A complex haemoglobinopathy diagnosis in a family with both beta zero- and alpha (zero/+)-thalassaemia homozygosity. (1/248)

The occurrence of point mutation alpha-thalassaemia and of complex combinations of haemoglobin defects is underestimated. Haemoglobinopathies, the most frequent monogenic recessive autosomal disorder in man, occur predominantly in Mediterranean, African and Asiatic populations. However, countries of immigration with a low incidence in the indigenous population, are now confronted with a highly heterogeneous array of imported defects. Furthermore, the occurrence of severe phenotypes is bound to increase in the near future because of the endogamous growth of the ethnical minorities and the lack of prevention. We describe an Afghan family in which both partners of a consanguineous relationship are carriers of a beta- as well as an alpha-thalassaemia determinant. The combination of defects was revealed by the in vitro measurement of the beta/alpha biosynthetic ratio and was characterised at the DNA level. The molecular defects involved are the Cd5(-CT), a Mediterranean beta zero-thalassaemia mutation, and the alpha 2(zero/+)-thalassaemia AATA(-AA) polyadenylation defect. The alpha-thalassemia defect is a rare RNA-processing mutant described only twice before in heterozygous form in Asian-Indian patients. The mutation suppresses the expression of a alpha 2 gene and reduces the expression of the less efficient, 3' located alpha 1 gene as well, inducing a near alpha zero-thalassaemia phenotype. This defect is now described for the first time in the homozygous condition in one of the children who, in addition to being homozygous for the alpha-thalassaemia point mutation, is also a carrier of the beta zero-thalassaemia defect. A previously described homozygous case of the alpha (zero/+)-thalassaemia condition, caused by a similar polyadenylation defect, was characterised by a severe HbH disease. However, the patient described here present at 7 years of age with severe caries, like his beta-thalassaemia homozygous brother but without hepatosplenomegaly, haemolysis or severe anaemia. The haematological analysis revealed 9.5 g/dl Hb; 5.4 x 10(12)/I RBC; 0.33 I/I PCV; 61 fl MCV; 17.6 pg MCH and 6.2% of HbA2. The biosynthetic ratio beta:alpha was 1.6 and no HbH fraction was detectable either on electrophoresis or as inclusion bodies. The parents reported no complications during pregnancy, at birth, or in the neonatal period in rural Afghanistan. We presume therefore that the counterbalancing effect induced by the co-existing beta-thalassaemia defect could have modified a potentially severe perinatal HbH disease into a strongly hypochromic but well compensated 'alpha zero-like heterozygous' thalassaemia phenotype. The risk of a severe HbH disease, could have been easily missed in this family which was referred because of a child affected with beta-thalassaemia major.  (+info)

Cardiac blood flow studies in fetuses with homozygous alpha-thalassemia-1 at 12-13 weeks of gestation. (2/248)

OBJECTIVE: Fetuses affected by homozygous alpha-thalassemia-1 develop anemia as early as the first trimester. Our objective was to study hemodynamic indices in affected fetuses at 12-13 weeks of gestation to determine whether these would be useful in the prediction of anemia. DESIGN: Prospective observational study. SUBJECTS: Women referred before 14 weeks of gestation for the prenatal diagnosis of homozygous alpha-thalassemia-1. METHODS: Transabdominal and/or transvaginal Doppler sonography was performed to measure the flow velocities in the fetal ascending aorta and pulmonary artery at 12-13 weeks. The Doppler indices were compared between those that were subsequently confirmed to be affected by homozygous alpha-thalassemia-1 and those that were unaffected. RESULTS: Between June 1997 and April 1998, 60 eligible women were recruited. Doppler examination was successful in 58 fetuses. Of these, 22 were subsequently confirmed to be affected by homozygous alpha-thalassemia-1. The diagnosis was made by chorionic villus sampling and DNA analysis in two affected fetuses and by cordocentesis and hemoglobin evaluation in 20 affected fetuses. Hemoglobin concentrations could be measured in ten fetuses and these ranged from 4 to 8 g/dl. The affected fetuses had significantly higher peak velocities at the pulmonary valve and ascending aorta and a larger inner diameter of the pulmonary valve than that in unaffected fetuses. The total cardiac output was increased by one-third in affected fetuses and was mainly due to an increase of the right-side cardiac output. CONCLUSION: In the early stage of anemia, the fetus responds mainly by increasing its right-side cardiac output. However, there is extensive overlap of the values of cardiac output between the affected and the unaffected fetuses, precluding its use in the prediction of anemia.  (+info)

