Summary:The accumulation of aluminum in the tissue, as a causative factor of encephalopathy and osteomalacia, is a serious problem in managing patients undergoing hemodialysis (HD) for a long term. In recent years, there have been some reports, supporting the effectiveness of Desferrioxamine (DFO). However, the doses of administration have not defined as yet. This paper is a case report that a patient, probably suffering from aluminum osteomalacia, was successively treated by both the infusion of DFO and protein leaking hemodialyzer (PLHD). Case; 24 years old female. She was first treated by HD in Mar. 1978 and well maintained for 5 years until 1983 when she began to complain of bone pain. In Feb. 1984, her left humerus was fractured, followed by right femur fracture 3 months later. She was managed by conventional treatment, but the course was unsatisfactory. From Oct. 1984, she was treated by DFO (1000mg) and PLHD (5 hours). Serum levels of aluminum increased 7.20±1.8 times as compared with pretreatment levels and the amounts of removal by PLHD was 71.7±5.3% (N=11). The decrease of serum aluminum level was noted 4 months after the initiation of treatment. Clinically, bone pain was disappered 1 month later and she could ambulate from Dec. 1985. As for serum level of Fe and ferritin, the level of ferritin was decreased slightly by PLHD. In conclusion, the infusion of DFO in combination with PLHD was effective against aluminum osteomalacia. 透析患者におけるアルミニウム(以下Al)の体内への蓄積は, 透析脳症, 骨軟化症などに影響するものとして問題になっている。最近, Alの除去に対しては, Desferrioxamine(以下DFO)が有効とする報告がみられるが, 使用方法は, 各施設様々である。当院でも, Al骨症と思われる透析患者に対し, DFOの投与と, タンパクリーク型ダイアラィザーによる血液透析(以下PLHD)を施行し, 良好な結果をえた。症例は24才女性。昭和53年3月血液透析(以下HD)導入, 現在週3回, 4, 5~5時間のHDを施行している。昭和58年頃より骨痛の訴えがあり, 昭和59年2月, 左上腕骨病的骨折, 同年5月, 右大腿骨病的骨折, ギブス固定により治療を続けるが, 骨再生は認められず, 同年10月より, Al骨症を疑いDFO投与とPLHDによる治療を開始した。DFOは, 週の中間透析日の終了後1000mgを点滴し, 次回に5時間のPLHDを施行した。血清Al値は, DFO投与により7.20±1.8倍の上昇が見られ, PLHDによる除去率は, 71.7±5.3%(n:11)と良好な結果がえられた。また治療開始後4ケ月頃より血清Al値の低下が見られた。臨床的には治療開始後1ケ月頃より骨痛の軽減, 骨再生が認められ, 昭和60年2月より歩行可能となり, 現在外来通院にて治療を継続している。また, PLHDによる血清鉄, フェリチンの変動は認められないが, DFO治療継続中にフェリチン値が低下してきており, 若干の除去があるものと思われる。以上の結果より, Al除去およびAl骨症の改善に, DFOの投与とPLHDの併用が有効であると考えられる。
