Abstract
Context: Proton pump inhibitor (PPI) increases the risk of decrease in bone mineral density (BMD). However, whether calcitrol improves this situation is unknown.Objective: The current study investigates the effects of calcitriol on BMD in patients with esomeprazole therapy.Materials and methods: Three hundred and eighty-six participants with gastrointestinal ulcerations were enrolled and randomly assigned into controlled and supplemented groups. Participants in the controlled group were prescribed esomeprazole (20 mg/qd), while the supplemented group was prescribed esomeprazole (20 mg/qd) and calcitriol (2.5 μg/qd). BMD, serum levels of calcium, carboxy-terminal collagen crosslinks (CTX), and alkaline-phosphatase (ALP) were assessed.Results: (1) No significant between-group difference of age, gender, smoking, previous glucocorticoid use and hemoglobin level was found; (2) after 10.6 ± 0.8 d of PPI therapy, BMD T score in the controlled group was slightly increased compared with initial (−1.25 ± 0.08 versus −1.28 ± 0.06, p = 0.084), while there was no change in the supplemented group (−1.25 ± 0.05 versus −1.26 ± 0.03, p = 0.308); (3) during study termination, calcium level in the supplemented group was slightly higher than the controlled group (2.05 ± 0.03 mmol/L versus 2.01 ± 0.05 mmol/L, p = 0.073), while no significant differences of CTX (366.57 ± 43.71 pg/mL versus 373.15 ± 50.23 pg/mL, p = 0.036) and ALP were found among these two groups (50.47 ± 9.32 U/L versus 52.23 ± 10.45 U/L, p = 0.075).Conclusion: Patients with gastrointestinal ulcerations with esomeprazole therapy, calcitriol supplement showed no efficacy on BMD changes.
