*3.2.1* C. Pneumonia*-related chronic diseases*

The connection between chronic persistent *C. pneumoniae* infection and chronic inflammatory disorders is still up for debate. In addition to contributing to respiratory tract infections, a growing body of research suggests that *C. pneumoniae* may also be involved in the pathogenesis of several inflammatory diseases, including atherosclerosis, arthritis, asthma, chronic obstructive pulmonary disease (COPD), lung cancer, and some neurological conditions such as Alzheimer's disease, multiple sclerosis, and schizophrenia [98]. Among them, patients who have asthma/COPD and present with symptoms of confirmed *C. pneumonia* airway infection should be treated according to the treatment recommendations for acute respiratory infections mentioned above. Due to a paucity of data, there are presently no recommendations for treating any other chronic diseases associated with *C. pneumoniae* infection, other than asthma and COPD [3, 72, 98].
