Urinary tract infection and Diabetes Mellitus-Etio-clinical profile and antibiogram: A North Indian perspective

Prevalence of recurrent urinary tract infections and its associated factors in female staff of reproductive age group in a medical college in central Kerala: a cross-sectional study

AIM

To study the prevalence of recurrent urinary tract infections (UTIs) and its associated factors in female staff of reproductive age group in a medical college in central Kerala.

INTRODUCTION

Recurrent UTIs can be defined as ≥ 3 episodes of UTIs within a period of 12 months. Females with recurrent UTIs have lower health-related quality of life compared to the general population; the incidence of UTI in women of reproductive age group is very common. This study focused on female employees of reproductive age group in a private medical college.

METHODS

A cross-sectional study was done among female staff of reproductive age group in a private medical college in central Kerala, with a sample size of 417. All female staff (18-49 years) were given a questionnaire and asked to fill it out. All those who filled out the questionnaire were included in the study according to both inclusion and exclusion criteria. Data entry and analysis were performed via Microsoft Excel 2019 and SPSS version 22.0.

RESULT

Our study of 417 participants revealed a prevalence of recurrent UTIs of 22.30% (95% CI = 18.3- 26.3%). Recurrent UTI was significantly associated with daily water intake, urination frequency, holding urine, foul-smelling vaginal discharge, constipation, pre-coital urination, and pre- and post-intercourse vaginal hygiene. Also, occupation was found to be significantly associated with recurrent UTI, with cleaning staff having higher odds.

CONCLUSION

Our study found the prevalence of recurrent UTI in 417 population as 22.30%. Prevention of recurrent UTI requires a daily intake of > 2 L of water and personal & sexual hygiene. Reducing recurrent UTIs enhances quality of life. Educating female staff is crucial.

Clinical Outcomes of Acute Pyelonephritis in Type 2 Diabetes Mellitus

Background Diabetes mellitus (DM) is a prevalent predisposing factor for urinary tract infections (UTIs). Among hospitalized patients with acute pyelonephritis, UTIs are more common, severe, and associated with worse outcomes, particularly in those with type 2 DM. Pyelonephritis in DM patients is more frequently bilateral and linked to greater complications, with 90% of emphysematous pyelonephritis (EMPN) and cystitis cases occurring in diabetic individuals. Objective This study aims to evaluate the clinical and microbiological profiles, treatment outcomes, and complications of acute pyelonephritis in patients with type 2 DM. Methods A six-month prospective observational study was conducted from March 2016 to August 2016 at Stanley Medical College and Hospital, Chennai, India. A total of 102 hospitalized patients presenting with symptoms suggestive of acute pyelonephritis were included. Data were collected using a clinical questionnaire and analyzed using IBM SPSS Statistics for Windows, Version 20.0 (Released 2011; IBM Corp., Armonk, New York, United States). Patients received culture-sensitive antimicrobial therapy, percutaneous drainage, and renal replacement therapy as required. Results Out of 102 patients, 80 (78.4%) had non-emphysematous pyelonephritis (NEMPN), and 22 (21.6%) had EMPN. The mean age was 55.2±10.9 years, with a female predominance of 63 (78.4%) participants. Escherichia coli was the most common organism isolated in 70 (68.6%) cases. Renal dysfunction was present in 67 (65.7%) patients, with a higher prevalence in EMPN (22, 100%) compared to NEMPN (45, 56.3%) (p<0.001). Mortality was observed in three (3.9%) patients, and 25 (24.5%) developed de novo or progressive chronic kidney disease. Conclusion Early diagnosis and aggressive management of EMPN in type 2 DM patients improve outcomes. Acute pyelonephritis is predominantly observed in women, with fever and loin pain as the most common symptoms. Escherichia coli is the primary pathogen, and renal dysfunction is frequent but often reversible. Mortality is low with appropriate management.

