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...

Sacubitril/valsartan (LCZ696) is indicated for the treatment of heart failure with reduced ejection fraction. Absorption of sacubitril/valsartan and conversion of sacubitril (prodrug) to sacubitrilat (neprilysin inhibitor) was rapid with maximum plasma concentrations of sacubitril, sacubitrilat, and valsartan (angiotensin receptor blocker) reaching within 0.5, 1.5-2.0, and 2.0-3.0 h, respectively. With a two-fold increase in dose, an increase in the area under the plasma concentration-time curve was proportional for sacubitril, ~1...

Purpose. In this study, we investigated the effect of PGC1α activators on mitochondrial fusion, fission, and autophagic quality control in renal tubular cells in a diabetic environment in vivo and in vitro. We also examined whether the upregulation of PGC1α attenuates diabetic tubulopathy by normalizing mitochondrial homeostasis. Methods. HKC8 cells were subjected to high-glucose conditions (30 mM D-glucose). Diabetes was induced with streptozotocin (STZ, 50 mg/kg i.p. for 5 days) in male C57/BL6J mice...

Worldwide, an estimated 200 million people have chronic kidney disease (CKD), whose most common causes include hypertension, arteriosclerosis, and diabetes. About 40% of patients with diabetes develop CKD and intensive blood glucose control through pharmacological intervention can delay CKD progression. Standard therapies for the treatment of type 2 diabetes mellitus include metformin, sulfonylureas, meglitinides, thiazolidinediones, and insulin. While these drugs have an important role in the management of type 2 diabetes, only the thiazolidinedione pioglitazone can be used across the spectrum of CKD (stages 2-5) and without dose adjustment...

Circulating autoantibodies and immune complex deposition are pathological hallmarks of systemic lupus erythematosus (SLE). B cell differentiation into plasma cells (PCs) and some T cell subsets that function as B cell helpers can be therapeutic targets of SLE. Mechanistic target of rapamycin (mTOR) signaling is implicated in the formation of B cells and germinal centers (GCs). We assessed the effect of metformin, which inhibits mTOR, on the development of autoimmunity using Roquin(san/san) mice. Oral administration of metformin inhibited the formation of splenic follicles and inflammation in kidney and liver tissues...

Metformin intoxication with lactic acidosis, a potentially lethal condition, may develop in diabetic patients when the drug dose is inappropriate and/or its clearance is reduced. Diagnosis and therapy may be delayed due to nonspecific symptoms at presentation, with severe anion gap metabolic acidosis and elevated serum creatinine values being the most prominent laboratory findings. Confirmation requires measurement of serum metformin by high-performance liquid chromatography-tandem mass spectrometry, but this technique is available only at specialized institutions and cannot be relied on as a guide to immediate treatment...

BACKGROUND: Vascular calcification (VC) is common in type 2 diabetes, and is associated with cardiovascular complications. Recent preclinical data suggest that metformin inhibits VC both in vitro and in animal models. However, metformin's effects in patients with diabetic VC have not previously been characterized. The present study investigated the association between metformin use and lower-limb arterial calcification in patients with type 2 diabetes and high cardiovascular risk. METHODS: The DIACART cross-sectional cohort study included 198 patients with type 2 diabetes but without severe chronic kidney disease...

Proteinuria (albuminuria) plays a crucial role in the etiology of chronic kidney disease (CKD) via alteration of multiple signaling pathways and cellular process in renal cells. The objectives of this study are to investigate the effects of activation of the energy-sensing molecule AMP-activated kinase (AMPK) in renal cells using metformin on endoplasmic reticulum (ER) stress, AKT, mTOR, epithelial-to-mesenchymal transition (EMT), autophagy, and apoptosis that are thought to mediate renal cell injury during proteinuria, and to dissect the AMPK- and non-AMPK mediated effects of metformin using an in vitro model of albumin-induced renal cell injury...

Clinicians are aware of the risks and benefits of metformin in type 2 diabetes. In geriatric populations lactic acidosis due to diminishing kidney function is an issue. The recent addition of a group of agents to control diabetes through increased glycosuria may increase the risk of dehydration and acidosis. This may happen due to gastrointestinal loss from metformin diarrhea or urine loss from diuretics. A typical example is presented.

Metformin is a first-line oral antidiabetic therapy for patients with type 2 diabetes mellitus. Metformin-associated lactate acidosis (MALA) is a well-known, life-threatening, but rare side effect of metformin therapy. Chronic kidney disease (CKD) patients have a much greater risk of MALA. We report the case of a severe refractory MALA despite hemodialysis (HD) treatment, associated with hypoglycemia, hypothermia, and bradycardia in a neglected and thus untimely-recognized CKD patient with type 2 diabetes mellitus...

Metformin is recommended as the treatment of choice in patients with type 2 diabetes mellitus because of its efficacy, general tolerability and low cost. Recent guidelines have extended the use of metformin to patients with Chronic Kidney Disease (CKD) up to stage III. However, in the recent literature, cases of MALA (metformin-associated lactic acidosis) are increasingly reported. MALA is the most dangerous side effect of the drug, with an incidence rate of 2-9 cases per 100000 person-years of exposure. We report on two patients with accidental metformin overdose, severe lactic acidosis and acute kidney injury...
