Summary of "Preventive role of metformin on peripheral neuropathy induced by diabetes."

Metformin is the first line drug in the treatment of type 2 diabetes, however, little is known about its therapeutic potential to prevent or delay damage to the peripheral nerve. Thus, the aim of this study was to investigate whether metformin is able to attenuate the neuroinflammatory response in sciatic nerve of insulin-dependent diabetic mice. Swiss Webster mice were divided into four groups: Control, Diabetic (STZ), Diabetic +100 mg/kg/day of metformin (STZ + M100) and Diabetic +200 mg/kg/day of metformin. Diabetes was induced by streptozotocin (90 mg/kg, i.p.). Only animals with glycemia ≥270 mg/dl were considered diabetics. Metformin prevented atrophy of myelinated axons, and reduced expression of inflammatory mediators (interleukin-1β, inducible nitric oxide synthase and nitric oxide). However, treatment with 200 mg of metformin was more effective in increasing neurotrophic (myelin basic protein and neural growth factor), angiogenic (vascular endothelial growth factor) and anti-inflammatory (inhibitor kappa B-alpha and interleukin 10) factors. Thus, metformin treatment, especially at the dose of 200 mg, protected the nerve from damages related to chronic hyperglycemia.

Associations between metformin use and vitamin B12 level, anemia and neuropathy in patients with diabetes: a meta-analysis.

Metformin is the first line therapy for patients with diabetes. However, it may lower vitamin B12 (B12) level which could have hematological or neurological implications. The current study aimed to pe...

Medical and Biotech [MESH] Definitions

Peripheral, autonomic, and cranial nerve disorders that are associated with DIABETES MELLITUS. These conditions usually result from diabetic microvascular injury involving small blood vessels that supply nerves (VASA NERVORUM). Relatively common conditions which may be associated with diabetic neuropathy include third nerve palsy (see OCULOMOTOR NERVE DISEASES); MONONEUROPATHY; mononeuropathy multiplex; diabetic amyotrophy; a painful POLYNEUROPATHY; autonomic neuropathy; and thoracoabdominal neuropathy. (From Adams et al., Principles of Neurology, 6th ed, p1325)

A biguanide hypoglycemic agent used in the treatment of non-insulin-dependent diabetes mellitus not responding to dietary modification. Metformin improves glycemic control by improving insulin sensitivity and decreasing intestinal absorption of glucose. (From Martindale, The Extra Pharmacopoeia, 30th ed, p289)

A pharmaceutical preparation of sitagliptin phosphate and metformin hydrochloride that is used in the treatment of TYPE 2 DIABETES.

Disorder of the peripheral nerves that primarily impair small nerve fibers. The affected small nerve fibers include myelinated A-delta fibers (see A FIBERS) and unmyelinated C FIBERS. Because these small fibers innervate skin and help control autonomic function, their neuropathy presents with neuropathic pain, reduced thermal and pain sensitivity, and autonomic dysfunction (e.g. abnormal sweating or facial flushing). Small fiber neuropathy can be idiopathic or associated with underlying diseases (e.g., AMYLOIDOSIS; DIABETES MELLITUS; SARCOIDOSIS; or VASCULITIS).

Ischemic injury to the OPTIC NERVE which usually affects the OPTIC DISK (optic neuropathy, anterior ischemic) and less frequently the retrobulbar portion of the nerve (optic neuropathy, posterior ischemic). The injury results from occlusion of arterial blood supply which may result from TEMPORAL ARTERITIS; ATHEROSCLEROSIS; COLLAGEN DISEASES; EMBOLISM; DIABETES MELLITUS; and other conditions. The disease primarily occurs in the sixth decade or later and presents with the sudden onset of painless and usually severe monocular visual loss. Anterior ischemic optic neuropathy also features optic disk edema with microhemorrhages. The optic disk appears normal in posterior ischemic optic neuropathy.
