We report a case of disseminated Scedosporium apiospermum infection in a neutropenic patient with acute myeloid leukemia. Due to progression of the mycosis after 7 days of amphotericin B lipid complex therapy and to high susceptibility of the mold to voriconazole in vitro, the patient was treated with intravenous voriconazole. After a few days of therapy, fever disappeared and skin lesions improved. However, the patient died after 1 month due to intestinal bleeding. Despite a negative outcome, this case seems to indicate a promising role for voriconazole in the treatment of S. apiospermum infections.

Complete remission was observed in an adult patient with acute myelogenous leukemia after minimal monochemotherapy. Remission occurred after a severe febrile pneumonia and was accompanied by cytogenetic and molecular remission. The hypothesis of spontaneous remission was raised, even if a high sensitivity to low-dose cytostatics cannot be excluded. Such spontaneous complete remissions, often associated with bacterial infections and blood transfusions, are extremely rare, and are usually of short duration. Previous cases are summarized, and the role of etiologic factors is discussed.

A serum against human lymphoblastic leukemia cells was obtained inoculating rabbits. We studied the specificity of the serum before and after particular absorptions in various clinical conditions. The serum was cytotoxic against many cases of acute lymphoblastic leukemia, against continuously cultured Burkitt’s lymphoma cells and against chronic myelogenous leukemia in blast crisis. On the contrary, the serum was not cytotoxic against lymphocytes of normal donors, acute lymphoblastic leukemia in remission and other lymphoproliferative disorders.

To evaluate the addition of a third drug to standard induction chemotherapy in patients with MDS-AML, 23 patients (males/females 13/10, median age 54.3 years, range 24-74 years, median MDS duration 9.8 months, range 2-39 months) who received a standard 2-drugs induction were compared with 23 patients (males/females 11/12, median age 45.6 months, range 21-60 years, median MDS duration 8.3 months, range 2-29 months) who received an intensified 3-drugs induction with etoposide. CR rate, median CR duration and median OS were similar in both groups (48% vs 56%, 4.8 vs 5.9 months, 6.5 vs 7.0 months respectively). Among responding patients, all but one, who underwent allogeneic bone marrow transplantation, relapsed. In conclusion, addition of a third drug (etoposide) does not seem to significantly improve the poor prognosis of MDS-AML patients.
