The purpose of this study is to investigate in humans three iodine thyroacetic acid (TRIAC) and dehydroepiandrosterone (DHEA) combination effect on corticosteroid induced collagen synthesis effect compared with the single TRIAC, DHEA or placebo. 6 the median age was 40 65 year old healthy male volunteers participated in the study of human. The four abdominal skin area with betamethasone valerate cream pretreatment for 3 weeks. Then, the same areas were treated with one of the following alternatives in the same cream medium: 2 weeks: TRIAC, DHEA, TRIAC+DHEA, and placebo. A vacuum pump is then used to produce a sucking blister in each of these areas. Collect blister fluid from each area and freeze until analyzed. Sucking blisters in human type I collagen (PINP) can purchase the immune assay kit is used to analyze the amino terminal propeptide (Orion Diagnostics) to. This is the first study to show a combination of TRIAC and DHEA in the pretreatment of skin with betamethasone valerate effectively stimulate collagen synthesis by PINP, this increase was confirmed, and the combination is more effective than single TRIAC or DHEA. This combination may be effective in the treatment of corticosteroid induced atrophy of the skin. It can also be used to treat skin atrophy caused by other conditions, such as sunburn and skin atrophy caused by advanced age. Another interesting application is the combination of TRIAC and DHEA with potent corticosteroids to prevent corticosteroid induced skin atrophy. If this combination is still effective in the treatment of eczema and psoriasis and there is no risk of skin atrophy, this combination will be an important breakthrough in the use of corticosteroids for potent surfaces.
【技术实现步骤摘要】
【国外来华专利技术】使用三碘甲腺乙酸(TRIAC)和脱氢表雄酮(DHEA)的组合治疗皮肤萎缩
本专利技术涉及三碘甲腺乙酸(TRIAC)和脱氢表雄酮(DHEA)的组合在皮肤萎缩的治疗中的用途。所述TRIAC和DHEA的组合提供了出人意料的协同效应。
技术介绍
众所周知,使用皮质类固醇的表面治疗引起作为副作用的皮肤萎缩。然而,由强效皮质类固醇引起的皮肤萎缩的有效治疗目前尚不可用。皮肤萎缩涉及表皮和真皮厚度的降低、皮脂腺的退化、皮下脂肪的丧失和肌肉层萎缩。通常,这些变化可以在开始使用中至高效表面用皮质类固醇治疗后2至3周看到。受影响的区域通常是具有高渗透性的皮肤例如面部,但可能出现在进行皮质类固醇施用的任何区域。萎缩症也可能在施用低效皮质类固醇后看到,并且通常在治疗结束后逆转。然而,在许多病例中,萎缩症是不会逆转的永久表象。已经尝试了开发使用另一种药理学方法的皮质类固醇替代疗法,但到目前为止只有少数比皮质类固醇的抗炎活性更低的替代疗法可用。这些治疗方案由维生素A和D衍生物和钙调磷酸酶抑制剂例如他克莫司构成。本专利技术提供了TRIAC和DHEA的组合,其可用于有效治疗皮肤萎缩,例如由使用皮质类固醇或长期暴露于日光所诱导的皮肤萎缩。专利技术详述本专利技术涉及TRIAC和DHEA的组合在皮肤萎缩、尤其是由使用皮质类固醇或长期暴露于日光而诱导的皮肤萎缩的治疗中的用途。本专利技术还涉及包含TRIAC和DHEA的组合物。所述组合物被设计用于表面给药到皮肤。TRIAC和DHEA的组合显示出在皮肤萎缩的治疗中具有协同效应。TRIAC和DHEA的组合,也可用于或提供在与一种或多种皮质类固醇一起的组合 ...
