The clinical characteristics, management, and outcome of coronavirus disease 2019 (COVID‐19) caused by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) after solid organ transplant (SOT) remain unknown. We report our preliminary experience with 18 SOT (kidney [44.4%], liver [33.3%], and heart [22.2%]) recipients diagnosed with COVID‐19 by March 23, 2020 at a tertiary‐care center at Madrid. Median age at diagnosis was 71.0 ± 12.8 years, and the median interval since transplantation was 9.3 years. Fever (83.3%) and radiographic abnormalities in form of unilateral or bilateral/multifocal consolidations (72.2%) were the most common presentations. Lopinavir/ritonavir (usually associated with hydroxychloroquine) was used in 50.0% of patients and had to be prematurely discontinued in 2 of them. Other antiviral regimens included hydroxychloroquine monotherapy (27.8%) and interferon‐β (16.7%). As of April 4, the case‐fatality rate was 27.8% (5/18). After a median follow‐up of 18 days from symptom onset, 30.8% (4/13) of survivors developed progressive respiratory failure, 7.7% (1/13) showed stable clinical condition or improvement, and 61.5% (8/13) had been discharged home. C‐reactive protein levels at various points were significantly higher among recipients who experienced unfavorable outcome. In conclusion, this frontline report suggests that SARS‐CoV‐2 infection has a severe course in SOT recipients.  相似文献

Coronavirus disease 2019 (COVID‐19) is a novel infectious disease that continues to spread on a global scale. There has been growing concern about donor‐derived transmissions of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). Herein, we present the case of a patient who underwent ABO‐incompatible living donor liver transplantation without knowing that the liver donor was infected with COVID‐19 during the donation procedure. In this case, the donor‐derived transmission to the recipient was not identified, and the liver donor was found to be recovering from a COVID‐19 infection. The donor‐derived transmission was not identified.  相似文献

This European Society of Coloproctology guidance focuses on a proposed conceptual framework to resume standard service in colorectal surgery. The proposed conceptual framework is a schematic and stepwise approach including: in‐depth assessment of damage to non‐COVID‐19‐related colorectal service; the return of service (integration with the COVID‐19‐specific service and the existing operational continuity planning); safety arrangements in parallel with minimizing downtime; the required support for staff and patients; the aftermath of the pandemic and continued strategic planning. This will be dynamic guidance with ongoing updates using critical appraisal of emerging evidence. We will welcome input from all stakeholders (statutory organizations, healthcare professionals, public and patients). Any new questions, new data and discussion are welcome via https://www.escp.eu.com/guidelines .  相似文献

COVID‐19 has been declared a pandemic by the World Health Organization. As of April 1, 2020, Italy was the country with the second highest number of cases in the world. The spread of COVID‐19 has required a rapid reorganization of health service delivery in face of the pandemic. Breast cancer units have reprioritized their workload to guarantee the health of oncologic patients at the highest risk and regular screening activities. However, at the end of the pandemic emergency, many benign and reconstructive cases will return to our attention and their surgical treatment will be necessary as soon as possible.  相似文献

The practices of head and neck surgical oncologists must evolve to meet the unprecedented needs placed on our health care system by the Coronavirus disease 2019 (COVID‐19) pandemic. Guidelines are emerging to help guide the provision of head and neck cancer care, though in practice, it can be challenging to operationalize such recommendations. Head and neck surgeons at Wuhan University faced significant challenges in providing care for their patients. Similar challenges were faced by the University of Toronto during the severe acute respiratory syndrome (SARS) pandemic in 2003. Herein, we outline our combined experience and key practical considerations for maintaining an oncology service in the midst of a pandemic.  相似文献
