Anemia, Sideroblastic: Anemia characterized by the presence of erythroblasts containing excessive deposits of iron in the marrow.5-Aminolevulinate Synthetase: An enzyme of the transferase class that catalyzes condensation of the succinyl group from succinyl coenzyme A with glycine to form delta-aminolevulinate. It is a pyridoxyal phosphate protein and the reaction occurs in mitochondria as the first step of the heme biosynthetic pathway. The enzyme is a key regulatory enzyme in heme biosynthesis. In liver feedback is inhibited by heme. EC 2.3.1.37.Anemia: A reduction in the number of circulating ERYTHROCYTES or in the quantity of HEMOGLOBIN.Anemia, Refractory: A severe sometimes chronic anemia, usually macrocytic in type, that does not respond to ordinary antianemic therapy.Genetic Diseases, X-Linked: Genetic diseases that are linked to gene mutations on the X CHROMOSOME in humans (X CHROMOSOME, HUMAN) or the X CHROMOSOME in other species. Included here are animal models of human X-linked diseases.Pyridoxine: The 4-methanol form of VITAMIN B 6 which is converted to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. Although pyridoxine and Vitamin B 6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading (EE Snell; Ann NY Acad Sci, vol 585 pg 1, 1990).Mitochondrial Myopathies: A group of muscle diseases associated with abnormal mitochondria function.Anemia, Aplastic: A form of anemia in which the bone marrow fails to produce adequate numbers of peripheral blood elements.Erythroblasts: Immature, nucleated ERYTHROCYTES occupying the stage of ERYTHROPOIESIS that follows formation of ERYTHROID PRECURSOR CELLS and precedes formation of RETICULOCYTES. The normal series is called normoblasts. Cells called MEGALOBLASTS are a pathologic series of erythroblasts.Anemia, Refractory, with Excess of Blasts: Chronic refractory anemia with granulocytopenia, and/or thrombocytopenia. Myeloblasts and progranulocytes constitute 5 to 40 percent of the nucleated marrow cells.X Chromosome: The female sex chromosome, being the differential sex chromosome carried by half the male gametes and all female gametes in human and other male-heterogametic species.Acidosis, Lactic: Acidosis caused by accumulation of lactic acid more rapidly than it can be metabolized. It may occur spontaneously or in association with diseases such as DIABETES MELLITUS; LEUKEMIA; or LIVER FAILURE.Glutaredoxins: A family of thioltransferases that contain two active site CYSTEINE residues, which either form a disulfide (oxidized form) or a dithiol (reduced form). They function as an electron carrier in the GLUTHIONE-dependent synthesis of deoxyribonucleotides by RIBONUCLEOTIDE REDUCTASES and may play a role in the deglutathionylation of protein thiols. The oxidized forms of glutaredoxins are directly reduced by the GLUTATHIONE.Anemia, Hemolytic: A condition of inadequate circulating red blood cells (ANEMIA) or insufficient HEMOGLOBIN due to premature destruction of red blood cells (ERYTHROCYTES).Preleukemia: Conditions in which the abnormalities in the peripheral blood or bone marrow represent the early manifestations of acute leukemia, but in which the changes are not of sufficient magnitude or specificity to permit a diagnosis of acute leukemia by the usual clinical criteria.Iron: A metallic element with atomic symbol Fe, atomic number 26, and atomic weight 55.85. It is an essential constituent of HEMOGLOBINS; CYTOCHROMES; and IRON-BINDING PROTEINS. It plays a role in cellular redox reactions and in the transport of OXYGEN.Hydro-Lyases: Enzymes that catalyze the breakage of a carbon-oxygen bond leading to unsaturated products via the removal of water. EC 4.2.1.Fanconi Anemia: Congenital disorder affecting all bone marrow elements, resulting in ANEMIA; LEUKOPENIA; and THROMBOPENIA, and associated with cardiac, renal, and limb malformations as well as dermal pigmentary changes. Spontaneous CHROMOSOME BREAKAGE is a feature of this disease along with predisposition to LEUKEMIA. There are at least 7 complementation groups in Fanconi anemia: FANCA, FANCB, FANCC, FANCD1, FANCD2, FANCE, FANCF, FANCG, and FANCL. (from Online Mendelian Inheritance in Man, http://www.ncbi.nlm.nih.gov/entrez/dispomim.cgi?id=227650, August 20, 2004)Ataxia: Impairment of the ability to perform smoothly coordinated voluntary movements. This condition may affect the limbs, trunk, eyes, pharynx, larynx, and other structures. Ataxia may result from impaired sensory or motor function. Sensory ataxia may result from posterior column injury or PERIPHERAL NERVE DISEASES. Motor ataxia may be associated with CEREBELLAR DISEASES; CEREBRAL CORTEX diseases; THALAMIC DISEASES; BASAL GANGLIA DISEASES; injury to the RED NUCLEUS; and other conditions.Bone Marrow: The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.Anemia, Hemolytic, Autoimmune: Acquired hemolytic anemia due to the presence of AUTOANTIBODIES which agglutinate or lyse the patient's own RED BLOOD CELLS.Anemia, Hypochromic: 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.

