Anemia characterized by a decrease in the ratio of the weight of hemoglobin to the volume of the erythrocyte, i.e., the mean corpuscular hemoglobin concentration is less than normal. The individual cells contain less hemoglobin than they could have under optimal conditions. Hypochromic anemia may be caused by iron deficiency from a low iron intake, diminished iron absorption, or excessive iron loss. It can also be caused by infections or other diseases, therapeutic drugs, lead poisoning, and other conditions. (Stedman, 25th ed; from Miale, Laboratory Medicine: Hematology, 6th ed, p393)

Four new mutations in the erythroid-specific 5-aminolevulinate synthase (ALAS2) gene causing X-linked sideroblastic anemia: increased pyridoxine responsiveness after removal of iron overload by phlebotomy and coinheritance of hereditary hemochromatosis. (1/161)

X-linked sideroblastic anemia (XLSA) in four unrelated male probands was caused by missense mutations in the erythroid-specific 5-aminolevulinate synthase gene (ALAS2). All were new mutations: T647C, C1283T, G1395A, and C1406T predicting amino acid substitutions Y199H, R411C, R448Q, and R452C. All probands were clinically pyridoxine-responsive. The mutation Y199H was shown to be the first de novo XLSA mutation and occurred in a gamete of the proband's maternal grandfather. There was a significantly higher frequency of coinheritance of the hereditary hemochromatosis (HH) HFE mutant allele C282Y in 18 unrelated XLSA hemizygotes than found in the normal population, indicating a role for coinheritance of HFE alleles in the expression of this disorder. One proband (Y199H) with severe and early iron loading coinherited HH as a C282Y homozygote. The clinical and hematologic histories of two XLSA probands suggest that iron overload suppresses pyridoxine responsiveness. Notably, reversal of the iron overload in the Y199H proband by phlebotomy resulted in higher hemoglobin concentrations during pyridoxine supplementation. The proband with the R452C mutation was symptom-free on occasional phlebotomy and daily pyridoxine. These studies indicate the value of combined phlebotomy and pyridoxine supplementation in the management of XLSA probands in order to prevent a downward spiral of iron toxicity and refractory anemia.  (+info)

Mutation of a putative mitochondrial iron transporter gene (ABC7) in X-linked sideroblastic anemia and ataxia (XLSA/A). (2/161)

X-linked sideroblastic anemia and ataxia (XLSA/A) is a recessive disorder characterized by an infantile to early childhood onset of non-progressive cerebellar ataxia and mild anemia with hypochromia and microcytosis. A gene encoding an ATP-binding cassette (ABC) transporter was mapped to Xq13, a region previously shown by linkage analysis to harbor the XLSA/A gene. This gene, ABC7, is an ortholog of the yeast ATM1 gene whose product localizes to the mitochondrial inner membrane and is involved in iron homeostasis. The full-length ABC7 cDNA was cloned and the entire coding region screened for mutations in a kindred in which five male members manifested XLSA/A. An I400M variant was identified in a predicted transmembrane segment of the ABC7 gene in patients with XLSA/A. The mutation was shown to segregate with the disease in the family and was not detected in at least 600 chromosomes of general population controls. Introduction of the corresponding mutation into the Saccharomyces cerevisiae ATM1 gene resulted in a partial loss of function of the yeast Atm1 protein. In addition, the human wild-type ABC7 protein was able to complement ATM1 deletion in yeast. These data indicate that ABC7 is the causal gene of XLSA/A and that XLSA/A is a mitochondrial disease caused by a mutation in the nuclear genome.  (+info)

Prognostic significance of magnetic resonance imaging of femoral marrow in patients with myelodysplastic syndromes. (3/161)

PURPOSE: To investigate whether the abnormalities observed on femoral marrow magnetic resonance images are related to the development of leukemia and survival of patients with myelodysplastic syndromes (MDS). PATIENTS AND METHODS: The findings on magnetic resonance images of the femoral marrow were evaluated over periods of 1 to 92 months (median, 18 months) in 42 consecutive adult patients with newly diagnosed MDS. Magnetic resonance images were obtained by the T1-weighted spin echo method and the short T1 inversion recovery technique. RESULTS: Magnetic resonance images showed that the femoral marrow patterns changed from fatty, faint, or nodular to scattered or uniform as the disease progressed. Development of acute myeloid leukemia was observed in only 13 patients whose marrow exhibited a scattered or uniform pattern. The overall survival of the 29 patients with a scattered or uniform marrow pattern was significantly shorter than that of the 13 patients with a fatty, faint, or nodular marrow pattern (10.7% v 73.3% at 7 years; P < .01). The period of leukemia-free survival was also significantly shorter in the patients with a scattered or uniform marrow pattern versus a fatty, faint, or nodular pattern (37.7% v 100% at 7 years; P < .01). CONCLUSION: Magnetic resonance images of the femoral marrow can provide valuable information for assessing the prognosis and determining the most appropriate management of patients with MDS.  (+info)

