Dynamic Monitoring of Circulating microRNA Changes in Patients With or Without Multiple Organ Failure

NCT ID: NCT03059524

Last Updated: 2017-02-23

Basic Information

• Recruitment Status: UNKNOWN
• Total Enrollment: 200 participants
• Study Classification: OBSERVATIONAL
• Study Start Date: 2017-01-31
• Study Completion Date: 2018-12-31

Brief 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 multiple organ failure.

2. 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 multiple organ 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.

Detailed Description

The ICU patients with multiple organ failure 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 multiple organ 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 normal patients without multiple organ failure.

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 standard miRNA detection method.
