简要总结
MATCH is an observation study of HIV-infected adults on effective antiretroviral therapy (ART) and demographically matched uninfected adults to evaluate muscle and aging.
详细描述
MATCH is a non-randomized observational longitudinal study. We will recruit HIV infected adults (50 to 65 years old) and demographically matched uninfected control subjects to be followed for 4 years over the course of a 5 year study. The targeted age range of 50-65 is chosen to evaluate aging HIV infected individuals at risk for early frailty in the United States. All subjects will undergo blood draws and physical function assessment, and a subset will undergo a CT scan of muscle and will have a muscle biopsy taken.
A substudy will be performed on a subgroup of HIV-infected and HIV-uninfected men from the main cohort to measure daily physical activity by using an activity tracker.

结局指标
主要结局
Inflammation at baseline and 3 years
时间窗: 3 years
Inflammation at baseline and yearly for 3 years will be assessed by measuring circulating levels of inflammatory cytokines (e.g., CRP, IL6) and soluble monocyte/macrophage biomarkers (e.g., sCD14, sC163). These multiple measurements will be aggregated to arrive at one composite inflammatory score. Outcome will be assessed in association with HIV status and physical function.
