title: Pilot trial of prophylactic ursodiol to decrease the incidence of veno-occlusive disease of the liver in allogeneic bone marrow transplant patients.
abstract: Ursodiol is a hydrophilic, non-hepatotoxic bile salt indicated for the medical treatment of cholesterol gallstones. This pilot study explored the use of prophylactic ursodiol in an attempt to decrease the incidence and severity of veno-occlusive disease (VOD) of the liver following allogeneic bone marrow transplantation (BMT). Between February 1991 and January 1992, 22 consecutive patients undergoing BMT for hematologic malignancies received the BU(4)/CY(2) preparative regimen and CSA/MTX for GVHD prophylaxis. Ursodiol, 600-900 mg daily by mouth was begun at least 1 day prior to beginning the preparative regimen. Results for this pilot group were compared to a control group of 28 consecutive patients transplanted between June 1989 and January 1991 with the same regimen without ursodiol. There were no significant differences in disease or clinical status between the groups pretransplant. However, mean baseline AST levels were significantly higher in the ursodiol group, 28.0 U/l vs 18.1 U/l in the control group (p = 0.001). The median maximum bilirubin observed post-transplant was 2.35 mg/dl (range 0.9-45) in the ursodiol group, and 5.05 mg/dl (range 0.7-29.4) in controls. The incidence of VOD was 2/22 (9.1%) in the ursodiol group and 18/28 (64.3%) in controls (p = 0.0001). Death due to VOD occurred in 1/22 patients (4.5%) in the ursodiol group and in 6/28 (21.4%) controls (p = 0.12). Our data suggest that ursodiol may decrease the incidence of VOD in allogeneic BMT patients.
