Insights
Metabolic dysfunction-associated steatotic liver disease (MASLD) aids hepatitis B virus (HBV) DNA clearance in chronic hepatitis B (CHB) patients with normal ALT. MASLD enhances immune cell activity, promoting viral clearance.
Area of Science:
- Hepatology
- Immunology
- Virology
Background:
- Hepatitis B virus (HBV) infection remains a global health concern, especially in patients with normal alanine aminotransferase (ALT) levels.
- Metabolic dysfunction-associated steatotic liver disease (MASLD) is increasingly prevalent in chronic hepatitis B (CHB) patients, complicating management.
- This study examines the impact of MASLD on HBV DNA clearance in CHB patients with normal ALT.
Purpose of the Study:
- To investigate the relationship between MASLD and HBV DNA clearance in CHB patients with normal ALT.
- To explore the immunological mechanisms underlying HBV DNA clearance in the presence of MASLD.
Main Methods:
- Retrospective analysis of 403 CHB patients with normal ALT who received antiviral therapy.
- Diagnosis of MASLD based on liver biopsy findings.
- Single-cell data analysis of relevant datasets (GSE192740, GSE182159).
Main Results:
- CHB patients with MASLD demonstrated a higher likelihood of achieving HBV DNA clearance.
- Increased proportion of CD8+Teff-GZMH cells and enhanced interactions among CD8+ Trm-CD69 cells were observed in the MASLD group.
- Elevated Monocyte-THBS1 proportion and activated CCL-CCR pathways were noted in patients with MASLD.
Conclusions:
- Monocyte-THBS1 cells may activate CD8+ Trm-CD69 T cells, enhancing immune response via the CCL-CCR signaling axis.
- This immune activation facilitates immune cell recruitment and improves hepatitis B virus (HBV) clearance.
- MASLD may play a beneficial role in managing CHB by promoting viral clearance through immune modulation.
Background:
HBV infection continues to pose a significant global health challenge, particularly in patients with normal alanine aminotransferase (ALT) level. The increasing prevalence of Metabolic dysfunction-associated steatotic liver disease (MASLD) among individuals with chronic hepatitis B (CHB) also presents new complications in management. The study aimed to investigate the relationship between MASLD and HBV DNA clearance in CHB patients with normal ALT.
Methods:
403 patients with ALT levels below the normal threshold who underwent liver biopsy at our institution and subsequently received antiviral therapy with NAs were retrospectively examined. Among these, 177 patients were diagnosed with MASLD. Further single cell data analysis was conducted on GSE192740 and GSE182159.
Results:
CHB patients concurrent with MASLD had a higher probability of achieving HBV DNA clearance. The proportion of CD8+Teff-GZMH cells was increased in the MASLD group. The interactions among CD8+ Trm-CD69 cells and other T cell subtypes were enhanced, especially within the active CCL-CCR pathways. An elevated proportion of Monocyte-THBS1 was also observed.
Conclusions:
CD8+ Trm-CD69 T cells may be activated by Monocyte-THBS1 cells, thereby stimulating the immune system via the CCL-CCR signaling axis. This activation facilitates the recruitment of immune cells and enhances the clearance of hepatitis B virus (HBV).
