  • Title: Candida tropicalis in Peritoneal Dialysis-related Peritonitis Diagnosed by Matrix-assisted Laser Desorption/ionization Time-of-flight Mass Spectrometry.

    Abstract:
    Fungal peritonitis (FP) is a rare complication of peritoneal dialysis (PD). Candida tropicalis infections are rarely reported in literature. The authors present the first case of FP with peritoneal abscess due to C. tropicalis in a 22-year-old woman admitted to our hospital with septic shock. Abdominal tomography demonstrated an abscess in peritoneal space and intraluminal bubble appearance in femoral venous and arterial circulation. PD fluid specimens and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) analysis revealed fungus growth of C. tropicalis. Fluconazole therapy was administered accompanied by catheter removal and mechanical ventilation with vasopressor support. The patient recovered after 23 days of hospitalization and was discharged. FP represents high mobility and mortality unless infection source control and appropriate antimicrobial therapy are implemented accompanied by PD catheter removal. The use of MALDI-TOF MS for PD-related peritonitis pathogen identification can promote early identification and appropriate antibiotic therapy, especially in C. tropicalis infection.
