An Autopsy-Based Comparative Study on Alcohol-Related Versus Non-Alcohol-Related Liver Pathologies

The liver is uniquely exposed to metabolic, toxic, infectious and circulatory insults. While chronic alcohol use remains a dominant cause of progressive liver disease, a substantial burden of non-alcohol-related and clinically silent liver pathology is encountered at autopsy.

To compare alcohol-related versus non-alcohol-related liver lesions detected at autopsy using six parameters: age, sex, histopathological lesions, gross morphology, cause of death correlation, and incidental/silent findings.

The present study was undertaken in a leading tertiary care institute of North India to deepen the understanding of the distinct histopathological features and progression patterns of liver diseases influenced by alcohol consumption versus other etiologies, using autopsy specimens as a definitive diagnostic tool. Liver specimens were examined grossly and histologically (H&E, with special stains when indicated), and demographic/inquest data were reviewed to classify cases into alcohol-related and non-alcohol-related pathology groups.

Alcohol-related pathology predominated in males (M:F ≈ 11.5:1) and in the third to fifth decades, with the classical histological spectrum of fatty change, hepatitis and cirrhosis being most frequent. The study observed fatty change in 34% of cases, hepatitis in 14% and cirrhosis in 8%. Grossly, greasy and nodular livers were common in alcohol-related cases. These lesions frequently contributed to natural deaths related to hepatic decompensation or multi-organ failure. Nonalcohol-related findings (congestion 6%, granulomas 2%, abscess 2%, incidental neoplastic or infiltrative lesions) were more heterogeneous and frequently incidental in trauma, poisoning, or cardiac deaths.

Autopsy histopathology distinguishes a predictable alcohol-related triad from a diverse spectrum of nonalcoholic liver pathology.
