Abstract
Twelve patients with carpal tunnel syndrome were studied. Clinical and electrophysiological data were obtained and an estimation of vitamin B6 (pyridoxine) status by an assay of erythrocyte aspartate aminotransferase and coenzyme stimulation assay were done. None of the patients was found to have vitamin B6 deficiency. Patients were treated with 150 mg of pyridoxine daily for 3 months. Erythrocyte aspartate aminotransferase increased significantly (p less than 0.001) in all the patients. In 6 patients there were clinical and electrophysiological improvement and erythrocyte aspartate aminotransferase increased more than in the other 6 patients. The data obtained appear to indicate that although vitamin B6 deficiency is not common in carpal tunnel syndrome patients, pyridoxine supplementation can be recommended as adjuvant treatment in those patients undergoing surgery.
