- Abstract
Hyperproinsulinemia is associated with obesity and type 2 diabetes. We explored the after-meal dynamics of proinsulin and insulin and postprandial effects on glucose and lipids in patients treated with bileopancreatic diversion with duodenal switch (BPD-DS) surgery compared with normal-weight controls [body mass index (BMI)±SD, 23.2 ± 2.4 kg/m2]. Ten previously morbidly obese (BMI±SD, 53.5 ± 3.8 kg/m2) patients free from diabetes who had undergone BPD-DS (BMI±SD, 29.0 ± 5.2 kg/m2) 2 years earlier were recruited. A standardised meal (2400 kJ) was ingested, and glucose, proinsulin, insulin, free fatty acids and triglycerides (TGs) were determined during 180 min. Follow-up characteristics yearly on glucose, lipids, creatinine and uric acid over 3 years after BPD-DS are presented. Fasting glucose and insulin were lower, 0.4 mmol/L and 4.6 pmol/L, respectively, in the BPD-DS group despite higher BMI. Fasting proinsulin was similar in both groups. Postprandial area under the curve (AUC) for glucose, proinsulin and insulin did not differ between the two groups ( p = 0.106–734). Postprandial changes in glucose, proinsulin and insulin were essentially similar but absolute concentrations of proinsulin and insulin were lower in the later phases in the BPD-DS group ( p = 0.052–0.001). Postprandial AUC for TGs was lower in the BPD-DS group ( p = 0.005). Postprandial changes in TGs were lowered in the intermediate phase ( p = 0.07–0.08) and in the late phase (0.002). Follow-up data showed markedly lowered creatinine and uric acid after BPD-DS. BPD-DS surgery induces a large weight loss and lowers, close to normal, postprandial responses of glucose, proinsulin and insulin but with marked lowering of TGs.
