RESUMEN

Background : Since its declaration as a global pandemic on March11th 2020, COVID-19 has had a significant effect on solid-organ transplantation. Aim of this study was to analyze the impact of COVID-19 on Liver transplantation (LT) in United States. Methods : We retrospectively analyzed the United Network for Organ Sharing database regarding characteristics of donors, adult-LT recipients, and transplant outcomes during early-COVID period (March 11- September 11, 2020) and compared them to pre-COVID period (March 11 - September 11, 2019). Results : Overall, 4% fewer LTs were performed during early-COVID period (4107 vs 4277). Compared to pre-COVID period, transplants performed in early-COVID period were associated with: increase in alcoholic liver disease as most common primary diagnosis (1315 vs 1187, P< 0.01), higher MELD score in the recipients (25 vs 23, P<0.01), lower time on wait-list (52 vs 84 days, P<0.01), higher need for hemodialysis at transplant (9.4 vs 11.1%, P=0.012), longer distance from recipient hospital (131 vs 64 miles, P<0.01) and higher donor risk index (1.65 vs 1.55, P<0.01). Early-COVID period saw increase in rejection episodes before discharge (4.6 vs 3.4%, P=0.023) and lower 90-day graft/patient survival (92.2 vs 96.5 %, P<0.01;90.2 vs 95.1 %, P<0.01). In multivariable cox-regression analysis, early-COVID period was the independent risk factor for graft failure at 90-days post-transplant (HR 1.77, P<0.01). Conclusions : During early-COVID period in United States, overall LT decreased, alcoholic liver disease was primary diagnosis for LT, rate of rejection episodes before discharge was higher and 90-days post-transplant graft survival was lower.

RESUMEN

BACKGROUND: Coronavirus disease 2019 (COVID-19) has affected all facets of life and continues to cripple nations. COVID-19 has taken the lives of more than 2.1 million people worldwide, with a global mortality rate of 2.2%. Current COVID-19 treatment options include supportive respiratory care, parenteral corticosteroids, and remdesivir. Although COVID-19 is associated with increased risk of morbidity and mortality in patients with comorbidities, the vulnerability, clinical course, optimal management, and prognosis of COVID-19 infection in patients with organ transplants has not been well described in the literature. The treatment of COVID-19 differs based on the organ(s) transplanted. Preliminary data suggested that liver transplant patients with COVID-19 did not have higher mortality rates than untransplanted COVID-19 patients. Table 1 depicts a compiled list of current published data on COVID-19 liver transplant patients. Most of these studies included both recent and old liver transplant patients. No distinction was made for early liver transplant patients who contract COVID-19 within their posttransplant hospitalization course. This potential differentiation needs to be further explored. Here, we report 2 patients who underwent liver transplantation who acquired COVID-19 during their posttransplant recovery period in the hospital. CASE DESCRIPTIONS: Two patients who underwent liver transplant and contracted COVID-19 in the early posttransplant period and were treated with hydroxychloroquine, methylprednisolone, tocilizumab, and convalescent plasma. This article includes a description of their hospital course, including treatment and recovery. CONCLUSION: The management of post-liver transplant patients with COVID-19 infection is complicated. Strict exposure precaution practice after organ transplantation is highly recommended. Widespread vaccination will help with prevention, but there will continue to be patients who contract COVID-19. Therefore, continued research into appropriate treatments is still relevant and critical. A temporary dose reduction of immunosuppression and continued administration of low-dose methylprednisolone, remdesivir, monoclonal antibodies, and convalescent plasma might be helpful in the management and recovery of severe COVID-19 pneumonia in post-liver transplant patients. Future studies and experiences from posttransplant patients are warranted to better delineate the clinical features and optimal management of COVID-19 infection in liver transplant recipients.

RESUMEN

Transplantation in potential candidates who have recently recovered from COVID-19 is a challenge with uncertainties regarding the diagnosis, multi-organ systemic involvement, prolonged viral shedding in immunocompromised patients, and optimal immunosuppression. A 42 year male with alcoholic hepatitis underwent a successful deceased donor liver transplantation 71 days after the initial diagnosis of COVID-19. At the time of transplant, he was SARS-CoV-2 PCR negative for 24 days and had a MELD score of 33. His post-operative course was complicated by acute rejection which responded to intense immune-suppression using T-cell depletion and steroids. He was discharged with normal end-organ function and no evidence of any active infection including COVID-19. Prospective organ transplant recipients who have recovered from COVID-19 can be considered for transplantation after careful pre-transplant evaluation, donor selection, and individualized risk-benefit analysis.
