ABSTRACT
Background: Urinary tract infections (UTIs) are amongst the most common bacterial infections, affecting about 150 million individuals per year.Urinary tract infection (UTI) is one of the most common diseases in human societies which occur in women more than men. Women of all ages are more likely to experience such an infection than men, while half of them may be affected by a uropathogen once in their lives, and 25-30% may develop recurrent UTIs not associated with any functional or anatomical abnormality. The aim of this study was to explore the prevalence of antibiotic resistance of urinary tract infections in immunocompromised patients. Material & Methods: This was a retrospective observational study and was conducted in the Department of Medicine of Dhaka Central International Medical College and Hospital, and National Institute of Kidney Diseases & Urology, Dhaka, Bangladesh during the period from June, 2021 to June, 2022. We included 70 immunocompromised patients with UTI. Results: In our study we found 44% patients were aged between 18-30 years old and 83% of our patients were female. Among all respondents, 58 patients were culture positive. We found 38% & 62% and 33% & 67% had history of upper & lower UTI in female and male patients respectively, 29% & 36% and 17% & 25% had urethritis & cystitis in female and male patients respectively. We found culture positive patients with E. coli (41%), Klebsiella spp.(19%), Enterobacter spp.(16%) and 12% with Pseudomonas spp in our study. We found amoxicillin showed resistance to E. coli (58.3%), Staphylococcus (75%), & Klebsiella (36.4%) and amikacin showed resistance mostly to E. coli(50%), Klebsiella (54.5%) & Pseudomonas (42.9%). Conclusion: In our study, we found the most common MDR pathogen among patients with UTI in our institution was E. coli & Staphylococcus. We discovered that being above 40 years old, having DM, CKD and previously received antibiotic medication inappropriately were risk factors for the development of MDR infection. Given the high prevalence of multidrug resistant uropathogens among immunocompromised patients, the growth in Penicillin resistance is alarming. We discovered the significant incidence of MDR bacterial strains, adherence to currently suggested empiric therapy is extremely challenging and is linked with high failure rates.
