2020年8月15日Lancet研究精选

【1】重组腺病毒新冠肺炎疫苗I期临床获得成功
 
 
近日研究人员评估了重组腺病毒5型(AD5) COVID-19疫苗的安全性、耐受性和免疫原性。
 
本次研究在武汉进行,为AD5Vectored Covid-19疫苗的剂量递增I期试验。 年龄在18至60岁之间的健康成年人随机接受5×1010, 1×1011或1.5×1011病毒颗粒剂量疫苗肌肉注射。 研究的主要结果是接种后7天的不良事件。接种后28天内对安全性进行评估,采用ELISA测定特异性抗体,以及疫苗接种引起的中和抗体反应。
 
2020年3月16-27日期间,108名志愿者参与研究,参与者中男性占51%,平均年龄36.3岁,其中低剂量组36人,中等剂量组36人,高剂量组36人。低剂量组30名参与者(83%)在疫苗注射后前7天报告了不良事件,中等及高剂量组分别为83%和75%。最常见的注射部位不良事件为疼痛,54%的患者报告存在疼痛,最常见的系统性不良事件为发热(46%)、疲劳(44%)、头痛(39%)和肌肉痛(17%)。所有剂量组的不良事件较为温和,在注射后28天未发生严重不良事件。ELISA抗体及中和抗体检测发现,在疫苗注射后14天,抗体含量显著增加,在28天达到顶峰,在疫苗注射后14天特异性T细胞响应达到顶峰。
 
【2】AZD1222腺病毒载体新冠疫苗(ChAdOx1)安全性及免疫性研究
 
 
近日英国研究人员进行的AZD1222腺病毒载体疫苗(ChAdOx1)1/2期临床实验。
 
共有1077名参与者分别接受了ChAdOx1 nCoV-19(n = 543)以及对照脑膜炎球菌结合疫苗MenACWY(n = 534)的接种。参与者的平均年龄为35岁,90%以上的参与者为白种人。
 
在ChAdOx1 nCoV-19组中,抗SARS-CoV-2穗蛋白抗体在第28天达到峰值,并在接种后的第56天里仍然保持高水平。研究人员从多个维度评估了参与者体内的中和抗体水平:采用PRNT50分析方法,研究人员对35名受试者进行血清中和检测,发现所有参与者均获得了中和效价,中位滴度为218;采用MNA80法检测,91%在单次接种后具有血清中和反应,而应用则100%具有血清中和反应。采用特异性干扰素γ酶联免疫斑点测定T细胞免疫反应,接种ChAdOx1-nCoV-19第7天出现细胞免疫反应,并且第14天特异性T应答达到峰值,直至第56天仍绕保持在较高的水平。ChAdOx1-nCoV-19组不良反应包括注射部位疼痛、头痛、疲劳、发冷、发热、不适和肌肉疼痛等,未报告严重不良事件。
 
【3】童年不良经历增加成年后早亡风险
 
 
儿童期是大脑和生理迅速发育的敏感期,儿童期遭遇变故可能干扰这一过程,对健康产生长期影响。近日研究人员就儿童时期经历,与成人早期的总体和特定原因死亡率之间的关系进行了考察。
 
研究将参与者童年逆境的3个不同方向:贫困和物质匮乏、失去亲人或亲人重大疾病威胁以及家庭变动(如寄养、与母亲分离)总计1097628名儿童纳入本次研究,将童年逆境分为5个水平,与经历较少逆境的儿童相比,那些儿童期物质匮乏 (危险比:1.38)、长期处于物质匮乏(1.77)或失去亲人(1.8)儿童的过早死亡风险相对较高。一小部分儿童(36081[3%])在所有方向和整个童年始终处于多重逆境,其全因死亡风险是低逆境儿童的4.54倍,相当于每10000随访年额外导致10.30人死亡。事故、自杀和癌症是这一高逆境人群中最常见的死亡原因。
