Secondary organizing pneumonia causes

Table 3 Causes of Secondary Organizing Pneumonia with Relative Frequencies...

Bronchiolitis obliterans with organizing pneumonia (BOOP) is now called cryptogenic organizing pneumonia (COP) when the cause is idiopathic (50). When secondary to a CTD, such as RA or SSc, variable terminology is used. 

Bacterial resistance increases with antibiotic usage such that it is difficult to achieve an appropriate balance between antibiotic prescribing and minimizing resistance. Each time antibiotics are administered, the recipient is at increased risk of selection and carriage of resistant organisms that can be passed to others. This can lead to future antibiotic failure. Without antibiotic therapy, however, acute otitis media secondary to S. pneumoniae is less likely to resolve spontaneously than that from other causes. S. pneumoniae is increasingly resistant to penicillin, and penicillin-resistant S. pneumoniae is more likely to be resistant to multiple antibiotics. ...
