Objective To investigate whether the amino acid variation in the nonstructural protein of Severe Acute Respiratory Syndrome Coronavirus2 (SARS-CoV-2) is related to the severity of Corona Virus Disease 2019 (COVID-19). Methods The data obtained from the Global Shared Influenza Data Initiative (GISAID) database were analyzed, and the nonstructural protein amino acid mutations with high mutation rate in SARS-CoV-2 sequences were screened. The outcomes were divided into mild and severe diseases, and the chi-square test was used to compare the basic characteristics between the groups. The relationship between the mutations selected and the prognosis of the patients was analyzed. Results A total of 23 498 cases were included, including 11 444 males (48.70%) and 12 054 females (51.30%). The median age [MP25P75)] was 38 (26-53) years old. The severe infection rate of novel coronavirus in male was higher than that in female (χ2=226.564, P < 0.001). The severe infection rate of novel coronavirus increased with the increase of age (χ2=6 088.032, P < 0.001). The year of onset (χ2=1 604.070, P <0.001) and continent (χ2=4 520.240, P < 0.001) were significantly correlated with the severity of novel corona virus infection.Several amino acid variations in the SARS-CoV-2 gene group associated with the severity of novel corona virus’s sensitive dyeing were determined. NSP4_T492I (aOR=0.574, 95%CI: 0.487-0.676), NSP12_G671S (aOR=0.657, 95%CI: 0.458-0.941),NSP6_T77A (aOR=0.422, 95%CI: 0.235-0.759), and NSP3_P1228L (aOR=0.124, 95%CI: 0.080-0.190) were negatively correlated with novel coronavirus’s severe infection. NSP12_P323L (aOR=2.126, 95%CI: 1.531-2.953), NSP13_P77L (aOR=1.923, 95%CI: 1.115-2.369), and NSP14_A394V (aOR=20.486, 95%CI: 9.649-43.495) were positively correlated with novel coronavirus’s severe infection. Conclusion The amino acid variation of SARS-CoV-2 nonstructural protein may be related to the severity of COVID-19 virus infection, and it is necessary to screen several nonstructural protein amino acid variants which can be related to the severity of novel coronavirus infection.

目的 本研究旨在探讨严重急性呼吸综合征冠状病毒2型(severe acute respiratory syndrome corona coronavirus 2,SARS-CoV-2)非结构蛋白氨基酸变异是否与新型冠状病毒感染(corona virus disease 2019,COVID-19)疾病严重程度有关。方法 对全球共享流感数据倡议组织(GISAID)数据库得到的数据进行分析,筛选SARS-CoV-2序列中突变频率较高的非结构蛋白氨基酸突变。将患者结果分为轻症和重症,采用χ2检验比较组间基线特征,逻辑回归检验选择的突变与患者预后之间的关系。结果 共纳入数据23 498例,其中男性11 444例(48.70%),女性12 054例(51.30%),中位数年龄[MP25P75)]为38(26,53)岁。男性新冠病毒感染重症率高于女性(χ2=226.564,P<0.001);随着年龄增加(χ2=6 088.032,P<0.001),新冠病毒感染重症率增加。发病年份(χ2=1 604.070,P<0.001)、大洲(χ2=4 520.240,P<0.001)与新冠病毒感染严重程度显著相关。确定了SARS-CoV-2基因组中几种可能与新冠病毒感染严重程度相关的氨基酸变异,NSP4_T492I(aOR=0.574, 95%CI: 0.487~0.676)、NSP12_G671S(aOR=0.657, 95%CI: 0.458~0.941)、NSP6_T77A(aOR=0.422, 95%CI: 0.235~0.759)、NSP3_P1228L(aOR=0.124, 95%CI: 0.080~0.190)与新冠病毒感染重症呈负相关,而NSP12_P323L(aOR=2.126, 95%CI: 1.531~2.953)、NSP13_P77L(aOR=1.923, 95%CI: 1.115~2.369)、NSP14_A394V(aOR=20.486, 95%CI: 9.649~43.495)与新冠病毒感染重症呈正相关。结论 SARS-CoV-2非结构蛋白氨基酸变异可能与新冠病毒感染严重程度相关,需要进一步验证筛选可能与新冠病毒感染严重程度相关的非结构蛋白氨基酸变异。

