About this study

Maintaining the normal function of the pulmonary microvascular barrier is critical for ARDS treatment. To assess the relationship between the HAS2 protein level, HA content and the clinical prognosis of ARDS in patients with ARDS. Compare the HAS2 protein levels, HMW-HA and LMW-HA levels, endothelial injury indicators, and lungs in the blood of severe and non-ARDS severe patients and healthy adults admitted to the ICU. The correlation between permeability, disease severity and prognosis to explore the predictability of HAS2-HA on the clinical outcome of ARDS.

What is being measured

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

  1. 28-day fatality Rate

    28-day mortality (patients will be followed for 28 days)

    Measured: 28 days after enrollment

  2. 90-day fatality rate

    90-day mortality (patients will be followed for 90 days)

    Measured: 90 days after enrollment

  3. ICU hospital stay

    Length of ICU stay

    Measured: through study completion, an average of 4 week

  4. ICU fatality rate

    The ratio of the total number of deaths from all causes of the enrolled patients during ICU hospitalization.

    Measured: through study completion, an average of 4 week

  5. Wearing time from mechanical ventilation

    successful weaning defined as the absence of the requirement for ventilatory support, without reintubation

    Measured: through study completion,an average of 4 week

  6. Peripheral blood HMW-HA and LMW-HA levels

    ELISA method to separate and detect HMW-HA and LMW-HA levels(Units of Measure unit nM/ml)

    Measured: 0, 1, 3, 7 days after enrollment

  7. HAS2 protein content in peripheral blood

    ELISA method detects HAS2 protein in peripheral blood

    Measured: 0, 1, 3, 7 days after enrollment

Secondary outcomes (3)
  1. ENOS, ET-1, vWF levels in peripheral blood

    ELISA method to detect eNOS, ET-1, vWF in peripheral blood to evaluate endothelial cell damage(Measure unit ng/ml)

    Measured: 0, 1, 3, 7 days after enrollment

  2. Levels of bound mucinoglycans-1, nitric oxide, and acetylheparin sulfate in peripheral blood

    glycocalyx levels of the endothelium were assessed by measuring the levels of mucin polysaccharide-1, nitric oxide and acetyl heparan sulfate in peripheral blood by ELISA assay(Measure unit ng/ml)

    Measured: 0, 1, 3, 7 days after enrollment

  3. In peripheral blood, IL-1α, IL-6, neutrophils, lymphocytes, descending Procalcin, C-reactive protein value

    The ELISA method detects IL-1α and IL-6 in the blood, and records the blood neutrophils, lymphocytes, and vary in procalcin and C-reactive protein to assess the inflammatory response of ARDS(Measure unit pg/ml)

    Measured: 0, 1, 3, 7 days after enrollment

Questions about this trial

What is this clinical trial studying?

An observational study of Hyaluronic Acid, run by Southeast University, 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 11 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 24 Sep 2021. 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?

28-day fatality Rate (time frame: 28 days after enrollment). The study lists 7 primary outcomes in all. 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 24 Sep 2021.
