Medicine will cut ‘shocking’ lung infections in Inuit babies

Indigenous babies in parts of Canada’s north have the highest rates of serious lung infection in the world, research shows.

But it also shows that giving a medicine called palivizumab to prevent infection can dramatically reduce that rate in some regions.

Rates of infection ‘startling’

“The rates of admission (to hospital) were quite startling,” says Dr. Anna Banerji, lead author of the study out of the University of Toronto.

In northern part of the province of Quebec, researchers found almost 50 per cent of all babies were admitted to the hospital with a lung infection in the first year of life. In the western part of the territory of Nunavut, the figure was more than 40 per cent of babies.

“Those are phenomenal numbers,” she says, noting they are higher than in sub-Saharan Africa, Asia, Latin America or anywhere else.

In the hardest-hit places, one infant in every 30 had difficulty breathing and was admitted to intensive care wards in hospitals, most often very far from home.

Several contributing factors

No one really knows why these rates are so high, says Banerji, but contributing factors include overcrowding in homes, poor nutrition and even malnutrition, a lack of breastfeeding, smoking in the home and there may be a genetic component that makes Inuit children more vulnerable to lung infection.

Prevention program will save lives

Banerji is eager to point out the good news in this study. That is, that some 40 per cent of lung infections are caused by the RSV virus and there is an antibody that is effective in preventing infection in up to 96 per cent of cases. And a cost analysis shows that it would be less expensive to prevent infection this way than to treat very sick babies.

As a result of this research, the government of Quebec has decided to implement a prevention program in its northern region of Nunavik. While Banerji says governments must address the underlying factors contributing to infant respiratory infections, the decision to provide the antibody as prevention is a good one.

“I think that’s going to save a lot of hospital admissions, suffering and some lives as well. So, it’s really a good news story.”
