The association of bacteriuria and reduced serum pyridoxal concentrations in patients with diabetes mellitus.
Of 1017 patients admitted to the Royal Perth Hospital Diabetic Survey 142 were found to have significant bacteriuria. In these bacteriuric patients serum pyridoxal concentrations were significantly reduced (P = less than 0.001) when compared with 142 diabetic patients matched for age (+/- 5 years) and sex but without infection of the urinary tract. Measurements were repeated up to 6 mth after antibacterial treatment and serum pyridoxal concentrations were still low. Pyridoxal has a role in immunological competence, and it is possible that the increased incidence of urinary tract infection in patients with diabetes reflects impaired immunological competence due to pyridoxal deficiency.