Evaluation of a mutation screening strategy for sporadic cases of ATR-X syndrome. (3/248)

We report on the evaluation of a strategy for screening for XNP/ATR-X mutations in males with mental retardation and associated dysmorphology. Because nearly half of the mutations in this gene reported to date fall into a short 300 bp region of the transcript, we decided to focus in this region and to extend the mutation analysis to cases with a negative family history. This study includes 21 mentally retarded male patients selected because they had severe mental retardation and a typical facial appearance. The presence of haemoglobin H or urogenital abnormalities was not considered critical for inclusion in this study. We have identified six mutations which represents a mutation detection rate of 28%. This figure is high enough for us to propose this strategy as a valid first level of screening in a selected subset of males with mental retardation. This approach is simple, does not require RNA preparation, does not involve time consuming mutation detection methods, and can thus be applied to a large number of patients at a low cost in any given laboratory.  (+info)

Intrathoracic extramedullary haematopoiesis complicated by massive haemothorax in alpha-thalassaemia. (4/248)

Intrathoracic extramedullary haematopoiesis (EMH) is a rare entity that is usually asymptomatic. A 44 year old man with alpha-thalassaemia is described who developed dyspnoea and massive left sided haemothorax. The haemoglobin disorder was established by Hgb H staining and haemoglobin electrophoretic studies. The DNA analysis revealed it to be a case of double heterozygous terminal codon mutation with the genotype alphaalphaCS/alphaalphaT. Computed tomographic scanning and magnetic resonance imaging of the thorax showed multiple paravertebral masses which were found by thoracoscopic biopsy to be extramedullary haematopoiesis. Although no additional sclerosing pleurodesis or low dose radiation therapy was given, the lung expanded well and there has been no recurrence of haemothorax to date.  (+info)

Impairment of Plasmodium falciparum growth in thalassemic red blood cells: further evidence by using biotin labeling and flow cytometry. (5/248)

Certain red blood cell (RBC) disorders, including thalassemia, have been associated with an innate protection against malaria infection. However, many in vitro correlative studies have been inconclusive. To better understand the relationship between human RBCs with thalassemia hemoglobinopathies and susceptibility to in vitro infection, we used an in vitro coculture system that involved biotin labeling and flow cytometry to study the ability of normal and variant RBC populations in supporting the growth of Plasmodium falciparum malaria parasites. Results showed that both normal and thalassemic RBCs were susceptible to P falciparum invasion, but the parasite multiplication rates were significantly reduced in the thalassemic RBC populations. The growth inhibition was especially marked in RBCs from alpha-thalassemia patients (both alpha-thalassemia1/alpha-thalassemia2 and alpha-thalassemia1 heterozygote). Our observations support the contention that thalassemia confers protection against malaria and may explain why it is more prevalent in malaria endemic areas.  (+info)

The contribution of alpha+-thalassaemia to anaemia in a Nigerian population exposed to intense malaria transmission. (6/248)

The proportion to which alpha-thalassaemia contributes to anaemia in Africa is not well recognized. In an area of intense malaria transmission in South-West Nigeria, haematological parameters of alpha-thalassaemia were examined in 494 children and 119 adults. The -alpha3.7 type of alpha+-thalassaemia was observed at a gene frequency of 0.27. Nine and 36.5% of individuals were homozygous and heterozygous, respectively. P.falciparum-infection was present in 78% of children and in 39% of adults. The alpha-globin genotypes did not correlate with the prevalence of P. falciparum-infection. alpha+-thalassaemic individuals had significantly lower mean values of haemoglobin, mean corpuscular volume, and mean corpuscular haemoglobin than non-thalassaemic subjects. Anaemia was seen in 54. 7% of children with a normal alpha-globin genotype, in 69.9% of heterozygous (odds ratio: 1.99, 95% confidence interval: 1.32-3.00, P = 0.001), and in 88.4% of homozygous alpha+-thalassaemic children (odds ratio: 7.72, 95% confidence interval: 2.85-20.90, P = 0.0001). The findings show that alpha+-thalassaemia contributes essentially to mild anaemia, microcytosis, and hypochromia in Nigeria.  (+info)

