Recurrent Pericarditis in a Middle-Aged Female with MEFV Mutation.

Recurrent pericarditis (RP) remains challenging, especially in tuberculosis (TB)-endemic regions where empirical anti-TB therapy is often unnecessarily prolonged. We report a 35-year-old woman with three RP episodes over six months, presenting with pleuritic chest pain, elevated inflammatory markers, and moderate-to-large pericardial effusion. Extensive infectious (including TB), autoimmune, and malignancy workups were negative. Cardiac magnetic resonance revealed persistent pericardial late gadolinium enhancement despite clinical remission. Whole-exome sequencing identified a heterozygous MEFV c.442G>C (p.Glu148Gln) variant, suggesting an autoinflammatory predisposition. Although the patient finally achieved sustained symptom-free status for six months on a standardized low-dose colchicine regimen, still over 10% of patients have recurrent symptoms receiving colchicine in addition to conventional anti-inflammatory therapy with aspirin or ibuprofen. This case highlights the shifting paradigm from an infection-centered to an autoinflammatory framework for RP in TB-endemic countries, underscores the role of MEFV variants in idiopathic recurrent pericarditis, and illustrates the real-world gap between genetic insights and therapeutic accessibility to IL-1 inhibitors in resource-limited settings.
