BACKGROUND: Early in the coronavirus disease 2019 (COVID-19) pandemic, there was a significant impact on routine medical care in the United States, including in fields of transplantation and oncology. AIM: To analyze the impact and outcomes of early COVID-19 pandemic on liver transplantation (LT) for hepatocellular carcinoma (HCC) in the United States. METHODS: WHO declared COVID-19 as a pandemic on March 11, 2020. We retrospectively analyzed data from the United Network for Organ Sharing (UNOS) database regarding adult LT with confirmed HCC on explant in 2019 and 2020. We defined pre-COVID period from March 11 to September 11, 2019, and early-COVID period as from March 11 to September 11, 2020. RESULTS: Overall, 23.5% fewer LT for HCC were performed during the COVID period (518 vs 675, P < 0.05). This decrease was most pronounced in the months of March-April 2020 with a rebound in numbers seen from May-July 2020. Among LT recipients for HCC, concurrent diagnosis of non-alcoholic steatohepatitis significantly increased (23 vs 16%) and alcoholic liver disease (ALD) significantly decreased (18 vs 22%) during the COVID period. Recipient age, gender, BMI, and MELD score were statistically similar between two groups, while waiting list time decreased during the COVID period (279 days vs 300 days, P = 0.041). Among pathological characteristics of HCC, vascular invasion was more prominent during COVID period (P < 0.01), while other features were the same. While the donor age and other characteristics remained same, the distance between donor and recipient hospitals was significantly increased (P < 0.01) and donor risk index was significantly higher (1.68 vs 1.59, P < 0.01) during COVID period. Among outcomes, 90-day overall and graft survival were the same, but 180-day overall and graft were significantly inferior during COVID period (94.7 vs 97.0%, P = 0.048). On multivariable Cox-hazard regression analysis, COVID period emerged as a significant risk factor of post-transplant mortality (Hazard ratio 1.85; 95%CI: 1.28-2.68, P = 0.001). CONCLUSION: During COVID period, there was a significant decrease in LTs performed for HCC. While early postoperative outcomes of LT for HCC were same, the overall and graft survival of LTs for HCC after 180 days were significantly inferior.

The coronavirus disease 2019 (COVID-19) pandemic created an unprecedented challenge for healthcare, and the world continues to struggle in recovering from its aftermath. COVID-19 has been clearly linked to hypercoagulable states and can lead to end-organ ischemia, morbidity, and mortality. Immunosuppressed solid organ transplant recipients represent a highly vulnerable population for the increased risk of complications and mortality. Early venous or arterial thrombosis with acute graft loss after whole pancreas transplantation is well-described, but late thrombosis is rare. We herein report a case of acute, late pancreas graft thrombosis at 13 years post pancreas-after-kidney (PAK) transplantation coinciding with an acute COVID-19 infection in a previously double-vaccinated recipient.
