In childhood systemic lupus erythematosus patients, renal involvement is closely related to mortality and morbidity of the disease. Therefore early diagnosis and treatment are essential to improving prognosis. We saw a child who had hematuria, albuminuria, anorexia, fatigue, and light hyper sensitiveness. He was diagnosed as lupus nephritis (WHO Class II+IV) and treated with ACE inhibitor and steroid therapy for 12 months. However, clinical improvement was not shown. So we treated him with herbal formula (Jasinwhalhyul-tang: Zishenhuoxue-tang) and steroid therapy. After 17 months of treatment, hematuria disappeared and clinical symptoms and albuminuria had improved significantly.
