[Nutrition in AIDS]

The infection by HIV continues to be the most aggressive pandemic of our century, with a high economical, social, and health care cost. In the last years the development of new, highly effective therapies has made it possible to change the prognosis, the quality of life, and the survival of many patients. However, the associated malnutrition continues to appear, with dramatic consequences. It affects between 50 and 90% of the seropositive patients. Its origin is multi-factorial and its early detection allows positive therapeutic responses to be obtained, with nutritional repletion, if the correct treatment is given. The future of the nutritional therapeutic approach in patients with HIV infection passes through a combined therapy that includes: nutritional education, drugs, and nutritional support.
