Abstract
Although lead intoxication is commonly mentioned as a cause of sideroblastic anemia, no well-documented case exists in the literature. We encountered a patient with sideroblastic anemia caused by lead-containing herbal medicine. A 34-year-old woman was admitted to our hospital with abdominal pain. She had taken herbal medicine for her general health. Anemia, hyperbilirubinemia, and elevated lactic dehydrogenase were found from the laboratory data. Bone marrow biopsy showed pathological ringed sideroblasts. Her serum level of lead was high and the lead content of the tablet was higher than permitted. We diagnosed her with sideroblastic anemia secondary to lead poisoning caused by herbal medicine. We stopped her from taking herbal medicine and she gradually recovered from anemia.
납중독은 이차성 철적모구성빈혈의 원인으로 알려져 있으며, 아시아에서는 한약 복용이 납중독의 중요한 원인으로 여겨지고 있다. 그러나 국내에서는 한약으로 인한 이차성 철적모구성빈혈의 발표가 없었다. 저자는 복통과 빈혈을 주소로 내원한 34세 여자 환자에 대해 혈청 납농도 및 복용하였던 한약의 납함량 조사를 통해 이차성 철적모구성빈혈을 진단하였고, 한약 복용 중지 후 특별한 치료없이 범혈구 감소가 서서히 회복된 증례를 경험하였기에 이를 보고한다.
