Thalassemia ppt

Thalassemia 1. INTRODUCTION Thalassemia is an inherited autosomal recessive blood disorder. which results in excessive destruction of red blood cells and further leads to anemia. It is caused by variant or missing genes that affect how the body make haemoglobin. People with thalassemia make less haemoglobin and fewer circulating red blood cells than normal ,result in mild or severe anemia Thalassemia: The Symptoms & Treatments - Thalassemias are a heterogeneous group of genetically transmitted disorders characterized by anaemia, jaundice, and increased size of liver and spleen. Anaemia, the hallmark symptom is due to premature destruction of red blood cells in the bone marrow for the defective haemoglobin they synthesize and possess, a direct impact of the faulty genes DEFINITION • Thalassemia is an autosomal -recessive genetic disorder that results in adequate normal Hb production. Whereas IDA affects heme synthesis of globin. • Thalassemia is a group of diseases that have an autosomal recessive genetic basis involving inadequate production of normal Hb. 5

Thalassemia (quantitative) • A quantitative decrease in the production of alpha or beta globin chain - Large deletions, point mutations, small insertion/deletion that leads to decreased transcription or an unstable transcript • Beta thalassemia results from mutations in beta gene(s) - Pathogenesis a result of the free alpha subunit
  3. Thalassemia is an inherited (i.e., passed from parents to children through genes) blood disorder caused when the body doesn't make enough of a protein called hemoglobin, an important part of red blood cells. When there isn't enough hemoglobin, the body's red blood cells don't function properly and they last shorter periods of time, so there are fewer healthy red blood cells traveling.

Thalassemia is a blood disorder that is caused by DNA mutations in cells that are responsible for producing haemoglobin. This leads to a reduction in the number and ability of the red blood cells to carry oxygen throughout the body and can cause sufferers to feel symptoms such as fatigue People with thalassemia minor or trait usually do not need blood transfusions because they either do not have anemia or have only a mild anemia. Many times people with thalassemia are prescribed a supplemental B vitamin, known as folic acid, to help treat anemia. Folic acid can help red blood cells develop Thalassemia is often accompanied by the destruction of a large number of red blood cells and the task of removing these cells causes the spleen to enlarge. Splenomegaly can make anemia worse, and it can reduce the life of transfused red blood cells. Severe enlargement of the spleen may necessitate its removal

Thalassemia cannot be prevented since it is a genetically inherited disorder. However, these disorders can be detected during prenatal tests before birth. Also, genetic counselling helps to detect whether people have altered or missing haemoglobin genes that cause thalassemia Thalassemia intermedia may result from a variety of molecular processes, but its milder clinical presentation is usually due to a less marked imbalance of the α:β globin chain ratio. The dysfunction of several organ systems has been documented in patients with β-thalassemia.1 However, few studies have evaluated th Thalassemia is an inherited blood disorder that requires lifelong adherence to a complicated and burdensome medical regimen which could potentially impact emotional functioning of patients β-Thalassemia is caused by β-globin gene mutations that inhibit production of the corresponding protein. Consequently, free α-globin accumulates, which is toxic to red blood cells and their precursors. Normally, there are 2 β-globin genes. Loss of 1 β-globin gene usually causes β -thalassemia trait, which is asymptomatic, although red.

Several clinical forms of α-thalassaemia and β-thalassaemia, including the co-inheritance of β-thalassaemia with haemoglobin E resulting in haemoglobin E/β-thalassaemia, have been described. The disease hallmarks include imbalance in the α/β-globin chain.

The hallmark of the disease is the α-globin or β-globin chain imbalance that leads to ineffective erythropoiesis with associated medullary expansion and bone defects, appearance of extramedullary haemopoietic pseudotumours, chronic haemolytic anaemia with associated growth implications and gall stones, a hypercoagulable state leading to.