In humans, erythrocytes are produced by the YOLK SAC in the first trimester; by the liver in the second trimester; by the BONE MARROW in the third trimester and after birth. In normal individuals, the erythrocyte count in the peripheral blood remains relatively constant implying a balance between the rate of erythrocyte production and rate of destruction.Anemia, Sickle Cell: A disease characterized by chronic hemolytic anemia, episodic painful crises, and pathologic involvement of many organs. It is the clinical expression of homozygosity for hemoglobin S.Genetic Linkage: The co-inheritance of two or more non-allelic GENES due to their being located more or less closely on the same CHROMOSOME.

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 ...

Several forms of congenital or progressive ataxia have an X-linked pattern of inheritance. The gene for one form of progressive ataxia, X-linked sideroblastic anemia and ataxia (XLSA/A) has been identified (Table 2). XLSA/A is an infantile-onset gait disorder affecting male children beginning with delayed motor milestones and followed by onset of slowly progressive ataxia between 40 and 50 years of age. The disorder may lead to confinement to wheelchair after at least 10 years of disease progression. Examination of adults shows dysarthria, ataxia of upper limbs and gait, ophthalmoparesis, hypometric saccades, saccadic pursuit, nystagmus, occasional perioral fasciculations, normal to increased deep tendon reflexes and normal plantar reflexes, sensory examination and negative Rhomberg sign. The gene responsible for XLSA/A is located on Xq13 and encodes the human ATP-binding cassette (ABC) transporter ABC7. ...

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 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.

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 ...

The latest electronic edition of the journal Nature Genetics reports the discovery of a new gene responsible for congenital sideroblastic anemia.
Six patients had primary sideroblastic erythropoiesis together with a haemoglobin concentration of 12.0 g/dl or higher. In four cases this was associated with macrocytosis. Other abnormalities included failure of erythroid progenitor growth from peripheral blood in three cases and occasional dysplastic appearances in neutrophils and megakaryocytes. Sideroblastic erythropoiesis seems to be an early manifestation of the myelodysplastic syndrome and may present clinically at a pre-anaemic stage.. ...
ABCB7-related syndromic CSA is an autosomal recessive disease. An individual can be heterozygous for the disorder (healthy carrier) when only one of the ABCB7 allele is mutated, or homozygous or compound heterozygous (affected individual) when two ABCB7 alleles are mutated. A couple who carries each one a mutated ABCB7 allele have a 25 percent risk of having a child affected by the disorder at each pregnancy. The risk of having a child who is a healthy carrier of the disorder is 50 percent at each pregnancy, and the risk that a child will not have the disorder and will not be a carrier is 25 percent. Ask for genetic counselling to get a complete explanation. ...

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). ...

I.B.002. Basophilic stippling. Blood films. (A) Red cell with fine basophilic stippling at center top of field in patient with beta-thalassemia minor. (B) Red cell with coarse basophilic stippling in sideroblastic anemia. Basophilic stippling is a very important marker of disordered erythropoiesis seen notably in thalassemia and sideroblastic and megaloblastic anemia as well as other erythroid disorders. It is not present in iron deficiency anemia and helps in distinguishing that hypochromic-microcytic anemia from thalassemia minor in which careful examination of the blood film will usually permit identification of stippled red cells.. ...
The product of this gene specifies an erythroid-specific mitochondrially located enzyme. The encoded protein catalyzes the first step in the heme biosynthetic pathway.

