異位性皮膚炎(濕疹): 實證治療
治療以階梯方式進行,而且每一級都保留下一級的基礎。潤膚劑從不停用。

第四級: 傳統系統性治療
適用於上述治療仍不足夠的中重度病情,所有藥物均需基線及持續的血液監察。
- 環孢素:起效最快,通常 2 至 6 週內即有明顯改善。因對血壓及腎功能的影響,一般作短期使用(通常不超過 6 至 12 個月)。用於挽救嚴重發作極為有效。
- 甲氨蝶呤:起效較慢,較適合長期使用,每週一次,一般耐受良好。
- 硫唑嘌呤:開始前須檢測 TPMT。
- 霉酚酸酯:上述藥物不適用時的替代選擇。
口服類固醇需要特別警告: 它見效極快,因此十分誘人,但濕疹在停藥後往往反彈得比原先更嚴重。
***它只適合在嚴重發作時作短暫過渡,絕不應作持續治療。若患者反覆接受口服類固醇療程,這個模式本身就值得檢討。***
第一級治療: 外用抗炎治療
第二級治療: 主動維持治療(常被忽略)
第三級治療: 窄頻NB-UVB 光療
第四級治療: 傳統系統性治療
第五級治療: 生物製劑, 口服JAK抑制劑