Nonrandom chromosomal abnormalities in hematologic disorders of man. (4/161)

A nonrandom pattern of chromosomal abnormalities occurs in bone marrow cells obtained from patients with hematologic disorders who have an abnormal karyotype involving a C group chromosome. An additional number 8 chromosome is the most common abnormality, found in more than one-half of the patients studies. An additional number 9 chromosome and the loss of all or part of a number 7 are abnormalities that occur more often than might be expected by chance. It is proposed that specific human chromosomal abnormalities may be related to different specific etiologic agents.  (+info)

Mother cell of megakaryocyte. (5/161)

It was attempted to describe the morphology of the most immature cell of megakaryocytic series. The megakaryocytes were observed with the electron microscope in five cases, being traced back to their immature forms. In two cases the most immature cells of megakaryocytic series were considered to be the cells which were probably identified as lymphocytes under the light microscope, but they were not lymphocytes with the electron microscope. In other two cases it was presumed that neutrophilic and megakaryocytic series were derived from morphologically similar immature cells, since the most immature cells of neutrophilic and megakaryocytic series were not distinguished when they were traced back to their immature forms. These findings suggest that mother cells of megakaryocytes in the adult bone marrow may be identified as lymphoid cells with the light microscope.  (+info)

Mechanism of platelet liberation. (6/161)

Megakaryocytes from 5 patients and 1 normal person were observed electronmicroscopically. In some pathologic states platelets seemed to be liberated without demarcation membrane system (DMS) and in a normal individual they seemed to be liberated independently of DMS. These findings suggest that DMS is not concerned with platelet liberation and that platelets are liberated through pseudopodia and bleb formation. In mature megakaryocytes vigorous amoeboid movement seems to exist and both pseudopodia and blebs may represent this movement. Structural similarity between surface connected system (SCS) of platelet and DMS of megakaryocyte suggests that the structure called DMS is transported as SCS into platelet.  (+info)

Trisomy 8 in the bone marrow associated with high red cell glutathione reductase activity. (7/161)

In a series of 841 patients with hematologic disorders, 10 individuals were found to have an extra C group chromosome in their bone marrow cells. In two the extra chromosome was not identified, but in the remaining eight it was No. 8. Four of these ten patients had leukemia, and the others had cytopenias or other probably preleukemic conditions. The mean value for glutathione reductase activity in the red cells of four patients with trisomy 8 was significantly higher (2980 +/- 940 mumoles/min/liter of erythrocytes) than in normal controls (1930 +/- 360) or in any of five different control groups of patients with hematologic disorders. The extent of enzyme activation as a result of preincubation with exogenous flavin adenine dinucleotide was similar in the erythrocytes of all groups. The reasons for the high values of red cell glutathione reductase activity in patients with trisomy 8 are discussed in the light of the proposed assignment of the gene for that enzyme to chromosome 8.  (+info)

Successful allogeneic bone marrow transplantation for childhood-onset refractory anemia with ringed sideroblasts. (8/161)

Refractory anemia with ringed sideroblasts (RARS) is an extremely rare type of myelodysplastic syndrome in children. We describe a 10-year-old boy with RARS presented with pancytopenia. He remained relatively stable with only a few transfusions until age of 20 years, when he underwent an allogeneic bone marrow transplantation (BMT) because of increased transfusion requirements. He remains in complete chimeric state at 20 months posttransplant with normal hematologic parameters. To our knowledge, this is the first description of successful BMT in a patient with childhood-onset RARS. The indication of BMT for this rare disorder in children is discussed.  (+info)