Similarities in Bacterial Uropathogens and Their Antimicrobial Susceptibility Profile in Diabetics and Their Non-Diabetic Caregivers at a National Diabetes Management and Research Centre, Accra-Ghana

BACKGROUND

Diabetes mellitus has some damaging effects on the genitourinary system and has been found to have adverse effects on the host immune system, resulting in higher risk of infections including urinary tract infections (UTI). Incidences of UTI caused by bacteria have been increasingly reported globally and the abuse of antibiotics leading to evolving resistant strains of antibiotics is a public health challenge for the management of this condition. Information on the difference in types of bacterial agents causing UTI in diabetic patients and non-diabetic individuals, and their susceptibility profiles, will facilitate effective management among these groups of patients. Therefore, this study aimed at determining the difference in prevalence of UTI, the causative bacteria, and their antimicrobial susceptibility profiles in diabetic patients and non-diabetic individuals at a diabetes management center.

METHODS

This was a prospective cross-sectional study conducted amongst 100 diagnosed diabetic patients and 100 non-diabetic individuals. Urine sample was collected aseptically and analyzed microbiologically for the presence of urinary tract bacterial pathogens. Drug susceptibility testing was conducted on the isolates by the Kirby Bauer method to ascertain the antibiotic susceptibility patterns.

RESULTS

Among the diabetic and non-diabetic individuals, urinary tract bacterial pathogens were observed in 28.0% and 26.0% of samples, respectively. The organisms were in the following proportions for diabetic and non-diabetic individuals, respectively: E. coli (14/28, 50% and 8/26, 30.7%), S. aureus (2/28, 7.1% and 4/26, 15.4%), K. pneumoniae (4/28, 14.3% and 8/26, 30.7%), K. ozoenae (2/28, 7.14% and 0/26, 0%), K. oxytoca (0/28, 0% and 4/26, 15.4%) and C. urealyticum (6/28, 21.4% and 2/26, 7.69%). The difference between the proportions of bacteria isolated was, however, not statistically significant (p-value = 0.894). Bacteria isolated from both diabetic and non-diabetic individuals were highly susceptible to most of the antibiotics tested, especially nitrofurantoin, cefuroxime, ceftriaxone, and cefotaxime.

CONCLUSION

This study has shown that similarities exist in prevalence of UTI, the causative bacteria, and their antimicrobial susceptibility patterns amongst diabetic patients and non-diabetic individuals at a diabetes management center. These data will help in the management of UTI among these individuals.

Bacterial profile and antibiotic susceptibility pattern of uropathogens causing urinary tract infection in the eastern part of Northern India

Urinary tract infection (UTI) is a common infectious disease that affects men and women. It is a significant health concern due to multidrug-resistant (MDR) organisms. Therefore, it is necessary to have a current understanding of the antibiotic susceptibility (AS) pattern of uropathogens to manage UTI effectively. Since the bacterial pathogen causing UTI and its AS vary with time and place, the prevailing AS pattern of the causative agents are essential for empirical antibiotic therapy. This study aims to determine the prevalence and AS of uropathogens isolated from UTI patients in the eastern part of Northern India. The study was carried out between November 2018 and December 2019. Clean catch midstream urine samples were collected and processed using standard guidelines for microbiological procedures. Positive microbiological cultures were found in 333 of the 427 patients, where 287 were gram-negative bacteria (GNB), and 46 were gram-positive bacteria (GPB). Females had a higher prevalence of UTI (60.7%) than males (39.3%) (p = 0.00024). The most susceptible age group in females was 18–50 years as compared to males, whereas at the age of 51–80 years and >80 years males were more susceptible than females (p = 0.053). The most prevalent pathogen identified were Escherichia coli (55.0%), followed by Proteus sp. (6.9%), Klebsiella pneumoniae (6.6%), Pseudomonas aeruginosa (6.3%), of which 96.0% were MDR bacteria. The susceptibility pattern of our study also revealed that amikacin, gentamycin and imipenem were the most effective drugs against GNB. In contrast, nitrofurantoin, vancomycin, and chloramphenicol were the most effective drugs against GPB. According tothe findings, MDR pathogens are very much prevalent. Since UTI is one of the most frequent bacterial diseases, proper management necessitates extensive investigation and implementation of antibiotic policy based on AS patterns for a particular region.
