The purpose of this biorepository is to collect blood from patients at the time of CO poisoning and at follow-up visits months to years later. These samples can be used in the future to learn more about how CO damages the heart and brain and whether blood tests could predict which patients will have problems after CO poisoning.

Primary Outcome Measures:
  • Biorepository for serum and plasma [ Time Frame: Within 24 hours of CO Poisoning ]
    Serum and plasma from blood collected within 24 hours of acute CO poisoning

Secondary Outcome Measures:
  • Serum and plasma (sub-acute) [ Time Frame: 4 weeks to 4 months after CO poisoning ]
    Serum and plasma collected 4 weeks to 4 months after poisoning

  • DNA Sequestration [ Time Frame: 24 hours to 12 months after CO poisoning ]
    DNA sequestered from blood drawn up to 1 year from CO poisoning

  • Serum and plasma (long-term) [ Time Frame: 4 months to 12 months after CO poisoning ]
    Serum and plasma collected 4 months to 12 months after poisoning

Biospecimen Retention:   Samples With DNA
Blood for plasma, serum, and DNA sequestration

Estimated Enrollment: 300
Study Start Date: February 2012
Estimated Study Completion Date: December 2018
Estimated Primary Completion Date: December 2018 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Patients with acute CO poisoning. Blood collection for biorepository only, no study intervention.
Other: No study intervention
There is no study-related intervention.

Detailed Description:

The investigators propose to establish a biorepository for storage of serum, plasma, and DNA collected from patients with carbon monoxide (CO) poisoning. Participants will also be evaluated for clinical outcome. The biorepository will include serum and plasma from CO-poisoned patients drawn at the time of injury as well as from blood drawn at clinical follow-up visits. The biorepository will also bank DNA from these participants.

These specimens can be analyzed in the future to elucidate potential inflammatory and immunological mechanisms that cause brain and heart damage and identify possible biological and genetic predictors of poor outcome.

Study Population
Study population includes patients who present to LDS Hospital or Intermountain Medical Center with symptomatic carbon monoxide poisoning and documented exposure to carbon monoxide.

Inclusion Criteria:

  1. Symptomatic carbon monoxide poisoning (headache, nausea, vomiting, dizziness, fatigue, muscle aches, slowed mentation, confusion, loss of consciousness, etc.).
  2. Documented exposure to carbon monoxide and no other reasonable explanation for their signs and symptoms.

Exclusion criteria:

  1. Pregnancy
  2. Age < 18 years
  3. Unable to obtain informed consent
  4. Subjects who, in the opinion of the investigator, are unable to comply with the requirements of the study or are unsuitable for any reason. The investigator and the Sponsor, prior to enrolling the subject on a case-by-case basis, must approve and document any waiver of these inclusion and exclusion criteria.
  5. Anemia requiring blood products within the last 4 months or hematocrit less than the laboratory normal reference range
