Peritonitis in a continuous ambulatory peritoneal dialysis patient by two different species of enterococci: A rare...

Area of Science:

• Nephrology
• Infectious Diseases
• Microbiology

Background:

• Continuous ambulatory peritoneal dialysis (CAPD) is a common treatment for end-stage renal disease.
• Peritonitis is a serious complication of CAPD, often caused by bacterial infections.
• Enterococcal species are a known cause of CAPD-related peritonitis.

Observation:

• This report details a rare instance of CAPD peritonitis caused by two distinct enterococcal species.
• The isolated pathogens were vancomycin-sensitive Enterococcus faecalis and vancomycin-resistant Enterococcus faecium.
• The patient presented with symptoms indicative of peritonitis.

Findings:

• The study successfully identified dual enterococcal species contributing to peritonitis in a CAPD patient.
• Vancomycin resistance was confirmed in the Enterococcus faecium isolate.
• The case highlights the challenge of treating infections with multidrug-resistant organisms in immunocompromised patients.

Implications:

• This case underscores the importance of accurate pathogen identification and susceptibility testing in CAPD peritonitis.
• It demonstrates the clinical utility of linezolid as a treatment option for vancomycin-resistant enterococcal infections.
• Findings may inform treatment guidelines for complex CAPD-related infections, particularly those involving resistant bacteria.
