简要总结
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).

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).
Levels of serum mitochondrial (GDF15 and FGF21) and oxidative stress (8-OHdG and MDA) biomarkers pre- and post-HBO2 were compared, to assess whether HBO2 reduced stress. In addition, we evaluated whether the blood test results correlated with the patient's neurocognitive prognosis at 1 month.
