title: Elevated urinary histamine in the hyperimmunoglobulin E and recurrent infection (Job's) syndrome: association with eczematoid dermatitis and not with infection.
abstract: To test the hypothesis that IgE-mediated release of histamine may be, in part, responsible for the abnormal inflammatory response observed in the hyperimmunoglobulin E (HIE) and recurrent infection syndrome, urine and plasma histamine levels were measured. Twenty-four-hour urinary histamine concentrations from 15 patients with HIE (23.7 +/- 6.9 micrograms/24 hr) were significantly elevated (p less than 0.001) compared to a large historical control population (10.5 +/- 0.7 micrograms/24 hr; n = 97). However, urinary histamine levels in HIE were much less abnormal (p less than 0.01) than in five patients with biopsy-proven systemic mastocytosis (159 +/- 62 micrograms/24 hr) and were not significantly elevated when levels were compared to 13 concurrently studied normal subjects (10.1 +/- 1.7 micrograms/24 hr) and nine patients with chronic granulomatous disease (8.1 +/- 1.2 micrograms/24 hr). Overall, there was no clear relationship between urine histamine values and the presence of infection as well as no significant correlation between urine histamine and total IgE or anti-Staphylococcus aureus IgE. However, urine histamine levels in a subgroup of six patients with HIE with chronic eczematoid dermatitis (42.4 +/- 12.5 micrograms/24 hr) were elevated compared with values from the historical control subjects (p less than 0.001), the concurrent control subjects (p less than 0.01), the patients with chronic granulomatous disease (p less than 0.01), and five patients with HIE who did not have skin manifestations (4.6 +/- 1.1 micrograms/24 hr; p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
