Abstract Background Novel direct-acting antiviral agents have shown great efficacy and tolerability in HCV-monoinfected patients. However, data are lacking regarding their efficacy and safety in HIV/HCV-genotype (GT) 4-coinfected patients. Methods A single-centre, prospective study including HIV/HCV-GT 4-coinfected patients who were treated with sofosbuvir and daclatasvir (SOF/DCV) was conducted for 12 wk. Sustained virological response (SVR) at week 12 post-treatment (SVR12), adverse events (AEs) and changes in liver stiffness measurement (LSM) at SVR12 in comparison with baseline were evaluated. Results SVR12 was achieved in 46 of 50 patients (92%). No significant difference in SVR12 was noticed among patients who received antiretroviral therapy (ART) regimens compared with those who did not receive ART regimens or between those with insignificant fibrosis (<F2) and those with significant fibrosis (≥F2) (p=0.9 and p=0.3, respectively). AEs occurred in 45 (90%) patients. The most frequent AEs were fatigue, headache and nausea. No treatment-related serious AEs or deaths were reported. HIV control was not compromised. LSM, fibrosis 4 score and aspartate aminotransferase-to-platelet ratio index showed a significant decrease at SVR12 when compared with baseline (p=0.0004, p=0.0003 and p<0.0001, respectively). Logistic regression analysis showed no association between baseline variables and SVR12 while significant fibrosis (≥F2) was the only baseline variable that was significantly associated with improvement of LSM at SVR12. Conclusion SOF/DCV achieved a high SVR12 and was well-tolerated in HIV/HCV-GT 4-coinfected patients.

Abstract Background Hepatitis C virus (HCV) infection is a major cause of liver-related morbidity and mortality among thalassemic patients. Direct-acting antiviral agents (DAAs) are highly effective and well-tolerated by chronic HCV patients. Results The mean age of our patients was 29 years. Sustained virologic response (SVR) at 12 and 24 weeks was achieved in all patients (100%). The most common side effects were fatigue (18%), anemia (13.63%), and headache (4.5%). There was no statistically significant difference in the hemoglobin level before and after treatment (p = 0.48). There was a significant improvement in serum bilirubin and mean ALT levels after treatment compared to baseline data (p < 0.0005 each). Conclusions DAAs, namely, sofosbuvir plus daclatasvir or sofosbuvir plus ledipasvir, are effective and well-tolerated regimens in thalassemic patients with chronic HCV.

Abstract Background Chronic hepatitis C (CHC) is one of the most important comorbidities in patients with hereditary bleeding disorders (HBD). The present study aimed at evaluating the effectiveness of direct-acting antiviral agent (DAA)-based interferon-free HCV antiviral regimens in patients with HBD. Patients and methods The present study was performed on the patients with HBD and CHC between 2015 and 2019. Sofosbuvir-based interferon-free regimens with or without ribavirin were prescribed to treat HCV infection. The main endpoint of the study was to determine the sustained virologic response (SVR), assessed 12 weeks after the completion of treatment. Results A total of 147 patients with a mean age of 41.1 years were enrolled in the study; 4.1% of them were co-infected with HIV, 25.2% had cirrhosis, and 76.9% of them were diagnosed with hemophilia A. HCV genotype-1 includes the largest number (68.1%) of patients. 46.3% of patients were treatment-naïve and others had a treatment history with interferon-based regimens. Out of 147 patients, 15 patients were lost to follow-up during treatment or for SVR evaluation or discontinued treatment. 132 subjects completed treatment and were evaluated for SVR, 12 weeks after the completion of treatment. All of the patients achieved SVR 12 (SVR rate: 100%, 95% CI 97.2–100%). Conclusion Hepatitis C DAA-based regimens are the effective treatments for CHC in patients with HBD, regardless of the treatment modifiers such as previous treatment experience, cirrhosis, HIV co-infection, and HCV genotype.

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&lt;.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 Objectives To evaluate histologic changes occurring in patients having chronic hepatitis C and autoimmune hepatitis overlap (HCV-AIH), and who achieved virologic cure using direct-acting antiviral agents (DAA). Methods Characteristics of HCV-AIH patients who underwent paired liver biopsies before and after receiving DAA treatment from 2011 to 2018 were evaluated. Results Five HCV-AIH patients (three male; mean age, 60.4 years) underwent paired liver biopsies (average interval, 2.3 years) before and after achieving cure with DAA treatment. All patients showed virologic response, while four showed decreased inflammation, and three cases showed features of fibrosis regression. Immunohistochemical staining demonstrated significant decrease in plasma cell count in three patients (20.6 vs 11.9 plasma cells/high power field; P = .02, t test). Conclusions Histologic improvements in inflammation and fibrosis are noted in most HCV-AIH patients after DAA treatment, suggesting that the autoimmune component of the HCV-AIH overlap syndrome is merely a secondary phenomenon of viral infection.
