fluticasone and Fractures--Bone

The effect of inhaled corticosteroids (ICS) on fracture risk in patients with chronic obstructive pulmonary disease (COPD) remains uncertain. The aim of this study was to evaluate the association between ICS and fractures in COPD.. MEDLINE, EMBASE, regulatory documents and company registries were searched up to August 2010. Randomised controlled trials (RCTs) of budesonide or fluticasone versus control treatment for COPD (≥24 weeks duration) and controlled observational studies reporting on fracture risk with ICS exposure vs no exposure in COPD were included. Peto OR meta-analysis was used for fracture risk from RCTs while ORs from observational studies were pooled using the fixed effect inverse variance method. Dose-response analysis was conducted using variance-weighted least squares regression in the observational studies. Heterogeneity was assessed using the I(2) statistic.. Sixteen RCTs (14 fluticasone, 2 budesonide) with 17,513 participants, and seven observational studies (n=69,000 participants) were included in the meta-analysis. ICSs were associated with a significantly increased risk of fractures (Peto OR 1.27; 95% CI 1.01 to 1.58; p=0.04; I(2)=0%) in the RCTs. In the observational studies, ICS exposure was associated with a significantly increased risk of fractures (OR 1.21; 95% CI 1.12 to 1.32; p<0.001; I(2)=37%), with each 500 μg increase in beclomethasone dose equivalents associated with a 9% increased risk of fractures, OR 1.09 (95% CI 1.06 to 1.12; p<0.001).. Among patients with COPD, long-term exposure to fluticasone and budesonide is consistently associated with a modest but statistically significant increased likelihood of fractures.

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.

Osteoporosis is common in patients with COPD, but its prevalence and progression are not well characterized. Concerns have been raised over the possible deleterious effect of long-term therapy with inhaled corticosteroids (ICSs) on bone density in this population. Here, we investigated the long-term effects of therapy with fluticasone propionate (FP) alone, salmeterol (SAL) alone, and a SAL/FP combination (SFC) on bone mineral density (BMD) and bone fractures in patients with moderate-to-severe COPD in the TOwards a Revolution in COPD Health (TORCH) study.. A randomized, double-blind, parallel-group, placebo-controlled study conducted at 88 US centers involving 658 patients (a subset of 6,184 international subjects in TORCH). Therapy with placebo, SAL (50 microg), FP (500 microg), or SFC (SAL 50 microg/FP 500 microg) twice daily was administered for 3 years. Baseline and yearly measurements of BMD at the hip and lumbar spine were performed. The incidence of traumatic and nontraumatic bone fractures was recorded.. At baseline, 18% of men and 30% of women had osteoporosis, and 42% of men and 41% of women had osteopenia based on BMD assessments. Forty-three percent of subjects completed all testing. The changes in BMD at the hip and lumbar spine over 3 years were small. No significant differences were observed between treatment arms (adjusted mean percent change from baseline at hip was -3.1% for placebo, -1.7% for SAL, -2.9% for FP, and -3.2% for SFC therapy, respectively; while, the corresponding changes for the lumbar spine were 0, 1.5%, -0.3%, and -0.3% for placebo, respectively, SAL, FP, and SFC therapy). The incidence of fractures was low and was similar for all treatments (5.1% to 6.3%).. Osteoporosis is highly prevalent in patients with COPD, irrespective of gender. In the TORCH study, no significant effect on BMD was detected for ICS therapy compared with placebo.. ClinicalTrials.gov Identifier: NTC00268216.

There has been inconsistent evidence on the association between use of inhaled corticosteroids (ICS) and increased risk of nonvertebral fractures in patients with asthma or chronic obstructive pulmonary disease (COPD). In a large population-based study in the United Kingdom, we estimated the association between fluticasone propionate/salmeterol fixed-dose combination (FSC) and other ICS use and nonvertebral fracture incidence among patients with COPD.. We identified a cohort of patients aged ≥ 45 years with COPD in the General Practice Research Database (GPRD) between 2003 and 2006. We used a nested case-control design to estimate the odds of incident nonvertebral fractures associated with prior prescriptions of FSC and other ICS, applying conditional logistic regression and controlling for potential confounders. Exposure to FSC and other ICS was assessed by recency, duration, and number of prescriptions. Average daily dose was defined as low, medium, high, or very high using fluticasone propionate equivalents.. We identified 1523 nonvertebral fracture cases among 53 191 patients with COPD at risk in the cohort. Use of FSC in the year prior to the index date was associated with a statistically significant increase in the odds of nonvertebral fractures (odds ratio [OR], 1.25; 95% confidence interval [CI], 1.07-1.47); however, there was no increase in the odds of nonvertebral fractures for other ICS use (OR, 1.12; 95% CI, 0.97-1.30). When examining results by the recent use of prescriptions, an exposure that occurred farther from the index date was associated with a significant increase in nonvertebral fracture (26-52 days prior OR, 1.36; 95% CI, 1.04-1.77; 53-365 days prior OR, 1.39; 95% CI, 1.07-1.78), whereas categories of more recent use (0-12 days prior or 13-25 days prior) were not associated with nonvertebral fractures relative to no FSC use. No pattern of association between increasing levels of FSC or other ICS average daily dose and increased odds of nonvertebral fracture was observed.. We did not observe a consistent association between prescriptions of FSC or other ICS in terms of recent use or average daily dose in the prior year and increases in the odds of nonvertebral fractures in patients with COPD, although ever use of FSC was associated with a slight elevation in the odds.

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.
