摘要:目的:外周血管病变是系统性硬化病(SSc)的特征性改变,可以通过甲周毛细血管显微镜检查(NFC)及早发现。本研究旨在探究患者严重的NFC外周血管病变是否是SSc患者死亡的预测因子。方法:选取2001年6月到2009年7月之间行NFC的系统性硬化病患者135例。评估以下NFC参数:毛细血管数/毫米,缺血评分(得分从0到3分),扩张毛细血管和巨型毛细血管管袢数。单因素分析和多元回归分析死亡率与NFC和临床指标的相关性。结果:在分析期间(2010年8月),123例患者存活,12例死亡。单变量分析显示,男性、用力肺活量1.5的都显著增加SSc患者死亡风险。多变量分析显示,缺血评分>1.5是SSc患者死亡的唯一独立预测因素(危险比2.265)。缺血得分>1.5的患者1年、5年、10年生存率(分别为97%、86%和59%),而缺血得分≤1.5的患者生存率(分别为97%、97%、91%)低。(P=0.009对数秩检验)。结论:NFC缺血得分高于1.5是系统性硬化病患者死亡的独立预测因素。提示NFC可预测系统性硬化病患者的预后。
