| 1 | Aspartate transaminase to platelet ratio index in hepatitis C virus and Schistosomiasis coinfection显示文摘AIM: To assess the diagnostic accuracy,of aminotransferase-to-platelet ratio index(APRI) alone and with antischistosomal antibody(Ab) in patients with hepatitis C virus(HCV) and schistosomiasis coinfection. METHODS: This retrospective study included medical records of three hundred and eighty three Egyptianmen patients who had undergone percutaneous liver biopsy between January 2006 to April 2014 in tertiary care hospital in Qatar for diagnosis or monitoring purpose were selected. Data of patients > 18 years of age were included in the study. The values of HCV RNA titer and antischistosomal antibody titer were also taken into consideration. Patients were excluded from the study if they had any other concomitant chronic liver disease,including; history of previous antiviral or interferon therapy,immunosuppressive,therapy,chronic hepatitis B infection,human immunodeficiency virus co-infection,autoimmune hepatitis,decompensated liver disease,hepatocellular carcinoma,prior liver transplantation,and if no data about the liver biopsy present. RESULTS: Median age of patients was 46 years. About 7.1% had no fibrosis,whereas 30.4%,37.5%,20.4%,and 4.6% had fibrosis of stage Ⅰ,Ⅱ,Ⅲ,and Ⅳ respectively. In bivariate analysis,APRI score,levels of AST,platelet count and age of patient showed statistically significant association with liver fibrosis(P < 0.0001); whereas antischistosomal antibody titer(P = 0.52) and HCV RNA titer(P = 0.79) failed to show a significant association. The respective AUC values for no fibrosis,significant fibrosis,severe fibrosis and cirrhosis of APRI score were 63%,73.2%,81.1% and 88.9% respectively. This showed good sensitivity and specificity of APRI alone for grading of liver fibrosis. But the inclusion of anti-Schistosoma antibody did not improve the prediction of fibrosis stage. CONCLUSION: The study results suggest that noninvasive biochemical markers like APRI are sensitive and specific in diagnosing the degree of fibrosis and cirrhosis in patients with coinfection of HCV and schistosomiasis as compared to biopsy. The addition of antischistosomal Ab to APRI did not improve sensitivity for predicting the degree of cirrhosis. | Moutaz Derbala Mohammed Elshiekh Elbadri Aliaa Mohamed Amer Saad Al Kaabi Khaleel Hassan Sultan Yasser Medhat Kamel Eman Hassan Satti Elsayed Tony Yervant Avades Prem Chandra Fatma M Shebl | 2015 | World Journal of Gastroenterology2015，21，46： | 2 |

| 3 | Digestive system involvement and clinical outcomes among COVID-19 patients:A retrospective cohort study from Qatar显示文摘BACKGROUND Coronavirus disease 2019(COVID-19)caused by the severe acute respiratory syndrome coronavirus 2 virus most commonly presents with respiratory symptoms.While gastrointestinal(GI)manifestations either at presentation or during hospitalization are also common,their impact on clinical outcomes is controversial.Some studies have described worse outcomes in COVID-19 patients with GI symptoms,while others have shown either no association or a protective effect.There is a need for consistent standards to describe GI symptoms in COVID-19 patients and to assess their effect on clinical outcomes,including mortality and disease severity.AIM To investigate the prevalence of GI symptoms in hospitalized COVID-19 patients and their correlation with disease severity and clinical outcomes.METHODS We retrospectively reviewed 601 consecutive adult COVID-19 patients requiring hospitalization between May 1-15,2020.GI symptoms were recorded at admission and during hospitalization.Demographic,clinical,laboratory,and treatment data were retrieved.Clinical outcomes included all-cause mortality,disease severity at presentation,need for intensive care unit(ICU)admission,development of acute respiratory distress syndrome,and need for mechanical ventilation.Multivariate logistic regression model was used to identify independent predictors of the adverse outcomes.RESULTS The prevalence of any GI symptom at admission was 27.1%and during hospitalization was 19.8%.The most common symptoms were nausea(98 patients),diarrhea(76 patients),vomiting(73 patients),and epigastric pain or discomfort(69 patients).There was no difference in the mortality between the two groups(6.21%vs 5.5%,P=0.7).Patients with GI symptoms were more likely to have severe disease at presentation(33.13%vs 22.5%,P<0.001)and prolonged hospital stay(15 d vs 14 d,P=0.04).There was no difference in other clinical outcomes,including ICU admission,development of acute respiratory distress syndrome,or need for mechanical ventilation.Drugs associated with the development of GI symptoms during hospitalization were ribavirin(diarrhea 26.37%P<0.001,anorexia 17.58%,P=0.02),hydroxychloroquine(vomiting 28.52%,P=0.009)and lopinavir/ritonavir(nausea 32.65%P=0.049,vomiting 31.47%P=0.004,and epigastric pain 12.65%P=0.048).In the multivariate regression analysis,age>65 years was associated with increased mortality risk[odds ratio(OR)7.53,confidence interval(CI):3.09-18.29,P<0.001],ICU admission(OR:1.79,CI:1.13-2.83,P=0.012),and need for mechanical ventilation(OR:1.89,CI:1.94-2.99,P=0.007).Hypertension was an independent risk factor for ICU admission(OR:1.82,CI:1.17-2.84,P=0.008)and need for mechanical ventilation(OR:1.66,CI:1.05-2.62,P=0.028).CONCLUSION Patients with GI symptoms are more likely to have severe disease at presentation;however,mortality and disease progression is not different between the two groups. | Muhammad Umair Khan Kamran Mushtaq Deema Hussam Alsoub Phool Iqbal Fateen Ata Hammad Shabir Chaudhry Fatima Iqbal Girisha Balaraju Muna A Al Maslamani Betsy Varughese Rajvir Singh Khalid Al Ejji Saad Al Kaabi Yasser Medhat Kamel Adeel Ajwad Butt | 2021 | World Journal of Gastroenterology2021，27，46： | 1 |
