We compared the cutaneous reaction to intradermal injection of substance P, gastrin and histamine in asymptomatic atopic subjects with a history of hay fever and/or asthma versus non-atopic healthy volunteers. We also studied in these two groups the basophilic histamine release induced by substance P and gastrin with that obtained with anti-human IgE and Con A. Intradermal injection of substance P (3-300 pM) and gastrin (3-30 pM) caused a wheal and flare reaction which was comparable in both groups of subjects. Substance P 10(-4)M caused a mean basophilic histamine release of about 15% in atopic and non-atopic subjects. Gastrin was not effective in this model. Anti-IgE and Con A-induced histamine release was significantly higher in atopic than in non-atopic volunteers.

Physiologic concentrations of human gastrin I (G17) and a synthetic analog of the carboxy-terminal region of gastrin, pentagastrin, provoked a dose-related release of histamine from human cutaneous mast cells in vitro. The N-terminal tridecapeptide portion of gastrin (G1-13) neither stimulated histamine release nor blocked the action of G17. In vivo correlation studies demonstrated that low concentrations (10(-12)M to 10(-10)M) of G17 or pentagastrin administered intradermally provoked a modest but definite wheal-and-flare response in four out of six normal subjects and a more marked, dose-related response in a patient with mastocytosis. These results indicate that physiologic concentrations of gastrin can stimulate mediator release from human cutaneous mast cells. We propose that this response may be mediated through receptors recognizing the carboxy-terminal region of the gastrin molecule. The possible role of gastrin-induced human mast cell-mediator release should be considered in the assessment of allergic disorders and in experimental models investigating mast cell function.
