 Plasma concentrations of the most potent megakaryocytopoietic cytokines, thrombopoietin (TPO) and interleukin-6 (IL-6), and the platelet activation marker P-selectin were evaluated in 24 patients with autoimmune thrombocytopenic purpura (ATP) who responded to conventional steroid treatment, at diagnosis and after steroid-induced recovery. Baseline TPO(More)
 Leukemic infiltration of the prostate is unusual. Acute retention of urine as the first clinical manifestation of an unsuspected, asymptomatic chronic lymphocytic leukemia (CLL) is found only in sporadic case reports. This report documents a case of CLL in a 65-year-old man presenting with acute urinary retention. The literature pertinent to this topic is(More)
OBJECTIVE The prominent functions of the local renin-angiotensin system (RAS) in primitive hematopoiesis further support the hypothesis that local autocrine bone marrow RAS could also be active in neoplastic hematopoiesis. The aim of this study is to examine critical RAS elements in normal CD34+ hematopoietic stem cells and multiple myeloma (MM)-related(More)
Paroxysmal nocturnal hemoglobinuria (PNH) is characterized by the triad of intravascular hemolysis, venous thrombosis, and cytopenia. Treatment of PNH is generally supportive. Bone marrow transplantation is the only curative therapy for PNH, but is associated with significant morbidity and mortality. Herein, we present a patient with PNH that received(More)
UNLABELLED Additional chromosomal abnormalities in acute myelogenous leukemia have been identified as one of the most important prognostic factors. Favorable chromosomal changes such as t(8;21), inv(16), and t(15;17) are associated with higher rates of complete remission and event-free survival. Translocation (15;17) characterizes acute promyelocytic(More)
OBJECTIVES Reactive haemophagocytic syndrome (RHS) is a hyperinflammatory disorder often occurring in the background of several disorders such as infections, malignancies, and rheumatic diseases. Recently, a score known as the HScore was developed for the diagnosis of RHS. In the original study, most of the patients had underlying haematological malignancy(More)
Chronic myeloid leukemia (CML) is genetically characterized by the presence of the reciprocal translocation t(9;22) with the formation of Philadelphia (Ph) chromosome. Sometimes, the Ph translocation is generated by variant rearrangements. The prognostic impact of the variant translocations is still controversial. Among the 180 patients with Ph-positive CML(More)
Severe aplastic anemia (SAA) has an aggressive clinical course and represents a “difficult-to-treat” situation with current medications [1]. Eltrombopag is a c-mpl receptor agonist oral thrombopoietin-mimetic drug, mainly active in immune thrombocytopenic purpura (ITP) [2]. Single-agent oral eltrombopag produced hematological responses in 11 of 25 cases of(More)
OBJECTIVE Many studies reported an improved prognosis in patients with Burkitt's lymphoma obviating the need of stem cell transplantation. However, prognosis of the advanced disease [i.e. Burkitt's cell leukemia (BCL)] has not been reported with current treatment modalities except for a few prospective trials. The aim of this study is to compare the(More)
We studied retrospectively the factors affecting the product quality in 459 donor granulocyte apheresis procedures from 420 donors for 71 neutropenic patients from 2004 to 2010 in a single center. The counts of the granulocyte and platelet collected were measured to evaluate the product quality. The data was analyzed to determine a possible relationship(More)
