Candida parapsilosis in Late Prosthetic Joint Infections Among Immunocompetent Patients: A Case Series
Abstract
Introduction: Fungal prosthetic joint infections (PJIs) are very rare in immunocompetent patients. PJI can present either early, delayed, or as late chronic infections. Diagnosis of fungal PJI presenting late is challenging due to the difficulty in isolation as well as the clinical presentation very similar to an aseptic loosening. There are no clear guidelines regarding the management of these patients. Case Report: We present five cases of Candida parapsilosis PJI presenting as late chronic infections. All five patients were culture-negative preoperatively, immunocompetent, and with good soft-tissue condition. There were three infected knee prostheses and two infected hip hemiarthroplasty. All of them were treated with extensive debridement, meticulous sampling, and extended culture. We treated all of them with long-term antifungals without any disease reactivation or recurrence till the last follow-up. Conclusion: Fungal infection should be suspected in immunocompetent patients presenting early with features of aseptic loosening but without typical signs of periprosthetic infection. Revision with long-term suppressive therapy can give good results in these patients.
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
