AIMS: Heart failure (HF) is frequent in type 2 diabetes (T2D) and several glucose-lowering medications may increase HF risk. In the SAVOR-TIMI trial, patients on Saxagliptin experienced a 27% higher risk of hospitalisation for HF (HHF). In a retrospective study on 127,555 patients, we showed that DPP-4i therapy was associated with a lower HHF risk than sulphonylurea (SU) therapy. We herein re-analyzed such data to evaluate intraclass differences among DPP-4i and SU. MATERIALS AND METHODS: We included T2D patients initiating DPP-4i or SU alone or in combination with metformin...

AIMS: Metformin is renally excreted and has been associated with the development of lactic acidosis. Although current advice is to omit metformin during illnesses that may increase risk of acute kidney injury (AKI), the evidence supporting this is lacking. We investigated the relationship between AKI, lactate concentrations and the risk of lactic acidosis in those exposed to metformin. METHODS: We undertook a population-based case-control study of lactic acidosis in 1,746 participants with Type 2 diabetes and 846 individuals without diabetes with clinically measured lactates with and without AKI between 1994-2014...

Converging evidence from laboratory models pointed that the widely used antidiabetic drug metformin has direct effects on cancer cells. Thus far, relatively little attention has been addressed to the drug exposures used experimentally relative to those achievable clinically. Here, we demonstrated that metformin loaded on carbon nanotubes under near-infrared (NIR) irradiation led to the remarkably enhancement in response towards cancer cells. The dose of metformin has reduced to only 1/280 of typical doses in monotherapy (35: 10 000-30 000 µM) where the realization of metformin in conventional antidiabetic doses for cancer therapies becomes possible...

CONTEXT: Insulin resistance in polycystic ovary syndrome (PCOS) may increase the risk of reactive hypoglycaemia (RH) and decrease glucagon-like peptide-1 (GLP-1) secretion. The possible effects of treatment with oral contraceptives (OCP) and/or metformin on GLP-1 secretion and risk of RH in PCOS is undetermined. SETTING: Outpatient clinic. PATIENTS AND INTERVENTIONS: Randomized, controlled clinical trial. Ninety women with PCOS were randomized to 12 month treatment with OCP (150 mg desogestrel+30 microgram ethinylestradiol), metformin (2 g/day), or metformin +OCP...

BACKGROUND AND AIMS: The effects of chemotherapeutic agents on the development of colorectal adenomas in patients with previous colorectal cancer (CRC) are not defined. Therefore, we evaluated the potential effect of adjuvant chemotherapy on the incidence of colorectal adenomas in patients with previous CRC. METHODS: We selected patients with low-risk stage II CRC with or without postoperative 5-fluorouracil-based adjuvant chemotherapy to reduce selection bias. Among 1808 patients with stage II CRC who underwent colonoscopic surveillance after curative resection of CRC between 2006 and 2013, 192 patients were retrospectively enrolled in this study after matching for age and sex...

Metformin, one of the most widely prescribed antidiabetic drugs in the world, is being repurposed as a potential drug in cancer treatment. Epidemiological studies suggest that metformin exerts anticancer effects in diabetic patients with pancreatic cancer. However, at typical antidiabetic doses the bioavailability of metformin is presumably too low to exert antitumor effects. Thus, more potent analogs of metformin are needed in order to increase its anticancer efficacy. To this end, a new class of mitochondria-targeted metformin analogs (or mito-metformins) containing a positively-charged lipophilic triphenylphosphonium group was synthesized and tested for their antitumor efficacy in pancreatic cancer cells...

The present study was undertaken to evaluate antidiabetic and antioxidant activities of Cayratia trifolia root extract against streptozotocin induced diabetes in experimental rats to scientifically validate its use against diabetes in some parts of India. Ethanolic extract, showing the highest activity in in vitro experiments, was prepared in saline and administered orally to streptozotocin induced albino Wistar diabetic rats for 21 days. Biochemical parameters liver and muscles glycogen and in vivo antioxidant activity in normal, diabetic control, standard (metformin) and treated animals were determined and compared...

REVIEW
Laurent Azoulay, Samy Suissa
Recent randomized trials have compared the newer antidiabetic agents to treatments involving sulfonylureas, drugs associated with increased cardiovascular risks and mortality in some observational studies with conflicting results. We reviewed the methodology of these observational studies by searching MEDLINE from inception to December 2015 for all studies of the association between sulfonylureas and cardiovascular events or mortality. Each study was appraised with respect to the comparator, the outcome, and study design-related sources of bias...

Anti-VEGF therapy has been proven to be effective in the treatment of pathological angiogenesis. However, therapy resistance often occurs, leading to development of alternative approaches. The present study examines if AMPK negatively regulates ALK1-mediated signaling events and associated angiogenesis. Thus, we treated human umbilical vein endothelial cells with metformin as well as other pharmacological AMPK activators and showed that activation of AMPK inhibited Smad1/5 phosphorylation and tube formation induced by BMP9...

Metformin, the popular anti-diabetic drug was shown to exert multiple biological effects. The most recent metformin gained attention as an agent that mobilizes endogenous progenitor cells and enhances regenerative potential of organisms, for example by promoting neurogenesis. In the present study, we examined the role of metformin on mouse olfactory ensheathing cells (mOECs) derived from animals receiving metformin for eight weeks at a concentration equal to 2.8 mg/day. The mOECs expanded ex vivo were characterized in terms of their cellular phenotype, morphology, proliferative activity, viability and accumulation of oxidative stress factors...

BACKGROUND: Medications that impact insulin sensitivity or cause weight gain may increase heart failure risk. Our aim was to compare heart failure and cardiovascular death outcomes among patients initiating sulfonylureas for diabetes mellitus treatment versus metformin. METHODS AND RESULTS: National Veterans Health Administration databases were linked to Medicare, Medicaid, and National Death Index data. Veterans aged ≥18 years who initiated metformin or sulfonylureas between 2001 and 2011 and whose creatinine was <1...

We demonstrate that model-based unsupervised learning can uniquely discriminate single-cell subpopulations by their gene expression distributions, which in turn allow us to identify specific genes for focused functional studies. This method was applied to MDA-MB-231 breast cancer cells treated with the antidiabetic drug metformin, which is being repurposed for treatment of triple-negative breast cancer. Unsupervised learning identified a cluster of metformin-treated cells characterized by a significant suppression of 230 genes (p-value < 2E-16)...

BACKGROUND: Vildagliptin is a dipeptidyl peptidase-4 inhibitor (DPP4-i) commonly used as a dual oral agent with metformin, thiazolidinediones, or sulfonylurea for type 2 diabetes mellitus (T2DM). The efficacy of dual therapy with vildagliptin and metformin has been established in randomized clinical trials but little evidence exists from observational studies. The aims of the present study were to evaluate the effectiveness of vildagliptin as an add-on therapy to metformin in reducing HbA1c as well as its influences on body weight and blood lipids in a real-life setting...

BACKGROUND: Previous study found that the Chinese Herbal Medicine Jinlida could significantly enhance the hypoglycemic action of metformin compared to metformin alone. However, the advantage of Jinlida has not been clarified yet. We aimed to compare the efficacy of Jinlida in patients with T2DM based on stratification. METHODS: Data were analyzed from a 12-week, randomized, placebo-controlled, double-blind, multicenter study of Jinlida. The efficacy evaluation included HbA1c, FPG and 2hPG levels stratified by baseline HbA1c, sex, age, BMI, and duration of DM diagnosis...
