Aliskiren may have renoprotective effects that are independent of its blood-pressure-lowering effect in patients with hypertension, type 2 diabetes, and nephropathy who are receiving the recommended renoprotective treatment. (ClinicalTrials.gov number, NCT00097955 [ClinicalTrials.gov].).

OBJECTIVE -Conflicting evidence of a decline in incidence of microvascular complications in type 1 diabetes during the last decades has been reported. To assess recent trends in the cumulative incidence of diabetic microangiopathy in type 1 diabetes, we analyzed data from long-term prospective observational studies lasting Ն20 years. RESULTS -In patients followed for Ն20 years, the cumulative incidence (95% CI) of diabetic nephropathy after 20 years of diabetes (urinary albumin excretion Ͼ300 mg/24 h) was reduced in patients with more recent diabetes onset (groups A-D): 31.1% (22.5-39.7) vs. 28.4% (19.8 -37.0) vs. 18.9% (10.9 -26.9) vs. 13.7% (6.2-21.2) (P ϭ 0.015). Similarly, the cumulative incidence of proliferative retinopathy was as follows: 31.2% (22.2-39.8) vs. 30.3% (22.2-38.4) vs. 19.3% (11.2-27.4) vs. 12.5% (5.2-19.8) (P Ͻ 0.01). In the latter groups, antihypertensive treatment was started earlier, blood pressure and HbA 1c were lower, and fewer patients smoked. RESEARCH DESIGN AND METHODSCONCLUSIONS -Our study demonstrates a decrease in the cumulative incidence of diabetic microangiopathy in type 1 diabetes over the past 35 years. Improved glycemic control, lower blood pressure (in part due to early aggressive antihypertensive treatment), and reduced prevalence of smoking rates were associated with the improved prognosis.

AimsTo compare the sodium‐glucose‐cotransporter‐2 (SGLT‐2) inhibitor dapagliflozin with dipeptidyl peptidase‐4 (DPP‐4) inhibitors with regard to risk associations with major adverse cardiovascular (CV) events (MACE; non‐fatal myocardial infarction, non‐fatal stroke or cardiovascular mortality), hospitalization for heart failure (HHF), atrial fibrillation and severe hypoglycaemia in patients with type 2 diabetes (T2D) in a real‐world setting.MethodsAll patients with T2D prescribed glucose‐lowering drugs (GLDs) during 2012 to 2015 were identified in nationwide registries in Denmark, Norway and Sweden. Patients were divided into two groups: new users of dapagliflozin and new users of DPP‐4 inhibitors, matched 1:3 by propensity score, calculated by patient characteristics, comorbidities and drug treatment. Cox survival models were used to estimate hazard ratio (HR) per country separately, and a weighted average was calculated.ResultsAfter matching, a total of 40 908 patients with T2D were identified as new users of dapagliflozin (n = 10 227) or a DPP‐4 inhibitor (n = 30 681). The groups were well balanced at baseline; their mean age was 61 years and 23% had CV disease. The mean follow‐up time was 0.95 years, with a total of 38 760 patient‐years. Dapagliflozin was associated with a lower risk of MACE, HHF and all‐cause mortality compared with DPP‐4 inhibitors: HRs 0.79 (95% confidence interval [CI] 0.67‐0.94), 0.62 (95% CI 0.50‐0.77), and 0.59 (95% CI 0.49‐0.72), respectively. Numerically lower, but non‐significant HRs were observed for myocardial infarction (0.91 [95% CI 0.72‐1.16]), stroke (0.79 [95% CI 0.61‐1.03]) and CV mortality (0.76 [95% CI 0.53‐1.08]) Neutral associations with atrial fibrillation and severe hypoglycaemia were observed.ConclusionsDapagliflozin was associated with lower risks of CV events and all‐cause mortality compared with DPP‐4 inhibitors in a real‐world clinical setting and a broad T2D population.
