In a prospective cohort of 72 adults with confirmed alcoholic liver disease (ALD) at a Kathmandu rehabilitation center, just one month of alcohol abstinence drove dramatic normalization of hepatic enzymes: alanine aminotransferase fell from 156.6 to 55.2 U/L (~65% reduction), aspartate aminotransferase from 159.5 to 62.2 U/L (~61%), alkaline phosphatase from 161.7 to 89.9 U/L (~44%), and bilirubin from 1.69 to 1.33 mg/dL — all statistically significant at p<0.001. Alkaline phosphatase showed the strongest pre-to-post correlation (r=0.94), suggesting individual liver recovery trajectories are highly consistent.
This finding reinforces a foundational but still clinically underappreciated principle: the liver retains remarkable regenerative capacity even after sustained alcohol-related injury, and the trajectory of recovery begins within weeks, not months. The magnitude of enzyme reduction here — over 60% for transaminases in just 30 days — aligns with prior Western cohort data but quantifies this recovery in a South Asian rehabilitation context, where such data are sparse.
Limitations are significant: the sample is small (n=72), single-center, lacks a control group, and relies on a rehabilitation setting where abstinence compliance is enforced — real-world adherence would likely be far lower. Longer follow-up data on whether enzyme normalization translates into reduced cirrhosis progression or mortality is absent. Still, for clinicians and patients alike, this confirms that abstinence delivers measurable, rapid biochemical benefit — a compelling motivational message for alcohol-dependent adults.