YARS2 variants have previously been described in patients with myopathy, lactic acidosis and sideroblastic anemia 2 (MLASA2). YARS2 encodes the mitochondrial tyrosyl-tRNA synthetase, which is responsible for conjugating tyrosine to its cognate mt-tRNA for mitochondrial protein synthesis. Here we describe 14 individuals from 11 families presenting with sideroblastic anemia and YARS2 variants that we identified using a sideroblastic anemia gene panel or exome sequencing. The phenotype of these patients ranged from MLASA to isolated congenital sideroblastic anemia. As in previous cases, inter- and intra-familial phenotypic variability was observed, however, this report includes the first cases with isolated sideroblastic anemia and patients with biallelic YARS2 variants that have no clinically ascertainable phenotype. We identified ten novel YARS2 variants and three previously reported variants. In vitro amino-acylation assays of five novel missense variants showed that three had less effect on the ...

The essential features of X-linked sideroblastic anemia include the following: (1) a hypochromic microcytic anemia and 2 discrete populations of red blood cells, one microcytic and the other normocytic; (2) marrow ringed sideroblasts, particularly prominent in the late erythroid precursors; (3) a variable hematologic response to pharmacologic doses of pyridoxine; and (4) systemic iron overload secondary to chronic ineffective erythropoiesis. The age of clinical onset of the disorder can vary from in utero to the ninth decade. Whereas males are preferentially affected, females may present with clinically severe anemia. More commonly, female carriers of the disease have an increased red blood cell distribution width and sometimes erythrocyte dimorphism ({18:Fleming, 2002 ...
A 3-month-old boy presented with decreased appetite, fatigue, and a nosebleed. Initial workup revealed hemoglobin 2.6 g/dL (10.2-12.7), hematocrit 7.7% (30.9-37.9), mean corpuscular volume 104 fL (71.3-82.6), white blood cell count 4200/μL (240 absolute neutrophil count), platelets 50 000/μL (140-400), and reticulocyte count 1.31% (1.55-2.7). Bone marrow revealed hypercellularity with cytoplasmic vacuolization of myeloid and erythroid precursors (panels A-B; original magnification ×1000, Wright-Giemsa stain). Iron staining of marrow biopsy revealed numerous ringed sideroblasts (panels C-D; original magnification ×1000, Prussian blue stain). DNA was examined by array-based comparative genomic hybridization and revealed a 4.9-kb deletion, m.11027_15950del4923, consistent with mitochondrial DNA deletion syndrome, also known as Pearson syndrome. Fecal elastase was initially normal, but now it is ,15 μg/g (normal ,200), consistent with severe pancreatic insufficiency. We have begun pancreatic ...
A decade ago, Brooks McMurrays routine check-up was anything but routine. The suburban Boston boys spleen was enlarged. His red blood cell count was low and the cells were very small and very pale, which suggested a serious iron deficiency anemia. The family pediatrician referred McMurray, now a 19-year-old college freshman, to Dana-Farber/Boston Childrens Cancer and Blood Disorders Center.. There hematologists discovered the boy had unexpectedly high iron levels. Together with pathologist Mark Fleming, MD, DPhil, they solved the mystery. McMurray has congenital sideroblastic anemia, an inherited blood disorder so rare that fewer than 1,000 cases have been reported worldwide. Iron was getting stuck in the wrong place in the precursor red blood cells developing in his bone marrow. …. ...

The activity of 5-aminolaevulinate (ALA) synthase, the first and rate-limiting of haem synthesis, was markedly reduced (13% of controls) in erythroblasts of a patient with acquired, primary sideroblastic anaemia (PASA). The reduced activity of ALA synthase could not be restored in vitro with 1 mmol/l pyridoxal-5-phosphate (PLP). Treatment of the patient with pyridoxine for several months increased the ALA synthase activity from 13% to 50% of controls in the absence and to 100% in the presence of PLP in the incubation medium. These studies suggest that both increased degradation of apo-ALA synthase and decreased affinity of ALA synthase for PLP may be involved in pyridoxine-responsive PASA ...
X-linked sideroblastic anemia or X-linked dominant erythropoietic protoporphyria, associated with ALAS2 (aminolevulinic acid synthase), has also been described. X-linked dominant erythropoietic protoporphyria (XDEPP) is caused by a gain of function mutation in the ALAS2 (5-aminolevulinate synthase) gene; that gene encodes the very first enzyme in the heme biosynthetic pathway. The mutation is caused by a frameshift mutation caused by one of two deletions in the ALAS2 exon 11, either c. 1706-1709 delAGTG or c. 1699-1700 delAT. This alters the 19th and 20th residues of the C-terminal domain thereby altering the secondary structure of the enzyme. The delAT mutation only occurred in one family studied whereas the delAGTG mutation occurred in several genetically distinct families. The delAGTG causes a loss of an α-helix which is replaced by a β-sheet. Previously known mutations in the ALAS2 resulted in a loss-of-function mutation causing X-linked sideroblastic anemia. Erythropoietic ...

