To test the clinical usefulness of hepatic asialogycoprotein receptor analysis in liver surgery, we have conducted univariate and multivariate analysis for the detection of cirrhotic patients and prediction of morbidity after hepatic resection. Liver scintigraphy using technetium 99m-labeled asialoglycoprotein analog (TcGSA), ICG test, and CT hepatic volumetry were undertaken in 158 surgical patients including 111 who underwent hepatic resection. Hepatic functional parameters including Child-Pugh score, indocyanine green retention at 15 minutes (ICG-R15), clearance index (HH15), receptor index (LHL15), receptor concentration ([R]0), total hepatic receptor amount (R0) and hepatic parenchymal volume (HPV) were compared among patients with normal, cirrhotic, and non-cirrhotic damaged liver. Preoperative hepatic functional parameters, resected parenchymal fraction (RPf), operative blood loss, and total receptor amount of the remnant liver (R0-remnant) were compared between patients with and without signs of postoperative liver failure. All parameters but HPV were significantly different among patients with normal, cirrhotic, and noncirrhotic damaged liver. The multivariate analysis selected two significant (p <0.05) parameters, [R]0 and Child-Pugh score for the detection of liver cirrhosis. Of the 111 patients who underwent resection, 14 developed transient signs of postoperative liver failure. Of the parameters tested, presence of liver cirrhosis, LHL15, R0, intraoperative blood loss, and R0-remnant were significantly different between patients with and without signs of postoperative liver failure (p <0.05). The multivariate logistic regression analysis selected only R0-remnant as a significant (p = 0.022) parameter for the prediction of liver failure. The morbidity rate in patients with R0-remnant under 0.05 mmoles was 100%, and the rate decreased in inverse proportion to R0-remnant. In conclusion, combining the ASGP-R concentration ([R]0) and the Child-Pugh score best detected liver cirrhosis in surgical candidates. Cirrhotic patients and patients with a low R0-remnant are at higher risk for postoperative liver failure. The present study confirms the usefulness of hepatic asialogycoprotein receptor analysis in liver surgery.

Hemolysis in patients with advanced alcoholic liver disease is a common clinical problem and indicates an unfavorable prognosis. In many cases, the etiology of the hemolysis remains unknown. We observed three patients with alcoholic liver disease, suffering from severe hemolytic anemia, requiring multiple blood transfusions. Steroid therapy was ineffective and two of the patients died. All patients had a soluble variant of the human asialoglycoprotein receptor (s-ASGP-R) in their serum, as well as high titers of autoantibodies against this receptor (anti-ASGP-R). Consecutively, examination of 60 patients with alcoholic liver disease revealed a high incidence for s-ASGP-R (36%) and anti-ASGP-R (27%) in patients with alcoholic liver cirrhosis (ALC) compared to patients with cirrhosis due to viral hepatitis. The potential etiology of hemolysis was studied in vitro on erythrocytes from patients with ALC and from healthy donors. Isolated ASGP-R but not anti-ASGP-R bound to the surface of erythrocytes preferentially of blood group A1 and caused dose-dependent agglutination and hemolysis, while this phenomenon was much lower using erythrocytes of the blood group B and almost absent with blood group O-erythrocytes. Furthermore, agglutination and hemolysis only occurred in erythrocytes from ALC-patients or after the pre-treatment of cells with neuraminidase. ASGP-R induced agglutination and hemolysis was blocked by the competitive ASGP-R inhibitor asialofetuin. In conclusion, our results indicate a new, non-immunological mechanism for hemolysis in patients with alcoholic liver disease, mediated through agglutination by a soluble variant of the human asialoglycoprotein receptor and mechanical shear stress.
