Abstract

BACKGROUND/OBJECTIVES: The effects of inflammation on nutritional rehabilitation after starting antiretroviral therapy (ART) are not well understood. We assessed the relationship between inflammation and body composition among patients enrolled in the Nutritional Support for African Adults Starting Antiretroviral therapy (NUSTART) trial in Tanzania and Zambia from 2011 to 2013. SUBJECTS/METHODS: HIV-infected, ART-eligible adults with body mass index (BMI) of <18.5 kg/m(2) enrolled in the NUSTART trial were eligible for this study. Anthropometric and body composition data were collected at recruitment and 6 and 12 weeks post ART and C-reactive protein (CRP) was measured at recruitment and 6 weeks. The relationships between CRP and body composition were assessed using multiple regression. RESULTS: Of the 1815 trial participants, 838 (46%) had baseline and 6-week CRP measurements. Median age was 36 years, 55% were females and median CD4 count was 135 cells/mu l. A one-log reduction in CRP at 6 weeks was associated with increased mid-upper arm circumference (0.45 cm; 95% CI: 0.30, 0.61), calf circumference (0.38 cm; 0.23, 0.54), waist circumference (0.98 cm; 0.59, 1.37), BMI (0.37 kg/m(2); 0.24, 0.50) and fat-free mass (0.58 kg; 0.26, 0.91), but not with fat mass (0.09 kg; -0.17, 0.34). Fat-free mass gains persisted at 12 weeks and were more closely associated with 6-week CRP values than with baseline values. CONCLUSIONS: Reduction in CRP shortly after ART initiation was associated with higher fat-free mass gains. Further studies are warranted to determine whether interventions to reduce systemic inflammation will enhance gains in fat-free mass.
