Screening, diagnosis and management of diabetic sensorimotor polyneuropathy in clinical practice: International expert consensus recommendations.

Diabetic sensorimotor polyneuropathy (DSPN) affects around one third of people with diabetes and accounts for considerable morbidity, increased risk of mortality, reduced quality of life, and increased health care costs resulting particularly from neuropathic pain and foot ulcers. Painful DSPN is encountered in 13-26% of diabetes patients, while up to 50% of patients with DSPN may be asymptomatic. Unfortunately, DSPN still remains inadequately diagnosed and treated.

Skin autofluorescence: Correlation with measures of diabetic sensorimotor neuropathy.

Objective: Advanced glycation end products (AGE) contribute to the development of diabetes complications. Their accumulation in skin can be non-invasively assessed by measurement of skin autofluorescence (SAF). Our study investigated whether SAF correlates with measures of diabetic peripheral neuropathy (DPN).

Advances in the management of diabetic neuropathy.

The authors review current advances in the therapy of diabetic neuropathy. The role of glycemic control and management of cardiovascular risk factors in the prevention and treatment of neuropathic complications are discussed. As further options of pathogenetically oriented treatment, recent knowledge on benfotiamine and alpha-lipoic acid is comprehensively reviewed.

A randomised, active- and placebo-controlled, three-period crossover trial to investigate short-term effects of the dipeptidyl peptidase-4 inhibitor linagliptin on macro- and microvascular endothelial function in type 2 diabetes.

Background: Studies of dipeptidyl peptidase (DPP)-4 inhibitors report heterogeneous effects on endothelial function in patients with type 2 diabetes (T2D). This study assessed the effects of the DPP-4 inhibitor linagliptin versus the sulphonylurea glimepiride and placebo on measures of macro- and microvascular endothelial function in patients with T2D who represented a primary cardiovascular disease prevention population.

Methods: This crossover study randomised T2D patients (n = 42) with glycated haemoglobin (HbA1c) ≤7.

Aleglitazar, a dual peroxisome proliferator-activated receptor-α/γ agonist, improves insulin sensitivity, glucose control and lipid levels in people with type 2 diabetes: findings from a randomized, double-blind trial.

The present single-centre, randomized, double-blind, placebo-controlled phase II study investigated the effect of the balanced dual peroxisome proliferator-activated receptor-α/γ agonist aleglitazar on whole-body and liver insulin sensitivity, β-cell function and other components of cardiometabolic syndrome after 16 weeks of treatment in patients with type 2 diabetes inadequately controlled with metformin monotherapy who received once-daily 150 µg aleglitazar or matching placebo as add-on therapy to metformin. Baseline and 16-week assessments included a two-step hyperinsulinaemic-euglycaemic clamp, followed by a hyperglycaemic clamp, as well as evaluation of glycated haemoglobin (HbA1c), lipids and safety variables. The primary endpoint was change in whole-body insulin sensitivity (M-value) from baseline compared with placebo, derived from the second clamp step.
