【 要旨 】 レニン-アンギオテンシン-アルドステロン系(renin-angiotensin-aldosterone system;RAAS)は慢性腎臓病(chronic kidney disease;CKD)により著しく活性化され,高血圧のほか,CKDに関連した種々の病態に関わる.RAASは骨代謝異常にも関連し,CKDによる骨材質特性の異常にも影響することが考えられる.臨床的にRAAS阻害薬の使用は透析患者の骨折発症の減少に関連することも示唆されており,RAASへの介入は骨粗鬆症治療が十分行えないCKD,透析患者に有効な治療となりうる可能性がある.

[ Summary ] The renin-angiotensin-aldosterone system (RAAS) is activated in cases of chronic kidney disease (CKD) and associated with various CKD-related disorders including abnormal bone metabolism. Animal studies showed that use of an angiotensin Ⅱ type 1 receptor blocker ameliorated kidney damage-induced reduction of bone volume as well as impairment of bone elasticity. In some clinical studies, use of RAAS inhibitors showed reduced incidences of bone fractures in maintenance hemodialysis patients. Use of anti-osteoporotic treatment is limited in CKD patients, especially those undergoing dialysis treatment. Intervention for RAAS may be one of the therapeutic targets for kidney damage-induced abnormal bone metabolism.
