Inhaled corticosteroids (ICS) are a recommended first-line preventive therapy for asthma. However, some studies have linked long-term use with bone density-related adverse effects, such as osteoporosis and fractures, but most of these studies have included patients with chronic obstructive pulmonary disease who may be more susceptible to these outcomes.
A systematic review, published in BMJ Open (online, 24 November 2015)[1]
, has found no association between ICS use lasting one to four years and these adverse events. Among 18 observational and randomised controlled studies involving only patients with asthma, the researchers found no link between ICS and the risk of fractures in children or adults, nor with bone mineral density loss.
Researchers say the findings should provide reassurance to prescribers, and help them more accurately judge the benefits and harms of ICS treatment for asthma.
