Between-meal risedronate does not alter bone turnover in nursing home residents
Open accessAbstract
OBJECTIVES: To assess the effect of between‐meal weekly risedronate and daily calcium 630 mg and vitamin D 400 IU on bone turnover markers. DESIGN: Randomized,double‐blind,placebo‐controlled trial. SETTING: Skilled nursing home (NH). PARTICIPANTS: Sixty skilled‐NH residents (46 men, 14 women), mean age±standard deviation of 76±6, were randomized to receive risedronate 30 mg (n=31) or matching placebo (n=29) once weekly for 12 weeks. All received 315 mg calcium with 200 IU vitamin D twice daily. MEASUREMENTS: Bone‐specific alkaline phosphatase (BSAP), N‐telopeptide of type 1 collagen (NTx), 25‐hydroxyvitamin D (25OHD), and parathyroid hormone were measured at baseline and 6 and 12 weeks. RESULTS: Risedronate reduced BSAP significantly more than placebo ( P <.05) at 6 weeks but not at 12 weeks; no treatment effect on serum NTx was observed. Defining hypovitaminosis D as a serum 25OHD concentration below 32 ng/mL, 50 of 53 (94%) study participants were low at baseline (mean 25OHD 19 ng/mL). Vitamin D levels remained insufficient in 74% of participants after 12 weeks. CONCLUSION: In this NH population, weekly risedronate administered using a between‐meal dosing schedule reduced serum BSAP at 6 weeks of treatment; this effect was not observed at 12 weeks. The overall lack of change in bone turnover markers suggests that this risedronate dose and schedule would not be expected to increase bone density or reduce fracture risk in this population. Hypovitaminosis D was common and not reliably corrected by 400 IU of vitamin D daily. Despite an extremely high osteoporotic fracture risk in NH residents, additional study is required to determine under which conditions pharmacological treatment is efficacious in this population and define approaches that assure vitamin D repletion.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
