Abstract: Current guidelines for the management of chronic obstructive pulmonary disease (COPD) recommend limiting the use of inhaled corticosteroids (ICS) to patients with more severe disease and/or increased exacerbation risk. However, there are discrepancies between guidelines and real-life practice, as ICS are being overprescribed. In light of the increasing concerns about the clinical benefit and long-term risks associated with ICS use, therapy needs to be carefully weighed on a case-by-case basis, including in patients already on ICS. Several studies sought out to determine the effects of withdrawing ICS in patients with COPD. Early studies have deterred clinicians from reducing ICS in patients with COPD as they reported that an abrupt withdrawal of ICS precipitates exacerbations, and results in a deterioration in lung function and symptoms. However, these studies were fraught with numerous methodological limitations. Recently, two randomized controlled trials and a real-life prospective study revealed that ICS can be safely withdrawn in certain patients. Of these, the WISDOM (Withdrawal of Inhaled Steroids During Optimized Bronchodilator Management) trial was the largest and first to examine stepwise withdrawal of ICS in patients with COPD receiving maintenance therapy of long-acting bronchodilators (ie, tiotropium and salmeterol). Even with therapy being in line with the current guidelines, the findings of the WISDOM trial indicate that not all patients benefit from including ICS in their treatment regimen. Indeed, only certain COPD phenotypes seem to benefit from ICS therapy, and validated markers that predict ICS response are urgently warranted in clinical practice. Furthermore, we are now better equipped with a larger armamentarium of novel and more effective long-acting β2-agonist/long-acting muscarinic antagonist combinations that can be considered by clinicians to optimize bronchodilation and allow for safer ICS withdrawal. In addition to providing a review of the aforementioned, this perspective article proposes an algorithm for the stepwise withdrawal of ICS in real-life clinical practice.

While inhaled corticosteroid (ICS)-containing regimens benefit certain patients with chronic obstructive pulmonary disease (COPD), concerns about the inappropriate overuse of ICS in real-life practice, their clinical benefit and long-term risks, and considerable waste of health care resources that could be better used on other more appropriate management strategies prompted studies to evaluate whether certain patients already on ICS therapy fare better without it.1 This perspective paper explores the evidence available on ICS withdrawal in patients with COPD and the potential phenotypes that can be withdrawn from ICS therapy. Furthermore, an algorithm for clinical practice is proposed to address the following critical questions: 1) In which patients is ICS withdrawal safe? and 2) How to withdraw ICS in appropriate patients?
Current guideline recommendations and real-life utilization of ICS in COPD
Although ICS have been long used in the management of COPD, evidence supporting their use has been considered equivocal and their positioning in guidelines as controversial. According to the latest 2015 update of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) report, ICS in combination with a long-acting β2-agonist (LABA) and/or long-acting muscarinic antagonist (LAMA) is the first recommended choice for patients with a high-risk of exacerbations (Groups C and D; Figure 1).2 In addition to this international “gold standard” guideline, a number of national and multinational guidelines exist; however, their recommendations pertaining to the use of ICS are inconsistent with those of the GOLD report, in part, due to the varying criteria for categorizing patients with COPD and different interpretations of the equivocal evidence supporting ICS use.1,3–7 Despite this, there is consensus that ICS are indicated in combination with long-acting bronchodilators (LABDs) for patients with COPD at risk of exacerbations and/or in those with asthma–COPD overlap syndrome (ACOS), but never as monotherapy.

It is not surprising that there is a tremendous amount of confusion surrounding the use of ICS for the management of COPD in clinical practice. Several studies in multiple countries found discrepancies between guideline recommendations and real-life practice regarding ICS use in patients with COPD.8–10 In fact, ICS are being widely prescribed to the majority of patients with COPD, many of whom do not meet the recommendation criteria for ICS use (ie, 38.8% and 51.8% of GOLD Groups A and B, respectively).10 Market research estimates suggest that ICS are used by >70% of patients with COPD, and given as initial therapy to >50% of newly diagnosed patients, mostly in combination with a LABA.11 These high real-world utilization rates are also corroborated by the treatment profiles of patients entering recent randomized controlled trials (RCTs), where ~35% of patients classified into either GOLD Group A or B were receiving ICS at baseline.12,13
Evidence for the use of ICS in COPD: is there a benefit?
