使用免疫抑制剂及血管扩张剂可能使合并肺动脉高压的狼疮患者获益———项观察性研究
目的:观察接受环磷酰胺治疗的狼疮患者肺动脉收缩压的变化。
方法:选择24例经心脏彩超证实的肺动脉收缩压升高(30mmHg)的狼疮患者,接受环磷酰胺或激素治疗,伴或不伴血管扩张剂。在治疗前、治疗6个月时评估临床特征及肺动脉收缩压。有应答者定义为:比基线时肺动脉收缩压下降15mmHg且伴随心功能的改善。
结果:11例(45.83%)患者反应良好,其平均肺动脉收缩压从基线时59.33mmHg至6个月末时降至43.29mmHg(P0.)。单独接受环磷酰胺治疗的4例患者,其平均肺动脉压从基线时的39.75mmHg至6个月末时降至34.4mmHg(P=0.04)。有应答者和无应答者,在基线时其肺动脉收缩压及疾病活动程度并无差异。有2例患者死亡。
结论:免疫抑制剂及血管扩张剂治疗6个月可改善狼疮合并肺动脉高压患者的肺动脉收缩压。
