Objective: To examine the relationship between serum leptin levels and suppression of CD4 count in HIV-infected individuals with highly active antiretroviral therapy (HAART). Subjects and Methods: Thirty seropositive HIV male patients selected from the Infectious Disease Hospital were classified into two groups according to their immunological and virological response to HAART. The first group included 15 male patients with low viral load and low CD4 counts; the second included 15 male patients with low viral load and high CD4 counts. Morning serum leptin and tumor necrosis factor-α levels of HIV patients were measured and correlated with fasting serum insulin, Homeostasis Model Assessment for Insulin Resistance (HOMA-IR), HIV viral load and CD4 count. Results: Serum leptin levels were significantly higher in patients with high CD4 counts than in patients with low CD4 counts (mean serum leptin level 47.3 vs. 10.9 ng/ml, respectively; p < 0.0001). A positive correlation was observed between serum leptin levels and CD4 counts (r = 0.697; p < 0.0001); positive correlations were also seen between leptin levels and fasting serum insulin and HOMA-IR (r = 0.633, p < 0.0001, and r = 0.537, p < 0.003, respectively). Conclusion: Serum leptin level was higher in HIV patients with high CD4 count and correlated with fasting serum insulin and HOMA-IR, thereby indicating that HAART treatment could lead to decreased levels of leptin in HIV patients, which might lead to impaired immunological recovery.