In the present study, we identified an erythroid-specific enhancer region in the first intron of the human ALAS2 gene (a 130 bp region referred to as ChIPmini), a region which contains ALAS2int1GATA, a functional GATA1-binding site. We also identified the GGTA mutation and the delGATA mutation at ALAS2int1GATA, each of which is associated with XLSA or CSA. Moreover, we confirmed that each mutation diminished the binding of GATA1 transcription factor to ALAS2int1 (Figure 5B) and decreased enhancer activity of ChIPmini (Figure 6A). Thus, the GGTA mutation and delGATA mutation are loss-of function mutations of the ALAS2 gene. In fact, the expression of ALAS2 mRNA in bone marrow erythroblasts was lower in proband 3 (Figure 4B) than in normal controls. Thus, each loss-of function mutation may lead to decreased transcription of the ALAS2 gene, thereby causing sideroblastic anemia in male patients. Such a molecular basis is consistent in part with the lack of pyridoxine responsiveness in these patients ...

Congenital ataxias (CA) are rare, non progressive diseases, characterized by psychomotor retardation, hypotonia followed by ataxia. The presence of the molar tooth on MRI allowed to define Joubert syndrome, a peculiar form of CA. Apart from this group, CA are mostly associated with cerebellar atrophy or hypoplasia without molar tooth on MRI. CA are a clinically as well as genetically heterogeneous group of diseases. Early-onset ataxias are progressive but may be difficult to distinguish from CA in the first years of the disease. To date, few genes responsible for CA have been identified: ABC7 (X-linked CA associated with sideroblastic anemia), SLC9A6 (X-linked CA associated with severe mental retardation, autism and epilepsy), GPR56 (CA associated with polymicrogyria), ATCAY (pure CA in Cayman isolate); the involvement of the ATCAY and ABC7 genes has never been assessed in a large cohort of CA patients.. Primary objective:. To assess the frequency of mutations of the ATCAY and ABC7 genes in ...

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). NAF-1 could therefore be required for proper Fe-S biogenesis or mobilization in cancer cells. In support of such a possibility are the unique properties of the NAF-1-containing Fe-S cluster, namely that it is labile and ...

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. ...
The haematological features of 118 cases of primary myelodysplastic syndromes (PMDS) were reviewed to see how these could be related and classified according to the recent FAB proposals. A majority of the cases were elderly who presented with a macrocytic or normocytic anaemia and reticulocytopenia. Cases of acquired idiopathic sideroblastic anaemia (AISA) usually had normal leucocyte and platelet counts, erythroid hyperplasia, marked dyserythropoiesis and more than 20% ringed sideroblasts. Cases of refractory anaemia with excess of blasts (RAEB) had frequent neutropenia and thrombopenia usually with prominent dysgranulopoiesis and dysthrombopoiesis. Refractory anaemia or refractory cytopenia appeared morphologically to be a heterogeneous group. Leukaemic transformation did not occur in any of these 16 cases of AISA whereas six of the 34 cases of RAEB transformed into acute leukaemia. It appears that the cases of PMDS present with well defined haematological features which permit recognition of ...

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.

Serum ferritin is a sensitive indicator of available iron stores (1), but in certain instances it cannot be used in diagnosis, e.g., in anemias of chronic disease, infections, inflammation, liver disease, and malignancies (2)(3)(4)(5)(6)(7). Iron stores may be normal or increased, though accompanied by increased serum ferritin, in anemias of chronic disorders, aplastic anemia, sideroblastic anemia, and chronic hemolytic anemia. Because ferritin is also a positive acute-phase reactant protein that is increased in inflammation (2), serum ferritin concentration is not a reliable index of available iron stores in individuals with chronic diseases. There is no information, however, on whether ferritin can be used as a marker of available iron stores in the anemia of copper deficiency.. Unlike iron-deficiency anemia, in which body iron stores are usually depleted as evidenced by diminished serum ferritin concentrations, anemia of copper deficiency (8)(9)(10) results from increased hepatic iron stores ...

