Other Clinical Trial - Quantifying Steatosis in Liver Transplant Donors

Status Active, not recruiting

Clinical Trial Summary

Non-alcoholic fatty liver disease is the most common chronic liver disease in Hong Kong. Its presence among donors of living donor liver transplants could affect the outcomes of recipients of liver transplantation. By using controlled attenuation parameter (CAP) measurements, the investigators aim to investigate the association of CAP measurements and severity of fatty liver among liver donors in the recipient outcomes of living donor liver transplantation.

Clinical Trial Description

Living donor liver transplantation (LDLT) has been increasing worldwide due to the critical shortage of cadaveric donors and the rising number of patients awaiting liver transplantation. The long-term survival rates of LDLT are now comparable to that of deceased donor liver transplantation. Currently, two-thirds of all liver transplants performed in Hong Kong are LDLT. The ultimate goal of LDLT is to guarantee donor safety while optimizing the best possible recipient outcome. Donor liver steatosis is a well-known factor which could influence graft function and long-term outcomes of the recipient allograft, and also affects donor hepatic recovery. When needed, pre-operative liver biopsy is often used for the quantitative assessment of donor steatosis, with LDLT not recommended when steatosis exceeds 30%. Nonetheless, liver biopsy is limited by its invasive nature, sampling error and intra-observer variations. Imaging evaluation for the quantification of steatosis via ultrasonography or computed tomography also has various pitfalls. There is currently no universal consensus on the ideal method in assessing donor steatosis. Controlled attenuation parameter (CAP) is a novel non-invasive method to quantify hepatic steatosis using ultrasonic attenuations to postulate fat content. It has been demonstrated to have good correlation with the degree of hepatic steatosis in both Western and Asian populations. The investigators aim to evaluate the application of CAP in the donor workup of LDLT and to investigate for its association with post-transplant outcomes. ;

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.
