title: [Acute lymphoblastic leukemia complicated by type C hepatitis during treatment and further by acute interstitial pneumonia due to sho-saiko-to in 7-year-old].
abstract: The patient was complicated by type C hepatitis considered dur to blood preparations during the treatment of acute lymphoblastic leukemia. On administration of Sho-saiko-to, the white blood cell count decreased. When the drug was administered again, interstitial pneumonia developed concurrently. The case is a 7-year-old boy. He is the youngest to suffer interstitial pneumonia due to Sho-saiko-to in Japan, showing the possibility that interstitial pneumonia occurs even in childhood. A study of the IgG subclass at the time of the development of interstitial pneumonia in the affected child showed an imbalance of the subclass, with an increase in the percentage of IgG1 and IgG3, and a decreased in the percentage of IgG2 and IgG4. With improvement in the symptoms thereafter, however, the IgG subclass normalized. Thus it is possible that the IgG subclass is concerned with the development of interstitial pneumonia in this case. So, making careful observations is needed in administering Sho saiko-to to children with type C hepatitis who use various immunosuppressants.
