　　要津词：慢性收敛性肺疾病；从不抽烟者；系统综述；东谈主口特征

　　一、

　　本系统综述的先容

　　刻下，慢性收敛性肺疾病(COPD)已成为环球第三大死因。在COPD的诱因中，天然抽烟是一个要津的环境危急成分，但现在仍是封锁到，宇宙上约30%的COPD病例发生在从不抽烟者 (NS) 中。然则，对于NS-COPD（从不抽烟者中的COPD）的流行病学、天然病史和临床特征尚不清澈。事实上，现在险些莫得任何专诚针对NS-COPD患者的接洽。

　　现存信息来自于对大型抽烟有关COPD部队中NS-COPD患者亚组的分析。基于这些零碎的不雅察，总结以为NS-COPD多发于年青女性，呼吸系统症状较轻，呼吸盘算相同，但孤寒谈梗阻较严重，肺气肿较少，肺功能随时期的下跌率较低，袪除症发生率较低。从生物学角度看，NS-COPD患者痰中中性粒细胞减少，嗜酸性粒细胞增多，巨噬细胞吞吃功能相等。

　　为进一步封锁NS-COPD，在这里，咱们对有关文件进行了系统转头。

　　二、

　　检索计策、纳排尺度和质料评估

　　在PubMed (Medline) 和Embase数据库中进行文件检索，使用了以下解放文本的不同组合；MeSH术语和布尔运算符: chronic obstructive pulmonary disease; chronic airflowobstruction; chronic airflow limitation; AND non-smokers OR never-smokers。检索时期设定在2000年1月1日至2022年12月31日。

　　纳入尺度: (a) 妥贴条目的接洽想象包括部队接洽、病例对照接洽和横断面接洽; (b) 接洽东谈主群年齿必须在18岁或以上，包括男性和女性，最小样本量为100名参与者，其中至少有20名患有COPD且从不抽烟; (c) 摈斥未提供从不抽烟者服从分类的接洽; (d) COPD的会诊必须基于临床症状和支气管膨胀剂后FEV1/FVC <0.70的客不雅肺活量测定说明。完成进一步筛查，剔除不妥贴要求的文件后最终获得17篇论文，实验经由如图1所示。

　　接纳以下尺度进行评估:样本量;NS-COPD病例数;接洽想象; COPD的会诊，每个名堂的得分从0到2，其中0为最低得分，8为总体最高得分 (如表1)。

　　图1 本接洽纳入论文的聘用经由 (PubMed, Embase, 2000-2022)

　　表1 对所纳入名堂进行的质料评定

　　COPD：慢性收敛性肺疾病；NS-COPD:从不抽烟者中的COPD；FEV1：第一秒用劲呼气容积；FVC：用劲肺活量；PBD：欺骗支气管膨胀剂后

　　三、

　　服从及分析

　　纳入的17项妥贴上述纳入/摈斥尺度的接洽中：接洽的质料从2分（最小值）到6分（最大值），平均值为3.4分，标明合座质料为中-低质料。从患病率、严重进度、性别、年齿、症状等方面进行考虑分析，不错发现不同接洽间存在的表露异质性。

　　从症状上讲，NS-COPD患者多量推崇为轻度至中度气流受限，对应于GOLD品级1级和2级；纳入接洽中NS-COPD的性别有关论断异质性很强，有7项接洽偏向于女性发病率大于男性，有5项接洽以为男性发病率是女性的3倍以上；8项接洽以为NS-COPD倾向于年齿较大，中重度NS-COPD患病率跟着年齿的增长而显耀加多，然则，在其他接洽中，未不雅察到NS-COPD和S-COPD受试者之间存在表露的年齿有关相反；此外，一些接洽一致以为，与S-COPD组比拟，NS-COPD组呼吸谈症状(慢性咳嗽、咳痰、呼吸穷困和喘气)的患病率较低，比拟之下三份接洽敷陈了更多的症状 (用劲时呼吸穷困、慢性坐蓐性咳嗽和喘气)、更大的膂力行径放置、更差的疾病适度、更低的氧足够度和更高的就诊次数。

　　四、

　　结  语

　　这是第一个分析NS-COPD会诊过火进展的临床特征的系统综述。本综述使用了专诚为天职析想象的质料量表，然则，必须承认仍然存在一些潜在的放置，NS-COPD患者的样本量通常较小，通常来自于较大的COPD患者部队的一部分，并莫得证据接洽的质料专诚想象的病例对照接洽来细则抽烟者与不抽烟者的病因或特征，也穷乏旨在不雅察COPD抽烟者与不抽烟者在其他临床服从方面是否存在相反的随访接洽。

　　笔者团队接洽数据骄贵（中国全科医学，已接管，待发表），接洽纳入NS-COPD患者中，女性42例，占80.8%（样本量较小，可扩大样本量后进一步接洽），60岁以上NS-COPD患者47例，占89.4%，S-COPD与NS-COPD患者氧足够度并莫得显耀相反（P=0.565）；海外接洽中NS-COPD在不同性别散布接洽服从相反较大，海外接洽与笔者数据均骄贵NS-COPD中支气管炎型COPD多于肺气肿型COPD。

　　而现在咱们对于NS-COPD的学问严重穷乏，本系统综述中纳入的不同接洽具有高度的异质性，紧迫需要想象高超的接洽来访问其临床特征和疾病天然史，况且鉴于好多发达国度抽烟率下跌的趋势，这少许尤其要紧。
