The treatment of urinary tract infections in women with diabetes mellitus.
Forty-five women with diabetes mellitus and urinary tract infections have been followed an average of 34 mo on treatment protocols based on localization of infection as determined by the presence or absence of antibody-coated bacteria (ACB). Treatment was usually, but not exclusively, trimethoprim-sulfamethoxazole. Two weeks of oral therapy was equally efficacious to 6 wk of treatment in asymptomatic women with antibody-coated bacteria (ACB)-positive infection in eradicating bacteriuria. Recurrences in all groups were predominantly reinfections with differing serotypes or species of microorganisms. The sustained remission rate (fractional extraction) after initial treatment was similar to other reported groups, but possibly less efficacious with recurrences. Suppressive therapy with trimethoprim-sulfamethoxazole for repeated recurrences effectively prevented infection but provided no posttreatment benefit. A high prevalence of underlying structural genitourinary tract abnormalities, usually detectable on pelvic examination, and which were not direct consequences of diabetes mellitus, were possible contributing factors to recurrent infection in this patient group. Progressive elevation in serum creatinine in seven patients with initial ACB-positive infections appeared to relate more closely to diabetic nephropathy rather than chronic pyelonephritis. ACB-positivity correlated well with elevated serum antibody titers and the presence of underlying anatomic abnormalities, but ACB categorization did not lead to improved therapeutic strategy or outcome and hence was of limited clinical usefulness.
