Can You Develop Sickle Cell Anemia As An Adult
Inherited: Sickle cell anemia is hereditary. But it comes in several varieties depending on what was inherited from parents. S-s is severe & usually diagnosed in infancy. S-a is carrier state & may go undetected into adulthood. Many variants are possible. This refers to how hemoglobin proteins are manufactured by red cells programmed by genes. See: http://ghr. Nlm.

Epigenetics and drug: We know that sickle cell patients that have increased Hemoglobin F typically have less sickle cell complications. This is the basis for using Hydroxyurea in sickle cell patients. Some individuals have elevated Hemoglobin F levels due to differences in the genetic region of the beta and gamma globin genes that prevent the normal shutting-off of the gamma globin gene. This leads to increased HGB f. ...Read more
Might it happen that a caucasian develop sickle cell anemia after a blood transfusion from an afrimight it happen that amerimight it happen that donor?
More info needed: Patients with sickle cell anemia have greater tendency for severe anemia and infection. Usually children have more difficulties. Sometimes frequent transfusion is needed to assist in crises, or to suppress sickle hemoglobin and decrease sickling issues which can be very painful. Hydroxyurea is used to help symptoms and to increase fetal hemoglobin, vaccinations, and antibiotics help. See MD. ...Read more
Who will have it bad: The trend currently is trying to find out why some people have very little problems and others can be so troubled by this disease. In some, the disease will cause strokes, lung problems, leg ulcers etc. If we knew early on who would have it bad, maybe treatments could be given earlier to prevent these problems. But not everyone has it bad, so it is hard to know. ...Read more
See below: Sickle cell anemia occurs when 2 abnormal hemoglobin genes are present and a person's body produces sickle cell hemoglobin exclusively. 1 sickle cell gene and a normal gene produce sickle trait, which has no symptoms. Other abnormal hemoglobin genes can combine with a sickle cell gene and produce other types of anemia. There are several other genetic hemoglobin abnormalities. ...Read more
Anemia, pain, crises:
The most frequent presenting signs/symptoms of sickle cell include anemia and typical sickle cell crises which include pain crises (severe pain in arms, legs, shoulders, back), acute chest crisis (shortness of breath, cough, fever, lung infiltrate), dactylitis (pain toes/fingers usually as a toddler) and others.
Most patients that have sickle cell trait are completely asymptomatic. ...Read more
Many.: Basically, sickle cell disease causes disturbance of the blood vessels, typically smaller vessels. Over time, this can cause many problems. Painful episodes, eye problems, lung problems (similar to pneumonia), strokes, decreased spleen function (which can cause severe infections), kidney problems, and o ther problems. Sickle cell disease is not the same in all people. Some have milder symptoms. ...Read more
Genetic: With ss disease a genetic mutation changes the gene sequencing needed for normal hemoglobin production. The alteration changes the way the hemoglobin handles the oxygen molecule as it carries it in the blood. The blood cell then becomes distorted in the small capillaries and the spleen. The cell breaks down rapidly and or remains trapped. Anemia is a chronic problem. ...Read more
