A Meta-analysis of Double-blinded Randomized Controlled Trials.

Abstract

This study was designed to evaluate the effects of testosterone supplementation (TS) on body composition in patients with HIV and the side effects of TS. A comprehensive literature search strategy was used to retrieve relevant randomized controlled trials (RCTs) examining the effects of TS on body composition. Atotal of 14 eligible studies were included, enrolling 388 and 349 randomized patients in TS and control groups, respectively. The quality of studies included was assessed, and data on total body weight (BW), lean body mass (LBM), fat mass (FM), serum total testosterone (TT), free testosterone (FT) levels, and adverse events were extracted and analyzed using Review Manager software 5.3. Meta-analysis results showed that TS was associated with a small but significant modification in total BW, serum TT, and FT levels in HIV-infected patients and in patients given various drug administrations. TS also significantly increased LBM in male patients, but no significant difference in LBM was observed between female counterparts treated with TS or not. Conversely, TS relative to placebo did not lead to a significant reduction in FM. No significant difference was observed between the two groups in terms of adverse effects. Our findings suggested that TS may be recommended to improve body composition in patients with HIV-related weight loss. However, owing to the high heterogeneity across included trials, further evaluations using large-scale, multi-center, blinded RCTs are needed.
