“Over 47 years ago, when the author graduated from
medical school, the only therapies for COPD were
antibiotics for pneumonia, potassium iodide used as a
mucus thinner, and combination products containing
ephedrine, a small amount of theophylline, and a minor
amount of sedative to deal with the side effects of
ephedrine. Inhaled isoproterenol began to be used in
the early 1960s. In that era, oxygen was considered
contraindicated, and exercise was prohibited for fear of
straining the right heart. Corticosteroids were almost
never used, even in cases of exacerbations of COPD.

Defining COPD
• The CIBA guest symposium of
physicians in 1959 : defining chronic
bronchitis and emphysema
• William Briscoe in 1965: first coined
the term COPD

The ‘GOLD’ initiative
• GOLD 1997
• Defining COPD with spirometric criteria and
classification according to the degree of
reduction of FEV1
• COPD: FEV1/FVC <70%
FEV1
Degree of obstruction: GOLD I
> 80 %
GOLD II > 50 %
GOLD III > 30 %
GOLD IV < 30 %

Significant facts
• Understanding the genesis of symptoms
Air trapping and dynamic hyperinflation and that
(the degree of obstruction have no co-relationship with the symptomatology)
• Assessment of COPD needs
a) spirometric and lung functional
b) functional ability
c) health status and quality of life
doctor centric disease centric patient centric

More facts: recognition of
• The importance of health status: CAT being
the most useful discovery
• The importance of COPD exacerbations in the

“Aclidinium Bromide Improves Lung Function in a
Wide Range of Patients With Moderate to Severe
COPD: Pooled Subgroup Analysis of the ACCORD COPD
I and II and ATTAIN Trials”
‘These data show that ACL400 produces clinically and statistically
significant improvements in lung function from Week 1 through
Week 12. These improvements were seen regardless of sex, age,
smoking status, COPD severity, concomitant ICS, or bronchodilator
reversibility status. A larger improvement in lung function was seen
with ACL400 in patients with bronchodilator reversibility than
without.’

Indacaterol may be better than salmeterol, formoterol and tiotropium in
increasing trough FEV1 in COPD with no evidence of tachyphylaxis.
Milveterol has been found to be safe and well-tolerated in asthma, with
efficacy comparable to salmeterol. Its role in COPD is yet unexplored.
Vilanterol has been found to be safe and effective in both asthma and COPD
patients.

Anti MMPs efforts
• (MMPs), a class of Zinc endopeptidase, has been found
to play an important role (1).
• They are found to be active and up-regulated in
emphysema induced by smoking (2,3,4).
• The pulmonary expressions of different MMPs are found
increased in several human observations in COPD (5, 6, 7).

Anti MMPs therapy: doxycycline
• Acts by binding to the active zinc site and also
by inactivating calcium ion site leading to
conformational changes resulting in loss of
enzymatic activity (1)
• Available in the market with good safety
record with many documented long term uses
• Its anti MMPs use in periodontal disease has
been recognized by USFDA (2)

Contains several nutriants as
• Diindolylmethane potent immunomodulator
• Selenium, vitamin C anti oxidants
• Glucoraphanin sulforaphane, an anti-cancer
compound,
• Indole-3-carbinol boosts DNA repair in cells and
appears to block the growth of cancer cells

Significance of LVDD in COPD
• The frequency and the duration of hospitalization
are more in the presence of LVDD in COPD
• LVDD may manifest myocardial ischemia not
otherwise apparent the treatment of which may
be worthwhile
• LVDD can cause COPD exacerbation
• Treatment of LVDD leads to improved functional
ability

Treatment of infection
• Infection according to ‘vicious cycle
hypothesis’ through smoking induced
reduction in the innate defense.
• Persistence of microbes leading to fibrotic or
destructive response
• Long term antibiotic therapy benefits them

What will happen after five years or
next decade
• Practice of effective metabolomic, genomic, and
other markers
• Clear identifications of different subsets of
patients and customization of treatment
• Revolution in lung volume reduction technology
• Innovation of re-remodeling of airways
• Great reduction in mortality and morbidity with
improvement of the quality of life
