Abstract
Prosthetic joint infection (PJI) due to Candida spp. is a severe complication of arthroplasty but is little reported. This study describes Candida PJI epidemiology, management and outcome. We performed a retrospective, observational multinational study with support of the European Society of Clinical Microbiology and Infectious Diseases (ESCMID). Patients diagnosed with PJI due to Candida between 1990-2021 were included. Demographic, clinical, laboratory, imaging, medical/surgical treatment, and outcome data were collected within a standardized database. Treatment failure was defined either as a Candida infection recurrence, superinfection, or death due to infection. Data from 151 patients, across 18 centers were analyzed. Mean age was 69.5±13.1yo, 78 (51.7%) patients were male, and 21 (13.9%) were immunosuppressed. Site of infection included hip (55.0%), knee (41.7%), shoulder (2.6%), and femur (0.7%). Twenty-five (16.6%) patients were febrile, and 58 (38.4%) had fistula. Mean number of previous surgeries on the same anatomical site was 3.3±2.3. Surgeries were DAIR (33.8%), one-stage exchange (19.9%), two-stage exchange (39.1%), implant removal (6.0%). Candida species identified were C. albicans (60.3%), C. parapsilosis (26.5%), C. glabrata (7.3%), and C. tropicalis (5.3%). Co-infection with bacteria was found in 69 (45.7%) cases. Fluconazole (62.9%) and caspofungin (14.6%) were the main antifungal agents prescribed for 148.6±167.5 days. Favorable outcome was found in 54/144 (37.5%) cases. Failure was associated with the number of previous surgeries (OR 1.249, 95%CI 1.061-1.469; p-value=0.007), while treatment by fluconazole was associated with cure (OR 0.336, 95%CI 0.160-0.707; p-value=0.004). This study provides epidemiologic and outcome data on Candida PJIs. Although poor overall, the prognosis didn't seem associated with immunosuppression, type of surgery, fungal species or treatment duration. Aucun lien d'intérêt
