1700. What Is Specific With Bacterial Escherichia Coli Urinary Tract Infection

Background Bacterial urinary tract infections continue to be a major health problem, responsible for a significant morbidity and mortality. Its prognosis is more severe than non-bacterial forms. The aim of this work was to study the clinical and evolutionary features of bacterial urinary tract infections caused by Escherichia coli (E.coli). Methods We conducted a retrospective study including all patients hospitalized in infectious diseases department for urinary tract infection (UTI) caused by E.coli between 2010 and 2017. Results During the study period, we enrolled 613 cases of UTI caused by E.coli, among whom 75 cases (12.2%) were bacterial. There were 47 females (62.7%). The mean age was 59 ±17 years. Thirty-three patients were aged ≥ 65 years (44%). Diabetes was noted in 38 cases (50.7%) and renal lithiasis in 14 cases (18.7%). A history of UTI was reported in 13 cases (17.3%). The most common clinical presentation was acute pyelonephritis (59 cases; 78.7%) and followed by prostatitis (8 cases; 10.6%). Renal abscess was noted in 5 cases (6.7%) and prostatic abscess in 3 cases (4%). There were 36 cases of multidrug-resistant bacteria (48%). Community-acquired UTI were noted in 70 cases (93.3%). The mean duration of treatment was 18 ± 6 days. Surgery and radiological drainage were indicated in 4 (5.3%) and 2 cases (2.7%), respectively. The outcome was favourable in 58 cases (77.3%). Complications were noted in 10 cases (13.3%) represented mainly by acute renal failure in 4 cases (5.3%). Relapse was noted in 9 cases (12%) and reinfection in 6 cases (8%). Two patients died (2.7%). Conclusion Bacterial urinary tract infections were associated to complications such as renal and prostatic abscess, requiring surgery and long duration of treatment.
