Oxidative stress plays an important role in the development of diabetic retinopathy. Here, we examined whether α-lipoic acid (α-LA), a natural antioxidant, attenuated retinal injury in diabetic mice. The α-LA was orally administered to control mice or mice with streptozotocin-induced diabetes. We found that α-LA reduced oxidative stress, decreased and increased retinal 4-hydroxy-2-nonenal and glutathione peroxidase, respectively, and inhibited retinal cell death. Concomitantly, α-LA reversed the decreased activation of AMP-activated protein kinase (AMPK) and acetyl-CoA carboxylase, and increased the levels of peroxisome proliferator-activated receptor delta and sirtuin3 in diabetic mouse retinas, similar to results shown after metformin treatment of retinal pigment epithelial cells (RPE) exposed to high glucose...

BACKGROUND Diabetic macular edema (DME) causes serious visual impairments in diabetic patients. The standard treatments of DME are intra-vitreous injections of corticosteroids or anti-vascular endothelial growth factor antibodies and pan-photocoagulation. These treatments are unsatisfactory in their effects and impose considerable physical and economic burdens on the patients. CASE REPORT A 63-year-old woman was diagnosed as type 2 diabetes with retinopathy 7 years ago. Before the initiation of an SGLT2 inhibitor, the dipeptidyl peptidase-4 inhibitor, sitagliptin (50 mg daily), and metformin (250 mg dai- ly) were used for her glycemic control...

The oral anti-diabetic drug metformin has been found to reduce cardiovascular complications independent of glycemic control in diabetic patients. However, its role in diabetic retinal microvascular complications is not clear. This study is to investigate the effects of metformin on retinal vascular endothelium and its possible mechanisms, regarding two major pathogenic features of diabetic retinopathy: angiogenesis and inflammation. In human retinal vascular endothelial cell culture, metformin inhibited various steps of angiogenesis including endothelial cell proliferation, migration, and tube formation in a dose-dependent manner...

Retinal degeneration is an early feature of diabetic retinopathy, the major cause of blindness in the developed world. Here we investigated how the widely used antidiabetic drug metformin reduces retinal injury in diabetic mice. Metformin was orally administered to control mice or mice with streptozotocin-induced diabetes. Western blot analysis showed that levels of O-linked β-N-acetylglucosamine (O-GlcNAc) transferase (OGT) and other related proteins such as carbohydrate-responsive element-binding protein (ChREBP) and thioredoxin-interacting protein (TXNIP) were significantly increased, and nuclear factor kappaB (NF-κB) and poly (ADP-ribose) polymerase (PARP) were activated in the diabetic retinas or retinal pigment epithelial (RPE) cells exposed to high glucose compared to controls...

Diabetes mellitus (DM) is increasing in prevalence nationwide and in South Dakota, with an especially high prevalence in its American Indian population. Screening is not recommended for type 1 DM, but is for type 2 DM and pre-diabetes in certain populations. Fasting glucose, two-hour glucose tolerance test, or hemoglobin A1c are appropriate screening options. Treatment can include diabetic self-management education programs and medications. In addition to glycemic control, other cardiovascular risk factors must be reduced in these patients and specific testing and consultations should be performed to detect complications such as nephropathy or retinopathy...

Metformin is a kind of biguanide hypoglycemic agent that has been widely used in patients with diabetes mellitus. In clinical practice, whether metformin should be stopped before Fundus fluorescein angiography (FFA) remains largely unclear. Some endocrinologists suggest stop metformin before FFA. However, ophthalmologists do not always adopt this opinion in their practice. This situation may lead to disputes between physicians and patients. This article analyzed contrast-induced nephropathy(CIN) and the related contrast agent, as well as the adverse reactions of fluorescein angiography...

Cardiovascular outcome trials of antihyperglycaemic drugs and non-statin LDL-cholesterol-lowering drugs in patients with type 2 diabetes who have, or who are at high risk of, atherosclerotic cardiovascular disease have provided new evidence that has substantially affected the management of cardiovascular risk in these patients. On the basis of proven cardiovascular and renal benefit, the antihyperglycaemic drugs empagliflozin, liraglutide, and semaglutide-the latter being under review for approval by the US Food and Drug Administration and the European Medicines Agency-should be preferentially used as second-line treatments in these patient populations, typically in addition to metformin...

Pathological angiogenesis is the hallmark of diseases such as cancer and retinopathies. Although tissue hypoxia and inflammation are recognized as central drivers of vessel growth, relatively little is known about the process that bridges the two. In a mouse model of ischemic retinopathy, we found that hypoxic regions of the retina showed only modest rates of apoptosis despite severely compromised metabolic supply. Using transcriptomic analysis and inducible loss-of-function genetics, we demonstrated that ischemic retinal cells instead engage the endoplasmic reticulum stress inositol-requiring enzyme 1α (IRE1α) pathway that, through its endoribonuclease activity, induces a state of senescence in which cells adopt a senescence-associated secretory phenotype (SASP)...

Previous studies have shown that metformin, an AMP-activated protein kinase activator widely prescribed for type 2 diabetes, is especially beneficial in cases of diabetic retinopathy (DR) with undetermined mechanisms. Here, we used a streptozotocin-induced diabetes model in mice to study the effects of metformin on the development of DR. We found that 10 weeks after STZ treatment, DR was induced in STZ-treated mice, regardless treatment of metformin. However, metformin alleviated the DR, seemingly through attenuating the retina neovascularization...

Low serum B12 level is a common occurrence in patients with type 2 diabetes (T2DM) treated with metformin. There is lack of evidence concerning blood testing of vitamin B12 and current clinical guidelines make no recommendations on the detection or prevention of vitamin B-12 deficiency during metformin treatment. Our objective was to examine the current practice and clinical determinants of vitamin B12 testing in metformin treated T2DM patients. Data were collected from health maintenance organization patients, and consisted of T2DM patients who were newly prescribed metformin from 2008 to 2013...