  3. Thalassaemia is the name for a group of inherited conditions that affect a substance in the blood called haemoglobin. People with thalassaemia produce either no or too little haemoglobin, which is used by red blood cells to carry oxygen around the body. This can make them very anaemic (tired, short of breath and pale)
  4. Introduction. Thalassemia syndrome is the most common inherited disorder worldwide. The prevalence of thalassemia carriers is high among the populations in the Mediterranean, Eastern European and the Southeast Asian regions.[] The severity of the disease depends on the degree of imbalance in the quantity of the globin chains. β-thalassemia is an example of this syndrome, caused by a defective.
  5. Thalassemia. Thalassemia is a blood disorder passed down through families (inherited) in which the body makes an abnormal form or inadequate amount of hemoglobin. Hemoglobin is the protein in red blood cells that carries oxygen. The disorder results in large numbers of red blood cells being destroyed, which leads to anemia
  6. Introduction. Thalassemia (thal) is an autosomal recessive hereditary chronic hemolytic anemia due to a partial or complete deficiency in the synthesis of α-globin chains (α-thal) or β-globin chains (β-thal) which compose the major adult hemoglobin (HbA), a tetramer of α 2 β 2.It is caused by one or more of several hundred mutations in the corresponding genes
  7. 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. Workup in alpha thalassemia relies primarily on laboratory evaluation, hemoglobin electrophoresis, and.

Abstract. Chronic hemolytic anemia has increasingly been identified as an important risk factor for the development of pulmonary hypertension (PH). Within the thalassemia syndromes, there are multiple mechanisms, both distinct and overlapping, by which PH develops and that differ among β-thalassemia major or intermedia patients Thalassemia. Thalassemia is a hereditary cause of microcytic, hypochromic anemia. It is a deficiency in either the alpha (α) or beta (β) globin chain resulting in hemoglobinopathy. The presentation of thalassemia depends on the number of defective chains present

(Thalassemia genes produce normal hemoglobin, but in variably reduced amounts). If the gene produces no normal hemoglobin, b 0-thalassemia, the condition is virtually identical to sickle cell disease. Some patients have a gene that produces a small amount of normal hemoglobin, called b +-thalassemia 9 BAB II TINJAUAN PUSTAKA 2.1 Thalassemia Thalassemia merupakan kelainan genetik dimana terjadi mutasi di dalam atau di dekat gen globin yang ditandai dengan tidak ada atau berkurangnya sintesis rantai globin.18,19,20 Kecepatan sintesis (rate of synthesis) pada thalassemia atau kemampuan produksi rantai globin mengalami perubahan kuantitatif Alpha thalassemia occurs when some or all of the 4 genes that make hemoglobin (the alpha-globin genes) are missing or damaged. There are 4 types of alpha thalassemia: Alpha thalassemia silent carrier. One gene is missing or damaged, and the other 3 are normal. Blood tests are usually normal. Your red blood cells may be smaller than normal Tests used to diagnose thalassemia in fetuses include: Chorionic villus sampling. Usually done around the 11th week of pregnancy, this test involves removing a tiny piece of the placenta for evaluation. Amniocentesis. Usually done around the 16th week of pregnancy, this test involves examining a sample of the fluid that surrounds the fetus ing b-thalassemia are point mutations affect-ing a single nucleotide, or a small number of nucleotides, in the b-globin gene. Rare deletion forms of b-thalassemia have also been de-scribed. One of these deletions iscaused by un-equal crossing over between the linked and partially homologous d- and b-globin genes

Thalassemia is a group of inherited blood disorders caused by defects in one or more genes responsible for producing the globin chains in hemoglobin. The clinical syndromes are the result of two problems. First, insufficient synthesis of either α- or β-globin leads to inadequate production of the predominant adult hemoglobin A (α 2 β 2) and. Thalassemia is a congenital hemolytic disorder caused by a partial or complete deficiency of α- or β-globin chain synthesis. Homozygous carriers of β-globin gene defects suffer from severe anemia and other serious complications from early childhood. The disease is treated by chronic blood transfusion. However, this can cause severe iron. The α-globin genes are duplicated and embedded into two highly homologous 4 kb units, divided into X-, Y- and Z- homology boxes.The most common rearrangement in this region is a single α-globin gene deletion, caused by an unequal homologous recombination during meiosis between the mis-paired X and Z-boxes giving rise to the - α 4.2 and - α 3.7 deletion respectively (Fig. 3a and b) , 3.

thalassemia results in the clinically silent carrier state. HbE/beta-thalassemia and HbC/beta-thalassemia exhibit a great range in terms of diversity of phenotypes and spectrum of severity. Beta-thalassemia major Clinical presentation of thalassemia major occurs between 6 and 24 months. Affected infants fail to thrive and become progressively pale Thalassemia intermedia (TI), also known as nontransfusion dependent thalassemia (NTDT), is a type of thalassemia where affected patients do not require lifelong regular transfusions for survival but may require occasional or even frequent transfusions in certain clinical settings and for defined periods of time. NTDT encompasses three distinct clinical forms: <i>β</i>-thalassemia.
