Recurrent pericarditis in older adults: Clinical and laboratory features and outcome.

Older adults affected by recurrent pericarditis show a different clinical pattern, with more frequent dyspnea, pleural effusion, severe pericardial effusion, and lower fever and lower leukocyte count, making the diagnosis sometimes challenging. They received significantly less NSAIDs and colchicine, likely due to comorbidities; they were also treated less commonly with anti-IL1 agents, and more frequently with corticosteroids.
