Sickle Cell Disease in Children

Sickle Cell Disease in Children

Generally, red cell (RBCs) are shaped like round discs. People who have sickle cell disease, though, have RBCs that are shaped like sickles, or crescent moons. This defect can cause painful episodes, serious infections, chronic anemia, and damage to body organs.

These complications can vary from person to person depending on which type of sickle cell disease each has. Some people are fairly healthy and others are hospitalized often.

But thanks to improvements in early medical diagnosis and treatment, most kids born with this acquired disorder mature to live active, healthy, and productive lives.

Early recognition of babies with sickle cell disease (SCD) by newborn screening, now universal in all 50 states in the US, has improved survival, generally by preventing frustrating sepsis with the early use of prophylactic penicillin. Routine transcranial Doppler screening with the institution of chronic transfusion reduces the risk of stroke from 10% to 1% in paediatric SCD patients. Hydroxyurea decreases the number and frequency of painful crises, acute chest syndromes and number of blood transfusions in children with SCD. Genetic research continues to be driven towards the prevention and ultimate treatment of SCD before the adult years. This evaluation concentrates on clinical symptoms and therapeutic methods for paediatric SCD in addition to the developing topic of gene-focused avoidance and therapy.

A Closer Take a look at Sickle Cell Disease

The different types of sickle cell disease are identified by the genes inherited from the person’s parents.

Someone who acquires a sickle cell gene from each parent has hemoglobin SS disease, also called sickle cell anemia.

An individual can likewise inherit a sickle cell gene from one parent and a different kind of irregular gene from the other and end up with a different form of sickle cell disease, such as hemoglobin SC disease or hemoglobin S beta thalassemia.

Somebody who inherits only one sickle cell gene and a normal gene from the other parent will have the sickle cell quality, but not the disease. A blood test can determine whether somebody has a kind of sickle cell disease or carries the sickle cell characteristic.

People with sickle cell quality do not have sickle cell disease and normally do not show signs of the disorder, but they can pass the gene for the disease to their children. Many people have no idea they have sickle cell characteristic, but many babies in the United States are now checked as part of their newborn screening. When both parents have the sickle cell characteristic, there’s a 25% possibility that a child will have sickle cell disease. However when one parent is bring the characteristic and the other really has the disease, the odds increase to 50% that their child will acquire the disease.

Who Is Affected?

In the United States, hemoglobin SS disease (sickle cell anemia) impacts mainly African Americans. Nevertheless, kinds of sickle cell disease might occur in individuals with different ethnic backgrounds, such as those whose ancestors originated from Mediterranean nations (consisting of Turkey, Greece, and Italy), East India, or Middle Eastern countries.

Causes of Sickle Cell Disease

Hemoglobin permits red cell to carry oxygen. It is made up of alpha chains and beta chains. A child with sickle cell disease has acquired two unusual genes for the beta chain of hemoglobin.

Hemoglobin can group together abnormally, distorting the shape of RBCs. The cells alter from a regular round, donut shape to the elongated shape of a sickle, or the shape of the letter “C.”.

Unlike typical RBCs, which move easily through little capillary, sickle cells are stiff and pointed. They have a tendency to get stuck in narrow blood vessels and block the flow of blood. This can cause episodes of pain as well as can cause organ damage due to the fact that the tissues aren’t getting adequate oxygen.

Sickle cells have a shorter-than-normal life expectancy, which results in anemia (low RBC count). A regular red cell lives for about 120 days in blood circulation, whereas a sickle cell lives for just 10 to 20 days.

Medical diagnosis

Sickle cell disease usually is detected at birth with a blood test during regular newborn screening tests. If a child tests positive on the screening test, a second blood test (called a hemoglobin electrophoresis) need to be done to verify the medical diagnosis.

Since kids with sickle cell disease are at increased risk of infection and other health complications, early diagnosis and treatment to prevent issues is very important. Presently, all 50 states in the United States require newborn screening programs for sickle cell disease.

Symptoms and signs

Symptoms of sickle cell disease differ, ranging from mild to severe, and might be less severe or different in kids who have actually inherited a sickle cell gene from one parent and a different unusual hemoglobin gene from the other.

Most kids with sickle cell disease have some degree of anemia and may develop several of the following conditions and symptoms as part of the disorder:

Severe chest syndrome: Inflammation, infection, and occlusion (obstructions) of small vessels of the lung might cause this syndrome. Signs include chest pain, coughing, difficulty breathing, and fever.

