What is sickle cell trait life expectancy? The life expectancy of people with sickle cell disease (SCA) is about twenty-two years shorter than that of people without SCA (sickle cell anemia). SCA is also associated with an increased risk for comorbid conditions, such as heart disease.
Sickle cell anemia causes a significantly lower overall life expectancy
However, while SCA causes a significantly lower overall life expectancy, it is a treatable disease, and nearly nine out of ten people with SCA will reach adulthood. In addition to its low overall life expectancy, SCA is also associated with serious health complications, including damage to the brain, heart, and other vital organs.
A large proportion of people with SCD have no apparent underlying chronic conditions. The majority of deaths, however, occur unexpectedly. Of these, 37 percent of patients experience sudden, painful death. Of those, twenty-five patients had concurrent or consecutive episodes of acute chest syndrome, while nine patients had a single episode.
Similarly, 15 patients died of acute stroke before they died, while 11 of them experienced hemorrhages. Furthermore, a small subset of patients die from infections unrelated to sickle cell disease. Some of these infections include Pneumococcal sepsis and Escherichia coli infections.
The median life expectancy for patients with SCD was a modest four years longer than for non-SCD patients. The median life expectancy for women with SCD was four years longer than for those with SCA. Males with SCA were about half as likely to live to age 40 than did females.
What causes sickle cell anemia?
The exact cause of sickle cell anemia is not known, but it involves a mutation in the hemoglobin gene. This causes sickle-shaped red blood cells, or RBCs, to fail to transport oxygen to other parts of the body.
This can lead to reduced oxygen delivery and increased risk of blood clots. About two million Americans have this disorder. It is most common in people of African, Mediterranean, and Caribbean ancestry.
The most common treatment for sickle cell anemia is bone marrow transplantation, but this procedure is not without risk. Side effects can include severe infections, seizures, and graft-versus-host disease. It is important to discuss the risks and benefits with a healthcare provider before considering this treatment.
One of the major problems associated with sickle cell disease is damage to the spleen. This organ is responsible for the removal of old red blood cells from the body. Sickled cells can clog the spleen, causing it to enlarge rapidly and cut off the flow of blood to organs and tissues. This leads to pain. In severe cases, the pain can last for days or weeks.
In some cases, sickle cell disease can run in families, as the disease can be inherited from both parents. However, the disease is more common in Africans, where one out of every four babies is born with sickle cell disease. In fact, up to 25 percent of Africans have the trait.
This disease is most common in Central and Western Africa, as well as the Middle East. The disease is characterized by the occlusion of capillaries by sickle-shaped erythrocytes. This occlusion of blood vessels causes acute and chronic damage to tissues and organs.
Sickle cell trait symptoms in adults
Fortunately, the majority of people with sickle cell trait have no symptoms or complications. However, if you suffer from this condition, it’s important to see your doctor to rule out any complications. The signs and symptoms of sickle cell disease may look like other medical conditions, so it’s important to get a proper diagnosis.
The most common symptoms of sickle cell disease are musculoskeletal pain, anemia, and pulmonary hypertension. People with sickle cell trait can also suffer from an increased risk of spleen damage. The spleen can become blocked with sickled cells, resulting in intense abdominal pain.
When sickled blood cells accumulate in the brain, they can cause a stroke. The blood in the brain will be unable to flow properly, leading to brain damage and a stroke. The affected person may experience sudden weakness of the arms or legs, speech difficulties, and even loss of consciousness. In some cases, the disease can lead to lung problems, including pneumonia. People with sickle cell disease may also have delayed growth.
A simple blood test will tell if you have sickle cell trait. If you do have the trait, you can take steps to stay healthy. If you pass on the trait to future generations, you risk increasing the risk of developing sickle cell disease.
How is sickle cell anemia inherited?
Sickle cell anemia is a hereditary blood disorder that can affect a child from either parent. Each person inherits two copies of a gene, called an allele. People who have one copy of the sickle cell trait will generally be asymptomatic, but having one or both alleles can result in the disease. Genetic testing for sickle cell anemia is an excellent way to determine whether you or your partner are at risk.
A person with the sickle cell trait will inherit the sickle haemoglobin gene from one parent and a normal hemoglobin gene from the other parent. This person is usually asymptomatic, but if their blood is under a lot of stress, they can become ill. A carrier can pass on the sickle cell gene to their children, but the child must also have both parents carrying the sickle cell gene.
People with sickle cell anemia may experience sudden weakness or pain on one side of the body. They may also experience pain in the upper left belly, or enlarged spleens. In children, the enlarged spleens are visible through the skin. Pain may also occur in the legs, especially in older adults.
Unlike normal blood cells, sickle cells have a short life span. They can survive for only 10 to 20 days. If they do not survive, they may be destroyed by the spleen, which filters the blood for infection-causing germs. As a result, the person with sickle cell anemia has a higher risk of getting an infection.
