Certain proteins causing severe Covid cases in children?

Since the start of the pandemic, a tiny proportion of children have been affected by Covid-19.

However, some have contracted serious forms which have manifested themselves in particular by heart problems and respiratory distress.

After studying the question for more than two years, researchers from the Murdoch Children's Research Institute (MCRI) in Melbourne (Australia) seem to have put their finger on the answer, published in a study relayed by

and Capital.

85 specific proteins discovered in the blood

The scientists compared the blood samples of 33 children suffering from these symptoms but also from fever, abdominal pain or vomiting, with those of 20 healthy children.

They then discovered that the former contained 85 specific proteins in their blood that the latter did not have, including 52 directly linked to acute respiratory distress syndromes.

However, these so-called “immune” proteins were affected when these children contracted Covid-19, which explains the development of particularly serious syndromes.

In this case, this major discovery should allow researchers to develop a treatment adapted to these specific cases.

International support

According to

, the few children affected by severe cases of Covid-19 were previously treated with intravenous immunoglobulins (IGIV) to reduce their risk of developing heart disease by 25% to 5 %, without necessarily having an effect on the other symptoms.

For this study, samples were sent from France, as serious cases contracted by children were insufficient in Australia.

Conversely, a treatment developed by Australians could, in the future, serve the entire international community.
