| 1 | Paradoxical relationship between proton pump inhibitors and COVID-19: A systematic review and meta-analysis显示文摘BACKGROUND The proton pump inhibitors(PPIs),used to reduce gastric acid secretion,represent one of the most widely used pharmaceutical classes in the world.Their consumption as a risk factor for the evolution of severe forms of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection has been investigated as well as the mortality of these patients.These risks also appear to be linked to the duration and the dosage.On the other hand,several studies have emerged with regard to the protective or therapeutic effects of these drugs.More and more evidence underlines the immunomodulatory and anti-fibrotic role of PPIs.In addition,their ability to alkalize the contents of endosomes and lysosomes serves as an obstacle to the entry of the virus into the host cells.AIM To identify studies on the relationship between the intake of PPIs and coronavirus disease 2019(COVID-19)in patients affected by SARS-CoV-2 infection,with the main objective of evaluating the outcomes related to severity and mortality.METHODS A literature review was performed in November 2020.The MEDLINE/PubMed,Cochrane Library,EMBASE and Google Scholar databases were searched for all relevant articles published in English on this topic.The search terms were identified by means of controlled vocabularies,such as the National Library of Medicine’s MESH(Medical Subject Headings)and keywords.The MESH terms and keywords used were as follows:“COVID-19”,“proton pump inhibitors”,“PPIs”,“SARS-CoV-2”,“outcomes”,“severity”and“mortality”.The inclusion criteria regarding the studies considered in our analysis were:meta-analysis,casecontrol,hospital-based case-control,population-based case-control,retrospective studies,online survey,as well as cohort-studies,while articles not published as full reports,such as conference abstracts,case reports and editorials were excluded.We tried to summarize and pool all the data if available.RESULTS A total of 9 studies were found that described the use of PPIs,of which only 5 clearly reported the severity and mortality data in SARS-CoV-2 patients.Our pooled incidence analysis of severe events did not differ between patients with and without PPIs(odds ratio 1.65,95%confidence interval:0.62-4.35)(P=0.314),or for mortality(odds ratio 1.77,95%confidence interval:0.62-5.03)(P=0.286).CONCLUSION Detailed and larger case studies are needed to accurately understand the role of PPIs in this viral infection. | Maddalena Zippi Sirio Fiorino Roberta Budriesi Matteo Micucci Ivan Corazza Roberta Pica Dario de Biase Claudio Giuseppe Gallo Wandong Hong | 2021 | World Journal of Clinical Cases2021，9，12： | 2 |
| 2 | Epidemiological features and dynamic changes in blood biochemical indices for COVID-19 patients in Hebi显示文摘BACKGROUND Millions of people have died of coronavirus disease 2019(COVID-19)due to severe acute respiratory syndrome coronavirus 2(SARS-Co V-2)infection,and retrospective studies of the disease in local regions are necessary.AIM To characterize the epidemiological features and dynamic changes in blood biochemical indices for SARS-Co V-2-infected patients in Hebi,a representative city with a large floating population in North China.METHODS From January 25 to February 10,2020,the clinical data of patients who tested positive for SARS-Co V-2 by quantitative real-time polymerase chain reaction in Hebi city(China)were evaluated at admission,and laboratory data for hematologic parameters,inflammatory indices,coagulation function indices,liver function indices,blood lipid indices,renal function indices,myocardial enzyme activities and five blood biochemical markers of immunity were evaluated at admission,upon hospitalization and before discharge.RESULTS Sixteen confirmed COVID-19 patients developed pneumonia but were cured after adequate treatment.Fever and fatigue were the common symptoms.The most common laboratory abnormalities of patients at admission were leukopenia,eosinopenia,decreased percentage of eosinophils,elevated high sensitivity C-reactive protein and fibrinogen levels,hypoalbuminemia,mildly increased aspartate transferase activity and levels of bilirubin,and increased levels ofβ2-microglobulin.Importantly,aggravated liver dysfunction was detected in most patients,which may be partially attributed to virus infection as well as medicinal treatment.CONCLUSION This study provides several potential diagnostic markers and dynamic biochemical indices of disease progression to better prevent,diagnose and treat COVID-19 infection. | Xiao-Bo Nie Bao-Sheng Shi Lin Zhang Wei-Li Niu Ting Xue Lan-Qing Li Xiao-Yun Wei Yan-Dong Wang Wei-Dong Chen Rui-Fang Hou | 2022 | World Journal of Clinical Cases2022，10，8： | 1 |
| 3 | Clinical characteristics of patients with COVID-19 presenting with gastrointestinal symptoms as initial symptoms: Retrospective case series显示文摘BACKGROUND A large number of pneumonia cases due to coronavirus disease 2019(COVID-19)have been first reported in China.Meanwhile,the virus is sweeping all around the world and has infected millions of people.Fever and pulmonary symptoms have been noticed as major and early signs of infection,whereas gastrointestinal symptoms were also observed in a significant portion of patients.The clinical investigation of disease onset was underestimated,especially due to the neglection of cases presenting with gastrointestinal symptoms.AIM To characterize the clinical features of coronavirus-infected patients with gastrointestinal symptoms as initial symptoms.METHODS This is a retrospective,single-center case series of the general consecutive hospitalized patients with confirmed COVID-19 at Wuhan Union Hospital from February 2,2020 to February 13,2020.According to their initial symptoms,these patients were classified into two groups.Patients in group one presented with pulmonary symptoms(PS)as initial symptoms,and group two presented with gastrointestinal symptoms(GS).Epidemiological,demographic,clinical,laboratory,and treatment data were collected for analysis.RESULTS Among the 50 patients recruited,no patient has been admitted to intensive care units,and no patient died during the study.The duration of hospitalization was longer in the GS group than in the PS group(12.13±2.44 vs 10.00±2.13,P<0.01).All of the 50 patients exhibited decreased lymphocytes.However,lymphocytes in the GS group were significantly lower compared to those in the PS group(0.94±0.06 vs 1.04±0.15,P<0.01).Procalcitonin and hs-CRP were both significantly higher in the GS group than in the PS group.Accordingly,the duration of viral shedding was significantly longer in the GS group compared to the PS group(10.22±1.93 vs 8.15±1.87,P<0.01).CONCLUSION COVID-19 patients presenting with gastrointestinal symptoms as initial symptoms need more days of viral shedding and hospitalization than the patients presenting with pulmonary symptoms. | Yun Yang Yuan-Chao Li Si-Cong Wang Qing-Qing Dai Xue-Song Jiang Shu Zuo Liu Jia Jun-Bo Zheng Hong-Liang WangDepartment of Critical Care Medicine the Second Affiliated Hospital of | 2020 | World Journal of Clinical Cases2020，8，14： | 0 |
| 4 | Severe hypertransaminasemia during mild SARS-CoV-2 infection:A pediatric case report and literature review显示文摘Introduction:Liver injury during SARS-CoV-2 infection has a multifactorial pathogenesis and it is frequent in pediatric cases.Case presentation:We report a case with severe hypertransaminasemia associated with mild SARS-CoV-2 infection.Conclusion:This highlights the potential need of hepatic function evaluation during acute illness and follow-up even in non-critically ill children with COVID-19. | Alessandra Palpacelli Gaia Martelli Bianca Lattanzi Alessandro Volpini Salvatore Cazzato | 2021 | Pediatric Investigation2021，5，4： | 0 |
