Serum IgE concentrations were determined and IgE turnover studies were performed in control individuals as well as in patients with several disease states. Patients with common variable hypogammaglobulinemia, thymoma and hypogammaglobulinemia, ataxia telangiectasia, and selective IgA deficiency had significantly decreased mean serum IgE concentrations. In turnover studies, this was found to be due to decreased IgE synthesis. In spite of these depressed mean values, some patients with common variable hypogammaglobulinemia had normal serum IgE concentrations and synthetic rates. Patients with the Wiskott-Aldrich syndrome had a significantly elevated mean serum IgE concentration. In one of four patients studied with the turnover technique, a strikingly high IgE concentration was present and was associated with an elevated IgE synthetic rate. Three other patients had both normal serum IgE concentrations and synthetic rates. Patients with chronic lymphocytic leukemia had significantly decreased mean serum concentrations and synthetic rates for IgE. The depressed IgE synthesis was associated with a significantly prolonged IgE half-life. Patients with Hodgkin's disease had significantly increased serum IgE concentrations. One of three patients studied had a high serum IgE concentration and synthetic rate of IgE. The two other patients had normal serum IgE concentrations associated with normal synthetic rates. Finally patients with protein-losing enteropathy or familial hypercatabolic hypoproteinemia had normal IgE concentrations associated with normal IgE metabolic parameters. In these cases, the disorder in the catabolic rate was not severe enough to affect the total amount of circulating IgE because IgE normally has a very high fractional catabolic rate. In general, IgE levels in a variety of disease states were correlated with IgE synthetic rates and abnormalities in the catabolic rate of IgE in disease did not exert an important effect on IgE concentration.

An infant with allergic eosinophilic gastroenterocolitis is described. The patient presented with vomiting, diarrhea, gastrointestinal bleeding, and failure to thrive. Anemia, hypoproteinemia, and peripheral eosinophilia were also present. Gastrointestinal endoscopy revealed multiple mucosal ulcerations in the stomach, small intestine, and colon. Histological study of the affected areas showed infiltration of the mucosa by eosinophils, increased mucosal IgE plasma cells, and activated intraepithelial lymphocytes. Treatment with corticosteroids resulted in clinical and histological remission.

A syndrome of chronic diarrhea, vomiting, and failure to thrive was described 35 years ago. The syndrome was caused by damage in the jejunum after ingestion of cow's milk. Symptoms appeared in young infants shortly after introduction of cow's milk formula. Patients had moderate steatorrhea, decreased absorption of D-xylose, and, often, iron-deficiency anemia and hypoproteinemia. They had strong IgA and IgG antibodies to cow's milk. IgE antibodies to cow's milk were negative, as a rule. Indicators of cell-mediated immune reaction to cow's milk proteins were often positive. Patients were tolerant to cow's milk by the age of 3 years. Malabsorption was due to damage to the jejunal mucosa: Varying villus atrophy was associated with inflammation in surface epithelium and lamina propria. The epithelial cell renewal rate increased. Surface epithelial cells decreased in height, with short, furry microvilli and large aggregates of lysozymes. The number of intraepithelial lymphocytes was markedly increased, but normalized during cow's milk elimination. Most of these lymphocytes had alpha/beta T-cell receptors, and many were cytotoxic. Some specimens had an increase in gamma/delta T-cell receptor-bearing cells. In the lamina propria, CD4+ cells predominated, and some of them were activated. IgA- and IgM-containing cells were markedly increased during cow's milk exposure, but IgE cells were not abnormal. The density of eosinophils was moderately increased. Secretion of interferon-gamma by cells isolated from patients' intestines was markedly increased. Morphologic and immunologic findings suggest that T-cell-mediated reaction to proteins in cow's milk is present in the small intestines of patients with this syndrome and causes this enteropathy.
