Regular Proton-Pump Inhibitor Intake is Associated with Deterioration of Peripheral Bone Mineral Density, Microarchitecture, and Strength in Older Patients as Assessed by High-Resolution Peripheral Quantitative Computed Tomography (HR-pQCT).

ABSTRACT: Proton-pump inhibitors (PPI) are widely used among older adults and PPI intake has been associated with increased fracture risk. However, their association with bone microarchitecture and strength remains unclear as prior clinical PPI studies were restricted to lower-resolution bone imaging techniques such as DXA. Using high-resolution peripheral computed tomography (HR-pQCT), we prospectively investigated whether long-term PPI use was associated with changes in volumetric bone mineral densities, bone microarchitecture, and strength in older patients. 189 patients aged ≥ 60 years (n = 24 persistent PPI users [p-PPI user], and n = 165 non-PPI users), enrolled as part of a 2-year vitamin D RCT, underwent HR-pQCT scanning of the tibia and radius at 0 and 2 years.
