Retrospective Analysis of Spectrum of Infections and Antibiotic Resistance Pattern in Chronic Kidney Disease Patients on Maintenance Hemodialysis in a Tertiary Care Centre in North India.

INTRODUCTION

Hemodialysis patients are at risk of infections. This study examines the spectrum of infections and antibiotic resistance patterns.

METHODS

We retrospectively reviewed the records of 586 hemodialysis patients from May 2018 to April 2020 in a tertiary care hospital in North India.

RESULTS

The study identified 99 episodes of confirmed infections. Urinary tract infections were the most common type of infections (55.5%), followed by catheter-related bloodstream infections (CRBSI) (definitive 21.2%). Other infections were pneumonia (8.1%), tuberculosis (6.1%), skin and soft tissue infection (4.0%), dengue fever (3.03%), and empyema thoracis (1.0%). Overall, (33.3%) was the most common organism isolated. The most frequent uropathogens recovered were (54%). In confirmed CRBSI, (23.8%) and MSSA (23.8%) were the most common pathogen isolated. (37.5%) was the most common pathogen in pneumonia. Uropathogens showed the highest resistance to fluoroquinolones (93.3%-100%). Pathogens isolated in CRBSI showed maximum resistance to ciprofloxacin (100%). In pneumonia, the highest resistance was seen to third-generation cephalosporins (75%-100%).

CONCLUSION

Though the bacterial spectrum remains the same over time, antibiotic resistance is changing in uropathogens. There is a trend of predominance of Gram-negative bacterial infections in CRBSI. Tuberculosis incidence rate was much higher than the general population. There is a need for nationwide and worldwide continuous surveillance.
