2022年上半年,上海、吉林等地遭遇一轮奥密克戎疫情,对本轮疫情中肝移植受者的奥密克戎感染状况和疫苗接种状况进行了一项多中心回顾性队列研究,研究结果2022年10月13日在线发表于国际期刊 Emerg Microbes Infect。
使用电子问卷收集截至2022年6月的人口统计数据、疫苗接种信息、肝移植史和COVID-19感染特征。共纳入1881名参与者(487名接种者和1394名未接种者),来自七个中心。
结果显示:①14名参与者感染了奥密克戎,50%的患者有超过14天的病毒脱落持续时间。②COVID-19疫苗对奥密克戎的保护率为2.59%。③三例突破性感染均发生在完全接种后6个月以上。④总共有96名(19.7%)接种疫苗的患者出现不良事件,包括疲劳、肌痛、肝功能障碍、肿胀和硬结。⑤术前接种组3级不良事件发生率高于术后接种组。
研究者认为,全病毒灭活SARS-CoV-2疫苗对肝移植术后患者是安全的。尽管COVID-19疫苗对肝移植受者奥密克戎的保护率只有2.59%,且极个别接种者出现肝功能障碍的不良事件,但是鉴于接种6个月后灭活疫苗的效力下降,研究者仍然建议,肝移植受者即使完全接种疫苗,也要尽早加强接种。研究者警告,虽然奥密克戎感染在肝移植患者的临床表现是轻微的,但未接种疫苗的患者在感染期间可能有更高的肝功能障碍的风险。

原文摘要(Abstract):
Background & aims: A wave of Omicron infections rapidly emerged in China in 2022, but large-scale data concerning the safety profile of vaccines and Coronavirus disease 2019 (COVID-19) infection features in liver transplant (LT) recipients have not been collected. Therefore, the aim of this study was to assess the protectiveness and safety profile of the inactivated vaccines in LT patients against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant infections.
Methods: A multi-center retrospective study was conducted in a cohort with a history of liver transplantation. Electronic questionnaires were used to collect data on demographics, vaccination information, history of liver transplantation, and characteristics of COVID-19 infection until June 2022. The vaccine information included number of doses, vaccine type, injection time, and adverse events.
Results: A total of 1881 participants (487 vaccinated and 1394 unvaccinated patients) were enrolled from seven centers in China. Fourteen of the participants were infected by Omicron, and 50% patients had over 14 days of viral shedding duration. The protection rate of COVID-19 vaccinations to Omicron was 2.59%. The three breakthrough infections occurred more than 6 months after fully vaccinated. A total of 96 (19.7%) vaccinated patients had adverse events, including fatigue, myalgia, liver dysfunction, swelling, and scleroma. There were more Grade 3 adverse events in the preoperative vaccination group than those in the postoperative vaccination group.
Conclusion: Inactivated whole-virion SARS-CoV-2 vaccines are safe in patients with post-liver transplantation. The efficacy of inactivated vaccines decreases after 6 months of vaccination, it is recommended that liver transplant patients get boosted vaccinations as early as possible even when they are fully vaccinated. Although clinical manifestations of Omicron infections were mild in LT patients, unvaccinated patients might have a higher risk of liver dysfunction during infections.
