Fulminant myocarditis (FM) is the most severe manifestation of acute myocarditis, an acute inflammatory myocardial disease most often triggered by viral infections.
Currently, the most accepted definition of FM requires acute illness, hemodynamic compromise due to cardiogenic shock, and need for hemodynamic support (inotropes and/or temporary mechanical circulatory support (t-MCS) in the absence of an ischemic cause or other pre-existing cardiomyopathies. Unfortunately, there is a paucity of evidence-based management strategies for this disease and the management of patients affected by FM often varies according to local experience and practice with the role of immunosuppression being the most debated issue.
Besides, due to inconsistent results obtained in several studies and frequent spontaneous recovery with supportive therapy alone, immunosuppression is largely debated in the setting of lymphocytic myocarditis (LM). Among available medications for this disease, corticosteroids are often used despite a lack of clear evidence in the context of FM. Similarly, intravenous immunoglobulin (IVIG) has both antiviral and anti-inflammatory effects on myocarditis. In adults, a recent meta-analysis based on case series showed that IVIG therapy significantly reduced in-hospital mortality, improved the left ventricular ejection fraction, and significantly increased the survival rate in patients with FM. More recently, FM among patients with COVID-19, including post-infectious multisystem inflammatory syndrome, has been reported in young adult patients. These severe forms have been successfully treated with intravenous corticosteroids and IVIG, highlighting the relevance of the systemic inflammatory response in determining cardiac injury in COVID-19, even though more evidence is needed.

Fulminant myocarditis defined by
need for hemodynamic support (inotropes or temporary mechanical circulatory support) for less than 72 hours in the absence of an ischemic cause or other pre-existing cardiomyopathies Noticeably, a coronary angiogram should be performed in patients ≥40 years of age when myocarditis has not been proven histologically. Besides, an endomyocardial will not be mandatory to fulfill the definition of fulminant myocarditis.
Exclusion Criteria:
Age \<15 2. Pregnancy or breastfeeding or baby delivery \<6 months 3. Initiation of inotropes or temporary mechanical circulatory support >72 hours 4. Resuscitation >20 minutes (cumulative low-flow time > 20 minutes ) 5. Pre-existing ischemic or dilated cardiomyopathy or Tako-Tsubo evaluated by echocardiography.
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
PD-1, PD-L1 and CTLA-4 are proteins that act as brakes on the immune system. Checkpoint inhibitors, such as pembrolizumab or nivolumab, block them so the immune system can attack a cancer.
PD-L1 can also be measured in a tumour sample. Some scores count stained tumour cells only (TPS); others also count certain immune cells (CPS). The study names the score and the minimum it uses.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

A composite hierarchical outcome composed of four components : 1) mortality at D28 2) heart transplant/VAD/persisting t-MCS at D28, and 3) number of days alive without t-MCS and inotropes at D28
Each patient will be compared with every other patient in the study and assigned a score (tie: 0, win: +1, loss: -1) for each pairwise comparison based on whom fared better. If one patient survived without heart transplantation or long-term assist ventricular device or t-MCS still ongoing at day 28 and the other does not, scores of +1 and -1 will be assigned, respectively. Otherwise, the assigned score will depend on which patient had more days free from t-MCS and inotropes: the patient with more days off t-MCS and inotropes will receive a score of +1, and the other patient -1. If both patients survived and had the same number of days off t-MCS and inotropes, or if both patients died or had a heart transplant or a VAD, they will be both assigned a score of 0 for that pairwise comparison. For each patient, scores for all pairwise comparisons will be summed, resulting in a cumulative score which will be the primary endpoint of the study.
