[Show abstract][Hide abstract] ABSTRACT: Urinary tract infection occurs with increased frequency and severity in patients with diabetes mellitus. General host factors enhancing risk for urinary tract infection in diabetics include age, metabolic control, and long term complications, primarily diabetic nephropathy and cystopathy. Alterations in the innate immune system have been described and may also contribute. Treatment of asymptomatic bacteriuria in diabetic patients is not indicated. Early diagnosis and prompt intervention is recommended to limit morbidity of symptomatic infection. Clinical studies comparing management of urinary tract infection in persons with diabetes compared to those without as well as diabetic patients with good or poor glucose control will be necessary to improve care of urinary infection in persons with diabetes mellitus.
