The effects of inhaled corticosteroids (ICSs) in asthma include reduced severity of symptoms, improved pulmonary function, diminished bronchial hyperresponsiveness (BHR), prevention of exacerbations, and possible prevention of airway wall remodeling. Compared with an inhaled beta(2)-agonist, ICSs improve airway function and BHR, reduce bronchial-epithelium abnormalities, decrease bronchial inflammation, and reduce inflammatory-cell infiltration into the bronchial lamina propria; thus, they may prevent airway remodeling. In children, early use of ICSs may result in improved airway function over time. ICSs reduce use of prednisone, asthma medications, hospitalizations, and urgent-care visits. The primary side effects of ICSs in children are limited to transient reduction in growth. Compared with a leukotriene receptor antagonist (LTRA), ICSs produced a greater change from baseline in FEV(1) and greater reductions in symptoms. A long-acting beta(2)-agonist (LABA) combined with an ICS produced greater improvements than does therapy with ICSs even at higher doses. In COPD, the therapeutic value of ICSs is not as clear. While clinical trials in patients with mild COPD have not shown a reduction in decline in FEV(1) over time, other studies have shown that ICS therapy reduces exacerbations in patients with more severe COPD. Combination therapy with both ICS and LABA has recently been shown to be effective in COPD, where studies have documented additive improvement in FEV(1). Overall, the same therapeutic approaches show clinical effectiveness in both asthma and COPD. This supports the hypothesis that there are some similarities in these obstructive airway diseases. Future approaches should further define phenotypes, perhaps based in part on pharmacogenetic factors that will guide anti-inflammatory therapy in asthma and COPD.
