The study titled "Helicobacter pylori-Related Chronic Gastritis as a Risk Factor for Lower Bone Mineral Density" [2025] investigates the association between chronic gastritis caused by Helicobacter pylori (H. pylori) and bone mineral density (BMD) in a population-based cohort. The research involved 1,318 subjects from the Research on Osteoarthritis/Osteoporosis Against Disability (ROAD) cohort, focusing on how different stages of gastritis affect BMD.
The study utilized serological tests to assess H. pylori antibody titers and pepsinogen levels, with BMD measured using dual-energy X-ray absorptiometry (DXA). The analysis revealed that the severity of gastritis significantly impacts BMD, particularly in the femoral neck region.
Below is a Plotly graph illustrating the mean BMD levels in participants with and without H. pylori-related chronic gastritis:
The findings suggest that chronic inflammation due to H. pylori infection may contribute to osteoporosis risk through mechanisms involving pro-inflammatory cytokines that inhibit bone remodeling. The study emphasizes the importance of considering gastritis stage when evaluating osteoporosis risk in H. pylori-infected individuals.
Potential biases include reliance on serological tests for diagnosing H. pylori infection, which may lead to misclassification. The cross-sectional design limits causal inference, and the association with lumbar spine BMD was not significant.
Further research is needed to explore the molecular mechanisms linking H. pylori-induced inflammation to osteoporosis and to evaluate the potential benefits of eradication therapy in preventing bone density loss.
