Nucleoside (Acid) Analogues Treatment in Patients With Normal ALT and Positive HBVDNA.

Hepatitis b virus infection has always been a global public health problem that endangers national health. Current clinical guidelines do not recommend antiviral therapy for people with positive hepatitis b-DNA and normal Alanine Aminotransferase, but studies have found that viral replication is associated with an increased risk of cirrhosis and liver tumors. Nucleoside (acid) analogues can effectively inhibit viral reverse transcriptase, reduce HBV viral load in the blood, thereby reducing secondary inflammation, and contribute to liver cell regeneration and disease recovery. And its side effect is small, adverse reaction rate is low, use safety.
