Increased macrolide resistance in Streptococcus pneumoniae in Slovakia may be linked to increased macrolide consumption.

OBJECTIVES

Given the widespread use of macrolide antibiotics and growing concerns over antimicrobial resistance, this study aimed to investigate recent trends in macrolide consumption in Slovakia and to determine the corresponding changes in Streptococcus pneumoniae resistance in a paediatric cohort.

METHODS

We conducted a retrospective analysis of 1,083 nasal swab cultures from children with recurrent respiratory infections and atopy, comparing two distinct 5-year periods: 2008-2012 and 2019-2023. Consumption data was based on the European Centre for Disease Prevention and Control reports.

RESULTS

National data confirmed that Slovakia has one of the highest consumption rates of macrolides, lincosamides, and streptogramins (ATC group J01F) in Europe. The comparative analysis of patient samples revealed a statistically significant 11% increase in erythromycin-resistant S. pneumoniae (p < 0.001) and a 5% increase in clindamycin-resistant strains (p < 0.001) between the two study periods.

CONCLUSIONS

The concurrent rise in macrolide consumption and S. pneumoniae resistance in Slovakia highlights a significant public health threat. These findings underscore the urgent need for robust antibiotic stewardship programmes and the promotion of rational prescribing practices to preserve the efficacy of macrolides.
