Autoantibodies in HCV infected patients at Sharkia Governerate, Egypt

The aim of this study was to evaluate some immunological manifestations in chronic hepatitis C patients and to find out its relationship with liver pathology. The study included 109 positive HCV-RNA patients classified according to liver histopathology into three groups: Group I included 22 patients [G1S1], group II included 67 patients [G2S2] and group III included 20 patients [G3S3], where G = the degree of necro-inflammatory process and S = the stage of liver fibrosis. All patients were investigated for the presence of cryoglobulin, antineutrophil cytoplasmic [ANCA], anti-liver kidney microsomes [LKM], anti-double stranded DNA, [ds-DNA], anti-nuclear [ANA], anti-mitochondrial [AMA] and anti-smooth muscle [ASMA] autoantibodies. The high prevalence of autoantibodies in chronic HCV patients suggests that HCV may trigger an autoimmune reaction, but most probably do not indicate a distinct autoimmune mechanism. Cryoglobulins and ANCA may be considered as useful prognostic indicator for the increased risk of cirrhosis in chronic HCV patients. Follow up studies were recommended

HCV and associated concomitant infections at Sharkia Governorate Egypt

This study was performed on 109 cases divided into 6 groups according to the concomitant infection with hepatitis C virus [HCV]. The results proved that groups 1, 3 and 5 had a higher level of viremia than the other groups and a higher risk was found in these groups, as 56.4% and 34.6% were in G2S2 and G3S3, respectively. All cases of liver cell dysplasia and hepatocellular carcinoma in this study were seen in these groups. The study concluded that these factors play an important role in the progression of HCV infection. The death of the patients of this progressive condition occurs in younger age and due to liver failure more than to HCC

Non-invasive markers and predictors of severity of hepatic fibrosis in HCV patients at Sharkia Governorate, Egypt

This study included 109 patients with detectable hepatitis C virus [HCV] by real time PCR. The patients were classified into three different pathological stages and grades according to the new concept of histopathological staging and grading. The different clinical, biochemical, virological and ultrasonographic parameters were assessed and analyzed and the variables that showed a significant association with the histopathological staging and grading were included in the multivariate logistic regression analysis. The regression model revealed that platelet count, matrix metalloproteinase-9 [MMP-9], portal vein diameter, splenic longitudinal axis, alanine transaminase, aspartate transaminase and viral load added a significance to the model in a decreasing order of significance. From these findings, a new score ranged from 0-9 was generated. The score model was applied to the patients to assess its validity, where it proved to be accurate in discriminating patients with mild inflammation and fibrosis [sensitivity 81.8%, specificity 80.5% and accuracy 80.7%] and more accurate in detecting patients with cirrhosis [specificity 96.6%, sensitivity 80% and accuracy 93.6%], but less accurate in detecting patients with moderate to severe fibrosis [specificity 66.7%, sensitivity 68.7% and accuracy 67.9%]. Also, the results revealed that co-infection with schistosomiasis, old age >/45 years and positive history of blood transfusion as a source of infection were significantly associated with severe hepatic pathology

role of aflatoxin-contaminated food materials and HCV in developing hepatocellular carcinoma in Al-Sharkia Governorate, Egypt

In this study, the role of aflatoxin contamination in the onset of liver cancer in HCV-infected patients was studied. The quantitative identification of the possible aflatoxins contamination in six urban and eleven rural areas using high performance liquid chromatography technique revealed that corn, wheat, peanut, lupine "tennis", white rice, cowpea "lobiya", fava bean and brown rice showed a prevalence of AFB1 [64.7%, 53%, 53%, 47%, 47%, 41%, 29.4% and 29.4%, respectively]. A positive correlation was found between aflatoxin and positive HCV- PCR together with liver disease progression to G3S3, the indicative of hepatocellular carcinoma. Such correlation was not fully understood, but the oncogene amplification caused by HCV- infection may be aggravated by the consumption of aflatoxin contaminated raw food materials or their products
