Use of Anakinra in steroid dependent recurrent pericarditis: a case report and review of literature

Anakinra in idiopathic recurrent pericarditis: a comprehensive case series and literature review

OBJECTIVE

Idiopathic recurrent pericarditis (IRP) is defined by recurring episodes of pericardial inflammation without a known cause. This study investigates the safety and efficacy of anakinra, an interleukin‑1 inhibitor, as a successful therapy for IRP in cases resistant to conventional treatment.

METHODS

A retrospective evaluation of patients treated at our autoinflammatory center between 2011 and 2023 was conducted. Patient files were examined for demographic, clinical, and treatment response data, including nonsteroid anti-inflammatory drugs (NSAIDs), corticosteroids, and colchicine. Monogenic autoinflammatory disease screening was performed for Mediterranean Fever (MEFV), tumor necrosis factor receptor-associated periodic syndrome (TRAPS), mevalonate kinase (MVK), nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing-3 (NLRP3), and nucleotide-binding oligomerization domain-containing protein 2 (NOD2). Patients who experienced multiple episodes of pericarditis were diagnosed with recurrent pericarditis. The study evaluated anakinra treatment in IRP patients unresponsive to conventional therapy.

RESULTS

The study included 21 participants, 9 (42.9%) female and 12 (57.1%) male. The average age of the participants was 43.1 ± 16.5 years. The MEFV mutation analysis revealed that 2 (9.5%) had a mutation in exon 10 and 4 (19.0%) had one in exon 2. Out of the 16 cases, 15 successfully discontinued steroid treatment. Four patients (19.0%) experienced injection site reactions. C‑reactive protein (CRP) levels were measured at an average of 196 ± 67.8 mg/l before and 2.6 ± 3.15 mg/l after anakinra treatment.

CONCLUSION

In conclusion, the study adds to the growing evidence for the efficacy of interleukin-1 inhibitors, such as anakinra, as a promising treatment modality for IRP in cases resistant to conventional treatment.

Efficacy of Anakinra in Pericarditis: A Systematic Review

Inflammation of the pericardium is referred to as pericarditis, which can cause sharp chest pain and has a high chance of recurrence even after treatment. This review will explore anakinra, which is an interleukin-1 receptor antagonist, as a potential new treatment for pericarditis. The systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines by searching PubMed and GoogleScholar from the years 2012 to 2022. After applying inclusion and exclusion criteria, thorough screening, and quality appraisal, a total of eleven studies were included in the review; eight case reports and three clinical trials. All studies showed that 100 mg/day of anakinra caused a remarkable improvement in patient outcomes. In addition, the pericarditis resolved quicker and had a lower chance of recurrence in comparison to conventional therapy.
