Deletion of a region that is a candidate for the difference between the deletion forms of hereditary persistence of fetal hemoglobin and deltabeta-thalassemia affects beta- but not gamma-globin gene expression. (1/992)

The analysis of a number of cases of beta-globin thalassemia and hereditary persistence of fetal hemoglobin (HPFH) due to large deletions in the beta-globin locus has led to the identification of several DNA elements that have been implicated in the switch from human fetal gamma- to adult beta-globin gene expression. We have tested this hypothesis for an element that covers the minimal distance between the thalassemia and HPFH deletions and is thought to be responsible for the difference between a deletion HPFH and deltabeta-thalassemia, located 5' of the delta-globin gene. This element has been deleted from a yeast artificial chromosome (YAC) containing the complete human beta-globin locus. Analysis of this modified YAC in transgenic mice shows that early embryonic expression is unaffected, but in the fetal liver it is subject to position effects. In addition, the efficiency of transcription of the beta-globin gene is decreased, but the developmental silencing of the gamma-globin genes is unaffected by the deletion. These results show that the deleted element is involved in the activation of the beta-globin gene perhaps through the loss of a structural function required for gene activation by long-range interactions.  (+info)

A new alkali-resistant hemoglobin alpha2J Oxford gammaF2 in a Sicilian baby girl with homozygous beta0 thalassemia. (2/992)

A 10-mo-old baby girl with homozygous beta0 thalassemia and alphaJOxford, presenting the clinical picture of homozygous beta thalassemia is described. Hemoglobin electrophoresis showed three bands: the first two with the mobilities of hemoglobin Hb A2 (1%) and Hb F (69%), respectively, the third migrating a little faster than Hb A (30%). About 30% of her alpha chains were J Oxford which, bound to her gamma chains, produced a new alkali-resistant hemoglobin, alpha2 J Oxford gamma F2, which has not been described previously. Hemoglobin synthesis in vitro showed the absence of beta chain synthesis and an alpha/non-alpha ratio of 2. The patient's father was heterozygous for both the Hb J Oxford and beta0 thalassemia genes, the mother a carrier of beta0 thalassemia; four other relatives were carriers of Hb J Oxford, and one was a carrier of beta thalassemia.  (+info)

'Common' uncommon anemias. (3/992)

Of the uncommon anemias, "common" types include the anemia of renal disease, thalassemia, myelodysplastic syndrome and the anemia of chronic disease. These conditions may be suggested by the clinical presentation, laboratory test values and peripheral blood smear, or by failure of the anemia to respond to iron supplements or nutrient replacement. The principal cause of the anemia of renal disease is a decreased production of red blood cells related to a relative deficiency of erythropoietin. When treatment is required, erythropoietin is administered, often with iron supplementation. In the anemia of chronic disease, impaired iron transport decreases red blood cell production. Treatment is predominantly directed at the underlying condition. Since iron stores are usually normal, iron administration is not beneficial. Thalassemia minor results from a congenital abnormality of hemoglobin synthesis. The disorder may masquerade as mild iron deficiency anemia, but iron therapy and transfusions are often not indicated. In the myelodysplastic syndrome, blood cell components fail to mature, and the condition may progress to acute nonlymphocytic leukemia. The rate of progression depends on the subtype of myelodysplasia, but the leukemia is usually resistant to therapy.  (+info)

Hormonal changes in thalassaemia major. (4/992)

Patients with severe thalassaemia major suffer endocrine and other abnormalities before their eventual death from iron overload due to repeated blood transfusions. The endocrine status of 31 thalassaemic patients aged 2-5 to 23 years was investigated. Exact data were available on the rate and duration of blood transfusion in all of them and in many the liver iron concentration was also known. Although the patients were euthyroid, the mean serum thyroxine level was significantly lower, and the mean thyrotrophic hormone level significantly higher, compared with the values found in normal children. Forty oral glucose tolerance tests with simultaneous insulin levels were performed in 19 children, of whom 5 developed symptomatic diabetes and one had impaired tolerance. Previous tests on all 6 patients were available and some showed raised insulin levels possibly due to insulin resistance. 2 patients had clinical hypoparathyroidism and are described. The parathyroid hormone levels determined by radioimmunoassay in 25 patients were below the mean for the age group in all and outside the reference range in 16. Nonfasting plasma calcium levels were not reduced. Puberty was delayed in some patients. Concentrations of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) measured in urine from 7 girls and 5 boys showed considerable variation. In the boys there was an overall tendency for FSH and LH excretion to be low with regard to age, but with respect to puberty rating FSH exretions were normal or low and LH normal or raised. The girls showed a tendency for LH but not FSH excretion to be raised in relation to puberty rating. The severity of the endocrine changes was related to the degree of iron loading and is discussed in relation to previous work in which the iron loading has rarely been accurately indicated nor parathyroid status assessed.  (+info)

Birth of healthy children after preimplantation diagnosis of thalassemias. (5/992)

BACKGROUND: Preimplantation genetic diagnosis (PGD) allows couples at risk of having children with thalassemia to ensure the healthy outcome of their pregnancy. METHODS: Seventeen PGD clinical cycles were initiated for Cypriot couples at risk of having children with different thalassemia mutations, including IVSI-110, IVSI-6, and IVS II-745. Unaffected embryos for transfer were selected by testing oocytes, using first and second polar body (PB) removal and nested polymerase chain reaction analysis followed by restriction digestion. RESULTS: Unaffected embryos were selected in 16 of 17 PGD cycles. Of 166 oocytes studied from these cycles, 110 were analyzed by sequential analysis of both the first and the second PB, resulting in preselection and transfer of 45 unaffected embryos. This resulted in seven pregnancies and in the birth of five healthy thalassemia-free children. The embryos predicted to have inherited the affected allele were not transferred. Analysis of these embryos confirmed the PB diagnosis. CONCLUSIONS: Sequential first and second PB testing of oocytes is reliable for PGD of thalassemia and is a feasible alternative to prenatal diagnosis in high-risk populations.  (+info)

