BACKGROUND: Immunophenotyping of bone marrow (BM) hemopoietic precursors is useful for diagnosis of adult myelodysplastic syndrome (MDS), but data concerning pediatric patients are limited. We analyzed immunophenotypic features of BM cells at diagnosis of children who were referred to the Brazilian Pediatric Cooperative Group of Myelodysplastic Syndromes. METHODS: Diagnosis was based on clinical information, peripheral blood counts, BM cytology and cytogenetics...

INTRODUCTION: Megaloblastic anemia (MA) represents a subtype of macrocytic anemia caused by impaired DNA synthesis, mostly due to folate and vitamin B12 deficiency. Its mildest forms lead to macrocytosis without concomitant anemia, but more severe forms to thrombocytopenia and/or leucopenia as well. In majority of the cases, the diagnosis of MA dose not represent a serious clinical problem, however, other causes of macrocytosis including myelodysplastic syndrome (MDS) must be excluded...

Anemia often develops in rheumatoid arthritis (RA) patients. In the present study, we examined the association between the therapeutic effectiveness of the biologic agent tocilizumab (TCZ) and potential predictors of therapeutic effectiveness. We focused on the amelioration of anemia of chronic inflammation through the mechanism of direct inhibition of Interleukin (IL)-6 receptor-mediated signals by TCZ. Serum hepcidin-25, which is expressed in an IL-6 dependent manner and is a major cause of anemia of chronic inflammation, was measured in 10 RA patients, before and after administration of TCZ...

In comparison with the 2008 World Health Organization "Blue Book" on hematopoietic neoplasms, a small number of changes have been made in the classification. In the lower-risk patients, Refractory Cytopenias with Multilineage Dysplasia and Ring Sideroblasts (RCMD-RS) has been separated from RCMD to recognize the importance of the SF3B1 mutation. Often there has been confusion as to the degree of morphologic dysplasia and/or cytopenias to define some of the lower-risk subtypes. In addition, the type of dysplasia or cytopenias is not always concordant...

According to the recently published 2016 World Health Organization (WHO) classification of myeloid malignancies, myelodysplastic/myeloproliferative neoplasms (MDS/MPN) include atypical chronic myeloid leukemia (aCML), MDS/MPN-unclassifiable (MDS/MPN-U), chronic myelomonocytic leukemia (CMML), juvenile myelomonocytic leukemia (JMML), and MDS/MPN ring sideroblasts with thrombocytosis (MDS/MPN-RS-T). MDS/MPN-RS-T was previously a provisional category known as refractory anemia with ring sideroblasts with thrombocytosis (RARS-T) which has now attained a distinct designation in the 2016 WHO classification...

Variants in ETV6, which encodes a transcription repressor of the E26 transformation-specific family, have recently been reported to be responsible for inherited thrombocytopenia and hematologic malignancy. We sequenced the DNA from cases with unexplained dominant thrombocytopenia and identified six likely pathogenic variants in ETV6, of which five are novel. We observed low repressive activity of all tested ETV6 variants and variants located in the E26 transformation-specific binding domain (encoding p.A377T, p...

More than 80% of patients with the refractory anemia with ring sideroblasts subtype of myelodysplastic syndrome (MDS) have mutations in Splicing Factor 3B, Subunit 1 (SF3B1). We generated a conditional knockin mouse model of the most common SF3B1 mutation, Sf3b1(K700E). Sf3b1(K700E) mice develop macrocytic anemia due to a terminal erythroid maturation defect, erythroid dysplasia, and long-term hematopoietic stem cell (LT-HSC) expansion. Sf3b1(K700E) myeloid progenitors and SF3B1-mutant MDS patient samples demonstrate aberrant 3' splice-site selection associated with increased nonsense-mediated decay...

