Neurology:早期喘鸣发作可预测多系统萎缩患者生存情况

2016-10-04 xing.T MedSci原创

研究结果表明,早期的喘鸣发作是多系统萎缩患者生存期较短的独立预测因子,气管切开可以控制气管喘鸣,但会影响疾病病程。

多系统萎缩是成年期发病、散发性的神经系统变性疾病,临床表现为不同程度的自主神经功能障碍、对左旋多巴类药物反应不良的帕金森综合征、小脑性共济失调和锥体束征等症状。由于在起病时累及这三个系统的先后不同,所以造成的临床表现各不相同。


近日,神经病学领域权威杂志《neurology》上发表研究文章旨在评估多系统萎缩患者喘鸣的预测价值以及发病的潜伏期,并且探究治疗喘鸣对多系统萎缩的影响。

研究者回顾性确诊多系统萎缩患者,至少每年评估一次疾病进程,通过整夜多导睡眠图和视频明确患者喘鸣情况,收集患者从发病到死亡的生存数据,采用Kaplan Meier曲线计算生存率,通过单变量和多变量Cox回归分析确定预测因子。

研究共纳入136例多系统萎缩患者,研究结束是有113例患者死亡,42例患者被确诊为喘鸣,22例患者出现早期喘鸣发作。31例接受喘鸣治疗的患者,其中12例进行了气管切开术,另外19例患者接受持续气道正压通气。有喘鸣与无喘鸣的多系统萎缩患者总生存率没有差异,而早期喘鸣发作的患者比那些喘鸣症状出现较晚的患者预后差。在喘鸣患者的亚组中,早期喘鸣发作是不良的生存预后,喘鸣治疗与患者生存情况显著相关。Kaplan-Meier曲线并没有发现两种治疗之间的生存率存在显著差异,即使气管切开患者有病程延长的趋势。
