Uropathogens and their antibiotic susceptibility patterns among diabetic patients at st. john of god hospital, duayaw nkwanta, Ghana: a cross‐sectional study

TL;DR

This study finds that diabetic patients in Ghana commonly have urinary tract infections caused by bacteria like E. coli, with high antibiotic resistance, suggesting the need for tailored treatments.

Contribution

The study provides new local data on uropathogen prevalence and antibiotic resistance patterns in diabetic patients in Ghana.

Findings

Escherichia coli was the most common uropathogen among diabetic patients.

High antibiotic resistance was observed in Klebsiella pneumonia and Proteus mirabilis.

Suboptimal glucose levels and glucosuria were significant risk factors for uropathogen occurrence.

Abstract

Uropathogens are microorganisms that cause urinary tract infections (UTIs). Owing to higher blood glucose levels and compromised immune functions, treatment of uropathogens in diabetic patients is a challenge.

This study aims to assess the prevalence of uropathogens and their antibiotic susceptibility among diabetic patients at St. John of God Hospital at Duayaw Nkwanta (SJGHDN) in the Ahafo region of Ghana.

The cross‐sectional study recruited 175 diabetic patients at SJGHDN between August and September 2023. Questionnaires were used to collect patients’ background information. Fasting Blood Sugar (FBS) was assessed by using a glucometer. Urine samples were examined for the presence of uropathogens. A sterile inoculating loop with a calibrated volume of 2 µl was used for plating. Each colony equals 500 CFU/mL. Significant uropathogen was determined by multiplying the counted colonies by 500 to obtain CFU/mL. Positive uropathogen was defined as CFU ≥ 105/mL. Significant uropathogen was defined as ≥200 colonies per sample. The disc diffusion method was used to determine antibiotic susceptibility.

Out of the 175 patients, 19.4% expressed various uropathogens with Escherichia coli being the predominant. Suboptimal glucose level was the most significant risk factor (p = 0.038). Glucosuria (p = 0.036), hazy urine (p = 0.028), positive leukocyte esterase (p = 0.001), and pus cells in urine sediment (p = 0.020) were significant indicators of uropathogen occurrence. Klebsiella pneumonia and Proteus mirabilis were resistant to ≥4 antibiotics. Amikacin, nitrofurantoin, levofloxacin, ciprofloxacin, and ceftriaxone demonstrated efficacy against the isolates.

This study underscores the notable prevalence of uropathogens in diabetic patients and the alarming levels of antibiotic resistance observed. The results highlight the critical need for vigilant monitoring and customized treatment approaches, particularly for diabetic patients exhibiting risk factors such as elevated urine glucose levels, cloudy urine, and presence of leukocyte esterase and pus cells in urine sediment. The significant resistance to frequently used antibiotics like co‐trimoxazole and tetracycline points to the necessity of routine susceptibility testing and the use of alternative antibiotics for effective treatment. These findings can assist healthcare providers in more effectively managing and preventing UTIs in diabetic populations.