Further evidence of a quantitative deficiency of chain-specific globin mRNA in the thalassemia syndromes. (6/992)

Formamide gel electrophoresis separates the mRNA fraction from reticulocyte polyribosomes of adult humans into two major RNA species with migratory rates identical to those of the alpha- and beta-globin mRNAs of the rabbit. That these two RNAs of human origin are the globin mRNAs is further supported by the deficiency of the presumed beta mRNA in reticulocyte polyribosomes of fetuses and premature infants, whose cells make gamma chains in preference to beta chains. The globin mRNAs of reticulocyte polyribosomes from patients with hematological disorders were estimated by scanning the stained formamide gels. In contrast to individuals with either hemolytic anemia without hemoglobinopathy or sickle cell anemia who had beta mRNA to alpha mRNA ratios of approximately one, a patient with Hb S-beta-thalassemia had a ratio of beta mRNA to alpha mRNA of 0.75 while two subjects with homozygous beta-thalassemia had severe deficiencies of beta mRNA. Conversely, a patient with alpha-thalassemia (Hb H disease) had a ratio of beta mRNA to alpha mRNA on reticulocyte polyribosomes of 6. These data provide further evidence of a quantitative deficiency of chain-specific globin mRNA in patients with the thalassemia syndromes.  (+info)

Coexistence of two functioning T-cell repertoires in healthy ex-thalassemics bearing a persistent mixed chimerism years after bone marrow transplantation. (7/992)

Bone marrow transplantation (BMT) from an HLA-identical donor is an established therapy to cure homozygous beta-thalassemia. Approximately 10% of thalassemic patients developed a persistent mixed chimerism (PMC) after BMT characterized by stable coexistence of host and donor cells in all hematopoietic compartments. Interestingly, in the erythrocytic lineage, close to normal levels of hemoglobin can be observed in the absence of complete donor engraftment. In the lymphocytic lineage, the striking feature is the coexistence of immune cells. This implies a state of tolerance or anergy, raising the issue of immunocompetence of the host. To understand the state of the T cells in PMC, repertoire analysis and functional studies were performed on cells from 3 ex-thalassemics. Repertoire analysis showed a profound skewing. This was due to an expansion of some T cells and not to a collapse of the repertoire, because phytohemagglutinin stimulation showed the presence of a complex repertoire. The immunocompetence of the chimeric immune systems was further established by showing responses to alloantigens and recall antigens in vitro. Both host and donor lymphocytes were observed in the cultures. These data suggest that the expanded T cells play a role in specific tolerance while allowing a normal immune status in these patients.  (+info)

Relative numbers of human globin genes assayed with purified alpha and beta complementary human DNA. (8/992)

Purified alpha and beta globin complementary DNAs (cDNAs) have been separated from total radioactively labeled human globin cDNA using mRNA purified from liver of a hydrops fetalis (alpha thalassemia). The beta cDNA hybridizes to the hydrops fetalis mRNA while the alpha cDNA remains single-stranded. the purified alpha and beta cDNAs were assayed for their purity by their hybridization to mRNA prepared from reticulocytes of nonthalassemia, alpha thalassemia, and beta thalassemia subjects. The results indicate that the separated cDNAs are selective in hybridization to alpha or beta globin mRNAs, respectively. The previously reported deficiency of globin mRNA in thalassemia cells has been confirmed with these purified cDNAs. The purified alpha and beta cDNAs were hybridized to cellular DNA to non-thalassemia, beta+ thalassemia, and hydrops fetalis (alpha thalassemia) DNA. The alpha cDNA hybridized to hydrops fetalis liver DNA to a much lower extent that beta cDNA, confirming the previously reported deletion of alpha globin genes in hydrops fetalis. By contrast, both the alpha and beta DNA probes hybridized to the same extent to spleen DNA from non-thalassemia and from beta+ thalassemia patients. Between two and five globin genes in non-thalassemia and beta+ thalassemia DNA hybridize to beta cDNA and one to five to alpha cDNA. These studies indicate that in beta+ thalassemia, there is no detectable deletion in beta globin genes. The genetic defect in beta+ thalassemia appears to be due to either repression of transcription of beta globin genes or abnormal processing of beta globin mRNA.  (+info)

Correlation analysis between the hematological parameters mean corpuscular hemoglobin (MCH) and mean corpuscular volume (MCV) for thalassemia screening in large population was discussed. A total of 4920 peripheral blood samples of reproductive age persons were collected from Guangdong province of China. The hematological parameters MCH and MCV values of samples were first measured, and then the DNA analyses for thalassemia were conducted. All samples were composed by 4463 non-thalassemia and 457 thalassemia, and among 457 thalassemia samples, 311 were α-thalassemia, 133 were β-thalassemia, and 13 were α & β-thalassemia. In accordance with non-thalassemia, thalassemia, α-thalassemia, β-thalassemia, α & β-thalassemia and the entire group itself, a total of six sample groups were divided. The corresponding correlation coefficients between the measured MCH and MCV values for the six sample groups were 0.880, 0.968, 0.966, 0.962, 0.980 and 0.965 respectively.

The Thalassemia Foundation was founded in 1982 by Angela Polsinelli, the parent of a patient, with the help of a few other parents and patients. It was created because there was a large number of thalassemia patients in the Toronto area, but there was no structured association available. Dr. Freedman asked Angela if she would start an organization, and she agreed. The Cooleys Anemia Foundation in New York City was instrumental in teaching Angela the ropes in regards to setting up an organization in Ontario.. The original name for the Foundation was the Ontario Thalassemia Association. The Association made its own guidelines and objectives. It became legally incorporated on December 13, 1988, under the name Ontario Thalassemia Foundation.. On May 10, 1999, the Foundations name was changed to the Thalassemia Foundation of Canada to better reflect its Canada-wide membership and the work it does on behalf of thalassemia patients at a national level. The Foundation communicates with the thalassemia ...

