Pleural effusion and molecular response in dasatinib-treated chronic myeloid leukemia patients in a real-life Italian multicenter series.

Pleural effusion (PE) represents the leading cause of dasatinib (DAS) discontinuation. However, the pathogenic mechanism of this adverse event (AE) is unknown and its management unclear. We investigated if a DAS dose reduction after the first PE would prevent the recurrence of this AE.

Ponatinib as a Valid Alternative Strategy in Patients with Blast Crisis-Chronic Myeloid Leukemia Not Eligible for Allogeneic Stem Cells Transplantation and/or Conventional Chemotherapy: Report of a Case.

Currently, imatinib and dasatinib are the only tyrosine-kinase inhibitors approved in the US and Europe for the treatment of blast crisis of chronic myeloid leukemia (BC-CML) at diagnosis, while ponatinib is the only inhibitor used in patients bearing T315I mutation. Here we report the case of a 61-year-old man diagnosed with B-cell lymphoid BC-CML, initially treated with imatinib 800 mg day and then with dasatinib 140 mg day because of intolerance. A complete cytogenetic response (CCyR) was achieved at three months; however, three months later a relapse was observed, and the T315I mutation was detected.

Relationship between atrial fibrillation and cognitive decline in individuals aged 80 and older.

Background: Atrial fibrillation (AF) and dementia are largely prevalent and incident in progressively older subjects, suggesting a link between the two conditions. While in the general population there are several findings supporting a causal relationship between AF and dementia, it is unclear whether or not this association is still present in individuals aged 80 and older.

Results: So far, the few studies that analysed this issue did not provide enough evidence supporting the causative role of AF in increasing the risk of cognitive decline or dementia in patients aged 80 and older.

An unusual type of myeloid sarcoma localization following myelofibrosis: A case report and literature review.

Myeloid Sarcoma (MS) is a rare malignancy that can present as an isolated disease or more frequently in association with or following acute myeloid leukemia or other myeloid neoplasms and rarely following myelofibrosis. Since molecular pathogenesis and prognostic factors of MS are not well understood, its prognosis remains poor even in the era of novel agents and target therapies. We report the case of a patient with MS following myelofibrosis with multiple subcutaneous, cutaneous and muscle localizations; the latter has been reported in the literature as anecdotal.

The relationship between idiopathic cytopenias/dysplasias of uncertain significance (ICUS/IDUS) and autoimmunity.

This review examines the several lines of evidence that support the relationship between myelodysplasia and autoimmunity, i.e. their epidemiologic association, the existence of common immune-mediated physiopathologic mechanisms, and the response to similar immunosuppressive therapies.

Incidence of second primary malignancies and related mortality in patients with imatinib-treated chronic myeloid leukemia.

The majority of patients with chronic myeloid leukemia are successfully managed with life-long treatment with tyrosine kinase inhibitors. In patients in chronic phase, other malignancies are among the most common causes of death, raising concerns on the relationship between these deaths and the off-target effects of tyrosine kinase inhibitors. We analyzed the incidence of second primary malignancies, and related mortality, in 514 chronic myeloid leukemia patients enrolled in clinical trials in which imatinib was given as first-line treatment.

Socioeconomic burden of participation in clinical trials in patients with myeloproliferative neoplasms.

Objective: To determine the financial and psycho-social impact of participation in clinical trials of patients with BCR/ABL-negative myeloproliferative neoplasms (MPN).

Methods: An international, observational cross-sectional study was performed in 143 consecutive MPN patients (51% myelofibrosis, 36% polycythemia vera, 13% essential thrombocythemia), 68% from Italy, 17% from USA, and 15% from Spain.

Results: Thirty-five percent of patients reported having spent more money during the trial than in previous treatments and 21% having missed more workdays.

CD18 promoter methylation is associated with a higher risk of thrombotic complications in primary myelofibrosis.

Unlabelled: Morbidity and mortality of BCR-ABL1-negative myeloproliferative neoplasm (MPN) patients are influenced by disease-related hemostatic complications, mostly of thrombotic nature. The pathogenesis of thrombosis is multifactorial: in particular, it has been demonstrated that a deregulated expression of Mac1 (also known as surface receptor integrin CD18/CD11b) by leukocytes has a role in favoring platelets' activation in MPN patients. Based on these data, we investigated the epigenetic status of CD18/CD11b in 78 primary myelofibrosis (PMF) patients to explore any possible association between the epigenetic profiles of these two genes and thrombotic risk.

The combination of pharmacogenetic and pharmacokinetic analyses to optimize clomipramine dosing in major depression: a case report.

