Maintenance therapy included CS and Azathioprine or Mycophenalate Mofetil. Patients presenting with diffuse alveolar haemorrhage or renal failure received plasma exchange. Rituximab was reserved for patients intolerant or not responding to Cyclophosphamide, or serious relapses, including cerebral vasculitis. Tracheal stenosis (n=1) required recurrent balloon dilatation. Cavitatory pulmonary disease, pneumothorax and aspergillus disease, responded to CS, iv Immunoglobulin and Rituximab.16 patients relapsed requiring further induction treatment. There were 3 deaths, 1 renal transplant, 1 lung transplant, and 1 end stage renal failure on haemodialysis. The majority of patients are asymptomatic on low dose immunosuppression.Conclusions:Pulmonary vasculitis requires a high index of suspicion to ensure prompt diagnosis and treatment to avoid end organ damage.