Delta beta (δβ)-thalassemia results from a deletion in both the delta and beta genes on chromosome 11. The gamma genes on the affected chromosome increase their production of gamma globin, thereby increasing the amount of hemoglobin F (HbF). δβ-Thalassemia heterozygotes clinically show characteristics of thalassemia minor. However, homozygous δβ-thalassemia may give a clinical picture of thalassemia intermedia with a mild anemia.. A 12-month-old boy presented to the hematology outpatient department for evaluation of pallor and jaundice that had been for the past 2 months. He had no history of a blood transfusion. His family history was insignificant for congenital anemia. His parents had a consanguineous marriage. Physical examination revealed pallor and palpable spleen 2 cm below the left costal margin. Other examination findings were unremarkable. A complete blood count (CBC) revealed an Hb level of 8.0 g/dL, WBC count of 8.9×109/L, and platelet count of 341×109/L (Table 1). A ...
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. ...
Background: Recent advances in the management of thalassemia have significantly improved life expectancy and quality of life of patients with this hemoglobinopathy, with a consequent increase in their reproductive potential and desire to have children. Design and Methods: We describe the methods of conception and delivery, as well as the course and outcome of pregnancy including transfusions, iron overload and chelation in 46 women with thalassemia major (58 pregnancies) and in 11 women with thalassemia intermedia (17 pregnancies). Conception was achieved after gonadotrophin-induced ovulation in 33 of the women with thalassemia major and spontaneously in all of those with thalassemia intermedia. Results: Among the women with thalassemia major, 91% of the pregnancies resulted in successful delivery of 45 singleton live-born neonates, five sets of twins and one set of triplets. No secondary complications of iron overload developed or worsened during pregnancy. When considering only the singleton ...

Patients with homozygous thalassemia may have either a severe phenotype which is usually transfusion dependent or a milder form that is thalassemia intermedia. The two main factors that determine cardiac disease in homozygous ? thalassemia are the high output state that results from chronic tissue hypoxia, hypoxia-induced compensatory reactions and iron overload. The high output state playing a major role in thalassaemia intermedia and the iron load being more significant in the major form. Arrhythmias, vascular involvement that leads to an increased pulmonary vascular resistance and an increased systemic vascular stiffness and valvular abnormalities also contribute to the cardiac dysfunction in varying degrees according to the severity of the phenotype. Endocrine abnormalities, infections, renal function and medications can also play a role in the overall cardiac function. For thalassaemia
Hamid et al. 2016. Thalassemia minor is known to be a hereditary disease involving affected globin chains. In Thalassemia minor, the fetus inherits haemoglobin genes during fertilization, each from the mother and the father, respectively.
Background: Thalassemia is the name of a group of genetic blood disorders. To understand how thalassemia affects the human body, you must first understand a little about how blood is made. Hemoglobin is the oxygen-carrying component of the red blood cells. It consists of two different proteins, an alpha and a beta. If the body doesnt produce enough of either of these two proteins, the red blood cells do not form properly and cannot carry sufficient oxygen. The result is anemia that begins in early childhood and lasts throughout life. Since thalassemia is not a single disorder but a group of related disorders that affect the human body in similar ways, it is important to understand the differences between the various types of thalassemia. Aim: The aim of the research was to determine the prevalence of thalassemia and its characteristics among patients of a thalassemia center at Ibn-Alatheer hospital, Mosul /Iraq. Methods: This study was conducted on 86 cases over a period of one month from ...
Alpha thalassemia causes mild anemia and is found in many ethnic groups. Usually it is found in regions where malaria is endemic. We have found that alpha thalassemia is common in Ashkenazim, whose countries of origin are in temperate climates.. We are analyzing the alpha globin polymorphisms to determine the haplotypes of individuals of many ethnic groups and will compare to try to define the origin of thalassemia in these individuals of European extraction. ...

