Research Abstract

重症の心筋症による心不全患者を対象として、心不全増悪に関連する自己抗体が含まれるIgG分画を除去すべく免疫吸着を行い、その有効性・安全性を確立すること、また、自己抗体・サイトカイン・酸化ストレスマーカーと本治療効果との関連を評価することを目的とし本研究を行った。
現在まで7例に本治療を行い、有害事象なく治療することができた。本治療により抗β1-AR抗体価(前27.8±5.0, 後18.7±5.5 U/ml (p<0.01))や、IgG3分画(前74.5±38.2, 後16.0±8.8 mg/dl, p<0.01)の有意な減少を認め、3例の心不全症状改善効果を経験した。
諸検査指標において左室駆出率(前22.8±6.1 後29.1±9.1% (p<0.05))、心拍出係数(前1.71±0.40 後1.97±0.41 l/min/m2)の早期改善効果が認められた。さらに、免疫吸着前後でd-ROM testにて酸化ストレスレベルを測定したところ、有意な酸化ストレスレベルの改善を示し(前392.7±17.0後314.1±22.0 CARR units (p< 0.05))、この酸化ストレスレベルは左室駆出率および肺動脈楔入圧と良好な相関を示した。
また、血中TNF-αも治療にて有意に低下し(前1.41±0.81、後0.17±0.45μg/dl、p<0.01)、この減少度はd-ROM testによる酸化ストレスレベルの減少度と良好な相関を認めた(p<0.05)
しかし、抗β1-AR抗体価、左室駆出率、酸化ストレスレベルは12ヶ月後には治療前のレベルにまで戻った。
