Impact of Pharmacogenetics and Pharmacodynamics on Transplantation

چکیده
In solid organ transplantation, new approaches able to reflect individual responses are required to monitor immunosuppressive therapy and to improve its safety and efficacy. In the last few years, preliminary studies about the clinical impact of the measurement of new specific biomarkers of exposure (pharmacogenetic biomarkers) and the biological effects (pharmacodynamic biomarkers) of immunosuppressive drugs have been carried out. Pharmacogenetics, by the association between some polymorphisms and drug dose requirement, combined with pharmacokinetic drug monitoring allows therapeutic concentrations to be achieved a few days after transplantation. However, there is also a need for pharmacodynamic monitoring that may reflect the degree of immunosuppression achieved in each patient. This pharmacodynamic measurement is based on the analysis of specific biomarkers strongly related with the mechanism of action of every immunosuppressive agent, and shows its immunomodulatory effect on T-cell response. The present article reviews some pharmacogenetic and pharmacodynamic biomarkers that have been proposed in solid organ transplant monitoring.

The influence of pharmacogenetics and cofactors on clinical outcomes in kidney transplantation.
INTRODUCTION Immunosuppressive drugs have a narrow therapeutic range and large inter-individual response variability. This has prompted pharmacogenetic studies, mostly with regard to their dose-concentration relationships, but also about proteins involved in their pharmacodynamics. Some polymorphisms of genes involved in their disposition pathways were shown to affect their dose-concentration r...

New challenges and promises in solid organ transplantation pharmacogenetics: the genetic variability of proteins involved in the pharmacodynamics of immunosuppressive drugs.
Interindividual variability in immunosuppressive drug responses might be partly explained by genetic variants in proteins involved in the immune response or associated with IS pharmacodynamics. On a general basis, the pharmacogenetics of drug target proteins is less known and understood than that of proteins involved in drug disposition pathways. The aim of this review is to facilitate research...
متن کاملPersonalized busulfan and treosulfan conditioning for pediatric stem cell transplantation: the role of pharmacogenetics and pharmacokinetics.
Busulfan- and treosulfan-based conditionings are the cornerstone of pediatric allogeneic hematopoietic stem cell transplantation (HSCT). Although both drugs are alkylating agents, their mechanisms of action, pharmacokinetics (PK) and toxicity profiles are different. Experience with busulfan in pediatric HSCT is broad and the knowledge on the pharmacodynamics (PD), PK and, to a lesser extent, ph...
متن کاملClinical implementation of pharmacogenetics in kidney transplantation: calcineurin inhibitors in the starting blocks.
Pharmacogenetics has generated many expectations for its potential to individualize therapy proactively and improve medical care. However, despite the huge amount of reported genetic associations with either pharmacokinetics or pharmacodynamics of drugs, the translation into patient care is still slow. In fact, strong evidence for a substantial clinical benefit of pharmacogenetic testing is sti...
