[What's new in recurrent pericarditis in 2011?].

Recurrent pericarditis are common and their management remains a matter of debate. Their precise pathophysiology is unclear, and both innate and adaptative immunity seem involved. An extensive work-up seeking for etiology seems to be unnecessary during the first episode of acute pericarditis, whereas it is mandatory in recurrent pericarditis. Despite extensive investigations, up to 80 % of recurrent pericarditis remains of unknown origin. Colchicin associated to non steroidal antiinflammatory drugs is the first line treatment whereas immunosuppressive drugs are exceptionally required.
