Recurrent bronchitis

Definition
cough lasting more than 3 weeks and occurring 3 times in the last 12 months ,
 * it should be considered a manifestation of another underlying disease (it is actually a diffuse prolonged cough),
 * some children with recurrent bronchitis later develop asthma or COPD.

Etiology
In most cases these are conditions after acute respiratory infections, we must think, in particular - asthma, congenital malformations of the respiratory system , foreign bodies in DC, bronchiectasis , immune defects, the presence of focal infections ( adenoid vegetation , chronic tonsillitis, sinusitis), it is necessary to exclude tuberculosis and cystic fibrosis , the cough is noisy, disappears in sleep.
 * other causes - irritants (chemicals, aspirations in GER, smoke, polluted air), primary ciliary dyskinesia , lung abscess , heart defects ,
 * psychogenic cough - it lacks a detectable somatic cause (it is practically a tick),

Diagnosis
it is necessary to look for individual causes, because one of the most common causes is asthma - we routinely perform bronchoprovocation tests (reveal bronchial reactivity after inhalation of histamine, acetylcholine or after a five-minute run), it is also good to perform rhinomanometry - it will rule out a problem of nasal patency as a cause.
