ABSTRACT
Despite association with adverse clinical outcome, human immunodeficiency virus (HIV)-associated malnutrition has been relatively refractory to conventional nutrition management. Consequently, a prospective randomized trial was conducted to evaluate a new peptide-based enteral formula (NEF) in contrast to a standard enteral formula (SEF) in patients with HIV infection. Eighty early-stage largely asymptomatic patients were randomized into a dietary regimen supplemented with either a ready-to-feed NEF (18.7% protein, 65.5% carbohydrate, 15.8% fat; 1.28 kcal/ml) or SEF (14% protein, 55% carbohydrate, 31% fat; 1.06 kcal/ml). Patients received 2-3 8-oz cans of the NEF or SEF supplement per day for 6 mo. Parameters evaluated at 0 (baseline), 3, and 6 mo included adherence, weight change, anthropometric measurements, serum biochemical indices, gastrointestinal symptoms, physical performance, and intercurrent health events (including hospitalizations). For the 56 evaluable patients, those supplemented with NEF maintained their body weight significantly (p = 0.04) better, had significantly (p = 0.03) more stable triceps skin-fold measurements, and had significantly (p = 0.04) lower blood urea nitrogen than patients consuming the SEF supplement. Consumption of the NEF supplement was also associated with significantly reduced hospitalizations during the 3- to 6-mo evaluation period (p = 0.02). The NEF supplement was well tolerated and did not result in untoward clinical effects. These data suggest that supplemental use of an NEF provides superior nutritional management compared with an SEF for patients with early-stage HIV infection.
