Comparative Study of Circulating microRNA Changes in Patients With Liver

Status Recruiting

Clinical Trial Summary

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.

Clinical Trial 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. ;

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.
