Efeitos da lipoaspiração abdominal e abdominoplastia sobre níveis circulantes de omentina

Abstract

Objective: Omentin is an adipokine expressed in visceral adipose tissue that has been associated with positive effects on metabolism. The objective of this study was to assess whether changes occur in circulating omentin levels and cardiovascular risk factors after abdominal subcutaneous liposuction with or without abdominoplasty. Materials and methods: Serum omentin levels and cardiovascular risk factors (blood pressure, lipid profile, and waist circumference) were assessed in 21 women at baseline and 8 to 12 weeks after abdominal liposuction with or without abdominoplasty. Weight, blood glucose levels, insulin levels, and the homeostasis model assessment (HOMA) index were also evaluated. Results: At 12-week follow-up, circulating omentin levels had not changed significantly from baseline (P = 0.11; effect size - ES = 0.37). Waist circumference was significantly decreased (P < 0.001; ES = -1.38). Blood pressure, lipid profile, blood glucose levels, insulin levels, and HOMA index were statistically unchanged. Conclusion: Abdominal subcutaneous liposuction, whether alone or with abdominoplasty, was not associated with significant changes in circulating omentin levels or cardiovascular risk factors
