Outline of Final Research Achievements

Pentosidine, a representative AGE, is reported to be involved in all-cause mortality, incidence of cardiovascular diseases, and abnormal bone metabolism in patients with chronic kidney disease (CKD) and likely a beneficial biomarker.To determine valuable insights on the role of AGEs in patients with normal or mild renal dysfunction, we collected the 3-year data from the annual health check-ups, and cross-sectional analysis was conducted on the relationship between serum pentosidine and renal function.Serum Pentcidine level was significantly increased with decreasing eGFR. Furthermore, estimated GFR decline has statistically significant relationship with higher pentosidine concentration and the odds ratio (95% confidence interval) was 1.58 (1.31-1.91). Conversely, HbA1c was not a significant factor. Therefore, serum concentration of pentosidine has a strong relationship with renal function from early stage rather than diabetes mellitus.

Academic Significance and Societal Importance of the Research Achievements

筆者らは、進行した腎不全患者において、血糖よりも腎機能低下による影響が大きいAGEsがあることを報告してきたが、正常ないしは軽度の腎機能障害患者において、CKDがペントシジン濃度に与える影響に関する知見は少なかった。今回の研究により、血中ペントシジン濃度に与える影響は、HbA1cよりも腎機能低下の影響が大きいことが解明された。血中ペントシジン濃度は生存率、心血管疾患、骨代謝異常などに関与することが知られており、腎保護の重要性が改めて明らかになった。さらに、今後、腎不全におけるAGE産生経路についてより研究を深めることにより、CKD患者の予後改善へつながる第一歩となる研究であったと考える。
