Trial summary

Thyroid hormones are substances naturally made by the body and are important to many of your body's basic functions such as breathing and brain function. We are investigating whether or not these hormones are at lower levels in critically ill children which could lead to further health problems. Read more about this study

About this study

Official title: Thyroid Hormone Deficiency in Critically Ill Children

Thyroid hormones are substances naturally made by the body and are important to many of your body's basic functions such as breathing and brain function. We are investigating whether or not these hormones are at lower levels in critically ill children which could lead to further health problems. We hope to get a better understanding of hormone levels and their effects on critically ill children to better help other children in the future.

Read the detailed description

We hypothesize that critically ill children that require vasoactive infusions and/or invasive mechanical ventilation have thyroid hormone alterations. We will measure TSH, tT3, fT3, rT3, tT4, fT4, adn tyrosine concentrations in critically ill children with hypotension and/or respiratory failure and correlate thyroid hormone alterations to severity of illness, intensity of therapeutic interventions, and associated morbidity and mortality by using clinical outcomes parameters.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Blood drawsOther

    Also called Critically Ill Children, Vasoactive Infusions in Children, Mechanical Venilation in Children, Thyroid Deficiency

    17 mls of blood will be drawn over a 5 day period from either a central venous catheter/arterial line or with scheduled phlebotomy. The following labs will be run tT3, fT3, rT#, tT4, fT4, TSH, and tyrosine.

Study groupRoleWhat they receive
1Patients who are receiving vasoactive medications and/or are mechanically ventilated.
Receives: Other: Blood draws

What is being measured

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

  1. Certain critically ill children requiring vasoactive infusions and/or mechanical ventilation have low concentrations of tT3, fT3, tT4, fT4, elevated rT3, adn inappropriate low/normal TSH.

    Measured: When patient has completed the study.

Secondary outcomes (2)
  1. Critically ill children with more severe thyroid hormone deficiencies will have greater severity of illness, intensity of therapeutic intervention, organ dysfunction, and increased morbidity and mortality.

    Measured: When study is completed.

  2. Critically ill children requiring vasoactive infusions and/or mechanical ventilation are a population in the ICU that has thyroid hormone pertubation and significant morbidity and mortality.

    Measured: At completion of study

Questions about this trial

What is this clinical trial studying?

An observational study of Hypotension and Respiratory Failure, run by Children's Hospital of Philadelphia at 1 site in United States.

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 5 inclusion and 8 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: stopped early, as of the sponsor's last update on 12 Mar 2015. 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 United States. 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 was stopped early (reason given: Sluggish enrollment.). 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?

Certain critically ill children requiring vasoactive infusions and/or mechanical ventilation have low concentrations of tT3, fT3, tT4, fT4, elevated rT3, adn inappropriate low/normal TSH. (time frame: When patient has completed the study.). 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 12 Mar 2015.
