Nearly all children with ANCA-associated vasculitis demonstrate active kidney disease at diagnosis, and their renal function status is strongly predictive of outcomes 1 year later, according to data published in Arthritis & Rheumatology.

SAN DIEGO — Patients with granulomatosis with polyangiitis and microscopic polyangiitis who lower their glucocorticoid dose have an increased risk for death, renal failure, progression or relapse, said a presenter at ACR Convergence 2023.