Mutations of spliceosome components are common in myeloid neoplasms. One of the affected genes, PRPF8, encodes the most evolutionarily conserved spliceosomal protein. We identified either recurrent somatic PRPF8 mutations or hemizygous deletions in 15/447 and 24/450 cases, respectively. Fifty percent of PRPF8 mutant and del(17p) cases were found in AML and conveyed poor prognosis. PRPF8 defects correlated with increased myeloblasts and ring sideroblasts in cases without SF3B1 mutations. Knockdown of PRPF8 in K562 and CD34+ primary bone marrow cells increased proliferative capacity. Whole-RNA deep sequencing of primary cells from patients with PRPF8 abnormalities demonstrated consistent missplicing defects. In yeast models, homologous mutations introduced into Prp8 abrogated a block experimentally produced in the second step of the RNA splicing process, suggesting that the mutants have defects in proof-reading functions. In sum, the exploration of clinical and functional consequences suggests that PRPF8

Zinc protoporphyrin (ZPP) is a compound found in red blood cells when heme production is inhibited by lead and/or by lack of iron. Instead of incorporating a ferrous ion, to form heme, protoporphyrin IX, the immediate precursor of heme, incorporates a zinc ion, forming ZPP. The reaction to insert a ferrous ion into protoporphyrin IX is catalyzed by the enzyme ferrochelatase. Measurement of zinc protoporphyrin in red cells has been used as a screening test for lead poisoning. and for iron deficiency. There are a number of specific clinical situations in which this measurement has been found to be useful. Zinc protoporphyrin levels can be elevated as the result of a number of conditions, for instance: lead poisoning iron deficiency sickle cell anemia sideroblastic anemia anemia of chronic disease vanadium exposure erythropoietic protoporphyria Varying types of cancer The virtue of elevated ZPP testing as a screen is that all of these conditions can be considered worth discovering.

A new method has been developed for the assay of serum pyridoxal using L. casei. Bound pyridoxal phosphate in serum is converted by acid hydrolysis to pyridoxal for which this organism is specific. This method proved to be considerably more sensitive than other methods so far reported in the literature.. Serum pyridoxal concentrations were measured in 151 control subjects aged 17 to 80 years. The range of concentrations found was 1·5 to 13·5 ng/ml which compared well with values obtained by most workers measuring pyridoxal phosphate by enzymatic methods. A marked fall with age was confirmed, and levels in women of childbearing age were lower than in men of comparable age. Subnormal serum pyridoxal concentrations were found in 62% of patients with sideroblastic anaemia and in the majority of patients with rheumatoid arthritis, Crohns disease, coeliac disease, and in pregnant women at term.. ...
Perturbation in iron homeostasis is a hallmark of some hematologic diseases. Abnormal sideroblasts with accumulation of iron in the mitochondria are named ring sideroblasts (RS). RS is a cardinal feature of refractory anemia with RS (RARS) and RARS with marked thrombocytosis (RARS/-T). Mutations in SF3B1, a member of the RNA-splicing are frequent in RARS/-T and defects of this gene were linked to RS formation. Here we showcase the differences in iron architecture of SF3B1 mutant and wild type (WT) RARS/-T and provide new mechanistic insights by which
BACKGROUND: Myelodysplastic syndromes are characterised by ineffective erythropoiesis. Luspatercept (ACE-536) is a novel fusion protein that blocks transforming growth factor beta (TGF β) superfamily inhibitors of erythropoiesis, giving rise to a promising new investigative therapy. We aimed to assess the safety and efficacy of luspatercept in patients with anaemia due to lower-risk myelodysplastic syndromes. METHODS: In this phase 2, multicentre, open-label, dose-finding study (PACE-MDS), with long-term extension, eligible patients were aged 18 years or older, had International Prognostic Scoring System-defined low or intermediate 1 risk myelodysplastic syndromes or non-proliferative chronic myelomonocytic leukaemia (white blood cell count ,13 000/μL), and had anaemia with or without red blood cell transfusion support ...

