Dietary Intervention Prevents Dyslipidemia Associated With Highly Active Antiretroviral Therapy in Human Immunodeficiency Virus Type 1–Infected Individuals: A Randomized Trial

Objectives rpose of this study was to evaluate the efficacy of dietary intervention on blood lipids of human immunodeficiency virus (HIV)-1–infected patients who are started on highly active antiretroviral therapy (HAART). ound t guidelines recommend diet as first-step intervention for HIV-1–infected individuals with HAART-related dyslipidemia, but there is no evidence from randomized trials to support this recommendation. s -three HIV-1–infected patients, naive from HAART, were randomly assigned to HAART with dietary intervention (diet group, n = 43) or HAART without dietary intervention (control group, n = 40) for 12 months. Diet, according to the National Cholesterol Education Program, was given every 3 months. Before and after intervention, 24-h food records and lipid profile were obtained. Data were analyzed by intention to treat, using mixed-effects models. s esulted in reduction of percentage of fat intake (from 31 ± 7% to 21 ± 3% of calories), while controls presented no change in percentage of fat intake. Plasma cholesterol (from 151 ± 29 mg/dl to 190 ± 33 mg/dl) and low-density lipoprotein cholesterol (from 85 ± 24 mg/dl to 106 ± 31 mg/dl) increased in the control group and were unchanged in the diet group. Plasma triglycerides were reduced by diet (from 135 ± 67 mg/dl to 101 ± 42 mg/dl) and increased in the control group (from 134 ± 70 mg/dl to 160 ± 76 mg/dl). After 1-year follow-up, 21% of patients who received diet had lipid profile compatible with dyslipidemia compared with 68% (p < 0.001) of controls. sions HIV-1–positive individuals naive of previous treatment, diet prevents dyslipidemia associated with HAART.
