Summary

Modern immunosuppression is characterized by a combination of different immunosuppressants. As a result, the dose of the individual substances, and thus also their side effects can be reduced. Immunosuppression on the basis of low-dose calcineurin inhibitors (CNI) with comparatively low CNI target levels could therefore prevail. Despite all efforts to optimize the treatment regimen after liver transplantation from deceased donors, the amount of medication remains high throughout the postoperative course with CNIs being the main component of immunosuppressive treatment. The main substance used is Tacrolimus in combination with steroids and possibly Mycophenolic acid. Tacrolimus is considered a narrow therapeutic index drug requiring individual dose titration, to achieve a satisfactory balance between maximizing efficacy and minimizing dose-related toxicity. Furthermore, transplanted recipients have to remain to a very demanding medication regimen for a long time. The burden of pills required is associated with decreased adherence, and lack of adherence can lead to rejection and possibly graft loss. The aim of present study is to assess the tough levels and need of doses adaptation in de novo liver transplantation with Tacrolimus in the clinical routine, without any intervention in the treatment regimen.

Conditions

  • Liver Transplantation

Interventions

DRUG

Tacrolimus

Similar to the clinical routine, as soon as a patient is able to swallow and has a sufficient gastrointestinal activity, Tacrolimus-based immunosuppression using Prograf®, Advagraf® or Envarsus® will be started. Furthermore, calcineurin inhibitors-based immunosuppression will be used (initial dose based on the patients' body weight) with the goal of tough levels of 3-7 ng/mL in the first seven days after liver transplantion, depending on immune status and indication for transplantation. Further tough levels will be determined based on factors such as patients' history and indication for liver transplant.
