Canadian Paediatric Society eyes mysterious syndrome for suspected COVID links

May 6, 2020 | 1:12 PM

TORONTO — The Canadian Paediatric Society is closely monitoring reports that COVID-19 may be linked to a strange inflammatory syndrome in some children.

The society says it expects to issue advice to clinicians late this week or early next about symptoms similar to Kawasaki disease, although a COVID-19 connection has not been established.

A broad study is underway with the Canadian Paediatric Surveillance Program to detect how, and how many, children are being severely affected by COVID-19. A spokeswoman says that would include any cases that suggest Kawasaki disease, the primary cause of acquired heart disease among children.

An infectious diseases pediatrician at Sainte-Justine Hospital in Montreal says COVID-19 is believed to be a factor in more than a dozen cases of Kawasaki-like illness there.

Dr. Fatima Kakkar says the cases emerged over the last three to four weeks and that it’s unusual to see so many within that time period.

None of the kids tested positive for an active COVID-19 illness, but because Kawasaki is believed to be triggered by a viral infection, she says doctors suspect there may have been a past COVID infection that was never detected.

Typically, Kawasaki disease cases emerge once every two weeks at most, Kakkar added.

“Thanks to the containment and social isolation (measures), there are no other viruses circulating,” Kakkar said Wednesday. 

“We definitely don’t want to make the 100-per-cent link because we don’t have that proof yet, but it is suspicious. And I think with the other countries coming up with their data, it does raise the fact that the most likely virus circulating right now is actually COVID.”

Similar cases have been reported in the United States and Europe. This week, New York City’s health department issued an alert about 15 cases, and stressed that early recognition and specialist referral was “essential.”

Kakkar says she and her colleagues must now determine whether the patients — who range in age from one year to late teens and have all recovered — had a past COVID-19 infection, but antibody tests are not yet available in Canada.

She says efforts are underway to get a clinical test validated, or test the children as part of a research protocol.

Canada’s chief public health officer also addressed the issue Wednesday, cautioning parents that children with COVID-19 have mild symptoms and that severe outcomes are very unusual.

Still, Dr. Theresa Tam said parents who are concerned should contact their health-care provider.

“Pediatricians are very aware of Kawasaki disease because it actually happens with other viral illnesses and infections as well. So it’s not specific to COVID-19 and they would know how to manage that.”

Symptoms of Kawasaki disease include rashes, fever, and swelling in the palms and in soles of the feet.
