《柳叶刀》对曹彬、张定宇等“6个月新冠长期症状”论文发布关注声明,作者称数据集中变量顺序错误

澎湃新闻报道,2022 年 11 月 24 日,《柳叶刀》(The Lancet)编辑部对曹彬等人的一篇研究论文发表关注声明(expression of concern)。该论文标题为《新冠肺炎出院患者的6个月临床结局:一项队列研究》(6-month consequences of COVID-19 in patients discharged from hospital: a cohort study,以下简称“6 个月论文”),于 2021 年 1 月 8 日在线发表在《柳叶刀》上,披露了对 2020 年 1 月至 5 月自武汉市金银潭医院出院的 1733 例患者集中随访的研究结果,发现 76% 的患者报告,发病后 6 个月仍存在至少一项长期症状。论文标明曹彬、张定宇和王健伟贡献相同,曹彬为通讯作者。

2021 年 8 月,曹彬、王健伟等人在《柳叶刀》发表了《新冠肺炎住院幸存者的1年临床结局:一项纵向队列研究》(1-year outcomes in hospital survivors with COVID-19: a longitudinal cohort study,以下简称“1 年论文”),表示还存在至少一种长期症状的患者比例从 6 个月时的 68% 下降到 12 个月时的 49%。

关注声明称,“1 年论文”发表后,《柳叶刀》收到了研究者关于两篇论文数据不一致的询问(6 个月时还存在长期症状的患者比例不同),并向两篇论文的通讯作者寻求解释,随后编辑部被告知,“6 个月”和“1 年”论文数据间的不一致,是由于“用于 6 个月论文的数据集中的一些变量被错误地打乱了顺序”。编辑部表示,“鉴于这些数据错误的程度,我们现在对‘6个月’论文发表关注声明,同时将进一步调查,包括对更正后数据的进一步统计和临床审查。”

此外,2022年 5 月 11 日,曹彬和王健伟作为共同通讯作者,在《柳叶刀-呼吸病学》(The Lancet Respiratory Medicine)发表了对新冠肺炎出院患者中 1192 人随访两年的研究结果,论文显示“还存在至少一种长期症状的患者从 6 个月时的 68% 显著下降到 2 年时的 55%。”该研究被报道为“全球新冠最长随访”。(澎湃新闻)

寒冷天气为何更易发生上呼吸道感染

秋冬季节,人们普遍更容易感染新冠、流感、感冒等呼吸道病毒疾病。此前的一些研究认为,是因为冬季人们待在室内的时间更长,有利于病毒的传播。但最近的一项研究显示,鼻腔中存在一种抵御上呼吸道病毒感染的新型免疫应答机制。这一机制在低温下被抑制,可能解释了为何天冷时更容易发生上呼吸道感染。

研究者发现,鼻腔前端的细胞能通过释放外泌体抵御病毒的感染,随后,他们进一步测试了温度对这种反应的影响。结果显示,当志愿者从室温环境进入 4.4° C 的低温下 15 分钟后,他们鼻腔内部的温度下降了大约 5 ℃,这会导致鼻腔细胞产生的外泌体减少约 42%,且外泌体中的抗病毒蛋白数量也下降了。论文指出,这项研究发现了一种全新的免疫机制,未来可基于这一机制开发更有针对性的抗上呼吸道感染药物。相关研究 12 月 6 日发表于《过敏与临床免疫学杂志》(Journal of Allergy and Clinical Immunology)。(Massachusetts Eye and Ear Infirmary)
