In early 2019, a new coronavirus called SARS-CoV-2 emerged and changed the course of civilization. Our study aims to analyze the association between acute liver failure (ALF) and mortality in patients infected with COVID-19. A retrospective analysis of 864 COVID-19-infected patients admitted to Nassau University Medical Center in New York was performed.
ALF is identified by acute liver injury (elevations in liver enzymes), hepatic encephalopathy and an international normalised ratio greater than or equal to 1.5. These parameters were analysed via daily blood work and clinical assessment. Multivariate logistic regression model predicting mortality and controlling for confounders such as age, coronary artery disease, intubation, hypertension, diabetes mellitus and acute kidney injury were used to determine the association of ALF with mortality.
A total of 624 patients, out of the initial 864, met the inclusion criteria-having acute hepatitis and COVID-19 infection. Of those 624, 43 (6.9%) patients developed ALF during the course of their hospitalisation and their mortality rate was 74.4%. The majority of patients with ALF were male (60.6%). The logistic model predicting death and controlling for confounders shows COVID-19 patients with ALF had a nearly four-fold higher odds of death in comparison to those without ALF (p=0.0063).
Findings from this study suggest that there is a significant association between mortality and the presence of ALF in patients infected with COVID-19. Further investigation into patients with COVID-19 and ALF can lead to enhanced treatment regimens and risk stratification tools, which can ultimately improve mortality rates during these arduous times.
2019 年初,一种新型冠状病毒 SARS-CoV-2 出现,改变了文明的进程。本研究旨在分析 COVID-19 感染患者中急性肝衰竭(ALF)与死亡率之间的关系。对纽约拿骚大学医学中心收治的 864 例 COVID-19 感染患者进行回顾性分析。
ALF 通过急性肝损伤(肝酶升高)、肝性脑病和国际标准化比值大于或等于 1.5 来确定。这些参数通过每日血液检查和临床评估进行分析。使用多变量逻辑回归模型预测死亡率,并控制混杂因素(如年龄、冠状动脉疾病、插管、高血压、糖尿病和急性肾损伤),以确定 ALF 与死亡率的关系。
在最初的 864 例患者中,共有 624 例符合纳入标准,即患有急性肝炎和 COVID-19 感染。在这 624 例患者中,有 43 例(6.9%)患者在住院期间出现 ALF,其死亡率为 74.4%。大多数 ALF 患者为男性(60.6%)。预测死亡的逻辑模型并控制混杂因素表明,与没有 ALF 的 COVID-19 患者相比,患有 ALF 的 COVID-19 患者死亡的可能性几乎高出四倍(p=0.0063)。
本研究结果表明,COVID-19 感染患者的死亡率与 ALF 的存在之间存在显著关联。对 COVID-19 合并 ALF 的患者进行进一步研究,可以开发出更好的治疗方案和风险分层工具,从而最终在这些艰难时期提高死亡率。
