[Resistance of pathogens of community-acquired urinary tract infections: lessons from Russian multicenter...

The choice of antimicrobials for the treatment of urinary tract infections (UTIs) is determined by many factors, however, at present, population antibiotic resistance of uropathogens is used as one of the most important criteria. At the same time, there are cases when the clinical efficacy of an antimicrobial drug does not correlate with in vitro activity, in particular, such discordance was found for fosfomycin trometamol. Comparison of data from microbiological studies of UTI pathogens performed at different times is of great practical and scientific interest. At the same time, such comparisons have limitations, such as the use of different criteria for interpreting the sensitivity of microorganisms, the peculiarities of the formation of the studied patient population, and collection of strains in different geographical areas. Therefore, for all the seeming simplicity and clarity of the data on the sensitivity of uropathogens, their use to substantiate rational antimicrobial therapy is associated with numerous nuances that can significantly distort their objective assessment. In this connection, it is important to conduct not only microbiological, but also clinical studies to obtain data on the comparative effectiveness of the antimicrobials used.
