Modern therapeutic approach to ANCA-associated vasculitis.

The systemic vasculitis are characterised by an inflammatory process of the blood vessel walls. These may affect any of the vessels and organs, resulting in a diverse range of signs and symptoms. These polymorphic clinical manifestations, combined with the non-specific aetiology of the histological lesions, render the diagnosis for any single form of vasculitis more complicated. The problem lies in the various forms of vasculitis with analogous clinical presentations, requiring very different prognosis and treatment. This review has been realised in order to examine the modern approach to achieve and to maintain the clinical remission and to treat the relapse.
