Background:
Methanol poisoning (MP) often causes acute mortality and morbidities; however, the association between MP and subsequent mortality has not been well studied.
Methods:
We conducted a nationwide population-based cohort study by identifying 621 participants with MP from the Nationwide Poisoning Database and 6210 participants without MP from the Longitudinal Health Insurance Database 2000 by matching the index date at a 1:10 ratio between 1999 and 2012. Comparison of the mortality rate between the two cohorts was performed by following up until 2013.
Results:
A total of 249 (40%) participants with MP and 154 (2.5%) participants without MP died during the follow-up (p < 0.001). Statistic analysis showed that participants with MP had a higher risk for mortality than did the participants without MP (adjusted hazard ratio [AHR]: 13.48; 95% confidence interval [CI]: 10.76-16.88). The risk of mortality was highest in the first 6 months after MP (AHR: 480.34; 95% CI: 117.55-1962.75). Hypertension, chronic obstructive pulmonary disease, liver disease, malignancy, drug abuse, and lower monthly income also predicted mortality.
Conclusions:
MP was associated with increased subsequent mortality. Close follow-up for comorbidity control and socioeconomic assistance are suggested for patients with MP.

Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.
