NUTRITION AND AIDS
Keywords:
nutrition, acquired immunodeficiency syndrome, nutrition assessmentAbstract
The human immunodeficiency virus turns the infected individual susceptible to infections and cancer by preventing the adequate immunologic response. The importance of the nutritional status for an human immunodeficiency virus -positive patient is related to its effects on the immunologic system. Malnutrition, a common condition among these patients, also brings about injuries to the immunologic system, having a synergetic effect with the infections. The depletion multicausality of these patients involves the physiopathology of the disease as well as results from the symptoms provoked by medication. The nutritional requirements, energetic, proteic and of antioxidant nutrients like selenium, Zinc, vitamins A, E, C and B, are increasing in response to both opportunistic infections and to human immunodeficiency virus itself. On the other hand, the signs and symptoms related to lead to food intake reduction. A meticulous nutritional evaluation must be made frequently to allow an early intervention in the nutritional status, particularly in children, because it affects development normal course. Even small weight losses (5%), as well as fat-free cell mass, have been associated to bad prognoses. Aggressive nutritional interventions with the use of supplements are many times needed for the patient 's recovery. Although the nutritional deficiency is not considered as the main cause of the immunologic deregulation presented by human immunodeficiency virus-infected individuals, nutritional status quality is an important helping factor in the treatment and life quality improvement of these patients.
