About this study

Official title: Risk Factors for Early Acute Lung Injury After Liver Transplantation in Children and the Prediction Vaulen

The goal of this observational study is to identify the risk factors for early acute lung injury (ALI) after liver transplantation in children .The main questions it aims to answer are what the risk factors are for early ALI in children and to evaluate the predictive value for the development of ALI.Participants will be divided into non-ALI group and ALI group according to whether they had ALI in a week after liver transplantation.Researchers will compare the difference between the two groups and use multivariate logistic regression analysis to screen the risk factors of ALI, and receiver operating characteristic(ROC) curve was used to evaluate the predictive efficacy of risk factors.

Read the detailed description

The goal of this observational study is to identify the risk factors for early acute lung injury (ALI) after liver transplantation in children and evaluate the predictive value for the development of ALI.Perioperative data of patients were obtained through electronic case information management system, anesthesia surgery clinical information system and clinical research database. Basic clinical data of children were recorded, including age, gender, alanine aminotransferase (ALT), aspartate aminotransferase (AST), International Normalized ratio (INR), childhood end-stage liver disease score (PELD) and other indicators.The expression levels of serum microRNA-122, microRNA-21, S100A9,S100A8 ,follistim like protein 1(FSTL1), tumor necrosis factor-α (TNF-α) and interleukin-1β(IL-1β) were recorded immediately after induction of anesthesia (T1), 10 min at anhepatic stage (T2), 30 min at new hepatic stage (T3) and immediately after abdominal closure (T4). Intraoperative fluid intake and outflow, ALT, AST, and serum bilirubin peaks in the first week after surgery were recorded.Murray score was used to determine whether ALI occurred one week after surgery, and the children were divided into non-ALI group and ALI group. Multivariate logistic regression analysis was used to screen the risk factors of ALI, and ROC curve was used to evaluate the predictive efficacy of risk factors.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. the score of acute lung injury

    Murray score was scored from four aspects: chest X-ray, hypoxemia score, positive end-expiratory pressure and lung compliance. The total score was the sum of the scores of all parameters the sum of the number of parameters adopted. The higher the score, the more serious the injury was.

    Measured: 1 week after liver transplantation

Secondary outcomes (1)
  1. the expression level of serum microRNA-122,microRNA-21,S100A9,S100A8, TNF-α ,IL-1β and FSTL-1

    Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression of microRNA-122,microRNA-21,S100A9,S100A8,TNF-α ,IL-1β and FSTL-1 in serum.

    Measured: immediately after induction of anesthesia (T1), 10 min at anhepatic stage (T2), 30 min at new hepatic stage (T3) and immediately after abdominal closure (T4)

Questions about this trial

What is this clinical trial studying?

An observational study of Acute Lung Injury and Liver Transplantation, run by Tianjin First Central Hospital.

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 4 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: status not confirmed, as of the sponsor's last update on 16 May 2023. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

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?

the score of acute lung injury (time frame: 1 week after liver transplantation). 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 16 May 2023.
