title: Pathogenesis and management of bacterial urinary tract infections in adult patients with diabetes mellitus.
abstract: Urinary tract infections (UTIs) are more common and tend to have a more complicated course in patients with diabetes mellitus (DM). The mechanisms, which potentially contribute to the increased prevalence of both asymptomatic and symptomatic bacteriuriai in these patients are defects in the local urinary cytokine secretions and an increased adherence of the microorganisms to the uroepithelial cells. The need for treatment of asymptomatic bacteriuria remains controversial. No evidence is available on the optimal treatment of acute cystitis and pyelonephritis in patients with DM. Because of the frequent (asymptomatic) upper tract involvement and the possible serious complications, many experts recommend a 7-14-day oral antimicrobial regimen for bacterial cystitis in these patients, with an antimicrobial agent that achieves high levels both in the urine and in urinary tract tissues. Current data suggest that shorter regimens will lead to failure also in uncomplicated UTI in women. The recommended treatment of acute pyelonephritis does not differ from that in nondiabetic patients. Clinical trials specifically dealing with the treatment of UTIs in diabetic patients, comparing the optimal duration and choice of antimicrobial agent, are needed. Besides that, new approaches to preventive strategies must prove their value in this specific patient group.
