Successful use of anakinra for colchicine-intolerant, corticosteroid-dependent recurrent pericarditis secondary to postcardiac injury syndrome after pacemaker placement.

A 54-year-old woman was referred to our centre for the third recurrence of colchicine-intolerant, corticosteroid dependent iatrogenic post-traumatic pericarditis after pacemaker placement 3 months prior to the first episode. The initial episode and each recurrence were associated with a pericardial effusion requiring drainage. Evaluation for pericardial infection, malignancy, autoimmune disease and pacemaker lead perforation was negative. After fourth recurrence and fifth pericardial drainage in 3 months, a trial of anakinra (interleukin-1 inhibitor), in addition to swift symptom resolution successfully prevented subsequent symptomatic and echocardiographic recurrence. Corticosteroids were tapered and eventually discontinued. At 4-month follow-up, the patient continues to be on daily anakinra 100 mg subcutaneous (SQ) daily without adverse effects.
