A patient has a fourth episode of idiopathic pericarditis despite adherent colchicine. Each attempt to reduce prednisolone below 10 mg triggers a CRP-positive relapse, CMR still shows pericardial inflammation, and infection, malignancy and systemic autoimmune disease have been excluded. Which steroid-sparing strategy best fits this phenotype?

Correct answer: ARefer for interleukin-1 blockade with a specialist corticosteroid-tapering plan

Colchicine-resistant, corticosteroid-dependent recurrent pericarditis with objective inflammation is an IL-1-driven phenotype in which IL-1 blockade can rapidly control disease and permit supervised steroid withdrawal. Azathioprine has a slower onset and is not the preferred rapid targeted option here. IVIG is reserved for selected refractory circumstances, indefinite prednisolone perpetuates toxicity and recurrence, and pericardiectomy is a later option after medical strategies fail.
