Клинические аспекты применения витаминов группы В

Abstract

Polyneuropathy is a common disorder of the peripheral nervous system. Diabetic neuropathy is the most common and most studied variant of polyneuropathies. The duration of carbohydrate metabolism disorders and inadequate glycemic control are risk factors for nervous system damage in diabetes. Distal neuropathy is a common type of neuropathy associated with diabetes. Interconnecting pathological mechanisms initiated by high blood glucose result in the damage of peripheral nerve fibers. Clinical presentations of distal neuropathy depend on the damage of proximal or distal and sensory or motor nerve fibers and the involvement of the vegetative nervous system. Medications improving metabolic processes in nerve fibers and reducing the severity of peripheral nerve damage are beneficial in addressing the harmful effects of hyperglycemia. Neurometabolic therapy includes thiamine, pyridoxine, and cyanocobalamin (B vitamins) which provide neurotropic effects. B vitamins acting as co-factors in many enzymatic reactions significantly affect the normal functioning of nerve fibers. B vitamins are effective and safe agents used to treat peripheral nervous system diseases for many years. This paper discusses the potential use of B vitamins for diabetic neuropathy and the COVID-19 treatment and rehabilitation.
