Costs of Disease Relapses Among Individuals with Granulomatosis, with Polyangiitis, or Microscopic Polyangiitis in the United States.

ABSTRACT:

Introduction

Granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) are two related forms of systemic vasculitis. Patients with these conditions often experience relapses affecting various body systems.
