Monitoring changes in fat-free mass in HIV-positive men with hypotestosteronemia and AIDS wasting syndrome treated with gonadal hormone replacement therapy

DEXA, BIS and D2O techniques demonstrated increases in fat-free mass. The BIS method is less costly, more convenient to use, and had results that more closely matched those from nitrogen balance and retention methods. BIS may be the preferred method to monitor changes in fat-free mass in AIDS patients and patients with malnutrition.
