Non-typhi Salmonella enterica urinary tract infections

Area of Science:

• Infectious Diseases
• Urology
• Microbiology

Background:

• Non-typhi Salmonella enterica urinary tract infections (UTIs) are infrequently documented.
• Understanding their clinical spectrum and risk factors is crucial for effective management.

Purpose of the Study:

• To characterize the clinical presentations of non-typhi Salmonella enterica UTIs.
• To identify associated risk factors and patient outcomes.

Main Methods:

• Retrospective analysis of 20 cases of non-typhi Salmonella enterica isolated from urine samples.
• Data collected from university hospitals in Île-de-France and Paris between 1996 and 2014.

Main Results:

• The average patient age was 57 years, with presentations including pyelonephritis, cystitis, and prostatitis.
• Eight cases of bacteremia were noted; diarrhea was common. Immunodeficiency, diabetes, or uropathy were present in several patients.
• Complications like spondylitis and purulent pleurisy occurred, but all patients recovered with antibiotic treatment.

Conclusions:

• Non-typhi Salmonella enterica UTIs are rare, primarily affecting elderly patients with compromised immunity or underlying urological conditions.
• These infections, though uncommon, are treatable with antibiotics, leading to positive patient outcomes.
