Capnocytophaga canimorsus peritonitis in a pediatric peritoneal dialysis patient
1Section of Pediatric Nephrology, The Children's Mercy Hospital, University of Missouri at Kansas City, 2401 Gillham Road, Kansas City, MO 64108, USA,
Abstract:
Capnocytophaga canimorsus, a bacterium rarely encountered by clinicians, was responsible for the development of peritonitis in an 18-year-old white male on automated peritoneal dialysis following the puncture of his dialysis tubing by a domestic cat. Although more than 100 cases of septicemia caused by C. canimorsus have been reported, this is the first report of the organism causing peritonitis in a patient receiving peritoneal dialysis. Of interest, the patient had a prior episode of peritonitis secondary to Pasteurella multocida, also following transmission from the same cat.
Insights
Capnocytophaga canimorsus caused peritonitis in a peritoneal dialysis patient after a cat-related injury. This is the first reported case of this bacterium causing peritonitis in a patient undergoing peritoneal dialysis.
Area of Science:
- Microbiology
- Nephrology
- Infectious Diseases
Background:
- Capnocytophaga canimorsus is a rare bacterium that can cause severe infections.
- Peritoneal dialysis is a treatment for kidney failure, but patients are susceptible to infections.
- Cat-to-human transmission of bacteria can lead to serious health complications.
Observation:
- An 18-year-old male on automated peritoneal dialysis developed peritonitis.
- The peritonitis was caused by Capnocytophaga canimorsus.
- The infection occurred after his dialysis tubing was punctured by a domestic cat.
Findings:
- This is the first reported case of Capnocytophaga canimorsus causing peritonitis in a patient receiving peritoneal dialysis.
- Over 100 cases of C. canimorsus septicemia have been documented.
- The patient had a previous peritonitis episode caused by Pasteurella multocida, also from the same cat.
Implications:
- Clinicians should consider Capnocytophaga canimorsus in patients on peritoneal dialysis with peritonitis, especially after animal contact.
- This case highlights the importance of recognizing rare bacterial causes of infection in immunocompromised patients.
- Understanding transmission routes is crucial for preventing serious infections in dialysis patients.
