Clinical and Electromyographic Characteristics B12 Deficient Polyneuropathy

Abstract

The paper presents a clinical and electromyographic characteristics of 27 patients with polyneuropathy due to vitamin B12 deficiency (average of 109,9 ± 9,9 pg / ml). The results of the analysis of the different variants of the disease and the correlation analysis conducted clinical, laboratory and neurophysiological parameters. The defeat of the peripheral nervous system, combined with hematological symptoms of vitamin B12 deficiency in only 5 patients (18.5%) was the predominant form of polyneuropathy with a primary lesion of sensory fibers (15; 55.6%), but 44.4% (12) cases along with touch, amazed and motor fibers with appropriate clinic. Neuropathic pain was not typical. Serum levels of vitamin B12 has an inverse correlation with age. In addition, the ratio shows the correlation of clinical and neurophysiological parameters characterizing features of the disease.
