Q

COPD def

A

common, preventable and treatable disease that is characterized by persistent respiratory symptoms and airflow limitation that is due to airway and/or alveolar abnormalities usually caused by significant exposure to noxious particles or gasses.

71
Q

Risk factors for COPD

A

1: cig smoking

-occupational dust and chemicals
-environmental tobacco smoke
-indoor and outdoor air pollution
-genes (alpha-1 antitrypsin deficiency)
-infections 9HX of severe childhood resp infections)
-socio-economic status
-AGING populations

72
Q

Clinical Presentation of COPD

A

-dyspnea; progressive, persistent and characteristically worse with exercise
-cough; often 1st symptom of COPD

Q

Assessment of Exacerbation Risk

A

-COPD exacerbations are defined as an acute worsening of respiratory symptoms that result in additional therapy
–> mild: treated with SABA only
–> moderate: treated with SABA + antibiotic and/or oral corticosteroids
–> severe: pt requires hospitalization or visits the ER. severe exacerbation may also be associated with acute respiratory failure
-blood eosinophil count may also predict exacerbation rates

88
Q

Pt is HIGH exacerbation risk if:

A

-2 or more exacerbations in the last year
OR
-1 or more exacerbation in the last year that led to hospitalization

89
Q

pt is NOT considered high exacerbation risk if:

A

-NO exacerbations in the last year
OR
-1 exacerbation in the last year that did NOT lead to hospitalization

90
Q

COPD pts are at increased risk for:

A

-cardiovascular diseases (~30% have heart failure)
-osteoporosis
-respiratory infections
-anxiety and depression
-diabetes
-lung cancer
-bronchiectasis

91
Q

ICS role in stable COPD tx

A

*if eosinophil count > 300 cells/uL and > 100 (+ exacerbations)
-long term use = increased risk of pneumonia
**asthma hx or features of asthma present –> ICS combo therapy indicated

92
Q

Factors to consider when initiating ICS tx (strong support)

A

-hx of hospitalization for execrbations
-> 2 moderate exacerbations of COPD per year
-blood eosinophils > 300
-hx of or concomitant asthma

93
Q

non-pharm management of COPD

A

**smoking cessation
-vaccinations (influenza, pneumococcal, Tdap, Covid)

94
Q

Asthma-COPD overlap

Persistent airflow limitation with several features usually associated with asthma and several features usually associated with COPD. It is identified by the features that it shares with both asthma and COPD

95
Q

Asthma-COPD overlap features

-may have had symptoms in early childhood
-persistent airflow limitations, not fully reversible, and with variability
-often has hx of childhood asthma, allergies, exposure to smoke or other irritants or fam hx of asthma
-tx partially decreases symptoms
-chest X-ray similar to COPD
-exacerbations more common than in COPD alone
-eosinophils and/or neutrophils in sputum
-comorbidities may lead to further impairement

96
Q

Acute COPD exacerbation

A

-acute worsening of respiratory symptoms that results in additional therapy or medications
Patho: increased airway inflammation, increased mucus production, increased mucus production, marked gas trapping & increased eosinophils in significant numbers of pts

97

-increased cough and wheeze
*lasts about 7-10 days

98
