Weathering the Crisis: A Case of Thyroid Crisis with Propranolol-Induced Circulatory Collapse Successfully Treated with Therapeutic Plasma Exchange

Data Analysis and Systematic Scoping Review on the Pathogenesis and Modalities of Treatment of Thyroid Storm Complicated with Myocardial Involvement and Shock

Thyroid storm (TS) is a rare and fatal endocrine emergency that occurs due to undiagnosed and inadequately treated hyperthyroidism after stressful conditions in patients with thyroid disorders. The objective of this systematic scoping review was to better understand the pathophysiology of TS and its complications, in terms of myocardial affection, tachyarrhythmia, and cardiogenic shock. In addition, we explored the pharmacological, mechanical, and surgical treatments for TS. We also evaluated the outcomes of TS according to sex and cardiac involvement. Additionally, analytical analysis was performed on the selected data. A literature review of peer-reviewed journals was carried out thoroughly using medical terms, MeSH on PubMed, Google Scholar, and combinations such as thyrotoxicosis-induced cardiomyopathy, thyroid storm, cardiogenic shock, myocardial infarction, endocrine emergency, Burch-Wartofsky score, extracorporeal circulatory support, and thyroidectomy. A total of 231 papers were eligible (2 retrospective studies, 5 case series, and 224 case reports) with a total of 256 TS patients with cardiac involvement between April 2003 and August 2023. All age groups, sexes, patients with TS-induced cardiomyopathy, non-atherosclerotic myocardial infarction, tachyarrhythmia, heart failure, shock, and different forms of treatment were discussed. Non-English language articles, cases without cardiac involvement, and cases in which treatment modalities were not specified were excluded. Female sex was predominant, with 154 female and 102 male patients. Approximately 82% of patients received beta-blockers (BBs), 16.3% were placed on extracorporeal membrane oxygenation (ECMO) support, 16.3% received therapeutic plasma exchange (TPE), and 13.8% underwent continuous renal replacement therapy (CRRT), continuous venovenous hemofiltration (CVVHD), or dialysis. Overall, 18 females and 16 males died. BB-induced circulatory collapse, acute renal failure, CRRT, and ventricular fibrillation were significantly associated with mortality. Awareness of TS and not only thyrotoxicosis is vital for timely and appropriate treatment. The early diagnosis and management of TS in cardiac settings, including pharmacological, mechanical, and surgical modalities, can save high-risk patients. Sex matters in the presentation, treatment, and mortality of this population. However, further large-scale, and well-designed studies are required.

ABC approach for the management of adults with hyperthyroidism: A practical strategy in primary care

Hyperthyroidism is commonly seen in primary care settings. However, the management of hyperthyroidism might be unclear to primary care doctors. Various guidelines have been published to assist clinicians in the management of thyroid disorders at various levels of care. The extensive coverage of these guidelines may not appeal to busy clinicians, and the guidelines do not focus on often resource-limited primary care settings. In this article, we aim to describe a practical guide for managing hyperthyroidism in primary care settings using an ABC approach.

Comparing the Incidence of Propranolol and Esmolol-Related Cardiac Arrest in Patients With Thyroid Storm: A Systematic Literature Review

A precarious complication of thyrotoxicosis, or thyroid storm, is the increased risk of cardiomyopathy, which leads to circulatory collapse and cardiopulmonary arrest. It is crucial to promptly identify this condition to prevent significant deterioration of the left ventricular function and cardiogenic shock. This article seeks to examine published research that emphasizes the connection between thyroid storm and beta-blocker usage in relation to cardiogenic collapse and provides management recommendations. The search was performed on September 9, 2022, using PubMed, Science Direct, and Google Scholar libraries. A systematic exploration was carried out using the keywords Thyroid Storm AND cardiogenic Shock AND cardiac arrest AND beta blocker. The use of beta blockers as part of thyroid storm management was linked to the development of cardiogenic collapse and cardiac arrest. Ultra-short-acting beta-blockers like esmolol were a safer option than propranolol in treating patients with a thyrotoxic storm.

Cardiovascular Collapse Secondary to Beta-Blocker Administration in a Setting of Coexisting Thyroid Storm and Atrial Fibrillation: A Case Report

A thyroid storm is a rare endocrinological emergency caused by severe hyperthyroidism. Reducing circulating levels of free T3 in blood and beta-adrenergic inhibition are the basis of medical treatment for thyroid storms. Propranolol, due to its additional effect of preventing the peripheral conversion of dormant T4 to active form T3, is the chosen drug for blockade in hyperthyroidism and thyroid storm. We describe a rare clinical case of cardiovascular collapse following propranolol administration in a setting of thyroid storm. The patient presented with symptoms of dyspnea and palpitations and had an ejection fraction of 10%. He was started on a calcium channel blocker (diltiazem). Further investigations revealed that the patient also had a thyroid storm and was immediately shifted to methimazole and propranolol. However, following the administration of a beta-blocker, the patient developed circulatory failure as a result of cardiac arrest, necessitating the use of vasopressors and inotropes. This implores the need for further investigations and treatment regimens for cardiovascular conditions, especially atrial fibrillation arising in thyrotoxicosis, as there are no solid treatment guides in the literature to the best of our knowledge.

Tormenta tiroidea y terapia de intercambio plasmático. Reporte de caso

Introducción. La tormenta tiroidea es una afectación orgánica severa que se produce por la liberación de triyodotironina (T3) y tiroxina (T4). Su incidencia es de 0.20 casos por cada 100 000 habitantes y puede conllevar a una mortalidad de hasta el 30%. Esta es una entidad refractaria para la cual existen pocas opciones terapéuticas, siendo la terapia de intercambio plasmático una estrategia potencialmente útil para su manejo. Presentación del caso. Paciente femenina de 17 años quien ingresó al servicio de urgencias de una institución de tercer nivel de atención por un cuadro clínico de aproximadamente 25 días de evolución consistente en palpitaciones, disnea en reposo, ortopnea, dolor torácico y abdominal, astenia, adinamia, mareo, cefalea y deposiciones líquidas; como antecedentes presentaba hipertiroidismo en manejo ambulatorio. Dada la sintomatología y gracias a que se obtuvo un puntaje de 65 en la escala de Burch-Wartofsky, se diagnosticó tormenta tiroidea, se dio orden de hospitalización y se inició manejo farmacológico, con el cual no se logró una mejoría. Al tercer día de hospitalización la joven presentó deterioro clínico continuo y un episodio convulsivo, por lo que se consideró tormenta tiroidea refractaria que fue tratada satisfactoriamente con terapia de intercambio plasmático como terapia puente previo a tiroidectomía total de urgencia. Conclusión. La terapia de intercambio plasmático permite una rápida remoción de las hormonas tiroideas y, aunque su implementación no es ampliamente difundida por las guías de práctica clínica, existe evidencia que demuestra una disminución en el riesgo de complicaciones perioperatorias y una evolución exitosa tras su uso como terapia puente previo a tiroidectomía en pacientes con tormenta tiroidea refractaria.
