Active clinical trials for "Myocarditis"

Arrhythmogenic ventricular cardiomyopathy (AVC) is a genetic condition which affects the heart and can lead to heart failure and rhythm problems, of which, sudden cardiac arrest or death is the most tragic and dangerous. Diagnosis and screening of blood-relatives is very difficult as the disease process can be subtle, but sufficient enough, so that the first event is sudden death. The Mayo Clinic AVC Registry is a collaboration between Mayo Clinic, Rochester, USA and Papworth Hospital, Cambridge University Hospitals, Cambridge, UK. The investigators aim to enroll patients with a history of AVC or sudden cardiac death which may be due to AVC, from the US and UK. Family members who are blood-relatives will also be invited, including those who do not have the condition. Data collected include symptoms, ECG, echocardiographic, MRI, Holter, loop recorder, biopsies, exercise stress testing, blood, buccal and saliva samples. Objectives of the study: Discover new genes or altered genes (variants) which cause AVC Identify biomarkers which predict (2a) disease onset, (2b) disease progression, (2c) and the likelihood of arrhythmia (ventricular, supra-ventricular and atrial fibrillation) Correlate genotype with phenotype in confirmed cases of AVC followed longitudinally using clinical, electrocardiographic and imaging data. Characterize desmosomal changes in buccal mucosal cells with genotype and validate with gold-standard endomyocardial biopsies

BNT162b2 vaccine has become one of the most prevalent vaccines against the COVID-19 and is currently the main vaccine used in Israel. Since marketing and the beginning of use of the vaccine, we and others have reported. of the development of post vaccination myocarditis. In this study the investigators wish to explore the long term impact on 150 patients who have been diagnosed with myocarditis or multisystem inflammatory syndrome (MIS) in the year following their diagnosis of Myocarditis.

Recently chimeric antigen receptor (CAR) T-cell therapy, a new class of chemo therapy, has gained regulatory approval for the treatment of diseases such as B-cell lymphoma. Known side effects include cytokine release syndrome, which has been described to lead to myocarditis, but larger studies exploring this relationship are currently lacking. In this prospective study, the investigators aim to explore the potential effects of CAR T-cell therapy using cardiac MRI on the heart.

This is a national multicenter study in Norway investigating of individuals with Covid-19 vaccine associated myocarditis (VAM) and pericarditis in Norway. The main objective is to validate the reported possible cases of Covid-19 vaccine associated myo-and pericarditis in Norway as well as investigate for predisposing factors and risk factors for developing these vaccine adverse events. Furthermore, patients with confirmed Covid-19 VAM, will be invited to participate in a prospective cohort study, investigating for cardiac long-term adverse effects 1 year and 2 years after vaccine-associated myocarditis.

Anti-cancer immunotherapy, one of the therapeutic revolutions of recent years. It is based on the use of antibodies that block immune system checkpoints that have been hijacked by cancer cells to benefit themselves. Blocking these checkpoints, such as PD-1, unleashes the action of anti-cancer T cells that can then destroy the tumor. The efficacy of these targeted therapies is significant, with an average 40% response rate in patients with metastatic cancers.Immune checkpoint inhibitors (ICIs) are becoming a 1st line therapy in many oncology indications due to their therapeutic line in many oncology indications due to their favorable effect on the prognosis of various prognosis of various cancers Since checkpoints play a key role in controlling the intensity and duration of an immune response, their immune response, therefore, their inhibition exposes to adverse inflammatory or autoimmune effects inflammatory or autoimmune adverse effects that can be severe and sometimes lethal.Most side effects of ICIs occur within the first few months after initiation of treatment. The toxicity of immunotherapy is immunological, all organs including the heart can be including the heart, can be affected. Cardiac autoimmune involvement in ICIs can involve the myocardium, pericardium, and/or vascular endothelium. These entities may be interrelated or, on the contrary, isolated. In the last 5 years, the number of described cases of myocarditis associated with ICIstreatment has increased. Their incidence remains low, estimated between 0.5 and 2%. This probably represents the most serious cardiovascular complication, as the mortality attributed to it reaches almost 50%. In recent years MRI has become very important in the noninvasive diagnosis of acute myocarditis. The latest update of the Lake Louise criteria in 2018 has thus confirmed cardiac MRI in its first place among noninvasive examinations for the diagnosis of myocarditis with a sensitivity of 87.5%, a specificity of 96.2%, and a positive predictive value of 97.2%.

This is a joint project by Sahlgrenska University Hospital: Sahlgrenska, Östra and Mölndal. Our objective is to diagnose and map patients with well phenotyped cardiomyopathies (CMP) including in depth clinical and molecular phenotyping to enable earlier and specific treatment. The project will serve as: resource for diagnostic and therapeutic trials common biomaterial bank resource for detailed molecular analyses on patients' biomaterials and patient specific symptoms and examination results

Cardiac dysfunction is common following hospital admission with sepsis and one of the most frequent causes for readmissions to hospital, however underlying mechanisms by which this might occur are unclear. The CONDUCT-ICU investigators will conduct a pilot, cohort study, characterizing cardiac function in ICU survivors of sepsis using a combination of CMR imaging, biomarkers and patient reported outcome measures to investigate mechanisms of cardiac dysfunction following sepsis. Comparisons will be made to that of the general population.

Myocarditis is an important clinical problem which can can occur as a result of viral infections and autoimmune rheumatic diseases. Cardiac MRI is an important non-invasive means of making a diagnosis. However, current MRI techniques have significant limitations. Firstly, in order to create high-quality pictures, patients are required to hold their breath several times for multiple lengths of time. They often struggle with this due to underlying heart/lung problems. This can adversely affect the overall quality and image interpretation. Secondly, current techniques create 2D images that are potentially underestimating the presence and severity of any tissue inflammation/ injury. This may result in inappropriate treatment, particularly for patients with underlying autoimmune systemic disease who require immunosuppression. Diagnosis by MRI rests on detecting tissue injury through T2 and T1-weighted sequences which detect tissue inflammation and tissue injury. The purpose of this study is to evaluate the diagnostic accuracy of novel 3D free-breathing sequences for T2-weighted and fibrosis/ LGE imaging. Patients with suspected isolated myocarditis (viral/idiopathic) or myocarditis as part of an autoimmune systemic disease will be recruited to ensure that the novel techniques are tested in a broad spectrum of patients with inflammatory heart muscle disease.

It consists of evaluating the advantage of routine detection of phIGFBP-1 to reduce the total duration of hospitalization for patients with a risk of preterm labor before 32 weeks of gestation without increasing the number of preterm labour.

The AMPHIBIA study is an observational ambispective and prospective cohort that aim to describe the histologic, immunologic, biological, imaging, genetic and clinical characteristics of the patients hospitalized for an acute myocarditis and to evaluate their association with prognosis.
