In December 2006, a 55-year-old-man was given a diagnosis of adenocarcinoma of the lung with multiple brain metastases. Systemic chemotherapy was given consisting of carboplatin plus paclitaxel and carboplatin plus gemcitabine. But with the increase of the brain metastases, he was admitted in February 2008.

Marked increase of serum hepatitis C virus (HCV) RNA titer during treatment with high-dose prednisolone in a case of polymyositis.

A 70-year-old Japanese woman with hepatitis C virus (HCV) infection was diagnosed with polymyositis and treated with high-dose prednisolone (PSL). The serum alanine aminotransferase (ALT) level increased from 78 to 345 U/l 1 week after initiating treatment, although the polymyositis settled promptly. Furthermore, the serum HCV RNA level increased markedly from 110 to 850 kIU/ml 3 weeks after starting treatment.
