|Abstract:||INTRODUCTION AND OBJECTIVES: ESBLs are enzymes that confer resistance to all penicillins, cephalosporins, and aztreonam. ESBL producing organisms causing urinary tract infections (ESBL-UTI) are increasing in incidence and pose a major burden to health care requiring treatment with expensive antimicrobials and prolonged hospital stay. Documented antibiotic susceptibility of ESBL organisms include meropenem (95-100%) and aminoglycosides (45-60%). This study evaluated the antibiotic sensitivity patterns of ESBL-UTI in Sri Lanka. METHOD: Patients with ESBL-UTI admitted to Professorial Medical Unit, Colombo North Teaching Hospital (CNTH) from January – June 2015 were recruited to the study. Their Urine culture and ABST reports were evaluated after obtaining informed written consent. RESULTS: Of 61 culture positive ESBL-UTIs, E. coli accounted for 53 (86.8%), followed by Klebsiella in the 8 (13.1%). The ESBL organisms were mostly sensitive to carbapenems; 58 (95%) to Meropenem and 45 (73.7%) to Imipenem. The other sensitivity patterns were 37 (60.6%) to Amikacin, and 28 (45.9%) to Nitrofurantoin. Meropenem resistance was observed in 3 (4.9%) and were E.coli. These three patients had received multiple antibiotics including meropenem in the recent past for recurrent UTI. CONCLUSIONS: It is evident from the above data that Carbapenems remain as the first line therapy for the majority of ESBL-UTI in the local setting. However 4.9 % prevalence of meropenem resistance is alarming compared to 0.4% prevalence in Pakistan and 0.02% prevalence in Germany. Such high prevalence of meropenem resistance should draw attention of clinicians and needs to implement measures to prevent emergence and spread of carbapenum resistant ESBL organisms in the country.|
