Serum levels of the actin scavenger Gc-globulin (group-specific component, vitamin D-binding protein), a member of the albumin multigene family, are decreased in severe liver disease but have not been evaluated in relation to liver transplantation. We measured Gc-globulin and Gc-globulin-actin complex ratio daily for 2 weeks after transplantation in 17 patients with end-stage liver disease. Before transplantation, Gc-globulin levels were significantly less in the patients than in healthy controls (235 +/- 106 v 340 +/- 35 mg/L, respectively; P<.001), whereas complex ratio level was in the normal range. Five patients (group N) had pretransplantation Gc-globulin values within the normal range (mean +/- 2 SD), and 12 patients had subnormal values (group S). In group N, mean Gc-globulin levels posttransplantation remained stable at a lower level than before transplantation but still within normal range. In this group, cold ischemia time correlated inversely with Gc-globulin levels on day 2 (r = -0.88; P <.05). In group S, normal mean levels were reached at a mean of 11 days after transplantation. However, almost half these patients had subnormal Gc-globulin levels at day 14. Complex ratio levels remained normal in the study period in both groups. Prothrombin index levels (plasma coagulation factors II, VII, and X) were identical in both groups and returned to normal 7 days posttransplantation, whereas plasma albumin levels were less than normal in both groups and further decreased after transplantation. In conclusion, the maintenance (group N) or reestablishment (group S) of serum Gc-globulin to normal levels occurred in the early posttransplantation course in the same time frame as the prothrombin index. Gc-globulin synthesis seems unrelated to albumin synthesis. A prolonged cold ischemia time may cause reduced Gc-globulin levels early after transplantation.
