Abstract <要旨> 【目的】本研究は, 血液透析患者の運動耐容能と透析中のΔBVの推移の関連を検討した. 【方法】血液透析患者20名を対象に心肺運動負荷試験を実施し, 運動耐容能の指標である嫌気性代謝閾値 (VO2AT) と最高酸素摂取量 (VO2peak) を測定した. また心肺運動負荷試験実施の翌週以降の透析で, 透析開始から終了までのΔBVの回帰式の傾きを算出した. そして各運動耐容能の指標とΔBVの傾きとの関連を検討した. 【結果】VO2AT (r=0.44) とVO2peak (r=0.54) は, どちらも透析中のΔBVの傾きと有意な相関を認めた (p<0.05) . また総除水率を制御変数とした偏相関係数を検討した結果, ΔBVとVO2peak (r=0.47) との間に有意な関連を認めた (p<0.05) . 【考察】運動耐容能が高い対象ほど, 透析中のΔBV低下が小さかった. 運動耐容能と透析中のΔBVとの間に何らかの関係性が示唆されたが, メカニズムは不明であり, 今後の検討が必要である.

Abstract <Summary> [Objectives] The purpose of this study is to investigate the relationship between the exercise tolerance measured by cardiopulmonary exercise testing (CPX) and the Δ Blood volume (ΔBV) during dialysis in patients with hemodialysis. [Methods] Anaerobic threshold (VO2AT) and peak oxygen uptake (VO2peak) that are indicators of exercise tolerance were measured by CPX from 20 hemodialysis patients. The slope of the regression equation of ΔBV from the start to the end of dialysis was calculated in hemodialysis session after the next week of CPX. In addition, the relationship between the slope of the regression equation of ΔBV and VO2at or VO2peak was examined by Pearson's correlation coefficient. [Results] Both VO2AT (r = 0.44) and VO2peak (r = 0.54) were significantly correlated with the slope of ΔBV (p <0.05). Result of partial correlation coefficient that fluid removal rate is control variable, VO2peak (r = 0.54) had significant correlation with the slope of ΔBV (p <0.05). [Discussion] The subjects with higher exercise tolerance had lower ΔBV reduction during dialysis. Because of VO2peak reflects the blood supply capacity, the higher the exercise tolerance of the subject, the more the circulating blood volume to the peripheral tissue was retained, and ΔBV reduction might be prevented.