Aplastic crisis: This is when the bone marrow briefly slows its production of RBCs due to infection (most commonly parvovirus) or another cause, resulting in a serious drop in RBCs and severe anemia. Signs consist of paleness, tiredness, and quick pulse.

Hand-foot syndrome (also called dactylitis): This painful swelling of the hands and feet might be the first sign of sickle cell anemia in some babies.

Infection: Kids with sickle cell disease are at increased risk for specific bacterial infections. It is necessary to look for fevers of 101 ° F( 38 ° C) or greater, which might signify an infection. Children with sickle cell disease and a fever need to be seen by a doctor immediately.

Painful crises: These might take place in any part of the body and may be caused by cold, stress, or dehydration. The pain may last a couple of hours, a few days, or sometimes much longer. Pain may be so severe that a child needs to be hospitalized.

Splenic sequestration crises: The spleen becomes enlarged by trapping (or “sequestering”) the unusual RBCs. This can cause a major and quick drop in the red cell count (severe anemia). Early signs consist of paleness, weakness or tiredness, a bigger spleen, and pain in the abdominal area.

Stroke: Impaired blood flow in the brain can happen when the sickle-shaped cells obstruct little capillary, which may result in a stroke. Signs can consist of headache, seizures, weak point of the arms and legs, speech problems, a facial droop, or loss of consciousness.

Other possible complications consist of leg ulcers, bone or joint damage, gallstones, kidney damage, painful prolonged erections in males (priapism), eye damage, and delayed growth.


Stem cell transplant (likewise called bone marrow transplant) is the only known treatment for sickle cell disease. Transplants are intricate and dangerous procedures, and in the meantime are a choice just for a carefully chosen subset of patients with severe complications.

To be qualified, a child would need bone marrow or stem cells from a “matched” donor with a low risk of rejection. Even then, the procedure has considerable risks and there’s always the chance of rejection of the transplanted marrow.

However even without a treatment, kids with sickle cell disease can lead relatively typical lives. Medicines are offered to help handle the pain, and immunizations and everyday dosages of penicillin (an antibiotic) can assist prevent infection.

Infection used to cause numerous deaths in infants and kids with sickle cell disease. But thanks to penicillin (or a comparable antibiotic, amoxicillin) and suitable immunizations, kids are much more likely to live longer, much healthier lives. Although penicillin isn’t really a treatment, it can help prevent deadly infections due to bacteria that cause serious blood infections, meningitis, and pneumonia.

Most kids will require two daily doses of penicillin, as prescribed by their doctors, until they’re at least 5 years old (and typically older). They likewise ought to be totally immunized with the regular youth vaccinations, as well as the pneumococcal, influenza, and meningococcal vaccines. Folic acid supplements can assist them continue to produce brand-new RBCs.

Often, kids who establish serious complications (such as reoccurring intense chest syndrome, particularly severe anemia, or stroke) might get regular transfusions of red blood cells to avoid or treat these complications.

Hydroxyurea is a medication that increases the quantity of fetal hemoglobin in blood cells, which hinders the sickling procedure and makes RBCs less sticky. This assists decrease the frequency and intensity of painful episodes and other complications such as acute chest syndrome. When taken every day, hydroxyurea has been proven to reduce pain and other complications in kids and grownups. Thankfully, it is likewise really safe and has couple of side effects. More and more kids and adults with sickle cell, consisting of really young children, are taking this drug.

When to Call the Doctor

Seek emergency medical attention instantly if your child develops any of the following:

  • fever of 101 ° F( 38 ° C )or greater
  • pain that isn’t relieved by oral medication
  • chest pain
  • shortness of breath or trouble breathing
  • severe tiredness (exhaustion)
  • severe headaches or dizziness
  • severe stomach pain or swelling
  • jaundice (yellowish skin or whites of the eyes) or severe paleness
  • painful erection in males
  • sudden change in vision
  • seizures
  • weak point or inability to move any part of the body
  • slurring of speech
  • loss of awareness
  • numbness or tingling

Taking care of Your Child

Your child ought to receive routine care from your primary care doctor as well as a hematologist (a blood specialist) or a sickle cell specialty clinic. It is necessary to share your concerns and discuss any new symptoms or complications with your child’s health care group.

Your child likewise should drink great deals of fluids, get a lot of rest, and avoid severe temperatures.

The majority of people with sickle cell disease now live into middle age and typically well beyond. A vital time is the first couple of years of life, which is why early diagnosis and treatment are so essential.
