Transplantation of organs from SARS-CoV-2-positive donors: Preliminary experience from Spain.

BACKGROUND: The utilization of non-lung organs from deceased donors with a positive polymerase chain reaction (PCR) for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at the time of donation can be lifesaving, although the safety of this policy must be assessed. METHODS: This is a nationwide, prospective study, reporting the experience on the utilization of non-lung organs from SARS-CoV-2-positive donors between December 15, 2020 and May 31, 2022 in Spain. RESULTS: A total of 69 patients received a solid organ transplant (41 kidney, 18 liver, 8 heart, and 2 combined liver-kidney) obtained from 32 donors with a positive SARS-CoV-2 PCR at the time of donation (four of them with a cycle threshold value <30). All recipients tested negative for SARS-CoV-2 and were free of coronavirus disease 2019 (COVID-19) symptoms prior to transplantation. Nasopharyngeal swab turned positive for SARS-CoV-2 PCR in 4 (5.8%) recipients at 3, 8, 11, and 20 days after transplantation, though evidence did not support a donor-derived COVID-19. Four kidney recipients lost their grafts and two patients died: one heart recipient due to cardiogenic shock and one combined liver-kidney recipient due to lung hypertension and right heart failure. Graft losses and patient deaths were deemed unrelated to the donor SARS-CoV-2 status by the treating teams. No other adverse reactions were reported. CONCLUSIONS: This preliminary experience supports the safety of the use of organs other than lungs from SARS-CoV-2 PCR-positive donors, in alignment with previous series. However, the impact of SARS-CoV-2 infection upon organ quality should be established in future research.

COVID-19 in transplant recipients: The Spanish experience

We report the nationwide experience with solid organ transplant (SOT) and hematopoietic stem cell transplant (HSCT) recipients diagnosed with coronavirus disease 2019 (COVID-19) in Spain until 13 July 2020. We compiled information for 778 (423 kidney, 113 HSCT, 110 liver, 69 heart, 54 lung, 8 pancreas, 1 multivisceral) recipients. Median age at diagnosis was 61 years (interquartile range [IQR]: 52-70), and 66% were male. The incidence of COVID-19 in SOT recipients was two-fold higher compared to the Spanish general population. The median interval from transplantation was 59 months (IQR: 18-131). Infection was hospital-acquired in 13% of cases. No donor-derived COVID-19 was suspected. Most patients (89%) were admitted to the hospital. Therapies included hydroxychloroquine (84%), azithromycin (53%), protease inhibitors (37%), and interferon-β (5%), whereas immunomodulation was based on corticosteroids (41%) and tocilizumab (21%). Adjustment of immunosuppression was performed in 85% of patients. At the time of analysis, complete follow-up was available from 652 patients. Acute respiratory distress syndrome occurred in 35% of patients. Ultimately, 174 (27%) patients died. In univariate analysis, risk factors for death were lung transplantation (odds ratio [OR]: 2.5;95% CI: 1.4-4.6), age >60 years (OR: 3.7;95% CI: 2.5-5.5), and hospital-acquired COVID-19 (OR: 3.0;95% CI: 1.9-4.9).

COVID-19 pandemic and worldwide organ transplantation: a population-based study.

