Sickle cell is what type of anemia




















Frequent blood transfusions can lead to liver damage from iron overload. Pregnancy problems. Pregnancy can increase the risk for high blood pressure and blood clots in women who have sickle cell disease. The condition also increases the risk of miscarriage, premature birth, and low birth weight babies.

Learn more about pregnancy and sickle cell disease. Priapism is an unwanted, sometimes prolonged, painful erection. This happens when blood flow out of the erect penis is blocked by sickled cells.

Over time, priapism can cause permanent damage to the penis and lead to impotence. Priapism that lasts for more than 4 hours is a medical emergency. Severe anemia. People who have sickle cell disease usually have mild to moderate anemia. At times, however, they can have severe anemia, which is life-threatening.

Stroke or silent brain injury. Silent brain injury, also called silent stroke, is damage to the brain without showing outward signs of stroke. This injury is common and can be detected on magnetic resonance imaging MRI scans. Silent brain injury can lead to difficulty in learning, making decisions, or holding down a job.

Severe anemia complications People who have sickle cell disease also usually have mild to moderate anemia. Severe anemia in a newborn or child who has sickle cell disease may be a result of: Aplastic crisis. Aplastic crisis is usually caused by a parvovirus B19 infection, also called fifth disease or slapped cheek syndrome. Parvovirus B19 is a very common infection, but in sickle cell disease, it can cause the bone marrow to stop producing new red cells for a while, leading to severe anemia.

Splenic sequestration crisis. Your spleen filters your blood and destroys old blood cells. In people who have sickle cell disease, red blood cells may get trapped in the spleen, making it quickly grow larger than normal. With red blood cells trapped in the spleen, fewer are available to circulate in the blood, and this can lead to severe anemia. A large spleen may also cause pain in the left side of the belly. Diagnosis - Sickle Cell Disease. Newborn screening When a child has sickle cell disease, early diagnosis is important to better prevent complications.

Prenatal screening Doctors can also diagnose sickle cell disease before a baby is born. Treatment - Sickle Cell Disease.

Medicines Voxelotor The U. Crizanlizumab-tmca In , the FDA also approved a new medicine to reduce the number of pain crises experienced by adults and children 16 years and older who have sickle cell disease.

Penicillin In children who have sickle cell disease, taking penicillin two times a day has been shown to reduce the chance of having a severe infection caused by the pneumococcus bacteria. Hydroxyurea Hydroxyurea is an oral medicine that has been shown to reduce or prevent several sickle cell disease complications.

Use in adults. It also improved anemia and decreased the need for transfusions and hospital admissions. Use in children.

There is no information about how safe or effective hydroxyurea is in children under 9 months of age Pregnant women should not use hydroxyurea. Transfusions Your doctor may recommend transfusion to treat and prevent certain sickle cell disease complications.

These transfusions may include: Acute transfusion to treat complications that cause severe anemia. Doctors may also use transfusions when a patient has an acute stroke, in many cases of acute chest crises, and in multi-organ failure.

A patient who has sickle cell disease usually receives blood transfusions before surgery, to prevent complications. Red blood cell transfusions to increase the number of red blood cells and provide normal red blood cells that are more flexible than red blood cells with sickle hemoglobin. Regular or ongoing blood transfusions for people who have had an acute stroke, to reduce the chances of having another stroke.

Doctors also recommend blood transfusions for children who have abnormal transcranial Doppler TCD ultrasound results, because transfusions can reduce the chance of having a first stroke. Some doctors use this approach to treat complications that do not improve with hydroxyurea. Doctors may also use transfusions in people who have too many side effects from hydroxyurea. Possible complications include alloimmunization , which can make it hard to find a matching unit of blood for a future transfusion; infection; and iron overload.

Blood and bone marrow transplant A blood and bone marrow transplant is currently the only cure for sickle cell disease, but it is not for everyone. Potential genetic therapy treatments for sickle cell disease Researchers at the NHLBI are exploring ways genetic therapies may help develop new treatments or find a cure for sickle cell disease.

