Kampo Treatment for Intractable Iron-Deficiency Anemia Due to Gastrointestinal Side Effects of Oral Iron Supplement / 日本東洋医学雑誌

ABSTRACT

Iron deficiency anemia is the most frequently experienced anemia in common daily practice. It is often difficult to treat due to gastrointestinal side effects of iron drugs. We report a difficult case of iron-deficiency anemia with intolerance to oral iron supplementation, which was resolved by concomitant use of Kampo. Thirty-five-year-old woman visited us because of menoxenia continuing since she was 17 years old. Although tokishakuyakusan with kakobushimatsu (processed aconite root powder) had been administered, remarkable anemia such a low hemoglobin (Hb) level (7.8 g/dL) was observed. After we added an oral iron agent for 5 months, the hemoglobin level increased to 12.8 g/dL, and epigastric discomfort appeared. Therefore, we discontinued iron agent and switched to Kampo monotherapy, but anemia gradually worsened again. Following intravenous iron infusions could not improve the iron deficiency state. Then we administered ryokeijutsukanto with kojinmatsu (ginseng powder) and lower dose of oral iron agent than before, with reference to sinshato described in “Sokeitei Ijishogen” written by Nan'yo Hara. After administration, Hb and serum ferritin level improved from 11.6 g/dL and 4.0 ng/mL to 12.3 g/dL and 32.0 ng/mL, respectively. After that, the iron metabolism marker kept stable, although the oral iron agent had been further reduced. The main indications of sinshato are palpitation, shortness of breath, dizziness and edema according to the original text. These symptoms can be interpreted as ones related to anemia. In our case, it was suggested that prescription composition of sinshato promoted iron absorption and improved anemia.
