Nutritional effects and support in the patient with acquired immunodeficiency syndrome.
Studies of body composition in acquired immunodeficiency syndrome (AIDS) patients demonstrated body cell mass depletion out of proportion to losses of body weight or fat. The timing of death from wasting was related to the extent rather than the specific cause. However, some patients remain stable for indefinite periods, indicating that wasting is not a constant phenomenon. The development of malnutrition is multifactorial and includes disorders of food intake, nutrient absorption and intermediary metabolism. Nutritional repletion has been demonstrated in several studies. The effect of treating infections that promote wasting was shown in a study of ganciclovir therapy for cytomegalovirus colitis, in which untreated patients underwent progressive wasting whereas treated patients repleted body mass. Total parenteral nutrition had a variable effect upon body composition, with repletion occurring in patients with eating disorders or malabsorption syndromes and progressive depletion occurring in patients with serious systemic infections. Enteral nutrition also can replete body mass in AIDS patients without severe malabsorption. Pharmacologic stimulation of appetite also may lead to weight gain. The results of these studies indicate that nutritional support can improve nutritional status in properly selected AIDS patients.[1]References