The introduction of ICS in the management of COPD was rather unorthodox and unsubstantiated for nearly 20 years (summarized in Table 1 and previously reviewed in detail elsewhere).1,11,14,15 Briefly, in the 1980s, ICS were adopted in COPD on the basis of their effectiveness in asthma rather than scientific evidence.11,16 The earliest RCTs of ICS therapy in mild COPD were conducted in the late 1990s; however, their outcomes were negative.11,15,17,18 ISOLDE (Inhaled Steroids in Obstructive Lung Disease in Europe) was the first trial to demonstrate a beneficial effect of ICS on the occurrence of exacerbations in patients with moderate-to-severe COPD; albeit, no benefit on the rate of lung function decline was observed.19 In 2001, a large population-based cohort study of 22,620 patients with COPD and a very recent hospitalization found that those who received ICS within 90 days postdischarge had 24% fewer rehospitalizations and a 29% risk reduction for mortality during a 1-year follow-up.20 Although these findings are not definitive due to their observational nature, they suggest that patients who have had a hospitalization in the past year should continue receiving ICS. From 2002 onward, the subsequent cohort of RCTs began evaluating ICS in combination with LABDs.11,21,22
In the landmark TORCH (TOwards a Revolution in COPD Health) trial, it was found that ICS plus a LABA (ICS + LABA) resulted in significantly fewer exacerbations, slower rate of decline in lung function, and improved health status; however, there was only a trend toward improved survival.22 These findings formed the initial basis for the inclusion of ICS-containing treatment regimens in clinical guidelines.2,11 At this time, the importance of exacerbations as a key determinant of health status and its association with a faster decline in lung function was being recognized, and the prevention of exacerbations became a key objective of COPD management.16 Of note, a post hoc analysis of the TORCH data, which evaluated the independent contribution of ICS and LABA, found that the benefits of ICS + LABA were actually provided by the LABA.1,15,23 Soon after TORCH, the INSPIRE (Investigating New Standards for Prophylaxis in Reduction of Exacerbations) trial was the first to show that ICS + LABA was no more effective than a LAMA in preventing exacerbations in patients with severe COPD, which initiated the discussion of whether adding ICS to LABDs is beneficial.24 Indeed, a recent Cochrane meta-analysis questioned the superiority of ICS + LABA combinations over LABA alone in preventing exacerbations.25 Lastly, the findings of the SUMMIT (Study to Understand Mortality and MorbidITy in COPD) trial were recently presented at the 2015 European Respiratory Society Congress.26 The SUMMIT trial to evaluate the impact of a once-daily ICS + LABA (fluticasone furoate/vilanterol) versus the monocomponents on the survival of 16,485 patients with moderate COPD and either a history or increased risk of cardiovascular disease (CVD). After a 44-month follow-up, it was found that the risk of mortality on ICS + LABA was 12.2% lower than on placebo over the study period; however, this difference was not statistically significant (P=0.137). While the findings of the TORCH trial suggested that ICS + LABA may reduce mortality in patients with COPD, particularly those with CVD risk, no study to date has been able to demonstrate a benefit.22,26
What are the risks associated with ICS?
