Objective: The main goal of this doctoral thesis was to investigatethe association between the parameters of pharmacokinetic variabilityof tacrolimus (Tac), polymorphisms in interleukin (IL) genes andmicroRNA expression levels with graft function in the long-termperiod after kidney transplantation. Patients and Methods: The studyincluded 115 kidney transplant recipients on Tac-basedimmunosuppression and 91 healthy controls. The thesis wasconducted as a prospective study and a cross-sectional study.Tacrolimus daily dose and trough concentration in whole blood (C0)were recorded over a five-year post-transplantation period. The doseadjustedC0 (C0/D) and intraindividual pharmacokinetic variability(IPV) of Tac were calculated. Graft function was assessed usingestimated glomerular filtration rate, while adverse outcomes in thelong-term post-transplantation period were recorded (graft failure,chronic dysfunction and rejection, and doubling of serum creatinineconcentration). Genetic polymorphisms -174G/C in the IL-6 gene, -1082G/A, -819C/T, and -592C/A in the IL-10 gene, -607A/C and -137G/C in the IL-18 gene were detected using appropriate PCRmethods. Plasma concentrations of IL-6, IL-10, IL-18, and cystatin Cwere measured, as well as the urinary expression of miR-21-5p, miR-142-3p, miR-155-5p, and miR-204-5p in patients and controls.Results: The findings of this study demonstrated that patientsexhibiting both lower Tac C0/D and higher Tac IPV values hadapproximately a 3-fold increased risk of developing adverse outcomesduring the five-year post-transplantation follow-up. Furthermore,gene polymorphisms IL-6 -174G/C, IL-10 -1082G/A, and IL-18 -137G/C, the Tac metabolic phenotype determined based on Tac C0/Dat the 3rd post-transplantation month, and the post-transplantationperiod were independent predictors of Tac C0/D from months 6 to 60.The study also showed a significant dysregulation of miR-204-5p inthe urine of kidney transplant patients in the long-term period,demonstrating its correlation with Tac metabolic phenotype and graftfunction in the late post-transplantation period. Conclusion: Theresults of the doctoral dissertation may contribute to the improvementof post-transplantation outcomes, while also serving as a foundationfor further research.
