RESUMO
Background: Immune thrombocytopenic purpura (ITP) refers to immune-mediated destruction of platelets. Viral infections have been proposed as an etiology of ITP; antibodies developed in response to infection may cross-react with normal platelets and result in their destruction. Case Series: We report 2 cases in which coronavirus disease 2019 (COVID-19) likely induced severe ITP. Conclusion: ITP may also play a role in the thrombocytopenia observed in some patients with COVID-19. ITP in this patient population may be more prevalent than currently documented.
RESUMO
Extracorporeal membrane oxygenation (ECMO) is used to provide respiratory and/or circulatory support for critically ill patients. In people suffering from hematologic malignancies (HMs), acute respiratory failure often necessitates intensive care. Whereas initial studies reported that these patients generally have poor outcomes, studies conducted within the last 10 years have shown that ECMO is quite beneficial for patients with HMs. This review showcases data from 2010 to 2019 demonstrating the utility of ECMO in cancer patients. Retrospective studies revealed long-term disease-free survival, particularly when ECMO served as a bridge through chemotherapy. Case reports suggested strong evidence of mortality benefit from ECMO, especially in patients with aggressive lymphomas. However, a systematic approach is needed to better quantify and validate these findings. Studies with larger sample size and prospective cohorts are needed to help create well-defined guidelines for physicians approaching the treatment of cancer patients on ECMO.
