Venous thromboembolism (VTE) is a life-threatening complication observed among patients with sickle cell disease (SCD) and also among those with severe COVID-19 infection. Although prior studies show that patients with SCD are at risk of severe COVID-19 illness, it remains unclear if COVID-19 infection further increases VTE risk for this population. We hypothesized that patients with SCD hospitalized for COVID-19 would have higher VTE rates than those hospitalized for other causes. Using electronic health record data from a multisite research network, TriNetX, we identified 2 groups of patients with SCD hospitalized during 2020: (1) with COVID-19 and (2) without COVID-19. We compared VTE rates using risk ratios estimated based on adjusted Poisson regression model with log link and robust error variances. Of the 281 SCD patients hospitalized with COVID-19 and 4873 SCD patients hospitalized without COVID-19 , 35 (12.46%) and 418 (8.58%) had incident VTE within 6 months of the index hospitalization respectively. After adjusting for differences in baseline characteristics, no significant differences in VTE rates within 6 months were found between the 2 groups (adjusted relative risk, 1.06 [95% confidence interval, 0.79-1.41]). These data suggest that hospitalization with COVID-19 does not further increase VTE risk in patients with SCD.
静脉血栓栓塞症 (VTE) 是镰状细胞病 (SCD) 患者和严重 COVID-19 感染患者中观察到的危及生命的并发症。尽管先前的研究表明 SCD 患者有发生严重 COVID-19 疾病的风险,但尚不清楚 COVID-19 感染是否会进一步增加该人群的 VTE 风险。我们假设因 COVID-19 住院的 SCD 患者的 VTE 发生率高于因其他原因住院的患者。我们使用来自多站点研究网络 TriNetX 的电子健康记录数据,确定了 2020 年因 COVID-19 和非 COVID-19 住院的 SCD 患者 2 组:(1)COVID-19 组和(2)非 COVID-19 组。我们使用基于调整后的泊松回归模型(对数链接和稳健误差方差)估计的风险比比较 VTE 发生率。在因 COVID-19 住院的 281 例 SCD 患者和因非 COVID-19 住院的 4873 例 SCD 患者中,分别有 35 例(12.46%)和 418 例(8.58%)在指数住院后 6 个月内发生了 VTE。在调整了基线特征差异后,2 组之间 6 个月内的 VTE 发生率没有显著差异(调整后的相对风险,1.06 [95%置信区间,0.79-1.41])。这些数据表明 COVID-19 住院不会进一步增加 SCD 患者的 VTE 风险。
