  • Title: Periprosthetic candidal infections following arthroplasty.
    Author: Darouiche RO, Hamill RJ, Musher DM, Young EJ, Harris RL.
    Journal: Rev Infect Dis; 1989; 11(1):89-96. PubMed ID: 2916098.
    Abstract:
    Candidal infection after prosthetic arthroplasty has been reported in six previous cases, to which four cases are now added. Candida albicans was the offending organism in four patients, Candida parapsilosis in three, Candida tropicalis in two, and Candida (Torulopsis) glabrata in one. None of the 10 patients had evidence of disseminated candidiasis, and, except for the uniform presence of a prosthesis, other underlying factors that are generally associated with candidal infections were present in only three. Clinical features that distinguished periprosthetic from natural bone and joint infection included an older patient population, the usual lack of predisposing factors other than the prosthesis, and the absence of evidence of disseminated candidiasis. All patients were treated with removal of the prosthesis and antifungal therapy, consisting of amphotericin B alone (six patients) or combined with 5-fluorocytosine (three patients) or ketoconazole (one patient). Infection appeared to be cured in nine of the 10 patients, but the follow-up was less than 1 year in five cases. Replacement with a new prosthetic joint was attempted in only two cases and successful in only one. Direct inoculation of organisms during surgery or transient unrecognized candidemia may initiate periprosthetic infection, which might then be promoted by favorable local factors, both mechanical and molecular. The role of prosthetic materials, candidal adhesins, and human factors such as fibronectin in initiating these infections has yet to be characterized.
