In idiopathic interstitial pneumonia, antibiotics are not required, and hormone selection is not suitable for every patient, so there is no question of comparing the efficacy of hormones with antibiotics versus hormones alone. If a patient requires hormone therapy and has a co-infection, the two can be used in combination, but of course the combination is more effective than the use of hormones alone, for example, if the patient has a combination of skin and soft tissue infections, how can the infection be controlled without the use of antibiotics? If the patient has no evidence of infection and the diagnosis is not clear, and antibiotics are started just based on chest imaging, the doctor obviously has a problem with misuse of antibiotics. If the diagnosis is clear that it is idiopathic interstitial pneumonia and the doctor gives antibiotics, again there is antibiotic abuse, or the doctor simply does not know how to treat idiopathic interstitial pneumonia, suggest that the patient change doctors or hospitals.
