Background: Glucagon-like peptide 1 agonists differ in chemical structure, duration of action and in their effects on clinical outcomes. The cardiovascular effects of once-weekly albiglutide in type 2 diabetes are unknown. Methods: We randomly assigned patients with type 2 diabetes and cardiovascular disease to the addition of once-weekly subcutaneous injection of albiglutide (30 mg to 50 mg) or matching placebo to standard care. We hypothesized that albiglutide would be noninferior to placebo for the primary outcome of first occurrence of cardiovascular death, myocardial infarction, or stroke. If noninferiority was confirmed by an upper limit of the 95% confidence interval for the hazard ratio of less than 1.30, closed-testing for superiority was prespecified. Findings: Overall, 9463 participants were followed for a median of 1.6 years. The primary composite outcome occurred in 338 of 4731 patients (7.1%; 4.6 events per 100 person-years) in the albiglutide group and in 428 of 4732 patients (9.0%; 5.9 events per 100 person-years) in the placebo group (hazard ratio, 0.78; 95% confidence interval [CI ], 0.68 to 0.90), indicating that albiglutide, was superior to placebo (P<0.0001 for noninferiority, P=0.0006 for superiority). The incidence of acute pancreatitis (albiglutide 10 patients and placebo 7 patients), pancreatic cancer (6 and 5), medullary thyroid carcinoma (0 and 0), and other serious adverse events did not differ significantly between the two groups. Interpretation: In patients with type 2 diabetes and cardiovascular disease, albiglutide was superior to placebo with respect to major adverse cardiovascular events. (Funded by GlaxoSmithKline; Harmony Outcomes ClinicalTrials.gov number, NCT02465515.) noninferiority; P = 0.06 for superiority). There seems to be variation in the results of existing trials with GLP-1 receptor agonists, which if correct, might reflect drug structure or duration of action, patients studied, duration of follow-up or other factors.
The 1858T variant of the protein tyrosine phosphatase gene, PTPN22, is associated with an increased risk of several autoimmune diseases. The aim of this study has been to investigate the possible association of 1858C-->T PTPN22 polymorphism and type 1 diabetes (T1D) in Caucasians from Ukraine. Overall, the distribution of 1858 PTPN22 genotypes differed significantly between the T1D patient group (n = 296) and the control group (n = 242) (P = 0.0036). When both groups were classified according to sex, the TT genotype and T allele showed a statistically significant higher frequency in T1D female patients (5.9 and 22.8%, respectively) in comparison with the female controls (0 and 11.9%) (P = 0.008 for both analyses). The patients with the TT genotype were significantly younger at the onset of T1D compared with those with genotypes TC and CC (P = 0.035 and 0.019, respectively). In our Ukrainian Caucasian cohort, we confirmed the association between T1D and the PTPN22,1858T allele.
OBJECTIVE Finerenone significantly improved cardiorenal outcomes in patients with chronic kidney disease (CKD) and type 2 diabetes (T2D) in the Finerenone in Reducing Kidney Failure and Disease Progression in Diabetic Kidney Disease trial. We explored whether baseline HbA1c level and insulin treatment influenced outcomes. RESEARCH DESIGN AND METHODS Patients with T2D, urine albumin-to-creatinine ratio (UACR) of 30–5,000 mg/g, estimated glomerular filtration rate (eGFR) of 25 to <75 mL/min/1.73 m2, and treated with optimized renin–angiotensin system blockade were randomly assigned to receive finerenone or placebo. Efficacy outcomes included kidney (kidney failure, sustained decrease ≥40% in eGFR from baseline, or renal death) and cardiovascular (cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure) composite endpoints. Patients were analyzed by baseline insulin use and by baseline HbA1c <7.5% (58 mmol/mol) or ≥7.5%. RESULTS Of 5,674 patients, 3,637 (64.1%) received insulin at baseline. Overall, 5,663 patients were included in the analysis for HbA1c; 2,794 (49.3%) had baseline HbA1c <7.5% (58 mmol/mol). Finerenone significantly reduced risk of the kidney composite outcome independent of baseline HbA1c level and insulin use (Pinteraction = 0.41 and 0.56, respectively). Cardiovascular composite outcome incidence was reduced with finerenone irrespective of baseline HbA1c level and insulin use (Pinteraction = 0.70 and 0.33, respectively). Although baseline HbA1c level did not affect kidney event risk, cardiovascular risk increased with higher HbA1c level. UACR reduction was consistent across subgroups. Adverse events were similar between groups regardless of baseline HbA1c level and insulin use; few finerenone-treated patients discontinued treatment because of hyperkalemia. CONCLUSIONS Finerenone reduces kidney and cardiovascular outcome risk in patients with CKD and T2D, and risks appear consistent irrespective of HbA1c levels or insulin use.
Summary. Mitral valve prolapse is a significant cardiovascular risk factor in young adults. Its combination with type 1 diabetes mellitus can influence the nature and development of the disease. Objective – a comparative analysis of free and peptide-bound oxyproline levels and basic echocardiographic parameters (ECP) in patients with mitral valve prolapse, type 1 diabetes and their combination. Materials and methods – 93 people aged 19–33 years were examined, including 24 people with mitral valve prolapse without concomitant pathology; 33 patients with mitral valve prolapse and type 1 diabetes; 36 patients with type 1 diabetes without mitral valve prolapse. Results. The level of free and peptide-bound oxyproline in blood serum and their ratio were assessed as a marker of collagen metabolism. The levels of free oxyproline were significantly higher only for the group of MVP patients with type 1 diabetes (p < 0.05) compared to the control group. Severity of destructive processes was demonstrated by a high level of peptide-bound oxyproline, both in combined pathology compared with control group, and compared with groups of patients with monomorbid diabetes and MVP (p < 0.05). In patients with mitral valve prolapse and type 1 diabetes for more than 10 years in anamnesis were found significant differences in the echocardiography parameters (ventricular septum thickness, posterior wall of the left ventricle thickness) compared with the subgroup of patients with less than 10 years of type 1 diabetes in anamnesis and the group with isolated mitral valve prolapse. Conclusions. The data obtained indicate an aggravation in collagen metabolism disorders in patients with mitral valve prolapse depending on the duration of type 1 diabetes, and demonstrate the effect of carbohydrate metabolism disorders on the risk of developing connective tissue degradation of the heart valve apparatus.
