SCID WHAT IS IT FULL

Hematopoietic (blood-forming) stem cell transplantation is the standard treatment for infants with SCID. Today, all newborns in the United States are screened for SCID. Department of Health and Human Services’ Recommended Uniform Screening Panel for newborns. Research supported by NIAID and other organizations has shown that early diagnosis of SCID through newborn screening leads to prompt treatment and high survival rates. To confirm a SCID diagnosis, a doctor will evaluate the numbers and types of T and B cells present and their ability to function. Because infants with SCID have few or no T cells, the absence of TRECs may indicate SCID. The SCID newborn screening test, originally developed at NIH, measures T cell receptor excision circles (TRECs), a byproduct of T-cell development. Candida (yeast) infections of the mouth and diaper area and pneumonia caused by the fungus Pneumocystis jirovecii also are common.

Symptoms of SCID occur in infancy and include serious or life-threatening infections, especially viral infections, which may result in pneumonia and chronic diarrhea. As a consequence, they have low numbers of T cells and natural killer cells, and their B cells do not function. Boys with this type of SCID have white blood cells that grow and develop abnormally. X-linked SCID, which is caused by mutations in a gene on the X chromosome, primarily affects male infants. The best-known form of autosomal recessive SCID is caused by adenosine deaminase (ADA) deficiency, in which infants lack the ADA enzyme necessary for T-cell survival. Most often, SCID is inherited in an autosomal recessive pattern, in which both copies of a particular gene-one inherited from the mother and one from the father-contain defects. More than a dozen genes have been implicated in SCID, but gene defects are unknown in approximately 15 percent of newborn-screened SCID infants, according to an NIH-funded study. However, development of a newborn screening test has made it possible to detect SCID before symptoms appear, helping ensure that affected infants receive life-saving treatments. More than 80 percent of SCID infants do not have a family history of the condition. The condition is fatal, usually within the first year or two of life, unless infants receive immune-restoring treatments, such as transplants of blood-forming stem cells, gene therapy, or enzyme therapy. Infants with SCID appear healthy at birth but are highly susceptible to severe infections.

Please see the Full Prescribing Information.Severe combined immunodeficiency (SCID) is a group of rare disorders caused by mutations in different genes involved in the development and function of infection-fighting immune cells. Revcovi ® (elapegademase-lvlr) is indicated for the treatment of adenosine deaminase severe combined immune deficiency (ADA-SCID) in pediatric and adult patients. You are encouraged to report negative side effects of prescription drugs to the FDA.

If you are pregnant or planning to become pregnant, or breastfeeding or planning to breastfeed, please talk to your doctor.

What is known about taking Revcovi during pregnancy? If an ongoing decline in your blood’s measured adenosine deaminase (ADA) activity occurs, your immune function and clinical status will be monitored closely and precautions will be taken to help reduce your risk of infection.

This monitoring will ensure you are maintaining appropriate levels for therapeutic benefit.

While you are being treated with Revcovi, your doctor will need to do blood tests to monitor the levels of ADA activity and metabolites and overall immune function.

Continuous therapy and adherence to the recommended drug schedule is important for the success of the treatment.

What types of monitoring will be needed while I am taking Revcovi?

Cancers of the immune system called lymphomas.

Skin-related problems: redness and itching at the injection site.

Blood and blood cell–related problems: red blood cells being destroyed faster than they can be made, resulting in anemia and higher or lower than normal number of platelets in the blood.

Based on reports of side effects of other enzyme replacement therapies used to treat ADA-SCID, which are similar to Revcovi, patients taking Revcovi may also experience:.

Cough and vomiting were the most common side effects reported by patients receiving Revcovi.

What are the possible side effects of Revcovi? During this delay, it is important to be protected from exposure to infections until your immune system improves.

There may be a delay in improvement of your immune system’s function after starting Revcovi treatment.

Your doctor should not prescribe Revcovi if you have severely low blood platelet counts.

If you have lower than normal platelet counts, you may be at increased risk of bleeding at the injection site.
