The terminal complement inhibitor eculizumab was recently shown to be effective and well tolerated in patients with paroxysmal nocturnal hemoglobinuria (PNH). Here, we extended these observations with results from an open-label, non-placebo-controlled, 52-week, phase 3 clinical safety and efficacy study evaluating eculizumab in a broader PNH patient(More)
Hydroxyurea (HU) is frequently given as treatment for myelofibrosis (MF), but data on its efficacy and tolerability are scarce. The results of HU therapy were evaluated in 40 patients with hyperproliferative manifestations of primary (n = 32), post-polycythemia vera (n = 6), or post-essential thrombocythemia (n = 2) myelofibrosis. Median interval between(More)
The behavior of classic Hodgkin lymphoma (cHL) is determined by both the intrinsic features of the tumor cells and the characteristics of the microenvironment, making the analysis of entire lymph nodes an effective approach to understanding the disease. We examined the influence of our previously reported 25-microRNA signature for cHL on clinical outcome in(More)
OBJECTIVE To compare T-cell reconstitution in two groups of patients submitted to allogeneic stem cell transplantation (SCT): those receiving reduced-intensity conditioning (RIC, n = 24) and those receiving myeloablative conditioning (MA, n = 27). METHODS Fifty-one consecutive patients undergoing SCT were evaluated. Serial assessments of lymphocyte(More)
The association between seven polymorphisms in the genes hOCT1 and MDR1, encoding for imatinib transporter proteins, and the response to imatinib 400mg/daily was investigated in 65 patients newly diagnosed with chronic-phase chronic myeloid leukemia. The AA genotype at the rs6935207 hOCT1 polymorphic locus was not detected in patients with inadequate(More)
MicroRNAs (miRNAs) are negative regulators of gene expression that play an important role in hematopoiesis and tumorigenesis. We analyzed miRNA expression in classic Hodgkin lymphoma (cHL) and the influence of Epstein-Barr virus (EBV) infection on the miRNA expression profiles. The expression of 157 miRNAs in lymph nodes from 49 cHL patients and 10 reactive(More)
In Paroxysmal nocturnal haemoglobinuria (PNH), pregnancy is associated with increased maternal and foetal complications to such an extent that the condition has been considered relatively contra-indicated in PNH. Eculizumab has revolutionized the treatment of PNH. We evaluate its use in pregnancy to date. We report on seven patients exposed to eculizumab at(More)
MicroRNAs (miRNAs) are negative regulators of expression of genes involved in hematopoiesis. The present study sought to link hematopoiesis-relevant miRNAs with myelodysplastic syndromes (MDS) and MDS progression to acute myeloid leukemia (AML). We assessed 25 mature miRNAs in total RNA from bone marrow (BM) and peripheral blood (PB) of 25 newly diagnosed(More)
Evidence is presented showing that a protein tyrosine phosphatase different from CD45 is present on the membrane of human hematopoietic cells. The molecule recognized by the monoclonal antibody 143-41, which has been classified as CD148 in the VI International Workshop on Leukocyte Differentiation Antigens, was immunopurified and sequenced. The sequence(More)
