| 1 | Isolation and diagnosis of Helicobacter pylori by a new method: Microcapillary culture显示文摘AIM:To investigate the performance of the microcapillary culture method(MCM) in Helicobacter pylori(H.pylori) isolation and diagnosis.METHODS:Microcapillary culture(MC),classical culture(CC),rapid urease(CLO) test,and histopathologic examination(HE) were performed with biopsy samples.Homogenized biopsy samples were loaded into capillary tubes and incubated for 48 h at 37 ℃ without providing a microaerophilic environment.Additionally,three or four loops of the homogenized sample were inoculated in a ready-to-use selective medium(Becton Dickinson,Helicobacter Agar,Modified) specific for the isolation of H.pylori and incubated at 37 ℃ in a microaerophilic atmosphere provided by Campy Gen(Becton Dickinson,Gas Pack).Bacteria reproducing in microcapillary tubes were evaluated in an inverted microscope and also were evaluated after performing a CC with the content.Results obtained by CC,CLO test,and HE were compared with those of MC.The diagnostic performances of the methods used in this study were evaluated for specificity,sensitivity,positive predictive value(PPV),negative predictive value(NPV),and CI.RESULTS:H.pylori was found positive by CLO test +HE and/or CC culture in 26 patient antrum and corpus biopsy samples.In 25(25/26) patient biopsy samples,H.pylori was isolated by MCM,whereas in only 14(14/26) patient biopsy samples,H.pylori was isolatedby CC.CLO test and HE were found positive in 17(17/26) patient biopsy samples.Comparing the results of the isolation of H.pylori by MCM,CC,CLO test,and HE,the sensitivity of the MCM was found as 96%,the specificity as 80%,the PPV as 83%,the NPV as 95%,and the 95%CI as 0.76(χ2 =31.51,P < 0.01) whereas the sensitivity of the CC was found as 54%(χ2 =19.15,P < 0.01),and the sensitivity of the CLO test and HE were found as 65%(χ2 =25.26,P < 0.01).CONCLUSION:This new microcapillary cultivation method for H.pylori has high diagnostic sensitivity compared with CC,HE,and CLO tests. | Adil M Allahverdiyev Melahat Bagirova Reyhan Caliskan Hrisi Bahar Tokman Hayat Aliyeva Gokce Unal Olga Nehir Oztel Emrah Sefik Abamor Hilal Toptas Pelin Yuksel Fatma Kalayci Mustafa Aslan Yusuf Erzin Kadir Bal Bekir S Kocazeybek | 2015 | World Journal of Gastroenterology2015，21，9： | 2 |
| 2 | 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 | Effectiveness of hepatitis B virus vaccination program in Egypt:Multicenter national project显示文摘AIM:To assess the effectiveness of hepatitis B virus(HBV) vaccination program among fully vaccinated children.METHODS:A national community based crosssectional study was carried out in 6 governorates representing Egypt. A total of 3600 children aged from 9 mo to 16 years who were fully vaccinated with HBV vaccine during infancy were recruited. Face to face interviews were carried out and sera were evaluated for hepatitis B surface antigen(HBsA g),anti-HBV core antibodies(total) and quantitative detection of hepatitis B surface antibody using enzyme linked immunoassays techniques. Samples positive to HBs Ag/anti-HBV core antibodies were subjected to quantitative HBV-DNA detection by real time polymerase chain reaction with 3.8 IU/L detection limit. RESULTS:Sero-protection was detected among 2059 children(57.2%) with geometric mean titers 75.4 ± 3.6 IU/L compared to 3.1 ± 2.1 IU/L among nonseroprotected children. Multivariate logistic analysis revealed that older age and female gender were the significant predicting variables for having non seroprotective level,with adjusted odds ratio 3.3,9.1and 14.2 among children aged 5 to < 10,10 to < 15 and ≥ 15 years respectively compared to those < 5 years and 1.1 among girls compared to boys with P < 0.01. HBs Ag was positive in 0.11% and breakthrough infection was 0.36% and 0.39% depending on positivity of anti-HBc and DNA detection respectively. The prevalence of HBV infection was significantly higher among children aged ≥ 7 years(0.59%) compared to 0.07% among younger children with odds ratio equal to 8.4(95%CI:1.1-64.2) and P < 0.01.The prevalence was higher among girls(0.48%) than boys(0.29%) with P > 0.05. C ON C LU S I ON :T he E gy pt ian c ompuls or y H B V vaccination program provides adequate protection. Occult HBV infection exists among apparently healthy vaccinated children. Adherence to infection control measures is mandatory. | Iman I Salama Samia M Sami Zeinab Nabil Ahmed Said Manal H El-Sayed Lobna A El Etreby Thanaa M Rabah Dalia M Elmosalami Amany T Abdel Hamid Somaia I Salama Aida M Abdel Mohsen Hanaa M Emam Safaa M Elserougy Amal I Hassanain Naglaa F Abd Alhalim Fatma A Shaaban Samia A Hemeda Nihad A Ibrahim Ammal M Metwally | 2015 | World Journal of Hepatology2015，7，22： | 2 |
| 4 | 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 |
