REVIEW
A J Scheen, P Delanaye
Dipeptidyl peptidase-4 inhibitors (DPP-4is) are increasingly being used in the management of type 2 diabetes (T2D). The present review summarizes the current knowledge of the effects of DPP-4is on renal outcomes by analyzing the experimental preclinical data, the effects of DPP-4is on urinary albumin-creatinine ratios (UACRs) and estimated glomerular filtration rates (eGFRs) from observational studies and clinical trials, and renal events (including kidney failure requiring renal replacement therapy) in recent large prospective cardiovascular outcome trials...

Diabetes mellitus is an incurable progressive disease, characterized by elevated blood glucose levels, which lead to the development of micro- and macrovascular complications. Although the etiopathology of the disease remains unclear, it seems to be multifactorial, with an important interaction between genetics and environmental causes. Currently, the genetics of type 2 diabetes (T2D) is poorly understood. The recent advance of the genetic technologies and with a better understanding of genetics, more than 120 distinct genetic loci, with more than 150 variants, have been identified that may be involved in the pathogenesis of T2D...

Introduction: Diabetic nephropathy is associated with specific histological changes. Early detection of poor glomerular and tubular function can be achieved with biomarkers of diabetes. The aim of this study was to evaluate the accuracy of kidney dysfunction biomarkers in type 2 diabetes (T2D). Methods: Patients with T2D were grouped according to their glycated hemoglobin level. Patients' urine and blood samples were taken to measure cystatin C (CysC), neutrophil gelatinase-associated lipocalin, beta-trace protein levels, and the first morning void albumin-to-creatinine ratio...

Background: Inflammatory cytokines have been demonstrated to be involved in developing insulin resistance and type-2 diabetes (T2D). Natural antibodies in the circulation have protective effects on common diseases in humans. The present study was thus designed to test the hypothesis that natural antibodies against inflammatory cytokines could be associated with T2D. Methods: An enzyme-linked immunosorbent assay (ELISA) was developed in-house to detect plasma IgG against peptide antigens derived from interleukin 1α (IL1α), IL1β, IL6, IL8 and tumor necrosis factor-α (TNF-α) in 200 patients with T2D and 220 control subjects...

White women with type II diabetes (T2D) have an estimated 20% increased risk of developing breast cancer. Little is known about associations by breast cancer subtype or among African American (AA) women, who are disproportionately affected by T2D and estrogen receptor negative (ER-) breast cancer. We assessed the relation of T2D to incidence of ER- and ER+ breast cancer in data from the Black Women's Health Study, a prospective cohort of AA women enrolled in 1995 and followed biennially. During 847,934 person-years of follow-up, there were 1,851 incident invasive breast cancers, including 914 ER+ and 468 ER- cases...

Rare fully penetrant mutations in AKT2 are an established cause of monogenic disorders of glucose metabolism. Recently, a novel partial loss-of-function AKT2 coding variant (p.Pro50Thr) was identified that is nearly specific to Finns (frequency 1.1%), with the low-frequency allele associated with an increase in fasting plasma insulin level and risk of type 2 diabetes. The effects of p.Pro50Thr on insulin-stimulated glucose uptake (GU) in the whole body and in different tissues have not previously been investigated...

Statins are the first line of pharmacologic treatment for the management of hypercholesterolemia in patients at risk for atherosclerotic cardiovascular (CV) disease. In recent years, several randomized, controlled trials (RCTs) and observational studies have reported increased risk for new-onset type 2 diabetes mellitus (T2D) with statin treatment, particularly with use of high-intensity statins that reduce low-density lipoprotein cholesterol (LDL-C) by 50% or more. This paper summarizes the data from RCTs and observational studies for statin-associated T2D risk, and puts into perspective this evidence, weighed against the established benefits of statin therapy for CV risk reduction...

With an estimated 422 million affected patients worldwide in 2016, type 2 diabetes (T2D) has reached pandemic proportions and represents a major unmet medical need. T2D is a polygenic disease with a chronic, low-grade inflammatory component. Second-generation transient receptor potential vanilloid-1 (TRPV1) antagonists are potent anti-inflammatory agents with proven clinical safety. In rodent models of T2D, TRPV1 blockade was shown to halt disease progression and improve glucose metabolism. Thus, we propose that TRPV1 antagonists merit further study as novel therapeutic approaches to potentially treat T2D and its comorbidities...

BACKGROUND: Hyperglycemia can result from a loss of pancreatic beta-cells or a decline in their function leading to decreased insulin secretion or may arise from insulin resistance and variable degrees of inadequate insulin secretion resulting in diabetes and related comorbidities. To date several reviews have addressed the issue of diabetes-related male infertility but most have focused on how metabolic syndrome causes the decline in male fertility. However, a comprehensive overview as to how diabetes-induced hyperglycemia impairs male fertility is missing...

