CROI 2019: highlights of viral hepatitis

Top Antivir Med. 2019 Apr;27(1):41-49.

Abstract

At the 2019 Conference on Retroviruses and Opportunistic Infections (CROI), there was a major focus on hepatitis C virus (HCV) elimination and improving each component of the hepatitis C care cascade. Many interventions showed promising improvements in diagnosis and linkage to care. Settings with robust access to direct-acting antivirals (DAAs) continue to demonstrate the role of HCV treatment as prevention. However, substantial barriers to accessing curative therapy remain. Reinfection after treatment presents an important barrier to elimination, particularly in some populations of men who have sex with men (MSM). MSM without HIV infection are at an elevated risk for sexual acquisition of HCV, and several studies reported HCV rates that were as high as those seen in MSM living with HIV. There was also a focus on HCV and HBV in pregnant women. Rates of HCV infection in women of child-bearing potential have increased, making prenatal diagnosis a priority. In the first study of HCV treatment during pregnancy, sofosbuvir/ledipasvir started at 28 weeks of gestation led to cure in 8 pregnant women. Hepatitis B virus (HBV)-active antiretrovirals are generally effective in suppressing HBV but have low rates of surface antigen loss despite long term treatment. Initial results from novel laboratory assessments of intrahepatic HBV viral infection events were presented, hopefully paving the way for more effective HBV treatment strategies to control and potentially cure HBV.
