NCT ID: NCT05995379 Completed - Clinical trials for Kidney Rejection Transplant

Donor Derived Cell-free DNA and Rejection of Kidney Allografts

Start date: September 21, 2011
Phase:
Study type: Observational

To assess the association of dd-cfDNA with the presence, activity and severity of allograft rejection, and determine whether dd-cfDNA adds value to standard of care monitoring parameters in detecting kidney allograft rejection.

NCT ID: NCT05811468 Recruiting - Kidney Transplant Clinical Trials

Study Correlation Between Blood, Tissue Gene Expression, Donor Derived Cell Free DNA and Histopathology in Kidney Transplant Recipients

Start date: September 26, 2023
Phase:
Study type: Observational

This study will compare the performance of Gene Expression Profile (GEP)/ Donor derived cell free deoxyribonucleic acid (dd-cfDNA) tests, to the following tests: Molecular Microscope (MMDx) and histopathology (study of changes in tissues caused by disease) in their ability to diagnose (exactly identify) various types of injury within the transplanted kidney.

NCT ID: NCT05061303 Active, not recruiting - Clinical trials for Kidney Rejection Transplant

Omeprazole and Famotidine in Chronic Dysfunction of the Transplanted Kidney

Start date: October 17, 2021
Phase:
Study type: Observational [Patient Registry]

The aim of the study is to compare the effect of omeprazole and famotidine on the risk of developing chronic renal transplant dysfunction. For the study, it is planned to qualify 24 stabilized adult patients from 1-24 months after kidney transplantation, who will receive p.o. the standard, most commonly used triple immunosuppression regimen: tacrolimus, mycophenolate mofetil, prednisone and depending on the group p.o.: omeprazole 20 mg (group I) or famotidine 20 mg (group II). The material in the study will be blood, in which tacrolimus concentrations will be measured at the following time points: 0, 2h, 6h, 12h after drug administration, without taking omeprazole/famotidine and then the next day after taking the protective drug in same time points, without 12h. Sequentially routinely in the so-called point T0 before taking the drug (12 hours after the last dose) during follow-up visits at the Transplant Outpatient Clinic. Tacrolimus concentrations will be determined using the Chemiluminescent Microparticle Immuno Assay method. As standard, laboratory tests will be performed during follow-up visits. In addition, it is planned to assess titer of donor-specific antibodies at the time of qualification and then after 18 months, immunological profile (flow cytometry) at the time of qualification and then after 18 months, and concentration in serum and urine of a potential marker of progression and decrease in glomerular filtration - kidney injury molecule-1 at the time of qualification and then after 18 months. The obtained results will be correlated with the histopathological evaluation of the transplanted kidney in the case of organ biopsy performed on clinical indications. Comparative statistical analysis of drug concentration values will be carried out. Additionally, genetic tests will be performed to assess the patient's metabolic variant for CYP2C19. Due to the potential influence of omeprazole on the pharmacokinetics of tacrolimus, which may influence the process of chronic rejection of the transplanted kidney and drug toxicity, it seems important to study this hypothesis, as well as researching for therapeutic substances neutral to the above process. The use of famotidine in place of omeprazole may turn out more beneficial and safer for renal transplant patients. During follow-up visits at the Transplant Clinic at the Department and Clinic of Nephrology, Transplantology and Internal Diseases, changes in blood concentrations of tacrolimus are noticed. Related reasons are being looked for. The above study will confirm or reject the relationship of changes in tacrolimus levels with omeprazole. It is planned to present the results at a scientific conference. The research results will be published in a scientific journal.

NCT ID: NCT04078750 Recruiting - Clinical trials for Medication Adherence

PLATO - Medication Adherence in Transplant Recipients

Start date: September 10, 2019
Phase: N/A
Study type: Interventional

Non-adherence with immunosuppressant drugs is a major reason for premature kidney transplant failure. Currently, patient education and compliance aids (e.g bubble packing) are commonly used to assist patients. This is a study involving patients expected to undergo a kidney transplant within 6 months. One group will undergo a one-month formal assessment of adherence before transplantation using mock immunosuppressant medication. Standardized surveys will also be administered to assess risk factors for non-adherence. A plan will be developed for use after the transplant. The other group will undergo usual care. Kidney function and rejection rates will be compared between two groups.
