Some adults with sickle cell anemia have high levels of fetal hemoglobin. Any reason for this?

Some adults with sickle cell anemia have high levels of fetal hemoglobin. Any reason for this?

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

How common is the inherited persistence of fetal hemoglobin?

Difficult to measure: This is difficult to measure because in most people with inherited persistence of fetal hemoglobin are entirely asymptomatic. However, population studies have shown that about 10% of the population has been seen to have some persistence of fetal hemoglobin but in varying levels (from 0.8% of cells containing the fetal hemoglobin up to about 10% fetal hemoglobin levels). ...Read more

I have elevated levels of fetal hemoglobin. What can cause this? I am not pregnant. Does it point to a disorder?

I have elevated levels of fetal hemoglobin. What can cause this? I am not pregnant. Does it point to a disorder?

Not necessarily: Elevated fetal hemoglobin may represent what is known as persistence of fetal hemoglobin. It would be helpful to know what the percentages of various hemoglobins are in your electrophoresis, This may be normal for YOU or it could represent a topic which needs investigation. Please speak to your doctor. Good luck! ...Read more

Can you die from low hemoglobin?

Can you die from low hemoglobin?

Yes absolutely: One can die due to a very low hemoglobin level- for instance due to massive bleeding- due to lack of oxygenation on the vitals organ causing cell deaths, organ failure and ultimately death. The incidence is low in the usa, as we do have much better access to medical center. In the other part of the world- those happen frequently unfortunately. ...Read more
