Evidence for the treatment of osteoporosis with vitamin D in residential care and in the community dwelling elderly
Abstract
INTRODUCTION: Vitamin D is common treatment for osteoporosis. Both age >70 years and living in residential care are associated with increased fracture risk. Community dwelling elderly are a heterogeneous group who may have more similatiry with residential care groups than younger community dwelling counterparts.
AIMS: To review the evidence for cholecalciferol or ergocalciferol tretment of osteoporosis in either community dwelling patients aged ≥70 years of age, or redidential care patients. Secondly endpoints were changes in bone mineral denisty, and in bone turnover markers.
METHODS: We performed a literature search using search terms for osteoporosis and vitamin D. Treatment for at least one year was required.
RESULTS: Only one residential care study using cholecalciferol, showed non-vertebral and hip fracture reduction in vitamin D deficient subjects. In the community setting one quasi randomised study using ergocalciferol showed reduction in total but not hip or non-vertebral fracture, and a second randomised study showed increased hip fracture risk. Three studies reported increases in hip bone mineral denisty.
DISCUSSION: A minority of studies demonstrated a fracture benefit form vitamin D and one suggested possible harm in a community setting. Current practice should be to only offer this treatment to subjects identified as deficient.
