Recent data suggest that circulating retinol binding protein-4 (RBP4) is involved in the pathogenesis of insulin resistance in rodents and humans. Moreover, protein C inhibitor (PCI) which specifically binds retinoic acid was found to be increased in myocardial infarction survivors who are also insulin-resistant.Therefore, we investigated the association of insulin resistance with plasma retinol binding factors (RBP4 and PCI active antigen) in nondiabeti...

Recent case reports describe hyperinsulinemic hypoglycemia after gastric bypass. The aim of this study was the assessment of insulin resistance and insulin secretion in non-diabetic morbidly obese patients before and six months after bariatric surgery.In 8 non-diabetic morbidly obese patients (OB:6f/2 m, age:42±3a, BMI:47.29±2.2 kg/m2) and 6 controls (CON:4f/2 m, age:43±0a, BMI:23.8±0.5 kg/m2) we performed a freq...
