Histologic responses in human skin test reactions to ragweed. IV. Effects of a single intravenous injection of steroids

A controlled study has been carried out dealing with the early effects of a single intravenous dose of either methylprednisolone or placebo or newly developed and ongoing cellular inflammatory responses in immediate hypersensitivity skin test reactions. There was no significant difference in the tissue eosinophil responses to ragweed injected 2 hr before and 2 hr after placebo; there was a significant rise (101% +/- 39) from the second to fourth hour after antigen injection. By contrast, there was a marked decrease in the tissue eosinophil response to antigen injected 2 hr after steroids as compared to the pattern seen in the presteroid reaction. In addition, the eosinophil numbers not only did not increase from the second to fourth hour when steroids were injected at the second hour but decreased markedly. These findings suggest early suppressive effects on tissue eosinophil responses within 2 hr after steroid were administered intravenously. Also, there may be trafficking of eosinophils both into and out of these inflammatory sites during the first hours after intradermal antigen injection.

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.
