Evidence-Based Approach to Stopping Oral Antiviral Therapy in Chronic HBV

AbstractPurpose of ReviewTo review the evidence for stopping antiviral therapy with nucleos(t)ide analogues (NA) in patients with chronic hepatitis B.Recent FindingsHBsAg loss is usually stable even without anti-HBs seroconversion after stopping NA therapy. About 50% of HBeAg-positive patients who have achieved anti-HBe seroconversion and have stopped NA therapy remain in virological remission. Consolidation therapy increases the response rate. In HBeAg-negative hepatitis, stable virological remission is documented in 30% after NA discontinuation. Interestingly, some studies document unexpectedly high long-term HBsAg loss rates after stopping therapy.SummaryEvidence supports NA discontinuation, especially after HBsAg seroclearance. In HBeAg-positive patients, NA can be stopped 12 months after anti-HBe seroconversion but severe flares have to be considered. NA discontinuation is also possible in selected HBeAg-negative patients if close monitoring can be guaranteed. The high rate of HBsAg loss needs further evaluation.
