Peritoneal dialysis-related peritonitis caused by Stephanoascus ciferrii: A Case Report

Stephanoascus ciferrii, a conditional pathogenic fungus prevalent in nature, is more frequently encountered in patients with compromised immunity. However, the literature rarely reports infections caused by Stephanoascus ciferrii in peritoneal dialysis patients. Here, we detail the case of a 66-year-old female suffering from renal failure who experienced catheter-related infection during peritoneal dialysis. Dialysate turbidity prompted the detection of Stephanoascus ciferrii in both peritoneal dialysate and tubes through microbiological cultures. Subsequent treatment involved antifungal drugs and a transition to hemodialysis, resulting in the disappearance of peritonitis symptoms and the patient's discharge. In recent years, fungal infections, particularly dialysis-related infections, are on the rise. This marks the first reported case of catheter-related peritonitis infection caused by Stephanoascus ciferrii. Compared to bacterial infections, fungal infections pose challenges due to limited drug options, significant side effects, and prolonged treatment durations. Hence, prompt pathogen diagnosis and drug sensitivity testing are crucial for effective clinical treatment. In essence, this scientific case report underscores the uncommon occurrence of catheter-related peritonitis attributed to Stephanoascus ciferrii in a peritoneal dialysis patient with renal failure, emphasizing the distinctive management challenges and underscoring the critical significance of prompt diagnosis and suitable intervention in such instances.
