The role of plasma exchange in antineutrophil cytoplasmic antibody-associated vasculitis: a meta-analysis.

The present meta-analysis does not support the wide use of PLEX for the management of AAV in routine clinical practice. Future well-designed randomized controlled trials focusing on specific disease-related manifestations are necessary to reach firm conclusions about the potential efficacy of PLEX. Key Points • PLEX is not widely recommended for the management of ANCA-associated vasculitis. • PLEX performance may reduce the overall incidence of ESRD in severe ANCA-associated vasculitis. • Well-designed randomized controlled trials focusing on specific disease-related manifestations are necessary to reach firm conclusions about the potential efficacy of PLEX on AAV-related outcome.
