| Abstract: | We measured IgG, IgM and IgA antibodies to cow's milk proteins: alpha-casein, alpha-lactalbumin, bovine serum albumin, beta-lactoglobulin-a and beta-lactoglobulin-b in the sera of 29 pediatric patients with liver disease. IgG antibodies to bovine serum albumin, beta-lactoglobulin-a and beta-lactoglobulin-b and IgA antibodies to alpha-casein were elevated in most of the patients compared to age-matched controls. We postulate that, in patients with liver disease either increased intestinal uptake resulting in increased humoral response, or decreased hepatic clearance of food antigens intensifying a humoral response to these foreign antigens, may occur. |
