ABSTRACT
A 66-year-old male with end-stage liver disease (ESLD) secondary to non-alcoholic fatty liver disease (NAFLD), complicated by hepatocellular carcinoma (HCC), underwent deceased donor liver transplantation from a Coronavirus disease 2019 (COVID-19) positive donor. He presented a month later with fever, diarrhea and pancytopenia which led to hospitalization. The hospital course was notable for respiratory failure, attributed to invasive aspergillosis, as well as a diffuse rash. A bone marrow biopsy revealed hypocellular marrow without specific findings. In the following days, laboratory parameters raised concern for secondary hemophagocytic lymphohistiocytosis (HLH). Clinical concern also grew for solid organ transplant graft-versus-host-disease (SOT-GVHD) based on repeat marrow biopsy with elevated donor-derived CD3+ T cells on chimerism. After, a multidisciplinary discussion, the patient was started on ruxolitinib, in addition to high dose steroids, to address both SOT-GVHD and secondary HLH. Patient developed symptoms concerning for hemorrhagic stroke and was transitioned to comfort care. Although GVHD has been studied extensively in hematopoietic stem cell transplant (HSCT) patients, it is a rare entity in SOT with a lack of guidelines for management. Additionally, whether COVID-19 may play a role in development of SOT-GVDH has not been explored.
ABSTRACT
Waitlist time for kidney transplantation is long but may be shortened with the utilization of hepatitis C positive allografts. We retrospectively reviewed the course of 36 hepatitis C positive patients awaiting kidney transplantation at 2 large centers within the same health system, with near-identical care delivery models with the exception of timing of hepatitis C treatment, to determine the impact of timing of hepatitis C treatment on access to transplant, waitlist time, and treatment efficacy and tolerability. The majority of patients had hepatitis C genotype 1a or 1b, and all received direct acting antiviral therapy with 100% treatment response. One patient underwent transplantation in the pretransplant treatment group. The 1-year transplantation rate was 12.5% vs 67.9% (P = .0013) in those treated posttransplantation. The median waitlist time in the posttransplant group was 122 (interquartile range [IQR] 21.5, 531.0) days, which was significantly shorter than the center's regional and national wait time. Pathologic review revealed no difference in allograft quality. Overall treatment related adverse events were not different between the 2 groups. A strategy of posttransplant hepatitis C treatment increased access to transplant and reduced waitlist time. Delaying treatment until after transplant did not appear to adversely affect recipients' kidney allograft or overall survival.