A number of local and systemic adverse events have been associated with ICS, particularly with long-term and high-dose use.1,15 The local adverse events include pneumonia,27,28 oropharyngeal candidiasis,29 and tuberculosis,30,31 and the systemic adverse events include cataracts,32,33 glaucoma,15 osteoporosis and bone fractures,34 easy bruising,18 type 2 diabetes,35 and even cases of adrenal suppression.36 While there have always been concerns about the risks of developing osteoporosis, cataracts, and diabetes in patients with COPD, risk of pneumonia is arguably the most notable and well-established adverse event associated with ICS use in COPD, as supported by consistent evidence from RCTs.1,14,15,24,27,37 Corroborating this, a recent Canadian population-based cohort study of 103,386 patients with COPD who were treated with ICS demonstrated that discontinuation of ICS was associated with a 37% reduction in the risk of serious pneumonia.38 Indeed, in the latest update of the GOLD report, it is cautioned that long-term ICS-containing treatment should not be prescribed outside their indication due to risk of pneumonia and the possibility of a slight increased risk of fractures following long-term exposure.2 As patients with COPD are more likely to be older and often have several comorbidities for which they receive multiple medications, they are more susceptible to ICS-associated adverse events, and their potential risks need to be weighed against the likely benefits on a case-by-case basis, even in those already on ICS.1 Given the concerns about the risk–benefit profile of ICS, there has been a renewed interest in reevaluating the role of ICS in COPD and identifying which patients can be managed as well with alternate therapies.37
Evidence regarding ICS withdrawal
Early observational studies and RCTs investigating the implications of ICS withdrawal in patients with COPD found that an abrupt cessation of ICS therapy precipitates exacerbations, and results in a deterioration in lung function, symptoms, and health status (summarized in Table 2).39–44 However, a meta-analysis of three of these RCTs (ie, COPE, COSMIC [COPD and Seretide: a Multi-center Intervention and Characterization], and WISP), the only trials deemed to be acceptable in terms of quality and level of bias, determined that withdrawal of ICS was not associated with any statistically significant increase in the exacerbation rate, and that the effects on other outcomes, such as lung function and health status, were inconclusive.45 The contradictory findings of these studies may be due to a number of methodological issues, including heterogeneity in patients’ characteristics, disease severity, outcome definitions (eg, exacerbations), concomitant treatments (eg, run-in period treatment, maintenance with LABDs vs placebo), and setting (ie, primary vs secondary care).45,46 Of note, since patient inclusion in all trials was based on spirometry while receiving ICS therapy, this does not rule out a diagnosis of concomitant asthma, even if spirometry was of no significant reversibility.42–44 Additionally, in COSMIC, the forced expiratory volume in 1 second (FEV1)/forced vital capacity ratios used do not match the diagnostic criteria for COPD (ie, <70%), suggesting that these patients may have had an asthma component, and thereby, cessation of ICS could have been detrimental.2,43
According to the latest GOLD recommendations, patients with COPD and a low risk of exacerbations should not be prescribed ICS-containing regimens.2 Given that a large proportion of patients are already initiated on such regimens, it would be helpful to know if there are consequences associated with ICS withdrawal in such populations (ie, GOLD Groups A and B). Recently, in the first real-life prospective study (OPTIMO [Real-Life study On the aPpropriaTeness of treatment in MOderate COPD patients]), it was demonstrated that withdrawal of ICS in patients with symptomatic, moderate COPD (ie, FEV1 >50% predicted) at a low risk of exacerbations (ie, <2/year) was not associated with any deterioration in lung function, symptoms, and exacerbation rate over a 6-month observation period.47 These findings were further confirmed by the recent INSTEAD (Indacaterol: Switching Non-exacerbating Patients with Moderate COPD from Salmeterol/Fluticasone to Indacaterol) trial, the first RCT with a clearly defined patient population with moderate COPD (ie, FEV1 50%–80% predicted) and no prior exacerbation history, which found that switching from a fixed-dose combination of ICS + LABA to a LABA was not associated with any differences in lung function, symptoms, health status, and exacerbations.48 In addition to supporting the current GOLD recommendations (ie, no need for ICS in Groups A and B), the results from both studies suggest that ICS therapy can be safely withdrawn from patients with moderate COPD and a low risk of exacerbations provided that they are left on maintenance treatment with LABDs.
