Since December 2019, coronavirus disease 2019 (COVID-19) outbreak occurred and has rapidly spread worldwide. However, little information is available about the AKI in COVID-19. We aimed to evaluate the incidence, risk factors, and prognosis of AKI in adult patients with COVID-19.
DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: This was a retrospective cohort study of 1392 patients with COVID-19 admitted to a tertiary teaching hospital. Clinical characteristics and laboratory data were extracted from electronic hospitalization and laboratory databases. AKI was defined and staged according to the 2012 Kidney Disease: Improving Global Outcomes criteria. Risk factors for AKI and the association of AKI with in-hospital mortality were assessed.
A total of 7% (99 of 1392) of patients developed AKI during hospitalization, 40% (40 of 99) of which occurred within 1 week of admission. Factors associated with a higher risk of AKI include severe disease (odds ratio [OR], 2.25; 95% confidence interval [CI], 1.37 to 3.67), higher baseline serum creatinine (OR, 2.19; 95% CI, 1.17 to 4.11), lymphopenia (OR, 1.99; 95% CI, 1.12 to 3.53), and elevated D-dimer level (OR, 2.68; 95% CI, 1.07 to 6.70). The in-hospital mortality in patients with AKI stage 1, stage 2, and stage 3 was 62%, 77%, and 80%, respectively. AKI was associated with in-hospital mortality even after adjustment for confounders (OR, 5.12; 95% CI, 2.70 to 9.72).
AKI is uncommon but carries high in-hospital mortality in patients with COVID-19.
自 2019 年 12 月以来，新型冠状病毒病 2019（COVID-19）爆发并迅速在全球范围内蔓延。然而，关于 COVID-19 导致的急性肾损伤（AKI）的信息较少。本研究旨在评估成人 COVID-19 患者 AKI 的发生率、危险因素和预后。
设计、地点、参与者和测量方法：这是一项对 1392 例在一家三级教学医院住院的 COVID-19 患者进行的回顾性队列研究。从电子住院和实验室数据库中提取临床特征和实验室数据。根据 2012 年肾脏病：改善全球结局（KDIGO）标准定义和分期 AKI。评估 AKI 的危险因素以及 AKI 与住院死亡率的关系。
共有 7%（99/1392）的患者在住院期间发生 AKI，其中 40%（40/99）发生在入院后 1 周内。与 AKI 风险较高相关的因素包括严重疾病（比值比[OR]，2.25；95%置信区间[CI]，1.37 至 3.67）、基线血清肌酐升高（OR，2.19；95%CI，1.17 至 4.11）、淋巴细胞减少症（OR，1.99；95%CI，1.12 至 3.53）和升高的 D-二聚体水平（OR，2.68；95%CI，1.07 至 6.70）。AKI 1 期、2 期和 3 期患者的住院死亡率分别为 62%、77%和 80%。即使在调整混杂因素后，AKI 与住院死亡率相关（OR，5.12；95%CI，2.70 至 9.72）。
AKI 在 COVID-19 患者中并不常见，但住院死亡率高。
