Overview

Asthma must be clinically differentiated from other conditions that cause recurrent cough and wheezing such as viral bronchiolitis, chronic obstructive pulmonary disease, congestive heart failure, vocal cord dysfunction, ACE inhibitors use and allergic rhinitis.[1][2]

Differentiating Asthma from other Diseases

Diseases Symptoms Signs Diagosis
Fever Cough Chest pain Wheezes Crackles Tachycardia Lab tests Imaging
Asthma - Dry/Productive - + - -
Bronchiolitis +/- Dry - + + +/-
COPD + Productive - + + +
Bacterial pneumonia + Productive + + + +/-
Pulmonary embolism +/- Bloody + + + +
Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia[10] - Dry - + - -
  • Pulmonary function test shows obstructive lung disease
Tuberculosis + Bloody + - - -
  • Sputum culture:
    • Three successive positive culture for M. tuberculosis confirms the diagnosis[11]
    • Presence of acid fast bacilli in sputum smear indicates high extent tuberculosis
  • CT scan may show:[13]
  • EKG may have abnormalities in case pleural effussion associated with TB.
Interstitial pneumonitis (Hamman - Rich syndrome) + Productive - - + -
Foreign body aspiration + Bloody + + - -
  • Chest X ray shows:
Pertussis + Dry - - -
  • No remarkable imaging findings
Congestive heart failure - Dry/Productive + while walking - - +
  • EKG to detect underlying cause
  • Chest x ray shows cardiomegaly
  • Echocardiography is done:
  • Although, many cases of recurrent cough and wheezing in children and adults are due to asthma, other conditions are often misdiagnosed as asthma.[1][6][5][4][3]