A normal beta-globin allele as a modifier gene ameliorating the severity of alpha-thalassemia in mice. (7/248)

Thalassemia is a heritable human anemia caused by a variety of mutations that affect expression of the alpha- or the beta-chain of hemoglobin. The expressivity of the phenotype is likely to be influenced by unlinked modifying genes. Indeed, by using a mouse model of alpha-thalassemia, we find that its phenotype is strongly influenced by the genetic background in which the alpha-thalassemia mutation resides [129(sv/ev)/129(sv/ev) (severe) or 129(sv/ev)/C57BL/6 (mild)]. Linkage mapping indicates that the modifying gene is very tightly linked to the beta-globin locus (Lod score = 13.3). Furthermore, the severity of the phenotype correlates with the size of beta-chain-containing inclusion bodies that accumulate in red blood cells and likely accelerate their destruction. The beta-major globin chains encoded by the two strains differ by three amino acids, one of which is a glycine-to-cysteine substitution at position 13. The Cys-13 should be available for interchain disulfide bridging and consequent aggregation between excess beta-chains. This normal polymorphic variation between murine beta-globin chains could account for the modifying action of the unlinked beta-globin locus. Here, the variation in severity of the phenotype would not depend on a change in the ratio between alpha- and beta-chains but on the chemical nature of the normal beta-chain, which is in excess. This work also indicates that modifying genes can be normal variants that-absent an apparent physiologic rationale-may be difficult to identify on the basis of structure alone.  (+info)

Nuchal translucency in fetuses affected by homozygous alpha-thalassemia-1 at 12-13 weeks of gestation. (8/248)

OBJECTIVE: Fetuses affected by homozygous alpha-thalassemia-1 are anemic in the first trimester. We studied their nuchal translucency (NT) measurements at 12-13 weeks of gestation. METHODS: Nuchal translucency was measured prospectively in fetuses at risk of homozygous alpha-thalassemia-1. Measurements of those fetuses subsequently confirmed to be affected by homozygous alpha-thalassemia-1 but with a normal karyotype were compared to those of 440 controls. The controls were from the general obstetric population who had NT measurements at 12 or 13 weeks with known normal outcome. All the NT measurements were expressed as multiples of the median (MoM) for the gestational day. RESULTS: Between 1996 and 1998, 94 at-risk pregnancies were studied. Of these, 32 were subsequently confirmed to be affected by homozygous alpha-thalassemia-1. Chromosome study was not carried out in three cases and these were excluded from the analysis. Nuchal translucency MoMs for cases and controls were found to fit a log Gaussian distribution. The log means (standard deviation) for case and control NT MoM were 0.075 (0.156) and -0.0019 (0.091), respectively. The median NT MoM (95% CI) for cases was 1.19 (1.08-1.62) and was significantly higher than that of the controls (p < 0.001). However, there was extensive overlap of NT between cases and controls. CONCLUSION: Overall, there was a 19% increase in NT MoM in fetuses affected by homozygous alpha-thalassemia-1. This represents a difference of only 0.3-0.4 mm, which is clinically insignificant. This finding indirectly suggests that the increased NT in trisomic fetuses cannot be explained by fetal anemia. Conversely, the presence of increased NT in a fetus at risk of homozygous alpha-thalassemia-1 should alert one to the possibility of chromosomal abnormality rather than being attributed to fetal anemia.  (+info)

