Diagnosis and management of immune thrombocytopenic purpura (ITP) remain largely dependent on clinical expertise and observations more than on evidence derived from clinical trials of high scientific quality. One major obstacle to the implementation of such studies and in producing reliable meta-analyses of existing data is a lack of consensus on(More)
Rituximab, an anti-CD20 monoclonal antibody, has been used to treat autoimmune disorders such as idiopathic thrombocytopenic purpura (ITP). However, its mechanisms of action as well as the effects on cellular immunity remain poorly defined. We investigated the changes of different peripheral blood T-cell subsets, the apoptosis profile, as well as the(More)
Whether the eradication of Helicobacter pylori infection can increase the platelet count in patients with immune thrombocytopenic purpura (ITP) is still a controversial issue. To provide evidence-based guidance, we performed a systematic review of the literature published in English, selecting articles reporting 15 or more total patients. We identified 25(More)
The role of glycosylated recombinant human granulocyte colony-stimulating factor (G-CSF) in the induction treatment of older adults with acute myeloid leukemia (AML) is still uncertain. In this trial, a total of 722 patients with newly diagnosed AML, median age 68 years, were randomized into 4 treatment arms: (A) no G-CSF; (B) G-CSF during chemotherapy; (C)(More)
OBJECTIVE Rituximab, a chimeric anti-CD20 monoclonal antibody, has been shown to be quite effective in the treatment of immune disorders resulting from autoantibodies. We prospectively studied the long-term effects of rituximab in 10 patients with anti-neutrophil cytoplasmic antibody (ANCA)-positive vasculitis refractory to conventional therapy (n=3) or in(More)
BACKGROUND The long-term outcome of individuals with mild degrees of thrombocytopenia is unknown. METHODS AND FINDINGS In a prospective study conducted between August 1992 and December 2002, 260 apparently healthy individuals with incidentally discovered platelet counts between 100 x 10(9)/l and 150 x 10(9)/l were monitored for 6 mo to determine whether(More)
The treatment of choice in steroid-resistant immune thrombocytopenia is still controversial due to the recent advent of new drugs (anti-CD20 antibodies and thrombopoietin mimetics) that have encouraged a generalized tendency to delay splenectomy. Consequently, it is extremely importance to define the efficacy and safety of splenectomy in the long term. We(More)
In a previous publication on new terminology, definitions, and outcome criteria for immune thrombocytopenia (ITP), the International Working Group (IWG) on ITP acknowledged that response to treatment should consist of clinically meaningful end points such as bleeding manifestations and that platelet count may not be the ideal parameter for capturing the(More)
In vitro studies suggest that all-trans retinoic acid (ATRA) synergizes with erythropoietin (EPO) for the stimulation of hematopoiesis in patients with myelodysplastic syndrome (MDS). A clinical trial was performed to evaluate whether a combination of these agents was effective in relieving the cytopenias associated with MDS. Twenty-seven patients with low-(More)
In a recent issue of Blood we reported that rituximab anti-CD20 monoclonal antibody is an active drug in adults with chronic idiopathic thrombocytopenic purpura (ITP), that it is able to induce long-lasting responses, and that in all responders a rise of the platelet count occurs early during treatment, usually right after the first antibody administration.(More)
