Myopericarditis and thyroiditis: a case report.
Ontology highlight
ABSTRACT: Background
Hyperthyroidism is commonly associated with adverse cardiovascular effects, including tachydysrhythmia, heart failure, and hypertension, although the association between hyperthyroidism and myopericarditis is restricted to a small number of case reports.Case summary
A 45-year-old Caucasian male with no past medical history was admitted with chest pain. The electrocardiogram demonstrated diffuse ST-segment elevation, the troponin T rose, and he was diagnosed with myopericarditis. He was noted to have markedly deranged thyroid function tests and a diagnosis of hyperthyroidism secondary to Graves' disease was made. He was treated with Bisoprolol, Carbimazole, Prednisolone, Ibuprofen, and Colchicine, his symptoms resolved rapidly and he was discharged. Five weeks later he re-presented with similar symptoms and recurrent pericarditis was diagnosed. His symptoms settled with a repeat course of steroids.Discussion
We hypothesize that there may be an underappreciated link between hyperthyroidism and myopericarditis. Potential pathophysiological mechanisms include viral infection, autoimmunity, or changes in myocardial fat metabolism. Suggested management consists of a combination of current guidelines for the treatment of hyperthyroidism and pericardial disease, with attention to certain disease-drug interactions. Further research is required to evaluate the true incidence of hyperthyroidism-associated myopericarditis, elucidate its pathophysiology and instruct management.

Project description:BackgroundThe rapid development of coronavirus disease 2019 vaccines during the pandemic has left their long-term effects largely unknown. Instances of autoimmune and subacute thyroiditis showing features of autoimmune/inflammatory syndrome induced by adjuvants have been reported post-vaccination. This case report aims to highlight the autoimmune/inflammatory syndrome induced by adjuvants syndrome after coronavirus disease 2019 vaccination, drawing attention to a possible connection with thyroid dysfunction and urging for further thorough research.Case presentationWe present a case of thyroiditis induced by the COVISHIELD vaccine in a 37-year-old Indian woman. An apparently normal and healthy adult woman developed neck pain and easy fatigability 2 weeks after the second dose of COVISHIELD, which gradually increased and was associated with irritability, decreased sleep, excessive sweating, tremor, palpitation, and weight loss. She presented to the outpatient department after 1 week of symptoms and was evaluated with laboratory tests and imaging. She was diagnosed with thyroiditis due to the coronavirus disease 2019 vaccine and was treated with propranolol.ConclusionThis case report adds to the growing evidence of coronavirus disease 2019 vaccine-related thyroid issues. The development of thyroiditis is rare and underreported post-coronavirus disease 2019 vaccination; hence, research to evaluate the association of coronavirus disease 2019 vaccines with thyroid dysfunction needs to be done in the future.

Project description:Hydatidosis commonly affect the liver and lungs but in rare cases, it can involve heart tissue. A 42-year-old man from urban areas of Khorasan Razavi province, northeastern Iran, was referred to the cardiac clinic with palpitation, and atypical chest pain in 2018. Large pericardial effusion, reduced left ventricle systolic function was found. A cystic-like lesion was also seen in inter-ventricular septum in echocardiography and high-resolution computed tomography (HRCT). Urgent cardiac surgery was done because of echocardiographic evidence of tamponade. Although the serologic analysis was negative for hydatidosis, surgical excision of cyst and the subsequent histopathological findings revealed a hydatid cyst. In endemic areas, hydatidosis should be considered in differential diagnosis of any cystic-like lesions, even if the serological analysis is negative.

Project description:BackgroundHemophagocytic lymphohistiocytosis (HLH) is a severe disorder characterized by excessive activation of the immune system, leading to hypercytokinemia and damage to multiple organs. We report a rare case of HLH with myopericarditis caused by Campylobacter infection.Case presentationA 28-year-old male patient with a history of hypertension without medicine control presented at the hospital after a four-day fever, decreasing urine amount, rashes on his trunk and limbs, and other symptoms. He was admitted with a provisional diagnosis of atypical infection and allergic skin rash related to diclofenac. However, his condition deteriorated, and he developed shock, tachycardia, chest distress, and bilateral pleural effusion after admission. Further investigations revealed cardiogenic shock related to myopericarditis, and he was transferred to the ICU. In addition, a stool PCR panel subsequently revealed a positive result for Campylobacter. On day 6, he was diagnosed with HLH. Under Clarithromycin and dexamethasone infusion, leukocytosis, anemia and thrombocytopenia with cardiogenic shock status improved. Then, he was later discharged in stable condition.ConclusionsHLH and myopericarditis caused by Campylobacter are very rare. Early detection of Campylobacter-induced HLH and multiple organ failure, as well as prompt use of antibiotics and immunosuppressants, can be helpful for prognosis.