目的 本研究旨在探讨严重急性呼吸综合征冠状病毒2型(severe acute respiratory syndrome corona coronavirus 2,SARS-CoV-2)非结构蛋白氨基酸变异是否与新型冠状病毒感染(corona virus disease 2019,COVID-19)疾病严重程度有关。方法 对全球共享流感数据倡议组织(GISAID)数据库得到的数据进行分析,筛选SARS-CoV-2序列中突变频率较高的非结构蛋白氨基酸突变。将患者结果分为轻症和重症,采用χ2检验比较组间基线特征,逻辑回归检验选择的突变与患者预后之间的关系。结果 共纳入数据23 498例,其中男性11 444例(48.70%),女性12 054例(51.30%),中位数年龄[MP25P75)]为38(26,53)岁。男性新冠病毒感染重症率高于女性(χ2=226.564,P<0.001);随着年龄增加(χ2=6 088.032,P<0.001),新冠病毒感染重症率增加。发病年份(χ2=1 604.070,P<0.001)、大洲(χ2=4 520.240,P<0.001)与新冠病毒感染严重程度显著相关。确定了SARS-CoV-2基因组中几种可能与新冠病毒感染严重程度相关的氨基酸变异,NSP4_T492I(aOR=0.574, 95%CI: 0.487~0.676)、NSP12_G671S(aOR=0.657, 95%CI: 0.458~0.941)、NSP6_T77A(aOR=0.422, 95%CI: 0.235~0.759)、NSP3_P1228L(aOR=0.124, 95%CI: 0.080~0.190)与新冠病毒感染重症呈负相关,而NSP12_P323L(aOR=2.126, 95%CI: 1.531~2.953)、NSP13_P77L(aOR=1.923, 95%CI: 1.115~2.369)、NSP14_A394V(aOR=20.486, 95%CI: 9.649~43.495)与新冠病毒感染重症呈正相关。结论 SARS-CoV-2非结构蛋白氨基酸变异可能与新冠病毒感染严重程度相关,需要进一步验证筛选可能与新冠病毒感染严重程度相关的非结构蛋白氨基酸变异。

Objective To investigate whether the amino acid variation in the nonstructural protein of Severe Acute Respiratory Syndrome Coronavirus2 (SARS-CoV-2) is related to the severity of Corona Virus Disease 2019 (COVID-19). Methods The data obtained from the Global Shared Influenza Data Initiative (GISAID) database were analyzed, and the nonstructural protein amino acid mutations with high mutation rate in SARS-CoV-2 sequences were screened. The outcomes were divided into mild and severe diseases, and the chi-square test was used to compare the basic characteristics between the groups. The relationship between the mutations selected and the prognosis of the patients was analyzed. Results A total of 23 498 cases were included, including 11 444 males (48.70%) and 12 054 females (51.30%). The median age [MP25P75)] was 38 (26-53) years old. The severe infection rate of novel coronavirus in male was higher than that in female (χ2=226.564, P < 0.001). The severe infection rate of novel coronavirus increased with the increase of age (χ2=6 088.032, P < 0.001). The year of onset (χ2=1 604.070, P <0.001) and continent (χ2=4 520.240, P < 0.001) were significantly correlated with the severity of novel corona virus infection.Several amino acid variations in the SARS-CoV-2 gene group associated with the severity of novel corona virus’s sensitive dyeing were determined. NSP4_T492I (aOR=0.574, 95%CI: 0.487-0.676), NSP12_G671S (aOR=0.657, 95%CI: 0.458-0.941),NSP6_T77A (aOR=0.422, 95%CI: 0.235-0.759), and NSP3_P1228L (aOR=0.124, 95%CI: 0.080-0.190) were negatively correlated with novel coronavirus’s severe infection. NSP12_P323L (aOR=2.126, 95%CI: 1.531-2.953), NSP13_P77L (aOR=1.923, 95%CI: 1.115-2.369), and NSP14_A394V (aOR=20.486, 95%CI: 9.649-43.495) were positively correlated with novel coronavirus’s severe infection. Conclusion The amino acid variation of SARS-CoV-2 nonstructural protein may be related to the severity of COVID-19 virus infection, and it is necessary to screen several nonstructural protein amino acid variants which can be related to the severity of novel coronavirus infection.

