ADAMTS13, von Willebrand Factor, Platelet Microparticles, Factor VIII, and Impact of Somatic Mutations in the Pathogenesis of Splanchnic Vein Thrombosis Associated with BCR-ABL-Negative Myeloproliferative Neoplasms.

Background: Myeloproliferative neoplasms (MPNs) are often associated with splanchnic vein thrombosis (SVT). Not all the factors involved in the thrombotic tendency are currently known.

Objectives: This study aims to evaluate a possible association between ADAMTS13, von Willebrand factor (VWF), platelet microvesicles (MV), and factor VIII activity (FVIII:C) with thrombotic events in MPN patients.

Platelet Microvesicles, Inflammation, and Coagulation Markers: A Pilot Study.

Background: Platelet "Microvesicles" (MVs) are studied for their role in blood coagulation and inflammation. The study aimed to establish if MVs are related to age, plasma levels of inflammation, coagulation, and fibrinolysis markers in healthy individuals.

Methods: We prospectively enrolled volunteers aged over 18 years.

Ferric Carboxymaltose and Erythropoiesis-Stimulating Agent Treatment Reduces the Rate of Blood Transfusion in Refractory Anemia.

: Erythropoiesis-stimulating agents (ESAs) are used to treat refractory anemia (RA). Guidelines suggest iron supplementation for unresponsive patients, regardless of iron deficiency. The primary aim of this study was to evaluate the effect of iron supplementation with ferric carboxymaltose (FCM) on the reduction of red blood cell transfusion (RBCT) rate in transfusion-dependent RA patients.

Incidence of Venous Thromboembolism in Multiple Myeloma Patients across Different Regimens: Role of Procoagulant Microparticles and Cytokine Release.

Introduction: Multiple myeloma (MM) is characterized by a high prevalence of thrombotic complications. Microvesicles (MVs) are small membrane vesicles released from activated cells, and they may potentially contribute to thrombosis. Methods: We have evaluated the plasma levels of MVs and cytokines (IL-10, IL-17, and TGF-β in MM and Watch and Wait Smoldering MM (WWSMM) from patients and related them to thrombotic complications.

Risk-tailored treatment of splenic marginal zone lymphoma.

Splenic marginal zone lymphoma (SMZL) is a rare lymphoproliferative disease involving B-cells and affecting elderly patients. SMZL plague peripheral blood and bone marrow, spleen. Lymph nodes are generally spared.

Does Outcome/Survival of Patients With Myelodysplastic Syndromes Should Be Predicted by Reduced Levels of ADAMTS-13? Results From a Pilot Study.

Introduction: Von Willebrand factor (vWF) cleaving protease ADAMTS-13 has a key role for maintaining normal size of vWF. A deficiency or dysfunction of vWF cleaving protease is associated with ultra large vWF multimers and thrombotic microangiopathy. Patients with cancers have reduced levels of vWF cleaving protease.

Management of anemia in low-risk myelodysplastic syndromes treated with erythropoiesis-stimulating agents newer and older agents.

The myelodysplastic syndromes (MDSs) are clonal hematopoietic stem cell disorders. The International Prognostic Score System (IPSS) groups MDS in lower-risk (IPSS low and intermediate-1) and higher-risk disease (IPSS intermediate-2 and high). AML transformation is the main concern in higher-risk MDS, while anemia and transfusion dependency represent the major issues for low-risk MDS patients.

The impact of anaemia, transfusion dependency, comorbidities and polypharmacy in elderly patients with low-risk myelodysplastic syndromes.

Myelodysplastic syndromes (MDS) are heterogeneous clonal disorders ranging from indolent conditions with a near-normal life expectancy to forms approaching acute myeloid leukaemia. Comorbid conditions have rarely been systematically studied among patients with MDS. Older age per se has a negative impact on survival of MDS patients, in particular of those with lower risk.

First-line treatment with bendamustine and rituximab, in patients with intermediate-/high-risk splenic marginal zone lymphomas.

Splenic marginal zone lymphomas (SMZLs) are rare indolent B cell neoplasms that affect the spleen, bone marrow, and blood. Although they have an indolent course in the majority of patients, who have a median survival of 8-10 years, ∼ 30% may experience a worse outcome. The prognostic criteria of progression are lymph node and extra-nodal involvement, high lymphocyte counts, anaemia, and thrombocytopenia.

Personalized treatment strategies for elderly patients with myelodysplastic syndromes.

Myelodysplastic syndromes (MDS) are a heterogeneous group of hematopoietic disorders characterized by ineffective hematopoiesis and peripheral cytopenia, and their possible transformation into acute myeloid leukemia (AML). They typically affect the elderly but, when making treatment decisions, considering chronological age may be insufficient because it poorly correlates with patient frailty: the challenge is to select the optimal treatment in these patients by balancing efficacy and toxicity. Areas covered: This review discusses the rationale for and methods of personalizing the treatment of elderly MDS patients.

High prevalence of heparin induced thrombocytopenia with thrombosis among patients with essential thrombocytemia carrying V617F mutation.

