Weight Gain With TZD Use- a Common (‘core’) Effect TZDs can increase weight (not edema) 2-8 lbs But 50% with no increased weight or even weight loss- on eucaloric or hypocaloric diet (EVIDENT trial) Obviated with combination with exenatide- no weight gain; actually combination causes nearly as much weight LOSS (~4 lb) as with exenatide alone (~5 lbs/ 30 weeks)

Potential Immunomodulatory Therapy to Prevent / Treat / Reverse Diabetes- (and not just Type 1D) Published online July 26, A promising approach is the use of pharmacological agents, such as orally active chemical chaperones, which can stabilize protein conformation, improve ER folding capacity,and facilitate the trafficking of mutant proteins.110–113 Diabetes, Metabolic Syndrome and Obesity: Targets and Therapy 2014:7 25–34 CLAUDIA CAVELTI-WEDER, Effects of Gevokizumab on Glycemia and Inflammatory Markers in Type 2 DiabetesDiabetes Care 35:1654–1662, 2012 C.
