Official title
Treatment of Adult Patients With Hemoglobin SC Disease
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Sickle cell disease (SCD), specifically hemoglobin SC disease (HbSC), is a subtype of sickle cell disease with typically higher hemoglobin and milder or later disease complications. Sickle cell disease is a disorder in which red blood cells (RBCs) are abnormally shaped. This can result in painful episodes, serious infections, and damage to body organs. One medication used to treat sickle cell disease is hydroxyurea. Hydroxyurea therapy offers significant benefits for infants, children, and adolescents with sickle cell anemia. These include a reduction in the frequency of pain crises and acute chest syndrome (inflammation of the lungs). Hydroxyurea has been given to many HbSC patients but HbSC patients were not included in the large clinical trials used to test hydroxyurea in SCD, so less is known about how HbSC patients respond to hydroxyurea. The purpose of this research study is to see if hydroxyurea, a medication given to many patients with the most common type of sickle cell, those who are homozygous for the sickle mutation (HbSS), helps individuals who have HbSC. The investigators will see if it helps by giving a questionaire when the medication is started, and then every two months at a clinic visit. The questionaire, called the AdultsQLTM 3.0 Sickle Cell Disease Module, measures quality of life. The investigators will also see how hydroxyurea changes laboratory test numbers, and blood thickness.
