Trial summary

The accuracy of ultrasound elastography for assessing liver fibrosis by measuring liver stiffness (elastic modulus) is better than traditional method. Elastography has certain advantage such as non-invasive, simple, real-time and it has been recommended by clinical guidelines. Read more about this study

About this study

Official title: Guangdong Key Laboratory of Liver Disease Research, Department of Medical Ultrasound, The Third Affiliated Hospital of Sun Yat-sen University

The accuracy of ultrasound elastography for assessing liver fibrosis by measuring liver stiffness (elastic modulus) is better than traditional method. Elastography has certain advantage such as non-invasive, simple, real-time and it has been recommended by clinical guidelines.

However, some chanllenging scientific problems showed up with further research and clinical practice. Firstly, present elastography machines can only calculate liver stiffness from shear wave speed or elastic modulus but ignore other physical characteristics such as tissue viscosity. So far, present technique simply assume liver as an idealized model with isotropic elasticity to assess liver fibrosis while liver is actually anisotropic and viscoelastic. What's more, theoretically, there are not only different solid state structures such as cell organization and vessel but also flowing liquid such as blood and bile. Thus, ignoring viscosity and evaluating elasticity only is unreasonable. In the other hand, a number of confounding factors have been found to influence liver stiffness measurement by elastography. Different pathological chang of liver including inflammation, necrosis, cholestasis and inhomogeneity among the individuals such as obesity, ascites, et,al. will decrease the accuracy of liver stiffness measurement and liver fibrosis staging by elastography.

In fact, liver fibrosis is a dynamic process. Liver fibrosis is a reaction of compensation and repair for inflammation and necrosis as well as a contributing factor for liver damage. This dynamic process constitutes the common characteristic of chronic liver disease and result in the complicated biological mechanical characteristics of liver. In consequence, how to measure liver viscosity and elasticity respectively, and to evaluate liver fibrosis stage and Inflammation degree accurately during the complicated and dynamic pathological process is the key scientific problem demanding solution, which is also the urgent requirement of related fundamental research and clinical practice.

Therefore, this project plan to apply LOGIQ E viscoelastography machine as research tool, rat liver fibrosis model and rat liver failure model as research object to investigate the correlation between liver viscoelastography measurement and liver fibrosis stage and Inflammation degree. The investigators also aim to assess the feasibility of using ulstrasound viscoelastography to evaluate liver fibrosis stage and Inflammation degree dynamically.

Questions about this trial

What is this clinical trial studying?

A study testing ultrasound viscoelasticity in people with Cirrhosis and Liver Diseases, run by Third Affiliated Hospital, Sun Yat-Sen University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 2 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Xue Lu, PHD (13560357934, luxue2@mail2.sysu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

liver fibrosis stage (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03777293, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Sep 2021.
