Abstract
The main objective of this study was to analyze the influence of nutritional state among HIV-1 infected people, according to the different clinical stages referred by the CDC (Control Disease Center of the United States) in 1987, as well as the changes in the concentrations of some biochemical markers linked to nutritional state. A similar study was carried out in a control group with UltramicroELISA non-reagent healthy individuals, anthropometrically classified. Concentrations of total proteins, albumin, cholesterol, triglycerides, urea, uric acid and creatinine were analyzed by sex and clinical group, comparing the levels obtained through a variance study. When comparing HIV-1 asymptomatic infected patients to HIV-1 and HIV-2 non infected people, the results showed a non significant increase in the level of total proteins with a significant decrease of albumin and creatinine, the latter observed only in male patients. In stage IV patients, an important decrease of cholesterol and a significant increase of the triglycerides were found, as well as the lowest albumin levels. Urea and uric acid levels did not experience statistically significant changes. It was concluded that the study of biochemical markers is advisable, since it contributes to the detection by default of malnutrition marginal states in infected individuals.
