Effects of exercise training and statin on hemodynamic, biochemical, inflammatory and immune profile of people living with HIV: a randomized, double-blind, placebo-controlled trial.

BACKGROUND: The aim of this study is to evaluate the effect of exercise training (ET) and statins on the hemodynamic, biochemical, inflammatory and immune profile of people living with HIV (PLHIV).

METHODS: This was a randomized, double-blind, placebo-controlled clinical trial in which 83 PLHIV were assigned to either placebo (PL), statins (STA), placebo + ET (PLET), or statins + ET (STAET) groups. Volunteers assigned to STA and STAET groups were administered 10 mg of rosuvastatin, whereas the PL and PLET groups were administered a placebo. The PLET and STAET groups performed ET three times a week. Before and after the 12-week follow-up, volunteers underwent blood collection to assess the biochemical, inflammatory, and immune profile.

RESULTS: There were significant time x group interaction effects (P<0.05) for all variables except for diastolic blood pressure. The PLET and STAET groups had significantly (P<0.05) decreased systolic blood pressure, resting heart rate, fasting glucose, glycated hemoglobin, fasting insulin, homeostatic model assessment for insulin resistance, creatine kinase, lactate, and TNF-α levels, and increased adiponectin, CD4⁺, and CD8⁺ levels. There was also a significant group effect (P<0.05) for CK levels among the exercised (PLET and STAET) and STA groups. The latter had a significant increase in fasting glucose (P<0.05) and creatine kinase (P<0.05).

CONCLUSIONS: ET improved the hemodynamic, biochemical, inflammatory, and immune profile of PLHIV and this effect was not dependent on the use of statins.
