Endotoxin and Intestinal Flora Before and After Gastric Bypass or Banding in Diabetics

Diabetes Mellitus, Type 2 Clinical Trial

Official title:
Comparison Of Endotoxin Concentration And Intestinal Microbiologic Flora Before And After Roux-En-Y Gastric Bypass Or Gastric Banding Surgery In Morbidly Obese Patients With Type 2 Diabetes Mellitus

Clinical Trial Summary

This research project is designed to investigate endotoxin (a toxin present in the wall of certain kinds of bacteria) levels and the type of bacteria present in the intestine before and after Roux-en-Y gastric bypass or gastric banding surgery in patients that meet the classification for morbid obesity (body mass index >40 kg/m2) and type 2 diabetes. It is known that the type of bacteria present in the intestines of normal weight and obese individuals are different, and it is also known that people with obesity and type 2 diabetes have higher levels of endotoxin. It has been shown that the bacteria change over the long run after Roux-en-Y gastric bypass surgery, but the short-term effects are not known and the endotoxin levels after this procedure have never been studied.

Clinical Trial Description

Evidence exists that (i) morbidly obese, T2D patients undergoing RYGB are highly likely to resolve T2D symptoms or dramatically reduce oral and/or insulin requirements, (ii) metabolic endotoxemia may incite the pathologic conditions of low-grade inflammation and subsequently insulin resistance, obesity and T2D, (iii) significant intestinal microbiologic flora differences exist between normal weight and obese/diabetic individuals, and (iv) RYGB alters long-term intestinal microbiologic flora. Therefore, it is logical to evaluate short- and long-term circulating endotoxin concentrations and intestinal microbiologic flora in context with weight loss and restoration of euglycemia to expand our knowledge of the mechanism of the benefits observed following RYGB. ;
