RESUMO
In order to establish whether long-term itraconazole therapy can affect adrenal or testicular function, the adrenal response to corticotrophin and testosterone was evaluated by radioimmunoassay in 15 patients undergoing treatment for chromoblastomycosis. Mean cortisol and testosterone concentrations were 12.4 microg/dL and 454 ng/dL respectively at baseline and 15.4 microg/dL and 480 ng/dL respectively after 12.4+/-5.2 months of treatment with itraconazole (200-400 mg daily). Results were analysed using Student's t-test. There was no clinical or laboratory evidence of steroidogenic or androgenic impairment.

The efficacy and tolerability of itraconazole in chromoblastomycosis due to Fonsecaea pedrosoi were evaluated in a non-comparative open clinical trial in 19 Brazilian patients with histopathologically and mycologically proven active chromoblastomycosis. Patients were classified in terms of severity and received itraconazole at the dosage of 200 to 400 mg per day until previously described criteria of cure have been reached. Clinical, mycologic, histopathologic, and laboratory evaluations were performed before, during, and after therapy. The plasma levels of itraconazole and the in vitro susceptibility of the isolates were determined in 15 cases. Clinical and biologic cure were achieved by eight patients (42%) having mild to moderate disease, after a mean duration of therapy of 7.2 months (3.2-29.6 months). Sterile scarred lesions were observed in a post-therapy follow-up lasting on average 9.6 months that was carried out in this subgroup. Clinical cure alone occurred after a mean period of 25.1 months of treatment (16-30.5 months) in seven patients (36%) with moderate to severe disease. Finally, clinical improvement was obtained in four patients (21%) with severe lesions after a mean treatment time of 17.6 months (10.7-22.5 months). All patients responded favorably to itraconazole therapy. No significant side effects nor biochemical alteration during this trial were important enough to interrupt the treatment. Our results support those of previous trials, suggesting that itraconazole is an effective compound against chromoblastomycosis due to Fonsecaea pedrosoi.
