ABSTRACT

Heme oxygenase-1 (HO-1) is a heme-degrading enzyme with antioxidant activity and has been reported to be useful for the diagnosis and prognosis prediction of interstitial pneumonia. The case was an 83-year-old male. The patient was hospitalized for drug-induced lung injury due to abiraterone acetate used to treat prostate cancer. Although the patient’s condition stabilized temporarily after steroid pulse therapy, the lung injury was aggravated due to influenza A infection during steroid titration. He died without improvement. This case is very rare, in that serum HO-1 levels not only showed changes similar to those of KL-6 and SP-D, but also were more closely linked to disease activity than both biomarkers. We also report the distribution and degree of HO-1 expression in lung cells.
