Antibiotic susceptibility in commonly isolated pathogens from urinary tract infection in a cohort of subjects from low socioeconomic strata

Abstract

Background and Objective: Urinary tract infection is one of the commonest infections seen in clinical practice. Lack of compliance and unjustified antibiotic prescriptions has resulted in bacterial resistance and is proving as a major challenge in the management of these infections. Our aim was to identify the sensitivity pattern of commonly used antibiotics against urinary tract infections so as to suggest an improvised line of action against bacteria causing urinary tract infections’.

Method: This was a hospital based cross sectional study extended over a period of four months. Patients were recruited from outpatients department of a tertiary care hospital in an industrial area of Karachi. Adult patients with symptomatic and documented UTI in urine detailed report (pus cells >10) were enrolled after informed consent. A clean catch midstream urine was collected for culture and sensitivity testing using the standard microbiological procedure. Data is analyzed on SPSS 16.

Results: A total of 184 samples were collected in 4 months. The Male to Female ratio was 1:2 (n=58/126) with mean age 48.5±12 years. 83(45.6%) patients were between 45-60 years. Most common isolated pathogen was Eschericia coli 108(59%) followed by staphylococcus aureus 30(16.4%) and Klebsiella 20(11%). 55(30%) pathogens showed sensitivity to 4-6 antibiotics, 22(12%) strains to 7-9 antibiotics, 33(18%) were sensitive to ≤3 drugs and in 3(1.6%) patients resistance to all antibiotics is seen. The more resistant pathogens were sensitive to intravenous antibiotics alone.

Conclusion: In this low socioeconomic cohort with UTI nearly half the isolated pathogens has shown resistance to most of the commonly used antibiotics recommended in the guidelines especially the floxacin group probably because of its unwarranted use. Therefore, a revised line of management should be developed locally in accordance with the susceptibility pattern of the urinary pathogens to avoid further resistance as well as morbidity of the patient.