Project description:BackgroundThe effects of hyperthyroidism on the heart are well documented, primarily consisting of supraventricular tachycardias, congestive heart failure, and dilated cardiomyopathy. Acute myopericarditis resulting from a hyperthyroid state is an uncommon but recognized association.Case summaryA 29-year-old man with a history of Graves' disease presented with chest pain and electrocardiogram changes suggestive of an infero-lateral ST-elevation myocardial infarction. However, emergent coronary angiography and bedside echocardiography were normal. Troponin-I was found to be >25 000 ng/L (normal value <57). Thyroid function tests showed a significantly raised free T4 and undetectable thyroid-stimulating hormone. Cardiovascular magnetic resonance (CMR) showed extensive myocardial oedema and late gadolinium enhancement (LGE) in keeping with acute myopericarditis, alongside an enlarged thyroid gland consistent with goitre. Propylthiouracil in combination with an angiotensin-converting enzyme inhibitor and beta-blocker were commenced and eventually definitive treatment with thyroidectomy was performed. Follow-up CMR at 6 months showed complete resolution of the prior noted oedema and a reduction in the location and extent of LGE with significant residual fibrosis.DiscussionAcute myopericarditis is a common diagnosis in young patients presenting with symptoms of chest pain with elevated troponin and is frequently related to a viral illness. Hyperthyroid states are also associated with acute myopericarditis and should be particularly considered in patients with a pre-existing thyroid condition or in those with symptoms suggestive of hyperthyroidism. Given the specific treatments required in a case of myopericarditis associated with hyperthyroidism, it is important to be aware of this association and consider screening where appropriate.

Project description:BackgroundPericarditis is a common cardiology presentation, most often due to a viral or idiopathic cause. Listeria as a cause of pericarditis is rare. Listeria is an infection that is readily treatable with antibiotics following accurate identification. Without adequate treatment, Listeria infection has a high mortality rate.Case summaryIn this case, a fit and well 59-year-old man complained of headaches and fever to the emergency department (ED). He was provisionally diagnosed with giant cell arteritis (GCA) and commenced on management pathways for GCA. He represented to the ED with chest pain and electrocardiogram (ECG) changes suggestive of a clinical presentation of pericarditis. He received treatment for idiopathic pericarditis with no clinical resolution. Cardiac magnetic resonance imaging (MRI) showed myopericardial inflammation associated with a right atrial mural thrombus. After 2 weeks of poor treatment response, peripheral blood cultures grew Listeria monocytogenes and the patient responded well to antibiotic treatment. Repeat cardiac MRI after an extended course of antibiotics showed resolution of MRI signs.DiscussionThis is a case of Listeria myopericarditis. Physicians should consider rarer causes of myopericarditis in treatment resistance cases. Cardiac MRI has utility in atypical or treatment resistant patients to assess myopericardial inflammation and response to treatment.

Project description:Background A global outbreak of the human monkeypox virus (HMPXV), first identified in May 2022, was declared a health emergency of international concern on 23 July 2022. Before the global outbreak, monkeypox cases were mostly confined to central and west African countries, where this virus is prevalent. Close contact, mainly sexual contact, is supposed to be the main route of transmission, and it is remarkable that the incidence is higher in men who have sexual relationships with other men. Case summary A 40-year-old Caucasian man arrived at the emergency department complaining of oppressive epigastric pain extending to the chest after a diagnosis of pharyngitis, which was suspected to be caused by the human monkeypox virus. Based on the clinical symptoms, physical examination, serum cardiac biomarkers, and electrocardiographic findings, he was diagnosed with myopericarditis. The real-time PCR for human monkeypox in skin lesions, urine, plasma, and the oropharyngeal swab was positive. The peak of troponin I was 20.6 ng/ml, and the electrocardiogram showed an upward concavity in the ST segment in diffuse leads, which was in agreement with the previous diagnosis. The presence of edema, subepicardial, and myocardial late gadolinium enhancement, and increased values on T1 mapping in the cardiac MRI were in agreement with the diagnosis of myopericarditis. Antiviral treatment with tecovirimat was started with excellent tolerability. After 6 days, the patient recovered and was discharged. Discussion To our knowledge, this is one of the first reported cases of myopericarditis due to human monkeypox infection, which was confirmed by a cardiac MRI following modified Lake Louise criteria. The short span between the onset of the mucocutaneous symptoms and the myocardial damage suggests a pathogenic association. Furthermore, the active viral replication in plasma samples and the negative results on real-time PCR for other viruses support this clinical association.

