Abstract

BACKGROUND: Limited information exists regarding the distribution of disease phases, treatment prescription and severe liver disease among patients with chronic hepatitis B (CHB) in US general healthcare settings.

AIM: To determine the distribution of disease phases, treatment prescription and severe liver disease among patients with CHB in general US healthcare settings.

METHODS: We analysed demographic and clinical data collected during 2006-2013 from patients with confirmed CHB in the Chronic Hepatitis Cohort Study, an observational cohort study involving patients from healthcare organisations in Michigan, Pennsylvania, Oregon and Hawaii. CHB phases were classified according to American Association for the Study of Liver Disease guidelines.

RESULTS: Of 1598 CHB patients with ≥12 months of follow-up (median 6.3 years), 457 (29%) were immune active during follow-up [11% hepatitis B e antigen (HBeAg)-positive, 16% HBeAg-negative, and 2% HBeAg status unknown], 10 (0.6%) were immune tolerant, 112 (7%) were inactive through the duration of follow-up and 886 (55%) were phase indeterminate. Patients with cirrhosis were identified within each group (among 21% of immune active, 3% of inactive and 9% of indeterminate phase patients) except among those with immune-tolerant CHB. Prescription of treatment was 59% among immune active patients and 84% among patients with cirrhosis and hepatitis B virus (HBV) DNA >2000 IU/mL.

CONCLUSIONS: Approximately, one-third of the cohort had active disease during follow-up; 60% of eligible patients were prescribed treatment. Our findings underscore the importance of ascertainment of fibrosis status in addition to regular assessment of ALT and HBV DNA levels.
