Objective:
To report on a large series of patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and bronchiectasis, with a specific focus on the timeline of occurrence of both features.
Methods:
Retrospective nationwide multicenter study of patients diagnosed with both AAV and bronchiectasis.
Results:
Sixty-one patients were included, among whom 27 (44.25%) had microscopic polyangiitis (MPA), 27 (44.25%) had granulomatosis with polyangiitis (GPA), and 7 (11.5%) had eosinophilic GPA. Thirty-nine (64%) had myeloperoxidase (MPO)-ANCA and 13 (21%) had proteinase 3-ANCA. The diagnosis of bronchiectasis either preceded (n = 25; median time between both diagnoses: 16 yrs, IQR 4-54 yrs), was concomitant to (n = 12), or followed (n = 24; median time between both diagnoses: 1, IQR 0-6 yrs) that of AAV. Patients in whom bronchiectasis precedes the onset of AAV (B-AAV group) have more frequent mononeuritis multiplex, MPA, MPO-ANCA, and a 5-fold increase of death. The occurrence of an AAV relapse tended to be protective against bronchiectasis worsening (HR 0.6, 95% CI 0.4-0.99, P = 0.049), while a diagnosis of bronchiectasis before AAV (HR 5.8, 95% CI 1.2-28.7, P = 0.03) or MPA (HR 18.1, 95% CI 2.2-146.3, P = 0.01) were associated with shorter survival during AAV follow-up.
Conclusion:
The association of bronchiectasis with AAV is likely not accidental and is mostly associated with MPO-ANCA. Patients in whom bronchiectasis precedes the onset of AAV tend to have distinct clinical and biological features and could carry a worse prognosis.
