Prognostic Biomarkers in CO Poisoning

Status Completed

Clinical Trial Summary

Mitochondrial and oxidative stress participate in the pathogenic mechanisms of carbon monoxide (CO)-induced toxicity. Thus, serum indicators of mitochondrial and oxidative stress could be useful for predicting neurocognitive prognosis of post-CO poisoning. This prospective observational study of consecutive patients requiring hyperbaric oxygen therapy (HBO2) for acute CO poisoning measured serum biomarkers of mitochondrial (growth differentiation factor 15 [GDF15]; fibroblast growth factor 21 [FGF21]) and oxidative (8-Oxo-2'-deoxyguanosine [8-OHdG] and malondialdehyde [MDA]) stresses at arrival at the emergency department (0 h), and at 24 h and 7 days after HBO2 completion. We evaluated neurocognitive outcomes using the Global Deterioration Scale (GDS; favorable [1-3 points] or poor [4-7 points] outcomes).

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
