A Prospective Study of Application of Platelet Mapping in HBV-related Acute-on-chronic-liver Failure in China
An observational study of Thrombelastography,Acute on Chronic Liver Failure, Platelet, run by Nanfang Hospital, Southern Medical University at 1 site in China.
Trial summary
Ineffective hemostasis or a paradoxical prothrombotic state of Acute-on-chronic liver disease (ACLF) has been well established. Thrombelastography measures the dynamics of thrombin production and provides a global assessment of coagulation incorporating the cumulative effect of the interactions at various levels… Read more about this study

About this study
Ineffective hemostasis or a paradoxical prothrombotic state of Acute-on-chronic liver disease (ACLF) has been well established. Thrombelastography measures the dynamics of thrombin production and provides a global assessment of coagulation incorporating the cumulative effect of the interactions at various levels between plasma components and cellular component of coagulation. And through the platelet mapping, it can help provide a picture of patients' function of platelet. This study aims to explore the predictive role of platelet mapping in ACLF prognosis, organ failure developments and short term mortality.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Ineffective hemostasis or a paradoxical prothrombotic state of Acute-on-chronic liver disease (ACLF) has been well established. Thrombelastography measures the dynamics of thrombin production and provides a global assessment of coagulation incorporating the cumulative effect of the interactions at various levels between plasma components and cellular component of coagulation. And through the platelet mapping, it can help provide a picture of patients' function of platelet. This study aims to explore the predictive role of platelet mapping in ACLF prognosis, organ failure developments and short term mortality.

Questions about this trial
What is this clinical trial studying?
An observational study of Thrombelastography,Acute on Chronic Liver Failure, Platelet, run by Nanfang Hospital, Southern Medical 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 13 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: finished, as of the sponsor's last update on 6 Jun 2019. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
28-day mortality (time frame: 28-day). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 6 Jun 2019.
