| - Background. Chronic disseminated candidiasis (CDC) is typically observed during neutrophil recovery in patients with acute leukemia and requires protracted antifungal therapy. Objective. Our objective was to document the efficacy and tolerance of corticosteroid therapy (CST) in patients with symptomatic CDC, including those who experienced fever and abdominal pain despite ongoing antifungal therapy. Methods. We performed a retrospective, multicenter study involving 10 pediatric and adult patients who experienced ongoing symptomatic CDC despite receipt of appropriate antifungal therapy for whom adjuvant oral CST was initiated. Results. All cases of CDC were proven or probable, as determined on the basis of the European Organization for Research and Treatment of Cancer-Mycosis Study Group definition criteria, and occurred in patients with leukemia. CDC-attributable clinical symptoms resolved with CST, which was started a mean of 33.8 days after antifungal therapy had been initiated. Fever and abdominal pain disappeared a median of 4-5 days, and serum fibrinogen and C-reactive protein levels returned to normal values within 14-30 days. The median duration of hospitalization after CST initiation was 8.8 days. Hepatosplenic microabscesses decreased or disappeared within a mean period of 107 days (range, 30-210 days). No relapses of CDC were observed during a median duration of follow-up of 6.5 years (range, 4-9 years). Conclusions. In children and adults who experience persistently symptomatic CDC despite ongoing receipt of antifungal therapy, CST involving a prednisone equivalent at a dosage of ⩾0.5 mg/kg per day for at least 3 weeks is associated with a prompt resolution of symptoms and of inflammatory response. These findings support the pathophysiological hypothesis that CDC belongs to the spectrum of fungus-related immune reconstitution inflammatory syndrome.
