Study summary

This prospective cohort study aims to evaluate whether blood levels of soluble receptor for advanced glycation end products (sRAGE), Club Cell Protein-16 (CC16), and Syndecan-1 measured early after severe chest trauma can predict the development of acute respiratory distress syndrome (ARDS) and in-hospital mortality. Adult patients aged 18 years or older admitted with severe blunt or penetrating chest trauma will be enrolled. Clinical data, injury severity, laboratory findings, imaging results, and clinical outcomes will be recorded. Patients will be followed daily during the first 7 days after admission for the development of ARDS, and in-hospital mortality will be recorded until discharge or death. The findings may help identify patients at high risk of respiratory complications and poor outcomes after severe chest trauma.

Study population

The study population will include adult patients aged 18 years or older admitted to the trauma unit with severe blunt or penetrating chest trauma. All eligible participants will undergo clinical assessment, routine laboratory and radiological evaluation, and single blood sampling for measurement of serum sRAGE, CC16, and Syndecan-1 levels. Participants will be followed prospectively for the development of ARDS during the first 7 days after admission, while in-hospital mortality will be recorded until hospital discharge or death.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Adult patients aged 18 - 60 years old.

    • Patients with blunt or penetrating severe chest trauma.
    • Chest Abbreviated Injury Scale (Chest AIS ≥3).
    • Admission within 24 hours of injury.
    • Patients admitted to the Trauma Unit or Trauma ICU.
    • Written obtained from the patient or legally authorized representative.

Exclusion criteria

Exclusion Criteria:

  • h. Age below 18 years or above 60 years old (to ensure a homogeneous adult study population and avoid age- related physiological differences).

    • i. Hospital admission more than 24 hours after injury (to ensure early biomarker measurement before secondary inflammatory changes occur).
    • j. Previous diagnosis of acute respiratory distress syndrome before admission (to ensure that ARDS outcomes are attributable to the index chest trauma).
    • k. Pre-existing chronic interstitial lung disease (to avoid baseline pulmonary abnormalities that may influence biomarker levels and respiratory outcomes).
    • l. Acute exacerbation of requiring hospitalization (to minimize confounding from pre-existing acute pulmonary inflammation).
    • m. Active pulmonary infection before trauma (to exclude pre-existing pulmonary inflammation that may alter biomarker levels and increase the risk of ARDS independently of trauma).
    • n. End-stage chronic liver disease (to avoid altered inflammatory responses and poor clinical outcomes unrelated to chest trauma).
    • o. End-stage renal disease requiring dialysis (to avoid altered clearance of circulating biomarkers and independently increased mortality risk).
    • p. Active receiving chemotherapy or radiotherapy (to exclude patients with cancer-related systemic inflammation and that may affect biomarker levels and outcomes).
    • q. Pregnancy (because physiological changes during pregnancy may influence biomarker levels and respiratory function).
    • r. Patients transferred from another hospital more than 24 hours after injury (to ensure standardized early clinical assessment and biomarker sampling within the predefined study period).
    • s. Refusal to participate in the study (because is required for study enrollment).
    • t. Connective tissue diseases
    • u. Severe burns and major inhalational injury v. Immunosuppressive therapy
    • w. Chronic systemic inflammatory diseases
    • x. Severe obesity ( >40), if relevant.
    • y. Poly trauma with AIS> or = 3 outside the chest.
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Groups and cohorts

  • Severe Chest Trauma Cohort

    Adults aged 18 years or older with severe blunt or penetrating chest trauma admitted to the trauma unit and enrolled in the study. Participants will be followed prospectively for the development of acute respiratory distress syndrome and in-hospital mortality.

    Other: No intervention - observational study

Interventions

  • OtherNo intervention - observational study

    No intervention is assigned. Participants receive standard clinical care, and the study prospectively observes clinical outcomes and biomarkers following severe chest trauma.

What researchers measure

Primary outcomes

  1. Development of acute respiratory distress syndrome (ARDS), diagnosed according to the 2024 Global Definition of ARDS.

    Acute respiratory distress syndrome (ARDS) will be diagnosed according to the 2024 Global Definition of ARDS, which updates and expands the Berlin Definition. ARDS is defined by acute hypoxemic respiratory failure occurring within one week of a known clinical insult, with bilateral pulmonary opacities on chest imaging (chest radiography, computed tomography, or lung ultrasound) not fully explained by cardiac failure or fluid overload, and impaired oxygenation (PaO₂/FiO₂ ≤300 mmHg or SpO₂/FiO₂ ≤315 under specified respiratory support). Severity is classified as mild, moderate, or severe according to the degree of hypoxemia). Two independent intensivists blinded to biomarker results will independently adjudicate ARDS diagnosis according to the 2024 Global Definition Two independent intensivists blinded to biomarker results will independently adjudicate ARDS diagnosis according to the 2024 Global Definition

    Time frame: From admission through 7 days

Secondary outcomes

  1. In-hospital mortality.

    Time frame: From hospital admission until hospital discharge or death, whichever occurs first, assessed up to 28 days after admission.

  2. ICU length of stay.

    Time frame: From ICU admission until ICU discharge or death, with the outcome assessed up to 28 days after ICU admission.

  3. Need for invasive mechanical ventilation

    Requirement for invasive mechanical ventilation during hospitalization following severe chest trauma.

    Time frame: Assessed daily from hospital admission through Day 7, or until initiation of invasive mechanical ventilation, hospital discharge, or death, whichever occurs first.
