Renal & Cardiac Risk Factors of AKI After Liver Transplantation

Status Not yet recruiting

Clinical Trial Summary

Background: Liver transplantation (LT) is an extensive operation with various factors contributing to the development of acute kidney injury in the perioperative period. Early diagnosis of AKI can improve clinical outcomes in LT recipients. Renal resistive index is measured in renal arteries and high resistive values are associated with more adverse cardiovascular events and renal failure progression. Myocardial performance index reflects overall cardiac function rather than systolic or diastolic function alone. Aim of the study: to investigate whether combined doppler renal resistive index and myocardial performance index could predict early postoperative acute kidney injury in living donor liver transplant recipients. Study design: a prospective observational study that will be conducted at Liver Transplantation Unit at Mansoura University on 105 consecutive living donor liver transplant recipients. Methods: Renal resistive index (assessed by transabdominal ultrasound) and myocardial performance index (assessed by transthoracic echocardiography) will be measured just before operation, on termination of operation and then daily in the intensive care unit for 7 days. Patients will be observed for development of acute kidney injury.

Clinical Trial Description

This study aims to investigate whether combined doppler renal resistive index (RRI) assessed by transabdominal sonography and myocardial performance index (MPI) assessed by transthoracic echocardiography could predict early postoperative acute kidney injury in living donor liver transplant recipients. The primary outcome is the predictive value of renal resistive index and myocardial performance index for the onset of early post living donor liver transplant acute kidney injury. This prospective observational study will be conducted at Liver Transplantation Unit at Mansoura University from November 2022 till fulfillment of sample size after obtaining approval from Institutional Review Board (IRB). One hundred and five consecutive LDLT recipients will participate in this study after obtaining informed consents. They will be observed for the development of early postoperative acute kidney injury. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
