Leptin replacement therapy (LRT) is effective at improving these pathologies. Currently, there are no data compiling the evidence from the literature, and demonstrating the effect of LRT in LS patients. A systematic review of the MEDLINE and Cochrane Library databases was conducted to identify studies assessing the effect of LRT on metabolic and hepatic endpoints in patients with LS not associated with highly active antiretroviral therapy (HAART) use. Standardized mean differences (SMD) and 95% confidence intervals of pooled results were calculated for overall changes in glucose homeostasis, lipid profile, and hepatic physiology, using an inverse-variance random-effects model. After screening, 12 studies were included for review. Meta-analysis of results from 226 patients showed that LRT decreased fasting glucose [0.75 SMD units (range 0.36-1.13), p=0.0001], HbA1c [0.49 (0.17-0.81), p=0.003], triglycerides [1.00 (0.69-1.31), p<0.00001], total cholesterol [0.62 (0.21-1.02), p=0.003], liver volume [1.06 (0.51-1.61), p=0.0002] and AST [0.41 (0.10-0.73) p=0.01].
