S evere acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus that causes coronavirus disease 2019 in human beings, has caused a serious public health issue. 1 Attention to pancreatic injury is lacking, which may impact patients' prognosis. In this study, we explored the expression and distribution of angiotensin-converting enzyme 2 (ACE2), the receptor of SARS-CoV-2, in the pancreas. Combined with clinical data, we showed that pancreatic injury can occur in some COVID-19 patients.
MethodsA public database was used to explore the expression and distribution of ACE2 in normal pancreases. We also retrospectively analyzed patients diagnosed with COVID-19 from January 1, 2020, to February 15, 2020, in Wuhan Tongji Hospital and Wuhan Jin Yin-tan Hospital. We collected hospital admission data, laboratory tests, and imaging tests from clinical electronic medical records. Severe COVID-19 was defined when patients had 1 of the following criteria: (1) shortness of breath and respiratory frequency !30/min; (2) finger pulse oximeter oxygen saturation at rest of 93% or less; or (3) oxygenation index of 300 mm Hg or less. More details about clinical data and public data set analysis are described in the Supplementary Methods.
Background and Aims
The evolution and clinical significance of abnormal liver chemistries and the impact of hepatitis B infection on outcome in patients with COVID-19 is not well characterized. This study aimed to explore these issues.
Methods
This large retrospective cohort study included 2073 patients with COVID-19 having definite outcomes in Wuhan, China. Longitudinal liver function tests were conducted and determined their associated factors and death risk by multivariate regression analyses. A prognostic nomogram was formulated to predict the survival of patients with COVID-19. The characteristics of liver abnormalities and outcomes of patients with COVID-19 with and without hepatitis B were compared after 1:3 propensity score matching.
Results
Of the 2073 patients, 1282 (61.8%) had abnormal liver chemistries during hospitalization, and 297 (14.3%) had a liver injury. The mean levels of AST and D-Bil increased early after symptom onset in deceased patients and showed disparity compared with that in discharged patients throughout the clinical course of the disease. Abnormal admission AST (adjusted hazard ratio [HR]: 1.39, 95%CI: 1.04-1.86,
P
=0.027) and D-Bil (adjusted HR: 1.66, 95%CI: 1.22-2.26,
P
=0.001) levels were independent risk factors for mortality due to COVID-19. A nomogram was established based on the results of multivariate analysis and showed sufficient discriminatory power and good consistency between the prediction and the observation. HBV infection in patients did not increase the risk of COVID-19-associated poor outcomes.
Conclusions
Abnormal AST and D-Bil levels at admission were independent predictors of COVID-19 mortality. Therefore, monitoring liver chemistries, especially AST and D-Bil levels, in hospitalized patients with COVID-19, is necessary.
Liver resection with thrombectomy yielded better outcomes in the HCC patients with PVTT confined to the first or second branch of the main portal vein compared with PVTT extending into the main portal vein.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
