WEIGHT-GAIN ASSOCIATED WITH PROTEASE INHIBITOR THERAPY IN HIV-INFECTED PATIENTS

Weight loss and wasting are significant complications of HIV disease. HIV protease inhibitor therapy promotes clinical, immunologic and viro logic improvement in HIV-infected patients. In this study, we sought t o determine the specific effect of HIV protease inhibitors on patient weight. Ten consecutive HIV patients were treated with protease inhibi tor-containing regimens over six months. CD4 T-cell counts, plasma vir al load levels and bariatric changes were monitored during the study. Patients experienced a mean weight gain of 19 pounds (P = 0.006). Ther e was a significant increase in mean CD4 T-cell count (P = 0.008) and a significant decrease in mean viral load level (P = 0.004), The incre ase in CD4 T cells did not correlate with weight gain, whereas the dec rease in viral load did show a significant correlation with the weight increase (P = 0.003). The mechanism of protease inhibitor-induced wei ght gain is discussed, The medications may also be useful for wasting diseases unrelated to HIV.
