BACKGROUND: Fungal peritonitis is a relatively uncommon infection in peritoneal dialysis patients. However, it can be associated with significant morbimortality. In recent reports, Candida species and other filamentous fungi have been reported as being aetiological agents. Thermoascus species are ubiquitous, thermophilic fungi, with an anamorph in the Paecilomyces genus. Here we present the first report of fungal peritonitis by Thermoascus crustaceus from Chile.
CASE REPORT: We present the case of an 83-year-old female patient, with a history of cholecystectomy, hernia repair, severe arterial hypertension, hip and knee osteoarthritis and several episodes of peritoneal dialysis with a cloudy exudate. Bacterial cultures were negative. In addition, a history of two months with intermittent fever peaks mainly in the evening was reported. Blood culture bottles inoculated with peritoneal fluid revealed the presence of fungal growth. Morphological and molecular studies allowed us to identify the aetiological agent as Thermoascus crustaceus. An antifungal susceptibility test was performed using the M38-A2 method, developed by the Clinical and Laboratory Standards Institute (CLSI). The MIC values to amphotericin B, itraconazole, voriconazole and echinochandins were 0.5, 0.25, 0.25 and 0.125μg/ml, respectively. Antifungal treatment with amphotericin B was prescribed, with good patient progress.
CONCLUSIONS: Fungal peritonitis is a very rare entity. Moreover, the spectrum of fungal pathogens continues to expand, a reason for which morphological and molecular studies are necessary for a rapid diagnosis.
