Lung infection with sever asthma?

More common: Severe asthma reduces clearance of mucous and microoganisms (viruses & bacteria) from the lung. Long-standing severe asthma may lead to structural changes in the airway that compromise mucous clearance even more. Poor clearance of mucous & microorganisms from the breathing tubes is a clear risk factor for bronchitis and pneumonia. In children the leading risk factor for pneumonia is asthma.

Inhaled steroids: Recent studies have shown that asthmatics who employ inhaled steroids have an increased risk of pneumococcal pneumonia.
