Evaluation of Chronic Liver Disease Condition and Transplant Prognosis Assisted by Eye Biological Parameters

December 25, 2024 updated by: Haotian Lin, Zhongshan Ophthalmic Center, Sun Yat-sen University
This study investigates the correlation between ocular biological characteristics and overall conditions before and after liver transplantation by collecting ocular biological characteristics. Explore whether it is possible to construct a clinical prediction model for liver transplantation by incorporating ocular biometric features, in order to optimize disease management before and after liver transplantation.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is a bidirectional cohort study, which retrospectively analysed data from a prospective database to construct a model, and prospectively collected patient information from preoperative to postoperative for model improvement and validation.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

The liver transplant population was recruited from individuals who went to cooperative medical unit for liver transplant registration, while normal individuals were recruited from the project responsible unit.

Inclusion Criteria:

  1. Age greater than or equal to 18 years old;
  2. Late stage liver disease patients waiting for liver transplantation treatment, as well as patients with varying degrees of cirrhosis;
  3. Can collect complete basic demographic information, liver function blood test indicators, liver pathology and imaging examination results;
  4. Can cooperate with eye OCT, OCTA and other examinations, and obtain qualified examination parameters;

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The performance of predicting the prognosis of liver transplantation
Time Frame: 1 week and 1 year after liver transplantation
Based on the outcomes of early graft dysfunction and 1-year graft survival rate, the area under the receiver operating characteristic curve, specificity, and sensitivity of the model
1 week and 1 year after liver transplantation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The performance of the model in assessing the severity of liver disease
Time Frame: 1 year
The confusion matrix of the model based on the MELD score results
1 year
