Furthermore, M. pneumoniae may also precede the onset of asthma, because patients with an acute infection by M. pneumoniae, followed by the development of asthma, have significant improvement in lung function and asthma symptoms after they are given antimicrobial treatment against M. pneumoniae.

In many cases, significant asthma may not even occur until the respiratory infection is in its waning stage, and the person is ...

Asthma is characterized by recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing. [21] Sputum may be produced from the lung by coughing but is often hard to bring up. [22] During recovery from an asthma attack (exacerbation), the sputum may appear pus-like due to high levels of white blood cells called eosinophils. [23]
While some issues, such as a recent history of exposure to substantive toxins, can foretell the diagnosis, for a patient with dysphagia the diagnosis may be less obvious, as the dysphagic patient may have caustic gastric contents damaging the lungs which may or may not have progressed to bacterial infection.
