For patients who have previously undergone treatment with immunosuppressants, the frequency and severity of relapses during the treatment process, as well as the length of time required for recovery, are positively correlated with the type, dosage, intensity, and duration of both topical and systemic immunosuppressive agents previously used. For example, the more frequently and for a longer duration that topical corticosteroids are used, the larger the area of skin they are applied to, and the more potent they are, the longer the required recovery time, and the more frequent and severe the relapses will be. Additionally, skin affected by more frequent and prolonged use of topical corticosteroids will also recover more slowly. Furthermore, the skin at the site of the rash may become darker after it fades, and continued treatment is necessary until the skin returns to its original white color and smooth texture to achieve complete recovery.
The time to recovery is much longer and more unpredictable for patients with a history of immunosuppressant use. This is because the results are greatly influenced by the dosage and strength of the that immunosuppressant was prescribed previously. A retrospective observational study shown that the effectiveness of Tangs was inversely associated to prior immunosuppressants exposure (r = 0.9154): the complete clearance was achieved in 8 months (87.5%, 14 of 16) in non-immunosuppressants subjects; the wavelike evolution of psoriatic lesion appeared in prior immunosuppressants subjects, time required to recover is proportionate to the time immunosuppressants were used. Individual response to our herbal treatment may differ, these are individual observations recorded during clinic follow-up, not controlled outcome data, and they do not predict the course of any other patient. Psoriasis, eczema, vitiligo, urticaria are currently regarded in modern medicine as a chronic relapsing condition for which no cure is established. We make no claim that Tangs Herbal TCM medicine cures or prevents relapse.
对于曾经用过免疫抑制剂治疗过的患者而言,治疗过程中出现的反弹频率及其严重程度和整个疗程的治愈时间长短与患者以前外用和内服的免疫抑制剂的种类、剂量、强度和疗程成正相关,例如:皮质类固醇外用的越多,外用时间越长、涂抹的皮肤面积越大、皮质激素越强效,那么所需治愈的时间也就越长,反弹次数也越多,反弹程度也越大,外用激素越多的皮肤部位的皮疹也就消退越慢。而且皮疹消退后的皮肤原地也越黑,必需继续治疗直到皮疹消退后的皮肤出现白色,质地光滑为止,才是完全消退。
