In fact, Hurst et alshowed that, in ECLIPSE, a significant number of individual patients switch from suffering frequent exacerbations (≥2/year) to 1 or less (and vice versa).8 Further, the extent to which the reduction of exacerbation rates observed in clinical trials can be directly extrapolated to the real world, where compliance with treatment is likely lower, is unclear. A COPD exacerbation can interfere with your life, potentially involving a hospital stay. 2001;164(3):358-364. doi: http://dx.doi.org/10.1164/ajrccm.164.3.2010017, 11.

Additionally, disease flare-ups often contribute to a more rapid progression of lung function decline1 that is characteristic of COPD. Following an exacerbation, appropriate measures for preventing a future event should be initiated. In any case, recurrent hospitalization for exacerbations is a common and serious problem in COPD 59,60 and reducing the risk for exacerbation-associated rehospitalization is thus an important treatment goal. Was it because they were poor perceivers, as discussed above, or just had no prior severe episodes? Respir Res. Group 2 (n=125, 37%) was labeled as moderate respiratory COPD because they showed milder airflow limitation (mean FEV1 63% predicted), but had similar emphysema characteristics compared to Group 1. However, consideration of any review comments remained at the full discretion of the authors.

Reduction of exacerbations by the PDE4 inhibitor roflumilast--the importance of defining different subsets of patients with COPD. D'Urzo A, Ferguson GT, van Noord JA, et al. In vitro, ICS has limited efficacy in suppressing inflammation in cells harvested from COPD patients, an effect that seems to be related to a marked reduction in histone deacetylase-2, the nuclear enzyme required by corticosteroids to de-activate inflammatory genes.86-88 In addition, high doses of ICS may have deleterious effects on bone metabolism and also appear to increase the risk of pneumonia in COPD. Prediction of risk of COPD exacerbations by the BODE index. for us to be able to institute those medications. In summary, this book on the Evidence-based Management of Patients with Respiratory Failure provides important information to improve patient outcome by clearly identifying the research evidence that we can apply in daily clinical practice. 5. Chronic obstructive pulmonary disease (COPD) is characterized by chronic respiratory symptoms such as cough, phlegm production and dyspnea that have a great impact on the patient due to physical limitation and reduction of the quality of life [].In addition, patients with COPD may experience episodes of exacerbation, characterized by worsening of symptoms in relation to their .

Chronic obstructive pulmonary disease patients with psychiatric disorders are at greater risk of exacerbations. These diseases erode the health and well-being of the patients and have a negative impact on families and societies. For instance, results from 1 study showed that in patients with both obstructive sleep apnea (OSA) and COPD (termed an overlap syndrome), treatment with continuous positive airway pressure (a standard therapy for OSA) decreased the risk for exacerbations requiring hospitalization.129 Much more research is therefore needed to determine whether better management of common COPD comorbidities, such as cardiovascular disease, can decrease the risk for exacerbations. http://www.goldcopd.org.

Several post-hoc analyses provided further relevant clinical information: (1) The effect of roflumilast persisted even in the presence of concomitant treatment with ICS.109 (2) As reported in abstract form, roflumilast significantly decreased hospitalization due to severe exacerbations110 and that of moderate-to-severe exacerbations when added to tiotropium in highly symptomatic patients (modified MRC scale score ³2 at baseline).111 (3) Among frequent exacerbators treated with roflumilast, 32.0% still had frequent exacerbations after 1 year of treatment, as compared to 40.8% of placebo-treated patients (p=0.0148). In this study, an exacerbation was defined as worsening for ≥2 consecutive days for ≥2 of the major symptoms (dyspnea, sputum volume, or sputum purulence) or worsening of any 1 major symptom together with any 1 minor symptom (sore throat, colds, fever without other cause, increased cough, or increased wheeze).81, Finally, 2 more recently developed LAMAs, aclidinium and glycopyrronium bromide, have also been shown to significantly decrease the frequency of exacerbations (defined as worsening of 2 or more major symptoms for at least 2 consecutive days or worsening of any 1 major symptom together with any minor symptom for at least 2 consecutive days) in patients with COPD versus placebo.82,83.

Eur Respir J. Inflammation coupled with mucus pooling in the lungs becomes a breeding ground for bacteria. In a cohort of 23,971 United States military veterans, being an ex-smoker rather than a current smoker significantly reduced the risk of COPD exacerbations even after adjustment for age, comorbidity, markers of COPD severity and socioeconomic status (adjusted HR =0.78, 95% confidence interval (CI)=0.75-0.87).66 The exact mechanism is unknown although it should be noted that nicotine is a growth factor for non-typeable Haemophilus influenza, which is thought to be a major bacterial pathogen in at least some exacerbations. Comparison of tiotropium plus fluticasone propionate/salmeterol with tiotropium in COPD: a randomized controlled study. Chronic obstructive pulmonary disease (COPD) is associated with episodes of symptomatic deterioration termed exacerbations [].COPD exacerbations are amongst the commonest causes of medical admission to hospital [].Patients with frequent exacerbations [] have accelerated lung function decline [4, 5], worse quality of life [], are at increased risk of cardiovascular events [] and .

Those showing evidence in favor of the use of triple therapy include the following: (1) A study of 126 patients showed that the combination of tiotropium plus salmeterol/fluticasone resulted in significantly fewer exacerbations than either tiotropium or salmeterol/fluticasone over 12 months of follow-up (p<0.01).102 (2) A 12-week, randomized, double-blind, parallel-group, multicenter study that included 660 patients who received tiotropium plus either budesonide/formoterol or placebo twice daily, showed that triple therapy significantly decreased the risk for severe exacerbations (p<0.001) and the frequency of hospitalizations and emergency department visits (p=0.011) versus tiotropium alone.103 This latter study, however, lasted only 12 weeks, so results should be viewed with caution since it has been recommended that studies investigating COPD exacerbations should have a duration of at least 12 months because of seasonal variation in exacerbation frequency.63 (3) A recent observational study that included results from 3333 Medicare enrollees also showed that triple therapy with fluticasone, tiotropium, and salmeterol was significantly superior to tiotropium alone in reducing the risk for moderate exacerbations (HR=0.772, 95% CI=0.641-0.930) and any exacerbation (HR=0.763, 95% CI=0.646-0.949).

Anthonisen NR, Manfreda J, Warren CP, Hershfield ES, Harding GK, Nelson NA. Among current knowns we would include: (1) the realization of the important impact that exacerbations have upon the natural course of the disease and the prognosis and well-being of COPD patients, (2) that multiple risk factors for exacerbations have been established; and (3) thatresults from multiple clinical trials have shown that currently available treatments for COPD can decrease, but not abolish exacerbations. J Gen Intern Med. It is plausible that different individual thresholds and/or degrees of social support (as discussed above) confound the rate of exacerbations reported by any single patient.
