A case having initial onset of bronchial asthma, probably induced by prolonged mycoplasmal infection, accompanied with concurrent highly suspicious chlamydial infection

Abstract

A 37-year-old man who had had no allergic history was admitted to our hospital complaining of high fever, a dry hacking cough and dyspnea. Mycoplasma and Chlamydia mixed infection was diagnosed because of increased antibody titers to simultaneous Mycoplasma pneumoniae and Chlamydia psittaci, however only the Mycoplasma pneumoniae antibody titer was not decreased during the over six months. One month after the onset, bronchial asthma was diagnosed subsequently from for the clinical symptoms of wheeze and cough. Clinical studies of the dual infection and the possibility of Mycoplasma pneumoniae as the probable antigen of bronchial asthma were discussed.