Introduction The achievement of erythropoiesis in hemodialysis (HD) patients is typically managed with erythropoiesis-stimulating-agents (ESA's) and intravenous iron (IV-iron). Using this treatment strategy, HD patients frequently show an elevated fraction of red blood cells (RBC) with hemoglobin (Hb) content per cell that is below the normal range, called hypochromic RBC. The low Hb content per RBC is the result of the clinical challenge of providing sufficient iron content to the bone marrow during erythropoiesis...

Erythroleukemia was considered an acute myeloid leukemia in the 2008 World Health Organization (WHO) classification and is defined by the presence of ≥50% bone marrow erythroblasts, having <20% bone marrow blasts from total nucleated cells but ≥20% bone marrow myeloblasts from nonerythroid cells. Erythroleukemia shares clinicopathologic features with myelodysplastic syndromes, especially with erythroid-predominant myelodysplastic syndromes (≥50% bone marrow erythroblasts). The upcoming WHO revision proposes to eliminate the nonerythroid blast cell count rule and to move erythroleukemia patients into the appropriate myelodysplastic syndrome category on the basis of the absolute blast cell count...

BACKGROUND: Allogeneic hematopoietic stem cell transplantation (HSCT) is potentially curative in a variety of hematological malignancies. Graft-vs.-host disease (GvHD) remains a life-threatening complication. Standard treatment is high-dose (HD) corticosteroids. Steroid-refractory (SR) GvHD is associated with poor prognosis. At present, second-line treatment is ill-defined and includes a number of agents. Novel insights into the pathophysiology of acute GvHD (aGvHD) highlight the relevant role of the host inflammatory response governed by several kinase families, including Janus kinases (JAK)1/2...

Anemia of chronic disease (ACD) is a leading cause of anemic syndrome in patients with rheumatoid arthritis (RA). Enhanced hepcidin production mainly stimulated by excess interleukin-6 levels is a key pathodgentic component of ACD (frequently known as anemia of inflammation) by causing the degradation of the transmembrane protein ferroportin, hepcidin impairs iron metabolism. On the basis of the material of recent publications the review gives present-day views on the pathodgenesis of ACD in RA, approaches to the diagnosis and differential diagnosis of ACD, especially in its concomitance with iron-deficiency anemia, as well as approaches to therapy for the type of anemic syndrome with the complex mechanism for its development...

In acute erythroleukemia, erythroid/myeloid subtype, blasts usually comprise 5-19% of total bone marrow cells, similar to the myelodysplastic syndrome subtype refractory anemia with excess blasts; recent studies have raised the question if acute erythroleukemia should be considered as a myelodysplastic syndrome subtype. We reviewed 77 de novo acute erythroleukemia and 279 de novo refractory anemia with excess blasts from three large medical centers. Compared to refractory anemia with excess blasts, acute erythroleukemia patients had higher total bone marrow blasts, lower platelets, hemoglobin, and absolute neutrophil counts, with more patients being assigned a very-poor-karyotype risk and very-high Revised International Prognostic Scoring System score...

PURPOSE: WHO classification of myeloid malignancies is based mainly on the percentage of bone marrow (BM) blasts. This is considered from total nucleated cells (TNCs), unless there is erythroid-hyperplasia (erythroblasts ≥ 50%), calculated from nonerythroid cells (NECs). In these instances, when BM blasts are ≥ 20%, the disorder is classified as erythroleukemia, and when BM blasts are < 20%, as myelodysplastic syndrome (MDS). In the latter, the percentage of blasts is considered from TNCs...

Chromosomal abnormalities lead to the development of hematologic malignancies such as Myelodysplastic Syndrome (MDS). Known chromosomal changes causing MDS include deletion of the long arm of chromosome 5, runt-related transcription factor 1 (RUNX1) also known as acute myeloid leukemia 1 protein (AML1), and very rarely fusion genes involving RUNX1 at t(5;21)(q15;q22). We present a case of a 71-year-old female with MDS, refractory anemia with excess blasts, type 1, with a combination of two cytogenetic abnormalities, specifically a concomitant translocation between chromosomes 5q15 and 21q22 and deletion of chromosome 5q13q33...