Project description:We report a case of overlooked Subacute Thyroiditis (SAT) potentially induced by the administration of a COVID-19 vaccine. This case prompted a thorough review of the existing literature to elucidate possible mechanisms by which immune responses to the COVID-19 vaccine might precipitate thyroid damage. The primary objective is to enhance the clinical understanding and awareness of SAT among healthcare professionals. Subacute thyroiditis is a prevalent form of self-limiting thyroid disorder characterized by fever, neck pain or tenderness, and palpitations subsequent to viral infection. The development of numerous SARS-CoV-2 vaccines during the COVID-19 pandemic was intended to mitigate the spread of the virus. Nevertheless, there have been documented instances of adverse reactions arising from SARS-CoV-2 vaccines, such as the infrequent occurrence of subacute thyroiditis. While the majority of medical practitioners can discern classic subacute thyroiditis, not all cases exhibit typical characteristics, and not all systematic treatments yield positive responses. In this study, we present a rare case of subacute thyroiditis linked to the administration of the SARS-CoV-2 vaccine. A previously healthy middle-aged female developed fever and sore throat 72 h post-inoculation with the inactivated SARS-CoV-2 vaccine. Initially attributing these symptoms to a common cold, she self-administered ibuprofen, which normalized her body temperature but failed to alleviate persistent sore throat. Suspecting a laryngopharyngeal disorder, she sought treatment from an otolaryngologist. However, the pain persisted, accompanied by intermittent fever over several days. After an endocrinology consultation, despite the absence of typical neck pain, her examination revealed abnormal thyroid function, normal thyroid antibodies, heterogeneous echogenicity on thyroid ultrasonography, and elevated levels of Erythrocyte Sedimentation Rate (ESR) and C-Reactive Protein (CRP). These findings led to a consideration of the diagnosis of SAT. Initially, she was treated with non-steroidal anti-inflammatory drugs (NSAIDs) for her fever, which proved effective, but her neck pain remained uncontrolled. This suggested a poor response to NSAIDs. Consequently, steroid therapy was initiated, after which her symptoms of fever and neck pain rapidly resolved.

Project description:BackgroundConcurrent myopericarditis and myositis can present in patients with pre-existing systemic inflammatory diseases. Here we present a case of myopericarditis and myositis associated with COVID-19, in the absence of respiratory symptoms.Case summaryWe present a middle-aged female with a history of hypertension and previous myopericarditis. The patient was admitted with symptoms of central chest pain, and ECG and echocardiographic features of myopericarditis. Her symptoms did not improve, and CT thorax suggested possible SARS-CoV-2 infection for which she tested positive, despite no respiratory symptoms. Whilst on the ward, she developed bilateral leg weakness and a raised creatine kinase (CK), and magnetic resonance imaging (MRI) of her thighs confirmed myositis. A cardiac MRI confirmed myopericarditis. She was treated with colchicine 500 μg twice daily, ibuprofen 400 mg three times day, and prednisolone 30 mg per day, and her symptoms and weakness improved.DiscussionWe describe the first reported case of concurrent myopericarditis, and myositis associated with COVID-19. Conventional therapy with colchicine, non-steroidal anti-inflammatory drugs, and glucocorticoids improved her symptoms, and reduced biochemical markers of myocardial and skeletal muscle inflammation.

Project description:BackgroundBoth acute pericarditis and myocarditis have been reported as rare complications following vaccination with the Pfizer-Biotech and Moderna mRNA COVID-19 vaccines.Case summaryAn 18-year-old man presented with clinical and electrocardiographic changes of acute pericarditis 2 days after receiving the second dose of the BNT162b2 (Pfizer-BioNTech) vaccine. His electrocardiogram also showed an incomplete right bundle branch block. Troponin T on presentation was normal (reference <14 ng/L) but subsequently increased to a peak 1080 ng/L by day 4 post vaccination. Evolving electrocardiographic changes and cardiac MRI findings were consistent with acute myopericarditis.DiscussionThis patient's clinical course was uncomplicated, which is consistent with studies indicating that post-COVID vaccine myocarditis usually has a mild course with a low chance of arrhythmia or heart failure. Troponin elevation is a part of the diagnostic criteria for myocarditis. This case is consistent with another report demonstrating that troponin levels can be within the normal range early in the clinical course of post-COVID vaccine myopericarditis. The incomplete right bundle branch block resolved by day 4 post-vaccination and thus may have represented early myocardial involvement at presentation. Further testing and monitoring should be considered in patients who present soon after COVID-19 mRNA vaccination with pericarditis features or minor conduction delays, in order to rule out progression to myopericarditis. Identifying myocardial involvement is clinically relevant as it indicates a risk of developing arrhythmia or heart failure, as well as having implications for physical activity advice and future booster vaccination.

Project description:BackgroundAcute myopericarditis can be caused by a myriad of infectious and non-infectious aetiologies, however, it is often considered to be due to self-limiting viral infection. Salmonella spp. myopericarditis is rare and the few cases in the literature suggest significant associated morbidity and mortality.Case summaryA 44-year-old man presented with fever, dyspnoea, and chest pain. He was found to have a large pericardial effusion with clinical signs of tamponade and sepsis. Therapeutic pericardiocentesis was performed and ceftriaxone and levofloxacin were administered. Fully sensitive Salmonella enterica serovar Enteritidis (S. Enteritidis) was isolated in his pericardial fluid and he made a full recovery after a 4-week course of ciprofloxacin. A new diagnosis of type 2 diabetes mellitus was made on admission. A follow-up cardiac magnetic resonance (CMR) scan was suggestive of myocarditis which was unexpected given a normal Troponin T level on presentation.DiscussionWe report a rare case of S. Enteritidis myopericarditis. Our case is notable as the patient was immunocompetent apart from newly diagnosed diabetes. This case highlights the value of CMR imaging in assessing for myocarditis and ventricular function.