BACKGROUND: Preliminary data suggest that COVID-19 has reduced access to solid organ transplantation. However, the global consequences of the COVID-19 pandemic on transplantation rates and the effect on waitlisted patients have not been reported. We aimed to assess the effect of the COVID-19 pandemic on transplantation and investigate if the pandemic was associated with heterogeneous adaptation in terms of organ transplantation, with ensuing consequences for waitlisted patients. METHODS: In this population-based, observational, before-and-after study, we collected and validated nationwide cohorts of consecutive kidney, liver, lung, and heart transplants from 22 countries. Data were collected from Jan 1 to Dec 31, 2020, along with data from the same period in 2019. The analysis was done from the onset of the 100th cumulative COVID-19 case through to Dec 31, 2020. We assessed the effect of the pandemic on the worldwide organ transplantation rate and the disparity in transplant numbers within each country. We estimated the number of waitlisted patient life-years lost due to the negative effects of the pandemic. The study is registered with ClinicalTrials.gov, NCT04416256. FINDINGS: Transplant activity in all countries studied showed an overall decrease during the pandemic. Kidney transplantation was the most affected, followed by lung, liver, and heart. We identified three organ transplant rate patterns, as follows: countries with a sharp decrease in transplantation rate with a low COVID-19-related death rate; countries with a moderate decrease in transplantation rate with a moderate COVID-19-related death rate; and countries with a slight decrease in transplantation rate despite a high COVID-19-related death rate. Temporal trends revealed a marked worldwide reduction in transplant activity during the first 3 months of the pandemic, with losses stabilising after June, 2020, but decreasing again from October to December, 2020. The overall reduction in transplants during the observation time period translated to 48 239 waitlisted patient life-years lost. INTERPRETATION: We quantified the impact of the COVID-19 pandemic on worldwide organ transplantation activity and revealed heterogeneous adaptation in terms of organ transplantation, both at national levels and within countries, with detrimental consequences for waitlisted patients. Understanding how different countries and health-care systems responded to COVID-19-related challenges could facilitate improved pandemic preparedness, notably, how to safely maintain transplant programmes, both with immediate and non-immediate life-saving potential, to prevent loss of patient life-years.

Organ donation and transplantation: a multi-stakeholder call to action.

Although overall donation and transplantation activity is higher in Europe than on other continents, differences between European countries in almost every aspect of transplantation activity (for example, in the number of transplantations, the number of people with a functioning graft, in rates of living versus deceased donation, and in the use of expanded criteria donors) suggest that there is ample room for improvement. Herein we review the policy and clinical measures that should be considered to increase access to transplantation and improve post-transplantation outcomes. This Roadmap, generated by a group of major European stakeholders collaborating within a Thematic Network, presents an outline of the challenges to increasing transplantation rates and proposes 12 key areas along with specific measures that should be considered to promote transplantation. This framework can be adopted by countries and institutions that are interested in advancing transplantation, both within and outside the European Union. Within this framework, a priority ranking of initiatives is suggested that could serve as the basis for a new European Union Action Plan on Organ Donation and Transplantation.

COVID-19 in Solid Organ Transplant Recipients in Spain Throughout 2020: Catching the Wave?

BACKGROUND: Few studies have analyzed differences in clinical presentation and outcomes in solid organ transplant (SOT) recipients with coronavirus disease 2019 (COVID-19) across different pandemic waves. METHODS: In this multicenter, nationwide, prospective study, we compared demographics and clinical features, therapeutic management, and outcomes in SOT recipients diagnosed with COVID-19 in Spain before (first wave) or after (second wave) 13 July 2020. RESULTS: Of 1634 SOT recipients, 690 (42.2%) and 944 (57.8%) were diagnosed during the first and second periods, respectively. Compared with the first wave, recipients in the second were younger (median: 63 y [interquartile range, IQR: 53-71] versus 59 y [IQR: 49-68]; P < 0.001) and less likely to receive anti-severe acute respiratory syndrome coronavirus 2 drugs (81.8% versus 8.1%; P < 0.001), with no differences in immunomodulatory therapies (46.8% versus 47.0%; P = 0.931). Adjustment of immunosuppression was less common during the second period (76.4% versus 53.6%; P < 0.001). Hospital admission (86.7% versus 58.1%; P < 0.001), occurrence of acute respiratory distress syndrome (34.1% versus 21.0%; P < 0.001), and case-fatality rate (25.8% versus 16.7%; P < 0.001) were lower in the second period. In multivariate analysis, acquiring COVID-19 during the first wave was associated with an increased risk of death (OR: 1.47; 95% confidence interval [CI], 1.12-1.93; P = 0.005), although this impact was lost in the subgroup of patients requiring hospital (OR: 0.97; 95% CI, 0.73-1.29; P = 0.873) or intensive care unit admission (OR: 0.65; 95% CI, 0.35-1.18; P = 0.157). CONCLUSIONS: We observed meaningful changes in demographics, therapeutic approaches, level of care, and outcomes between the first and second pandemic waves. However, outcomes have not improved in the more severe cases of posttransplant COVID-19.

