Analysis of pathogenic bacteria of urinary tract infection in patients with mental disorders of different genders / 四川精神卫生

ABSTRACT

ObjectiveTo analyze the gender differences in the pathogen distribution and drug susceptibility of bacteria causing urinary tract infection among psychiatric inpatients in a hospital in Guangzhou， and to provide a basis for clinical diagnosis and rational use of drugs in treatment. MethodsClinical data of 326 psychiatric patients complicating urinary tract infection in a hospital in Guangzhou from 2019 to 2020 were retrospectively analyzed， including 126 males and 200 females. Data including gender， age， identification results of urinary tract pathogens from urine samples and drug susceptibility results were collected. The differences in bacterial distribution and drug resistance rate of urinary tract infection pathogens in patients of different genders were analyzed. ResultsA total of 326 strains of urinary tract infection bacteria were isolated， including 103 strains （31.60%） of multi-drug resistant bacteria. Male and female urinary tract infection in patients with multi-drug resistant bacteria were detected 52 strains （41.27%） and 51 strains （25.50%）， the detection rate of multi-drug resistant bacteria in female patients was significantly higher than that in male patients， with statistical difference （χ2=8.895， P<0.01）. In terms of bacterial distribution， the composition ratio of Escherichia coli in female patients was higher than that in male patients （χ2=14.794）， while the composition ratio of Acinetobacter baumannii and Pseudomonas aeruginosa was lower than that in male patients （χ2=13.665， 4.054）， with statistical difference （P<0.05 or 0.01）. The drug susceptibility results showed that Escherichia coli isolated from female patients were less resistant to various antibiotics such as ampicillin/sulbactam， aztreonam， cefepime， ceftazidime， levofloxacin， imipenem and meropenem than those from male patients （χ2=5.028~17.680， P<0.05 or 0.01）. ConclusionThe prevalence rate and bacterial distribution of psychiatric patients complicating urinary tract infection differ between patients of different genders， furthermore， the rate of drug resistance for Escherichia coli is lower in female patients than that in male patients.
