Outline of Research at the Start

糖尿病性腎臓病(DKD)患者は、透析導入に至ると死亡率が増加するだけでなく、生存期間における身体機能の重度低下、健康寿命の損失が問題視されている。近年、腎機能の維持を目指した取り組みが求められており、その一つに身体活動量を高く保つことが腎疾患に対するリハビリテーションの観点から推奨されている。しかし身体活動量は、なぜ低下するか、その機序は十分に明らかにされていない。
そこで本研究は、DKD患者の身体活動量低下に活動時の疲れやすさ(易疲労性)が影響するか、また易疲労性の生体メカニズムには微小血管血流量の低下が影響するかを明らかにする。

Outline of Final Research Achievements

This study demonstrated that the presence of diabetic kidney disease (DKD) in patients with type 2 diabetes mellitus (T2DM) significantly increased muscle fatigability. In particular, fatigability (ΔMVCC) was independently associated with reduced physical activity, highlighting DKD's impact on mobility in T2DM patients.

Academic Significance and Societal Importance of the Research Achievements

本研究は、DKDがT2DM患者の筋疲労性を高め、身体活動低下を引き起こす可能性を初めて実証的に示した点で学術的意義が高い。筋疲労性は運動療法により改善可能であり、DKD合併T2DM患者への身体活動促進における新たな介入標的としての可能性が示唆された。透析予防や健康寿命延伸への応用が期待される点が明確な社会的意義である。
