COVID-19 pandemic impact on antibiotics sensitivity of E. coli and K. pneumoniae from urine specimens: a retrospective study.

INTRODUCTION

Escherichia coli and Klebsiella pneumoniae are common organisms associated with urinary tract infections. The COVID-19 pandemic has had a negative impact on antibiotics misuse globally. This study analyzed the antibiotic susceptibility for these two pathogens isolated from urine samples during the period of 18 months before and after the COVID-19 pandemic.

METHODOLOGY: This retrospective study was conducted in Al-Karak government referral and teaching hospital in Jordan. The study included two groups; group A included urine samples from September 2018 to March 11, 2020, while group B from March 12, 2020 to August 2021. Samples were analyzed using the automated VITEK 2 system and the analysis of results was done using the WHONET version 5.6.

RESULTS

A total of 642 E. coli and 113 K. pneumoniae were isolated and analyzed. The antibiogram showed a significant overall increase in antibiotic susceptibility of both bacteria during the pandemic period (group B). The sensitivity has significantly increased by 75% (15/20) and 50% (10/20) for all antibiotics used for E. coli and K. pneumoniae respectively. On the other hand, E. coli showed a significant increase in resistance to ceftriaxone (13.4%) and gentamicin (6.4%). A similar trend of an increase in resistance to gentamicin (17.4%) was also noticed among K. pneumoniae isolates.

CONCLUSIONS

The antimicrobial susceptibility pattern for urine isolates showed an increased overall sensitivity and an increased resistance to ceftriaxone and gentamicin during the pandemic period. Our results highlight the need for revising and updating the antimicrobial stewardship programs post-COVID pandemic utilizing local data.
