AIM: To evaluate the accuracy of specific biochemical markers for the assessment of hepatic fibrosis in patients with chronic hepatitis C virus (HCV) infection. METHODS: One hundred and fifty-four patients with chronic HCV infection were included in this study; 124 patients were non-cirrhotic, and 30 were cirrhotic. The following measurements were obtained in all patients: serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin, total bilirubin, prothrombin time and concentration, complete blood count, hepatitis B surface antigen (HBsAg), HCVAb, HCV-RNA by quantitative polymerase chain reaction, abdominal ultrasound and ultrasonic-guided liver biopsy. The following ratios, scores and indices were calculated and compared with the results of the histopathological examination: AST/ALT ratio (AAR), age platelet index (API), AST to platelet ratio index (APRI), cirrhosis discriminating score (CDS), Pohl score, G teborg University Cirrhosis Index (GUCI). RESULTS: AAR, APRI, API and GUCI demonstrated good diagnostic accuracy of liver cirrhosis (80.5%, 79.2%, 76.6% and 80.5%, respectively); P values were: 0.05). In addition, we found significant correlations for the AAR, APRI, API, GUCI and Pohl score between the non-cirrhotic (F0, F1, F2, F3) and cirrhotic (F4) groups (P values: 0.05). CONCLUSION: The use of AAR, APRI, API, GUCI and Pohl score measurements may decrease the need

Worldwide, more than one million people die each year from hepatitis C virus(HCV) related diseases, and over 300 million people are chronically infected with hepatitis B or C. Egypt used to be on the top of the countries with heavy HCV burden. Some countries are making advances in elimination of HCV, yet multiple factors preventing progress; remain for the majority. These factors include lack of global funding sources for treatment, late diagnosis, poor data, and inadequate screening. Treatment of HCV in Egypt has become one of the top national priorities since 2007. Egypt started a national treatment program intending to provide cure for Egyptian HCV-infected patients. Mass HCV treatment program had started using Pegylated interferon and ribavirin between 2007 and 2014. Yet, with the development of highly-effective direct acting antivirals(DAAs) for HCV, elimination of viral hepatitis has become a real possibility. The Egyptian National Committee for the Control of Viral Hepatitis did its best to provide Egyptian HCV patients with DAAs. Egypt adopted a strategy that represents a model of care that could help other countries with high HCV prevalence rate in their battle against HCV. This review covers the effects of HCV management in Egyptian real life settings and the outcome of different treatment protocols. Also, it deals with the current and future strategies for HCV prevention and screening as well as the challenges facing HCV elimination and the prospect of future eradication of HCV.

Towards an easier pleurodesis: Ultrasound-guided iodopovidone sclerotherapy in cirrhotic patients with hepatic hydrothorax

引用

Open Journal of Gastroenterology 2013年第3期3卷 196-201页

作者： Ahmed M. Abdelhafeez Mohammed W. Zakaria Waleed F. Fathalah dalia omran Chest Department Faculty of Medicine Cairo University Cairo Egypt Endemic Medicine and Hepatology Department Faculty of Medicine Cairo University Cairo Egypt

Background and Aim: Hepatic hydrothorax is one of the complications encountered in end stage liver disease. Pleural drainage carries the risk of massive protein and electrolyte depletion as well as the risk of bleeding and hepatic encephalopathy. Pleurodesis following pleural aspiration decreases the chance of pleural effusion recurrence, and has been a widely used long-standing method of controlling recurrent pleural effusions. The aim of this study is to evaluate the effect of pleurodesis using ultrasound-guided iodopovidone sclerotherapy in hepatic hydrothorax. Patients and Methods: This prospective study included 56 patients with clinical, laboratory and radiological evidence of liver cirrhosis and symptomatic right sided hepatic hydrothorax. All patients were subjected to repeated thoracentesis. Ten ml of lidocaine 2% were injected in the pleural space followed by 20 ml of iodopovidone. The follow-up was done after 3 months. Results: The sclerotherapy procedure was successful in 40 out of 56 cases (71.4%), and the success rate was 66.7% in massive effusion and reached 80% in moderate effusion. Twenty eight patients (50%) had to repeat the procedure for a second time, sixteen of which (28.6%) failed despite the second trial and twelve cases (21.4%) showed no fluid reaccumulation. Conclusion: Ultrasound-guided iodopovidone sclerotherapy is an effective approach for a successful pleurodesis in hepatic hydrothorax.

Aim: Liver disease is a leading cause of morbidity and mortality among Egyptians. The major cause is infection with HCV, with 70 000 up to 140 000 newly reported cases annually. The objectives of this study were to determine the prevalence of anti-HCV antibodies among household contacts of HCV index cases and to identify the possible risk factors of transmission of HCV among Egyptian families. Material and Methods: The present external pilot study (double centre study) was performed on a convenient sample of 125 index cases and their 321 household family contacts recruited from Mansoura & Cairo University where 2 questionnaires were used to collect data from the index & their related contacts. The all were exposed to clinical examinations, routine laboratory testing & screening for the prevalence of Anti-HCV antibodies. Results: The prevalence of anti-HCV seropositivity among household contacts of index cases was found to be 13.7% which husbands of female index cases ranked first followed by wives of male index cases (36.36% versus 17.86% respectively,
