ReviewSodium-glucose co-transporter-2 inhibitors and diabetic ketoacidosis: An updated review of the literature.
Sodium-glucose cotransporter-2 inhibitors (SGLT2is) are increasingly used for the treatment of type 2 diabetes (T2D) and can improve glucose control also in type 1 diabetes (T1D). In May 2015, regulatory agencies issued a warning that SGLT2is may cause diabetic ketoacidosis (DKA). We report details on 2 new cases of SGLT2i-associated DKA and review the literature for similar cases within randomized controlled trials (RCTs), cohort studies and single reports. ⋯ DKA is a rare adverse event during SGLT2i therapy. Predisposing and precipitating factors are still incompletely understood, although a minority of cases lacked typical DKA triggers. More narrative case series and cohort studies are needed to better understand the true risk and the spectrum of this adverse event.

Design and baseline characteristics of participants in the Researching cardiovascular Events with a Weekly INcretin in Diabetes (REWIND) trial on the cardiovascular effects of dulaglutide.
The aim was to determine the effects of dulaglutide, a synthetic once-weekly, injectable human glucagon-like peptide 1 analogue that lowers blood glucose, body weight, appetite and blood pressure, on cardiovascular outcomes. People with type 2 diabetes, aged ≥50 years, with glycated haemoglobin (HbA1c) ≤9.5%, and either a previous cardiovascular event, evidence of cardiovascular disease or ≥2 cardiovascular risk factors were randomly allocated to a weekly subcutaneous injection of either dulaglutide (1.5 mg) or placebo and followed within the ongoing Researching cardiovascular Events with a Weekly INcretin in Diabetes (REWIND) trial every 3 to 6 months. The primary cardiovascular outcome is the first occurrence of the composite of cardiovascular death or non-fatal myocardial infarction or non-fatal stroke. ⋯ Recruitment of 9901 participants (mean age 66 years, 46% women) occurred in 370 sites located in 24 countries over a period of 2 years. The mean duration of diabetes was 10 years, mean baseline HbA1c was 7.3%, and 31% had prior cardiovascular disease. The REWIND trial's international scope, high proportion of women, high proportion of people without prior cardiovascular disease and inclusion of participants whose mean baseline HbA1c was 7.3% suggests that its cardiovascular and safety findings will be directly relevant to the typical middle-aged patient seen in general practice throughout the world.

Does SGLT2 inhibition with dapagliflozin overcome individual therapy resistance to RAAS inhibition?
Individual patients show a large variation in their response to renin-angiotensin-aldosteron system (RAAS) inhibition (RAASi), both in surrogates such as albuminuria and in hard renal outcomes. Sodium-glucose co-transporter 2 inhibitors (SGLT2) have been shown to lower albuminuria and to confer cardiovascular and, possibly, renal protection. To establish whether individual therapy resistance to RAASi can be overcome by adding an SGLT2 inhibitor, we assessed individual albuminuria responses in patients exposed to both RAASi and the SGLT2 inhibitor dapagliflozin. ⋯ Interestingly, the albuminuria response to RAASi significantly correlated with the response to dapagliflozin (Pearson correlation coefficient, 0.635 [95% CI, 0.328-0.821]; P < .001), indicating that patients who did not respond to RAASi also did not respond to dapagliflozin. We concluded that individual therapy resistance to RAASi cannot be overcome with the addition of a completely different class of drugs, SGLT2 inhibitors. These data suggest that the individual drug response is an intrinsic individual characteristic, possibly unrelated to the type of intervention, unless the mode of action of dapagliflozin on albuminuria is through the RAAS.

Comparative StudyA novel GIP analogue, ZP4165, enhances glucagon-like peptide-1-induced body weight loss and improves glycaemic control in rodents.
To investigate the effects of the novel glucose-dependent insulinotropic polypeptide (GIP) analogue, ZP4165, on body weight and glycaemic control in rodents, and to investigate if ZP4165 modulates the anti-obesity and anti-hyperglycaemic effects of a glucagon-like peptide-1 (GLP-1) agonist (liraglutide). ⋯ ZP4165 potentiated the anti-obesity effect of a GLP-1 agonist in obese mice and improved glycaemic control in diabetic mice. These studies support further investigation of dual-incretin therapy as a more effective treatment option than mono GLP-1 medication for type 2 diabetes mellitus and obesity.

Randomized Controlled Trial Multicenter Study Comparative StudyInsulin degludec/liraglutide (IDegLira) was effective across a range of dysglycaemia and body mass index categories in the DUAL V randomized trial.
This study assessed the efficacy of insulin degludec/liraglutide (IDegLira) vs insulin glargine U100 (IGlar) across categories of baseline glycated haemoglobin (HbA1c; ≤7.5%, >7.5% to ≤8.5% and >8.5%), body mass index (BMI; <30, ≥30 to <35 and ≥35 kg/m2 ) and fasting plasma glucose (FPG; <7.2 and ≥7.2 mmol/L) in patients with type 2 diabetes (T2D) uncontrolled on basal insulin, using post hoc analyses of the DUAL V 26-week trial. With IDegLira, mean HbA1c was reduced across all baseline HbA1c (1.0%-2.5%), FPG (1.5%-1.9%) and BMI categories (1.8%-1.9%), with significantly greater reductions compared with IGlar U100. ⋯ More patients achieved HbA1c <7% with IDegLira than IGlar U100 across all HbA1c (59%-87% vs 31%-66%), FPG (71%-74% vs 40%-51%) and BMI categories (71%-73% vs 40%-54%). IDegLira improved glycaemic control and induced weight loss in patients with T2D previously uncontrolled on basal insulin, across the categories of baseline HbA1c, FPG or BMI that were tested.
