 70 years old male with a history of dyspnea for 10 years
 Presenting with dyspnea with white productive
sputum, no fever or URI symptoms
 Skin test +ve for house dust mites, pollens, and cockroaches
 Non-smoker
 Is it COPD or Asthma ?
Obstructive Lung Diseases
Integrity and elasticity of lung : DESTROYED
Poor elastic recoil: Air trapping (Hyperinflation)
Problem is with expiration.
Patient has to force the air out using abdominal & intercostal muscles: EXERTION
In Spirometry: FEV1/FVC is decreased.

Assessment of Exacerbation Risk
- COPD exacerbations are defined as an acute worsening of respiratory symptoms
that result in additional therapy.
- Classified as:
 Mild (treated with SABDs only)
 Moderate (treated with SABDs plus antibiotics and/or oral corticosteroids)
 Severe (patient requires hospitalization or visits the emergency room). Severe
exacerbations may also be associated with acute respiratory failure.
- Blood eosinophil count may also predict exacerbation rates (in patients treated with
LABA without ICS).

Co-suspension technique
• New formulation:
• Drug crystals are suspended in HFAbased propellant
by engineered low-density phospholipid particles.

inhalers for multi-drug dosing in the treatment of respiratory diseases. Respir Med. 2018 Jan

ADVANTAGES
1. Porous particle + drug crystal mixtures remain afloat instead of
sedimenting
2. Prevents flocculation/aggregation of drug particles
3. Decreased DDI/DCI
4. Size: 2-3 um: optimum
5. Low spray velocity HFApropellant: decreased dysphonia
1. LABA+LAMA has greater improvement in quality of life
compared to placebo or its individual bronchodilator
components

Other key updates: GINA 2018
1. New Section added: Perimenstrual (catamenial) asthma
• Asthma worse perimenstrually in ~20% women
• More common in women with high BMI; often have dysmenorrhea and shorter cycles.
• Add-on treatment: OCP and/or LTRA may be helpful
2. New therapy added: HDM-SLIT (house dust mite – sublingual IT) Therapy
• When medication is discontinued, symptoms may recur. This is where allergen immunotherapy
(AIT) comes into play
• Repeated doses of a specific relevant allergen for the treatment of IgE-mediated allergicdisease
3. Evidence A: recommendation against stopping ICS during pregnancy
• Stopping ICS increases the risk of exacerbations in pregnancy