由严重急性呼吸综合征冠状病毒2型(severe acute respiratory syndrome corona coronavirus 2,SARS-CoV-2)引起的新型冠状病毒(corona virus disease 2019,COVID-19)感染于2019年12月首次被报道[1-2]。世界卫生组织(WHO)于2020年3月11日宣布新冠病毒感染为全球大流行。SARS-CoV-2是一种单链正链RNA病毒,属于β冠状病毒属,基因组约30 kb,编码4种结构蛋白、8种辅助蛋白和16种非结构蛋白(NSP1-NSP16),[1,3]。非结构蛋白由开放阅读框1a/1ab (ORF1a/1ab)编码产生,参与病毒复制和组装的各个环节[4-6]
新冠病毒感染的严重程度包括无症状感染、轻症到重症和死亡[2,7-8]。宿主易感性、病毒变异和环境共同决定了新冠病毒感染的病程[9-11]。识别与疾病严重程度相关的宿主和病毒因素将有助于指导医疗行为和改善患者预后[12]。有研究发现,年龄和性别可能与新冠病毒感染严重程度相关[13-18]。随着时间的推移,全球范围内出现越来越多具有遗传多样性的SARS-CoV-2变异[2,19-21]。部分研究认为病毒基因组变异与疾病严重程度无关[22-27]。也有研究认为虽然病毒基因组变异与疾病严重程度无关,但普遍关注的S蛋白D614G变异对疾病严重程度的影响在先前研究中结果不一致,认为变异可增加新冠病毒感染重症风险[28-30],而Esper等[31]认为含有D614G的变异与患者住院时的生存率增加相关。关于非结构蛋白氨基酸变异对新冠病毒感染的影响研究发现,NSP12_P32 3L[29-30,32]、NSP3_T1198K[32]、NSP3_S1197R[32]、NSP7_L71F[32]、NSP12_A97V[32]变异可增加新冠病毒感染重症风险[29-30,32],而NSP6_L37F[32-34]、NSP4_F308Y[32]、NSP9_L42F[31]可降低新冠病毒感染严重程度。对普遍认为比较保守的非结构蛋白在病毒遗传和进化过程中变异情况如何以及与疾病严重程度的关系如何,缺乏系统研究。
本研究通过对非结构蛋白中变异频率前15位的氨基酸变异进行研究,探索SARS-CoV-2氨基酸变异与新冠病毒感染严重程度之间的关系,对于评估SARS-CoV-2演变带来的风险具有重要意义。本研究旨在探讨SARS-CoV-2非结构蛋白氨基酸变异是否与新冠病毒感染严重程度有关。
从全球共享流感数据倡议组织(GISAID)数据库(https://www.gisaid.ORg)下载了2020年2月20日—2022年12月24日的SARS-CoV-2的基因组序列和新冠病毒感染患者临床数据集,选择Complete(序列长度>29 000 bp)、High coverage(序列中不明确的碱基数量小于1%)、Collection date complete(有明确收集日期)、w/Patient status(包含病人病情信息)”,宿主为人类。根据患者数据集,将所有存在信息缺失的样本排除。根据病人状态分组,排除病人状态为住院、出院、活着、有症状、未知等无法确定病人病情的患者;轻症组纳入:未住院、发烧、轻症、无症状;重症组纳入:死亡、重症监护室、严重、肺炎。数据收集及筛选过程见图1。利用数据库中现有的氨基酸变异数据,根据氨基酸变异频率排序,选择变异频率为前15位的非结构蛋白氨基酸变异,分析其与新冠病毒感染严重程度的关系。