Treatment with erythropoietin (epo) may improve the anemia of myelodysplastic syndromes (MDS) in approximately 20% of patients. Previous studies have suggested that treatment with the combination of granulocyte colony-stimulating factor (G-CSF) and epo may increase this response rate. In the present phase II study, patients with MDS and anemia were randomized to treatment with G-CSF + epo according to one of two alternatives; arm A starting with G-CSF for 4 weeks followed by the combination for 12 weeks, and arm B starting with epo for 8 weeks followed by the combination for 10 weeks. Fifty evaluable patients (10 refractory anemia [RA], 13 refractory anemia with ring sideroblasts [RARS], and 27 refractory anemia with excess blasts [RAEB]) were included ...
OBJECTIVE: The current therapy of myelodysplastic syndrome (MDS) is unsatisfactory and comprises mainly supportive treatment or antileukemic chemotherapy. Recent studies about successful immunosuppressive therapy suggest an autoimmune mechanism in subtypes of myelodysplastic syndrome. PATIENTS AND METHODS: To investigate this hypothesis, bone marrow mononuclear cells (MNC) from 15 patients with low-grade MDS, refractory anemia, and refractory anemia with ringed sideroblasts (RA and RARS), and from 7 normal donors were depleted of CD2(+), CD5(+), and CD7(+) lymphocytes using magnetic cell sorting. Depleted and nondepleted MNC were seeded onto irradiated allogeneic bone marrow stroma and the generation of colony-forming-cells (CFC), the clonal origin of hemopoietic progenitor cells in long-term bone marrow culture (LTC), was compared. RESULTS: The capacity of MNC from 7 healthy donors to generate hemopoiesis remained unchanged in the lymphocyte-depleted LTC. In contrast, cultures initiated with ...

Refractory Anaemia (RA) is part of the heterogeneous group of diseases that affects normal blood cell production in the bone marrow and a category of myelodysplastic syndrome (MDS) . One example of RA is the 5q-syndrome. In RA, marrow blood cells fail to mature properly and are unable to work properly. They often die before they leave the marrow, or shortly after reaching the bloodstream (ineffective erythropoiesis or dyserythropoiesis). There are few data on the epidemiology of RA, which may account for 30-40% of all MDS cases. MDS is predominantly diagnosed in the elderly population. The global incidence of all MDS was comprised between 3,5 and 12,6 new cases / year / per 100,000 in some studies. ...
With increasing recognition of newly identified molecular features, the 2016 revision to the WHO classification includes several changes in the myeloid and lymphoid categories, with improved characterization of diseases. Growing data has become available on recurring mutations and pattern of co-mutations in many hematopoietic neoplasms that has allowed recognition of new entities and refined the diagnostic criteria of existing entities. Among myeloid neoplasms, newly discovered molecular genetic abnormalities have resulted in a new myeloid/lymphoid neoplasm disease entity associated with PCM1-JAK2 rearrangement and have enhanced our understanding of myelodysplastic syndromes with ring sideroblasts. Recognition of myeloid neoplasms occurring in the background of germline predisposing mutations is also emphasized in the revision and a new disease category has been created to encompass this group. Among the lymphomas, there has been clarification of certain lymphoma subtypes that most commonly ...

Para muchos quizás no cumplo con los estándares de belleza porque soy gorda, porque tengo muslos y caderas anchas, tengo celulitis, cicatrices y muchas otras cosas más que la mayoría de nosotros tiene, pero que no nos atrevemos a mostrar. Por mi parte les digo, que en el momento en el que todo eso pasa a segundo plano y uno logra enfocarse en las cosas hermosas y positivas de cada ser, eso hace parte de un conjunto de belleza quizás no convencional pero sí real. No satanicemos más nuestros cuerpos ni idealicemos un concepto de belleza casi inalcanzable ...

The prevalence of iron deficiency anemia is 2 percent in adult men, 9 to 12 percent in non-Hispanic white women, and nearly 20 percent in black and Mexican-American women. Nine percent of patients older than 65 years with iron deficiency anemia have a gastrointestinal cancer when evaluated. The U.S. Preventive Services Task Force currently recommends screening for iron deficiency anemia in pregnant women but not in other groups. Routine iron supplementation is recommended for high-risk infants six to 12 months of age. Iron deficiency anemia is classically described as a microcytic anemia. The differential diagnosis includes thalassemia, sideroblastic anemias, some types of anemia of chronic disease, and lead poisoning. Serum ferritin is the preferred initial diagnostic test. Total iron-binding capacity, transferrin saturation, serum iron, and serum transferrin receptor levels may be helpful if the ferritin level is between 46 and 99 ng per mL (46 and 99 mcg per L); bone marrow biopsy may be necessary in
MGI Pharma, Inc, and SuperGen, Inc, recently announced that the US Food and Drug Administration (FDA) has approved the hypomethylating agent decitabine (Dacogen) for injection. Decitabine is indicated for treatment of patients with myelodysplastic syndromes (MDS) including previously treated and untreated, de novo, and secondary MDS of all French-American-British (FAB) subtypes (refractory anemia, refractory anemia with ringed sideroblasts, refractory anemia with excess blasts, refractory anemia with excess blasts in transformation, and chronic myelomonocytic leukemia), and intermediate-1, intermediate-2, and high-risk International Prognostic Scoring System (IPSS) groups. 1

