    Abstract:
    Orlistat lowers lipids and improves insulin sensitivity, but its effect on other metabolic syndrome related parameters is not known. To assess its influence on adiponectin, high sensitive C-reactive protein (hs-CRP) and other metabolic syndrome related parameters, this study enrolled 106 participants in a weight-reduction program and categorized them into a group of 51 who had been treated with orlistat 360 mg/day for one year and a group of 55 age and sex and body mass index (BMI) matched controls. The orlistat group had greater changes in BMI, % body fat (% BF), waist circumference, and insulin resistance, hs-CRP, leptin and adiponectin levels after one year on the program than the controls. After adjusting for % BF and waist circumference, change of serum leptin and adiponectin levels remained significantly different. It was found that orlistat could effectively manage obesity related co-morbidities, especially insulin resistance and atherosclerosis risk. It decreases leptin and increases adiponectin independent of % BF and waist circumference. Therefore, orlistat appears to have anti-diabetic and anti-atherogenic properties and may help prevent metabolic syndrome in the overweight people.