In all studies to date, withdrawal of ICS has been abrupt. It is well known that an abrupt cessation of chronic corticosteroid therapy precipitates rebound systemic effects due to steroid withdrawal symptoms.11,46 Currently, there is no clear evidence on whether abrupt ICS withdrawal is safe; however, similar to the approach used to down-titrate ICS in patients with asthma, a stepwise withdrawal of ICS may minimize the potential risk of rebound steroid effects.11,46,49
Adding to the growing clinical evidence-base on the impact of ICS withdrawal against a background of LABDs, the WISDOM (Withdrawal of Inhaled Steroids During Optimized Bronchodilator Management) trial, which is larger than all of the previous ICS withdrawal RCTs combined, was the first to assess the question of whether a stepwise withdrawal of ICS on top of maintenance therapy with dual bronchodilation (tiotropium/salmeterol) had a similar risk of exacerbations in patients with COPD and a history of exacerbations (ie, GOLD Groups C and D, in whom GOLD recommendations support the addition of ICS to LABD therapy).2,46,50 In this, 12-month, randomized, double-blind, parallel-group, active-controlled trial, 2,485 patients with COPD and a history of exacerbations received triple therapy (ie, fluticasone propionate/tiotropium/salmeterol) during a 6-week run-in period. Afterward, patients were randomized to either continue or withdraw ICS therapy. In the ICS withdrawal group, the dose of ICS was gradually reduced by approximately half in a stepwise fashion every 6 weeks, such that after 12 weeks, ICS was completely withdrawn. It was found that there was no difference in the occurrence of moderate or severe exacerbations between the two groups.50 Additionally, subgroup analyses revealed no notable differences in the occurrence of exacerbations based on age, sex, smoking status, body mass index, ICS or β-blocker therapy at screening, chronic bronchitis, GOLD stage and group, and prior therapy with antibiotics or systemic glucocorticoids. While there was a small, but significant, reduction in lung function when ICS was completely withdrawn, the clinical importance of this is unclear. Taken together, these findings suggest that even patients with severe COPD and a high-risk of exacerbations can be safely withdrawn from ICS therapy as long as they are clinically stable and maintained on a background of LABDs. Even with ICS use being in line with the GOLD recommendations, the WISDOM results also indicate that not all patients with severe-to-very-severe COPD seem to benefit from including ICS in their treatment regimen.
With the intent of identifying potential markers of ICS responsiveness, a substudy on ~500 patients was also performed in the WISDOM trial.46 These patients were evaluated for emphysema, bronchiectasis, diffusing capacity for carbon monoxide, and the following biomarkers: adiponectin, leptin, C-reactive protein, interleukin-6, interleukin-8, tumor necrosis factor-α, fibrinogen, soluble interleukin adhesion molecule-1, serum amyloid A, procalcitonin, and B-type natriuretic peptide. Airway inflammation through differential cell count in sputum and fraction of exhaled nitric oxide (FeNO) was also assessed. Unfortunately, no subgroups or biomarkers were found to be associated with an increased likelihood of exacerbations after ICS withdrawal;46,51 albeit, certain phenotypes and potential biomarkers that have been previously shown to be associated with ICS responsiveness were not evaluated (discussed in the next section).16
COPD phenotypes: which patients benefit from ICS?
Because COPD is a complex and heterogeneous disease with several different pathophysiological mechanisms, it is likely that ICS may have an effect on some components of the disease, particularly when airway inflammation is present.11,15 Increasing evidence suggests that patients with certain COPD phenotypes appear to benefit from ICS treatment, including patients with ACOS, frequent exacerbators, and those with eosinophilia.1,6,15,52
ACOS was only formally recognized by the Global Initiative for Asthma (GINA) and GOLD for the first time in 2014. It has been estimated that ACOS occurs in up to 25% of patients with COPD; however, establishing its prevalence has been difficult because there is no universally accepted definition for this syndrome.1,52–56 According to the GINA/GOLD Consensus Statement, ACOS is characterized by persistent airflow limitation and identified by the features that it shares with both asthma and COPD.56 In addition to having a history or clinical features of asthma, the presence of a large bronchodilator response (ie, >12% and 400 mL) and eosinophilic inflammation may also point to ACOS in patients with persistent airway obstruction.15,56 Due to the presence of an asthma component, patients with ACOS are likely to benefit from ICS therapy. Recently, a large observational study reported a survival benefit in patients with COPD starting on ICS + LABA compared with LABA alone; however, this survival benefit was only observed in those who had a codiagnosis of asthma.57