Trasplante renal en época COVID-19 en España

INTRODUCCIÓN: La epidemia de COVID-19 plantea importantes retos en el ámbito de la donación y el trasplante renal. El objetivo de este artículo es establecer unas recomendaciones generales dirigidas a los equipos quirúrgicos de trasplante renal durante la era COVID-19. MATERIAL Y MÉTODOS: El documento se basa en la evidencia científica disponible sobre la infección causada por SARS-CoV-2 y la experiencia de los autores en la pandemia COVID-19. Se realizó una búsqueda web y en PubMed utilizando las palabras clave "SARSCoV-2", "COVID-19", "COVID rology", "COVID-19 surgery"y "kidney transplantation". Se ha utilizado una técnica de grupo nominal modificada. RESULTADOS: En momentos de saturación del sistema sanitario, se deberán diferir los trasplantes renales, salvo en pacientes con bajas posibilidades de trasplante y un riñón óptimo disponible, trasplantes combinados o pacientes en situación de urgencia vital. Se deberá hacer cribado del virus SARS-CoV-2 en todos aquellos donantes y receptores que tengan sospecha clínica, hayan estado en zonas de alto riesgo o hayan compartido proximidad con casos confirmados de COVID-19. Nos e procederá con la donación ni con el trasplante en casos confirmados de COVID-19. Las cirugías deberáns er eficientes, cortas y centradas en las que menor estancia hospitalaria conlleven. En casos de urgencia, se extremarán las medidas de protección con equipos de protección individual. El personal quirúrgico será el menor posible y se minimizarán las estancias en quirófano. Las consultas urológicas de trasplante sin riesgo serán realizadas telemáticamente cuando sea posible. CONCLUSIÓN: La cirugía de trasplante renal debe ser eficiente en cuanto a recursos sanitarios, humano sy beneficio clínico. Se debe garantizar la seguridad de los potenciales donantes y receptores, adoptando medidas de protección individual y realizando cribado para SARS-CoV-2 INTRODUCTION: The COVID-19 pandemic poses significant challenges in the area of kidney donation and transplantation. The objective of this article is to establish general recommendations for surgical teams to manage the kidney transplant program during the COVID-19 era. MATERIAL AND METHODS: This document is based on the scientific evidence available on the infection caused by SARS-CoV-2 and the experience of authors during the COVID-19 pandemic. A web and Pubmed search was performed using the keywords "SARS-CoV-2", "COVID-19", "COVID Urology", "COVID-19 surgery", and "kidney transplantation."A modified nominal group technique was used. RESULTS: When health system saturation occurs, kidney transplants should be deferred, except in patients with low transplant possibilities and an optimal kidney available, combined transplants or life-threatening situations. Screening for the SARS-CoV-2 virus should be done in all those donors and recipients with clinical symptoms consistent with COVID-19, who have visited or live in high-risk areas, or who have been in close contact with confirmed cases of COVID-19. Donation and transplantation will not proceed in confirmed cases of COVID-19. Surgeries should be based on general recommendations in the COVID-19 era and will be efficient, short, and focused on those with the shortest hospital stay. In emergencies, protective measures will be taken with personal protection equipment. Surgical staff will be only the strictly necessary, and permanence in the OR should be minimized. Transplant urology consultations will be conducted by teleconsultation when possible. CONCLUSION: The safety of potential donors and recipients must be guaranteed, adopting individual protection measures and screening for SARS-CoV-2. Kidney transplant surgery must be efficient in terms of health, human resources, and clinical benefit. All non-urgent transplant activities should be delayed until the improvement of the local condition of each center

Organ Donation and Transplantation During the COVID-19 Pandemic: A Summary of the Spanish Experience.

