The aim of this study was to evaluate the metabolic abnormalities (dyslipidaemia and insulin resistance) associated with highly active antiretroviral therapy (HAART) in AIDS patients, treated in Campo Grande, Mato Grosso do Sul, Brazil. The patients were distributed in five different groups: Group 1, HIV-infected without antiretroviral therapy; Group 2, with Zidovudine, Lamivudine and Efavirenz or Nevirapine; Group 3, with Zidovudine, Lamivudine and Protease Inhibitor; Group 4, with Stavudine, Lamivudine and Efavirenz or Nevirapine; and Group 5, with Stavudine, Lamivudine and Protease Inhibitor. The lipid and glucose profile were determined and statistics comparison was made. The findings of this study showed significant statistics elevations of total cholesterol and triglycerides levels in patients of Groups 3, 4 and 5, when comparing to patients of Groups 1 and 2. Significant differences were not observed between the groups in the others parameters evaluated: Glucose, HDL cholesterol and LDL cholesterol. Comparing two drugs of same class (NNRTI) through the subgroups II-efavirenz and II-nevirapine, significant differences in the serum levels of total cholesterol, triglycerides and glucose favorable to the subgroup II-NVP were observed. These findings suggest that combinations including Protease Inhibitors and/or Stavudine could cause more adverse metabolic effects, and if possible, should be avoided in patients with others cardiovascular risk factors to prevent the precocious atherosclerosis in AIDS patients receiving HAART.

Certain foods, such as oat bran, soy protein, and fl axseed, have been shown to improve a patient's lipid profi le despite possible increases in uricemia. Thus, a bioactive compound was formulated using these foods to help patients with HIV/ AIDS control metabolic disorders resulting from HAART. Methods: An uncontrolled before and after study was performed. The total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides, and uric acid before and after 3 months of consuming the formulation were compared in patients. The compound was formulated such that 40g (the recommended daily intake) contained approximately 10g of fl axseed, 20g of oat bran, and 10g of textured soy protein. Results: The study population consisted of 139 patients, 31 of whom were included in the fi nal analysis. There were no signifi cant variations between the laboratory results obtained before and after consumption of the compound. Conclusions: The regular consumption of the formulation together with individualized dietary guidance did not reduce lipid levels and did not contribute to an increase in uricemia in the study group. However, new studies with higher doses of the foods that compose the formulation should be encouraged to investigate whether these foods can positively infl uence the lipid profi les of these patients.

The results of this study show that ciprofibrate and rosuvastatin or a combination of both can be considered an effective, safe and well-tolerated lipid-lowering treatment for patients with AIDS on highly active antiretroviral therapy.

Antiretroviral therapy has been associated with hyperlipidemia in AIDS patients. This case illustrates the classic metabolic effects associated to the HAART including protease inhibitors and/or stavudine. It was showed that the management of the HAART-associated dyslipidaemia with conventional antihyperlipidemic therapy may fail, being the switching strategy the best option.
