The pilot study of DXA assessment in chinese HIV-infected men with clinical lipodystrophy.
The aim of this study was to evaluate human immunodeficiency virus (HIV)-infected patient's body composition changes by dual-energy X-ray absorptiometry (DXA) and to analyze factors associated with lipodystrophy (LD). Total-body composition was measured by DXA in HIV-infected men and healthy men. HIV-infected men were divided into LD patients and non-LD patients according to whether they were complicated with LD. Healthy men were selected as controls. Fat mass (FM) of HIV-infected patients correlated negatively with the duration of HIV infection and with the duration of highly active antiretroviral therapy regimen (r(s)=-0.448 and -0.563; p=0.032 and 0.000, respectively). Multiple linear regression results showed that FM had positive correlation with weight and bone mineral content (BMC) and had negative correlation with lean mass (LM). Total body and regional FMs were found to be significantly different among LD patients, non-LD patients, and controls-the lowest in LD patients and the highest in controls (p<0.05). Total body, trunk, and leg BMCs of LD patients were lower than those of controls (p<0.05). Lumbar bone mineral density of LD patients was lower than that of non-LD patients and controls (p=0.04 and 0.007). LM of LD patients was higher than that of non-LD patients, and trunk LM had statistical difference between the 2 groups (p=0.003). Applying DXA to assess HIV-infected patient's body composition changes could provide objective information for physicians to prevent LD and osteoporosis.
