What is Hypertransfusion in thalassemia?
Hypertransfusion therapy is based on the reduction of ineffective erythropoiesis and improvement of the anaemia. To prevent iron overload, continuous chelation therapy was performed with desferrioxamine (DFO). The efficacy of such management in 10 thalassaemia maior patients followed-up for 11 years has been evaluated.
Why is there hypogonadism in thalassemia?
Hypogonadism is the most frequently reported endocrine complication, affecting 70–80% of thalassemia major patients. Hypogonadism is likely to be caused by iron deposits in the gonads, pituitary gland or both.
Does thalassemia cause hemolysis?
The thalassemias (named from the Greek word for sea, thalassa1) are a group of inherited autosomal recessive hematologic disorders2 that cause hemolytic anemia because of the decreased or absent synthesis of a globin chain. Imbalances of globin chains cause hemolysis and impair erythropoiesis.
Why is there splenomegaly in thalassemia?
An enlarged spleen in individuals with beta thalassemia may occur due to increased destruction of red blood cells, the formation of blood cells outside of the bone marrow (extramedullary hematopoiesis), repeated blood transfusions, or iron overload.
What is Hypertransfusion regimen?
Hypertransfusion refers to a chronic blood transfusion regimen with therapeutic intention of reducing sickle haemoglobin levels over a long period of time [17. N.
Does thalassemia affect testosterone?
An emerging endocrine disorder in young adult TD β-thal subjects is acquired hypogonadotropic hypogonadism (AHH) (21). AHH is a disorder caused by the inability of the testes to produce physiologic levels of testosterone and normal numbers of spermatozoa as a result of a disruption of the H-P-G axis (18).
Can thalassemia cause erectile dysfunction?
In patients with thalassemia major or transfusion-dependent thalassemia, ED is a possible complication predominantly due to iron overload as a result of recurrent blood transfusion leading to hypogonadism.
Why is ferritin high in thalassemia?
This means that high serum ferritin in minor thalassemia and nontransfused hemoglobinopathy may be due to long-term gastrointestinal absorption instead of iron supplementation in the short term. Hematological indices including Mentzer Index, Srivastava Index and new formula by Bordbar et al.
When is splenectomy indicated in thalassemia?
Physicians often use splenectomy to decrease transfusion requirements in patients with thalassemia major. (Patients with thalassemia minor only rarely require splenectomy.) Splenectomy is recommended when the calculated annual transfusion requirement is greater than 200-220 mL RBCs/kg/y with a hematocrit value of 70%.
Why do we do splenectomy in thalassemia?
Many patients with thalassaemia require splenectomy. The main therapeutic rationale for splenectomy in transfusion-dependent patients with β-thalassaemia major (TM) is to decrease blood consumption and transfusion requirement with the ultimate goal of reducing iron overload (Rachmilewitz 2011, Cohen 2008).
Is HbE and thalassemia same?
Hemoglobin E (HbE) is an extremely common structural hemoglobin variant that occurs at high frequencies throughout many Asian countries. It is a β-hemoglobin variant, which is produced at a slightly reduced rate and hence has the phenotype of a mild form of β thalassemia.
What are the symptoms of hemoglobin E?
Most people have no symptoms. Those with hemoglobin E trait plus a second abnormal hemoglobin gene (as described above), may have thalassemia, or anemia-like symptoms….What are the symptoms of hemoglobin E trait?
- Severe tiredness (fatigue)
- Growth failure.
- Shortness of breath.
- Jaundice, or a yellowing of the skin.
Can thalassemia affect fertility?
Although spontaneous fertility can occur in well-transfused and well-chelated patients with thalassemia, infertility mainly due to HH still remains one of the most common morbidities and obstacles for having children [9,10,11,12,13,14,15]. In our cohort, male and female fertility rates were 50%.
Does thalassemia affect male fertility?
Some researchers have found that more than half of men with thalassemia patients treated with blood transfusion and chelation are affected by abnormal sperm quality and oligospermia due to iron overload [41].
Why is RBC count increased in thalassemia?
In α-thalassemia, reduced production of α-globin results in tetramers of β-globin known as hemoglobin H (HbH) that can precipitate within mature red blood cells. This in turn results in an anemia from hemolysis and destruction of these red blood cells, as well as some ineffective production of such red blood cells.
Is RDW high or low in thalassemia?
Until now, many studies have shown a high efficacy of RDW in distinguishing IDA from the thalassemia trait, but this has not been the same for thalassemia disease. Our study used RDW for differentiating between IDA and NTDT in adults with moderate to severe microcytic anemia, according to the WHO classification.
Does thalassemia have high RDW?
The RDW is normal in patients with thalassemia and anemia of chronic disease but high in those with iron deficiency. The MCV is decreased in iron-deficiency anemia and in thalassemia minor and normal or decreased in chronic disease.
What are the signs and symptoms of thalassemia?
Thalassemia signs and symptoms may include: Fatigue. Weakness. Pale or yellowish skin. Facial bone deformities. Slow growth. Abdominal swelling.
Is there an endocrinopathy in thalassaemia major?
Endocrinopathy in thalassaemia major. N McIntosh Copyright and License informationDisclaimer Copyright notice This article has been cited byother articles in PMC. Abstract Pituitary, adrenal, and pancreatic functions were investigated in 9 patients with thalassaemia major. 9 a.m. plasma ACTH values were 148-480 pg/ml (normal range 15-70 pg/ml).
What happens if you get too much iron with thalassemia?
Iron overload. People with thalassemia can get too much iron in their bodies, either from the disease or from frequent blood transfusions. Too much iron can result in damage to your heart, liver and endocrine system, which includes hormone-producing glands that regulate processes throughout your body.
How does the severity of thalassemia depend on my Genes?
In alpha-thalassemia, the severity of thalassemia you have depends on the number of gene mutations you inherit from your parents. The more mutated genes, the more severe your thalassemia.
