title: [A case of idiopathic interstitial pneumonia with cytomegalovirus infection].
abstract: A 67-year-old female was admitted to our hospital because of fever, dry cough, and exertional dyspnea. The findings of chest X-ray, transbronchial lung biopsy, and bronchoalveolar lavage were compatible with the diagnosis of idiopathic interstitial pneumonia. Prednisolone was administered and she felt better for a while. However, she developed severe dyspnea, and marked diffuse infiltrative shadows were observed on chest X-ray after 3 months of steroid therapy. In spite of pulse therapy with methylprednisolone, she died of severe respiratory failure. Complement fixation test and IgG antibody enzyme immunoassay for cytomegalovirus were positive, but there was no change the titers between admission and death. IgM antibody was negative. The lung findings at autopsy compatible with usual interstitial pneumonia and diffuse alveolar damage, moreover, cytomegalovirus infection was observed. We consider that recurrent cytomegalovirus pneumonia had been present due to secondary immunodeficiency caused by administration of steroid hormones.
