The relationship of vitamin-B6 status to median nerve function and carpal tunnel syndrome was examined in active industrial workers. In order to address potential weaknesses in previously reported studies, this study incorporated a large number of randomly selected subjects, standardized electrophysiologic assessment of nerve function, and multiple complementary measurements of vitamin-B6 status. The study group was composed of 125 randomly selected active workers (67% females) from two industrial facilities. The workers completed a self administered symptoms questionnaire and underwent electrodiagnostic testing of the median and ulnar sensory nerves. Vitamin-B6 status was evaluated using the erythrocyte glutamic-pyruvic-transaminase (EGPT) assay and quantification of plasma pyridoxal-5'-phosphate. Vitamin-B6 status was normal in most subjects; an abnormal EGPT index was found in only ten workers. Median mononeuropathy was detected in 31 participants. Vitamin-B6 status was not related to self reported symptoms associated with carpal tunnel syndrome or electrophysiologically determined median or ulnar nerve function. The authors conclude that the findings do not support a relationship between carpal tunnel syndrome among active industrial workers and vitamin-B6 status; the routine prescription of vitamin-B6 to patients with carpal tunnel syndrome should therefore be reconsidered.