Arterial and venous complications are major causes of morbidity and mortality in myeloproliferative neoplasms (MPNs). MPNs patients, frequently receive heparin. Heparin-induced thrombocytopenia (HIT) is a rare but potentially life-threatening complication resulting in a severe acquired thrombophilic condition.

Dose-Reduced Versus Standard Conditioning Followed by Allogeneic Stem-Cell Transplantation for Patients With Myelodysplastic Syndrome: A Prospective Randomized Phase III Study of the EBMT (RICMAC Trial).

Purpose To compare a reduced-intensity conditioning regimen (RIC) with a myeloablative conditioning regimen (MAC) before allogeneic transplantation in patients with myelodysplastic syndrome (MDS) within a randomized trial. Patients and Methods Within the European Society of Blood and Marrow Transplantation, we conducted a prospective, multicenter, open-label, randomized phase III trial that compared a busulfan-based RIC with MAC in patients with MDS or secondary acute myeloid leukemia. A total of 129 patients were enrolled from 18 centers.

Biosimilar epoetin alfa increases haemoglobin levels and brings cognitive and socio-relational benefits to elderly transfusion-dependent multiple myeloma patients: results from a pilot study.

Anaemia is a complication reported in up to 70% of the multiple myeloma patients (MM), with remarkable clinical, cognitive and socio-relational consequences. Anaemia relates to the course of MM, normalizing in patients during remission and reappearing in relapsing/non-responding patients. In a pilot study with 31 patients with MM and transfusion-dependent anaemia, we evaluated the effects of Binocrit (biosimilar epoetin alfa) on transfusions, haemoglobin levels, mental status (mini-mental state evaluation) and the patients' social-relational functioning and quality of life (QoL).

High rate of hepatitis B viral breakthrough in elderly non-Hodgkin lymphomas patients treated with Rituximab based chemotherapy.

Background: Rituximab-containing chemotherapies are offered to elderlies for treatment of non-Hodgkin lymphomas (NHL). From 0.7 to 27% of patients with "resolved" HBV infection develop HBV reactivation and related hepatitis during Rituximab-containing chemotherapies.

Bendamustine and Rituximab, as First Line Treatment, in Intermediate, High Risk Splenic Marginal Zone Lymphomas of Elderly Patients.

Background: Splenic marginal zone lymphoma (SMZL) is a chronic B-cell lymphoproliferative disorder, comprising less than 2% of non-Hodgkin's lymphomas, and affecting mainly middle-aged and elderly patients with a median survival of >10 years. The typical clinical features of SMZL include splenomegaly. Treatment should be patient-tailored and can range from a 'watchful waiting' approach for asymptomatic patients without cytopenias to surgery, localized radiation therapy or immuno/chemotherapies.

Laboratory and clinical risk assessment to treat myelodysplatic syndromes.

Myelodisplastic syndromes (MDS) are heterogeneous myeloid disorders characterized by peripheral cytopenias and increased risk of transformation into acute myelogenous leukemia (AML). MDS are generally suspected in the presence of cytopenia on routine analysis and the evaluation of bone marrow cells morphology and cellularity leads to correct diagnosis of MDS. The incidence of MDS is approximately five cases per 100,000 people per year in the general population, but it increases up to 50 cases per 100,000 people per year after 60 years of age.

Salvage therapy with bortezomib and dexamethasone in elderly patients with relapsed/refractory multiple myeloma.

Bortezomib-dexamethasone (bort-dex) is effective for relapsed/refractory (R/R) multiple myeloma, but few data are available for elderly patients. The aim of this study was to evaluate efficacy and toxicity of bort-dex in elderly R/R MM patients. We evaluated 81 R/R MM patients treated with bort-dex.

Biosimilar epoetin in elderly patients with low-risk myelodysplastic syndromes improves anemia, quality of life, and brain function.

The myelodysplastic syndromes (MDS) are a group of clonal hematopoietic disorders characterized by bone marrow failure and a risk of progression to acute myeloid leukemia (AML). Anemia affects the course of disease, quality of life (QOL), and cognitive function of MDS patients. Erythroid-stimulating agents (ESAs) are effective; however, not all patients respond to ESAs.

Cooperation between pathologists and clinicians allows a better diagnosis of Philadelphia chromosome-negative myeloproliferative neoplasms.

As no specific genetic lesions have yet been identified, the diagnosis of Philadelphia chromosome-negative myeloproliferative neoplasms is based on a simultaneous evaluation of the clinical, morphological and molecular features defined by the updated WHO classification, which allow most cases of full-blown disease to be classified. Nevertheless, about 10-15% of the patients have unclassifiable myeloproliferative neoplasms, most of whom are in the prodromal (early) phase of disease and identified by the presence of the JAK2 mutation, but lack the complete phenotype required by the WHO classification. The detection of these prodromal phases is extremely important in order to prevent dramatic thrombo-hemorrhagic complications and improve prognosis.

Single-agent Smac-mimetic compounds induce apoptosis in B chronic lymphocytic leukaemia (B-CLL).

Defective apoptosis is a hallmark of the progression of B chronic lymphocytic leukaemia (B-CLL). Smac-mimetics have been shown to induce apoptosis in several tumours. We describe the in vitro pro-apoptotic activity and regulation of the molecular pathway induced by new Smac-mimetics in B-CLL.
