Abstract
INTRODUCTION: Trabecular bone score (TBS) provides indirect indices of trabecular microarchitecture and bone quality. Several studies have evaluated the influence of proton pump inhibitors (PPIs) on bone mass and geometric parameters, but no studies have evaluated the influence of PPIs on TBS. METHODS: We reviewed the medical records of 1505 women aged 40-89 yr who had bone mineral density (BMD) examinations as a part of the medical diagnosis and disease prevention program and who did not have osteoporotic fractures or conditions that could affect bone metabolism. Among these, we identified 223 women with exposure to PPIs and selected the same number of age- and body mass index (BMI)-matched control patients. We compared TBS and BMD between the PPI exposure group and the control group and performed multivariate regression analyses to determine whether TBS and BMDs are associated with age, BMI, and PPIs exposure. We also examined whether TBS and BMDs are associated with PPIs exposure timing (current, recent, and past). RESULTS: TBS and BMDs were significantly lower in the PPI exposure group than in the control group. In a multivariable linear regression analysis, TBS was significantly associated with age (p < 0.001) and PPI exposure (p = 0.02). In addition, all BMDs were found to be significantly associated with age, BMI, and PPI exposure. Lower TBS was associated with current PPIs use (p = 0.005), but not with recent or past PPIs usage. However, the influence of PPI exposure timing on the BMDs was not consistent between BMD measurement sites. CONCLUSIONS: This study found that TBS is lower in subjects with PPIs exposure than in controls. The association of lower TBS with current PPIs use suggests that trabecular bone quality could be affected early by PPIs, and but the effect might be reversible.
