Evaluation and Management of Vitamin B12 Deficiency in Cirrhosis

Understanding B12 Status in Cirrhosis

• Vitamin B12 deficiency may develop rapidly in chronic liver disease due to diminished hepatic storage, according to the Journal of Hepatology guidelines 1, 2

Management Recommendations

• The Journal of Hepatology recommends treating confirmed or clinically suspected vitamin B12 deficiency in cirrhotic patients based on accepted general recommendations 1, 3
• A course of oral multivitamin supplementation is justified in decompensated cirrhosis patients, as vitamin status is not easily assessed and multivitamin supplementation is inexpensive with minimal side effects, as suggested by the Journal of Hepatology and Hepatology guidelines 1, 2, 4

Pitfalls to Avoid

• Avoid supplements containing manganese in cirrhosis patients, as they have elevated total body manganese levels that may accumulate in the basal ganglia, according to the Journal of Hepatology guidelines 1, 3
