| 1 | Autologous CD34^+ and CD133^+ stem cells transplantation in patients with end stage liver disease显示文摘AIM:To assess the utility of an autologous CD34 + and CD133 + stem cells infusion as a possible therapeutic modality in patients with end-stage liver diseases.METHODS:One hundred and forty patients with endstage liver diseases were randomized into two groups.Group 1,comprising 90 patients,received granulocyte colony stimulating factor for five days followed by autologous CD34 + and CD133 + stem cell infusion in the portal vein.Group 2,comprising 50 patients,received regular liver treatment only and served as a control group.RESULTS:Near normalization of liver enzymes and improvement in synthetic function were observed in 54.5% of the group 1 patients;13.6% of the patients showed stable states in the infused group.None of the patients in the control group showed improvement.No adverse effects were noted.CONCLUSION:Our data showed that a CD34 + and CD133 + stem cells infusion can be used as supportive treatment for end-stage liver disease with satisfactory tolerability. | Hosny Salama Abdel-Rahman N Zekri Abeer A Bahnassy Eman Medhat Hanan A Halim Ola S Ahmed Ghada Mohamed Sheren A Al Alim Ghada M Sherif | 2010 | World Journal of Gastroenterology2010，16，42： | 16 |
| 2 | Development of an Arabic version of the National Eye Institute Visual Function Questionnaire as a tool to study eye diseases patients in Egypt显示文摘AIM:To develop and test an Arabic version of the National Eye Institute Visual Function Questionnaire-25(NEI-VFQ-25).METHODS:NEI-VFQ-25 was translated into Arabic according to WHO translation guidelines. We enrolled adult consenting patients with bilateral chronic eye diseases who presented to 14 hospitals across Egypt from October to December 2012, and documented their clinical findings. Psychometric properties were then tested using STATA.RESULTS:We recruited 379 patients, whose mean age was(54.5±15)y. Of 46.2% were males, 227 had cataract,31 had glaucoma, 23 had retinal detachment, 37 had diabetic retinopathy, and 61 had miscellaneous visual defects. Non-response rate and the floor and ceiling numbers of the Arabic version(ARB-VFQ-25) were calculated. Internal consistency was high in all subscales(except general health), with Cronbach-α ranging from0.702-0.911. Test-retest reliability was high(intraclass correlation coefficient 0.79).CONCLUSION:RB-VFQ-25 isareliableandvalidtool for assessing visual functions of Arabic speaking patients. However, some questions had high non-response rates and should be substituted by available alternatives. Our results support the importance of including self-reported visual functions as part of routine ophthalmologic examination. | Nizar Saleh Abdelfattah Mohamed Amgad Ahmed A Salama Marina E Israel Ghada A Elhawary Ahmed E Radwan Mohamed M Elgayar Tamer M EL Nakhal Islam T Elkhateb Heba A Hashem Doha K Embaby Amira A Elabd Reem K Elwy Magdi S Yacoub Hamdy Salem Mohamed Abdel-Baqy Ahmad Kassem | 2014 | International Journal of Ophthalmology(English edition)2014，7，5： | 8 |
| 3 | Serum complement C4a and its relation to liver fibrosis in children with chronic hepatitis C显示文摘AIM:To evaluate serum complement C4a and its relation to liver fibrosis in children with chronic hepatitis C virus(HCV)infection.METHODS:The study included 30 children with chronic HCV infection before receiving antiviral therapy.Chronic HCV infection was defined by positive anti-HCV,a positive polymerase chain reaction for HCV-RNA for more than 6 mo with absence of any associated liver disease.A second group of 30 age-and sex-matched healthy children served as controls.Serum C4a levels were measured by enzyme-linked immunosorbent assay.Liver fibrosis stage and inflammatory grade were assessed using Ishak scoring system.Serum C4a levels were compared according to different clinical,laboratory and histopathological parameters.Statistical significance for quantitative data was tested by MannWhitney U non-parametric tests.For qualitative data,significance between groups was tested by 2test.Correlation was tested by Spearman’s test.Results were considered significant if P value≤0.05.RESULTS:The age of the patients ranged from 3.5to 18 years and that of controls ranged from 4 to 17years.C4a mean levels were merely lower in patients(153.67±18.69 mg/L)than that in the controls(157.25±11.40 mg/L)with no statistical significance(P=0.378).It did not differ significantly in patients with elevated vs those with normal transaminases(152.25±16.62 vs 155.36±21.33;P=0.868)or with different HCV viremia(P=0.561).Furthermore,there was no statistical significant difference in serum levels between those with no/mild fibrosis and those with moderate fibrosis(154.65±20.59 vs 152.97±17.72;P=0.786)or minimal and mild activity(155.1±21.93 vs 152.99±17.43;P=0.809).Though statistically