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.
