| 1 | Role of relevant immune-modulators and cytokines in hepatocellular carcinoma and premalignant hepatic lesions显示文摘AIM To assess the levels of different immune modulators in patients with hepatocellular carcinoma(HCC),in relation to other hepatic diseases.METHODS Eighty-eight patients were included in the current study and represented patients with HCC(20),liver cirrhosis(28) and chronic hepatitis(CH;25),and normal controls(NC;15).Peripheral blood was isolated for immunophenotyping of active myeloid dendritic cells(m DCs;CD1 c and CD40),mature inactive myeloid cells(CD1 c and HLA),active plasmacytoid cells(p DCs;CD303 and CD40),mature inactive p DCs(CD30 and HLA),active natural killer(NK) cells(CD56 and CD161),active NK cells(CD56 and CD314) and inactive NK cells(CD56 and CD158) was done by flow cytometry.Serum levels of interleukin(IL)-2,IL-10,IL-12,IL-1β,interferon(IFN)-α,IFN-γ and tumor necrosis factor(TNF)-αR2 were assessed by ELISA.RESULTS Active m DCs(CD1 C+/CD40+) and inactive m DCs(CD1 c+/HLA+) were significantly decreased in HCC patients in relation to NC(P < 0.001).CD40+ expression on active p DCs was decreased in HCC patients(P < 0.001),and its level was not significantly changed among other groups.Inactive p DCs(CD303+/HLA+),inactive NKs(CD56+/CD158+) and active NKs(CD56+/CD161+) were not statistically changed among the four groups studied;however,the latter was increased in CH(P < 0.05).NKG2 D was statistically decreased in HCC,CH and cirrhosis(P < 0.001),and it was not expressed in 63%(12/20) of HCC patients.There was significant decrease of IL-2,IFN-α and IFN-γ(P < 0.001),and a significant increase in IL-10,IL-1β,and TNF-αR2(P <0.01,P < 0.001 and P < 0.001;respectively) in HCC patients.There was inverted correlation between IL-12 and IL-1β in HCC(r =-0.565,P < 0.01),with a strong correlation between p DCs(CD303+/CD40+) and NKs(CD56+/CD161+;r = 0.512,P < 0.05) as well as inactive m DCs(CD1 c+/HLA+) and inactive NK cells(CD56+/CD158+;r = 0.945,P < 0.001).CONCLUSION NKG2 D,CD40,IL-2 and IL-10 are important modulators in the development and progression of HCC. | Abdel-Rahman N Zekri Somaya El Deeb Abeer A Bahnassy Abeer M Badr Mona S Abdellateif Gamal Esmat Hosny Salama Marwa Mohanad Ahmed Esam El-dien Shimaa Rabah Assmaa Abd Elkader | 2018 | World Journal of Gastroenterology2018，24，11： | 6 |
| 2 | Survival and outcomes for co-infection of chronic hepatitis C with and without cirrhosis and COVID-19: A multicenter retrospective study显示文摘BACKGROUND Chronic liver disease,particularly cirrhosis,is associated with worse outcomes in patients infected with coronavirus disease 2019(COVID-19).AIM To assess outcomes of COVID-19 infection among patients with pre-existing hepatitis C with or without liver cirrhosis.METHODS This multicenter,retrospective cohort study included all cases of confirmed coinfection of severe acute respiratory syndrome coronavirus 2 and chronic hepatitis C with or without liver cirrhosis who were admitted to six hospitals(Al-Sahel Hospital,Al-Matareya Hospital,Al-Ahrar Hospital,Ahmed Maher Teaching Hospital,Al-Gomhoreya Hospital,and the National Hepatology and Tropical Medicine Research Institute)affiliated with the General Organization for Teaching Hospitals and Institutes in Egypt.Patients were recruited from May 1,2020,to July 31,2020.Demographic,laboratory,imaging features,and outcomes were collected.Multivariate regression analysis was performed to detect factors affecting mortality.RESULTS This retrospective cohort study included 125 patients with chronic hepatitis C and COVID-19 co-infection,of which 64(51.20%)had liver