Ontario celebrates first anniversary of "bubble boy" testing as new study shows it is twice as common among newborns

OTTAWA, Aug. 20, 2014 /PRNewswire/ - Newborn Screening Ontario (NSO), based at the Children's Hospital of Eastern Ontario (CHEO), this month celebrates the first anniversary of screening newborns across the province of Ontario for Severe Combined Immune Deficiency (SCID), a deadly disorder previously known as "Bubble Boy Disease".  According to a new study published today in the Journal of the American Medical Association, SCID affects 1 in 58,000 newborns, not 1 in 100,000 as previously thought.

Ontario, where 40% of Canadian babies are born, is the only jurisdiction in Canada to test every infant born for SCID, a genetic disorder that is only detectable with screening. Since August 2013, thanks to funding from Ontario Ministry of Health, NSO has tested over 145,000 babies for SCID using a new testing approach that was pioneered in the laboratory at CHEO. At least 1 baby has been diagnosed with SCID and is receiving lifesaving treatment.

There are usually no clues at birth that a baby has SCID, although these babies are prone to recurrent, life-threatening infections in the first 6 months of life because of faulty immune systems. They eventually die from complications. Prior to screening, many infants with SCID would not receive a diagnosis until it was too late for treatment to be effective. SCID can often be cured with a bone marrow transplant.

 "We are pleased to see a collaboration of this magnitude amongst our newborn screening colleagues in the US as we complete our first full year of SCID screening," says Dr. Michael Geraghty, Medical Advisor for Newborn Screening Ontario. "We have already identified and diagnosed some children with SCID, but it will be some time before we are able to determine its true prevalence in Ontario."
