BMD, adjusted for size, should be assessed as the primary outcome in studies of bone health in children with JIA. Quantitative computed tomography could be used where equipment is available as it offers the advantage of measuring volumetric density. Bisphosphonates are a promising treatment for osteoporosis in children with JIA, but the quality of the current evidence is poor. The accurate assessment of outcome is crucial. There are still uncertainties about the use of bisphosphonates in children, including whether the positive effects of treatment continue over time, the length of treatment and the maximal bone mass gain that can be achieved. Adults with JIA may have persistent low BMD compared with an otherwise healthy population together with an increased risk of fracture. There are no studies evaluating the costs of treating children with JIA and low BMD and/or fragility fractures. There are few data evaluating the costs of treating JIA in general. In the first 12 months after diagnosis, children with all JIA disease subtypes consume large, but highly variable, quantities of health service resources, the largest component being the consultant rheumatology appointments. Data from a larger cohort, over a longer period, are required to substantiate these results further. Further research is needed to assess more clearly the role and permit licensing of bisphosphonates for treatment of children, and in particular, longer-term studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