Alpha thalassemia is an inherited blood disorder. This means it is passed down through the parents genes. It causes anemia in affected children. Anemia is a low red blood cell or low hemoglobin level. Hemoglobin is the part of red blood cells. It carries oxygen to organs, tissues, and cells. Alpha thalassemia affects the production of hemoglobin. There are different types of thalassemia. The severity of anemia depends on the type the child has. ...
Treatment of patients with beta thalassemia in North America has altered dramatically during the past 40 years, with improvements in transfusion therapy and introduction of iron chelation therapy. Thalassemia patients now enjoy an increased life expectancy to the fifth and sixth decades of life, with fertility and childbearing becoming important issues. Data regarding this important topic remain limited, without clear data regarding iron control including serial assessment of hepatic iron concentration, the need for assistance in becoming pregnant, and use of iron chelating agents during pregnancy. As the life expectancy increases and overall health improves in thalassemia, clear data on fertility, pregnancy complications, and the effect of pregnancy on maternal health in thalassemia patients are necessary since these will have a direct impact on patient care, quality of life, and patient expectations ...
Sinasi Nasih Ozsoylu. Did the proband have thalassemia intermedia or severe thalassemia trait?. Turk J Hematol. 2012; 29(1): 99- ...
Causes. Thalassemia is a genetic disorder, is caused by mutations in the DNA of cells that make hemoglobin. The mutations associated with thalassemia are passed from parents to children. The mutations that cause thalassemia disrupt the normal production of hemoglobin and cause low hemoglobin levels and a high rate of red blood cell destruction.. Thalassemia occurs when there is a defect in a gene that helps control production of one of these proteins and if the genes responsible do not produce enough of alpha or beta chains, the red cells cannot carry hemoglobin properly. The result would be anemia which starts in early childhood and lasts all through life.. Types. The type of thalassemia you have depends on the number of gene mutations you inherit from your parents and which part of the hemoglobin molecule is affected by the mutations. Hemoglobin molecules are made of alpha and beta chains that can be affected by mutations. Where the genes do not produce enough alpha chains, the condition is ...
This pilot study is investigating combination treatment of deferiprone and deferasirox for improving iron excretion in patients with beta thalassemia.
Thalassemia is a genetic blood disorder that causes an individuals body to create an abnormal form or an inadequate amount of haemoglobin, which directly results in the destruction of a large number of red blood cells in the body, thus the individual develops anaemia. In order to address the need for awareness on this subject matter, Dr. Nita Munshi, Director of the Department of Laboratories at Ruby Hall Clinic group of Hospitals, President of Thalassemia Society, Pune conducted a Thalassemia awareness session at SCIT on November 30, 2019.. Dr. Nita, who has devoted her career towards helping and treating patients of thalassemia, explained in detail about the actual causes of thalassemia, what it does to ones body, the treatments that are currently in practice for this disease and the intense pain and inconvenience and patients and their families have to go through.. This entire ordeal is financially draining on the families involved, as the patients require monthly or weekly blood ...
Patients with severe thalassaemia major suffer endocrine and other abnormalities before their eventual death from iron overload due to repeated blood transfusions. The endocrine status of 31 thalassaemic patients aged 2-5 to 23 years was investigated. Exact data were available on the rate and duration of blood transfusion in all of them and in many the liver iron concentration was also known. Although the patients were euthyroid, the mean serum thyroxine level was significantly lower, and the mean thyrotrophic hormone level significantly higher, compared with the values found in normal children. Forty oral glucose tolerance tests with simultaneous insulin levels were performed in 19 children, of whom 5 developed symptomatic diabetes and one had impaired tolerance. Previous tests on all 6 patients were available and some showed raised insulin levels possibly due to insulin resistance. 2 patients had clinical hypoparathyroidism and are described. The parathyroid hormone levels determined by ...
Thalassemia is a genetic blood disorder that severely affects the patients bone marrow. Know more about types of Thalassemia, symptoms and cure for Thalassemia from our experts.
Treatment of the inherited blood disorder thalassemia depends upon the level of severity. For mild forms of the condition, advice and counseling are often all that are necessary. For more severe forms, treatment may consist in blood transfusion; chelation therapy to reverse iron overload, using drugs such as deferoxamine, deferiprone, or deferasirox; medication with the antioxidant indicaxanthin to prevent the breakdown of hemoglobin; or a bone marrow transplant using material from a compatible donor, or from the patients mother. Population screening has had some success as a preventive measure. Mild thalassemia : patients with thalassemia traits do not require medical or follow-up care after the initial diagnosis is made. Patients with β-thalassemia trait should be warned that their condition can be misdiagnosed for the common Iron deficiency anemia. They should eschew empirical use of Iron therapy; yet iron deficiency can develop during pregnancy or from chronic bleeding. Counseling is ...

The alpha thalassemia (α-thalassemia) syndromes are a group of hereditary anemias of varying clinical severity. They are characterized by reduced or absent production of 1 or more of the globin chains of which human hemoglobin is composed.
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 ...
Glyco-metabolic status was evaluated in 29 pubertal homozygous thalassaemics aged from 17 to 42 years and in 12 age-matched healthy subjects. Diagnosis of diabetes mellitus was assessed in 4 patients (13.8%), who became diabetic after the age of 18 years. With respect to controls non-diabetic patients exhibited significantly higher fasting plasma glucose levels and more sustained glycemic responses to oral glucose tolerance test, whereas their overall insulin output was significantly lower. Moreover non-diabetic thalassaemic patients showed a clear reduction of both beta-cell function and insulin resistance indices (HOMA model). In conclusion our data show a high prevalence of diabetes but do not support the existence of an insulin resistant status in thalassaemia major, at least in adulthood.. ...

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
Thalassemia is a group of genetic blood disorders that affect approximately 1,000 individuals in the United States. The most severe of these disorders is Cooleys Anemia. People with thalassemia have a genetic defect of their red blood cells that affects the cells ability to produce normal hemoglobin. Red blood cells use hemoglobin to carry oxygen to tissues. As a result of the defect, most forms of thalassemia produce a chronic, lifelong anemia that begins in early childhood and often must be treated with frequent transfusions.
地中海贫血(thalassemia)被认为是一种遗传性溶血性疾病,在中国常见于南方。世界上约5%人口是镰状细胞病或地中海贫血基因携带者,其中超过141万人生活在中国广西省。由于中国的社会保障和医疗体系仍在发展,许多贫困地区的患者常常难以负担医疗费用,一个地中海贫血儿童每月用以维系生命的输血和服药费用至少需要2000元(2014)。据统计,中国只有不到4.5%的地贫患者能活过15岁。更严重的局面是,随着国内人口迁移,这种疾病正显示出加速蔓延的趋势。. -2015.

The cost of keeping one child with thalassemia alive is about 300 dollars per month, ...
The alpha thalassaemias are the commonest known human genetic disorders. Although they have almost certainly risen to their current frequencies through natural selection by malaria, the precise mechanism of malaria protection remains unknown. We have investigated the characteristics of red blood cells (RBCs) from individuals heterozygous for alpha(0)thalassaemia (-/alphaalpha) from a range of perspectives. On the basis of the hypothesis that defects in membrane transport could be relevant to the mechanism of malaria protection, we investigated sodium and potassium transport and the activity of the Plamodium falciparum-induced choline channel but found no significant differences in -/alphaalpha RBCs. Using flow cytometry, we found that thalassaemic P. falciparum-infected RBCs (IRBCs) bound 44% more antibody from immune plasma than control IRBCs. This excess binding was abrogated by predigestion of IRBCs with trypsin but was not directed at the variant surface molecule PfEMP1. Furthermore, we found no

