Canada: New HIV strains in Saskatchewan lead to faster progression of illness

Mutated strains of HIV circulating in Saskatchewan are leading to faster-developing AIDS-related illnesses in the Indigenous population, new research has shown.

The research from the B.C. Centre for Excellence in HIV/AIDS and Simon Fraser University was presented at the 2018 AIDS Conference in Amsterdam on Thursday. It showed that the strains of HIV in Saskatchewan have high levels of immune-resistant mutations compared to ones in other areas of Canada and the United States.

"Physicians were saying, 'There's something going on here that isn't right, people are getting sick very, very fast,'" said Zabrina Brumme, the lead author of the study and an associate professor of health sciences at Simon Fraser University.

"It's almost as if the virus is nastier."

Saskatchewan's HIV incidence rates are among the highest in North America, with 2016 rates in some areas more than 10 times the national average. Nearly 80 per cent of people with HIV in the province are Indigenous.

The researchers hypothesized that the quickly developing illnesses were linked with resistant strains that had adapted to the specific immune profile of Indigenous people.

"In Saskatchewan, like other places in the world, HIV is adapting to the host populations in which it is circulating," Brumme said.

"In Saskatchewan, the majority of HIV-affected persons are of Indigenous ancestry so HIV, as a result, has adapted to these populations." Read more via CBC
