Long term effects of early nutritional support with new enterotropic peptide-based formula vs. standard enteral formula in HIV-infected patients: randomised prospective trial

Nutritional support in HIV infection and AIDS

Weight loss and wasting are common features of HIV infection and AIDS. Patterns of weight loss can be acute or chronic which appear to be related primarily to systemic infections and gastrointestinal pathology, respectively. However, weight loss is not inevitable. and periods of weight stability and weight gain have been documented. Reduced food intake appears to be a major cause of weight loss in HIV infection. Since time of death has been associated with degree of wasting, it seems reasonable to suggest that nutritional support may contribute to enhancing survival and quality of life. All patients should have early access to a qualified dietitian such that assessment of individual situations can be made and appropriate dietary advice given, within a multi-disciplinary approach. Choice of nutritional therapy should be made based on an assessment of the causes of weight loss and an assessment of gut function. Treating infections and alleviating symptoms is vital for ensuring effective nutritional support. Enhancing the energy and protein density of foods and use of oral supplements should be considered if a normal diet alone cannot meet nutritional requirements. Unnecessary dietary restrictions should be avoided. Enteral feeding is indicated for patients unable to meet their needs via the oral route, and in cases of inadequate gut function, parenteral nutrition may be necessary. There is currently insufficient clinical evidence to justify the need for special enteral formulae specifically for patients with HIV infection.
