About

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.

Full 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.

Enrollment: 300 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

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
