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).
Problems in sickle cell disease typically begin around 5 to 6 months of age. [1] A number of health problems may develop, such as attacks of pain (known as a sickle cell crisis) in joints, anemia, swelling in the hands and feet, bacterial infections, dizziness [9] and stroke. [1]
Signs and symptoms. Patients with sickle cell-beta thalassemia may present with painful crises similar to patients with sickle cell disease [citation needed] Cause. Sickle cell-beta thalassemia is caused by inheritance of a sickle cell allele from one parent and a beta thalassemia allele from the other. Mutations
Beta thalassemia trait (also known as beta thalassemia minor) involves heterozygous inheritance of a beta-thalassemia mutation and patients usually have borderline microcytic, hypochromic anemia and they are usually asymptomatic or have mild symptoms.
Signs and Symptoms. Microalbuminuria is an early sign of SCN that has a 30-60% of developing in those with sickle cell disease (SCD). Hematuria can appear in a range of severities from painless and minute to excessive and painful.
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
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 Anemia, a Molecular Disease. " Sickle Cell Anemia, a Molecular Disease " is a 1949 scientific paper by Linus Pauling, Harvey A. Itano, Seymour J. Singer and Ibert C. Wells that established sickle-cell anemia as a genetic disease in which affected individuals have a different form of the metalloprotein hemoglobin in their blood.
Signs and symptoms. The crisis is a common complication in sickle-cell patients and can be associated with one or more symptoms including fever, cough, excruciating pain, sputum production, shortness of breath, or low oxygen levels. [2]
Sickle cell anemia symptoms usually appear around the age of six months. They can change over time and differ from person to person. A few indications and symptoms include anemia, sporadic episodes of excruciating pain, hand and foot edema, recurrent infections, delayed puberty or growth, and visual issues.
