Clinical Phenotypes in Pericarditis: IL-1RA Antibodies and suPAR Levels

Observational Study on Anti-interleukin-1 Receptor Antagonist Antibodies and Soluble Urokinase Plasminogen Activator Receptor (suPAR) in Pericarditis: PERIPLO (PERicarditis: IL-1 RA Antibodies and suPAR Levels Observational) Study

Sponsor

ASST Fatebenefratelli Sacco

Enrollment

146 participants

Start Date

Jul 1, 2023

Study Type

OBSERVATIONAL

Conditions

Pericarditis

Summary

This study aims to investigate the pathophysiology of recurrent pericarditis (RP) by testing for neutralizing autoantibodies against interleukin-1 receptor antagonist (IL-1RA) and measuring soluble urokinase plasminogen activator receptor (suPAR) levels. The hypothesis is that these tests will provide insights into both the inflammatory and non-inflammatory phenotypes of RP, shedding light on the underlying mechanisms. The study will assess the correlation between antibody levels, suPAR levels, and markers of cardiac damage and inflammation. Longitudinal testing during acute episodes and intercritical phases is also planned. The results may guide the use of anakinra, an IL-1 receptor antagonist, in specific clinical scenarios and optimize treatment strategies for RP.

Interventions

DIAGNOSTIC_TESTIL1RA Antibody Assay

-The measurement of anti-interleukin-1 receptor antagonist (IL1RA) antibodies will be performed using the ELISA (Enzyme-Linked Immunosorbent Assay) method,as previously described \[Thurner, L., et al., IL-1RA Antibodies in Myocarditis after SARS-CoV-2 Vaccination. N Engl J Med, 2022. 387(16): p. 1524-1527\].

DIAGNOSTIC_TESTsuPAR Testing

-The quantitative determination of soluble urokinase plasminogen activator receptor (suPAR) levels in blood will be conducted using the commercially available "CHORUS suPAR Extended" kit (cod. 81414, DIESSE Diagnostica Senese S.p.A., Siena, Italy), based on the principle of the sandwich ELISA method.
