What is asthma? How is asthma diagnosed?

Symptomatic asthma – PFT, Asymptomatic – provocation challenge test Symptoms: episodic breathlessness, chest tightness, wheezing, cough – incited with allergen exposure, seasonal variation. There is a family history of asthma and allergy. History of variability in symptoms. Physical examination – wheezing may be present, silent chest in severe asthma

Lung functions – FEV1, FVC, PEFR

PEFR – 1. Confirm diagnosis of asthma (>20% or >60l/min improvement post-bronchodilator or diurnal) 2. For monitoring and control

Methacholine challenge test/ histamine challenge test/ mannitol/exercise challenge test (sensitive test – negative test rules out asthma, false-positive – allergic rhinitis, CF, bronchiectasis, COPD)

Sputum eosinophilia, Feno

Total Ig E – not diagnostic of atopy

SPT – low cost and high sensitivity through false positive is high

Rule out DD –

FOREIGN BODY INHALATION

VOCAL CORD DYSFUNCTION

LVF

COPD

CF/BRONCHIECTASIS

How do u assess the severity

Controlled
(ALL MEASURES)
Partly controlled
(1-2)
Uncontrolled
Daytime symptoms<2 /week3 OR MORE
Limitation of activityNone
Nocturnal awakeningNone
Need for reliever<2 /week
FEV1N<80%

Assessment of future risk –

  1. Poor control of symptoms
  2. Frequent exacerbations

Asthma is an inflammatory disease with the involvement of airway cells (like mast cells, eosinophils, t lymphocytes, and dendritic cells) and structural cells (airway epithelial, endothelial cells, smooth muscle cells). Chemokines, cysteinyl leukotrienes, cytokines, histamine, and NO are mediators that act on these cells.

Airway narrowing is caused due to – smooth muscle contraction, airway edema, mucus hypersecretion, airway remodeling.

What signs tells a person that asthma is worsening ?

1. Breathlessness

2. Talks in 

3. Alertness

5. Respiratory rate

6. Accessory muscles of respiration
