COVID19 convalescent patient plasma units with high titer neutralizing antibody can be used to treat patients with severe disease. Therefore, in order to select suitable donors, neutralizing antibody titer against SARS CoV-2 needs to be determined. Because the neutralization assay is highly demanding from several points of view, a pre-selection of sera would be desirable to minimize the number of sera to be tested.

Tacrolimus (TAC) is a widely used immunosuppressant with a narrow therapeutic index and potential severe side effects, including neurotoxicity and kidney injury. We herein report a case of 60-year-old woman who underwent deceased-donor liver transplantation at our center and due to inadvertent TAC overexposure was admitted to the Intensive Care Unit because of severe neurologic impairment, kidney injury and arterial hypotension.

From January to December 2006, all liver transplantation (LT) recipients at risk of renal or neurological complications treated with extracorporeal photopheresis (ECP) + mycophenolate mofetil + steroids and staggered introduction of CI (ECP group) were compared with a historical control group on standard CI-based immunosuppression. The ECP group included 24 patients with a mean model for end-stage liver disease (MELD) score of 19.

The aim of the current report is to illustrate the results of a retrospective comparison study on the use of immunomodulation with therapeutic plasma exchange (TPE) associated to high-dose immunoglobulins (IVIg) and extracorporeal photopheresis (ECP) in ABO-i adult LT patients.
Patients And Methods: Between January 1996 and December 2005, 19 patients underwent ABO-i LT.
