Understanding the Role of Genes and Biomarkers in the Inflammation and Blood Clotting Process in Children With Acute Lung Injury

United States396 participantsStarted 2007-11

Plain-language summary

Acute lung injury (ALI)/Acute Respiratory Distress Syndrome (ARDS) is a severe lung condition that causes respiratory failure. This study will examine if differences in genes and biomarkers involved in the inflammation and blood clotting process may affect the severity of and recovery from ALI/ARDS in children hospitalized with the condition.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Hospitalized and requiring supplemental oxygen * Meets the American-European consensus definition of ALI/ARDS, defined as partial pressure of oxygen in arterial blood/fraction of inspired oxygen (PaO2/FiO2) ratio of less than 300 mm Hg, bilateral opacities on a chest radiograph, and either a pulmonary wedge pressure of less than 18 mm Hg or the absence of clinical evidence of left atrial hypertension * Acute pulmonary parenchymal disease (i.e., onset of bilateral infiltrates on chest radiograph within 48 hours of screening) * PaO2/FiO2 less than or equal to 300 mm Hg, regardless of the mean airway pressure * At least one arterial blood gas confirming partial pressure of oxygen/fraction of inspired oxygen (PO2/FiO2) ratio less than 300 mm Hg or Fi02/Sao2 on pulse oximetry of less than 320 Exclusion Criteria: * Clinical signs of left ventricular failure, pulmonary capillary wedge pressure greater than 18 mm Hg, or evidence, such as echocardiography, suggesting a cardiac basis for the pulmonary edema * Presence of right-to-left intracardiac shunt

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