Living With - Sickle Cell Disease. Receive routine follow-up care See your doctor regularly. Most people who have sickle cell disease should see their doctor every 3 to 12 months, depending on their age. Get regular vaccines, including an influenza or flu shot every year. Your doctor may also recommend a second pneumococcus PPSV23 , in addition to the pneumococcus one PCV13 that all children get as part of their regular immunizations.

This second vaccine is given after 24 months of age and again 5 years later. Adults who have sickle cell disease and have not received any pneumococcal vaccine should get a dose of the PCV13 vaccine. They should later receive the PPSV23 if they have not already received it or if it has been more than 5 years since they did. Follow these guidelines even if you or your child is still taking penicillin.

Learn how to manage pain When an acute crisis is just starting, drink lots of fluids and take a nonsteroidal anti-inflammatory NSAID pain medicine, such as ibuprofen. If you have kidney problems, acetaminophen is often preferred. You may be able to return home once your pain is under better control. You may need to be admitted to the hospital to fully control an acute pain crisis. Adopt a healthy lifestyle Get regular physical activity. You may tire easily, so be careful to pace yourself and avoid very strenuous activities.

Choose heart-healthy foods , including limiting alcohol. Drink extra water to avoid dehydration. Quit smoking. Although these resources focus on heart health, they include basic information about how to quit smoking. Extreme heat or cold, as well as abrupt changes in temperature, are often triggers. When going swimming, ease into the water rather than jumping right in. Do not travel in an aircraft cabin that is unpressurized. If you experience priapism prolonged, painful erection , you may be able to relieve your symptoms by doing light exercise, emptying your bladder by urinating, drinking more fluids, and taking medicine recommended by your doctor.

If your child attends daycare, preschool, or school, speak to his or her teacher about the disease. Teachers need to know what to watch for and how to accommodate your child.

They should try to feel for the spleen daily and more often when the child is ill. If the spleen feels larger than usual, they should call the care provider. Seek help if you have feelings of depression or anxiety. Supportive counseling and, sometimes, antidepressant medicines may help. Know when to seek emergency medical care Sickle cell disease can lead to serious and life-threatening health problems. Symptoms of severe anemia, including extreme tiredness fatigue , shortness of breath, dizziness, or irregular heartbeat.

Splenic sequestration crisis or an aplastic crisis can cause severe anemia symptoms. These conditions can be life-threatening.

All children and adults who have sickle cell disease and a fever of more than Some people will need to be hospitalized. Symptoms of acute chest syndrome, including chest pain, coughing, fever, and shortness of breath. You will need to be admitted to the hospital, where you may receive antibiotics, oxygen therapy, or a blood transfusion. Signs and symptoms of a stroke, such as sudden weakness, numbness on one side of the body, confusion, or trouble speaking, seeing, or walking.

If you experience priapism that lasts for 4 hours or more, go to the hospital to see a hematologist and urologist. Pregnancy and sickle cell disease Pregnant women who have sickle cell disease are at greater risk for problems. Research for Your Health. Improving health with current research. The goal is to have these genetic therapies ready to safely use in clinical research within five to 10 years. The Initiative is patient-focused, and it will bring together researchers, private sector researchers, patients, providers, advocacy groups, and others as it supports research, education, and community engagement activities.

A Legacy of Research Excellence. We have supported research on sickle cell disease since our founding in With each decade since, the NHLBI has kept a sustained focus on advancing the understanding of sickle cell disease and improving clinical care. The NHLBI is committed to building on its legacy of research excellence to find new treatments, cures, and personalized care for the approximately , Americans and over 20 million people worldwide who have sickle cell disease.

Researchers found that African Americans who have sickle cell trait were not at an increased risk of stroke. Each year, we bring together researchers and health professionals to discuss clinical trials, research, and clinical care for sickle cell disease.

Explore resources from the annual meeting. More than 75 percent of newborns who have sickle cell disease are born in sub-Saharan Africa. By funding the Sickle Cell Disease in Sub-Saharan Africa Collaborative Consortium and associated Data Coordinating Center, we are building the regional capabilities to research sickle cell disease and monitor patients in Africa. We also support development of an inexpensive and simple screening test for use in sub-Saharan Africa, an area where medical resources and access to newborn screening tests are limited.

