Am J Respir Crit Care Med:帕利珠单抗预防早产儿和随后复发性喘息:6年随访研究

2017-02-15 MedSci MedSci原创

呼吸道合胞病毒(RSV)不仅可导致婴儿反复喘息,而且可能诱发潜在的特应性哮喘。

呼吸道合胞病毒(RSV)不仅可导致婴儿反复喘息,而且可能诱发潜在的特应性哮喘。

为了验证RSV感染对随后的特应性哮喘发展的影响,我们评估了帕利珠单抗(一种抗RSV单克隆抗体)是否通过预防1岁内重度RSV疾病,从而影响随后6年内复发性喘息和特应性哮喘的发生发展。

在2007 - 2008年RSV感染高发季节,根据标准的医疗操作规程予以帕利珠单抗,对孕龄33至35周的早产儿(n = 52)进行一项6年的观察性前瞻性多中心病例对照研究。研究对象的父母通过使用报告卡和一种新型手机(基于互联网的报表系统)报告婴儿复发性喘息评估结果。主要终点是特应性哮喘的发病率。

444名早产儿入选,349人在1岁内接受帕利珠单抗治疗。然而在6岁时,治疗组(15.3%)和非治疗组(18.2%)之间特应性哮喘没有差异(p = 0.57)。而在治疗组和未治疗组中,医生诊断的复发性喘息分别为15.3%和31.6%(p = 0.003)。

给予早产儿帕利珠单抗预防不能抑制特应性哮喘的发生,但可明显降低6岁内复发性喘息的发生率。

哮喘的早期识别与早期干预

早期识别目前对于学龄前喘息儿童很难做出哮喘的确定诊断,但由于80%以上的哮喘起始于3岁前,学龄前期即开始出现肺功能损害,因此,从学龄前喘息儿童中识别出可能发展为持续性哮喘的患儿是很必要的。研究表明,与未患喘息的对照组儿童相比,确诊的喘息患儿支气管上皮网状基底膜明显增厚,且可检测到嗜酸性粒细胞,表明在喘息患儿中已存在气道重塑和炎症反应。如果喘息患儿不进行早期干预,可导致成年期肺功能降低和哮喘风险增高
