Resistin levels in morbid obese patients following the biliopancreatic diversion surgery.
Previous studies addressing the changes of resistin concentrations in morbidly obese patients after bariatric surgery have yielded conflicting results. The purpose of the present study was to investigate the changes in serum resistin levels 1 year after biliopancreatic diversion in morbidly obese patients without diabetes mellitus. A cohort of 39 morbidly obese patients without diabetes mellitus was operated. Biochemical and anthropometric evaluation were realized at basal visit and at each visit. The frequency of patients with hypertension and hyperlipidemia was recorded at each visit. Overall the mean patient age was 44.8 ± 14.1, and the mean preoperative BMI was 47.3 ± 6.5 kg/m². After one year of surgery, a significant decrease was observed in BMI, weight, waist circumference, fat mass, blood pressure, total cholesterol, LDL cholesterol, and triglyceride levels. Resistin levels did not change after surgery (5.61 ± 1.93 ng/ml vs. 6.41 ± 3.58 ng/ml; ns). Correlation analysis showed a positive association between basal resistin and weight (r = 0.68, p < 0.01) and fat mass (r = 0.65, p < 0.05). Resistin concentrations did not change after massive weight loss with biliopancreatic diversion in morbid obese patients without diabetes mellitus.
