Presentation
Genetic studies of two families with sickle-cell-hemoglobin E disease have been presented. [bloodjournal.org]
Identification of this Hb variant is important because patients with doubly heterozygous HbE/β-thalassemia may present clinically as thalassemia major. [jlponline.org]
Numerous electrophoretic bands can occur when Hb G-Philadelphia is present. When Hb AA is present, there is usually 25 to 40 % Hb G-Phil and a faint band of G, in the carbonic anhydrase location. [sctpn.net]
In homozygous Hb E, no Hb A will be seen, whereas a small amount of Hb F (fetal Hb) may be present. Usually the amount of Hb F is In the present study we evaluated chromatograms of 70 patients with homozygous Hb E disorder. [degruyter.com]
Clinical Features One of the most striking features of HbE β thalassemia is its remarkable clinical heterogeneity The condition may present as a mild, asymptomatic anemia or a life-threatening disorder that may lead to death from anemia in the early [slideshare.net]

Workup
Medical Workup: The initial laboratory test to screen for sickle cell disease/trait is a Sickledex™; if positive then hemoglobin electrophoresis is required. Hb AS, with Hb S up to 45 % is acceptable for flying duties. [asams.org]
The tests that are ordered to search for haemoglobin variants are also used for thalassaemia workups. Searching for both is important because thalassaemia is sometimes inherited along with a haemoglobin variant. [labtestsonline.org.au]
Treatment
Occasionally blood transfusions Treatment varies depending on the symptoms and their severity. Some people do not need treatment. When treatment is needed for hemoglobin S-C disease, it is similar to that of sickle cell disease. [merckmanuals.com]
There are other treatments for specific complications. To stay as healthy as possible, make sure that you get regular medical care, live a healthy lifestyle, and avoid situations that may set off a pain crisis. [medlineplus.gov]

This allows treatment to begin as soon as possible. Early diagnosis and treatment can reduce the risk of problems. A blood test called hemoglobin electrophoresis may be done. It can tell if you are a carrier of sickle cell. [elcaminohospital.org]
Many states routinely screen newborns for sickle cell so that treatment can begin as soon as possible. Early diagnosis and treatment can reduce the risk of complications. [hopkinsmedicine.org]
Prognosis
However, in some cases the symptoms of beta-zero thalassemia are worse than those seen in homozygous sickle cell disease and is often associated with a poor prognosis. [hinapatelfoundation.org]
Pain episodes, end-organ damage, and prognosis may be similar or perhaps even worse for bone and retinal disease when compared to homozygous sickle anemia. [sctpn.net]
The prognosis of homozygous Hb C disease is excellent. An individual may inherit a Hb S gene from one parent and a Hb C gene from the other. The result of this double whammy is Hb SC disease. [web2.iadfw.net]

EPIDEMIOLOGY Hemoglobin E beta-thalassemia (Hb E thalassemia) accounts for approximately half of all the cases of severe thalassemia in the world population. Hb E thalassemia occurs widely throughout the eastern half of the Indian subcontinent, Bangladesh [slideshare.net]
Epidemiology Given the proposed survival advantage conferred by Hb C against malaria, it is not surprising that Hb C appears to have originated on the west coast of Africa. [emedicine.medscape.com]
Pathophysiology
Other pathophysiological mechanisms that contribute to the SCD phenotype are vaso-occlusion and activation of the immune system. SCD is characterized by a remarkable phenotypic complexity. [natureasia.com]
Pathophysiology The pathophysiology of HbE β thalassemia reflects both the reduced output of HbE together with the added globin-chain imbalance consequent on the coinheritance of β thalassemia Globally, the intermediate forms of beta-thalassaemia [slideshare.net]
Interaction between HbE and β-thalassemia alleles is the main determinant in pathophysiology. [4], [7], [8], [12] Thai investigations suggest that patients who coinherit a mild β-thalassemia allele with HbE may have disease on mild end of the spectrum [jlponline.org]
[…] chain, which produces a hemoglobin tetramer (alpha2/beta S2) that is poorly soluble when deoxygenated. 3 The polymerization of deoxy hemoglobin ( Hb ) S is essential to vasoocclusive phenomena. 3 However, polymerization alone does not account for the pathophysiology [asams.org]
Prevention
Early diagnosis and preventing further problems is critical in treating SCD. Treatment goals include preventing organ damage (including strokes), preventing infection, and treating symptoms. Treatment may include: Pain medicines. [elcaminohospital.org]
Regular and preventative health care is critical for people with sickle cell anemia. [medbroadcast.com]