cirrhosis and 40(32.00%)died.Fever,cough,dyspnea,and fatigue were the most frequent symptoms in patients with liver cirrhosis.Cough,sore throat,fatigue,myalgia,and diarrhea were significantly more common in patients with liver cirrhosis than in noncirrhotic patients.There was no difference between patients with and without cirrhosis regarding comorbidities.Fifteen patients(23.40%)with liver cirrhosis presented with hepatic encephalopathy.Patients with liver cirrhosis were more likely than non-cirrhotic patients to have combined ground-glass opacities and consolidations in CT chest scans:28(43.75%)vs 4(6.55%),respectively(P value<0.001).These patients also were more likely to have severe COVID-19 infection,compared to patients without liver cirrhosis:29(45.31%)vs 11(18.04%),respectively(P value<0.003).Mortality was higher in patients with liver cirrhosis,compared to those with no cirrhosis:33(51.56%)vs 9(14.75%),respectively(P value<0.001).All patients in Child-Pugh class A recovered and were discharged.Cirrhotic mortality occurred among decompensated patients only.A multivariate regression analysis revealed the following independent factors affecting mortality:Male gender(OR 7.17,95%CI:2.19–23.51;P value=0.001),diabetes mellitus(OR 4.03,95%CI:1.49–10.91;P value=0.006),and liver cirrhosis(OR 1.103,95%CI:1.037–1.282;P value<0.0001).We found no differences in liver function,COVID-19 disease severity,or outcomes between patients who previously received direct-acting antiviral therapy(and achieved sustained virological response)and patients who did not receive this therapy.CONCLUSION Patients with liver cirrhosis are susceptible to higher severity and mortality if infected with COVID-19.Male gender,diabetes mellitus,and liver cirrhosis are independent factors associated with increased mortality risk. | Shimaa Afify Basem Eysa Fatma Abdel Hamid Omnia M Abo-Elazm Mohamed A Edris Rabab Maher Ahmed Abdelhalim Muhammad Mostafa Abdel Ghaffar Dalia A Omran Hend Ibrahim Shousha | 2021 | World Journal of Gastroenterology2021，27，42： | 2 |

| 5 | Hepatic and gastrointestinal disturbances in Egyptian patients infected with coronavirus disease 2019: A multicentre cohort study显示文摘BACKGROUND Various liver and gastrointestinal involvements occur in patients with coronavirus disease 2019(COVID-19)at variable prevalence.Most studies report mild liver function disturbances correlated with COVID-19 severity,though liver failure is unusual.AIM To study liver and gastrointestinal dysfunctions in Egyptian patients with COVID-19 and their relation to disease outcomes METHODS This multicentre cohort study was conducted on 547 Egyptian patients from April 15,2020 to July 29,2020.Consecutive polymerase chain reaction-confirmed COVID-19 cases were included from four quarantine hospitals affiliated to the Egyptian ministry of health.Demographic information,laboratory characteristics,treatments,fibrosis-4(FIB-4)index,COVID-19 severity,and outcomes were recorded and compared according to the degree of liver enzyme elevation and the presence of gastrointestinal symptoms.Follow-ups were conducted until discharge or death.Regression analyses were performed to determine the independent factors affecting mortality.RESULTS This study included 547 patients,of whom 53(9.68%)died during hospitalization and 1 was discharged upon his request.Patients’mean age was 45.04±17.61 years,and 21.98%had severe or critical COVID-19.Alanine aminotransferase(ALT)and aspartate aminotransferase(AST)were available for 430 and 428 patients,respectively.In total,26%and 32%of patients had elevated ALT and AST,respectively.Significant