Amelioration of osteopenia and hypovitaminosis D by 1alpha -hydroxyvitamin D3 in elderly patients with Parkinson's disease
Open accessAbstract
OBJECTIVES: A high prevalence of hip and other fractures in elderly patients with Parkinson's disease has been linked to reduced bone mass arising from a defect of renal synthesis of 1, 25-dihydroxyvitamin D (1, 25-[OH]2D). Treatment with 1alpha-hydroxyvitamin D3 (1alpha(OH)D3; an active form of vitamin D) was evaluated for maintaining bone mass and reducing the incidence of hip and other nonvertebral fractures in patients with Parkinson's disease. METHODS: In a double blind, randomised trial, 86 elderly patients with Parkinson's disease (mean Hoehn and Yahr stage, 3; mean age 70.6 years) were randomised to receive either 1 microg 1alpha(OH)D3 daily (treatment group, n=43) or a placebo (n=43) for 18 months. Bone mineral densities in the second metacarpals were determined by computed radiographic densitometry. Serum bone turnover indices were measured serially, and incidence of nonvertebral fractures was recorded. RESULTS: Bone mineral densities decreased 1.2% in the treatment group compared with 6.7% in the placebo group during 18 months (p<0.0001). At baseline in both groups, the serum concentration of 1, 25-[OH]2D was reduced. Parathyroid hormone was abnormally increased in 15 patients (17%) and correlated negatively with serum 25-hydroxyvitamin D, indicating compensatory hyperparathyroidism. Eight patients sustained fractures (six at the hip and two at other sites) in the placebo group, and one hip fracture occurred among treated patients (odds ratio 9.8; p=0.0028). CONCLUSION: By increasing serum 1, 25-[OH]2D concentrations, treatment with 1alpha(OH)D3 can reduce the risk of hip and other non-vertebral fractures in osteoporotic elderly patients with Parkinson's disease by slowing the loss of bone mineral densities.

In the citing paper
“A guideline from AHRQ57 excluded one trial report8 from its review of interventions to prevent falls in older people. The reason for exclusion was that the report did not focus on the outcome of interest, that is, the rate of falls or number of fallers, despite what appeared to be relevant falls data in the affected trial report.”

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.