Alpha-thalassemia is a fairly common blood disorder that results in reduced amounts of hemoglobin, the protein in red blood cells that carries oxygen to cell in the body. This lowers the amount of oxygen that cells receive, causing various health problems, including anemia. There are two types of alpha-thalassemia that can cause serious health problems and two types that can cause mild symptoms. The most serious is called hemoglobin Bart. Fetuses affected with hemoglobin Bart usually do not survive beyond the newborn period. While still in the uterus, they experience health complications, including swelling, fluid buildup around the organs, heart defects and genital abnormalities. The mothers of these fetuses experience health complications including preeclampsia, (extreme hypertension), excessive amniotic fluid or reduced amniotic fluid, bleeding in the genital tract, and premature delivery. Due to the lack of very effective treatment and severe complications, termination of these pregnancies ...
Alpha-thalassemia is very common throughout all tropical and subtropical regions of the world. In Southeast Asia and the Mediterranean regions, compound heterozygotes and homozygotes may have anemia that is mild to severe (hemoglobin [Hb] H disease) or lethal (Hb Barts hydrops fetalis). We have developed a reliable, single-tube multiplex-polymerase chain reaction (PCR) assay for the 6 most frequently observed determinants of alpha-thalassemia. The assay allows simple, high throughput genetic screening for these common hematological disorders. (Blood. 2000;95:360-362)
X-linked alpha thalassemia mental retardation (ATR-X) syndrome is associated with profound developmental delay, facial dysmorphism, genital abnormalities, and alpha thalassemia. Patients with ATR-X syndrome frequently present with gastrointestinal problems, in particular feeding difficulties, regurgitation and vomiting, abdominal pain, distension, and chronic constipation. Parental reports of prolonged food refusal and distress in these children are common and although these episodes are suspected to be gastro-intestinal in origin they are rarely investigated. Death in early childhood from aspiration of vomitus or from pneumonia presumed to be secondary to aspiration has been recorded in a number of ATR-X cases. In this report we review the gastrointestinal phenotype of ATR-X syndrome in 128 cases. We also demonstrate that in two siblings, regurgitation was secondary to gastric pseudo-volvulus, a condition in which the stomach does not have a normal system of peritoneal ligaments and changes position
We will develop a simple PCR method to diagnosis alpha-thalassemias.

Four main conditions resulting from deletion or inactivation (nondeletion mutants) of one, two, three, or all four alpha-globin genes are recognized. Carriers of alpha0-thalassemia (two deleted alpha-globin genes, ie, alpha-thalassemia trait) show microcytosis, hypochromia, and normal percentages of HbA2 and HbF, carriers of alpha+-thalassemia (one deleted or nonfunctional alpha-globin gene, ie, alpha-thalassemia silent carrier) have either a silent hematologic phenotype or present with a moderate thalassemia-like hematologic picture. Two are the alpha-thalassemia clinically significant forms: Hb Bart hydrops fetalis syndrome and HbH disease (four and three deleted or nonfunctional alpha-globin genes, respectively). Hb Bart hydrops fetalis syndrome is the most severe form, characterized by fetal onset of generalized edema, pleural and pericardial effusions, and severe hypochromic anemia, in the absence of ABO or Rh blood group incompatibility. Death usually occurs in the neonatal period. HbH ...

N2 - This study on erythrocytes in hemoglobin H (Hb-H) disease reveals that unstable Hb-H is bound to membranes to a greater extent, especially when it forms methemoglobin or is precipitated as an inclusion body. The methemoglobin content of these erythrocytes is elevated in spite of a higher activity of NADH-methemoglobin reductase. The ATPase activity is doubled and ATP is presumably used for phosphorylation of membrane proteins, which leads to cross-linking of membrane proteins. This assumption could be supported by the observed decrease in non-electrolyte permeability, by increased binding of hemoglobin to the membrane, and polymerisation of membrane proteins detected by SDS-polyacrylamide gel electrophoresis. By means of electron microscopy, it could also be shown that the inclusion bodies are bound ...
Alpha thalassemia carrier. Two alpha chain genes are deleted. Alpha thalassemia minor or alpha thalassemia-1 trait are other terms for this condition. If both deleted genes are from the same #16 chromosome, it is called a cis deletion and is inherited from one parent. If instead one gene is missing from both #16 chromosomes, it is called a trans deletion and is inherited from both parents. This results in an anemia that is usually mild to moderate, but can be severe. When both parents are carriers of the cis deletion, there is a one in four, or 25 percent, chance with each pregnancy, to have a baby with alpha thalassemia major. Identifying whether an alpha thallasemia carrier has the cis deletion versus two trans deletions requires testing by DNA (deoxyribonucleic acid) analysis. DNA testing is usually done from a blood sample and looks at the alpha chain genes on each #16 chromosome, to determine which are deleted. ...

