Coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 has been associated with a high risk of adverse outcomes in solid organ transplant (SOT) recipients in the pre-vaccination era. In this retrospective cohort study, we examined the incidence and severity of COVID-19 in kidney and liver transplant recipients in Denmark in the post-vaccination era, from December 27, 2020, to December 27, 2021. We included 1428 SOT recipients with 143 cases of first-positive SARS-CoV-2 PCR test. The cumulative incidence of first-positive SARS-CoV-2 PCR test 1 year after initiation of vaccination was 10.4% (95% CI: 8.8–12.0), and the incidence was higher in kidney than in liver transplant recipients (11.6% [95% CI: 9.4–13.8] vs. 7.4% [95% CI: 5.1–9.8], p = .009). After the first-positive SARS-CoV-2 PCR test, the hospitalization rate was 31.5% (95% CI: 23.9–39.1), and 30-day all-cause mortality was 3.7% (95% CI: 0.5–6.8). Hospitalization was lower in vaccinated than in unvaccinated SOT recipients (26.4% [95% CI: 18.1–34.6] vs. 48.5% [95% CI: 31.4–65.5], p = .011), as was mortality (1.8% [95% CI: 0.0–4.3] vs. 9.1% [95% CI: 0.0–18.9], p = .047). In conclusion, SOT recipients remain at high risk of adverse outcomes after SARS-CoV-2 infections, with a lower risk observed in vaccinated than in unvaccinated SOT recipients.

疫苗接种后时代肝肾移植受者 SARS-CoV-2 感染的发生率和严重程度:来自丹麦的真实数据

由 SARS-CoV-2 引起的 2019 年冠状病毒病 (COVID-19) 与疫苗接种前时代实体器官移植 (SOT) 接受者发生不良后果的高风险有关。在这项回顾性队列研究中,我们检查了疫苗接种后时代(2020 年 12 月 27 日至 2021 年 12 月 27 日)丹麦肾脏和肝脏移植受者中 COVID-19 的发病率和严重程度。我们纳入了 1428 名 SOT 受者,其中 143 名SARS-CoV-2 PCR 检测首次呈阳性的病例。开始接种疫苗后 1 年首次 SARS-CoV-2 PCR 检测阳性的累积发生率为 10.4%(95% CI:8.8-12.0),肾脏的发生率高于肝移植受者(11.6% [95 % CI:9.4–13.8] 对比 7.4% [95% CI:5.1–9.8],p =.009)。首次 SARS-CoV-2 PCR 检测呈阳性后,住院率为 31.5%(95% CI:23.9-39.1),30 天全因死亡率为 3.7%(95% CI:0.5-6.8)。接种疫苗的 SOT 接受者的住院率低于未接种疫苗的 SOT 接受者(26.4% [95% CI:18.1–34.6] 对比 48.5% [95% CI:31.4–65.5],p  = .011),死亡率(1.8% [95] % CI:0.0–4.3] 对比 9.1% [95% CI:0.0–18.9],p  = .047)。总之,SOT 接受者在 SARS-CoV-2 感染后仍处于不良后果的高风险中,与未接种疫苗的 SOT 接受者相比,接种疫苗的风险较低。
