To determine the strength of association between the dose of inhaled corticosteroids (ICS) and risk of non-vertebral fracture in adults.. A systematic review and meta-analysis of case-control studies of non-vertebral fractures in adults, in which at least two doses of ICS were reported as the dose of beclomethasone dipropionate (BDP) or equivalent.. Five case-control studies were identified, with a total of 43 783 cases and 259 936 controls. There was an association between the risk of non-vertebral fracture and increasing dose of BDP. The random-effects odds ratio of relative risk for a non-vertebral fracture was 1.12 (95% confidence interval 1.00-1.26) per 1000 microg increase in the daily dose of BDP or equivalent.. In older adults, the relative risk of non-vertebral fractures increases by about 12% for each 1000 microg/day increase in the dose of BDP or equivalent. The magnitude of this risk was considerably less than other common risk factors for fracture in the older adult.

Deleterious effect of oral corticosteroids on bone has been well documented, whereas this remains debated for inhaled ones (ICS). Our objectives were to analyze the effects of ICS on bone mineral density, fracture risk and bone markers. We performed an exhaustive systematic research of all controlled trials potentially containing pertinent data, peer-reviewed by a dedicated WHO expert group, and comprehensive meta-analyses of the data. Inclusion criteria were ICS, and BMD/markers/fractures in asthma/chronic obstructive pulmonary diseases (COPD) and healthy patients. Analyses were performed in a conservative fashion using professional dedicated softwares and stratified by outcome, study design and ICS type. Results were expressed as standardized mean difference/effect size (ES), relative risk (RR) or odds ratio (OR), depending on study design and outcome units. Publication bias was investigated. Twenty-three trials were reviewed; 11 papers fit the inclusion criteria and were assessed for the main analysis. Quality scores for the randomized controlled trials (RCTs) were 80%, 71% for the prospective cohort studies, and 78% for the retrospective cohort and cross-sectional studies. We globally assessed ICS effects on BMD and found deleterious effects: ES=0.61 ( p=0.001) for healthy subjects, and ES=0.27 ( p<0.001) for asthma/COPD patients. For these patients, this effect was 0.21 ( p<0.01) at the lumbar spine, and 0.26 ( p<0.001) at the hip or femoral neck. A single study evaluated the impact of ICS on hip fracture and reported an increased OR of 1.6 (1.24; 2.03). Lumbar fracture rate differences did not reach the level of statistical significance: 1.87 (0.5; 6.94). Osteocalcin and PICP were decreased and ICTP, pyridinoline and deoxypyridinoline levels were not significantly affected. Budesonide (BUD) appeared to be the ICS inducing the less deleterious effects on bone, followed by beclomethasone dipropionate (BDP) and triamcinolone (TRI). Publication bias investigation provided non-significant results. In our meta-analyses, BUD at a mean daily dose (SD) of 686 microg (158 microg), BDP at 703 microg (123 microg) and TRI at 1,000 microg (282 microg) were found to affect bone mineral density and markers in patients suffering from the two major respiratory diseases. These findings could have practical implication in the long-term management of asthmatic and COPD patients.

To determine whether children or adolescents who are exposed to inhaled corticosteroids (ie, beclomethasone, budesonide, fluticasone) are at a higher risk of having bone fractures compared with nonexposed individuals.. We performed a population-based nested case-control analysis using data from the United Kingdom-based General Practice Research Database. Within a base population of 273,456 individuals aged 5 to 79 years, we identified by International Classification of Diseases codes children or adolescents who were aged 5 to 17 years with a fracture diagnosis and up to 6 control subjects per case matched to cases on age, gender, general practice attended, calendar time, and years of history in the GPRD. We compared use of inhaled steroids before the index date between fracture cases and control patients.. We identified 3744 cases and 21,757 matched control subjects aged 5 to 17 years. Current exposure to inhaled steroids did not reveal a substantially altered fracture risk compared with nonusers, even in individuals with current longer term exposure (ie, > or =20 prescriptions; adjusted odds ratio 1.15; 95% confidence interval: 0.89-1.48). In individuals with current or previous exposure to oral steroids, the adjusted odds ratio for current long-term inhaled steroid use compared with nonusers was 1.21 (95% confidence interval: 0.99-1.49).. Exposure to inhaled steroids does not materially increase the fracture risk in children or adolescents compared with nonexposed individuals.