采用χ2检验或Fisher精确检验比较组间基线特征。采用逻辑回归分析,计算粗比值比(OR)和校正比值比(aOR)及其95%置信区间,使用单变量逻辑回归分析前15位非结构蛋白氨基酸变异与新冠病毒感染严重程度的关系,单变量逻辑回归分析中P<0.1的变量纳入多变量逻辑回归分析。选择以下协变量纳入多变量对逻辑回归模型进行调整:年龄、性别、大洲、诊断年份、S蛋白变异、M蛋白变异、E蛋白变异、N蛋白变异。数据处理和分析采用SPSS 20.0版本。双侧检验水准α=0.05。
图1所示,截至2022年12月24日,在GISAID数据库中共发现符合条件病例237 121例,因病情不明确排除213 623例,共纳入23 498例,其中男性11 444例(48.70%),女性12 054例(51.30%);中位数年龄[MP25P75)]为38(26,53)岁;包括来自亚洲的2 658例,北美的10 445例,南美洲的1 757例,欧洲的7 774例,非洲地区的864例。根据病人疾病严重程度分组,轻症组17 566例,重症组5 932例。
表1显示轻症组与重症组的基线特征比较,χ2检验结果显示,不同性别和年龄的人新冠病毒感染严重程度差异有统计学意义(χ2=226.564,P<0.001),其中男性重症率高于女性;随着年龄增加,新冠病毒感染重症率增加(χ2=6 088.032,P<0.001),>75岁年龄阶段重症率最高。不同发病年份的新冠病毒感染重症率差异有统计学意义(χ2=1 604.070,P<0.001),与2020年新冠病毒相比,2021年新冠病毒感染重症率明显降低,2022年新冠病毒感染重症率最低。不同大洲发生的新冠病毒感染严重程度有明显差异(χ2=4 520.240,P<0.001),以非洲为对照,南美洲新冠病毒感染重症率最高,北美洲新冠病毒感染重症率最低。
与序列hCoV19/Wuhan/WIV04/2019相比,所有非结构蛋白氨基酸变异中突变频率前15位的氨基酸变异见表2,其中NSP12_P32 3L突变频率最高。单因素逻辑回归分析结果显示,NSP4_T492I、NSP12_G671S、NSP13_P77L、NSP6_T77A、NSP3_P1469S、NSP14_A394V、NSP4_V167L、NSP3_A488 S、NSP3_P1228L与新冠病毒感染严重程度有显著关联(P<0.05)。多因素逻辑回归模型1为未调整的多因素分析,结果显示NSP4_T492I、NSP13_P77L、NSP3_P1228L与新冠病毒感染重症呈负相关,而NSP12_G671S、NSP3_P1469S、NSP14_A394V与新冠病毒感染重症呈正相关。多因素逻辑回归模型2调整了可能的混杂因素,调整性别、年龄、确诊年份、大洲、S蛋白变异、M蛋白变异、E蛋白变异、N蛋白变异,结果显示NSP4_T492I、NSP12_G671S、NSP6_T77A、NSP3_P1228L与新冠病毒感染重症呈负相关,而NSP12_P323L、NSP13_P77L、NSP14_A394V与新冠病毒感染重症呈正相关。
感染新冠病毒后,大多数患者仅表现为轻症,但仍有患者出现严重临床表现,甚至死亡。关于氨基酸变异对新冠病毒感染严重程度的影响目前尚不明确,并且普遍认为比较保守的非结构蛋白在病毒遗传和进化过程中变异情况如何以及与疾病严重程度的关系如何,缺乏系统研究。本研究比较了轻症组与重症组基线数据并分析了突变频率排名前15位的非结构蛋白氨基酸变异与新冠病毒感染严重程度的相关性。结果表明男性重症风险高于女性,随着年龄增加,新冠病毒感染重症的风险增加,不同发病时间、不同大洲发生的新冠病毒感染严重程度有明显差异。研究发现了与新冠病毒感染重症相关的几种变异,NSP4_T492I、NSP12_G671S、NSP6_T77A、NSP3_P1228L与新冠病毒感染重症呈负相关,而NSP12_P323L、NSP13_P77L、NSP14_A394V与新冠病毒感染重症呈正相关,这些变异的功能意义还有待进一步研究。
