Coronavirus disease 2019 is caused by severe acute respiratory syndrome coronavirus 2 and emerged in Wuhan, China. It affects millions of people all over the world and has caused the deaths of thousands of people. Mortality rates were higher in transplant recipients and patients awaiting transplantation due to social and psychological issues. It also affected candidates who would be transplant providers and caused the transplant chain to be broken worldwide. The coronavirus disease 2019 pandemic has significantly affected solid organ transplantation procedures and led to various changes in protocols and practices to ensure patient safety and increase transplant success. These include challenges in screening protocols, prioritization of cases, telemedicine and virtual consultations, modified surgical procedures, immunosuppression management, updated research and guidelines, post-transplantation process and difficulties to control side effects, difficulties in organ procurement, and patient education/support. It requires a multidisciplinary approach, close collaboration between transplant teams, and adherence to strict infection control measures to ensure the safety of both transplant recipients and healthcare providers. In this article, we compiled the most important points in an overview of this process.

Towards the end of 2019, a new type of coronavirus, severe acute respiratory syndrome, emerged in the city of Wuhan in China's Hubei Province. The first occurrence was described as a case of pneumonia. Coronavirus disease 2019 (COVID-19) can progress primarily with symptoms varying from a mild upper respiratory tract infection to severe pneumonia, acute respiratory distress syndrome, and death. Determining the mechanisms of action of this virus, which can affect all systems including gastrointestinal, is vital for predicting the progression of the disease and managing its treatment. It is important to demonstrate the mechanisms of action of COVID-19 in patients without a previously known chronic or systemic disease. Although there is still no specific treatment for the virus, various algorithms have been created. As a result of the applied algorithms, the response to the treatment was satisfactory in some patients, while unexpected side effects occurred in some patients. It helps to clarify whether the unwanted effects that occur are due to the effect of the disease or the side effects of the drugs used in the treatment. There is currently increasing interest in COVID-19 interaction with liver tissue. Therefore, we would like to discuss the details of liver injury/dysfunction in the current literature.

Coronavirus disease-2019 (COVID-19) has led to a temporary suspension of liver transplant activity across the world and the remodeling of care for patients on the waiting list and transplant recipients with the increasing use of remote consultations. Emerging evidence shows that patients with more advanced liver disease are at increased risk of severe COVID-19 and death, whereas transplant recipients have similar risk with the general population which is mainly driven by age and metabolic comorbidities. Tacrolimus immunosuppression might have a protective role in the post-transplant population. Vaccines that have become rapidly available seem to be safe in liver patients, but the antibody response in transplant patients is likely suboptimal. Most transplant centers were gradually able to resume activity soon after the onset of the pandemic and after modifying their pathways to optimize safety for patients and workforce. Preliminary evidence regarding utilizing grafts from positive donors and/or transplanting recently recovered or infected recipients under certain circumstances is encouraging and may allow offering life-saving transplant to patients at the greatest need. This review summarizes the currently available data on liver transplantation in the context of a major pandemic and discusses areas of uncertainty and future challenges. Lessons learnt from the COVID-19 pandemic might provide invaluable guidance for future pandemics.
