Filter by: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%.
From May 2020 to May 2021, the investigators retrospectively evaluated clinical cardiac magnetic resonance (CMR) examinations performed in patients with suspected cardiac involvement post COVID-19. Between May 2021 and August 2021, the investigators evaluated patients with suspected cardiac disease after COVID-19 vaccination.
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.
This study evaluates positron emission tomography for the diagnosis of immune checkpoint inhibitor-related myocarditis. Immune checkpoint inhibitors have shown promising results in various malignancies however, several immune related adverse events have been described of which myocarditis carries the highest reported mortality. Diagnostic procedures, such as positron emission tomography, help find and diagnose myocarditis and provide functional or disease activity information as opposed to the largely structural/anatomic information.
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 focus on cardiac blood and imaging biomarkers to facilitate early recognition of patients at risk for myocardial injury after COVID-19 vaccination. Ultimately, the intention is to identify patients at risk, reduce adverse events, and determine the need for longer-term follow-up in patients with myocardial injury after vaccination.
The study will evaluate myocardial inflammation in cyclists after high intense and sustained exercise. Our hypothesis is that strenuous exercise in recreational cyclists may be associated with myocardial inflammation. Myocardial fibrosis in asymptomatic athletes is associated with life-threatening arrhythmic events and sudden death. Although myocarditis seems to be the most likely underlying cause, it remains unclear if strenuous and sustained physical exercise can cause myocardial inflammation with development of myocyte necrosis and possibly myocardial fibrosis in athletes. Nineteen recreational cyclists performing "L'ETAPE DU TOUR (EDT) de France" a cycling ride (175 km, 3600 m of positive altitude difference) on July 4 2021 will be included in this study. In part 1 of the study, each participant will complete a detailed questionnaire detailing their training history and an echocardiography at rest will be performed. All participants will have exercise testing approximately 1 week before the EDT stage to set aerobic and anaerobic gas exchange thresholds, as well as VO2max.
As of March 2020, COVID-19 has become a global pandemic, halting athletic competition worldwide. Reports from China show a high prevalence of cardiac involvement in patients with severe SARS-CoV-2 infection. These cardiac forms were found to be closely associated with adverse outcomes. The use of Magnetic resonance Imaging (MRI) had allowed to show that cardiac dysfunction could be mediated by myocardial inflammation (i.e. myocarditis). The direct implication of the virus was demonstrated with Severe Acute Respiratory Syndrome (SARS)-CoV-2 being detected on myocardial biopsies in a patient with severe heart failure. The experience with other viruses causing acute myocarditis shows that there is a high rate of undetected injuries. Indeed, although severe heart failure can be present at the acute stage, acute viral myocarditis is most commonly pauci or asymptomatic, but still leaving occult myocardial scars visible on MRI, and exposing to higher risks of ventricular arrhythmia and sudden cardiac death over the long term. Although athletes are younger and have fewer comorbidities than the general population and therefore are at lower risk for severe disease or death, there is a critical and urgent need to assess the prevalence of occult scars in the population of high-level athletes returning to training after the SARS-CoV-2 pandemia.
The aim of this study is to determine whether there is a higher prevalence of perimyocarditis after undergoing vaccination for Covid-19.
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.
