Serum proteins in liver cirrhosis: effects of shunt surgery.

The serum protein patterns of 38 patients with alcoholic liver cirrhosis were studied and compared with those of 15 patients with cryptogenic cirrhosis and of 18 normal volunteers. Serum prealbumin and albumin were significantly lowered in alcoholic liver cirrhosis in comparison with the normals. In liver cirrhosis, the four acute phase reactants, alpha 1-antiproteinase, orosomucoid, and haptoglobin and caeruloplasmin, showed a pattern in serum, in which alpha 1-antiproteinase was increased, orosomucoid and haptoglobin were decreased, and caeruloplasmin was normal. Immunoglobulins G, A and M were significantly elevated. IgA was significantly more elevated in patients with alcoholic disease than in patients with cryptogenic cirrhosis. The construction of a surgical portal-systemic shunt resulted in a significant decrease in serum concentrations of the acute phase reactants, while prealbumin, albumin and immunoglobulins were unaffected.