Objective: To determine the utility of the mean corpuscular hemoglobin (MCH) as a screening modality for prenatal diagnosis of Alpha thalassemia (α-thalassemia) Methods: We reviewed eighty-eight charts of pregnant women in a large Community Health Center in Miami, Florida who underwent DNA analysis for α-globin gene mutations from June 2010 to February 2012 and compiled a database of each patients hemoglobin (Hb) electrophoresis, mean corpuscular volume (MCV), MCH and DNA analysis. Results: Forty-five of the 88 patients had α-globin gene mutations. Approximately nine (20%) of these patients had normal MCV (80-100 fL), normal Hb electrophoresis but low MCH (|27 |pg). All patients in our study were carriers of a single α-globin gene mutation. Conclusion: Results suggest that the MCH can be a valuable indicator for including in the screening for α-globin gene mutations in pregnant women. Further population-based studies should be conducted to determine if the addition of MCH in combination with the

Alpha-thalassemia X-linked mental retardation (ATR-X) syndrome is a rare genetic disorder associated with severe developmental delay, mental retardation and craniofacial dysmorphism. This syndrome is caused by mutations in the ATRX gene which encodes a member of the SWI/SNF family of chromatin remodeling proteins. ATR-X patients exhibit dwarfism and skeletal defects, including hand and foot deformities. I hypothesized that the skeletal deformities in ATR-X syndrome are due to a direct role of ATRX in the development of the skeleton. My objective was to characterise skeletal phenotypes observed in three animal models conditionally deficient for ATRX in different skeletal tissues. Mice lacking the Atrx gene in forelimb mesenchyme, cartilage, or bone were generated using the Cre-lox system with Cre-recombinase under control of Prx1, Col2a1 or Col1a2 promoters, respectively. Mice lacking ATRX in cartilage or bone displayed limited skeletal phenotypes and did not recapitulate the defects seen in ATR-X

The pathophysiology of the thalassemias can be traced to the deleterious effects of the globin-chain subunits that are produced in excess. In β-thalassemia, excess α chains cause damage to the red cell precursors and red cells and lead to profound anemia. This causes expansion of the ineffective marrow, with severe effects on development, bone formation, and growth. The major cause of morbidity and mortality is the effect of iron deposition in the endocrine organs, liver, and heart, which results from increased intestinal absorption and the effects of blood transfusion. The pathophysiology of the α-thalassemias is different because the excess β chains that result from defective α-chain production form β4 molecules, or hemoglobin H, which is soluble and does not precipitate in the marrow. However, it is unstable and precipitates in older red cells. Hence, the anemia of α-thalassemia is hemolytic rather than dyserythropoietic. ...

Hemoglobin Constant Spring is a variant of Hemoglobin in which a mutation in the alpha globin gene produces an alpha globin chain that is abnormally long. It is the most common nondeletional alpha-thalassemia mutation associated with hemoglobin H disease. The quantity of hemoglobin in the cells is low because the messenger RNA is unstable and some is degraded prior to protein synthesis. Another reason is that the Constant Spring alpha chain protein is itself unstable. The result is a thalassemic phenotype.

Thalassemia is a disorder of production of one of the proteins of hemoglobin. Hemoglobin is a protein in red blood cells and is responsible for the transport of oxygen to tissues. Hemoglobin is made up of two proteins, alpha globin and beta globin.. Normal hemoglobin has two alpha and two beta globin protein chains. A deficiency or absence of the alpha chain results in Alpha-thalassemia and a deficiency or absence of one or more of the beta chains results in Beta-thalassemia. Beta-thalassemia occurs in 1 in 25,000 births in north america.. The beta chain requires a gene from each parent to produce the correct quality and quantity of beta globin. If the gene from one parent is missing or incomplete, the child will develop Beta-thalassemia minor. If the gene from both parents is missing, the child will develop Beta-thalassemia major or Cooleys anemia.. Thalassemia minor results in a microcytic red cell but otherwise there are no other sequelae. Thalassemia major results hemolysis. Newborns with ...

