Insights
A rare case of peritonitis caused by Listeria monocytogenes serotype 1/2a in a patient undergoing automated peritoneal dialysis was successfully treated. Faroese salmon is suspected as the source of this Listeria monocytogenes infection.
Area of Science:
- Infectious Diseases
- Nephrology
- Microbiology
Background:
- Automated peritoneal dialysis (APD) patients are susceptible to infectious complications, including peritonitis.
- Listeria monocytogenes is an uncommon but serious cause of peritonitis in this population.
Observation:
- A 53-year-old woman on APD presented with abdominal pain and fever.
- Peritoneal fluid cultures identified Listeria monocytogenes serotype 1/2a as the causative pathogen.
Findings:
- The patient received a 2-week course of oral amoxicillin and a 3-week course of intraperitoneal vancomycin.
- Successful treatment resulted in no readmission for peritonitis.
Implications:
- This case highlights the importance of considering Listeria monocytogenes in APD-associated peritonitis.
- Contaminated food products, such as Faroese salmon, may represent a potential source of infection.
- Prompt and appropriate antibiotic therapy is crucial for favorable outcomes in APD peritonitis.
Abstract:
We present a case where Listeria monocytogenesserotype 1/2a was determined to be the causative agent of peritonitis in a patient on automated peritoneal dialysis. The patient, a 53-year-old Caucasian woman from the Faroe Islands was admitted to the National Hospital reporting of constant abdominal pain and a fever. Peritoneal cultures were positive for growth of L. monocytogenes. The patient was successfully treated with oral amoxicillin for 2 weeks and intraperitoneal vancomycin for 3 weeks. To date, the patient has not been readmitted due to peritonitis. The Faroese salmon was the suspected source of infection with L. monocytogenes.

Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
