Abstract
OBJECTIVES:
Severe alcoholic hepatitis has high short-term mortality. The aim of this study was to test the hypothesis that treatment of patients with alcoholic hepatitis with granulocyte colony-stimulating factor (G-CSF) might mobilize bone marrow-derived stem cells and promote hepatic regeneration and thus improve survival.
METHODS:
Forty-six patients with severe alcoholic hepatitis were prospectively randomized in an open study to standard medical therapy (SMT) plus G-CSF (group A; n=23) at a dose of 5?μg/kg subcutaneously every 12?h for 5 consecutive days or to SMT alone (group B; n=23) at a tertiary care center. We assessed the mobilization of CD34(+) cells on day 6, Child-Turcotte-Pugh (CTP), model for end-stage liver disease (MELD), and modified Maddrey's discriminant function (mDF) scores, and survival until day 90.
RESULTS:
There was a statistically significant increase in the number of CD34(+) cells in peripheral blood in group A as compared with group B (P=0.019) after 5 days of G-GSF therapy. There was a significant reduction in median Δ change% in CTP, MELD, and mDF at 1, 2, and 3 months in group A as compared with group B (P<0.05). There was marked improvement in survival in group A as compared with group B (78.3% vs. 30.4%; P=0.001) at 90 days.
CONCLUSIONS:
G-CSF is safe and effective in the mobilization of hematopoietic stem cells and improves liver function as well as survival in patients with severe alcoholic hepatitis.
