Liver disease--a prominent cause of serum IgE elevation.
Serum IgE concentrations were elevated in thirty-seven out of sixty-seven patients (55%) with acute or chronic liver disease of widely differing aetiology. The mean IgE concentrations in these patients showed an eight-fold increase above that observed in control subjects. Increased IgE levels in patients with liver disease occurred in the absence of eosinophilia, clinical evidence of atopy or other known causes of IgE elevation. No IgE-containing plasma cells were detected in the liver biopsies from thirty-two of the sixty-seven patients tested. Peripheral blood T cells were significantly decreased from normal in the patients with liver disease, but no correlation emerged between serum IgE levels and absolute peripheral blood T-cell numbers. These findings emphasize the importance of liver disease as a significant cause of serum IgE elevation.
