Özet
Myelodysplastic syndrome (MDS) is a clonal disease of the bone marrow characterized by abnormal hematopoiesis and cytopenias. It has been shown that abnormal cytokine production together with apoptosis are major contributors to the cytopenias associated with the disorder. As the interaction of cytokines plays a role in the pathogenesis, suppression of the cytokine production by the administration of the combination of pentoxyfilline, ciprofloxacin, and dexamethasone (PCD combination) has resulted in the correction of at least some aspects of the cytopenias in the majority of patients and in complete hematologic remission in a small percentage. The aminothiol prodrug amifostine, a compound to protect tissues from cytotoxic drugs and radiotherapy has been found to stimulate proliferation of normal hematopoesis and suppress apoptosis in patients with MDS. In this study we report the results of combination therapy of amifostine and PCD in 12 patients with MDS and acute myeloid leukemia (AML). Amifostine was given in a dose of 200 mg/m2, as an i.v. infusion administered in 10 min, three times a week; pentoxyfilline 2400 mg/day, (3 × 800 mg) p.o.; ciprofloxacine, 1 g/day p.o.; dexamethasone 4·5 mg/day p.o. We achieved 66% response rate in our patients. In some cases responses were achieved in only thrombocytopenia or anemia whereas in others responses were achieved in multiple series. As a result it was found that amifostine + PCD combination may be beneficial in reversing cytopenias in the treatment of MDS and AML and is worth further study.
