  • Doctors say there is evidence that a rare inflammatory syndrome being seen in children is connected to the novel coronavirus, according to a new study in The Lancet.
  • At least 100 children around the world have recently been diagnosed with the syndrome, similar to Kawasaki disease, which inflames the walls of the arteries.
  • Until now, scientists have suspected a link but had little data to support it.
  • Doctors in Bergamo, Italy — where cases are up 30-fold — found that 8 out of 10 children who had the syndrome also tested positive for coronavirus antibodies. 
  • But it is still exceedingly rare, and the study estimated it will only affect 1 in 1,000 children exposed to the coronavirus.

Italian doctors have found a “strong association” between the novel coronavirus and a rare condition that has been seen in clusters of children in several countries since the beginning of the pandemic.

The new Kawasaki-like syndrome is also often accompanied by toxic shock, and has seen some children need intensive care. 

Scientists have suspected a link between the two diseases, given the coincidence between the pandemic and the unusual flare-up of the Kawasaki-like syndrome. UK health officials also noted that cases had similar blood profiles to children with severe COVID-19. But without firm evidence, it was not possible to make the connection for sure.

The study took place in Bergamo, one of the cities worst-affected by the coronavirus. At Papa Giovanni XXIII hospital, doctors found that 8 out of 10 children with the condition also tested positive for the antibodies to the coronavirus, technically named SARS-CoV-2. Doctors suspect the other two could be explained by unreliable test results. 

In an accompanying editorial, scientists provisionally named the condition Pediatric Inflammatory Multisystem Syndrome Temporarily Associated with SARS-CoV-2, or PIMS-TS for short. 

Incidences of PIMS-TS increased 30-fold in Bergamo in the space of a month, the doctors said.

However, it is still exceedingly rare, and the study noted that it probably only affects around 1 in 1,000 children exposed to the coronavirus.

What causes a disease like Kawasaki?

Doctors are still studying what could cause the connection between the two diseases. Kawasaki disease is thought to be triggered in some children by an earlier viral infection.
