Br J Dermatol:柠檬酸治疗难治性感染性静脉湿疹

2021-11-16 医路坦克 MedSci原创

静脉曲张继发的皮肤问题通常是由于瘀血而发生的。柠檬酸用于治疗感染性静脉性湿疹并取得积极效果的报道尚属首次,这将为研究这种安全和经济有效的方法治疗感染性静脉湿疹开辟新的途径。

     静脉曲张继发的皮肤问题通常是由于瘀血而发生的。主要的治疗方法仍然是中和淤滞或适当的外科治疗,以及各种药物和润肤剂的应用。感染/渗出性湿疹具有挑战性,需要精细平衡不同的局部治疗。但难治性感染性湿疹仍然是生活质量受损的原因。

     该文报告一例静脉曲张合并难治性湿疹的手术病例,然后用柠檬酸利卡因软膏治疗。患者男,38岁,有大隐静脉曲张、隐股交界处功能不全、多支穿支功能不全和左下肢静脉水肿的病史。患者接受了静脉内激光消融和硬化治疗,随后水肿逐渐发展为左腿内侧表面的渗出性湿疹。对于他的湿疹,在两到三个月的时间里,患者接受了不同的外用类固醇(莫美松)、润肤剂(含有芦荟、马蹄、维生素E和其他保湿剂的乳膏和乳液)和外用抗生素(夫西迪酸)治疗瘙痒和感染的组合。同时也使用高锰酸钾沐浴。同时开出剂量递减的羟苯磺酸钙、抗组胺药和口服类固醇。尽管如此,湿疹仍然存在,没有任何改善(图1a)。当病人出现在我们面前时,没有任何感觉-运动或动脉缺陷,也没有任何下肢畸形。脓液培养发现耐甲氧西林的金黄色葡萄球菌对亚胺培南和美罗培南敏感。

     彻底清洗伤口,清除松散结痂后,发现约5 cm×7 cm的不规则浅表溃疡,肉芽变浅。经患者同意,决定使用柠檬酸。该软膏是将3克柠檬酸加入30克2%利多卡因凝胶和70克100%纯凡士林凝胶剂中研磨而成。每日用药前先用生理盐水冲洗、清洁肢体,然后涂抹柠檬酸软膏,创面轻压包扎。经过六次应用,他的不适和瘙痒已经消退,结痂也已经干燥,明显的改善鼓励我们继续应用(图1b)。在20次治疗之后,观察到进一步显著的改善(图1c)。经过60次治疗,湿疹完全消退,溃疡愈合,没有残留静脉水肿(图1D)。重复拭子培养无菌,未发现耐甲氧西林金黄色葡萄球菌对亚胺培南和美罗培南敏感。

 

文献检索未发现有关柠檬酸治疗湿疹患者的相关数据。据我们所知,柠檬酸用于治疗感染性静脉性湿疹并取得积极效果的报道尚属首次。我们提出了这项新技术,这将为研究这种安全和经济有效的方法治疗感染性静脉湿疹开辟新的途径,这是传统方法所不能比拟的。
