Ferritin is a ubiquitous protein that plays a critical role in regulating intracellular iron homoeostasis by storing iron inside its multimeric shell. It also plays an important role in detoxifying potentially harmful free ferrous iron to the less soluble ferric iron by virtue of the ferroxidase activity of the H subunit. Although excess iron is stored(More)
PURPOSE The aim of this study was to evaluate the prognostic value of the WHO proposal, to assess the role of the main prognostic factors in myelodysplastic syndromes (MDSs) classified into WHO subgroups, and to estimate mortality (standardized mortality ratio [SMR]) and life expectancy in these groups as a basis for clinical decision making. PATIENTS AND(More)
BACKGROUND The aim of this study was to evaluate prognostic factors, treatments and outcome of invasive aspergillosis in patients with acute myeloid leukemia based on data collected in a registry. DESIGN AND METHODS The registry, which was activated in 2004 and closed in 2007, collected data on patients with acute myeloid leukemia, admitted to 21(More)
PURPOSE To assess the effect of erythropoietin (EPO) plus granulocyte-colony stimulating factor (G-CSF) treatment on survival and leukemic transformation in myelodysplastic syndrome (MDS). PATIENTS AND METHODS We compared the long-term outcome of patients with MDS treated with EPO plus G-CSF (n = 121) with untreated patients (n = 237) with MDS using(More)
May-Hegglin anomaly (MHA), Sebastian syndrome (SBS) and Fechtner syndrome (FTNS) are autosomal-dominant macrothrombocytopenias with Döhle-like leucocyte inclusions. These diseases are due to mutations of the MHY9 gene, encoding the heavy chain of non-muscle myosin IIA (NMMHC-A). We investigated the NMMHC-A localization in blood cells from eight MHA, SBS or(More)
MDS in patients treated for APL are rare events; we report a case that shows some traits that are unusual among therapyrelated stem cell disorders. A 51-year old woman presented in May 1997 with fatigue and dyspnea. Her peripheral blood cell count showed pancytopenia with 2% abnormal promyelocytes; coagulation tests showed signs of disseminated(More)
We describe eight patients (four children and four adults) with an acute lymphoblastic leukaemia (ALL) with cytoplasmic granules or inclusions. The incidence of this variant of acute leukaemia in our whole series of patients with ALL is 1.8%. The granules or inclusions were usually positive for aspecific esterases (ANAE) and/or acid phosphatase, and the(More)
PURPOSE The aims of this study were to identify the most significant prognostic factors in myelodysplastic syndromes (MDS) taking into account both their values at clinical onset and their changes in time and to develop a dynamic model for predicting survival and leukemic evolution that can be applied at any time during the course of the disease.

gamma-Interferon (IFN-gamma) has previously been found to induce monocytic differentiation in established leukemic cell lines, such as HL-60 and U937. The aim of the present study was to evaluate the differentiative effect of highly purified recombinant (r)IFN-gamma on fresh bone marrow cells from patients with acute nonlymphocytic leukemia (n = 11) or(More)
