OBJECTIVE:To analyze the effect of nutritional treatment on metabolic changes caused by the use of antiretroviral therapy in adults with HIV/AIDS.
METHODS:A systematic review of literature was conducted in the PubMed, Lilacs and Cochrane databases, between 1996 and 2010, including crossover and randomized controlled clinical trials performed in adults with HIV/ AIDS using antiretroviral therapy and without opportunistic diseases. The intervention of interest was oral nutritional supplementation and/or a change in lifestyle due to specifi c dietary treatment: dyslipidemia, insulin resistance, lipodystrophy and systemic arterial hypertension. The Jadad scale was used for a qualitative classifi cation of articles.
RESULTS:A total of 385 articles were found, of which seven were included. The interventions used in these studies were as follows: diet, diet and physical exercises, diet and supplementation, and only supplementation. Dyslipidemia was the outcome assessed in all studies. Studies that assessed omega-3 supplementation found a signifi cant reduction in triglycerides. The specifi c diet with omega-3 supplementation showed an increase in HDL-cholesterol. Chrome nicotinate supplementation did not have an effect on dyslipidemia. Changing one's lifestyle, including diet and physical activity, signifi cantly reduced waist circumference, lipodystrophy and systolic blood pressure.
CONCLUSIONS:Reduction in tryglicerides with omega-3 supplementation was the nutritional intervention with the strongest scientific evidence. Prescribing a specifi c diet appeared to be the most adequate intervention to increase HDL-cholesterol. Inferences could not be made about the nutritional treatment of total cholesterol, LDL-cholesterol and insulin resistance. Changes in lifestyle can promote an improvement in lipodystrophy and blood pressure.
