Comparative Study of Circulating microRNA Changes in Patients With Liver Injury and Healthy Subjects

May 24, 2017 updated by: University of Electronic Science and Technology of China

The objectives are to:

  1. validate a panel of tissue-specific miRNAs that are differentially expressed in the plasma of patients with and without liver injuries
  2. investigate the physiological range of the circulating miRNA panel in Healthy Subjects and under stress
  3. investigate the dysregulation of circulating miRNA panel and their prognostic and predictive values in clinical outcomes in identifying patients at high risk for mortality and acute liver failure.

This trial involves peripheral blood sampling from subjects at their earliest presentation and remaining stays in the hospitalization in the emergency department. The investigators will develop panels of miRNAs that are specific indicator of early onset of major organ failures, and correlate clinical outcomes with these miRNAs.

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.

Detailed Description

The ICU patients after surgery or under chemotherapies in sponsor's institutes will be enrolled in this observational cohort of investigation. Whole blood samples will be separated immediately into plasma for storage. The participants will have their 2nd and 3rd samples obtained at 24-48 hours and 48-72 hours respectively. The schedule of most of sampling schedule is designed in concordance with the ICU routines to avoid extra burdens on patients. The plasma samples will be used as prognostic markers in prognostic and predictive values in identifying patients at high risk for mortality and acute liver failure. Patients who are discharged will be tracked for any clinical recurrence of the diseases every 28 days to assess the diagnostic accuracy of the miRNA biomarkers that are measured.

The 2nd objective will be assessed by measuring the concentration of miRNAs in recruited healthy volunteers before and after a brief public speech. The circulating miRNAs will be detected directly from 1 - 5 ul of plasma samples with the miRFLP assay. This capillary electrophoresis-based miRNA quantification method detects multiple miRNAs in absolute copy number in smaller sample signature with negligible batch to batch variation, thus providing a standardizable miRNA detection method.

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

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

This research project will recruit a cohort of prospective observational cancer patients in ICU after surgery or chemotherapy. Admitted patients will be followed-up in the inpatient units in concordance with ICU protocols. Upon discharged, patients will be followed-up in every 28 days for any disease recurrence and clinical outcomes. Healthy controls will also be recruited to demonstrate the physiological level of different circulating miRNAs.

Description

Inclusion criteria for healthy controls:

Adults 18 years and above

Exclusion criteria for healthy controls:

Underlying chronic inflammatory condition (e.g. inflammatory bowel disease) Underlying autoimmune disease (e.g. rheumatoid arthritis, systemic lupus erythematosus) Pre-existent liver disorder User of any prescribed medicine or over the counter drugs in prior 7 days.

Inclusion criteria for subjects:

Adults 18 years and above Has condition related to ICU enrollment cause

Exclusion criteria for subjects:

Age below 18 years Known pregnancy Treating physician deems aggressive care unsuitable Unable to provide informed consent or comply with study requirements

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 concentration of circulating miRNA expression quantitated in absolute copy numbers in ICU patients and their correlation with liver failure
Time Frame: Three years
The concentration of circulating miRNAs in absolute quantification in comparison to the severity of liver injury (control vs. liver injury vs. acute liver injury). To investigate the potential prognosis of liver failure by the expression difference of the miRNA panel at the onset of liver injury. Sensitivity, specificity and the potential scopes of selected miRNA in the miRNA panel to distinguish different severity of liver injury and against standard clinical parameters, serum amonotransferases (ALT, AST), total bilirubin measurement.
Three years

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 possible physiological range of selected miRNAs in healthy subjects and the performance metrics of the miRNA detection methodology
Time Frame: Three years
The concentration of circulating miRNAs in healthy subjects under resting condition and/or under stress. To investigate the potential physiological levels of the miRNA panel in healthy control as baselines.
