AIM: To evaluate the impact of gradual weight loss and the positive effect of sibutramine on metabolic parameters and the levels of serotonin and neuropeptide YY3-36 levels in patients with exogenous constitutional obesity (ECO).
SUBJECTS AND METHODS: The study included 36 patients (24 women and 12 men; mean age 37.56 +/- 0.9 years) with a verified diagnosis of ECO. The height, body weight, waist and hip circumference (WC and HC), and body mass index (BMI) were determined. Adipose tissue content was estimated by a bioimpedance method using an adipose mass analyzer. Serum peptide YY3-36 levels were measured by enzyme immunoassay and blood serotonin concentrations were estimated by high performance liquid chromatography with an electrochemical method.
RESULTS: 12-week sibutramine therapy caused a significant reduction in body weight, WC, HC, and BMI (p < 0.05) in all the patients. At the same time they were found to have a considerable body composition change (total body and visceral fat was decreased, total body water increased, and systemic metabolism was lowered). The mean peptide YY3-36 level was significantly decreased. Sibutramine did not affect the serum content of total serotonin in the sera of patients.
CONCLUSION: Sibutramine used in the combined therapy in patients with ECO contributes to an effective and steady-state weight loss. Sibutramine treatment causes a reduction in total neuropeptide YY3-36, systemic metabolism, and adipose tissue at the expense of the visceral depot.
