In humans, using hydroxyurea to stimulate the production of HbF has been known to temporarily alleviate sickle cell disease symptoms. The researchers demonstrated that this gene therapy method is a more permanent way to increase therapeutic HbF production.
The Food and Drug Administration on Friday approved a powerful treatment for sickle cell disease, a devastating illness that affects more than 100,000 Americans, the majority of whom are...
The FDA is reviewing a new drug for sickle cell disease that uses CRISPR to edit DNA. Black patients with the disease are excited and hopeful about the treatment.
Sickle cell retinopathy can be defined as retinal changes due to blood vessel damage in the eye of a person with a background of sickle cell disease. It can likely progress to loss of vision in late stages due to vitreous hemorrhage or retinal detachment . [1]
Sickle cell trait describes a condition in which a person has one abnormal allele of the hemoglobin beta gene (is heterozygous), but does not display the severe symptoms of sickle cell disease that occur in a person who has two copies of that allele (is homozygous).
The FDA is reviewing a drug that could cure sickle cell anemia. Right now bone marrow or stem cell transplants are the only FDA-approved cures.
Cause. Sickle cell-Hb Lepore Boston syndrome is a type of sickle cell disease (HbS) that differs from homozygous sickle cell disease where both parents carry sickle hemoglobin. In this variant one parent has the sickle cell hemoglobin the second parent has Hb Lepore Boston, the only one of the three variants described in association with HbS.
Sickle cell nephropathy is a type of nephropathy associated with sickle cell disease which causes kidney complications as a result of sickling of red blood cells in the small blood vessels.
Symptoms: acute, severe pain: Diagnostic method: There is no test to confirm a vaso-occlusive crisis, but tests can be done to rule out other causes. Patients with vaso-occlusive crisis present with pain (mild to severe) and a history of sickle cell anemia. Differential diagnosis: Neuropathic pain, hyperalgesia, osteomyelitis
The acute chest syndrome is a vaso-occlusive crisis of the pulmonary vasculature commonly seen in people with sickle cell anemia. This condition commonly manifests with a new opacification of the lung(s) on a chest x-ray.
