Active clinical trials for "Pericarditis"

Among patients with colchicine-resistant glucocorticoid-dependent idiopathic RP (idiopathic recurrent pericarditis during at least a second recurrence, having met the 2015 European Society of Cardiology criteria for pericarditis at least once), HCQ 400mg daily is associated with a reduce the risk of recurrence. The above hypothesis will be tested with a randomized, prospective, parallel, open label clinical trial. The expected study duration is approximately 12 months from the time the first subject is enrolled (planned for February 2023) to the time of study's termination date (December 2024). The researchers will obtain approval by the institutional review board (IRB).

The registry will focus on furthering the understanding of the natural history of recurrent pericarditis (RP), as well as document RP-related clinical, health-related quality of life (HRQoL), and economic burden and will assist the medical community to refine or develop data-driven recommendations for clinical management of RP patients to optimize clinical outcomes. It also aims to generate data in support of the impact of rilonacept on clinical outcomes in a real-world population.

Myocarditis and pericarditis are inflammatory diseases of the myocardium and pericardium, and can be related to different causes, including vaccines. In the past, some people developed inflammatory heart disease after receiving a live or inactive virus vaccine (smallpox vaccine or flu vaccine). Myocarditis was also seen in people with COVID-19. More recently, many countries reported that some people have developed an inflammatory condition of the myocardium or pericardium after receiving a vaccine for COVID-19. After the COVID-19 vaccination campaigns, doctors have noticed more people presenting to the Emergency Department with chest pain and shortness of breath after receiving the vaccine, symptoms that resemble myocarditis or pericarditis. These symptoms may start between 2 to 10 days following vaccination and are frequently noticed after the second dose of the vaccines. While pericarditis seems to affect people of various age groups and gender, myocarditis is more commonly seen in young males. The study will consist of three components. First, the vaccine-induced inflammatory heart disease registry will be established. It will include a retrospective cohort study (chart review). Second, patients with persistent symptoms will be invited to participate in additional research-blood work and a 3-month telephone interview, as some of the patients may display chronic symptoms after developing the condition. Third, there will be a prospective, pragmatic design case-control study. We will collect clinical information and include blood samples for biomarkers twice for cases and once for controls and retrospective patients with persistent symptoms. Follow-up telephone interview will be conducted at the 3 months, 6 months, 12 months and yearly up to 4 years. A record search will also be performed at 6 months, 12 months and yearly for 4 years. The retrospective component of the study will be conducted by identifying patients previously diagnosed with this condition at participating centres.

The study will aim at investigating novel plasma or imaging biomarkers in patients with acute pericarditis. All participants will be treated according to established clinical recommendations for the diagnosis and treatment of acute pericarditis. Study participants will undergo blood sampling for measurements of plasma biomarkers potentially involved in the pathogenesis of acute pericarditis. Imaging datasets from available imaging tests will be used to quantify imaging biomarkers. Patients will be followed up prospectively for up to 18 months. The prognostic value of plasma and/or imaging biomarkers for development of complications such as atrial fibrillation, pericarditis recurrences, constrictive pericarditis and/or the need to switch to 2nd line treatment will be sought.

Treatment of pericarditis largely remains empirical due to the relative lack of randomized controlled trials. Nevertheless, some recommendations have been formulated to guide management and follow-up of acute pericarditis. Aspirin or an NSAID at medium to high dosages is the mainstay of treatment. Optimal length of treatment is not established. PERICARDITE is a French multicentric placebo controlled double blind randomized trial assessing efficacy of a brief treatment based on Aspirin (4 days) versus a longer treatment (21days) in treating a first episode of probably idiopathic acute pericarditis. It is a non inferiority trial. Exclusion criteria are: diseases known to cause pericarditis: (recent myocardial infarction, autoimmune disease, postpericardiotomy syndromes, connective tissue disease, tuberculosis, neoplastic disease). Primary endpoint is: 30 days recovery defined as the normalization of all clinical and paraclinical initial abnormalities. Secondary endpoint is: 6-month recurrence.

The goal of this study is to determine the safety and efficacy of anakinra for the treatment of acute pericarditis when initiated within 6 hours of diagnosis and continued for 3 or 7 days. to determine the efficacy of anakinra with respect to chest pain resolution to determine the safety of anakinra with respect to adverse drug events

Inflammatory cardiomyopathies are associated with inflammation and impaired function of the heart muscle and encompass myo- and pericarditis and cardiac sarcoidosis. Due to the heterogeneity of the clinical manifestations, establishing the diagnosis and prediction of outcome is challenging. Specifically for myocarditis, it is associated with acute and chronic heart failure and sudden cardiac death. Cardiac magnetic resonance imaging (CMR) allows imaging of tissue characteristics (i.e. edema and fibrosis). CMR is the primary diagnostic tool in myocarditis and can also be used for differentiating other inflammatory diseases. Beside the presence of edema, also hyperemia/capillary leak, fibrosis and myocardial function can be assessed and quantified. Previous studies demonstrated the prognostic role of CMR features beyond traditional markers of LV function, but are limited to smaller cohorts and single-center studies. Furthermore, CMR is a rapidly developing modality and as new features of the modality become available, additional research is needed to identify which combination of parameters optimize risk stratification of this heterogenous inflammatory cardiomyopathy. Hence, the goal of the registry is to investigate the diagnostic and prognostic role of clinical techniques in inflammatory cardiomyopathies, particularly CMR, and which combination of features provide the highest potential. This analysis will include new advanced CMR techniques but will also assess the role of other techniques that may be more cost-efficient and more widely available, which could be used as a precursor to CMR imaging exams.

The purpose of the study is to determine whether colchicine is safe and effective in treatment and prevention of recurrent pericarditis after failure of conventional treatment.

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.

The purpose of the study is to determine whether colchicine is safe and effective in the treatment of acute pericarditis and the prevention of subsequent recurrences.
