BACKGROUND: After the reports of severe adverse reactions to the AstraZeneca ChAdOx1-S-nCoV-19 vaccine, patients who had received one dose of ChAdOx1-S-nCoV-19 vaccine were recommended a second dose of Pfizer's BNT162b2 vaccine. In hemodialysis patients, we compared the humoral immunogenicity and tolerability of homologous vaccination with ChAdOx1-nCoV-19/ChAdOx1-nCoV-19 (ChAd/ChAd) and BNT162b2/BNT162b2 (BNT/BNT) with heterologous vaccination of first dose of ChAdOx1-nCoV-19 and a second dose with BNT162b2 (ChAd/BNT). METHODS: In a multicenter prospective observational study, SARS-CoV-2 spike-IgG antibody levels, Nucleocapsid-protein-IgG-antibodies, and vaccine tolerability were assessed 6 weeks after second SARS-CoV-2 vaccination in 137 hemodialysis patients and 24 immunocompetent medical personnel. RESULTS: In COVID-19-naïve hemodialysis patients, significantly higher median SARS-CoV-2-spike IgG levels were found after ChAd/BNT (N = 16) compared to BNT/BNT (N = 100) or ChAd/ChAd (N = 10) (1744 [25th-75th percentile 276-2840] BAU/mL versus 361 [25th-75th percentile 120-936] BAU/mL; p = 0.009; 1744 [25th-75th percentile 276-2840] BAU/mL versus 100 [25th-75th percentile 41-346] BAU/mL; p = 0.017, respectively). Vaccinated, COVID-19-naïve medical personnel had median SARS-CoV-2 spike-IgG levels of 650 (25th-75th percentile 217-1402) BAU/mL and vaccinated hemodialysis patients with prior COVID-19 7047 (25th-75th percentile 685-10,794) BAU/mL (N = 11). In multivariable regression analysis, heterologous vaccination (ChAd/BNT) of COVID-19-naïve hemodialysis patients was independently associated with SARS-CoV-2 spike-IgG levels. The first dose of ChAd and the second dose of BNT after the first vaccination with ChAd (heterologous vaccination, ChAd/BNT) were associated with more frequent but manageable side effects compared with homologous BNT. CONCLUSIONS: Within the limitations of this study, heterologous vaccination with ChAd/BNT appears to induce stronger humoral immunity and more frequent but manageable side effects than homologous vaccination with BNT/BNT or with ChAd/ChAd in COVID-19-naïve hemodialysis patients.
背景:在阿斯利康 ChAdOx1-S-nCoV-19 疫苗出现严重不良反应报告后,建议已接种一剂 ChAdOx1-S-nCoV-19 疫苗的患者接种第二剂辉瑞公司的 BNT162b2 疫苗。在血液透析患者中,我们比较了同源接种 ChAdOx1-nCoV-19/ChAdOx1-nCoV-19(ChAd/ChAd)和 BNT162b2/BNT162b2(BNT/BNT)与异源接种第一剂 ChAdOx1-nCoV-19 和第二剂 BNT162b2(ChAd/BNT)的免疫原性和耐受性。
方法:在一项多中心前瞻性观察性研究中,在 137 名血液透析患者和 24 名免疫功能正常的医务人员中,在第二次 SARS-CoV-2 接种后 6 周评估了 SARS-CoV-2 刺突 IgG 抗体水平、核衣壳蛋白 IgG 抗体和疫苗耐受性。
结果:在 COVID-19 初治的血液透析患者中,ChAd/BNT(N=16)组的 SARS-CoV-2 刺突 IgG 水平明显高于 BNT/BNT(N=100)或 ChAd/ChAd(N=10)组(1744[25th-75th 百分位数 276-2840]BAU/mL 比 361[25th-75th 百分位数 120-936]BAU/mL;p=0.009;1744[25th-75th 百分位数 276-2840]BAU/mL 比 100[25th-75th 百分位数 41-346]BAU/mL;p=0.017)。接种疫苗、COVID-19 初治的医务人员 SARS-CoV-2 刺突 IgG 水平中位数为 650(25th-75th 百分位数 217-1402)BAU/mL,COVID-19 既往感染的血液透析患者为 7047(25th-75th 百分位数 685-10794)BAU/mL(N=11)。在多变量回归分析中,COVID-19 初治血液透析患者的异源接种(ChAd/BNT)与 SARS-CoV-2 刺突 IgG 水平独立相关。与同源 BNT 相比,ChAd 的第一剂和 BNT 的第二剂(异源接种,ChAd/BNT)后接种 ChAd 后与更频繁但可管理的副作用相关。
结论:在本研究的限制范围内,与同源 BNT/BNT 或 ChAd/ChAd 接种相比,COVID-19 初治血液透析患者的 ChAd/BNT 异源接种似乎诱导更强的体液免疫和更频繁但可管理的副作用。