GAENSLER, LUCIO LUZZATTO & MICHEL SADELAIN The stable introduction of a functional -globin gene in haematopoietic stem cells could be a powerful approach to treat -thalassaemia and sickle-cell disease. Genetic approaches aiming to increase normal -globin expression in the progeny of autologous haematopoietic stem cells might circumvent the limitations and risks of allogeneic cell transplants. However, low-level expression, position effects and transcriptional silencing hampered the effectiveness of viral transduction of the human -globin gene when it was linked to minimal regulatory sequences. Here we show that the use of recombinant lentiviruses enables efficient transfer and faithful integration of the human -globin gene together with large segments of its locus control ...

n normal individual, hemoglobin consists of two alpha chains and two beta chains. Beta thalassemia is associated with point mutation of the beta globin chain of the hemoglobin of the chromosome 11. Beta thalassemia may present with reduced production o
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. ...
The Thalassaemia Society of India (TSI) also feels the need for such campaigns since lack of awareness is the only impediment in thalassaemia prevention.
Beta-thalassemia is due to a defect in the synthesis of the beta-globin chains, leading to alpha/beta imbalance, ineffective erythropoiesis, and chronic anemia. The spectrum of thalassemias is wide, with one end comprising thalassemia minor, which co

Tak province in the western region and Ranong province in the southern region are the 2 top 10 provinces of Thailand with malaria incidence in 2013. Most of the patients included in the study were Burmese, and the prevalence rate of P. vivax infection was found to be higher than P. falciparum infection with the ratio 1.5:1. The overall prevalence rate of thalassemia hemoglobinopathy in this group of populations was 36.7%. The most prevalent type Hb E (18.8%) is a common abnormal hemoglobin form of thalassemia which is distributed in Mediterranean, East Asia, India subcontinent, and Southeast Asia [16]. Hb E carriers in Thai (10-60%) and Burmese (11.4-60%) populations have been reported to vary markedly depending on the areas of investigation [17]. Results of the present study showed that Hb E is the most predominant form of thalassemia with prevalence rates of 2/12 (16.7%) and 17/89 (19.1%) in Thai and Burmese malaria patients, respectively. This was consistent with that previously observed in ...

Haemoglobin synthesis was studied in fetal blood samples obtained at 17 to 20 weeks gestation in 22 women at risk of carrying a fetus with homozygous beta-thalassaemia. A presumptive diagnosis of homozygous beta-thalassaemia was made in four cases, and the pregnancy was terminated. An inconclusive answer was obtained in one case, and the patient also chose to have her pregnancy terminated. Two fetuses were lost as a result of the procedure. Of the remaining 15 pregnancies, 13 proceeded to term and two to 36 weeks; in each case a normal infant or one heterozygous for beta-thalassaemia was delivered. Current efforts should be directed towards improving the blood sampling technology so that fetal blood sampling can be used widely in those countries where thalassaemia is a major problem. ...

We have studied the interaction of the alpha alpha alpha/alpha alpha gene arrangement with various beta globin genotypes (AA, AS, AC, SS and SC). Whereas this interaction has no detectable clinical or haematological effects in subjects with AA, SS or SC genotypes it is associated with a significantly increased level of Hb S or Hb C in heterozygotes for these variants. These findings indicate that the additional alpha globin gene in the alpha alpha alpha gene arrangement is functional.

AU - Hoffbrand, A V. AU - Wonke, B. PY - 1998/12. Y1 - 1998/12. N2 - Cooleys original description of beta-thalassaemia major included marked bone deformities as a characteristic feature. These were thought to be due to expansion of haemopoiesis attempting to compensate for the congenital anaemia. Regular blood transfusions from infancy prevents these skeletal problems. Nevertheless, symptoms due to bone disease frequently occur in adult patients. Osteoporosis has not previously been reported as a cause of severe morbidity in thalassaemia major. The present study shows a high prevalence of low bone mass among thalassaemia major patients and analyses the predisposing causes. Bone density scans were performed in 82 patients with transfusion-dependent beta thalassaemia. Factors known to be associated with ...
The left ventricular dimension and posterior wall dynamics were studied by computer assisted analysis of M mode echocardiography in 25 normal children (group 1) and 32 transfusion dependent children with beta thalassaemia major who had no evidence of heart failure (group 2). Twenty seven of those in group 2 remained well but five died of cardiac decompensation within 12 months. Compared with group 1, the left ventricular fractional shortening and ejection fraction were normal in those in group 2 who survived but diminished in those who died. Evaluation of left ventricular dimension and posterior wall dynamics during systole (peak shortening rate, peak velocity of circumferential fibre shortening, and peak posterior wall thickening rate) showed similar findings in that only the group who died had abnormal values. The left ventricular dimension and posterior wall diastolic dynamics (peak relaxation rate, normalised peak relaxation, peak wall thinning, and normalised peak wall thinning rate), ...

