Purpose: To assess the long-term effect of highly active antiretroviral therapy (HAART) on biochemical parameters of HIV-infected patients in University of (137.5 ± 5.1, 3.9 ± 0.5, 104.3 ± 5.7 mmol/l respectively, p < 0.001). Also, levels of creatinine (0.8 ± 0.2 mg/dl), TBil (0.5 ± 0.2 mg/dl), and CB (0.3 ± 0.5 mg/dl) were significantly higher in patients on HAART than those of either the positive (0.7 ± 0.3, 0.4 ± 0.2, 0.2 ± 0.1 mg/dl) or negative (0.7 ± 0.3, 0.3 ± 0.1, 0.2 ± 0.1 mg/dl)
