1COVID-19-associated gastrointestinal and liver injury:clinical features and potential mechanisms显示文摘Coronavirus disease-2019(COVID-19)is caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).The infection is spreading globally and poses a huge threat to human health.Besides common respiratory symptoms,some patients with COVID-19 experience gastrointestinal symptoms,such as diarrhea,nausea,vomiting,and loss of appetite.SARS-CoV-2 might infect the gastrointestinal tract through its viral receptor angiotensin-converting enzyme 2(ACE2)and there is increasing evidence of a possible fecal–oral transmission route.In addition,there exist multiple abnormalities in liver enzymes.COVID-19-related liver injury may be due to drug-induced liver injury,systemic inflammatory reaction,and hypoxia–ischemia reperfusion injury.The direct toxic attack of SARS-CoV-2 on the liver is still questionable.This review highlights the manifestations and potential mechanisms of gastrointestinal and hepatic injuries in COVID-19 to raise awareness of digestive system injury in COVID-19.Peijie Zhong Jing Xu Dong Yang Yue Shen Lu Wang Yun Feng Chunling Du Yuanlin Song Chaomin Wu Xianglin Hu Yangbai Sun 2020Signal Transduction and Targeted Therapy2020,5,1:1
2Transaminitis is an indicator of mortality in patients with COVID-19:A retrospective cohort study显示文摘BACKGROUND Since its discovery in Wuhan,China in December of 2019,the novel coronavirus has progressed to become one of the worst pandemics seen in the last 100 years.Recently,there has been an increased interest in the hepatic manifestations of coronavirus disease 19(COVID-19).AIM To describe the demographic and clinical characteristics of COVID-19 positive patients and study the association between transaminitis and all-cause mortality.METHODS This is a descriptive retrospective cohort study of 130 consecutive patients with a positive COVID PCR test admitted between March 16,2020 to May 14,2020 at a tertiary care University-based medical center.The Wilcoxon-rank sum test and paired t-test were used for comparing non-parametric and parametric continuous variables respectively and a multivariable logistic regression models to study the association between transaminitis and mortality using SAS version 9.4(SAS Institute,Cary,NC,United States).RESULTS Out of the 130 patients,73(56%)patients were found to have transaminitis and 57(44%)did not.When compared to patients without transaminitis,the transaminitis group was found to have a higher median body mass index(30.2 kg/m2 vs 27.3 kg/m2,P=0.04).In the multivariate analysis those with transaminitis were found to have 3.4 times higher odds of dying as compared to those without transaminitis adjusting for gender,the Age-adjusted Charlson Comorbidity Index and admission to the intensive care unit(P=0.03).CONCLUSION Our study showed that transaminitis on admission was associated with severe clinical outcomes such as admission to the intensive care unit,need for mechanical ventilation,and mortality.Vishnu Charan Suresh Kumar Prateek Suresh Harne Samiran Mukherjee Kashvi Gupta Umair Masood Anuj Vikrant Sharma Jivan Lamichhane Amit Singh Dhamoon Bishnu Sapkota 2020World Journal of Hepatology2020,12,9:0