Limited medication adherence and persistence are barriers to successful treatment in type 2 diabetes (T2D). We searched MEDLINE, EMBASE, The Cochrane Library, The Register of Controlled Trials, PsychINFO, and CINAHL for observational and interventional studies comparing medication adherence or persistence between two or more glucose lowering medications in people with T2D. Where several studies (n≥5) provided the same comparison a random effects meta-analysis was performed reporting mean difference (MD), odds ratio (OR), or hazard ratio (HR) depending on the pooled study outcomes...

Type 2 diabetes (T2D) is associated with systemic abnormal bone remodeling and bone loss. Meanwhile, abnormal subchondral bone remodeling induces cartilage degradation, resulting in osteoarthritis (OA). Accordingly, we investigated alterations in subchondral bone remodeling, microstructure and strength in knees from T2D patients and their association with cartilage degradation. Tibial plateaus were collected from knee OA patients undergoing total knee arthroplasty and divided into non-diabetic (n=70) and diabetes (n=51) groups...

Cardiovascular disease accounts for the majority of excess deaths seen in patients with Type 2 diabetes (T2D).(1) Thus, in order to improve outcomes in this population, clinicians should focus on therapies that decrease the risk of subsequent cardiovascular events. Over the last two years, randomized controlled clinical trials have identified several agents that decrease cardiovascular events in patients with T2D with or at high risk for cardiovascular disease (CVD) - effects likely unrelated to glucose-lowering, the indication for which they were originally developed...

BACKGROUND/AIMS: Many adolescents with type 2 diabetes (T2D) have rapid deterioration of glycemic control on metformin monotherapy within 2 years of diagnosis. METHODS: Enrollment data from the Pediatric Diabetes Consortium T2D Registry were used to categorize 276 youth with a T2D duration ≥2 years into two groups: (1) participants with HbA1c <7.5% on metformin monotherapy (group 1, n = 75) and (2) participants treated with insulin ± metformin (group 2, n = 201)...

Caloric restriction rapidly reverses type 2 diabetes (T2D), but the mechanism(s) of this reversal are poorly understood. Here we show that 3 days of a very-low-calorie diet (VLCD, one-quarter their typical intake) lowered plasma glucose and insulin concentrations in a rat model of T2D without altering body weight. The lower plasma glucose was associated with a 30% reduction in hepatic glucose production resulting from suppression of both gluconeogenesis from pyruvate carboxylase (VPC), explained by a reduction in hepatic acetyl-CoA content, and net hepatic glycogenolysis...

Alzheimer's disease (AD) is a risk factor for type 2 diabetes and vice versa, and a growing body of evidence indicates that these diseases are connected both at epidemiological, clinical and molecular levels. Recent studies have begun to reveal common pathogenic mechanisms shared by AD and type 2 diabetes. Impaired neuronal insulin signaling and endoplasmic reticulum (ER) stress are present in animal models of AD, similar to observations in peripheral tissue in T2D. These findings shed light into novel diabetes-related mechanisms leading to brain dysfunction in AD...

INTRODUCTION: This 32-week, open-label, randomized, parallel-group, multinational trial aimed to compare the efficacy and safety of stepwise insulin intensification of biphasic insulin aspart 30 (BIAsp 30) relative to stepwise intensification of a basal-bolus regimen in insulin-naïve adults with type 2 diabetes (T2D) who continued pretrial treatment with metformin and sulfonylurea. METHODS: Adults with T2D were randomized into one of two treatment arms for 32 weeks: (1) BIAsp 30 once daily (OD), with the possibility of stepwise treatment intensification up to BIAsp 30 three times daily (TID); (2) insulin glargine OD, with the possibility of stepwise treatment intensification with insulin aspart up to TID...

PURPOSE OF REVIEW: Polycystic ovary syndrome (PCOS) is diagnosed by its characteristic reproductive features. However, PCOS is also associated with metabolic abnormalities, including insulin resistance and β-cell dysfunction. The severity of these abnormalities varies according to the reproductive phenotype, with the so-called NIH or classic phenotype conferring the greatest metabolic risk. The increased risk for type 2 diabetes (T2D) is well established among affected women with the NIH phenotype, but whether PCOS also confers an increased risk for cardiovascular events remains unknown...

Understanding the functional mechanism of SNPs identified in GWAS on complex diseases is currently a challenging task. The studies of expression quantitative trait loci (eQTL) have shown that regulatory variants play a crucial role in the function of associated SNPs. Detecting significant genes (called eGenes) in eQTL studies and analyzing the effect sizes of cis-SNPs can offer important implications on the genetic architecture of associated SNPs and interpretations of the molecular basis of diseases. We applied linear mixed models (LMM) to the gene expression level and constructed likelihood ratio tests (LRT) to test for eGene in the Geuvadis data...
