The effect of a single oral megadose of vitamin D provided as either ergocalciferol (D2) or cholecalciferol(D3) in alcoholic liver cirrhosis
Abstract
BACKGROUND AND AIMS: The goal of this study was to examine the effects of a single oral dose of 300 000 international units of either ergocalciferol (D2) or cholecalciferol (D3) on the plasma levels of 25-hydroxyvitamin D in patients with alcoholic liver cirrhosis.
METHODS: Inclusion criteria for this study were diagnosis of alcoholic liver cirrhosis and plasma levels of 25-hydroxyvitamin D less than 25 nmol/l. At baseline, patients were divided into Child–Pugh groups A, B, or C and were given one oral dose of 300 000 international units of ergocalciferol (D2 group, N= 23) or cholecalciferol (D3 group, N= 13). Plasma concentrations of 25(OH) vitamin D and vitamin D-binding protein were measured on days 0, 7, 30, and 90.
RESULTS: On days 7 and 30, patients from the D3 group had higher vitamin D levels than patients from the D2 group (P< 0.05). On day 7, vitamin D levels were found to correlate with Child–Pugh scores from patients in the D3 group. For patients in the D2 group, there was a positive correlation between vitamin D and vitamin D-binding protein as indicated by the area under the concentration versus time curves (Spearmen’s q =0.64 P< 0.001).
CONCLUSIONS: In patients with alcoholic liver cirrhosis, a single oral megadose of cholecalciferol was more effective than ergocalciferol in the treatment of vitamin D deficiency.Severe liver disease and low levels of vitamin D-binding protein were predictors for poor treatment outcomes.