Beta thalassemia is caused by mutations in the beta chain of the hemoglobin molecule. There are two types of Beta Thalassemia: beta thalassemia major (Cooleys anemia) - both (two) beta chain genes have deletions, causing the most severe type of beta thalassemia. Thalassemia major patients need frequent blood transfusions and may not survive a normal lifespan. During the first one to two years of life, they can be pale, fussy, have a poor appetite, and have many infections. Without treatment, the spleen, liver, and heart become enlarged, and bones can become thin and brittle. A major problem is the build up of iron in the heart and other organs, resulting in heart failure for some patients in their teens or early 20s. halassemia minor or thalassemia trait - one beta gene has a deletion, resulting in anemia. Thalassemia minor is further divided into: thalassemia minima - person has few or no symptoms. thalassemia intermedia - person has moderate to severe anemia.. Biliary Atresia ...
Sickle beta plus thalassemia - Do beta thalassemia and sickle cell anemia always reduce life expectancy? Not if just 1 trait. Having either beta thalassemia trait or sickle cell trait is a mild condition and should not cause symptoms to the point of making a person frequently ill nor shortening life expectancy. Having beta thalassemia major or sickle cell disease, or both sickle cell trait and beta thalassemia trait, usually causes severe enough chronic disease symptoms to shorten lifespan an uncertain amount.
In cases of thalassemia major, infants are usually normal at birth but then become increasingly anemic over the next few months. If not treated, they will show signs of failure to thrive within the first year of life. Children maintain normal growth pattern if regular transfusions are received but can develop signs of iron overload by age 10 years if iron chelation are not used prophylactically. The first indication of iron overload is the absence of pubertal growth spurt and failure of menarche. Later onset anemia suggests intermedia subtype of β thalassemia. Beta Thalassemia Intermedia encompasses disorders with wide spectrum of clinical presentation. Spectrum of severity can range from those with haemoglobin level of 6 grams/deciliter (g/dL) with severe disability to asymptomatic cases with haemoglobin of 10-12 g/dL in mild phenotype of beta thalassemia intermedia. Iron overload in this category typically presents in the fourth decade of life. There is high incidence of pigmented gall ...
The most common severe hemoglobin disorder is related to mutations in the β-subunits and is thus termed β-thalassemia. If both genes are affected, symptoms are much more severe and the disease is then referred to as β-thalassemia major.. The defects in the genes result in ineffective formation of red blood cells and damage to existing red blood cells. As a result, β-thalassemia major patients typically present with life-threatening anemia within the first year of life and if left untreated will have a life expectancy of no more than three years. Other symptoms include jaundice, enlarged organs, misshapen bones and stunted growth.. There is currently no approved curative treatment for β-thalassemia major. Its main symptom, anemia, is treated through regular and lifelong red blood cell transfusions, which are generally needed every two to four weeks. However, this frequently leads to iron overload, which is the principal cause of mortality in β-thalassemia major patients. To control iron ...

Background: The protective effect of α-thalassemia, a common hematological disorder in Southeast Asia, against Plasmodium falciparum malaria has been well established. However, there are much less well understood the effect of α-thalassemia against P.vivax. Here, we aimed to investigate the proportion of α-thalassemia including the effect of α-thalassemia and HbE on the parasitemia of P.vivax in Southeast Asian malaria patients in Thailand.. Methods: A total of 210 malaria patients, admitted to the Hospital for Tropical Diseases, Thailand during 2011-2012, consist of 159 Myanmeses, 13 Karens, 26 Thais, 3 Mons, 3 Laotians, and 6 Cambodians were recruited. Plasmodium spp. and parasite densities were determined. Group of deletion mutation (--SEA, -α3.7, -α4.2deletion) and substitution mutation (HbCS and HbE) were genotyped using multiplex gap-PCR and PCR-RFLP, respectively.. Results: In our malaria patients, 17/210 homozygous and 74/210 heterozygous -α3.7 deletion were found. Only 3/210 ...

Patients with β thalassaemia major are dependent upon regular blood transfusions, and consequently are subjected to a large iron load. Accumulation of excess iron leads to heart failure. Iron chelation therapy can delay this process, but compliance is commonly poor. Severe cardiac failure in iron overloaded patients with β thalassaemia major has previously been reported as being invariably fatal.. A 21 year old man with β thalassaemia major was admitted with breathlessness. Examination revealed tachycardia, hypotension, and tachypnoea. He had a third heart sound, ankle oedema, raised venous pressure, smooth hepatomegaly, and dullness at the right base. Chest x ray showed cardiomegaly and a right pleural effusion. Ferritin was notably elevated (, 5000 μg/l). ECG showed sinus tachycardia. An echocardiogram (below left) showed severe left ventricular impairment (ejection fraction , 20%).. Despite diuretics the patient continued to decline. Inotrope and high dose desferroxiamine (70 mg/kg/day) ...
Hepatitis A and E virus (HAV and HEV) infections are acute and self-limited diseases that usually spread through oral-fecal route. Also, blood transfusion as a possible route of entrically transmitted hepatitis has been suggested. Hemophilia and thalassemia patients are highly at risk of transfusion-transmissible viruses (HBV, HCV, and HIV). Any superimposed infection with other viral hepatitis (in particular hepatitis A) cause active liver failure in hemophilia and thalassemia patients.The aim of this study is to consider seroprevalence of anti HAV and HEV antibodies (Ab) in thalassemia and hemophilia patients with chronic hepatitis C in Iran.In a cross-sectional study and under general census sampling, sera of 219 thalassemia and hemophilia patients infected with HCV were examined in Tehran Hepatitis Center (THC) between 2009 and 2010. Enzyme-linked immunisorbentassey (ELISA) was done to observe anti HAV and HEV IgG Ab. Patients were chosen from all provinces of Iran.Anti-HAV IgG antibodies were
Ancient DNA methodologies can be applied in the investigation of the genetics of extinct populations. A search for beta thalassemia mutations was performed on 49 Minoan individuals from the Bronze Age who were living in the island of Crete approximately 4000 Years Before Present (YBP). Standard precautionary measures were employed in the laboratory to ensure authenticity of the DNA extracted from the ancient bones, resulting in the successful analysis of DNA of 24 Minoans. DNA sequencing focused on the Intervening Sequence 1 (IVS-1) of the beta globin gene and its splicing junctions. 63% of the thalassemia mutations observed among modern Cretans reside in beta IVS-1. None of the Minoan individuals carried one of the IVS-1 mutations known to cause beta thalassemia; however, only one was expected to be observed if the average frequency of beta thalassemia heterozygotes in the Minoan population was the same with that of modern day Cretans (7.6%). One individual contained a C to G substitution in ...
α-Thalassemia major is the result of a two α-chain gene deletion. These deletions may be on same gene (-/αα, α0-thalassemia) described as cis-deletion or on different genes (-α/-α, α+-thalassemia) described as trans deletion. The CBC shows mildly reduced Hb level with low MCV and MCH. HbF and HbA2 within reference level. The presence of thalassemic indices in patient with normal HbA2 and HbF is often the basis for diagnosis of α-thalassemia major, particularly if family history is positive. ...
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.

