COPD EXACERBATION GOLD 2011

An exacerbation of COPD is an acute event characterized by a

worsening of the patient’s respiratory symptoms that is beyond

normal day-to-day variations and leads to a change in medication

SUBSEQUENT MORTALITY

Garcia-Aymeric et al, Thorax 2011;66:585e590.

COPD severity was associated with a higher rate of severe exacerbations

requiring hospitalisation, although severe exacerbations at any stage were associated

with a higher risk of short-term and long-term all-cause mortality

BIOCHEMICAL MARKERS OF CARDIAC DYSFUNCTION PREDICT MORTALITY IN

ACUTE EXACERBATIONS OF COPD

Elevated levels of NT-proBNP and troponin T are strong predictors of early mortality among patients admitted to

hospital with acute exacerbations of COPD independently of other known prognostic indicators

The pathophysiological basis for this is unknown, but

indicates that cardiac involvement in exacerbations of COPD may be an important determinant of prognosis

TARGETING THE LUNG ATTACKS

Current management strategies for acute asthma and ECOPD within and subsequent to

discharge from hospital are suboptimal

We suggest that the term ‘lung attack’ may resonate more with patients and the broader

community

TIOTROPIUM IMPROVES LUNG FUNCTION IN PATIENTS WITH SEVERE ASTHMA:

a randomised controlled trial

The addition of once-daily tiotropium to asthma treatment including high dose ICS plus LABA,

provides significant improvements in lung-function over 24 hours in patients with

inadequately controlled, severe, persistent asthma

Long-term studies are needed to assess patient

reported outcomes and exacerbation rates.

Castro M et al. Am J Respir Crit Care Med 2010;181:116–24.

This study demonstrates that BT provides clinically meaningful improvements in severe exacerbations requiring corticosteroids, ED visits, and time lost from work/school during the post-treatment period in patients with severe

and inadequately controlled asthma, together with improvements in quality of life.

We conclude that the increased risk of adverse events in

the short-term after BT is outweighed by the benefit of BT that persists for at least 1 year. BT offers clinicians a novel, procedure-based, add-on therapy beyond the current use of

high-dose ICS and LABA to decrease the morbidity of severe asthma.

Summary • Palvoratene appears to have low toxicity

• In placebo treated patients, 2 regions of interest in the lower lung (lower half and lowest quartile) showed faster disease progression across most measures

• ITT analysis in whole lung

– Palvarotene efficacy did not differ from placebo

• Post hoc analysis in the lower lung – Palvarotene was associated with less worsening over time in most

outcomes

• These observations require confirmation using more detailed analysis of emphysema progression in different parts of the lung

• If confirmed, the observations from this hypothesis-generating study require testing in patients with lower lung emphysema

Conclusions

Lebrikizumab treatment was associated with

improved lung function.

Patients with high pretreatment levels of serum periostin had greater improvement in lung function with lebrikizumab than did patients with low periostin levels.

REDUCTION OF MORBIDITY AND MORTALITY BY STATINS, ACE INHIBITORS, AND ARBS IN

PATIENTS WITH COPD

These agents may have dual cardiopulmonary protective properties, thereby substantially altering prognosis of patients with COPD.

These findings need confirmation in

randomized clinical trials.

Β-BLOCKERS MAY REDUCE MORTALITY AND RISK OF EXACERBATIONS IN PATIENTS WITH

CHRONIC OBSTRUCTIVE PULMONARY DISEASE

Rutten FH et al, Arch Intern Med. 2010 May 24;170(10):880-7

Treatment with beta-blockers may reduce the risk of exacerbations and

improve survival in patients with COPD, possibly as a result of dual

cardiopulmonary protective properties
