Chronic hepatitis B can be a severe, long-term disease
Progression of chronic hepatitis B
The course of chronic hepatitis B is nonlinear and characterized by repeated liver cell destruction and regeneration over long periods of time.1-3
Effects of chronic hepatitis B on the liver2,4
HBV infection increases the risk of HCC through direct and indirect mechanisms, which may occur at early stages of tumor development and during any phase of HBV infection6-8
- Direct mechanisms revolve around the ability of HBV to integrate into the host's genome, leading to potentially carcinogenic chromosomal aberrations and protein expression6-8
- Indirect mechanisms center on the ability of HBV to induce continuous, recurring liver necroinflammation, which may culminate in the development of cirrhosis6,8
- Persons with chronic hepatitis B are at a 25- to 37-fold increased risk of HCC compared to non-infected people9
Real-world data indicate that using HBV DNA level >2000 IU/mL alone for patients without cirrhosis, and removing ALT and HBeAg treatment eligibility criteria, could impact long-term outcomes for patients with chronic hepatitis B9,10
Long-term considerations
For some patients, chronic hepatitis B is a lifelong disease that requires long-term or indefinite therapy.1,11-15
-
People with chronic hepatitis B are at risk for developing comorbidities, including diabetes, metabolic syndrome, and renal and bone conditions
- Risk for some comorbidities increases with age
Chronic hepatitis B treatment goals
When a patient has been diagnosed with chronic hepatitis B, clinical endpoints of therapy include11,16:
- Achieving sustained suppression of HBV replication
- ALT normalization
- Reducing the risk of liver damage
- HBsAg loss
- Confirmed loss of HBeAg and seroconversion to anti-HBe antibodies (for HBeAg-positive patients) in combination with HBV DNA <2000 IU/mL, which can serve as an intermediate treatment endpoint
ALT=alanine aminotransferase; HBe=hepatitis B e; HBeAg=hepatitis B envelope antigen, HBsAg=hepatitis B surface antigen.
a Hepatocellular carcinoma may occur in patients with chronic hepatitis B without cirrhosis.1
