The dysfunctional skin barrier in eczema patients may be attributed to decreased levels of ceramides in the stratum corneum. The aim of this study was to determine whether a two-part system consisting of a ceramide-dominant physiological lipid-based moisturizing cream and cleanser could ameliorate the signs and symptoms of moderate eczema in adults over 28 days compared to placebo. Assessments were conducted at baseline and every 7 days thereafter. Eczema area severity index score decreased significantly across all time points in both groups compared to baseline (P < .0001), however, this decrease was not significant between groups at day 28 (P = .7804). In contrast, transepidermal water loss and skin hydration significantly improved over time in the active group, while it either stayed the same or worsened in the placebo group (P = .0342 and P < .0001, respectively). There was no difference in the use of mometasone furoate as rescue medication over time between groups (P = .1579). Dermatology life quality index scores improved significantly in both groups (P < .0001), with no difference between groups (P = .5256). However, patient satisfaction was greater in the active compared to the placebo group for several parameters including relief of itch, dry skin, skin softness and smoothness (all P < .05). No patients withdrew from the study due to adverse events (AEs) and there were no serious AEs. The ceramide-dominant moisturizing cream and cleanser safely restores skin permeability and improves the signs and symptoms of eczema in adults.
特应性皮炎患者的皮肤屏障功能障碍可能与角质层神经酰胺水平降低有关。本研究旨在确定由含有较多神经酰胺的生理性脂质基础保湿霜和清洁剂组成的两部分系统是否可以在 28 天内改善 28 岁以上成年人中度特应性皮炎的体征和症状,与安慰剂相比。在基线和此后的每 7 天进行评估。与基线相比,两组在所有时间点的特应性皮炎面积严重程度指数评分均显著下降(P<0.0001),但在第 28 天两组之间的下降无显著差异(P=0.7804)。相比之下,在活性组中,经皮水分丢失和皮肤水分含量随着时间的推移显著改善,而在安慰剂组中,经皮水分丢失和皮肤水分含量要么保持不变,要么恶化(P=0.0342 和 P<0.0001)。两组之间在不同时间点使用莫米松糠酸酯作为急救药物的情况无差异(P=0.1579)。两组的皮肤病生活质量指数评分均显著改善(P<0.0001),两组之间无差异(P=0.5256)。然而,与安慰剂组相比,活性组在缓解瘙痒、干燥皮肤、皮肤柔软度和光滑度等几个参数方面的患者满意度更高(所有 P<0.05)。无患者因不良事件(AE)退出研究,也无严重 AE。含有较多神经酰胺的保湿霜和清洁剂可安全恢复皮肤通透性,并改善成年人特应性皮炎的体征和症状。
