简介:背景:Behcet病(BD)患者最常见的临床表现是口腔黏膜和生殖器皮肤/黏膜的复发性疼痛溃疡,会影响患者的生活质量。由于粒细胞集落刺激因子(G-CSF)在创伤愈合中的有效性,它可能对治疗BD的口腔溃疡(OU)和生殖器溃疡(GU)有效。目的:旨在确定局部外用G-CSF治疗BD的OU和GU的有效性。方法:根据Behcet病国际研究小组的标准诊断为BD的7例患者纳入本研究。参与研究治疗前对患者进行3个月的观察,记录在此期间的所有发病情况。此后给予患者局部OU外用G-CSF4×120μg/d,连用5d,和(或)GU4×30μg/d,连用5d,治疗后随访3个月。研究期间全部患者未使用并发的疾病特异性药物或免疫抑制性的外用或系统药物。结果:对比之前接受的治疗,7例用G-CSF治疗的患者中,有6例创面愈合时间降低了,并减少了OU和GU的疼痛。但治疗后一段时间,G-CSF在OU和GU的愈合时间和疼痛严重度的有效性并不持续。结论:G-CSF对BD患者的OU和GU的愈合时间和疼痛严重度的改善有积极作用。但鉴于G-CSF的费用高昂、制剂不实用,不能够治愈本病,因此G-CSF仅用于部分选择性患者的治疗。(1139~1143译)外用...
