BACKGROUND:

Since phase III trials for the most prominent vaccines excluded immunocompromised or immunosuppressed patients, data on safety and efficacy of SARS-CoV-2 vaccines for recipients of solid organ transplantations are scarce.

AIMS:

Our study offers a synthesis of expert opinions aligned with available data addressing key questions of the clinical management of SARS-CoV-2 vaccinations for transplant patients.

METHOD:

An online research was performed retrieving available recommendations by national and international transplantation organizations and state institutions on SARS-CoV2 vaccination management for transplant recipients.

RESULTS:

Eleven key statements were identified from recommendations by 18 national and international societies, and consensus for the individual statements was evaluated by means of the Society Recommendation Consensus score. The highest consensus level (SRC A) was found for prioritized access to vaccination for transplant patients despite anticipation of a weakened immune response. All currently authorized vaccines can be considered safe for transplant patients (SRC A). The handling of immunosuppressive medication, the timely management of vaccines, and other aspects were aligned with available expert opinions.

CONCLUSION:

Expert consensus can be determined for crucial aspects of the implementation of SARS-CoV-2 vaccination programs. We hereby offer a tool for immediate decision-making until empirical data becomes available.

BACKGROUND:

The current SARS-CoV-2 pandemic may negatively impact the care of liver transplant candidates and recipients.

MAIN BODY OF THE ABSTRACT:

Accordingly, each country must have its national guidelines based on the current situation and according to available tools. Liver Transplantation Scientific Committee of Waiting List Project in Egypt was established in 13 April 2020. One of the major objectives of this Scientific Committee is the preparation of national protocol for Transplant Centers in Egypt to deal with living donor liver transplantation (LDLT) during SARS-CoV-2 pandemic.

CONCLUSIONS:

The protocol highlights basic hospital requirements for LDLT during SARS-CoV-2 pandemic, the patient selection from the waiting list, management of patients on the waiting list, and post-transplant management.

In December 2019, novel coronavirus (SARS-CoV-2) infection started in Wuhan and resulted in a pandemic within a few weeks' time. Organ transplant recipients being at a risk for more severe COVID-19 if they get SARS CoV-2 viral infection, COVID-19 vaccine has a significant role in these patients. The vaccine is a safer way to help build protection and would either prevent COVID-19 infection or at least diminish the severity of the disease. It would also reduce the risk of the continuing transmission and enhance herd immunity. Immuno-compromised patients should not receive live vaccines as they can cause vaccine-related disease and hence the guidelines suggest that all transplant recipients should receive age-appropriate 'inactivated vaccine' as recommended for general population. Though trials have not been undertaken on transplant recipients, efficacy and safety of COVID-19 vaccine have been scientifically documented for few vaccines among the general population.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the least deadly but most infectious coronavirus strain transmitted from wild animals. It may affect many organ systems. Aim of the current guideline is to delineate the effects of SARS-CoV-2 on the liver. Asymptomatic aminotransferase elevations are common in coronavirus disease 2019 (COVID-19) disease. Its pathogenesis may be multifactorial. It may involve primary liver injury and indirect effects such as "bystander hepatitis," myositis, toxic liver injury, hypoxia, and preexisting liver disease. Higher aminotransferase elevations, lower albumin, and platelets have been reported in severe compared with mild COVID-19. Despite the dominance of respiratory disease, acute on chronic liver disease/acute hepatic decompensation have been reported in patients with COVID-19 and preexisting liver disease, in particular cirrhosis. Metabolic dysfunction-associated fatty liver disease (MAFLD) has a higher risk of respiratory disease progression than those without MAFLD. Alcohol-associated liver disease may be severely affected by COVID-19-such patients frequently have comorbidities including metabolic syndrome and smoking-induced chronic lung disease. World Gastroenterology Organization (WGO) recommends that interventional procedures such as endoscopy and endoscopic retrograde cholangiopancreatography should be performed in emergency cases or when they are considered strictly necessary such as high risk varices or cholangitis. Hepatocellular cancer surveillance may be postponed by 2 to 3 months. A short delay in treatment initiation and non-surgical approaches should be considered. Liver transplantation should be restricted to patients with high MELD scores, acute liver failure and hepatocellular cancer within Milan criteria. Donors and recipients should be tested for SARS-CoV-2 and if found positive donors should be excluded and liver transplantation postponed until recovery from infection.

BACKGROUND:

The COVID-19 pandemic has disrupted all aspects of the international organ donation and transplantation (ODT) system. Multiple organizations have developed guidance, but to date, no comparative summary has emerged to understand differences in existing recommendations.

METHODS:

We developed and applied a comparative methodology to a convenience sample of recommendations available on The Transplantation Society website. Document types were classified according to characteristics such as type of organization (eg, governing body or professional society) and geographic region. Recommendations were grouped according to content, and summaries were posted on a public website. This process is ongoing and will be updated as new recommendations become available.

RESULTS:

Eighteen documents were extracted in the initial review. All documents were based on expert opinion, and none described a formal literature review or adherence with clinical guideline development processes. Recommendation categories included screening of potential donors, risk assessment of potential recipients, posttransplant risk, living/paired donation, protection of ODT professionals, and ethics/logistics. While many documents included similar recommendations, such as the need to screen and test patients who are potential donors, there was variation on some topics. Type of recommended laboratory testing varied with 64% recommending nasopharyngeal swabs, 43% oropharyngeal, and 24% bronchial aspirates. Updated results are available at https://cdtrp.ca/en/covid-19-international-recommendations-for-odt/.

CONCLUSIONS:

The current state of COVID-19 ODT recommendations is limited to expert opinion. Substantial variation exists regarding recommendations, which are based on emerging but currently low-quality evidence. This summary of existing recommendations will serve to inform priorities for evidence-based recommendations.

In this paper, we aim to provide professional guidance to clinicians who are managing patients with chronic liver disease during the current coronavirus disease 2019 (COVID-19) pandemic in Singapore. We reviewed and summarised the available relevant published data on liver disease in COVID-19 and the advisory statements that were issued by major professional bodies, such as the American Association for the Study of Liver Diseases and European Association for the Study of the Liver, contextualising the recommendations to our local situation.

The coronavirus disease 2019 (COVID-19) pandemic has created many challenges for pediatric solid organ transplant (SOT) recipients and their families. As the pandemic persists, patients and their families struggle to identify the best and safest practices for resuming activities as areas reopen. Notably, decisions about returning to school remain difficult. We assembled a team of pediatric infectious diseases (ID), transplant ID, public health, transplant psychology, and infection prevention and control specialists to address the primary concerns about school reentry for pediatric SOT recipients in the United States. Based on available literature and guidance from national organizations, we generated consensus statements pertaining to school reentry specific to pediatric SOT recipients. Although data are limited and the COVID-19 pandemic is highly dynamic, our goal was to create a framework from which providers and caregivers can identify the most important considerations for each pediatric SOT recipient to promote a safe return to school.