not significant,C4a was highest in fibrosis score 0(F0),decreasing in F1 and F2 to be the lowest in F3.When comparing significant fibrosis(Ishak score≥3)vs other stages,C4a was significantly lower in F3 compared to other fibrosis scores(143.55±2.33 mg/L vs 155.26±19.64 mg/L;P=0.047)and at a cutoff value of less than 144.01 mg/L,C4a could discriminate F3 with 76.9%sensitivity and75%specificity from other stages of fibrosis.CONCLUSION:Serum complement C4a did not correlate with any of transaminases,HCV viremia or with the histopathological scores.Although C4a decreased with higher stages of fibrosis,this change was not significant enough to predict individual stages of fibrosis.Yet,it could predict significant fibrosis with acceptable clinical performance. | Behairy E Behairy Ghada M El-Mashad Ragab S Abd-Elghany Enas M Ghoneim Mostafa M Sira | 2013 | World Journal of Hepatology2013，5，8： | 4 |
| 4 | Annexin A2 as a biomarker for hepatocellular carcinoma in Egyptian patients显示文摘AIM To investigate the clinical utility of serum annexin A2(ANXA2) as a diagnostic marker for early hepatocellular carcinoma(HCC).METHODS This study was performed in HCC Clinic of Ain Shams University Hospitals, Cairo, Egypt and included: Group 1: Fifty patients with early stage HCC(Barcelona Clinic Liver Cancer stage A); Group 2: Twenty five patients with chronic liver disease; and Control Group: Fifteen healthy, age-and sex-matched subjects who were seronegative for viral hepatitis markers. The followinglaboratory investigations were done: Viral hepatitis markers [hepatitis B surface antigen and hepatitis C virus(HCV) antibodies], HCV RNA in HCV antibody-positive patients, serum alpha fetoprotein(AFP), and serum ANXA2 levels.RESULTS In this study, 88% of HCC patients(n = 44) were HCVpositive, while HBV infection represented only 8% of all HCC patients(n = 4); and two patients were negative for both viral markers. A highly significant difference was found between patients with HCC and chronic liver disease as well as controls with regard to serum ANXA2 levels(130, IQR 15-240; 15, IQR 15-17; and 17, IQR 15-30 ng/m L, respectively). The area under the curve of ANXA2 was 0.865; the cut-off value was established to be 18 ng/mL with a diagnostic sensitivity of 74% and a specificity of 88%, while the sensitivity and specificity of AFP at the cut-off value of 200 ng/dL were 20% and 100%, respectively.CONCLUSION Serum ANXA2 may serve as a biomarker for the early detection of HCC. | Mohamed K Shaker Hanzada I Abdel Fattah Ghada S Sabbour Iman F Montasser Sara M Abdelhakam Eman El Hadidy Rehab Yousry Ahmed K El Dorry | 2017 | World Journal of Hepatology2017，9，9： | 4 |
| 5 | M2BPGi for assessing liver fibrosis in patients with hepatitis C treated with direct-acting antivirals显示文摘BACKGROUND Assessing liver fibrosis is important for predicting the efficacy of direct-acting antivirals(DAAs)and patient prognosis.Non-invasive techniques to assess liver fibrosis are becoming important.Recently,serum Mac-2 binding protein glycosylation isomer(M2BPGi)was identified as a non-invasive marker of liver fibrosis.AIM To investigate the diagnostic accuracy of M2BPGi in assessing liver fibrosis in patients with chronic hepatitis C(CHC)treated with DAAs.METHODS From December 2017 to August 2018,80 treatment-naive adult patients with CHC who were eligible for DAAs therapy were consecutively enrolled in this observational cohort study.For 12 weeks,65 patients were treated with sofosbuvir/daclatasvir,and 15 patients were treated with sofosbuvir/daclatasvir and a weight-based dose of ribavirin at knowledge and technology association for hepatitis C management clinic,Cairo,Egypt.We measured serum M2BPGi levels,PAPAS index,fibrosis-4(FIB-4)score and liver stiffness measurements(LSM)at baseline and 12 weeks after the end of treatment.Serum M2BPGi levels were measured using enzyme-linked immunosorbent assay.RESULTS All patients achieved sustained virologic response(SVR12)(100%).Serum M2BPGi levels,LSM,FIB-4 score and PAPAS index decreased significantly at SVR12(P<0.05).Serum M2BPGi levels correlated positively with LSM at baseline and SVR12(P<0.001).At baseline,compared with the FIB-4 score and PAPAS index,M2BPGi was the best marker to distinguish patients with grade F4 fibrosis(AUC=0.801,P<0.001),patients with grade F2 from grade F0-1 fibrosis(AUC=0.713,P=0.012),patients with grade F3-4 from grade F0-2 fibrosis(AUC=0.730,P<0.001),and patients with grade F2-4 from grade F0-1 fibrosis(AUC=0.763,P<0.001).At SVR12,M2BPGi had the greatest AUCs for differentiating patients with grade F4 fibrosis(AUC=0.844,P<0.001),patients with grade F3 from grade F0-2 fibrosis(AUC=0.893,P=0.002),patients with grade F3-4 from grade F0-2 fibrosis(AUC=0.891,P<0.001),and patients with grade F2-4 from grade F0-1 fibrosis(AUC=0.750,P<0.001).CONCLUSION M2BPGi is a reliable marker for the non-invasive assessment and prediction of liver fibrosis regression in patients with CHC who achieved an SVR with DAAs therapy. | Shereen A Saleh Mohamed M Salama Marwan M Alhusseini Ghada A Mohamed | 2020 | World Journal of Gastroenterology2020，26，21： | 3 |
