Paroxysmal nocturnal haemoglobinuria (PNH) is an acquired clonal stem cell disorder characterized by intravascular haemolysis, venous thrombosis, marrow hypoplasia, frequent episodes of infection, and rarely leukaemic conversion. At the cellular level, PNH is characterized by the decrease or absence of glycosylphosphatidylinositol (GPI)-anchored molecules,(More)
 Inflammatory pseudotumor of the spleen is a benign tumorous lesion of unknown etiology and pathogenesis that has been described in only a few cases in the literature. Recognition of this rare entity is important, as the clinical manifestations and imaging features could be indistinguishable from a lymphoproliferative disorder or another malignancy of the(More)
BACKGROUND/AIM The hypomethylating agent 5-azacytidine has been the standard-of-care for patients with higher-risk myelodysplastic syndrome (MDS) during the past few years. Its efficacy has been proven in large clinical trials, and its safety has been shown to be superior to that of conventional treatments. PATIENTS AND METHODS We conducted a(More)
Fc-γ RIIA (CD32), a member of the family of Fc-γ receptors, participates in the phagocytosis of bound to antibody antigens. The effectiveness of this function varies for its several haplotypes, and it participates in the pathogenesis of viral infections, according to recent studies. The genetic locus of Fc-γ RIIA consists of two allelic genes: 131-Arg(More)
Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired clonal disorder characterized by a decrease or absence of glycosylphosphatidylinositol (GPI)-anchored molecules such as CD55 and CD59 from the surface of affected cells, resulting in intravascular hemolysis, cytopenia, and venous thrombosis. A PNH-like phenotype has been detected in various(More)
INTRODUCTION Paroxysmal nocturnal hemoglobinuria is an acquired clonal stem cell disorder characterized by the decrease or absence of glycosylphosphatidylinositol-anchored molecules from the surface of the affected cells, such as CD55 and CD59, resulting in chronic intravascular hemolysis, cytopenia and increased tendency to thrombosis. PNH-phenotype has(More)
CD55 and CD59 are complement regulatory proteins that are linked to the cell membrane via a glycosyl-phosphatidylinositol anchor. They are reduced mainly in paroxysmal nocturnal hemoglobinuria (PNH) and in other hematological disorders. However, there are very few reports in the literature concerning their expression in patients with acute leukemias (AL).(More)
Low absolute lymphocyte count (ALC) to absolute monocyte count (AMC) ratio (ALC/AMC) is an independent prognostic factor in Hodgkin lymphoma (HL), but different cutoffs (1.1, 1.5, and 2.9) have been applied. We aimed to validate the prognostic significance of ALC/AMC in 537 homogenously treated (doxorubicin, bleomycin, vinblastine, and dacarbazine or(More)
Myelofibrosis is not frequent in systemic lupus erythematosus (SLE). A review in the literature reveals that the co-incidence is rather rare since there are only a few papers reporting this combination. The female patient described hereby, presented with thrombocytopenia; following investigation, the diagnosis of SLE was established and bone marrow(More)