Frequent exacerbators account for approximately one-third of patients with COPD.52,58 The definition of an exacerbator is based on expert opinion rather than rigorous phenotypic assessment, with a history of exacerbations being the best predictor of exacerbations across all GOLD stages.2 In the current GOLD report, exacerbation risk is based on either GOLD classification of airway limitation or history of exacerbations (ie, high exacerbation risk is defined as ≥2 exacerbations per year or ≥1 hospitalization); however, not all patients with moderate-to-severe COPD (ie, GOLD Groups C and D) are necessarily exacerbators, and therefore, require ICS.2,59 Indeed, in a 26-week, randomized, double-blind, parallel-group trial of patients with moderate-to-severe COPD and no history of exacerbations, it was found that dual bronchodilation (ie, LABA + LAMA) provided significantly better and clinically relevant improvements in lung function versus ICS + LABA.12 The findings from the ENERGITO trial, which were recently reported at the 2015 European Respiratory Society Congress, further corroborate this point.60 In this randomized, double-blind, double-dummy, four-period crossover trial, lung function was evaluated in patients with moderate-to-severe COPD after treatment with LABA + LAMA (ie, tiotropium/olodaterol) versus ICS + LABA (ie, fluticasone propionate/salmeterol). After 6 weeks of treatment, it was found that LABA + LAMA significantly improved lung function compared with ICS + LABA. Thus, subclassification within GOLD Groups C and D may be warranted to take into account nonexacerbators. To complicate matters further, while both history of exacerbations and COPD severity are risk factors for repeat exacerbations, there are a number of other risk factors associated with repeat exacerbations that should be considered, including eosinophilic inflammation, comorbidities and extrapulmonary manifestations (eg, CVD, anxiety, depression, myopathy, reflux disease), chronic bronchitis, and increasing age.6
Lastly, it has been suggested that up to 30% of patients with COPD have eosinophilia.16,61 Eosinophilia has been suggested to be predictive of exacerbations in patients with mild-to-moderate COPD following withdrawal of ICS,62 and both sputum and blood eosinophil levels have been shown to be promising biomarkers of ICS responsiveness in patients with COPD.63,64 In one RCT, a management strategy for patients with COPD that suppressed sputum eosinophil levels ≤3% was found to reduce severe exacerbations.64 Although it has been suggested that sputum eosinophil levels may be the most reliable predictor of ICS responsiveness in patients with COPD to date, obtaining sputum samples is technically demanding and not feasible in routine clinical practice.15 Since there is a reasonable correlation between sputum and blood levels, blood eosinophil levels may offer a more practical alternative.63 Consequently, blood eosinophil levels are currently a topical issue and defining the appropriate cutoff for determining ICS responsiveness in patients with COPD is a subject of intense discussion. In a recent post hoc analysis of two replicate, 12-month, double-blind RCTs comparing a LABA with ICS + LABA in a total of 3,177 patients with moderate-to-severe COPD and a history of ≥1 exacerbation, it was found that across all doses of ICS, ICS + LABA significantly reduced exacerbations by 29% versus LABA alone in patients with blood eosinophil levels of ≥2%.63 Conversely, in another post hoc analysis of two replicate, 26-week, double-blind, double-dummy, parallel-group RCTs, an absolute blood eosinophil cutoff of >300 cells/mm3 at baseline as opposed to a percent cutoff appeared to best differentiate patients with moderate-to-severe COPD who benefited from ICS + LABA versus LABA + LAMA therapy in terms of reduction in exacerbation risk.65 This observation was corroborated by another post hoc analysis of the randomized, double-blind, parallel-group FORWARD (FOsteR 48-week trial to reduce exAceRbations in COPD) trial, which concluded that a greater reduction in exacerbations was observed when ICS was added to a LABA in patients with severe COPD and a history of exacerbations who had an eosinophil count ≥279.8 cells/mm3.66 Using an absolute as opposed to a percent cutoff was further supported by the findings of the Copenhagen General Population Study, which evaluated 7,225 patients with COPD over a median follow-up of 3.3 years and found that an absolute blood eosinophil count of ≥340 cells/mm3 was a better predictor of both moderate and severe exacerbation risk than a percent cutoff of 2%.67 Accordingly, ≥300 cells/mm3 can be tentatively used as a cutoff until this value is further validated in prospective trials. Meanwhile, it will suffice to recognize that blood eosinophil counts can be easily measured in clinical practice as they are more accessible than sputum eosinophil levels.
