AbstractAcute pericarditis is a disease of the pericardium characterized by inflammation. Around 16-38% of patients develop recurrent events after the first episode. Recurrent pericarditis (RP) seems to be caused by a pathological immune response. An inadequate treatment in terms of drug choice, dose, duration of therapy or tapering, has been shown to increase the risk of recurrences. Symptoms, physical and electrocardiographic signs are usually less severe during a recurrent event as compared to the first episode, thus favoring imaging as a tool to confirm the diagnosis of RP. Cardiac magnetic resonance is becoming the technique of choice because of its ability to detect active pericardial inflammation. Inflammatory biomarkers can be used to assess the risk of recurrences and to guide the tapering of treatments. First-line treatment is based on non-steroidal anti-inflammatory drugs (NSAIDs) and colchicine. NSAIDs are useful for pain control, and colchicine has shown to reduce the risk of further recurrences. Glucocorticoids are often used as second-line drugs, but they are associated with a high rate of recurrent events. Interleukin-1 inhibitors, such as anakinra and rilonacept, significantly reduce the risk of recurrences in patients with RP while on treatment.
