A proportion of dermatophyte infections fail to respond to normally adequate courses of griseofulvin and topical antifungal therapy. The organism Trichophyton rubrum was isolated from 96% of 50 patients studied, but no instances of in vitro resistance were seen. Of these patients, 57% had an underlying condition, commonly hay fever/asthma, atopic eczema, collagen disease or ichthyosis. Defective delayed type hypersensitivity responses and leucocyte migration inhibition to the specific antigen, trichophytin, were demonstrated. Immediate type hypersensitivity was seen in 58% and this was partially suppressible with chlorpheniramine and cimetidine. The relationship between these abnormalities and failure of treatment is discussed.
一部分皮肤癣菌感染对通常足够疗程的灰黄霉素和局部抗真菌治疗无反应。从50例研究患者中的96%分离出红色毛癣菌,但未发现体外耐药情况。这些患者中,57%有基础疾病,常见的有花粉症/哮喘、特应性湿疹、胶原病或鱼鳞病。已证实存在对特异性抗原癣菌素的迟发型超敏反应缺陷和白细胞迁移抑制。58%的患者出现速发型超敏反应,且可用氯苯那敏和西咪替丁部分抑制。讨论了这些异常与治疗失败之间的关系。
