In a 64-year-old man suffering from hypoblastic myelodysplastic syndrome a secondary acute myeloid leukaemia developed. After induction chemotherapy with resulting partial remission he received an allogenic (related) peripheral blood stem cell transplantation conditioned with 2 Gy total body irradiation. After haematopoietic reconstitution chest pain and dyspnoea appeared. Computer tomography revealed diffuse bilateral infiltrates which were considered to be suspicious for an invasive pulmonary aspergillosis of the left upper lobe. Respiratory and circulatory insufficiency occurred. In bronchoalveolar lavage fluid Aspergillus antigen was detected. In addition, Aspergillus flavus was isolated on Sabouraud-dextrose agar. Ambisome (liposomal encapsulated amphotericin B) was applied in high dosages. On the skin of the sides and the back five livid red stained nodular lesions with haemorrhagic infarctions appeared. Pathohistologically, both in PAS (periodate acid Schiff) and Grocott-Gomori staining conglomerates of septated hyphae were detected in corium and subcutis. In addition, Aspergillus flavus grew from skin tissue. Despite antifungal treatment the patient died from Aspergillus pneumonia and generalized aspergillosis with dissemination to heart, brain, and skin.

Invasive fungal infection remains the most common cause of infectious death in acute leukemia. In this open-label, randomized study, we compared the efficacy and safety of caspofungin with that of intravenous itraconazole for antifungal prophylaxis in patients undergoing induction chemotherapy for acute myelogenous leukemia or myelodysplastic syndrome. Of 200 patients, 192 were evaluable for efficacy (86 for itraconazole, 106 for caspofungin). Duration of prophylaxis (median, 21 days [range, 1 to 38 days]), demographics, and prognostic factors were similar in both groups. Ninety-nine patients completed antifungal prophylaxis without developing fungal infection (44 [51%] with itraconazole, 55 [52%] with caspofungin). Twelve patients developed documented invasive fungal infections, five in the itraconazole group (four with candidemia and one with Aspergillus pneumonia), and seven in the caspofungin group (two with candidemia, two with disseminated trichosporon species, two with Aspergillus pneumonia, and one with disseminated Fusarium spp). Two patients in the itraconazole group and four in the caspofungin group died of fungal infection (P = 0.57). Grade 3 to 4 adverse event rates were comparable between groups; the most common event in both was reversible hyperbilirubinemia. No evidence of cardiovascular toxicity from intravenous itraconazole was noted among patients older than 60. In conclusion, intravenous itraconazole and caspofungin provided similar protection against invasive fungal infection during induction chemotherapy, and both drugs were well tolerated.