BACKGROUND: Spain has been amongst the countries most affected by the COVID-19 pandemic, which has posed significant challenges to the donation and transplantation program. Despite a dramatic decrease of donation and transplantation activities during the critical early weeks of the outbreak, the program has recovered and is learning to cope with COVID-19. METHODS: We describe the 4 pillars upon which the Spanish donation and transplantation program has been rebuilt. RESULTS: (1) Standards have been developed and progressively updated for the evaluation and selection of potential donors and recipients with regards to SARS-CoV-2 infection. (2) Spain has been actively generating evidence to assess the validity of our standards and to understand the natural history of the infection in transplant recipients. No case of donor-derived COVID-19 has been reported to date. COVID-19 has been more frequent and has had a more aggressive course in recipients of solid organ transplants than in the general population, but this seems largely explained by the demographics and comorbidity of transplant patients. (3) As a result of this evidence and experience, recommendations have been issued for the management of COVID-19 in solid organ transplant recipients and candidates on the waiting list. (4) Finally, concrete guidance has been issued for centers to manage the donation and transplantation programs in relation to a dynamic and heterogeneous epidemiologic scenario. CONCLUSIONS: The Spanish experience confronting the impact of COVID-19 upon donation and transplantation may help serve the needs of a broader community in other countries.

We compiled information for 778 (423 kidney, 113 HSCT, 110 liver, 69 heart, 54 lung, 8 pancreas, 1 multivisceral) recipients. Median age at diagnosis was 61 years (interquartile range [IQR]: 52-70), and 66% were male. The incidence of COVID-19 in SOT recipients was two-fold higher compared to the Spanish general population.

Online education about end-of-life care and the donation process after brain death and circulatory death. Can we influence perception and attitudes in critical care doctors? A prospective study.

Impact of training on end-of-life care (EOLC) and the deceased donation process in critical care physicians' perceptions and attitudes was analysed. A survey on attitudes and perceptions of deceased donation as part of the EOLC process was delivered to 535 physicians working in critical care before and after completion of a online training programme (2015-17). After training, more participants agreed that nursing staff should be involved in the end-of-life decision process (P < 0.001) and that relatives should not be responsible for medical decisions (P < 0.001). Postcourse, more participants considered 'withdrawal/withholding' as similar actions (P < 0.001); deemed appropriate the use of pre-emptive sedation in all patients undergoing life support treatment adequacy (LSTA; P < 0.001); and were favourable to approaching family about donation upon LSTA agreement, as well as admitting them in the intensive care unit (P < 0.001) to allow the possibility of donation. Education increased the number of participants prone to initiate measures to preserve the organs for donation before the declaration of death in patients undergoing LSTA (P < 0.001). Training increased number of positive terms selected by participants to describe donation after brain and circulatory death. Training programmes may be useful to improve physicians' perception and attitude about including donation as part of the patient's EOLC.

COVID-19 in Spain: Transplantation in the midst of the pandemic.

Spain has been one of the most affected countries by the COVID-19 outbreak. As of April 28, 2020, the number of confirmed cases is 210 773, including 102 548 patients recovered, more than 10 300 admitted to the ICU, and 23 822 deaths, with a global case fatality rate of 11.3%. From the perspective of donation and transplantation, the Spanish system first focused on safety issues, providing recommendations for donor evaluation and testing, and to rule out SARS-CoV-2 infection in potential recipients prior to transplantation. Since the country entered into an epidemiological scenario of sustained community transmission and saturation of intensive care, developing donation and transplantation procedures has become highly complex. Since the national state of alarm was declared in Spain on March 13, 2020, the mean number of donors has declined from 7.2 to 1.2 per day, and the mean number of transplants from 16.1 to 2.1 per day. Increased mortality on the waiting list may become a collateral damage of this terrible pandemic.
