TL;DR: In this paper, the authors analyzed immunogenicity in 43 liver transplant recipients in a median of 15 days (IQR, 12-24) after receiving two doses of the mRNA-based SARS-CoV-2 vaccine BNT162b2 following the standard protocol, and compared these results to a control group consisting of 20 healthcare workers.

Patients with Liver Cirrhosis Show High Immunogenicity upon COVID-19 Vaccination but Develop Premature Deterioration of Antibody Titers
Katharina Willuweit,A Frey,Moritz Passenberg,Johannes Korth,Nissrin Saka,Olympia E. Anastasiou,Birte Möhlendick,Andreas Schütte,Hartmut Schmidt,Jassin Rashidi-Alavijeh +9 more
TL;DR: The data reveals a favorable initial outcome after vaccination with the COVID-19 vaccine BNT162b2 in cirrhotic patients but show a rapid deterioration of the antibody response after time, thereby giving a strong hint towards the importance of early booster immunization for this group of patients.
Implications of anaemia and response to anaemia treatment on outcomes in patients with cirrhosis
Jassin Rashidi-Alavijeh,Nargiz Nuruzade,A Frey,Eva-Maria Huessler,Anne Hörster,Amos Cornelius Zeller,Andreas Schütte,Hartmut Schmidt,Katharina Willuweit,Christian M. Lange +9 more
TL;DR: In this paper , the role of iron supplementation in patients with cirrhosis and its capability to improve prognosis was assessed in regression models, and the association with transplant-free survival was assessed.

Durability of Immune Response after Application of a Third Dose of SARS-CoV-2 Vaccination in Liver Transplant Recipients
Moritz Passenberg,Roxane Authorsen-Grudmann,A Frey,Johannes Korth,Jaqueline Zmudzinski,Olympia E. Anastasiou,Birte Möhlendick,Hartmut Schmidt,Jassin Rashidi-Alavijeh,Katharina Willuweit +9 more
TL;DR: In this article , the authors assessed antibody responses in a total of 300 liver transplant recipients and observed antibody titers for six months each after patients had received the second and the third doses of the vaccination, explicitly excluding all patients who had suffered from SARS-CoV-2 infection.
HLA class II donor specific antibodies are associated with graft cirrhosis after liver transplant independent of the mean fluorescence intensity level.
Katharina Willuweit,A Frey,Lisa Bieniek,Andreas Heinold,Matthias Büchter,Matthias Büchter,Peter A. Horn,Heiner Wedemeyer,Kerstin Herzer +8 more
TL;DR: Occurrence of HLA class II DSA after LT is associated with graft cirrhosis and may indicate a higher risk to develop graft damage independent on MFI and requires an individualized risk management.
