title: Management of nutritional alterations and issues concerning quality of life.
abstract: Malnutrition is common in human immunodeficiency virus (HIV) infection and plays an important role in morbidity and mortality. Malnutrition can affect hospitalizations, disease complications, quality of life, and survival, and has adverse clinical consequences that may be independent of CD4 lymphocyte count. There have been recent advances in knowledge concerning the pathogenesis of malnutrition and the nature of weight loss in HIV patients. The onset of body cell mass depletion may occur early in the infection and predate significant immune deficiency, implying that the virus itself may be involved. Hypogonadism, a common finding in HIV patients, is associated with body composition changes and is involved in body cell mass depletion. In addition, intestinal dysfunction and malabsorption contribute to weight loss in HIV patients. Several studies have evaluated the use of appetite stimulants, enteral and parenteral nutritional support, anabolic agents, and other agents in the management of weight loss and malnutrition in HIV patients. Results of a randomized trial comparing total parenteral nutrition (TPN) and an oral semi-elemental diet (SED) in AIDS patients with malabsorption indicate that the TPN group consumed more calories and gained more weight than the SED group, but the gain was due to increased body fat. The effect of nutritional support on malnutrition and weight loss in HIV patients and potential secondary benefits to quality of life, physical and mental performance, immune function, and disease progression require further study.
