Crisaborole 2% ointment is a non-steroidal treatment for mild-moderate atopic dermatitis (AD) and may produce fewer adverse effects than topical corticosteroids (TCS). We used PS-OCT to quantify dermal collagen at baseline and after 29 days of treatment with crisaborole and betamethasone valerate (BMV), in 32 subjects. PS-OCT detected a mean increase 1 × 10-6, 95% CI (6.3, 1.37) × 10-6 in dermal birefringence following TCS use (p < 0.0001, ad-hoc, not powered), whereas a change of -4 × 10-6, 95% CI (-32, 24) × 10-6 was detected for crisaborole (p = 0.77, ad-hoc, not powered). These results could suggest a differential effect on dermal collagen between the two compounds. PS-OCT may thus find an important role in safety assessment of novel AD treatment' and larger trials are warranted.
2%克立硼罗软膏是一种用于治疗轻中度特应性皮炎（AD）的非甾体药物，与外用糖皮质激素（TCS）相比，其产生的不良反应可能更少。我们使用偏振敏感光学相干断层扫描（PS-OCT）对32名受试者在基线时以及使用克立硼罗和戊酸倍他米松（BMV）治疗29天后的真皮胶原蛋白进行定量分析。PS-OCT检测到使用TCS后真皮双折射平均增加1×10⁻⁶，95%置信区间（6.3，1.37）×10⁻⁶（p<0.0001，临时分析，未计算效能），而克立硼罗组检测到的变化为-4×10⁻⁶，95%置信区间（-32，24）×10⁻⁶（p=0.77，临时分析，未计算效能）。这些结果可能表明这两种化合物对真皮胶原蛋白的作用存在差异。因此，PS-OCT可能在新型AD治疗的安全性评估中发挥重要作用，有必要开展更大规模的试验。
