Abstract

In a last decade, new types of skin manifestations have been recognized in atopic dermatitis especially in Japan. They are frequently observed in adult patients with atopic dermatitis after a long-standing steroid ointment and termed adult type-atopic dermatitis. To clarify whether topical glucocorticoid (GC) modulates cutaneous inflammatory reactions in addition to known anti-inflammatory effect, we have examined the effect of long-term application of topical GC on IgE-mediated murine cutaneous reactions. Fifty microlitres of diflucortolone valerate (1 mg/mL), prednisolone valerateacetate (3 mg/mL), or triamcinolone acetonide (1 mg/mL) were applied seven times on alternate day, to the flank skin of mice. On day 12 when mice received the seventh application of GC, each mouse was given an intravenous application of IgE anti-DNP antibody (PCA titre > x 2560) 1 h before the skin test with 0.15% DNFB in acetone:olive oil (4:1) on the right pinna. The left pinna was painted with a vehicle as a control. Increased ear thickness was measured at 1, 4, 24, 48 and 72 h to assess the augmentry effect of GC. Topical application of GC (50 microg diflucortolone valerate in ethanol) on the flank skin seven times on alternate days, augmented ex...Continue Reading

Anaphylaxis

Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death.

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.
