IFNα-based antiviral therapy of hepatitis delta was independently associated with a lower likelihood for clinical disease progression. Durable undetectability of HDV RNA is a valid surrogate endpoint in the treatment of hepatitis delta. (Hepatology 2017;65:414-425).
This prospective study investigated viral and host markers after stopping long-term therapy with nucleos(t)ide analogues in noncirrhotic patients with hepatitis B e antigen-negative chronic hepatitis B. After stopping therapy, 13 of 15 patients experienced a virological relapse. Rebound of hepatitis B virus DNA and hepatitis B core-related antigen was associated with induction of plasma tumor necrosis factor, interleukin (IL) 10 , IL-12p70, CXCL10 and subsequent decline in hepatitis B surface antigen (HBsAg), with 20% HBsAg loss after long-term follow-up. The peak levels of hepatitis B virus DNA and hepatitis B core-related antigen after cessation of therapy were positively correlated with the level of HBsAg decline at week 48. Thus, stopping or interrupting NA treatment should be further investigated as a strategy to accelerate HBsAg loss.
A significant number of patients are at risk for DDIs if treated with the recently approved DAA regimens. A careful evaluation of potential DDI is essential to prevent adverse effects or unnecessary risk of treatment failure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
