Fluconazole treatment of catheter-related right-sided endocarditis caused by Candida albicans and associated with endophthalmitis and folliculitis.

An unusual case of catheter-related right-sided endocarditis, endophthalmitis, and extensive folliculitis, apparently caused by a single DNA biotype of Candida albicans, was successfully treated with a 6-month course of fluconazole plus two intravitreous doses of amphotericin B. The patient was a 21-year-old man who underwent colectomy for diffuse polyposis and developed the clinical syndrome just described following total parenteral nutrition for the treatment of purulent anal fistulas. Fluconazole was initially administered at a daily dose of 200 mg, with 600 mg daily given after 4 weeks. Clinical improvement resulted, with no relapse during 14 months of follow-up. Sequential measurements by an enzyme-linked immunosorbent inhibition assay demonstrated that levels of circulating mannoprotein antigen of C. albicans fell from 75 ng/mL to less than 1 ng/mL after the institution of fluconazole therapy. These observations seem to confirm previous reports on the efficacy of fluconazole as sole therapy for candidal endocarditis and suggest a role for serological studies in clinical monitoring of severe candidal infections.