The pathophysiology of myelodysplasia is complex. There is evidence for impairments in stem cell growth, progenitor maturation, and both growth factor production and progenitor responsiveness. The presence of ineffective hematopoiesis (increased apoptosis of maturing marrow precursors) is a hallmark of myelodysplasia. It appears to correlate in part with CD95 expression and persistent high levels of Fas receptor, resulting in increased fas-ligand apoptosis. Upregulation of the cytokines tumor necrosis factor α (TNF-α) and interleukin 1β (IL-1β) also may play a role in promoting apoptosis of long-term hematopoietic stem cells (LT-HSC) and committed precursors in myelodysplastic marrows. Vascular endothelial growth factor (VEGF) overproduction is thought to be involved in the promotion of myeloblastic elements, and perhaps the evolution to acute myeloid leukemia (AML). ...

Anemia idiopathic affects the body from the formation of blood cells in the process of coagulation. These related anemia diseases called idiopathic received this name due to its unknown origin, types of anemia idiopathic damage or destroy the stem cells which are then converted into red blood cells, as the case of aplastic anemia is idiopathic or idiopathic Myelofibrosis. Sideroblastic anemia makes the body unable to transform iron into hemoglobin, and idiopathic thrombocytopenia is the lack of an adequate number of platelets. Idiopathic diseases are not only limited to the blood, also can affect other regions of the body. Idiopathic, or hypoplasia aplastic anemia, is anemia that usually occurs when the bone marrow stem cells are injured or damaged. Less often, this type of idiopathic anemia occurs as result of damage to the vasculature of the bone marrow itself, therefore, inhibits the growth and the maturity of the red and white blood cells, along with platelets.

Previous studies have suggested that NAF-1 could be involved in maintaining Fe ion homeostasis in cells (Sohn et al., 2013; Tamir et al., 2015). Nevertheless, the precise role of NAF-1 in this process has remained unclear. Here, we show that NAF-1 deficiency results in an increased expression of TfR at the plasma membrane, an increased uptake of transferrin-bound Fe into cells and an increased production of ROS in the mitochondria (Figs 3, 4; Figs S1, S2). Taken together, the alterations in Fe ions and ROS in cancer cells with suppressed NAF-1 expression appear to resemble the alterations in Fe ions and ROS that are induced by the disruption of Fe-S biogenesis in conditions such as Friedreichs ataxia and in some forms of sideroblastic anemia (Napier et al., 2005; Wilson, 2006).

At least 50 mutations that cause X-linked sideroblastic anemia have been identified in the ALAS2 gene. Almost all of these mutations change single protein building blocks (amino acids) in erythroid ALA-synthase. These changes impair the activity of the enzyme, which disrupts the normal production of heme in developing red blood cells. A reduction in the amount of heme prevents these cells from making enough hemoglobin. Because almost all of the iron transported into erythroblasts is normally incorporated into heme, the reduced production of heme leads to a buildup of excess iron in these cells. Additionally, the body attempts to compensate for the hemoglobin shortage by absorbing more iron from the diet. This buildup of excess iron can damage the bodys organs. Low hemoglobin levels and the resulting accumulation of iron in the bodys organs lead to the characteristic features of X-linked sideroblastic anemia. ...

