Abstract
Pericarditis is the most frequent pericardial disease and presents with a relatively benign course when treated according to guideline-directed therapies at first presentation. Recurrence is the most frequent complication and may occur more frequently after a first episode, in patients with autoimmune etiology, in patients who received glucocorticoids, or after rapid (i.e., within 1 month) tapering of anti-inflammatory drugs. The therapeutic armamentarium for pericarditis includes high-dose nonsteroidal anti-inflammatory drugs (NSAIDs) that are tapered rapidly once symptoms are controlled. Colchicine is necessary to both relieve symptoms and reduce the rate of recurrences and is continued for at least 3-6 months. Low- to moderate-dose glucocorticoids are reserved for patients with a first recurrence for which NSAIDs and colchicine failed and/or who have an autoimmune disorder, with a slow tapering. Interleukin-1 blockers-anakinra, rilonacept, and goflikicept-are used as a third-line option in patients who cannot come off glucocorticoids or as second-line therapy after NSAIDs and colchicine in patients with contraindications to glucocorticoids or in those with high-risk features (i.e., multiple episodes, markedly elevated inflammatory markers, or extensive abnormalities at pericardial imaging) in whom treatment with glucocorticoids is unlikely to succeed.