What Is Known And Objective: Polymorphisms in cytochrome P450 2D6 and 2C19 can lead to interindividual differences in drug plasma concentrations, affecting clomipramine efficacy. Pharmacokinetic and pharmacogenetic analyses may improve drug therapy.

Case Summary: We report the case of a depressed woman requiring higher doses than standard of clomipramine.

Imatinib and polypharmacy in very old patients with chronic myeloid leukemia: effects on response rate, toxicity and outcome.

Background: About 40% of all patients with chronic myeloid leukemia are currently old or very old. They are effectively treated with imatinib, even though underrepresented in clinical studies. Furthermore, as it happens in the general population, they often receive multiple drugs for associated chronic illnesses.

Tie2 Expressing Monocytes in the Spleen of Patients with Primary Myelofibrosis.

Primary myelofibrosis (PMF) is a Philadelphia-negative (Ph-) myeloproliferative disorder, showing abnormal CD34+ progenitor cell trafficking, splenomegaly, marrow fibrosis leading to extensive extramedullary haematopoiesis, and abnormal neoangiogenesis in either the bone marrow or the spleen. Monocytes expressing the angiopoietin-2 receptor (Tie2) have been shown to support abnormal angiogenic processes in solid tumors through a paracrine action that takes place in proximity to the vessels. In this study we investigated the frequency of Tie2 expressing monocytes in the spleen tissue samples of patients with PMF, and healthy subjects (CTRLs), and evaluated their possible role in favouring spleen angiogenesis.

Erdheim-Chester Disease With Multiorgan Involvement, Following Polycythemia Vera: A Case Report.

Erdheim-Chester disease is a rare form of non-Langerhans cell histiocytosis characterized by the migration and infiltration of lipid-laden CD68, CD1a and S100 histiocytes to various target organs, which leads to the disruption of physiological tissue architecture and reactive fibrosis, and thus impairs organ function.We describe the first case of a patient with Erdheim-Chester disease with multiorgan involvement developed after 6 years from polycythemia vera diagnosis. During the follow-up, an abdominal ultrasound scan revealed the presence of dense, bilateral perinephric infiltration.

Predictors of clinical events occurring during hospital stay among elderly patients admitted to medical wards in Italy.

Background: Clinical events occurring during hospital stay are independent predictors of prolonged hospitalization, in-hospital mortality and readmission among elderly patients admitted to medical wards.

Purpose: To identify predictors of intercurrent clinical events (ICE) during hospital stay among the main demographic, functional and clinical characteristics assessed at hospital admission in a multicenter sample of elderly inpatients in Italy.

Methods: This observational prospective cohort study was conducted in 66 internal and geriatric medicine hospital wards in 2010.

Active subcutaneous calcinosis demonstrated by fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography in a case of limited cutaneous systemic sclerosis.

Systemic sclerosis (SSc) is a rheumatic autoimmune disease of unknown origin causing fibrosis of the skin and the internal organs. The limited cutaneous variant is the most common subtype of SSc, and it is predominantly characterized by skin and soft-tissues involvement. A 72-year-old woman, who had been diagnosed with the limited cutaneous form of SSc 16 years before, underwent fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) examination due to unexplained weight loss and recent onset of fatigue and joint pain.

Anagrelide and Mutational Status in Essential Thrombocythemia.

Background: Anagrelide is an orally active, quinazolone-derived, platelet-lowering agent that acts by blocking megakaryocyte maturation and polyploidization as well as proplatelet formation, and is currently indicated for second-line treatment of high-risk patients with essential thrombocythemia (ET) in Europe. In recent years various clinical trials have confirmed the safety and efficacy of this drug in ET, with some also considering Janus kinase 2 (JAK2) mutational status, but have not confirmed the impact that the other driver mutations, i.e.

Ndufc2 Gene Inhibition Is Associated With Mitochondrial Dysfunction and Increased Stroke Susceptibility in an Animal Model of Complex Human Disease.

Background: The genetic basis of stroke susceptibility remains to be elucidated. STR1 quantitative trait locus (STR1/QTL) was identified on rat chromosome 1 of stroke-prone spontaneously hypertensive rat (SHRSP) upon Japanese-style stroke-permissive diet (JD), and it contributes to 20% of the stroke phenotype variance.

Methods And Results: Nine hundred eighty-six probe sets mapping on STR1 were selected from the Rat RAE230A array and screened through a microarray differential expression analysis in brains of SHRSP and stroke-resistant SHR (SHRSR) fed with either regular diet or JD.