There are many studies about thearchaeology of the City of Konya. Still, these studies remain separate fromeach other. It is important to create an "ArchaeologyMaster Plan" of the town about past, especially archaeological periods, bypreparing the restitution of the City. The traditional town center and thetraditional residential pattern are within the borders of the MeramMunicipality and Karatay Municipality. The Greater Municipality also has authorityover these two municipalities. For instance, the study on thePreservation-Aimed Planning for the Surroundings of Piri Mehmed Pasa has beenmade by Karatay Municipality, whereas the Historical Town CenterPreservation-Aimed Planning studies were made by the Greater Municipality. Thepreservation plans around the Mevlana have, on the other hand, been prepared bythe Ministry of Culture. The Konya Province is directing the project andapplication works around the Mevlana Kulliyesi and its close proximity. As canbe seen, the chaos of authority and ...

BACKGROUND AND OBJECTIVE: Anemia leading to transfusion is probably the most important problem in patients with myelodysplastic syndromes (MDS). Human recombinant erythropoietin (rHuEpo) and granulocyte colony-stimulating factor (G-CSF) have been used to treat patients with anemia of MDS, but fewer than 50% respond. The aim of this work was to evaluate the benefit of rHuEpo +/- G-CSF treatment and to isolate the response predictive variables in a group of selected patients with MDS. DESIGN AND METHODS: A non-randomized multicenter trial was carried out in 32 patients with MDS. The inclusion criteria were age ,= 18 years, refractory anemia (RA) or refractory anemia with ringed sideroblasts, Hb ,= 100 g/L or receiving transfusions and serum erythropoietin ,= 250 U/L. These patients were treated with subcutaneous rHuEpo (300 U/kg) three times a week for 8 weeks. In the case of partial response (PR) or no response (NR) subcutaneosly administered G-CSF (1 microg/kg) three times a week was added to ...
Microcytic Anemias are a categorization of anemias defined as those anemias which yield smaller-than-normal erythrocytes (i.e. Low Mean Corpuscular Volume or MCV). In general, a relatively limited set of pathophysiological processes yield microcytic anemias and thus measurement of the MCV can significantly narrow the possible differential diagnosis for a patients anemia ...

Complejos: son de absorción más lenta, y actúan más como energía de reserva. que son los carbohidratos? La principal función de los carbohidratos es proveer de energía al cuerpo para realizar todas las actividades vitales. El organismo los transforma en glucosa. Los carbohidratos pueden ser absorbidos directamente en el intestino sin necesidad de ser degradados. Una vez absorbidos pasan al hígado, que es capaz de almacenarlos en forma de un derivado del azúcar, el glucógeno. Este es transformado continuamente en glucosa que pasa a la sangre y que es consumida por todas las células del organismo.

Investigators at University Hospital, Zurich, Switzerland, and multiple centers in Europe and Canada, sequenced the pyridoxal 5-phosphate oxidase (PNPO) gene in 31 patients with pyridoxine-responsive seizures but normal biomarkers for antiquitin deficiency and normal sequencing of the ALDH7A1 gene. Eleven patients from 7 families carried 3 novel mutations of the PNPO gene. Response to pyridoxine was prompt in 4 patients, delayed in 2, on EEG only in 2, and initially absent in another 2 patients. Earlier and continuous pyridoxine therapy was related to a better prognosis. Two unrelated patients homozygous for the pArg225His mutation developed status epilepticus when switched to pyridoxal 5-phosphate (PLP).. The findings shift the paradigm of exclusive PLP responsiveness of patients with PNPO deficiency and contradict the strategy of using PLP instead of pyridoxine as the first-line vitamin to test for all inborn errors with vitamin B6-responsive seizures. Testing for PNPO mutations is important ...
