Abstract Context Impaired awareness of hypoglycemia (IAH), resulting from habituation to recurrent hypoglycemia, can be reversed by strict avoidance of hypoglycemia. Adjunctive treatment with glucagon-like peptide-1 receptor agonists may reduce glucose variability, hence lower the risk of hypoglycemia and improve awareness. The aim of our study was to investigate the effect of exenatide on awareness of hypoglycemia in patients with type 1 diabetes and IAH. Methods This was a randomized double-blind, placebo-controlled crossover trial. Ten patients with type 1 diabetes and IAH were included [age, 38.5 ± 4.4 years; 40% males; glycated hemoglobin 7.2% ± 0.4% (55.2 ± 4.8 mmol/mol)]. Patients were treated with exenatide 5 µg twice daily (first two weeks), followed by 10 µg twice daily (remaining four weeks) or matching placebo, with a four-week washout period. Patients wore blinded glucose sensors in the final weeks and modified hyperinsulinemic normoglycemic-hypoglycemic glucose clamps (nadir 2.5 mmol/L) were performed at the end of each treatment period. Results Treatment with exenatide caused body weight to decrease compared with placebo (−3.9 ± 0.9 vs 0.6 ± 1.2 kg, P = 0.047). Exenatide did not change mean 24-hour glucose levels (8.3 ± 0.4 vs 8.5 ± 0.3 mmol/L, exenatide vs placebo, P = 0.64), median (interquartile range) percentage of time spent in hypoglycemia [15.5 (4.5, 25.5) vs 7.8 (4.4, 17.1)%, P = 0.11] and frequency of hypoglycemia (15.8 ± 3.7 vs 12.1 ± 3.5, P = 0.19). Symptom scores in response to clamped hypoglycemia were similar between exenatide [median change 1.0 (−1.5, 7.0)] and placebo [4.5 (1.5, 5.8), P = 0.08]. Conclusions Six weeks of treatment with exenatide did not improve awareness of hypoglycemia in patients with type 1 diabetes and IAH.

IntroductionThis study examines the feasibility of conducting diabetes-focused cognitive–behavioral therapy (CBT) via a secure online real-time instant messaging system intervention to support self-management and improve glycemic control in people with type 1 diabetes.Research design and methodsWe used a pre–post uncontrolled intervention design over 12 months. We recruited adults with type 1 diabetes and suboptimal glycemic control (HbA1c ≥69 mmol/mol (DCCT 8.5%) for 12 months) across four hospitals in London. The intervention comprised 10 sessions of diabetes-focused CBT delivered by diabetes specialist nurses. The primary outcomes were number of eligible patients, rates of recruitment and follow-up, number of sessions completed and SD of the main outcome measure, change in HbA1c over 12 months. We measured the feasibility of collecting secondary outcomes, that is, depression measured using Patient Health Questionnaire-9 (PHQ-9), anxiety measured Generalised Anxiety Disorder (GAD) and the Diabetes Distress Scale (DDS).ResultsWe screened 3177 patients, of whom 638 were potentially eligible, from whom 71 (11.1%) were recruited. The mean age was 28.1 (13.1) years, and the mean HbA1c was 84.6 mmol/mol (17.8), DCCT 9.9%. Forty-six (65%) patients had at least 1 session and 29 (41%) completed all sessions. There was a significant reduction in HbA1c over 12 months (mean difference −6.2 (2.3) mmol/mol, DCCT 0.6%, p=0.038). The change scores in PHQ-9, GAD and DDS also improved.ConclusionsIt would be feasible to conduct a full-scale text-based synchronized real-time diabetes-focused CBT as an efficacy randomized controlled trial.
