Massive polyclonal hyperimmunoglobulinemia E, eosinophilia and increased IgE-bearing lymphocytes.
A patient (E.M.) with marked eosinophilia and hyperimmunoglobulin E (IgE) has been followed for 4 years. Peripheral blood eosinophilia reached levels in excess of 18,000 cells/mm3 and serum IgE concentration increased to more than 210,000 units/ml (about 0.48 mg IgE/ml). The IgE has both lambda and kappa light chains and is therefore considered polyclonal. The patient has an increase in peripheral blood lymphocytes which stain for surface IgE. Transfer of the patient's plasma (plasmsEM) to a rhesus monkey did not induce peripheral boood eosinophilia. The half life of IgEEM in a rhesus monkey was 2.2 days, which is similar to the half life of myeloma IgE in human subjects. The condition was not associated with defined morbidity except for mild persistent pruritus. Various studies revealed no evidence for atopic parasitic, immune deficiency or neoplastic disease.
