Risk factors for symptomatic urinary tract infection in women with diabetes
OBJECTIVE - Women with diabetes have urinary tract infections (UTIs) more often than women without diabetes. The aim of the present multicenter study was to evaluate which clinical characteristics are associated with the development of a symptomatic UTI during an 18-month follow-up period. RESEARCH DESIGN AND METHODS - Patients with either type 1 or type 2 diabetes who were between 18 and 75 years of age were included. Follow-up results were available for 589 of the 636 women included in this study. All patients were interviewed, their medical history was noted, and at least one uncontaminated urine culture was collected at the moment of study entry. RESULTS - Of the 589 women, 115 (20%) developed a symptomatic UTI, 96 (83%) of whom were prescribed antimicrobial therapy. A total of 34 women (14%) with type 1 diabetes developed a UTI. The most important risk factor for these women was sexual intercourse during the week before entry into the study (44% without vs. 53% with sexual intercourse, relative risk [RR] = 3.0, P = 0.01). A total of 81 (23%) women with type 2 diabetes developed a UTI. The most important risk factor for these women was the presence of asymptomatic bacteriuria (ASB) at baseline (25% without vs. 42% with ASB, RR = 1.65, P = 0.04). CONCLUSIONS - Risk factors for developing a UTI are the presence of ASB for women with type 2 diabetes and sexual intercourse during the week before entry into the study for women with type 1 diabetes
Consequences of asymptomatic bacteriuria in women with diabetes mellitus
Background: Women with diabetes mellitus (DM) have asymptomatic bacteriuria (ASB) more often than women without DM. It is unknown, however, what the consequences of ASB are in these women. Objectives: To compare women with DM with and without ASB for the development of symptomatic urinary tract infections (UTIs), renal function, and secondary complications of DM during an 18-month follow-up period. Methods: In this multicenter study we monitored women with DM with and without ASB for the development of symptomatic UTIs, renal function, and secondary complications (ie, retinopathy, neuropathy, microvascular, or macrovascular diseases). Data on the first 18-month follow-up period are presented. Results: At least 1 uncontaminated urine culture was available from 636 women (258 with type 1 DM and 378 with type 2 DM). The prevalence af ASB at baseline was 26% (21% for those with type 1 DM and 29% for those with type 2 DM). Follow-up results were available for 589 (93%) of the 636 women. Of these 589 women, 115 (20%) (14%) with type 1 DM and 23% with type 2 DM) developed a symptomatic UTI. Women with type 2 DM and ASB at baseline had an increased risk of developing a UTI during the 18-month follow-up (19% without ASB vs 34% with ASB, P = .006). In contrast, there was no difference in the incidence of symptomatic UTI between women with type 1 DM and ASB and those without ASB (12% with ASB vs 15% without ASB). However, women with type 1 DM and ASB had a tendency to have a faster decline in renal function than those without ASB (relative increase in serum creatine level 4.6% vs 1.5%. P=0.2). Conclusion: Women with type 2 DM and ASB have an increased risk of developing a symptomatic UTI than those without ASB
