Abstract Context Gastric bypass (GB) increases postprandial glucose excursion, which in turn can predispose to the late complication of hypoglycemia. Diagnosis remains challenging and requires documentation of symptoms associated with low glucose, and relief of symptom when glucose is normalized (Whipple’s triad). Objective To compare the yield of mixed meal test (MMT) and continuous glucose monitoring system (CGMS) in detecting hypoglycemia after gastric bypass surgery (GB). Setting The study was conducted at General Clinical Research Unit, Cincinnati Children’s Hospital (Cincinnati, OH, United States). Methods Glucose profiles were evaluated in 15 patients with documented recurrent clinical hypoglycemia after GB, 8 matched asymptomatic GB subjects, and 9 healthy weight-matched non-operated controls using MMT in a control setting and CGMS under free-living conditions. Results Patients with prior GB had larger glucose variability during both MMT and CGMS when compared to non-surgical controls regardless of their hypoglycemic status. Sensitivity (71 vs. 47 %) and specificity (100 vs. 88 %) of MMT in detecting hypoglycemia was superior to CGMS. Conclusions Our findings indicate that a fixed carbohydrate ingestion during MMT is a more reliable test to diagnose GB-related hypoglycemia compared to CGMS during free-living state.

Given the fact that diabetes remains a leading cause of end-stage kidney disease (ESKD), multi-aspect approaches anticipating the risk for ESKD and timely correction are crucial. We investigated whether fasting glucose variability (FGV) could anticipate the development of ESKD and identify the population prone to the harmful effects of GV. We included 777,192 Koreans with diabetes who had undergone health examinations more than three times in 2005–2010. We evaluated the risk of the first diagnosis of ESKD until 2017, according to the quartile of variability independent of the mean (VIM) of FG using multivariate-adjusted Cox proportional hazards analyses. During the 8-year follow-up, a total of 7290 incidents of ESKD were found. Subjects in the FG VIM quartile 4 had a 27% higher risk for ESKD compared to quartile 1, with adjustment for cardiovascular risk factors and the characteristics of diabetes. This effect was more distinct in patients aged <65 years; those with a long duration of diabetes; the presence of hypertension or dyslipidemia; and prescribed angiotensin-converting enzyme inhibitors, metformin, sulfonylurea, α-glucosidase inhibitors, and insulin. In contrast, the relationship between baseline FG status and ESKD risk showed a U-shaped association. FGV is an independent risk factor for kidney failure regardless of FG.

AbstractThe letter to the editor made several comments regarding possible methodological issues in the recent article by Lin et al. determining the association between blood glucose variability and postoperative delirium in patients undergoing acute aortic dissection surgery with cardiopulmonary bypass, which is published in Journal of Cardiothoracic Surgery. 2021; 16(1):82. Our concerns included the lack of some important perioperative factors associated with postoperative delirium, the process of establishing multivariate model and the method of using the receiver operating characteristic curve analysis to assess the predictive performance of the standard deviation of blood glucose for the development of POD. We would like to invite the authors to comment on these and believe that clarifying these issues would improve the transparency of this study and interpretation of findings.

Backgraund: Children with type 1 diabetes mellitus (T1DM) need more insulin late in the evening (reverse dawn phenomenon (RDP)), and adolescents need more insulin yearly in the morning (dawn phenomenon (DP)); these cause blood glucose variability. Modern long acting insulin analogues allow to achieve satisfactory glycemic control.Aims: To study the characteristics of insulin therapy in children and adolescents with T1DM using insulin analogues detemir and degludec to overcome blood glucose variability caused by DP and RDP in different age periods.Materials and methods: We analyzed medical documents of 200 patients using detemir, admitted to pediatric endocrinology department in 2013–2019, at mean age 9.0 years (5.4; 13.0), with T1DM for 1.3 years (0.5; 3.0); and medical documents of 50 patients switched to degludec in 2018–2019 at mean age 12.0 years (10.5; 14.5) with T1DM for 3.0 years (1.5; 6.0). Before degludec they were on intensive insulin therapy with glargine (22), detemir (26), or insulin pump (2); 16 patients (32%) presented with clinical characteristics of DP, and 5 (10%) — RDP.Results: 67 children of 108 (62%) aged 1–9 years had redistribution of detemir doses to daytime; 58 adolescents of 92 (63%) aged 10–17 лет — to nighttime. Patients switched to degludec demonstrated decrease in HbA1с from 8.7% (7.8; 9.9) to 8.0% (7.4; 9.0) (р<0.001); fasting blood glucose from 9.8 mmol/l (7.4; 11.7) to 7.7 mmol/l (6.4; 8.6) (р<0.001); within-day variability from 35.2% (31.6; 40.9) to 23.5% (19.7; 28.6) (р<0.001); daily insulin dose from 0.98 U/kg/day (0.82; 1.14) to 0.87 U/kg/day (0.75; 1.07) (р=0.002). Sub-groups of patients with DP and RDP demonstrated decrease in fasting blood glucose (from 11.5 mmol/l (9.8; 13.8) to 7.5 mmol/l (6.6; 9.1) (р<0.001)), and late evening blood glucose (from 11.0 mmol/l (10.2; 11.2) to 8.0 mmol/l (6.7; 9.5) (р= 0.03)) correspondently. Achieved levels of glycemic control did not differ between sub-groups of patients initially using glargine or detemir.Conclusions: Compensation of T1DM may be complicated due to DP and RDP. Switching to degludec allowed to achieve better glycemic control and lowering of blood glucose variability caused by DP and DRP.
