Older adults (40+) with paracetamol poisoning face higher risks of liver failure and death. This age group, especially with alcohol abuse or delayed treatment, requires heightened medical attention for paracetamol overdose.
Area of Science:
- Toxicology
- Hepatology
- Clinical Medicine
Background:
- Paracetamol poisoning is common in young adults but fatalities disproportionately affect older individuals.
- This highlights a critical age-related disparity in paracetamol overdose outcomes.
Purpose of the Study:
- To investigate age as a significant risk factor for fulminant hepatic failure (FHF) and mortality in paracetamol poisoning.
- To identify specific age thresholds and associated risk factors for severe outcomes.
Main Methods:
- A 10-year study involving 746 transferred patients with severe paracetamol poisoning and 273 local patients.
- Retrospective chart analysis and multivariate logistic regression to assess age-related risks.
Main Results:
- While paracetamol poisoning is most frequent in 15-24 year olds, FHF and death predominantly occurred in patients aged 40 and above.
- Age 40+ significantly increased the risk of FHF (OR 2.33) and death/liver transplant (OR 4.18).
- Older age correlated with alcohol abuse and late presentation, exacerbating hepatotoxicity risks.
Conclusions:
- Age 40 years or older is an independent risk factor for FHF and mortality in paracetamol overdose.
- Patients aged 40+ with risk factors like alcohol abuse or late presentation should be classified as high-risk for paracetamol poisoning.

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.
