VPPRN Patient-Powered Research
Microscopic Polyangiitis (MPA)
Every 6 months, we ask our VPPRN community to check-in and tell us how they are doing. The graphs below reflect the scores/ratings of patients with microscopic polyangiitis (MPA) compared to the Network as a whole. Here is what we learned about flares, fatigue, pain, symptoms of vasculitis, and members’ current state of vasculitis at the January 2026 check-in:
- Compared to patients with other forms of vasculitis, patients with MPA reported the following:
- less flares reported
- similar scores for fatigue
- higher percentage of patients with GCA reporting no symptoms over the past 28 days
- similar scores for pain
- a smaller percentage of patients with MPA reported their vasculitis as currently active.
- Compared to patients with other forms of vasculitis, patients with MPA reported the following:
If you have concerns about your health scores, please discuss with your rheumatologist or primary care provider.