liver injury with ALT or AST elevation exceeding 3-fold was recorded in 21(4.91%)and 16(3.73%)patients,respectively.Male gender,smoking,hypertension,chronic hepatitis C,and lung involvement were associated with elevated AST or ALT.AST was elevated in 50%of patients over 60-years-old.FIB-4 was significantly higher in patients admitted to the intensive care unit(ICU),those with more severe COVID-19,and non-survivors.The independent variables affecting outcome were supplementary vitamin C intake(1 g daily capsules)[odds ratio(OR):0.05,95%confidence interval(CI):0.008–0.337];lung consolidation(OR:4.540,95%CI:1.155–17.840);ICU admission(OR:25.032,95%CI:7.110–88.128);and FIB-4 score>3.25(OR:10.393,95%CI:2.459-43.925).Among 60(13.98%)patients with gastrointestinal symptoms,52(86.67%)had diarrhoea.Patients with gastrointestinal symptoms were predominantly females with higher body mass index,and 50(83.40%)patients had non-severe COVID-19.CONCLUSION Few Egyptian patients with COVID-19 developed a significant liver injury.The independent variables affecting mortality were supplementary vitamin C intake,lung consolidation,ICU admission,and FIB-4 score. | Hend Ibrahim Shousha Shimaa Afify Rabab Maher Noha Asem Eman Fouad Ehab F Mostafa Mohammed A Medhat Amr Abdalazeem Hazem Elmorsy Miriam M Aziz Rateba S Mohammed Mohamed Ibrahem Hassan Elgarem Dalia Omran Mohamed Hassany Bassem Elsayed Ahmed Y Abdelaziz Mohamed El Kassas | 2021 | World Journal of Gastroenterology2021，27，40： | 1 |
| 6 | Barriers for resuming endoscopy service in the context of COVID-19 pandemic:A multicenter survey from Egypt显示文摘BACKGROUND The current coronavirus disease 2019(COVID-19)pandemic has affected routine endoscopy service across the gastroenterology community.This led to the suspension of service provision for elective cases.AIM To assess the potential barriers for resuming the endoscopy service in Egypt.METHODS A national online survey,four domains,was disseminated over a period of 4 wk in August 2020.The primary outcome of the survey was to determine the impact of the COVID-19 pandemic on the endoscopy service and barriers to the full resumption of a disabled center(s).RESULTS A hundred and thirteen Egyptian endoscopy centers participated in the survey.The waiting list was increased by≥50% in 44.9% of areas with clusters of COVID-19 cases(n=49)and in 35.5% of areas with sporadic cases(n=62).Thirty nine(34.8%)centers suffered from staff shortage,which was considered a barrier against service resumption by 86.4% of centers in per-protocol analysis.In multivariate analysis,the burden of cases in the unit locality,staff shortage/recovery and the availability of separate designated rooms for COVID-19 cases could markedly affect the resumption of endoscopy practice(P=0.029,<0.001 and 0.02,respectively)and Odd’s ratio(0.15,1.8 and 0.16,respectively).CONCLUSION The COVID-19 pandemic has led to restrictions in endoscopic volumes.The staff shortage/recovery and the availability of COVID-19 designed rooms are the most important barriers against recovery.Increasing working hours and dividing endoscopy staff into teams may help to overcome the current situation. | Omar Elshaarawy Sameh Aldesoky Lashen Nahed A Makhlouf Doaa Abdeltawab Mariam Salah Zaghloul Rasha M Ahmed Hayam Fathy Shimaa Afifi Muhammad Abdel-Gawad Eman Abdelsameea Sherief Abd-Elsalam Salem Youssef Mohamed Mohammed Tag-Adeen Mina Tharwat Ahmed Alzamzamy Ahmed Nasr Bekhit Alshaimaa M Eid Abeer Awad Mohamed-Naguib Wifi Mohammad Aamr Waleed A Abd El Dayem Mohamed Alboraie | 2020 | World Journal of Gastroenterology2020，26，43： | 0 |