The test can lead to earlier diagnoses and treatment for children who have sickle cell disease in these areas. Advancing research on sickle cell treatment from the laboratory to clinical trials. NHLBI funding supports research on a new medicine for sickle cell disease to increase healthy fetal hemoglobin that can replace the sickle cell hemoglobin.

Read more. This graph shows the average life expectancy for people with sickle cell disease from to Starting in , life expectancy begins making a sharp increase, rising to around 14 years in and surging to more than 40 years by This longer lifespan for patients with sickle cell disease is in part due to clinical use of penicillin, hydroxyurea, and blood transfusions that were proven to be safe and effective interventions in landmark NHLBI-funded trials.

Read less. Advancing research for improved health. We perform research. Blood transfusions may be necessary if a person has severe anemia, an enlarged spleen, infections, or other complications. A stem cell transplant using cells from a matched, healthy donor can cure sickle cell disease, but it can be risky. Also, the stem cells must be closely matched. People with sickle cell disease or sickle cell trait cannot give blood, but healthcare professionals encourage anyone who can donate to do so.

This may help a person with these conditions. Many people have a healthy pregnancy with sickle cell disease. However, there may be a higher chance of:.

People with sickle cell disease or sickle cell trait may wish to speak to a genetic counselor if they plan to have children. Many people with sickle cell disease can live a full and active life, especially if they take action to reduce the effects of the condition. Lifestyle measures that may help include :. Health insurance will cover the treatment of sickle cell disease. If a person does not have insurance, they can purchase it under the Affordable Care Act or apply for Medicaid. Scientists are currently looking for a cure that will help all people with sickle cell disease.

They hope to establish a next-generation therapy within 5—10 years. The National Heart, Lung, and Blood Institute provide a list of clinical trials that vary by age groups and other factors.

A new drug for sickle cell disease appears to be effective in a mouse model of the condition. Now, a new study concludes that the drug is safe for…. Sickle cell anemia is congenital, meaning it is present at birth, and symptoms vary between individuals depending on severity. Scientists believe it…. Sickle cell anemia is a genetic condition that causes red blood cells to malfunction. This is commonly called sickle cell anemia and is usually the most severe form of the disease.

Hemoglobin is a protein that allows red blood cells to carry oxygen to all parts of the body. This is usually a milder form of SCD. Did you know SCD affects people from many parts of the world?

The severity of these rarer types of SCD varies. This is called sickle cell trait SCT. People with SCT usually do not have any of the signs of the disease and live a normal life, but they can pass the trait on to their children. Additionally, there are a few, uncommon health problems that may potentially be related to sickle cell trait. SCD is a genetic condition that is present at birth. It is inherited when a child receives two sickle cell genes—one from each parent.

Some adolescents and adults with sickle cell anemia also have chronic pain, which can result from bone and joint damage, ulcers, and other causes. Sickle cell anemia is usually diagnosed in infancy through newborn screening programs.

If you or your child develops any of the following problems, see your doctor right away or seek emergency medical care:. Sickle cell anemia is caused by a mutation in the gene that tells your body to make the iron-rich compound that makes blood red and enables red blood cells to carry oxygen from your lungs throughout your body hemoglobin. In sickle cell anemia, the abnormal hemoglobin causes red blood cells to become rigid, sticky and misshapen.

If only one parent passes the sickle cell gene to the child, that child will have the sickle cell trait. With one normal hemoglobin gene and one defective form of the gene, people with the sickle cell trait make both normal hemoglobin and sickle cell hemoglobin. Their blood might contain some sickle cells, but they generally don't have symptoms. They're carriers of the disease, however, which means they can pass the gene to their children.

For a baby to be born with sickle cell anemia, both parents must carry a sickle cell gene. In the United States, sickle cell anemia most commonly affects black people. If you carry the sickle cell trait, seeing a genetic counselor before trying to conceive can help you understand your risk of having a child with sickle cell anemia.
