SCID is a very rare disease that can be deadly. It causes a child to have a very weak immune system. As a result, the child is unable to fight off even mild infections. The disease is also known as the “boy in the bubble” syndrome because living in a normal environment can be fatal to a child who has it. This disease is passed down from parents to child (inherited).
Children with SCID become very sick with infections such as pneumonia, meningitis, and chickenpox. They can die before they reach their first birthday. But treatments are available that can be successful.
Many genetic problems can cause SCID. These problems make the white cells in the blood (T and B cells) less able to fight infection. The child's immune system has trouble defending the body against bacteria, viruses, and fungi.
There are several types of SCID. The two most common types are classical X-linked and ADA deficiency.
Symptoms of SCID usually start within the first year of a child’s life. The following are the most common symptoms of SCID. But symptoms can occur a bit differently in each child.
Usually the child will have many serious infections, life-threatening infections, or both. The infections are not easily treated. And medicines to treat the infections do not work well. Common infections include:
Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is.
Treatment for SCID includes:
The best treatment for this disease is a bone marrow transplant, which offers a chance of a cure. In a bone marrow transplant, bone marrow cells are transplanted from a healthy person to the child. Bone marrow is the soft, spongy tissue found inside the bones. It helps blood cells form, and is the place where the body stores blood cells.
A bone marrow transplant has the best chance of working if it is done during a child’s first 3 months of life. The goal of bone marrow transplant is to help the child’s immune system work better. Cord blood may also be used for the transplant.
Researchers have had some success using gene therapy to treat SCID. But gene therapy is still in the experimental stages.