ATRX is a centromeric heterochromatin binding protein belonging to the SNF2 family of helicase/ATPases with chromatin remodeling activity. Mutations in the human ATRX gene result in X-linked alpha-thalassaemia with mental retardation (ATRX) syndrome and correlate with changes in methylation of repetitive DNA sequences. We show here that ATRX also functions to regulate key stages of meiosis in mouse oocytes. At the germinal vesicle (GV) stage, ATRX was found associated with the perinucleolar heterochromatin rim in transcriptionally quiescent oocytes. Phosphorylation of ATRX during meiotic maturation is dependent upon calcium calmodulin kinase (CamKII) activity. Meiotic resumption also coincides with deacetylation of histone H4 at lysine 5 (H4K5 Ac) while ATRX and histone H3 methylated on lysine 9 (H3K9) remained bound to the centromeres and interstitial regions of condensing chromosomes, respectively. Inhibition of histone deacetylases (HDACs) with trichostatin A (TSA) disrupted ATRX binding to the
I dont think its a simple trait kind of thing. There are a number of different gene polymorphs that confer some kind of resistance to the most severe symptoms and death from malaria. HbS or alpha-thalassaemia confer resistance to death from complications of P falciprum infections, but having both traits is either no different or even slightly worse than having no resistance marker at all. And resistence to complications doesnt mean that these individuals are immune to infection, only that they suffer fewer of the more severe symptoms of malaria. Im not sure its always clear why. I think its also true what others are saying, that only in the presence of significant malarial infection is there any advantage to having the sickle-cell trait. In the absence of any malaria, there should be at least a mild selection against it. I dont think the presence of the trait would, in itself, eliminate malaria since the life-cycle of the parasite is not interrupted in any way and transmission is still ...

Plasmodium falciparum infecting hemoglobin (Hb)H and/or Hb Constant Spring erythrocytes has higher resistance to artemisinin in vitro than when infecting normal erythrocytes. This is due to low drug accumulation of infected erythrocytes resulting from competition with uninfected variant erythrocytes, which have a higher accumulation capacity than genetically normal cells. Drug accumulation of the parasite was shown to be saturable and dependent on metabolic energy. The 50% inhibitory concentrations (IC50s) for the parasite in HbH/Hb Constant Spring erythrocytes were decreased when normal erythrocytes were added to the infected cells, and correspondingly, the IC50s in normal erythrocytes were increased when HbH/Hb Constant Spring erythrocytes were added to the infected cells.

Thalassaemia is a hereditary blood disorder caused by deficiency of the formation of alpha or beta globin chains that make up haemoglobin. According to WHO, there were approximately 5% of the worlds population carry the genetics and 370.000 babies were born with this disorder every year. The prevalence of Thalassaemia carrier in Indonesia 3-8%, the national prevalence of Thalassaemia in Indonesia is 0,1%. In North Sumatera, the prevalence of Alpha Thalassaemia 3,35% and 4,07% Beta Thalassaemia. This was a descriptive research using case series design, to determined the characteristics of Thalassaemia patients in RSU Sari Mutiara Medan 2012-2014. The population were 71 cases of Thalassaemia data which registered in RSUSari Mutiara Medan 2012-2014. This research showed that highest characteristics proportion of Thalassaemia patients at age group 6-11 (35,2%), male (57,7%), Javanese (64,8%), Islam (38,0%), come from outside of Medan (56,3%), pale as a major symptomp (63,4%), Thalassaemia Beta ...
The prevalence of alpha-thalassaemias is up to 5% in Hong Kong and up to 40% in some parts of South East Asia. Haemoglobin H consists of four betaglobin chains. Instead of the usual complement of four normal alphaglobin genes (two on each chromosome 16), people with haemoglobin H disease have only one. At the other three alphaglobin gene sites, they have either three deletions or two deletions and one mutation. Now, work in Hong Kong (New England Journal of Medicine2000;343:544-50) has shown that those with a mutation have more severe disease but iron overload is equally a problem in both types.. Eight of 13 American and four of five French boys with cerebral X-linked adrenoleukodystrophy survived bone marrow transplantation at ages 5 to 11 years and were followed for five to ten years (Lancet2000;356:713-18). Verbal intelligence remained normal in 11 and non-verbal abilities remained stable or improved in seven. Eight showed continuing demyelination on magnetic resonance imaging (MRI) but later ...
Beta thalassemias (β thalassemias) are a group of inherited blood disorders. They are forms of thalassemia caused by reduced or absent synthesis of the beta chains of hemoglobin that result in variable outcomes ranging from severe anemia to clinically asymptomatic individuals. Global annual incidence is estimated at one in 100,000. Beta thalassemias are caused by mutations in the HBB gene on chromosome 11, inherited in an autosomal recessive fashion. The severity of the disease depends on the nature of the mutation. HBB blockage over time leads to decreased beta-chain synthesis. The bodys inability to construct new beta-chains leads to the underproduction of HbA. Reductions in HbA available overall to fill the red blood cells in turn leads to microcytic anemia. Microcytic anemia ultimately develops in respect to inadequate HBB protein for sufficient red blood cell functioning. Due to this factor, the patient may require blood transfusions to make up for the blockage in the beta-chains. ...
Background: Hypercoagulability in splenectomized patients with thalassemia intermedia (TI) has been extensively evaluated. However, clinical and laboratory characteristics of patients who eventually develop overt thromboembolic events (TEE) are poorly studied. Patients-Methods: Three Groups of TI patients (n = 73 each) were retrospectively identified from a registry involving six centers across the Middle East and Italy: Group I, all splenectomized patients with a documented TEE; Group II, age- and sex-matched splenectomized patients without TEE; and Group III, age- and sex-matched nonsplenectomized patients without TEE. Retrieved data included demographics, laboratory parameters, clinical complications, and received treatments that may influence TEE development, and reflected the period prior to TEE occurrence in Group I. Results: The mean age of Group I patients at development of TEE was 33.1 ± 11.7 years, with a male to female ratio of 33:40. TEE were predominantly venous (95percent) while ...

