Effect of 5-aminolevulinic acid photodynamic therapy on keratinocyte proliferation and apoptosis in condyloma acuminatum.(ALA-PDT對尖銳濕疣角質形成細胞增殖和凋亡的影響).Yin G, Sha K, Cai B, et al. Photodiagnosis Photodyn Ther. 2017;18:310-314.

內容提要:納入52例CA患者,檢測PDT治療前後CA組織中角質形成細胞相關的Ki-67水平及凋亡。結果顯示,PDT治療前後:Ki-67陽性率從84.62%降至42.31%,表達強度從++ - +++降至- - ++,增殖指數從80.26±5.07%降至42.67±3.06%;凋亡指數從13.94 ± 2.35%上升至73.88 ± 7.65%,表達強度從+ ? ++上升至++ ? +++。

Two-step irradiance schedule versus single-dose cold compress for pain control during 5-aminolevulinic acid-based photodynamic therapy of condyloma acuminatum.(二步照光法 vs 冷敷PDT治療中疼痛的控制效果的對比)Shao X, Wang F, Xu B. Lasers Surg Med. 2017 Jun 22. doi: 10.1002/lsm.22699.

內容提要:141例ALA-PDT治療的CA患者隨機接受二步照光法或冷敷以止痛,結果顯示二步照光法NRS評分更低,提示其止痛效果更好。

淺表性基底細胞癌

Photodynamic therapy with epidermal ablation using fractional CO2 laser for treating superficial basal cell carcinoma: A case series(點陣CO2激光剝脫聯合PDT治療sBCC系列病例報道).Sung JM, Kim YC. Photodiagnosis Photodyn Ther. 2017 Jun 21. doi: 10.1016/j.pdpdt.2017.06.009.

內容提要:3例sBCC,且不願手術的患者,接受PDT治療。每次治療前採用點陣CO2激光剝脫,後外敷MAL,630nm照射37J/cm2。在3-5次治療後,均得到完全緩解。

硬化性苔癬

ALA-Photodynamic treatment in Lichen sclerosus-clinical and immunological outcome focusing on the assesment of antinuclear antibodies(ALA-PDT對硬化性苔蘚的臨床療效和免疫學結果的影響). Olejek A, Gabriel I, Bilska-Janosik A, et al, Gracia-Caza?a T, González S, Juarranz A, Gilaberte Y. Photodiagnosis Photodyn Ther. 2017 Jun;18:128-132.

內容提要:納入100例門診常規治療無效的LS患者,其中40伴有自身免疫疾病。患者均接受10次ALA-PDT治療後,51%癥狀完全消失,41%癥狀減輕,8%穩定或惡化。在伴有自身免疫疾病的患者中,PDT治療後,抗核抗體的水平顯著降低。

銀屑病

Systemic ALA-PDT effectively blocks the development of psoriasis-like lesions and alleviates leucocyte infiltration in the K14-VEGF transgenic mouse (系統ALA-PDT治療抑制銀屑病模型小鼠的皮損進展並減輕淋巴細胞浸潤). Chen T, Zhang LW, Fu LX. et al, Photodiagnosis Photodyn Ther. 2017 May 11. doi: 10.1016/j.pdpdt.2017.05.006.

內容提要:系統性ALA-PDT治療可抑制銀屑病模型小鼠(K14-VEGF轉基因小鼠)的銀屑病樣皮損的發展,並減少皮損中的T細胞, CD11c+ DCs和中性粒細胞浸潤,降低炎性細胞因子IL-17盒IFN-γ的水平。

汗孔角化症

Porokeratosis ptychotropica responding to photodynamic therapy: An alternative treatment for a refractory disease(PDT對汗孔角化症ptychotropica的療效). Fustà-Novell X, Podlipnik S, Combalia A, et al., Photodermatol Photoimmunol Photomed. 2017 Jun 5.
