RESUMO
Behçet's disease (BD) is a systemic inflammatory disorder of unknown aetiology. Pulmonary haemorrhage from ruptured pulmonary artery aneurysms (PAA) in this condition carries a high mortality but treatment has largely been empiric with use of glucocorticoids and cyclophosphamide. Tumour necrosis factor α (TNF-α) was recently recognised as a mediator in the pathogenesis of BD inflammatory lesions. TNFα inhibitors have been shown in various case reports/series to have beneficial effects in uveoretinitis, entero-Behçet's, neuro-Behçet's and BD arthritis. We describe the efficacy and tolerability of infliximab in 2 patients with Behçet's disease complicated by pulmonary vasculitis admitted to our unit during the years 2004-2015, and discuss the previously published data in this area.