研究发现,男性新冠病毒感染重症率高于女性,随着年龄增加,新冠病毒感染重症率增加,这与先前研究结果一致[13-18]。大量证据表明,高龄是严重新冠病毒感染的重要风险因素,可能是由于老年人免疫力下降[35-36]。本研究结果还发现不同发病时间的新冠病毒感染严重程度有明显差异,可能与不同时间流行的变异株不同有关,不同变异株可影响疾病严重程度[37-42]。不同大洲发生的新冠病毒感染严重程度有明显差异,不同大洲医疗资源、卫生经济条件不同,可能对疾病严重程度产生影响。
本研究发现NSP12_P323L、NSP13_P77L、NSP14_A39 4V与新冠病毒感染重症呈正相关。之前有研究认为NSP12_P323L变异与较高的病死率显著正相关[29-43],并且在重症病例中比在轻症病例中更常见[30],与我们的结果一致,这可能与其有助于病毒逃避宿主抗体介导的免疫反应有关[44]。 NSP13_P77L变异可增强NSP13与TANK结合激酶1(TBK1)的结合从而抑制IFN-β的产生以逃避宿主免疫系统[45],可能导致增加新冠病毒感染重症风险。有研究结果显示NSP14_A394V在免疫正常患者治疗后样本中更为常见,表明其可能与病毒耐药性增加有关[46]。本研究发现,NSP4_T492I、NSP12_G671S、NSP6_T77A、NSP3_P1228L与新冠病毒感染重症呈负相关。在先前有关研究中发现NSP4_T492I[47]、NSP12_G671S可以增加病毒的复制和有效传播[48]。还需进一步研究其在降低新冠病毒感染重症风险的作用。NSP6、NSP3在病毒复制中起到重要作用,我们推断其突变可能通过影响病毒复制进而影响疾病严重程度[49]。Nagy等人[32]的一项研究发现NSP6_L37F、NSP4_F308 Y与轻症新冠病毒感染相关,NSP12_P323L、NSP3_T1198K、NSP3_S1197R、NSP7_L71F、NSP12_A97V与重症新冠病毒感染相关。本研究对这些突变进行了分析,得到了与该文献一致的结果(结果未呈现)。NSP3_T1198K、NSP3_S1197R、NSP12_A97V变异在本研究中不足100例,因而未纳入分析。
本研究的数据来自于GISAID数据库,数据库信息仅包含有关患者预后的一般信息且存在部分缺失数据,因为只有小部分具有患者疾病情况,我们的发现可能包含抽样偏差。数据库中的患者疾病严重程度的判定很大程度上取决于患者所在国家,不同国家对于新冠病毒感染的严重程度判定不完全一致。另外,不同国家的医疗资源、卫生经济条件及个体免疫力差异都可能影响新冠病毒感染的严重程度,本文对一些潜在的混杂因素,如合并症、免疫力状况、针对新冠病毒感染的治疗等没有纳入分析。我们只分析了突变频率前15位的非结构蛋白氨基酸变异,在我们的分析中,可能存在一些潜在影响新冠病毒感染严重程度的非结构蛋白氨基酸变异未被纳入分析。
总的来说,男性新冠病毒感染重症风险高于女性,随着年龄增加,新冠病毒感染重症的风险增加。关注的发病时间、大洲与新冠病毒感染严重程度显著相关。本研究确定了SARS-CoV-2基因组中几种可能与新冠病毒感染严重程度相关的氨基酸变异,NSP4_T492I、NSP12_G671S、NSP6_T77A、NSP3_P1228L与新冠病毒感染重症呈负相关,NSP12_P323L、NSP13_P77L、NSP14_A394V变异增加新冠病毒感染重症风险。本研究初步发现了一些与新冠肺炎疾病严重程度有关的非结构蛋白氨基酸变异,后续将通过构建含有这些突变位点的质粒,研究其在天然免疫逃逸中的作用,探讨这些变异与机体适应性和疾病严重程度的关系。