Refractory anaemia with ring sideroblasts (RARS) and marked thrombocytosis (RARS-T) is a provisional entity in the World Health Organisation 2008 classification and has previously been shown to have a high proportion of JAK2(V617F) (Janus Kinase 2) and SF3B1 (Splicing Factor 3B subunit 1) mutations. …
Pearson syndrome is a mitochondrial disease characterized by sideroblastic anemia and exocrine pancreas dysfunction. Other clinical features are failure to thrive, pancreatic fibrosis with insulin-dependent diabetes and exocrine pancreatic deficiency, muscle and neurologic impairment, and, frequently, early death. It is usually fatal in infancy. The few patients who survive into adulthood often develop symptoms of Kearns-Sayre syndrome. It is caused by a deletion in mitochondrial DNA. Pearson syndrome is very rare, less than hundred cases have been reported in medical literature worldwide. The syndrome was first described by pediatric hematologist and oncologist Howard Pearson in 1979; the deletions causing it were discovered a decade later. Pearson Syndrome is a very rare mitochondrial disorder that is characterized by health conditions such as sideroblastic anemia, liver disease, and exocrine pancreas deficiency. Pearson Syndrome is a mitochondrial disease caused by a deletion in mitochondrial ...
Life-threatening iron overload may occur without severe anaemia in patients with sideroblastic disorders. Assessment of erythroid expansion in bone-marrow aspirates may be as useful as ferrokinetic studies in predicting both the risk of iron loading and the need for prophylactic phlebotomy or iron-chelation therapy.

BACKGROUND: Myelodysplastic syndromes are a diverse and common group of chronic hematologic cancers. The identification of new genetic lesions could facilitate new diagnostic and therapeutic strategies. METHODS: We used massively parallel sequencing technology to identify somatically acquired point mutations across all protein-coding exons in the genome in 9 patients with low-grade myelodysplasia. Targeted resequencing of the gene encoding RNA splicing factor 3B, subunit 1 (SF3B1), was also performed in a cohort of 2087 patients with myeloid or other cancers. RESULTS: We identified 64 point mutations in the 9 patients. Recurrent somatically acquired mutations were identified in SF3B1. Follow-up revealed SF3B1 mutations in 72 of 354 patients (20%) with myelodysplastic syndromes, with particularly high frequency among patients whose disease was characterized by ring sideroblasts (53 of 82 [65%]). The gene was also mutated in 1 to 5% of patients with a variety of other tumor types. The observed mutations
The third step in working up an anemia is to assess red cell size (i.e., volume - the mean corpuscular volume [MCV], normal range ca. 80-100 femtoliters) and size distribution (the red blood cell distribution width [RDW], a measure of circulating red cell size variability, attempts to quantitate the older descriptor for size heterogeneity:anisocytosis). An abnormal MCV can be very helpful in narrowing the likely source of anemia. Conversely, a normal MCV cannot be taken to rule out those sources typically associated with microcytosis (MCV, 80) or macrocytosis (MCV,100).. Microcytic anemias (MCV , 80) are invariably due to defects in hemoglobin production. This occurs because of iron deficiency (by far the most common), thalassemia, sideroblastic anemias, or, uncommonly, the anemia of chronic inflammation. Thalassemia trait usually presents with profound microcytosis and mild to moderate anemia (MCV, 70, Hct, 30), in iron deficiency the MCV rarely falls below 80 until the anemia is significant ...

TRNT1 (CCA-adding transfer RNA nucleotidyl transferase) enzyme deficiency is a new metabolic disease caused by defective post-transcriptional modification of mitochondrial and cytosolic transfer RNAs (tRNAs). We investigated four patients from two families with infantile-onset cyclical, aseptic febrile episodes with vomiting and diarrhoea, global electrolyte imbalance during these episodes, sideroblastic anaemia, B lymphocyte immunodeficiency, retinitis pigmentosa, hepatosplenomegaly, exocrine pancreatic insufficiency and renal tubulopathy. Other clinical features found in children include sensorineural deafness, cerebellar atrophy, brittle hair, partial villous atrophy and nephrocalcinosis. Whole exome sequencing and bioinformatic filtering were utilised to identify recessive compound heterozygous TRNT1 mutations (missense mutation c.668T|C, p.Ile223Thr and a novel splice mutation c.342+5G|T) segregating with disease in the first family. The second family was found to have a homozygous TRNT1 mutation

INFO: W Kenii doszło do brutalnej masakry islamistów na pasażerach autobusu, którzy nie chcieli wyprzeć się wiary w Jezusa Chrystusa.. Autobus napakowany pasażerami został zatrzymany przez islamistów z al-Szabab. Terroryści wywlekli podróżnych z pojazdu i zażądali od nich złożenia islamskiego wyznania wiary. 11 osób odmówiło wyparcia się Jezusa i przyjęcia Mahometa, w efekcie czego zostali zamordowani przez swoich islamistycznych oprawców. Władze Kenii potwierdził śmierć co najmniej 6 z nich oraz potępiły brutalną kaźń..
