National Trends of Antimicrobial Resistance in Uncomplicated Cystitis

Acute uncomplicated cystitis is a common bacterial infection of the urinary bladder in women. Antibiotic resistance against Escherichia coli is increasing nationwide in Korea; therefore, we reviewed the local available data regarding acute cystitis. The recently determined susceptibilities of E. coli to gentamicin, fluoroquinolone, 3rd generation cephalosporin, and amikacin are 75%, 85-95%, 95%, and 97%, respectively. The resistance rates of E. coli to trimethoprim/sulfamethoxazole, fluoroquinolone, and even 3rd generation cephalosporin are higher in Korea compared with other countries, however, the studies that determined those resistance rates included data collected at tertiary referral hospitals, which may have been overestimated. Continuous monitoring of antibiotic resistance and opportune establishment and revision of treatment guidelines are required for the optimal management of acute cystitis.
