[An autopsy case of interstitial pneumonia probably induced by Sho-saiko-to].
A 66-year-old woman had been treated for 3 years by her local physician with Sho-saiko-to for chronic hepatitis C virus (HCV) infection and liver cirrhosis. She was admitted to our hospital because of cough, fever, and infiltrative shadows on chest x-ray films. Sho-saiko-to-induced pneumonitis was diagnosed and steroid therapy started. Though a temporary improvement was observed, interstitial pneumonitis relapsed and the patient died of respiratory failure and liver dysfunction. Autopsy findings showed diffuse alveolar damage and honeycombing. Furthermore, reverse-transcriptase polymerase chain reaction techniques detected HCV-RNA in specimens of fibrotic lung tissue. For comparison, HCV-RNA was not histologically detected in lung tissue specimens from 4 control subjects who were positive for HCV antibodies but who did not have interstitial lung disease. It was speculated that the progression of interstitial pneumonia in the present case may have been caused by HCV in combination with Sho-saiko-to-induced lung injury.
