OBJECTIVE: To describe the clinical presentation of the association between pulmonary fibrosis (PF) and systemic vasculitis related to antineutrophil cytoplasmic antibodies (ANCA-V). METHODS: 12 patients (three female, mean age 70.7 years) with ANCA-V associated with "idiopathic" PF were studied retrospectively. RESULTS: ANCA-V and PF were diagnosed simultaneously in eight cases; PF occurred earlier in three cases and during ANCA-V follow-up in one. No patient had intra-alveolar haemorrhage (IAH). ANCA were myeloperoxidase (MPO)-ANCA in all cases. Seven patients had blood eosinophilia at diagnosis. Two patients died during ANCA-V induction therapy. The respiratory status of five patients worsened and three of them died from exacerbation of end-stage respiratory failure. The five remaining patients had a stable respiratory status. CONCLUSION: The association of PF and ANCA-V does not seem to be fortuitous, even though their clinical evolutions are clearly not related. PF was the major cause of death.