Introduction. Thalassemia intermedia (TI) is a clinical designation often used to characterize individuals who are homozygous for beta-thalassemia genes but maintain hemoglobin levels of 6-9 g/dl without regular transfusions. The term TI has been used to describe the clinical and hematologic findings in patients whose disease is not as severe as that which characterizes homozygous beta-thalassemia, but is more severe than the heterozygous carrier.1 Hb Dhofar is a variant hemoglobin (beta[29 (GGC-GGT) gly-gly], beta[58 (CCT-CGT) pro-arg]) associated with a thalassemic phenotype and unique to the Sultanate of Oman. Clinical and hematological data suggest that this mutation behaves like a moderately severe beta (+) thalassemia allele resulting in a TI phenotype.2 The available options in the management of TI patients include splenectomy, transfusion therapy, iron chelation therapy and the use of cytotoxic drugs such as hydroxyurea to increase the Hb F level.3 We report of a 19 year old Omani male ...
The thalassemias, together with sickle cell anemia and its variants, are the worlds most common form of inherited anemia, and in economically undeveloped countries, they still account for tens of thousands of premature deaths every year. In developed countries, treatment of thalassemia is also still far from ideal, requiring lifelong transfusion or allogeneic bone marrow transplantation. Clinical and molecular genetic studies over the course of the last 50 years have demonstrated how coinheritance of modifier genes, which alter the balance of α-like and β-like globin gene expression, may transform severe, transfusion-dependent thalassemia into relatively mild forms of anemia. Most attention has been paid to pathways that increase γ-globin expression, and hence the production of fetal hemoglobin. Here we review the evidence that reduction of α-globin expression may provide an equally plausible approach to ameliorating clinically severe forms of β-thalassemia, and in particular, the very common
BACKGROUND: Thalassaemias pose an increasing problem for the Indian subcontinent and many Asian countries. We analysed the different types of thalassaemia in the Sri Lankan population, surveyed gene frequencies in schoolchildren, and estimated the burden of disease and requirements for its control. METHODS: We analysed blood samples from patients attending clinics in nine hospitals and defined the different types of beta thalassaemia by high-performance liquid chromatography (HPLC) and DNA analysis. The range of mutations was obtained by analysis of beta-globin genes. Capillary blood was obtained from schoolchildren from different parts of the island and analysed by HPLC to provide an approximate assessment of the carrier frequency of beta thalassaemia and haemoglobin E (HbE). To estimate the frequency of alpha thalassaemia the alpha-globin genotypes were also analysed when it was possible. FINDINGS: Blood samples were obtained from 703 patients with beta thalassaemia and from 1600 schoolchildren. The
Beta-thalassemia is due to a defect in the synthesis of the beta-globin chains, leading to alpha/beta imbalance, ineffective erythropoiesis, and chronic anemia. The spectrum of thalassemias is wide, with one end comprising thalassemia minor, which consists of a mild hypochromic microcytic anemia with no obvious clinical manifestations, while on the other end is thalassemia major, characterized by patients who present in their first years of life with profound anemia and regular transfusion requirements for survival. Along the spectrum lies thalassemia intermedia, a term developed to describe patients with manifestations that are neither mild enough nor severe enough to be classified in the spectrum s extremes. Over the past decade, our understanding of β-thalassemia intermedia has increased tremendously with regards to molecular information as well as pathophysiology. It is now clear that β-thalassemia intermedia has a clinical presentation as well as complications associated with the disease ...

The data indicate a change in codon 114 from CTG (Leu) to -GG that resulted in a frameshift and the presumed synthesis of an abnormal β chain that is 156 residues long with a completely different C-terminal amino acid sequence. The change in codon 114 gives a -GGGCCC- ...
Human beings have two beta and four alpha genes which are required to make protein chains. In beta thalassemia minor, the person has one abnormal beta gene which doesnt affect their health, while in beta thalassemia major, both the beta genes are abnormal. Beta thalassemia major is a fatal condition inherited by the offspring if both the parents have beta thalassemia minor. The patient of beta thalassemia major becomes dependant on blood transfusions, suffering from severe anemia, jaundice, spleen and liver enlargement and malfunctioning and bone problems.. ...
Anaemic adults with beta thalassemia who require regular red blood cell transfusions have a reason to celebrate now that the FDA has approved Reblozyl for their treatment.Today, there are some 550 adults with beta thalassemia in Cyprus requiring regular blood transfusions, while almost 35-40% of ann
Beta-thalassemia (β-thalassemia) is characterized by reduced synthesis of the haemoglobin subunit beta (haemoglobin beta chain) that results in microcytic hypochromic anaemia, an abnormal peripheral blood smear with nucleated red blood cells, and reduced amounts of haemoglobin A (HbA) on haemoglobin analysis. Individuals with thalassemia major have severe anaemia and hepatosplenomegaly; they usually come to medical attention within the first two years of life. Without treatment, affected children have severe failure to thrive and shortened life expectancy. Treatment with a regular transfusion program and chelation therapy, aimed at reducing transfusion iron overload, allows for normal growth and development and may improve the overall prognosis. Individuals with thalassemia intermedia present later and have milder anaemia that only rarely requires transfusion. [1] These individuals are at risk for iron overload secondary to increased intestinal absorption of iron as a result of ineffective ...
Epidemiological and clinical studies have indicated that the thalassaemias may confer protection against malaria. The study reported here investigated this protective effect in vitro, using a new approach which controls for the potential effect of red cell size and age on the virulence of the parasite. A Percoll density gradient method was used to separate alpha- and beta-thalassaemic trait, haemoglobin H and normal red blood cells (RBC) into fractions of different density. Correlations between RBC density, age and size in fractions of all genotypes were established using red cell creatine as an index of cell age. The development of Plasmodium falciparum over 3 erythrocytic cycles (144 h) in whole blood as well as fractionated samples was monitored by slide microscopy and flow cytometry. A significantly reduced rate of parasite invasion and growth was demonstrated in RBC from all thalassaemic genotypes tested. Poor reinvasion rates were noted in the second and third cycles. Increased duration of culture

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.. ...

