Peritonitis due to Staphylococcus sciuri in a patient on continuous ambulatory peritoneal dialysis

Area of Science:

• Nephrology
• Infectious Diseases
• Microbiology

Background:

• Continuous ambulatory peritoneal dialysis (CAPD) is a treatment for kidney failure.
• Peritonitis is a serious complication of CAPD.
• Coagulase-negative staphylococci (CoNS) are known causes of CAPD peritonitis, but Staphylococcus sciuri is rarely implicated.

Observation:

• A patient undergoing CAPD developed peritonitis.
• The peritonitis was initially caused by Staphylococcus aureus.
• Subsequently, the patient experienced a second episode of peritonitis caused by Staphylococcus sciuri.

Findings:

• Staphylococcus sciuri, a species of coagulase-negative staphylococci, was identified as the causative agent of CAPD peritonitis.
• This is a rare occurrence, with limited previous reports linking S. sciuri to CAPD peritonitis or endocarditis.
• The case demonstrates S. sciuri as a potential pathogen in CAPD-associated infections.

Implications:

• Accurate identification of CoNS species is crucial for effective CAPD peritonitis management.
• This finding expands the spectrum of known pathogens causing CAPD peritonitis.
• Further surveillance may be needed to understand the prevalence and clinical significance of S. sciuri in CAPD patients.
