    Objectives: To assess Asian data from Global Prevalence Study on Infections in Urology (GPIU study) which has been performed more than 10 years. Methods: Seventeen Asian countries participated in the GPIU study between 2004 and 2013. Data for these countries were collected from the web-based GPIU database. The point prevalence of urinary tract infections (UTI) and antimicrobial susceptibility of representative pathogens were analysed for Asian geographic regions. Results: A total of 6706 patients (5271 male, 1435 female) were assessed during the study period, and 659 patients were diagnosed with a UTI (9.8%). Of these UTI patients, 436 were male and 223 were female. Mean patient age was 54.9 +/- 19.3 years. Pyelonephritis and cystitis were the most common clinical diagnoses, representing 30.7% and 29.9% of patients, respectively. Escherichia coli was the most frequently identified uropathogen (38.7%). For the patients with urinary tract infection, cephalosporins were the most frequently used antibiotics (34.4%), followed by fluoroquinolones (24.1%), aminoglycosides (16.8%). Fluoroquinolone resistance was relatively high (ciprofloxacin 54.9%, levofloxacin 39.0%), and cephalosporin resistance 42% (42.5-49.4%). Of the antibiotics evaluated, uropathogens had maintained the highest level of susceptibility to amikacin and imipenem (24.9% and 11.3% resistance rates, respectively). Conclusion: Uropathogens in many Asian countries had high resistance to broad-spectrum antibiotics. Knowledge of regional and local resistance data and prudent use of antibiotics are important for proper management of UTI in Asian countries.

    Healthcare-associated urinary tract infections in hospitalized urological patients-a global perspective: results from the GPIU studies 2003-2010
    (Springer, 2014) Cek, Mete; Tandogdu, Zafer; Wagenlehner, Florian; Tenke, Peter; Naber, Kurt; Bjerklund-Johansen, Truls Erik
    European Section for Infections in Urology has been conducting an annual prevalence survey investigating various aspects of healthcare-associated urinary tract infections (HAUTI) since 2003. The data on various clinical categories of HAUTI, the contamination status of HAUTI patients who underwent any urological intervention with regard to microorganisms isolated, resistance status and antibiotics used to treat HAUTI will be presented. Of a total of 19,756 patients screened, 1,866 patients had HAUTI (9.4 %); 1,313 males (70.4 %) and 553 (29.6 %) females. Mean age was 59.9 +/- A 18.2. Asymptomatic bacteriuria (ASB) and cystitis were the most frequent clinical diagnoses representing 27.0 and 26 % of all HAUTI, respectively. Echerichia coli was found to be the most frequent uropathogen (544 of 1,371 isolates) (39.7 %). Fluoroquinolones were preferred in 26.6 % of cases followed by cephalosporins (23.3 %), aminoglycosides (14.1 %) and penicillins (13.8 %). High global resistance rates to ciprofloxacin (> 50 %), cephalosporins (35-50 %) and penicillins (50 %) were found in the GPIU studies 2003-2010. We showed that around 10 % of hospitalized urological patients are at risk to develop HAUTI often caused by multiresistant uropathogens. Increased antibiotic use often with broad-spectrum antimicrobials will inevitably be followed by increasing bacterial resistance. To interrupt such a vicious cycle, our results suggest (1) there is still room for improvement in surgical prophylaxis in terms of limiting exposure to antibiotics and (2) far too many patients with ASB are being treated which shows that the new proposal of classification should be adopted where ABS is regarded as colonization and not as an infection to be treated.
