Introduction: The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) is increasing among the chronic hepatitis B (CHB) population. This study aimed to explore the impact of metabolic dysfunction (MD) on cirrhosis and cirrhotic complication risks in CHB.
Methods: Patients with CHB were consecutively recruited between 2006 and 2021. The presence of MD was based on the 5 cardiometabolic criteria specified in the MASLD definition. Patients were categorized into MD/non-MD groups based on these criteria.
Results: Eleven thousand five hundred two treatment-naive noncirrhotic patients with CHB were included with a median follow-up of 5.3 years. Patients in the MD group (n = 7,314) were older and had lower hepatitis B virus DNA levels than non-MD patients (n = 4,188). After adjustment for clinical and viral factors, MD patients had significantly higher risks of cirrhosis (adjusted hazard ratio [aHR]: 1.82, 95% confidence interval [CI]: 1.40-2.37, P < 0.001) and cirrhotic complications (aHR: 1.30 per MD, 95% CI: 1.03-1.63, P = 0.025) in a dose-dependent manner. Furthermore, new-onset diabetes mellitus during the follow-up aggravated the risk of cirrhotic complications (aHR: 2.87, 95% CI: 1.34-6.11, P = 0.006). Hepatic steatosis was associated with lower risks of cirrhosis (aHR: 0.57 within 5 years, 95% CI: 0.44-0.74, P < 0.001) and cirrhotic complications (aHR: 0.45, 95% CI 0.23-0.88, P = 0.020). Among individuals with hepatic steatosis, patients with MASLD exhibited a higher cirrhosis risk than non-MD patients.
Discussion: Concurrent and new-onset MDs increase the risks of cirrhosis and cirrhotic complications in patients with CHB, independent of hepatic steatosis. Proactively investigating metabolic comorbidities in CHB is critical to stratify the risk of liver disease progression.