In addition to eosinophil levels, it has been suggested that FeNO levels can be used as a surrogate marker of eosinophilic inflammation in patients with COPD exacerbations.68,69 A recent review on ACOS suggested the following FeNO levels for comparing between patients with asthma, ACOS, and COPD: >50, 25–50, and <25 ppb, respectively.55 These cutoffs are in line with the 2011 American Thoracic Society FeNO guidelines, which suggest that FeNO <25 ppb provides a strong indication for an unlikely ICS response and FeNO >50 ppb provides a strong indication for a likely ICS response, but FeNO between 25 and 50 ppb should be interpreted with caution.70,71
Safely withdrawing ICS from patients with COPD: a proposed algorithm for clinical practice
Since there is an overall paucity of evidence about when and how ICS can be safely withdrawn, the criteria for continuing or withdrawing ICS in patients with COPD are uncertain and more studies are warranted to characterize patients in whom withdrawal is safe. In a recent Spanish consensus document on the appropriate use of ICS in COPD, a panel of 25 experts voted on statements developed by a coordinator group that systematically reviewed scientific evidence on the efficacy and safety of ICS, and criteria for ICS withdrawal.52 Consensus was reached on the following statements concerning ICS withdrawal: withdrawal of ICS in COPD is feasible, patients who discontinue ICS should be evaluated in the short-term, and ICS withdrawal should be tapered. ICS withdrawal was thought to be possible if there is no evidence of ACOS, no exacerbations in the previous 2 years, and, with a lower level of agreement, in the absence of a positive bronchodilator test and decline after switching from high to low ICS doses. However, it should be kept in mind that these criteria are based on expert opinion and need to be validated in RCTs. Of note, there were also a significant number of statements for which it was difficult to reach a consensus, thereby identifying several areas of uncertainty.
Currently, no national or international clinical guidelines advocate withdrawal of ICS nor do they provide recommendations regarding the safe withdrawal of ICS in patients with COPD. For reasons previously described, there is an urgent need for a step-by-step algorithm that can be applied in real-life clinical practice. Figure 2 proposes such an algorithm and attempts to address the following questions: 1) In which patients is ICS withdrawal safe? and 2) How to withdraw ICS in appropriate patients? This algorithm takes into account not only exacerbation risk, as per GOLD, but also the emerging, neglected ACOS phenotype, as per the GINA/GOLD Consensus Statement. Potential markers of eosinophilia are also considered and noted as optional, as these are still theoretical and need to be tested in RCTs. Furthermore, the stepwise ICS withdrawal protocol on top of maintenance therapy with dual bronchodilation is primarily based on the WISDOM trial, although, instead of down-titrating ICS every 6 weeks, it is proposed that physicians consider stepping down ICS dose every 6–12 weeks. The rationale for this is to ensure that the effects of ICS in the inflammation cascade of COPD have been optimized on a physiological level,72 and from a practical perspective, permit enough time to monitor for potential exacerbations. In regards to optimizing bronchodilation following ICS withdrawal, we are now more equipped than ever before with a larger armamentarium of novel LABA + LAMA combinations that clinicians can consider for more effective bronchodilation maintenance (Table 3).
Table 3 LABA + LAMA combinations currently available or in development
Lastly, it is fully acknowledged that the proposed algorithm will need to be validated, particularly in the real-life setting. Additionally, there are a number of potential barriers to using the proposed algorithm that need to be considered. Health care resources, such as physician time, access to spirometry, and measurement of eosinophil and FeNO levels, may be limited or unavailable; certain countries may not have multiple doses of ICS approved to allow for a stepwise reduction; and patients and physicians may be reluctant to change therapy if it is sufficient in terms of current disease control as opposed to avoiding future risks, such as side effects. Patients may also be resistant to changing therapy, as it will require more effort on their part and there is a potential risk of symptom worsening, especially if they end up having a phenotype that should be receiving ICS therapy.
It is now becoming evident that maintaining or initiating certain patients with COPD on ICS therapy solely on the basis of reducing their risk of exacerbations may not be necessary, particularly if they are maintained on effective dual bronchodilation with a LABA and LAMA. Clinicians need to carefully tailor therapy on a case-by-case basis, and determine who is an appropriate patient for ICS therapy, and if a patient is already on ICS therapy, how to carefully step down ICS therapy without doing harm. Currently, no clinical guidelines provide any recommendations regarding the safe withdrawal of ICS in patients with COPD. Accordingly, until this need is met, this perspective article proposes an algorithm for the stepwise withdrawal of ICS in real-life clinical practice based on the evidence available to date.