To evaluate the association between fetal hemoglobin (HbF) levels and morbidity in β-thalassemia intermedia (TI), we analyzed data from 63 untransfused patients who had also never received HbF induction therapy. Patient records were reviewed for any history of 10 predefined morbidities. Laboratory measurements for markers of ineffective erythropoiesis were also obtained. The mean age of patients was 32.1 years, 47.6percent were males, and the median HbF level was 37.2percent. HbF levels correlated positively with total hemoglobin, yet negatively with growth differentiation factor-15 and non-transferrin-bound iron levels. Median HbF levels were significantly lower in patients with the majority of evaluated morbidities than in those without. There was a strong negative adjusted linear correlation between the HbF level and the total number of morbidities (R 2 = 0.825, P andlt; .001). The HbF threshold of 63.7percent had 95.5percent sensitivity and 100percent specificity for ensuring absence of ...
Manysavanh Loy Phothisane and Jay Ratttanavong are two Lao Americans who can be found at many community events and causes in Minnesota, volunteering their time and energy. Many around them may not know that theyre also affected with a blood disorder called thalassemia, which requires frequent hospitalizations and blood transfusions. Theyre hosting a Care Walk this Sunday, May 17th, 2015 to bring awareness of this health condition and to raise funds for more research. Below is a story shared by Manysavanh on living with thalassemia and why shes walking. Why Im walking on May 17th, 2015: As some of you know -or may have observed-I frequently receive blood transfusions because my body cannot produce normal hemoglobin, the protein in red blood cells that carries oxygen. Before I could barely form sentences, I was diagnosed with a serious form of Thalassemia, requiring me to depend on other peoples blood to survive (thank you and many blessings if youve ever donated blood).. Ive never shared ...
Thalassaemia major: also called Mediterranean anemia or Cooley anemia. It is caused by severe mutations in both alleles. No functional ß chains are produced, and thus no haemoglobin A can be assembled. This is he most severe form of ß-thalassemia: those with thalassaemia major need to have regular blood transfusions from infancy onwards in order to survive. Long term transfusions can lead to iron overload, so this patients also need iron chelating therapy ...

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 ...

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. ...
The progress of medicine can be viewed in steps determined by methodologic advances, as well as in the development of new ideas. Landmarks in methodology include early morphologic descriptions, and osmotic fragility tests used in diagnosing and screening for beta thalassemia, so effectively used by Silvestroni and Bianco in Italy from the 1940s onward. The discovery in 1957 by Kunkel and coworkers that hemoglobin A2 is elevated in most beta-thalassemia heterozygotes started a further phase of investigation, based on both clinical and population studies. Then came rapid developments in the analysis of the hemoglobin molecule, and the concept of alpha ...
Wheat grass juice reduces transfusion requirements in patients with thalassemia major: a pilot study.. Marwaha, R., Bansal, D., Kaur, S., Trehan A. 2004. Indian Ped. 41:716-720. Patients with thalassemia consuming wheat grass juice on a daily basis reduced on average their requirements for blood transfusion. Families raised and prepared the wheat grass at home and a comparison was made with the requirements of the patient in the preceding year. In nearly all patients the mean interval between visits increased and the blood transfused decreased during the wheat grass period. The mechanism involved is unknown.. ...
Coronavirus disease 2019 (COVID-19) has had and continues to have a significant medical, public health, social and economic impact on every society around the world. Some groups of chronic patients including thalassaemia and other haemoglobin disorders were considered from the beginning of the pandemic, as vulnerable and high risk ones with regards to a more severe clinical outcome of the infection with severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). This is because patients with thalassaemia can present with many and multiple co-morbidities including diabetes, heart, liver, endocrine and other conditions mainly secondary to iron overload and consequent to ineffective or suboptimal medical care and/or adherence to chelation treatment in particular. Transfusion dependent patients with β-thalassaemia have been greatly affected across the world, including in Iran, a country geographically situated in the so called thalassaemia belt. Iran with about 20,000 patients with ...

This integrative review aimed to synthesize factors related to family functioning in families living with children with thalassemia. CINAHL, PsycINFO, PubMed, and Scopus databases were searched for articles published from 2008 to 2019. Eleven studies involving 1,613 participants were included. The five factors identified comprised spirituality, illness belief, health literacy, social interaction and communication, and social and family support. The factor regarding social and family support was a significant factor resulting in a healthy level of family functioning. Family was the primary support system for children living with thalassemia and their whole family. Interestingly, illness belief, spirituality and magic as a source of family power, could lessen the burden and allow a stronger sense of control to transcend through difficult times. These five factors should be integrated in interventions designed to enhance family functioning. However, different cultures in each region should be ...
The type of beta thalassemia mutation found in heterozygous individuals is believed to influence hematological symptoms. Our data demonstrated that patients with the mild mutation (beta IVSI-nt 6) have a higher mean corpuscular hemoglobin (MCH) than those with the severe forms (beta(0)039 or beta IVSI-nt 1), and the hemoglobin A(2) levels were lower in beta(0) mutations than in the beta IVSI-nt 6 mutation. However, in contrast to previous studies, we were not able to indicate MCH as a clear discriminator between the beta(0) and beta(+) mutations ...
