Current epidemiology of hepatitis E virus infection in the United States: low seroprevalence in the National Health and Nutrition Evaluation Survey.

Unlabelled: Analysis of the National Health and Nutrition Evaluation Survey (NHANES) 1988-1994 dataset found a relatively high seroprevalence (21%) of hepatitis E virus (HEV) infection in the U.S. general population.

The changing epidemiology of hepatitis C virus infection in the United States: National Health and Nutrition Examination Survey 2001 through 2010.

Background & Aims: In light of the dramatically changing hepatitis C therapeutic landscape, knowledge of the current burden of HCV infection in the general population of the United States is critical.

Methods: The National Health and Nutrition Examination survey collects nationally representative data on HCV infection in the civilian population of the United States. Data from 2001 to 2010 were combined for this study.

Persistence and adherence to nucleos(t)ide analogue treatment for chronic hepatitis B.

Background & Aims: Long-term treatment with nucleos(t)ide analogues (NUCs) is associated with increasing rates of antiviral drug resistance. Medication adherence is important in preventing drug resistance. This study aimed to determine, first, the persistence rates and the adherence rates to NUCs in patients with chronic hepatitis B (CHB), and second, the factors associated with adherence.
