Summary
The COVID‐19 pandemic has created many challenges in the management of immune thrombocytopenic purpura (ITP). The recommendation for avoidance of steroids by WHO led to the off‐licence use, supported by NHS England, of thrombopoietin mimetics (TPO‐RA) for newly diagnosed or relapsed ITP. This is a real‐world prospective study which investigated the treatment patterns and outcomes in this setting. Twenty‐four hospitals across the UK submitted 343 cases. Corticosteroids remain the mainstay of ITP treatment, but TPO‐RAs were more effective. Incidental COVID‐19 infection was identified in a significant number of patients (9·5%), while 14 cases were thought to be secondary to COVID‐19 vaccination.
Here we present the case of a patient with diffuse large B-cell lymphoma who was admitted to hospital for an elective autologous peripheral blood stem cell transplant after cytotoxic treatment with lomustine, cytarabine, cyclophosphomide and etoposide (LACE). On the final day of chemotherapeutic treatment, she developed sudden onset dyspnoea. Electrocardiography confirmed acute antero-lateral T-wave inversion. She went onto have coronary angiography that demonstrated unobstructed coronary arteries. Left ventriculography demonstrated apical ballooning, consistent with Takotsubo (stress) cardiomyopathy. The link between chemotherapy and Takotsubo cardiomyopathy has become increasingly recognized in recent years, although causality remains to be established and the mechanism of action is not yet fully understood.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
