| 1 | Prevalence and risk factors of asymptomatic hepatitis C virus infection in Egyptian children显示文摘AIM: To identify the prevalence, risk factors and manifestations of asymptomatic hepatitis C virus (HCV) infection in Egyptian children. METHODS: Children at the age of 1-9 years were screened for HCV antibodies and alanine aminotransferase (ALT) levels. Every child with elevated ALT and/or detectable HCV antibodies was tested for HCV RNA by RT-PCR and compared with two negative controls for risk factors and signs and symptoms of liver disease.RESULTS: We screened 1042 children, six of them had elevated ALT, negative HCV antibody and positive RNA, likely representing acute hepatitis C cases. Fifteen children were HCV seropositive, 5 of them were HCV RNA positive. Asymptomatic HCV infection was present in 2.02% (positive results for either HCV antibodies or HCV-RNA or both). Symptoms such as diarrhea, abdominal pain, history of fatigue and school absence because of illness and risk factors such as dental care were significantly more common among HCV positive cases than among controls. None of the HCV positive children was diagnosed as having signs of advanced liver disease upon clinical or ultrasonographic examination. CONCLUSION: Asymptomatic HCV infection is detectable in 2.02% Egyptian children. | MS El-Raziky M El-Hawary G Esmat AM Abouzied N El-Koofy N Mohsen S Mansour A Shaheen M Abdel Hamid H El-Karaksy | 2007 | World Journal of Gastroenterology2007，13，12： | 4 |
| 2 | 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 |
