Background/Objectives: Previous studies suggested a link between Helicobacter pylori (H. pylori) infection and steatotic liver disease, now termed metabolic dysfunction-associated steatotic liver disease (MASLD). This study aimed to identify the association of active H. pylori infection and the new concept of MASLD in a longitudinal cohort. Methods: We reviewed 1497 health examinees who had two endoscopic biopsies for H. pylori activity without hepatic steatosis at the baseline abdominal ultrasonography. Subjects were classified into four groups based on H. pylori activity. Multivariable Cox models assessed the link between active H. pylori infection status and incident MASLD. Results: Over a median follow-up of 31.1 months, 247 subjects (16.5%) developed MASLD. The groups were: H. pylori na & iuml;ve (n = 57, 15.6%), de novo (n = 31, 15.3%), eradicated (n = 32, 16.1%), and persistent (n = 127, 17.4%). The H. pylori persistent group had a higher risk of MASLD compared to na & iuml;ve group (hazard ratio: 1.41; 95% confidence interval: 1.01-1.96; p-value = 0.045). The association between H. pylori infection and incident MASLD was significant only with ongoing infection. Conclusions: Persistent H. pylori infection increases the risk of MASLD, indicating that active infection may contribute to MASLD development. Eradicating active H. pylori infection might help lower the incidence of MASLD.
