Abstract Background and aims Widespread use of direct-acting antiviral (DAA) agents to treat patients with hepatitis C virus (HCV) infection has reduced the need for monitoring of HCV-RNA levels, because viral kinetics do not predict sustained virologic response (SVR) to these drugs. However, the performance of cheaper tests, such as the assay to quantify HCV core antigen (HCV Ag), has not been determined. This study was aimed at investigating the accuracy of the HCV Ag test in predicting which patients receiving DAAs will achieve SVR at week 12 (SVR12). Methods We performed a prospective study on 90 patients, chronically infected with HCV, receiving DAAs therapy from different NCCVH centers in Cairo during the period from August 2017 to June 2018. We collected blood samples and measured the levels of HCV core Ag and HCV-RNA at baseline and 12 weeks after end of treatment. We compared the ability of these assays to predict which patients would have SVR12. Results The median baseline level of HCV-RNA was 1688529.6 ± 994697.3 IU/ml (range, 312700 IU/ml to 3491100 IU/ml) and HCV Ag was 179.2 ± 83.5 pg/ml (range, 33.5 pg/ml to 315.6 pg/ml). HCV Ag became undetectable in 92.2% 12 weeks after the end of treatment. HCV-RNA became undetectable in 87.8% at the end of treatment (P<.0001). 79 out of 90 patients (87.8%) achieved an SVR12; the test for HCV Ag identified 63.6% of these patients. Conclusions Tests that measure HCV Ag monitor efficacy of DAA therapy for HCV infection as well as assays that measure HCV-RNA, and hence could be recommended for clinical practice.

Abstract Background Hepatitis C virus (HCV) is a major public health problem throughout the world. Acute HCV infection is asymptomatic in most cases, and only 15% of cases are symptomatic,but Chronic hepatitis C (CHC) shows a variable clinical course, ranging from mild histopathological changes to active hepatitis and the development of hepatic fibrosis, cirrhosis and HCC. The aim of this work is to detect accuracy of core antigen in Egyptian cirrhotic patients with HCV Infection treated with combination therapy of Sofosbuvir, Daclatasvir and Ribavirin as an alternative to PCR. Patients and methods: The study included20 Egyptian treatment-naïve chronic hepatitis C patients with cirrhosis (Cirrhosis was diagnosed on ultrasound basis) on Sofosbuvir, Daclatasvir and Ribavirin. Results Treatment with sofosbuvir plus Daclatasvir and Ribavirin for 12 weeks resulted in undetectable HCV RNA by PCR in 95% (19/20) of the patients at the end of treatment and only 5% (1/20) of the patients achieved SVR after 6 months not 3(both HCV RNA AND HCV Core Antigen tests were negative for all patients). Conclusion: In our study there was a correlation between HCV RNA and HCV core antigen results, so HCV core antigen can be used as an alternative marker to HCV RNA in treatment of HCV infected cirrhotic patients receiving Sofosbuvir, Daclatasvir and Ribavirin.during treatment and for monitoring its efficacy.

Objective. We studied the time course of hepatic dysfunction, seropositivity to hepatitis C virus (HCV) antibodies, viremia, and histologic evidence of hepatic injury to evaluate the course of HCV infection in children infected by blood transfusion. Patients and methods. Twenty-nine patients (ages 4 to 18 years) who underwent open-heart surgeries for congenital heart disease were grouped into three categories based on alterations in serum alanine aminotransferase (ALT) levels: Group A, acute infection; Group B, subacute infection; and Group C, chronic infection. Results. In Group C, all 13 patients had detectable HCV RNA in serum. In contrast, all patients in Group A had no detectable HCV RNA. In Group B, one of nine patients had detectable HCV RNA and two of four patients examined had persistent chronic hepatitis by histologic criteria. Antibodies directed against C100-3 antigen or core-antigen were more useful than second-generation HCV antibody assays in determining the relationship between viremia and immunologic response. Infection with HCV genotype II and the presence of higher HCV RNA copy numbers were associated with histologic evidence of hepatic damage. Conclusion. An abnormal ALT value is frequently associated with viremia, and biochemically resolved acute infection reflects clearance of HCV. However, a normal ALT does not always reflect an absence of hepatocyte damage and HCV replication in patients with subacute disease. The measures outlined in this study are useful indicators of disease activity during the chronic phase of post-transfusion HCV infection.
