YH Yeo et al. Hepatology 2019; 69: 1385-97.  The prevalence of high risk individuals in the U.S. who are susceptible (not immune) to hepatitis B has decreased from 83% to 69% from 2003 to 2014.  That still leaves 64 million who would benefit from HBV vaccination.

M Sharma et al. Hepatology 2019; 69: 1657-75. This meta-analysis compared therapies for primary prevention of esophageal varices and concluded that nonselective beta-blocker (NSBB) monotherapy may decrease all-cause mortality and carried a lower risk of serious complications than variceal band ligation (VBL). However, the commentary (1382-84 by L Laine) reaches a different conclusion. “Current recommendations for primary prevention with VBL or NSBB or carvediolo still appear to be acceptable…using a shared decision-making approach” to weigh issue such as daily medication or periodic endoscopy.

J Nguyen et al. J Pediatr 2019; 207: 90-6. This study modeled the cost-effectiveness of early treatment with direct-acting antiviral therapy in adolescents with hepatitis C infection.  With pangenotypic agenst, the cost would be $10000 to $21000 per QALY gained.

S Trinh et al. Clin Gastroenterol Hepatol 2019; 17: 948-56. This retrospective hepatitis B study examined the changes in renal function between 239 tenofovir disoproxil fumarte (TDF) treated patients and 171 entecavir treated patients.  Key finding: TDF was not associated with higher risk of worsening renal function in this cohort with a mean followup of 43-46 months in patients with baseline normal renal function.  In patients with renal impairment, deterioration of renal function was noted in TDF-treated patients.  Thus, TDF should be avoided in patients with impaired renal function.