| 6 | Regular arrangement of collecting venules:Does patient age affect its accuracy?显示文摘AIM:To address the diagnostic value of the regular arrangement of collecting venules(RAC)among old age patients. METHODS:A total of 390 consecutive patients whose Helicobacter pylori(H.pylori)status was known and who received upper gastrointestinal endoscopy,were retrospectively studied for the presence or absence of RAC as well as gastric mucosal atrophy.The sensitivity, specificity,positive predictive value,negative predic-tive value and accuracy of RAC to detect normal gastric mucosa were assessed and were compared among two different age groups of patients. RESULTS:The mean age±standard deviation(SD)of included patients(n=390),was 62.9±13 years.The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of RAC to detect normal gastric mucosa were 91.7%,66.1%,18.8%,99%and 68.1%respectively.Although the sensitivity,specificity,positive predictive value,negative predictive value and accuracy of RAC among patients<60 years(n= 139)was 94.7%,71.2%,46.2%,98.1%and 76.1%,respectively,it was 80%,64.3%,5.1%,93%and 64.6%, respectively,among patients≥60 years(n=251). Younger Patients(<60 years),have highly significant rates of RAC sensitivity,positive predictive value,and accuracy(P≤0.001,≤0.001 and≤0.02,respectively).Older patients had highly significant rates of H. pylori infection and gastric mucosal atrophy(P≤0.01). CONCLUSION:Although RAC is a valuable sign for real-time identification of normal gastric mucosa,its accuracy seems to be affected by the patient's age. | Alshimaa Alaboudy Ashraf Elbahrawy Shigemi Matsumoto Ghada M Galal Tsutomu Chiba | 2011 | World Journal of Gastrointestinal Endoscopy2011，3，6： | 2 |

| 19 | Role of endoscopic ultrasound and cyst fluid tumor markers in diagnosis of pancreatic cystic lesions显示文摘BACKGROUND Pancreatic cystic lesions(PCLs) are common in clinical practice. The accurate classification and diagnosis of these lesions are crucial to avoid unnecessary treatment of benign lesions and missed opportunities for early treatment of potentially malignant lesions.AIM To evaluate the role of cyst fluid analysis of different tumor markers such as cancer antigens [e.g., cancer antigen(CA)19-9, CA72-4], carcinoembryonic antigen(CEA), serine protease inhibitor Kazal-type 1(SPINK1), interleukin 1 beta(IL1-β), vascular endothelial growth factor A(VEGF-A), and prostaglandin E2(PGE2)], amylase, and mucin stain in diagnosing pancreatic cysts and differentiating malignant from benign lesions.METHODS This study included 76 patients diagnosed with PCLs using different imaging modalities. All patients underwent endoscopic ultrasound(EUS) and EUS-fine needle aspiration(EUS-FNA) for characterization and sampling of different PCLs.RESULTS The mean age of studied patients was 47.4 ± 11.4 years, with a slight female predominance(59.2%). Mucin stain showed high statistical significance in predicting malignancy with a sensitivity of 87.1% and specificity of 95.56%. It also showed a positive predictive value and negative predictive value of 93.1% and 91.49%, respectively(P < 0.001). We found that positive mucin stain, cyst fluid glucose, SPINK1, amylase, and CEA levels had high statistical significance(P < 0.0001). In contrast, IL-1β, CA 72-4, VEGF-A, VEGFR2, and PGE2 did not show any statistical significance. Univariate regression analysis for prediction of malignancy in PCLs showed a statistically significant positive correlation with mural nodules, lymph nodes, cyst diameter, mucin stain, and cyst fluid CEA. Meanwhile, logistic multivariable regression analysis proved that mural nodules, mucin stain, and SPINK1 were independent predictors of malignancy in cystic pancreatic lesions.CONCLUSION EUS examination of cyst morphology with cytopathological analysis and cyst fluid analysis could improve the differentiation between malignant and benign pancreatic cysts. Also, CEA, glucose, and SPINK1 could be used as promising markers to predict malignant pancreatic cysts. | Hussein Hassan Okasha Abeer Abdellatef Shaimaa Elkholy Mohamad-Sherif Mogawer Ayman Yosry Magdy Elserafy Eman Medhat Hanaa Khalaf Magdy Fouad Tamer Elbaz Ahmed Ramadan Mervat E Behiry Kerolis Y William Ghada Habib Mona Kaddah Haitham Abdel-Hamid Amr Abou-Elmagd Ahmed Galal Wael A Abbas Ahmed Youssef Altonbary Mahmoud El-Ansary Aml E Abdou Hani Haggag Tarek Ali Abdellah Mohamed A Elfeki Heba Ahmed Faheem Hani M Khattab Mervat El-Ansary Safia Beshir Mohamed El-Nady | 2022 | World Journal of Gastrointestinal Endoscopy2022，14，6： | 1 |
