BACKGROUND: Available therapies for myelofibrosis can exacerbate cytopenias and are not indicated for patients with severe thrombocytopenia. Pacritinib, which inhibits both JAK2 and FLT3, induced spleen responses with limited myelosuppression in phase 1/2 trials. We aimed to assess the efficacy and safety of pacritinib versus best available therapy in patients with myelofibrosis irrespective of baseline cytopenias. METHODS: This international, multicentre, randomised, phase 3 trial (PERSIST-1) was done at 67 sites in 12 countries...

Human granulocytic anaplasmosis is a rare, tick-borne infectious disease caused by Anaplasma phagocytophilum. Herein, we report a rare case of human granulocytic anaplasmosis associated with cytopenias and clonal expansion of gamma/delta T-cells in the bone marrow. A 77-year old man presented multiple times to the emergency department complaining of muscle weakness. Complete blood count detected cytopenias and peripheral blood smear showed pseudo Pelger-Huet neutrophils. These findings prompted bone marrow evaluation with ancillary studies including flow cytometry, karyotyping and T-cell rearrangement studies...

Background: The possible role of human coronaviruses (HCoV) in lower respiratory tract disease (LRTD) in hematopoietic cell transplant (HCT) recipients and patients with hematologic malignancies (HM) has not been well studied. Methods: We conducted a retrospective review of HCT/HM patients with HCoV detected in bronchoalveolar lavage (BAL). HCoV strains were identified in BAL samples using strain-specific PCR. Mortality rates were compared among HCT recipients with LRTD caused by HCoV, respiratory syncytial virus (RSV), influenza or parainfluenza virus (PIV) by multivariable Cox regression analysis...

Hemophagocytic lymphohistiocytosis (HLH) is characterized by activation of cytotoxic T and natural killer (NK) cells, and macrophages related to a spectrum of hyperinflammatory disorders. The clinical findings mainly include high fever, cytopenia, splenomegaly, phagocytosis, and proliferation of histiocytes in lymphoreticular tissue. To the best of our knowledge, transfusion-associated graft versus host disease (TA-GVHD) in a 13-day old male newborn with HLH is being reported first time in the literature. The aim of this report was to emphasize the importance of blood products irradiation in the prevention of the development of graft versus host disease especially among high-risk subjects such as newborns with HLH...

Myelodysplastic syndromes (MDS) are oligo-clonal diseases of the hematopoietic stem cell compartment resulting in peripheral cytopenias and a tendency of developing acute myeloid leukemia (AML). MDS show an incidence of approximately 4/100.000/year. However, MDS are mainly a disease of the elderly with a sharp increase in incidence in the age decade above 70 years. Due to the demographic change in western countries, it is expected that the MDS will play an increasing role for these health systems. Although anemia is the predominant cytopenia in the majority of patients, about 30-50% of patients suffer from neutropenia of varying severity...

Hemophagocytic syndrome is a life-threatening disease characterized by the uncontrolled activation of macrophages, resulting in hemophagocytosis of blood cells in the bone marrow. A 20-year-old gravida at 23-week and 5-day gestation was admitted to hospital to evaluate fever up to 104°F of unknown origin, moderate cytopenia, and elevated levels of liver enzymes. Bone marrow biopsy confirmed hemophagocytic syndrome, and polymerase chain reaction came back positive for Mycobacterium tuberculosis. Supportive care and tuberculosis treatment resulted in clinical improvement...

Myelodysplastic syndromes (MDS) represent a heterogeneous group of pre-leukemic disorders, characterized by ineffective hematopoiesis and the abnormal blood cell development of one or more lineages. Oxidative stress, as an important factor in the carcinogenesis of onco-hematological diseases, is also one of the known factors involved in the pathogenesis of MDS. An increase of reactive oxygen species (ROS) may lead to the oxidation of DNA, lipids, and proteins, thereby causing cell damage. Protein carbonylation caused by ROS is defined as an irreversible post-translational oxidative modification of amino acid side chains, and could play an important role in signaling processes...

Anaemia is the commonest cytopenia seen in patients with myelodysplastic syndrome (MDS), and the majority of patients will require transfusion support at some point. Blood transfusions are rich in iron, which leads to the accumulation of body iron over time. It is accepted that this ultimately causes end organ damage and may impact on both morbidity and mortality. In addition, recent data has increased our interest in the subject with regard to the potential impact on stem cell transplant outcome and an anti-leukaemic effect of iron chelation therapy...

The clinical data of 183 patients with hepatitic cirrhosis and portal hypertensive splenomegaly complicated by peripheral cytopenia were retrospectively analyzed to investigate the causes of peripheral cytopenia, as well as the proportion of the causes in these patients. All patients underwent splenectomy. Before operation, these patients had one or more types of peripheral cytopenia (cumulative cytopenia: 390 patient-times). After splenectomy, blood counts in 79.2% (309/390) returned to normal, while in 15...

Hematological abnormalities are very common in the course of systemic lupus erythematosus (SLE). Myelofibrosis is a bone marrow disorder in which there is excessive fibrous tissue formation in the bone marrow. Various benign and malignant disorders can cause or be associated with a diffuse increase in the bone marrow reticular tissue. Some diseases such as infections, neoplasms, and autoimmune diseases may also induce bone marrow fibrosis (secondary myelofibrosis). Cytopenia from autoimmune myelofibrosis (AIMF) in SLE is a rare condition...

OBJECTIVES: While copper deficiency has long been known to cause cytopenias, copper deficiency myeloneuropathy is a more recently described entity. Here, we present the case of two clinically distinct presentations of acquired copper deficiency syndromes secondary to excessive use of zinc-containing denture adhesive over five years: myeloneuropathy and severe macrocytic anemia and neutropenia. METHODS: Extensive laboratory testing and histologic evaluation of the liver and bone marrow, were necessary to rule out other disease processes and establish the diagnosis of copper deficiency...

Splenic marginal zone lymphoma (SMZL) is a distinct lymphoma entity characterized by an indolent clinical course and prolonged survival. Treatment is not standardized, since there are no prospective randomized trials in large series of SMZL patients. Splenectomy and rituximab represent the most effective treatment strategies used so far. The addition of chemotherapy to rituximab has not further improved the outcome, although this issue requires further investigation. Rituximab monotherapy has been associated with high response rates (∼90%), with approximately half of these responses being complete, even at the molecular level...

Myelodysplastic syndromes (MDS) are characterized by progressive bone marrow failure manifesting as blood cytopenia and a variable risk of progression into acute myeloid leukemia. MDS is heterogeneous in biology and clinical behavior. MDS is generally divided into lower-risk (LR) or higher-risk (HR) MDS. Goals of care in HR-MDS is changing the natural history of the disease, whereas in LR-MDS it is symptom control and quality of life. Areas covered: We review the epidemiology, tools of risk assessment, and the available therapeutic modalities for LR-MDS...

The clinical presentation of myelodysplastic syndrome (MDS) is not specific. Many patients can be asymptomatic and can be detected only due to an abnormal complete blood cell count (CBC) on routine exam or for other reasons while others can be symptomatic as a consequence of underlying cytopenias. Thrombotic thrombocytopenic purpura (TTP) usually is suspected under the evidence of microangiopathic hemolytic anemia (MAHA) and thrombocytopenia and because it is a life-threatening condition (medical emergency) immediate initiation of plasmapheresis could be life-saving...
