Advances in the Multimodality Imaging and Management of Recurrent Pericarditis: A Contemporary Review

New Developments in the Management of Recurrent Pericarditis.

Recurrent pericarditis is a common and troublesome complication that affects 15%-30% of patients with a previous episode of pericarditis. However, the pathogenesis of these recurrences is not well understood, and most cases remain idiopathic. Recent advances in medical therapy, including the use of colchicine and anti-interleukin-1 agents like anakinra and rilonacept, have suggested an autoinflammatory rather than an autoimmune mechanism for recurrences with an inflammatory phenotype. As a result, a more personalized approach to treatment is now recommended. Patients with an inflammatory phenotype (fever and elevated C-reactive protein level) should receive colchicine and anti-interleukin-1 agents as first-line therapy, whereas those without systemic inflammation should receive low to moderate doses of corticosteroids (eg, prednisone 0.2-0.5 mg/kg/d as an initial dose) and consider azathioprine and intravenous human immunoglobulins in the case of corticosteroid failure. Tapering of corticosteroids should be slow after achieving clinical remission. In this article, we review the new developments in the management of recurrent pericarditis.

Rilonacept and Anakinra in Recurrent Pericarditis: A Systematic Review and Meta-Analysis.

Interleukin 1 (IL-1) has been indicated as a mediator of recurrent pericarditis. Rilonacept, a soluble IL-1 receptor chimeric fusion protein neutralizing interleukin 1 alpha (IL-1α) and interleukin 1 beta (IL-1β), has demonstrated promising results in a phase II study in recurrent or refractory pericarditis. Anakinra is a recombinant inhibitor of the IL-1 receptor with a demonstrated reduction in the incidence of recurrent pericarditis. Definite pharmacological management of pericarditis is key to preventing recurrences, mostly treatment options for recurrent pericarditis refractory to conventional drugs. Here we critically discuss the existing therapy options for recurrent pericarditis, with a focus on new pharmacological approaches: rilonacept and anakinra. A systematic search was conducted across online databases such as PubMed, Cochrane, Google Scholar, ScienceDirect, CINAHL, Scopus, and Embase to obtain clinical trials that assess the effectiveness of anti-interleukin 1 therapy such as anakinra and rilonacept in the management of recurrent pericarditis. Our study concluded that anti-interleukin 1 therapy significantly improved both the quality of life and the clinical outcomes of the study population. These outcomes were most prominent with the use of rilonacept and anakinra in the trial treatment. Rilonacept and anakinra are valuable options in case of recurrent pericarditis refractory to conventional drugs.

Advances in Imaging and Targeted Therapies for Recurrent Pericarditis

Pericarditis is the most common form of pericardial disease. Recurrence of pericarditis affects 15% to 30% of patients after the initial episode of pericarditis. Up to 50% of patients with the first recurrence have additional recurrences. These patients often progress to have colchicine-resistant and corticosteroid-dependent disease. Rapidly evolving cardiac magnetic resonance imaging techniques and novel targeted therapies have paved the way for imaging-guided therapy for recurrent pericarditis. However, the optimal application of these recent advances remains unclear. A search was conducted using the PubMed and Cochrane databases for English-language studies, management guidelines, meta-analyses, and review articles published until April 2022 on recurrent pericarditis. Following the 2015 European Society of Cardiology guidelines for the diagnosis and management of pericardial diseases, new clinical trials and registry data have emerged that demonstrate the efficacy of interleukin-1 blockers in recurrent pericarditis. In addition, new observational data have come to light supporting the use of cardiac magnetic resonance imaging in the diagnosis, risk stratification, and management of such patients. Advances in imaging and targeted therapies have led to a paradigm shift in the management of recurrent pericarditis. This narrative review summarizes the established and emerging data on the diagnosis and treatment of recurrent pericarditis with special emphasis on the role of cardiac magnetic resonance imaging and interleukin-1 blockers in the current era of tailored therapy for recurrent pericarditis.

Recurrent Pericarditis in Children and Adolescents.

Recurrent pericarditis (RP) is a clinical syndrome characterized by recurrent attacks of acute pericardial inflammation. Prognosis quoad vitam is good, although morbidity might be significant, especially in children and adolescents. Multiple potential etiologies result in RP, in the vast majority of cases through autoimmune or autoinflammatory mechanisms. Idiopathic RP is one of the most frequent diagnoses, that requires the exclusion of all known etiologies. Therapeutic advances in the last decade have been significant with the recognition of the effectiveness of anti IL1 therapy, but a correct diagnostic and therapeutic algorithm is of key importance. Unfortunately, most of evidence comes from studies in adult patients. Here we review the etiopathogenesis, diagnosis and management of RP in pediatric patients.
