What did we do?

Using a population-based database that includes all people living in British Columbia, we looked at the rate of venous thromboembolism (blood clots) in patients diagnosed with GPA compared to the general population (people who did not have GPA).

What did we find?

Patients with granulomatosis with polyangiitis (GPA, formerly known as Wegener’s disease) have a much higher risk of blood clots in the lungs and legs. For GPA patients, it is recommended more attention should be given to monitor for these complications, especially early after diagnosis.

Exploring a New Immune Cell Therapy for People with Autoimmune Diseases

Systemic sclerosis and systemic lupus erythematosus are serious autoimmune diseases that can cause damage to many organs including the skin, lungs and kidneys. In this project, we will study a new type of treatment that may better control these diseases by targeting the immune cells that cause them. If successful, it could reduce inflammation, slow or stop disease progression, and may even help reset the immune system, so that some patients no longer need long-term immune-suppressing medications.

Understanding how scleroderma affects people over time

People living with scleroderma experience challenges such as pain, disability, and mental health concerns, but we still don’t know much about how these problems change over time or why some people do better than others. For this research project, our goal is to improve our understanding of how scleroderma affects people’s daily lives and identify factors that may predict changes in their health.

How can we help Canadians age at home to improve health outcomes and support a sustainable healthcare system?

As Canada’s population ages, home care is important for helping older adults remain safely within their homes. Our research team is linking data from the Canadian Longitudinal Study on Aging with health records in British Columbia, Ontario, and New Brunswick, to track patterns of paid and unpaid home care use over time.
