Outline of Research at the Start

腎血行動態評価には腎血漿流量(RPF)測定が必要だが腎専門施設でも検査が出来ない。また筋肉量が標準と大きく異なる患者の糸球体濾過量(GFR)評価法は未確立である。
そこで本研究ではメタボロミクスと既存データベース・検体バイオバンクを駆使し、新規のGFR・RPFバイオマーカーを探索し、日常診療で活用できるRPF推算式を作成し、フレイルなど筋肉量が極度に低下した患者の正確なGFRを評価法を開発する。

Outline of Final Research Achievements

In this study, GFR and RPF were measured, and novel RPF equation was created by using metabolome analysis, which was validated in Japanese patients treated by SGLT2 inhibitor. Among patients with small muscle mass, new GFR equation using psoas muscle index (PMI) in CT images was created and validated in patients with spinal cord injury or spinal cord injury or anorexia nervosa. CKD-EPIcr 2021 equation without race coefficient has been reported, however we revealed that the equation overestimates GFR among Japanese patients and Japanese coefficient of 0.908 was needed. In international collaboration study measuring GFR by inulin clearance, we clarified that CKD-EPIcys2021 could accurately estimate GFR in Japanese and Indians, although they have smaller body muscle mass compared with Caucasians or African Americans.

Academic Significance and Societal Importance of the Research Achievements

糸球体高血圧の評価には糸球体濾過量(GFR)に加えて腎血漿流量(RPF)を測定する必要があるが、ほとんどの腎専門施設でも検査が出来ず、RPF推算式は全く存在しなかったが、メタボローム解析により世界に先駆けてRPF推算式を作成した。血清クレアチニン(Cr)に基づくGFR推算式は筋肉量が標準と大きく異なる場合は適用できないが、CT画像の腸腰筋よりPMIを測定することで筋肉量が減少した患者における腎機能評価を可能とした。人種係数を用いないCKD-EPIcr式を日本人で適用する係数を作成し、ベジタリアンを含むインド人と日本人でもCKD-EPIcysは正確に腎機能評価できることを明らかにした。
