ABSTRACT
Objective To investigate liver inflammation and fibrosis in patients with chronic HBV infection with a low viral load. Methods Among the HBsAg-positive patients who attended Ganzhou Fifth People's Hospital from April 2019 to June 2022, 41 patients with 20 IU/mL 200-2 000 IU/mL and 4 (26.67%) had an HBV DNA level of 20-200 IU/mL; the patients with G2 liver inflammation accounted for 73.33% (11/15), and those with S2 liver fibrosis accounted for 46.67% (7/15); the patients with ALT ≤30 U/L accounted for 46.67% (7/15); the patients aged ≥30 years accounted for 86.66% (13/15); the patients with LSM > 17 kPa accounted for 6.67% (1/15), those with an LSM value of 12.4-17 kPa accounted for 46.67% (7/15), and those with an LSM value of 9.4-12.4 kPa accounted for 33.33% (5/15). Conclusion Patients with chronic HBV infection and low-level viremia have a relatively high risk of progression of inflammation and fibrosis. ALT level cannot be used as a basis for antiviral therapy in HBV-infected people with a low viral load. LSM based on transient elastography can be used as a noninvasive test to screen for CHB patients with a low viral load, and antiviral therapy should be considered when HBV-infected patients with a low viral load have an age of > 30 years and an LSM value of > 9.4 kPa persistently.
