Current treatment of recurrent pericarditis: safety considerations and future directions.

INTRODUCTION: Recurrent pericarditis is one of the most troublesome complications of pericarditis affecting a substantial amount of patients and often severely impairing the quality of life. Current medical treatments range from non-steroidal anti-inflammatory drugs (NSAIDs), colchicine, and corticosteroids to biological agents (anti IL-1 agents, especially anakinra and rilonacept), intravenous immunoglobulins and immunosuppressive treatments. Safety is a major issue to deal with since the disease often affects relatively young or middle-aged patients.

AREAS COVERED: The review is aimed at providing an update on the efficacy and safety of current medical therapies for recurrent pericarditis including most recent advances represented by anti IL-1 agents.

EXPERT OPINION: Therapy of recurrent pericarditis has evolved over years leading to a more evidence-based and personalized treatment based on clinical presentation and pathophysiology. The main distinction is between patients with an inflammatory phenotype (e.g. fever, elevation of markers of inflammation, pericardial, and/or pleural effusion) vs. those without an inflammatory phenotype. Colchicine and anti IL-1 agents are especially efficacious and indicated for those with an inflammatory phenotype, while corticosteroids, azathioprine, and immunoglobulins seem more indicated for those without evidence of systemic inflammation.
