ABSTRACT
Background:
Patients with chronic liver disease (CLD) are more likely to have severe morbidity and mortality due to superimposed acute or chronic hepatitis B virus (HBV) infection and should receive routine vaccination against the virus. Heplisav-B is a two-dose, inactivated, yeast-derived vaccine that uses a novel immunostimulatory adjuvant. Our primary objective was to determine the efficacy of hepatitis B vaccination with Heplisav-B in patients with CLD.Methods:
This retrospective cohort analysis included patients ≥18 years old with CLD who received Heplisav-B from January 2018 to January 2021. All patients had anti-HBs <10 IU/L prior to vaccination and received two doses of Heplisav-B. Post-vaccination anti-HBs of ≥10 IU/L was considered successful vaccination. Basic demographic information, laboratory markers, and medical history were collected from the electronic health record.Results:
A total of 120 patients were included in analysis. The average age of patients was 59 years, 37% were female, and the most common etiology of liver disease was nonalcoholic fatty liver disease. Median days from 2nd vaccination to post-vaccination HBsAb levels was 121 days. 81/120 (67.5%) of patients had evidence of active immunity after receipt of Heplisav-B. On multivariable analysis, age >50 was associated with reduced odds of successful vaccination (OR =0.19, 95% CI 0.03-0.76).Conclusions:
In patients with CLD, Heplisav-B's overall efficacy (67.5%) is greater than reports of Engerix-B (33-45%), and thus is an effective hepatitis B vaccine in this patient population, particularly in cirrhotic patients. Further studies regarding this vaccine are needed in patients with CLD and after liver transplantation.
