BackgroundDespite national guidelines emphasizing the importance of vaccination or documenting immunity to hepatitis A virus and hepatitis B virus for patients with chronic liver disease, the success of adhering to these recommendations is suboptimal. We aim to evaluate the prevalence of vaccination or documented reactivity to hepatitis A antibody and hepatitis B surface antibody among US adults with chronic liver disease.MethodsUsing 2011-2018 National Health and Nutritional Examination Survey data, adults with nonalcoholic fatty liver disease, alcoholic liver disease, hepatitis B, and hepatitis C were evaluated to determine prevalence of vaccination (self-reported completion) and hepatitis A antibody reactivity or hepatitis B surface antibody reactivity.ResultsOverall prevalence of vaccination or hepatitis A antibody reactivity was lowest among individuals with nonalcoholic fatty liver disease (60.8%; 95% confidence interval [CI], 57.9-63.6) and alcoholic liver disease (61.8%; 95% CI, 59.0-64.6), and highest among individuals with hepatitis B (82.9%; 95% CI, 76.8-89.0). Prevalence of vaccination or hepatitis B surface antibody reactivity was much lower: 38.6% (95% CI, 35.7-41.4) in nonalcoholic fatty liver disease, 40.7% (95% CI, 34.4-47.0) in chronic hepatitis C virus, and 47.1% (95% CI, 44.3-49.9) in alcoholic liver disease.ConclusionAmong US adults with chronic liver disease, prevalence of vaccination or documented reactivity to hepatitis A antibody and hepatitis B surface antibody was alarmingly low. These observations are particularly concerning given that underlying chronic liver disease increases risks of severe liver injury and decompensation from acute hepatitis A or hepatitis B infections.Copyright © 2021 Elsevier Inc.
