AIM: Meropenem Yearly Susceptibility Test Information Collection (MYSTIC) Program is a longitudinal global surveillance study to monitor in vitro data on microbial susceptibility in centers that prescribe meropenem. Results of the six years period (2002-2007) for the antimicrobial efficacy of meropenem compared to other broad-spectrum agents against Gram-negative and Gram-positive isolates collected at pediatric intensive care units of the University Hospital Center Zagreb in Croatia were reported.
METHODS: A total of 110 Gram-negative and 43 Gram-positive pathogens from pediatric specimens were tested. The minimum-inhibitory concentrations (MICs) were determined by broth microdilution method according to CLSI.
RESULTS: There was no resistance to either imipenem or meropenem observed for Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis. High resistance rates of K. pneumoniae to ceftazidime and gentamicin (50%) are a raising concern. Pseudomonas aeruginosa was the most resistant Gram-negative species with two (12%) of the strains resistant to meropenem, three (18%) to imipenem, 10 (47%) to gentamicin and six (35%) to piperacillin/tazobactam and ciprofloxacin. According to our results meropenem remains an appropriate antibiotic for the treatment of severe infections caused by Gram-negative bacteria in pediatric population.
CONCLUSIONS: The results indicate that meropenem has excellent potency and spectrum of activity despite being prescribed for a long time for the treatment of seriously ill patients, and still appears to be a reliable option for the initial empirical therapy of serious nosocomial infections in children. However, later studies have shown the emergence of carbapenem-resistant Gram-negative bacteria after 2008.
