Hyperglobulinemia in alcoholic cirrhosis. Relationship with portal hypertension and intrahepatic portal-systemic shunting as assessed by Kupffer cell uptake

Abstract

The relative importance of portal hypertension and intrahepatic portal-systemic shunting in the pathogenesis of hyperglobulinemia is examined in 31 alcoholic cirrhotic patients and 6 patients with idiopathic portal hypertension. The degree of portal hypertension was evaluated by combined umbilicoportal and hepatic vein catheterization and the intrahepatic portal-systemic hunting was assessed by the Kupffer uptake of [125I]albumin microaggregates during a single passage through the liver. All patients had comparable severe portal hypertension and most had bled from ruptured varices; however, no demonstrable relationship could be found between portal hypertension and hyperglobulinemia. Elevated levels of serum gammaglobulins and immunoglobulins (mainly IgG) were observed only in cirrhotic patients, particularly those with markedly altered Kupffer cell uptake. It is concluded that intrahepatic portal systemic shunting as evaluated by the Kupffer cell uptake is more important than the collateral circulation secondary to portal hypertension in the pathogenesis of hyperglobulinemia in alcoholic cirrhotic patients.