Doctors help you with trusted information about Hearing Loss in Thalassemia: Dr. Roberts on thalassemia deafness: A person can marry anyone they like. From a thalassemia perspective, and assuming your Alpha thal trait is in cis, your child has a 50/50 chance of being Alpha thal trait vs. Normal and a 50/50 chance of being beta thal trait vs. Normal. Given there is consideration of inheriting two distinct trait states, it would be prudent to sit with a genetic counselor to understand the implications clearly.

The prevalence of human red blood cell (RBC) polymorphisms is high in areas of intense Plasmodium falciparum transmission, and individuals carrying these genetic traits are believed to be partially protected against severe malaria. However, it remains uncertain how RBC polymorphisms affect the susceptibility to uncomplicated malaria. We compared the risk of suffering from febrile, uncomplicated malaria between individuals carrying three common RBC polymorphisms (sickle cell trait, alpha+-thalassemia, and glucose-6-phosphate-dehydrogenase deficiency) and controls. The study was performed in an area of intense malaria transmission where 202 individuals 0-19 years of age were monitored clinically for a period of 6 months. RBC polymorphisms were assessed with molecular methods, and plasma antibodies to P. falciparum variant surface antigens (anti-VSA IgG) and glutamate-rich protein (anti-GLURP IgG) were measured with flow cytometry and ELISA assays, respectively. Regression analyses showed that alpha+
Thalassaemia drug. Bottle of the chelating agent Desferal (deferoxamine). A chelating agent removes heavy metals. In this case it removes excess iron from the blood. This is a common condition in patients who have to undergo regular blood transfusions, for example patients with thalassaemia. Thalassaemia is an inherited condition where the red blood cells are fragile and easily damaged. For chronic conditions like thalassaemia, the drug is infused gradually over several hours daily, by subcutaneous injection. Desferal can also be used to treat iron and aluminium poisoning. The use of Desferal is preferred to other chelating agents, due to fewer side-effects. - Stock Image M625/1582
Iron overload was found to be the major cause of disability in Chinese HbH disease patients although they were not on regular blood transfusion. The transferrin receptor 2 (TFR2) and hereditary hemochromatosis (HFE) genes were examined to see if inheritance of these gene defects may be a possible cause of iron overload in 45 HbH patients. A novel intronic (IVS6 (+6) T→A) mutation of the TFR2 gene was identified in one patient, and six others were found to carry a known missense mutation (exon 5, I238M) that was also present in one normal control subject. One HbH patient and one normal control carried the H63D mutation of the HFE gene. Since only eight out of 45 iron-overloaded HbH patients carry a defect in the TFR2 or HFE gene in the heterozygote state and their iron loading status was comparable to the matched controls without such defects, it would appear that the accumulation of excess iron in HbH disease is more likely a result of increase dietary absorption secondary to ineffective ...
We report red cell indices and haemoglobin (Hb)A2 levels in Sardinian children with heterozygous beta 0-thalassaemia and in normal controls aged 6 months to 12 years. Iron-deficient children and those with haematological findings indicative of alpha-thalassaemia were excluded. As in adult carriers, these subjects have significantly increased mean red cell counts and significantly reduced mean Hb levels, mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), haematocrit, and mean corpuscular haemoglobin concentration. From 66 to 76% of the heterozygous beta 0 thalassaemia children examined were anaemic. MCH and MCV were within the normal range in 2.8% of these children. Serum ferritin levels showed no difference from those of normal controls.. ...
