RESUMEN
Dipeptidyl peptidase-4 (DPP-4) inhibitors are a class of glucose-lowering agent for type 2 diabetes (T2D) that are commonly used in clinical practice. With the recent disclosure of data from the CARMELINA cardiovascular outcomes trial (CVOT), which investigated linagliptin, CV and renal outcomes data are now available for four agents in the DPP-4 inhibitor class that are approved in most markets. To consider how the CARMELINA study may be interpreted, and the relevance for our clinical practice, we convened as an expert group of diabetes specialists from the Central and Eastern Europe region to discuss the new disclosures. Our discussions revealed a general confidence in safety across the class that is further supported by CARMELINA. However, we also concluded that there are important differences in the available evidence level between agents in the setting of heart failure and data on renal outcomes. Here, we noted the clinical relevance to our practice of the study population in CARMELINA, which is unique among CVOTs in including a majority of patients with chronic kidney disease (CKD). Given the risk for future development of renal impairment that is associated with T2D even in patients without current overt CKD, we believe that the CARMELINA study provides important new insights that are clinically relevant for a broad range of patients. Finally, we discuss how these insights can be integrated into the approach to the pharmacotherapeutic management of hyperglycaemia that is recommended in newly updated guidelines.

OBJECTIVE: Self-adjustment of insulin dose is commonly practiced in Western patients with type 2 diabetes but is usually not performed in Asian patients. This multinational, 24-week, randomized study compared patient-led with physician-led titration of once-daily insulin glargine in Asian patients with uncontrolled type 2 diabetes who were on 2 oral glucose-lowering agents. METHODS: Patient-led (n = 275) or physician-led (n = 277) subjects followed the same dose-titration algorithm guided by self-monitored fasting blood glucose (FBG; target, 110 mg/dL [6.1 mmol/L]). The primary endpoint was change in mean glycated hemoglobin (HbA1c) at week 24 in the patient-led versus physician-led titration groups. RESULTS: Patient-led titration resulted in a significantly higher drop in HbA1c value at 24 weeks when compared with physician-led titration (-1.40% vs. -1.25%; mean difference, -0.15; 95% confidence interval, -0.29 to 0.00; P = .043). Mean decrease in FBG was greatest in the patient-led group (-2.85 mmol/L vs. -2.48 mmol/L; P = .001). The improvements in HbA1c and FBG were consistent across countries, with similar improvements in treatment satisfaction in both groups. Mean daily insulin dose was higher in the patient-led group (28.9 units vs. 22.2 units; P<.001). Target HbA1c of <7.0% without severe hypoglycemia was achieved in 40.0% and 32.9% in the patient-led and physician-led groups, respectively (P = .086). Severe hypoglycemia was not different in the 2 groups (0.7%), with an increase in nocturnal and symptomatic hypoglycemia in the patient-led arm. CONCLUSION: Patient-led insulin glargine titration achieved near-target blood glucose levels in Asian patients with uncontrolled type 2 diabetes who were on 2 oral glucose-lowering drugs, demonstrating that Asian patients can self-uptitrate insulin dose effectively when guided.

UNLABELLED: We examined the role of endothelial dysfunction in the development and progression of cardiorenal syndrome in 93 patients with type 1 diabetes mellitus. PATIENTS: According to the stage of renal insufficiency all patients were divided into equal groups: those with normal albumin excretion rate, with microalbuminuria, with proteinuria, and with chronic renal failure. We analyzed endothelial flow-mediated dilation of the brachial artery, levels of endothelin-1, von Willerbrand factor, C-reactive protein, renal:albumin and protein excretion rates, glomerular filtration rate (GFR), and cardiovascular (ECG, echocardiography, blood pressure monitoring) functions. RESULTS: There were negative correlations between the GFR, BP level and endothelial dysfunction markers. At the same time GFR correlated positively with the coefficient of sensitivity of endothelium to shear stress. There were also positive correlations between BP, permeability of glomerular filter and endothelial dysfunction markers and negative correlation with the coefficient of sensitivity of endothelium to shear stress and GFR. Left ventricle mass correlated with markers of endothelial dysfunction and stage of renal disease. Patients with chronic renal failure had negative correlations between LVM and GFR, ILVM and GFR and a positive correlation between ejection fraction and GFR. CONCLUSIONS: There is a close relationship between endothelial dysfunction and development and progression of renal and cardiovascular pathology in patients with type 1 diabetes mellitus.
