Adipokine Response in Diabetics and Nondiabetics Following the Roux-en-Y Gastric Bypass: A Preliminary Study.

@article{citeulike:1532515, abstract = {INTRODUCTION: The adipocyte influences eating behavior and metabolism via cytokine secretion. We report our findings of adipokine secretion in a cohort of diabetic and nondiabetic morbidly obese patients before and after Roux-en-Y gastric bypass (RYGB). METHODS: Ten morbidly obese subjects who underwent uncomplicated RYGB were studied: five were diabetic and nine were female. Nonfasting plasma levels of adiponectin, resistin, leptin, and tumor necrosis factor-alpha were determined preoperatively and 6 mo postoperatively. C-reactive protein (CRP) was followed as a marker of the metabolic syndrome. RESULTS: The patient age was 42 +/- 11 y, and the preoperative BMI was 50 +/- 6 kg/m(2). The 6 mo BMI fell to 33 +/- 5 kg/m(2) (P < 0.0001), and there were no differences between diabetics and nondiabetics with respect to amount of weight loss. In nondiabetic patients, there were significant increases compared with preoperative levels for adiponectin, resistin, and tumor necrosis factor-alpha; leptin was significantly decreased while CRP was unchanged. CRP and leptin levels were both significantly lower (P < 0.05), while all other protein levels were unchanged in diabetic patients. CONCLUSIONS: At 6 mo postoperation, RYGB significantly altered most adipokine levels for nondiabetic patients. Only CRP and leptin were changed in diabetic patients. All patients lost a significant amount of weight over 6 mo, suggesting a different metabolic effect between nondiabetic and diabetic patients after RYGB.}, address = {University of Minnesota Department of Surgery, Division of Gastrointestinal Surgery.}, author = {Whitson, Bryan A A. and Leslie, Daniel B B. and Kellogg, Todd A A. and Maddaus, Michael A A. and Buchwald, Henry and Billington, Charles J J. and Ikramuddin, Sayeed }, citeulike-article-id = {1532515}, doi = {http://dx.doi.org/10.1016/j.jss.2007.03.036}, issn = {0022-4804}, journal = {J Surg Res}, keywords = {glp1}, month = {July}, posted-at = {2007-08-03 08:34:04}, priority = {2}, title = {Adipokine Response in Diabetics and Nondiabetics Following the Roux-en-Y Gastric Bypass: A Preliminary Study.}, url = {http://dx.doi.org/10.1016/j.jss.2007.03.036}, year = {2007} }
