[The hyperimmunoglobulin E syndrome]

Hyperimmunoglobulin E syndrome is a rare disease. The clinical and immunological features of HIE are discussed on the basis of a case history. A 28 year old woman had a life-long history of infections of the skin and the sinopulmonary tract. Because of elevated serum-IgE and several positive skin- and RAST-tests she had erroneously been classified as having multiple allergies including food allergy. We found a very high serum-IgE and negative challenge test. Additionally we found decreased oxidative metabolism of blood neutrophils and monocytes. This finding could explain the increased susceptibility to infections in HIE-patients.
