Is Helicobacter pylori infection associated with osteoporosis? a systematic review and meta-analysis.

ABSTRACT

INTRODUCTION: This study used systematic review and meta-analysis to evaluate the association between Helicobacter pylori infection and osteoporosis. MATERIALS AND METHODS: PubMed, Ovid and Web of Science were searched to include observational studies published in English comparing bone mineral density changes between Helicobacter pylori-positive and -negative participants. The quality of the included literature was assessed using the Newcastle-Ottawa Quality Assessment Scale (NOS). R software was used for meta-analysis, and odds ratio (OR) and 95% confidence interval (CI) were calculated to evaluate the relationship between Helicobacter pylori infection and osteoporosis. RESULTS: Twenty-two studies involving 24,176 participants were included in the study. Our meta-analysis showed that Helicobacter pylori infection was significantly associated with the risk of osteoporosis (OR 1.12, 95%CI 1.03, 1.22). Participants infected with the CagA-positive Helicobacter pylori strain were more likely to develop osteoporosis (OR = 1.42, 95%CI 1.09; 1.85). CONCLUSION: Infection with Helicobacter pylori, particularly the CagA-positive strain, has been associated with an increased risk of osteoporosis. The bone health of Helicobacter pylori-positive patients deserves more attention.
