Control serum levels of IL-6 measured by ELISA in 30 healthy blood donors or volunteers were 18±34 pg/ml (mean ± SD). Pretransplant serum levels of IL-6 in 169 adult candidates for liver transplantation were significantly higher than control in those with fulminant hepatitis (203±232 pg/ml), alcoholic cirrhosis (116±257 pg/ml), and hepatocellular carcinoma (82± 105 pg/ml). With these data as background, plasma or serum levels of IL-6 were monitored in 24 adult patients after first OLT and correlated with the clinical courses and the histopathological diagnosis of rejection. Serum or plasma levels of IL-6 decreased after transplantation regardless of pretransplant value. Four patients with infection subsequently developed continuously high IL-6 values. In the 20 of 24 patients who did not have infection, significantly higher levels of IL-6 were consistently found 0-4 days before histopathological diagnosis of rejection (131±78 pg/ml) compared with significantly lower values in patients without rejection episodes (40±21 pg/ml). The elevations of IL-6 were spike shaped, did not correlate well with the histopathological grades of rejection, and were highly responsive to augmented immunosuppression. These 20 cases were classified as: Group 1, no spikes of IL-6 after liver transplantation; group 2, single spike of IL-6 after liver transplantation; and group 3, multiple spikes of IL-6 after liver transplantation. The combined early and late graft loss of each group was 0% (group 1), 25% (group 2), and 67% (group 3). We conclude that daily monitored serum or plasma IL-6 levels can be a good premonitor of liver allograft rejection and also a useful predictor of long-term graft outcome. © 1994 by Williams & Wilkins.
