The advent and implementation of newborn screening have increased the prevalence to approximately one in 58,000 children diagnosed each year. While SCID was previously thought to affect approximately one in 100,000 in the US. 1. Better Screening Protocols Allow for Earlier and More Diagnoses ![]() Though his life was short-lived, his advocacy and help propelling research forward for SCID are etched in medical history forever.įor those interested in SCID, here are five more facts you should know. To SCID families, David is a hero and the epitome of strength and hope. ![]() ![]() Photos of him in his protective bubble, designed to act as a barrier between him and outside bacteria and germs, captivated the hearts and minds of all who followed his story. The story of David Vetter, known as the “Bubble Boy” in the 70s and 80s, brought SCID to the forefront of the medical community and the world. SCID-ADA is the second most prevalent type of SCID, identified in approximately 15 percent of cases. X-linked SCID (primarily affecting boys), is the most common form, representing about 40 percent of SCID cases. Currently, there are at least 13 different types of identified SCID, with various “unknown” types still being discovered. Within the past 30 years or so, particularly for X-linked and SCID-ADA, an enormous amount of progress has been made in attempting to identify, research and treat this rare syndrome. #Severe combined immunodeficiency scid trial#I am forever indebted to my parents for being willing to take part in what was probably the most experimental and controversial clinical trial at the time, while still caring for two other kids with physical disabilities, and the doctors who chose to invest in rare disease research. I was able to receive enzyme replacement therapy for SCID-ADA, which kept me alive until I took part in the first gene therapy trial in the world, at 4 years of age, in 1990, at the National Institutes of Health. To parents reading this: I’m even luckier than I previously admitted. My parents relentlessly pursued over 40 doctors within those two years to be able to put a name to what was causing my symptoms and failure to thrive. Reported clinical cases revealed babies with SCID were at an increased risk for developing infections that had the potential to become fatal without a functioning immune system to fight it.Īs someone born before the diagnostic measures and transformational treatments available today, I consider myself lucky to have even received a clinical diagnosis at only 2 years old. The first molecular cause of SCID (adenosine deaminase deficiency or “ADA”) was identified in 1972. Babies born with SCID typically only have a few years to live without any type of medical intervention or treatment to address their weakened immune system.Īccording to various medical journals, the first case of SCID found in humans was reported in 1950. The diagnosis is considered a pediatric emergency. It is the result of genetic mutations that primarily affect the T cells, and often at least one other type of immune cell. ![]() Severe combined immunodeficiency (SCID) is a type of primary immunodeficiency, meaning some of the necessary parts to build a functioning immune system are either missing or not working in the body. ![]()
