Consensus review of the epidemiology and appropriate antimicrobial therapy of complicated urinary tract infections in Asia-Pacific region
Abstract
Urinary tract infections (UTIs) are among the most prevalent infectious diseases in the general population. They cause a substantial financial burden in the community and are associated with significant morbidity and mortality, particularly in hospitals. With increased rates of antimicrobial resistance, especially in the Asia-Pacific region, treatment of complicated UTIs (cUTIs) can be challenging for clinicians. Consideration of an optimal antimicrobial agent should be based on local resistance patterns, patient-specific factors, pharmacokinetic and pharmacodynamic principles, and cost. In the Asia-Pacific region, nearly half of Escherichia coli urinary isolates were resistant (including intermediate and resistant) to levofloxacin or ciprofloxacin and ≥30% were resistant to third-generation cephalosporins (cefotaxime, ceftriaxone, and ceftazidime) and cefepime. Overall, 33% of urinary E. coli isolates exhibited extended-spectrum β-lactamase (ESBL)-producing phenotypes. Prevalence of ESBL-producing urinary E. coli was highest in India (60%), followed by Hong Kong (48%) and Singapore (33%). All urinary isolates of E. coli were susceptible to both ertapenem and imipenem. All urinary isolates of Klebsiella pneumoniae were susceptible to imipenem and 4% of them were resistant to ertapenem. Care should be exercised when using trimethoprim-sulfamethoxazole (TMP-SMX), fluoroquinolones, and cephalosporins for the empirical treatment of UTIs, particularly cUTI among moderately to…
