Endocarditis caused by Candida albicans was induced in rabbits after insertion of a catheter across the aortic valve. The mean survival time of 34 rabbits was 26 days. Only 7% of temperature recordings taken were elevated. Candida was recovered from only 9% of blood cultures taken. Precipitating and agglutinating serum antibody was detected after 12 days of infection. Antibody titers rose progressively until death in rabbits with endocarditis, whereas titers peaked early and subsequently decreased in animals that received an intravenous injection of C. albicans without precatheterization. Three groups of rabbits were treated for 6 days with amphotericin B, 5-fluorocytosine, or the two durgs in combination. Amphotericin B alone reduced the mean titer of organisms from log10 8.79 +/- 1.46 to log 10 3.1 +/- 1.9 colony-forming units/g. 5-Fluorocytosine was less effective (mean titer after 6 days of therapy was log10 7.4 +/- 0.33 colony-forming units/g). The addition of 5-fluorocytosine to amphotericin B did not increase the rate at which Candida cells were eradicated from the vegetations. These in vivo results corrleated with the failure to demonstrate an increased rate of fungicidal activity in vitro with the two drugs.

The prevention of Candida endocarditis in the rabbit was easily accomplished with a single intramuscular injection of 75 mg of 5-FC (A predominantly fungistatic agent) per kg either 40 min before, or at the same time as, the intravenous challenge with Candida albicans. Renal infarcts were observed more often in rabbits with infected valvular vegetations than in control rabbits with sterile endocarditis. The prophylactic effect of 5-FC is greater in aortic vegetations than in the kidneys. This may be related to differences in the pathophysiology of infection and the pharmacokinetics of 5-FC in the two areas.

No controlled trials of therapy for invasive aspergillosis have been done. This review appraises 2,121 cases reported in 497 articles in the literature and analyzes 440 courses of treatment of infection at various body sites in 379 patients. The exclusion of early failures of therapy skews the results toward a favorable outcome. The rate of response to amphotericin B is 55%. Mortality from pulmonary aspergillosis in bone marrow transplant recipients exceeds 94% regardless of therapy, as does that from cerebral aspergillosis in all hosts. Amphotericin B (1 mg/[kg.d]) with flucytosine lowers mortality in neutropenic patients with pulmonary aspergillosis who did not receive a bone marrow transplant; relapse is common. Surgical debridement of aspergillus maxillary sinusitis is usually curative in nonimmunocompromised patients, whereas it increases mortality among neutropenic patients. Valve replacement is essential for aspergillus endocarditis. Both vitrectomy and intravitreal amphotericin B treatment are essential for aspergillus endophthalmitis. Flucytosine is somewhat useful clinically. Itraconazole shows efficacy in the treatment of pulmonary, skeletal, and pericardial aspergillosis. Although liposomal amphotericin B is less toxic than standard preparations of the drug, relevant data are limited. The proposed potentiation of amphotericin B by rifampin is unsupported by clinical data. Despite "conventional" therapy, mortality from invasive aspergillosis remains high; new approaches must be investigated.

We provide a review of current literature and report on a case of electronic device infective endocarditis with C. tropicalis. A 64-year-old man presented for revision of his implantable cardioverter defibrillator. Echocardiography revealed extensive vegetations attached to the Eustachian valve and in the right ventricular apex. Microbiological findings presented C. tropicalis on the explanted material. The patient refused additional surgical intervention. We successfully treated the patient with liposomal Amphotericin B and Flucytosine for 8 weeks.
