Outline of Final Research Achievements |
The aim of this study was to establish methods for early diagnosis and outcome prediction of delayed neurologic sequelae (DNS) after carbon monoxide (CO) poisoning. One hundred patients with acute CO poisoning were enrolled in this study. Based on the analyses of the clinical, laboratory, and radiological data, poor outcomes of DNS were associated with advanced age and earlier onset. Myelin basic protein (MBP) level in the cerebrospinal fluid (CSF) can serve as a sensitive predictor of both the development and outcomes of DNS. Participants underwent proton magnetic resonance spectroscopy (MRS). Within 1 week after CO exposure, NAA/Cr ratios were lower in patients with DNS than in those without DNS. At 1 month, Cho/Cr ratios were higher, and NAA/Cr and NAA/Cho ratios lower in patients with DNS. Proton MRS within 1 week may be useful for predicting DNS development. Proton MRS at 1 month may be useful for discriminating patients with DNS and predicting long-term outcomes.
