Vitamin B6 levels in rheumatoid arthritis: effect of treatment

Abstract

Patients with rheumatoid arthritis were found to have low plasma pyridoxal phosphate. Treatment with 50-150 mg/day of pyridoxine hydrochloride for 3 months caused a rise in pyridoxal phosphate in most cases to more than 3 times pretreatment levels. There was, however, no improvement in the clinical aspects of rheumatoid arthritis.
