Corticosteroid-Induced Cutaneous Atrophy and Telangiectasia

Abstract

A bioassay for the evaluation of certain adverse effects of various corticosteroids was performed. Twenty-eight daily topical applications of corticosteroids to young rats produced reduction in body-weight gain, atrophy of the skin as determined by double skin-fold thickness micrometer measurement, and mild to severe telangiectasia. This animal model demonstrates corticosteroid-induced skin atrophy and telangiectasia and the correlation of the degree of atrophy and telangiectasia to body-weight change. Nine corticosteroids were evaluated by this method and are listed in terms of increasing severity of side-effects as follows: 1.0% hydrocortisone cream, 0.1% betamethasone valerate cream, 0.025% betamethasone benzoate cream, 0.05% flurandrenolide cream, 0.05% fluocinonide cream, 0.1% dexamethasone cream, and 0.03% flumethasone pivalate cream. Triamcinolone acetonide cream, 0.5%, and 0.2% fluocinolone acetonide cream resulted in death of the animals prior to completion of 28 days of topical application.
