Vitamin D Supplementation in Alcoholic Hepatitis

Assessment and Screening

Measure serum 25-hydroxyvitamin D [25(OH)D] levels in all patients with alcoholic hepatitis at presentation, as vitamin D deficiency (levels <20 ng/ml) occurs in 64-92% of chronic liver disease patients and is inversely correlated with disease severity and Child-Pugh score 1, 2

Supplement all patients with vitamin D levels below 20 ng/ml with oral vitamin D until reaching serum levels above 30 ng/ml, as recommended by EASL guidelines for chronic liver disease patients 1, 2, 3
Higher doses may be necessary in patients with more advanced disease, though specific dosing recommendations for alcoholic hepatitis are not established in current guidelines 1

Provide aggressive nutritional support with 35-40 kcal/kg/day and protein intake of 1.2-1.5 g/kg/day (or 1.5 g/kg/day in severely ill patients) 4, 5
Supplement with multivitamins including thiamine (B1), pyridoxine (B6), folate (B9), and cobalamin (B12), as water-soluble vitamin deficiencies are common in alcohol-related cirrhosis and multivitamin supplementation is cheap and substantially side-effect free 1, 2, 3
Administer parenteral thiamine generously if Wernicke's encephalopathy is suspected, as this is mandatory and takes priority over other vitamin supplementation 1, 2, 3

Vitamin D supplementation is supportive care, not disease-modifying therapy—the cornerstone of treatment remains complete alcohol abstinence and, for severe disease (MDF ≥32), corticosteroids (prednisolone 40 mg daily for 28 days) 4, 5
Never treat folate deficiency before correcting vitamin B12 deficiency, as this may mask B12 deficiency and precipitate neurological complications 6

Recheck 25(OH)D levels after supplementation to ensure target levels above 30 ng/ml are achieved 1, 2
Continue vitamin D supplementation long-term, as discontinuation will lead to recurrence of deficiency in the context of ongoing liver disease 1, 6
Monitor for response to overall treatment including abstinence, nutritional support, and disease-specific therapy (corticosteroids if indicated), as vitamin D is one component of comprehensive management 4, 5
