OBJECTIVE: To examine the role of low-dose glucocorticoids (GCs) in major relapse, hospitalisation and damage accumulation risk during maintenance therapy in anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAVs).
METHODS: Retrospective cohort study of newly diagnosed patients with granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) followed in three tertiary referral centres. We recorded relapses (Birmingham Vasculitis Activity Score increase >0), increases in Vasculitis Damage Index (VDI) and hospitalisations. We used time-varying and mixed-effects Cox models to examine the effect of GCs on the risk of major relapses, VDI accumulation and hospitalisations. Sensitivity analysis was also conducted to address potential confounding.
RESULTS: 171 patients (GPA: 107, MPA: 64, median age: 61 years) were included with a median follow-up of 88.2 months (803.4 patient years (PY)). We recorded 65 major relapses (8.1/100 PY) in 48 patients (28%), 65 events of new damage (8.1/100 PY) and 132 hospitalisations (16.4/100 PY). By multivariable analysis, rituximab use was associated with a lower risk (HR=0.21, 95% CI 0.09 to 0.47, p=0.0001) while disease activity at diagnosis was associated with an increased risk (HR=1.17, 95% CI 1.03 to 1.33, p=0.013) of major relapses. Low-dose GCs were not associated with a reduced major relapse risk (HR=0.96, 95% CI 0.88 to 1.05, p=0.36) but they were associated with a risk of damage accumulation (HR=1.52, 95% CI 1.19 to 1.93, p=0.0007) and hospitalisations (HR=1.24, 95% CI 1.06 to 1.45, p=0.006).
CONCLUSION: Higher GC exposure during maintenance therapy was not significantly associated with a lower major relapse risk whereas it was associated with damage accrual and hospitalisation. These findings may support decision making regarding long-term GC use in patients with GPA/MPA.
