    Hepatitis B Virus Reactivation in Cancer Patients Receiving Direct-Acting Antivirals for Hepatitis C Virus Infection
    (Wiley, 2021) Pritchard, Haley; Hwang, Jessica P.; Angelidakis, Georgios; Yibirin, Marcel; Wang, Lan; Miller, Ethan; Torres, Harrys A.; Medicine, School of Medicine
    Direct-acting antivirals (DAAs) against hepatitis C virus (HCV) infection can cause hepatitis B virus (HBV) reactivation in HBV/HCV co-infected patients. Cancer patients undergoing immunosuppressant treatment or chemotherapy are at risk for HBV reactivation. To our knowledge, no prospective studies have examined the risk of HBV reactivation during DAA treatment for HCV infection in cancer patients with HBV/HCV co-infection. Here, we report the results of one such study. In a prospective observational study, we enrolled HCV-infected cancer patients undergoing DAA treatment at The University of Texas MD Anderson Cancer Center between January 2015 and March 2018. Data regarding demographics, cancer history, and prior HCV treatment history were collected. Patients were assessed for HBV status before DAA treatment and for HBV-related outcomes, including HBV reactivation, hepatitis flare, and HBV-associated hepatitis, during DAA treatment. Demographic and treatment variables were analyzed using descriptive statistics. One hundred sixty-six patients were analyzed. Forty-eight patients received systemic chemotherapy within 6 months before to 6 months after treatment with DAAs. Ledipasvir plus sofosbuvir was the most common DAA regimen, administered to 88 patients (53%). Fifty-one patients (31%) had past HBV infection, and 4 (2.4%) had chronic HBV infection. No patient experienced HBV reactivation, hepatitis flare, or HBV-associated hepatitis induced by DAA treatment. In HCV-infected cancer patients, DAA treatment is safe regardless of whether patients have past or chronic HBV infection. However, HBV screening is still recommended before the initiation of and during DAA treatment, as is anti-HBV prophylactic treatment in selected cases.

    Updated Clinical Guidelines on the Management of Hepatitis C Infection in Children
    (MDPI, 2024-02-16) Jarasvaraparn, Chaowapong; Hartley, Christopher; Karnsakul, Wikrom; Pediatrics, School of Medicine
    Children represent only a small proportion of those infected with the hepatitis C virus (HCV) compared to adults. Nevertheless, a substantial number of children have chronic HCV infection and are at risk of complications including cirrhosis, portal hypertension, hepatic decompensation with hepatic encephalopathy, and hepatocellular carcinoma in adulthood. The overall prevalence of the HCV in children was estimated to be 0.87% worldwide. The HCV spreads through the blood. Children born to women with chronic hepatitis C should be evaluated and tested for HCV due to the known risk of infection. The course of treatment for hepatitis C depends on the type of HCV. Currently, there are two pan-genotype HCV treatments (Glecaprevir/pibrentasvir and Sofosbuvir/velpatasvir) for children. We aim to review the updated clinical guidelines on the management of HCV infection in children, including screening, diagnosis, and long-term monitoring, as well as currently published clinical trials and ongoing research on direct acting antiviral hepatitis C treatment in children.
