Primary outcomePrimary: Anti-HBs Titres (IU/L) — 642; 385 Anti-HBS IU/L — p=0.02
Summary
(1) Due to missed childhood vaccination programs, the majority of adult patients with NAFLD in Canada do not have immunity to hepatitis B. (2) Adults with NAFLD who receive the HBV vaccine have reduced immunogenic responses in the setting of obesity (i.e., protective anti-HBs titres). Aims: (1) To determine the sero-prevalence of immunity against hepatitis B in a cohort of prospectively evaluated adult NAFLD patients. (2) To prospectively determine HBV vaccine responses (anti-HBs titres) in adult NAFLD patients.

Eligibility Criteria
Inclusion Criteria
- Subjects 18-60 years of age, who provide signed informed consent
- Diagnosis of NAFLD/NASH according to expert assessment (by imaging, TE, abnormal lab tests and/or liver biopsy)
- No evidence of prior infection or immunity to hepatitis B (negative HBsAg, anti-HBs, anti-HBc).
Exclusion Criteria
- Subjects 60 y will be excluded, due to effect of age and reduced response to HBV vaccination.
