Clinical Scorecard: Monitoring B cell Immune Responses Following Discontinuation of Treatment in Hepatitis B Infection
At a Glance
Category Detail
Condition Chronic Hepatitis B (CHB)
Key Mechanisms B cell immunity and memory B cell (MBC) function following nucleos(t)ide analogue (NA) therapy discontinuation.
Target Population Patients with HBeAg-negative chronic hepatitis B who have achieved complete virological control under NA therapy.
Care Setting Clinical research setting involving prospective study design.
Key Highlights
Prolonged NA therapy equalizes frequencies of HBc and HBs-specific MBC. PD-1 expression of HBs-MBC decreases only after treatment withdrawal. Higher activated MBC and plasmablasts observed in patients achieving HBsAg loss. Class-switched HBc-MBC increases temporally with withdrawal flares. Need for larger studies to explore B cell biomarkers for predicting NA withdrawal outcomes.
Guideline-Based Recommendations
Diagnosis
Assess serum quantitative hepatitis B surface antigen (qHBsAg) levels at the time of NA discontinuation.
Management
Consider NA withdrawal in HBeAg-negative CHB patients with low qHBsAg levels.
Monitoring & Follow-up
Monitor for life-threatening ALT flares and viral rebound post-NA withdrawal.
Risks
Risk of life-threatening ALT flares and viral rebound upon discontinuation of NA therapy.
Patient & Prescribing Data
21 patients with HBeAg-negative CHB under prolonged NA therapy.
Functional cure rates of up to 20% observed following NA withdrawal.
Clinical Best Practices
Utilize biomarkers to predict responders to NA therapy discontinuation. Monitor immune responses post-NA withdrawal to guide therapeutic decisions.
