Analysis of ABCB1 Gene Polymorphisms and Their Impact on Tacrolimus Blood Levels in Kidney Transplant Recipients.

Tacrolimus (Tc) is an immunosuppressant used in transplant patients, but its therapeutic range is narrow, making precise dosing essential. This study investigates the association of three single nucleotide polymorphisms (SNPs) (ABCB1 3435C>T, 1236C>T, 2677G>T/A) with Tc levels over time to gain better insights into their role in personalized medicine. We conducted the study over four distinct periods: 1-14 days, 15-30 days, 31-60 days, and beyond 60 days post-transplantation.

Single Nucleotide Polymorphisms of CYP3A4 and CYP3A5 in Romanian Kidney Transplant Recipients: Effect on Tacrolimus Pharmacokinetics in a Single-Center Experience.

: This study examines the impact of CYP3A4 and CYP 3A5 genotypes on tacrolimus (Tac) pharmacokinetics in Romanian kidney transplanted patients. We included 112 kidney recipients genotyped for CYP3A5*3, CYP3A4*1.001, and CYP3A4*22.

Immunogenetic Background of Chronic Lymphoproliferative Disorders in Romanian Patients-Case Control Study.

Background And Objectives: The implications of the genetic component in the initiation and development of chronic lymphoproliferative disorders have been the subject of intense research efforts. Some of the most important genes involved in the occurrence and evolution of these pathologies are the HLA genes. The aim of this study is to analyze, for the first time, possible associations between chronic lymphoproliferative diseases and certain HLA alleles in the Romanian population.

Retrospective Study from a Single Center in Romania of 347 Renal Transplant Patients Treated with Tacrolimus, Mycophenolate, and Steroids to Evaluate the Association Between Anti-HLA Antibodies and 5-Year Graft Survival.

BACKGROUND Kidney transplantation is the most recommended treatment in chronic kidney disease. The recipient's immune system reacts to a kidney graft as to an alloantigen by producing antibodies (anti-human leukocyte antigens [HLAs]). Although immunosuppressive therapy is used to overcome this problem, the long-term survival of a kidney graft after 5 years remains low.
