Real-life use of inhaled corticosteroids in COPD patients versus the GOLD proposals: a paradigm shift in GOLD 2011?

Abstract

To the Editor: Clinical trials in chronic obstructive pulmonary disease (COPD) patients have shown that the long-term use of inhaled corticosteroids (ICS) in COPD patients reduced the number of exacerbations per patient per year and improved health status [1]. Early studies have suggested increased ICS efficacy in patients with low lung function and frequent exacerbations [2]. The efficacy was reinforced when ICS was used in conjunction with long-acting β2-agonists (LABA) [3]. In most countries, health authorities approved ICS/LABA combinations in COPD patients with severe airflow impairment and frequent exacerbations, as also recommended in the Global Initiative for Obstructive Lung Disease (GOLD) 2007 document [4]. However, several surveys found poor adherence to this proposal among primary care physicians and pulmonologists in “real life”, ICS being often prescribed at a milder stage of the disease. The GOLD 2011 document proposed a new multidimensional system for the assessment and management of patients with COPD [5]. This system classifies COPD patients into four categories (A, B, C and D) based on the level of symptoms (dyspnoea or global clinical impact) and the risk of future exacerbations, as assessed using the severity of airflow limitation and the past history …
