Acute Methanol Toxicity: Clinical Correlation with Autopsy Findings, a Descriptive Study

Area of Science:

• Toxicology
• Clinical Medicine
• Public Health

Background:

• Methyl alcohol poisoning is a recurrent issue in India, frequently linked to illicitly brewed alcohol, causing numerous fatalities.
• Between 2006 and 2015, over 11,830 deaths were attributed to spurious liquor consumption nationwide.
• Symptoms of methanol intoxication vary in severity based on exposure levels and promptness of medical attention.

Purpose of the Study:

• To detail the clinical presentation, management strategies, and patient outcomes during a recent methanol outbreak.
• To establish a basis for improved diagnosis and treatment protocols for methanol poisoning.
• To correlate clinical features with autopsy findings in fatal cases.

Main Methods:

• A retrospective, descriptive study analyzing clinical data and autopsy reports of methanol intoxication patients.
• Study conducted at King George's Medical University, Lucknow, focusing on patients from Barabanki and Sitapur district outbreaks in May 2019.
• Inclusion criteria based on predefined clinical characteristics of methanol intoxication.

Main Results:

• 33 patients were analyzed, with average consumption of 223 mL of methanol; symptom onset typically occurred between 12-24 hours.
• Common symptoms included gastrointestinal issues (100%), visual disturbances (97%), and central nervous system manifestations (91%); 15% presented in coma.
• Metabolic acidosis was prevalent (90%); 30 patients recovered, two died, and one absconded. Autopsy revealed cerebral edema, hyperemia, and in one case, characteristic putaminal necrosis.

Conclusions:

• Methanol intoxication poses a serious threat in developing nations, underscoring the importance of timely medical intervention.
• Effective management of methanol intoxication is achievable even with limited resources if cases are identified and treated promptly.
• This study emphasizes that ground-level interventions can significantly reduce mortality rates associated with methanol poisoning.
