  • DNA damage in proximal tubules triggers systemic metabolic dysfunction through epigenetically altered macrophages

    Nishimura E.S., Hishikawa A., Nakamichi R., Akashio R., Chikuma S., Hashiguchi A., Yoshimoto N., Hama E.Y., Maruki T., Itoh W., Yamaguchi S., Yoshino J., Itoh H., Hayashi K.

    Nature Communications 16 ( 1 ) 3958 2025年12月

     概要を見る

    DNA damage repair is a critical physiological process closely linked to aging. The accumulation of DNA damage in renal proximal tubular epithelial cells (PTEC) is related to a decline in kidney function. Here, we report that DNA double-strand breaks in PTECs lead to systemic metabolic dysfunction, including weight loss, reduced fat mass, impaired glucose tolerance with mitochondrial dysfunction, and increased inflammation in adipose tissues and the liver. Single-cell RNA sequencing analysis reveals expansion of CD11c+ Ccr2+ macrophages in the kidney cortex, liver, and adipose tissues and Ly6Chi monocytes in peripheral blood. DNA damage in PTECs is associated with hypomethylation of macrophage activation genes, including Gasdermin D, in peripheral blood cells, which is linked to reduced DNA methylation at KLF9-binding motifs. Macrophage depletion ameliorates metabolic abnormalities. These findings highlight the impact of kidney DNA damage on systemic metabolic homeostasis, revealing a kidney-blood-metabolism axis mediated by epigenetic changes in macrophages.

     概要を見る

    Background: The number of patients undergoing peritoneal dialysis (PD) in Japan has recently increased. However, Japanese guidelines for such patients’ education are not yet available. Therefore, we aimed to investigate the present status of patient education regarding PD in Japan. Methods: We used one questionnaire to perform two rounds of surveys (2019 and 2021) at institutes that managed ten patients or more on PD at the end of each year. We evaluated the facilities’ characteristics, catheter placement, PD guidance, educational content, education management, home-care environment, care of exit site, and bathing and retraining. Results: A total of 76 facilities (response rate: 26.8%) responded to the first survey, and 86 (response rate: 28.3%) to the second. The incidence of peritonitis in the valid responding institutes was 0.21 per patient-year in 2019 and 0.19 per patient-year in 2021, similar to the incidence of 0.20 per patient-year in 2022 reported by the Japanese Society for Dialysis Therapy Renal Data Registry. This indicates that the valid responding institutes may have been representative of the typical Japanese clinical level in terms of PD. In terms of catheter placement, exit-site positions were preoperatively marked by nurse in 41% of facilities in 2019 and in 37% in 2021. In terms of PD guidance, regarding the timing of the education’s initiation, the periods before PD catheter placement or during catheter embedding were more common than 1–6 days after placement in both years. In terms of the duration, 30-min to 1-h education sessions were most common, and the majority of facilities provided guidance for more than 7 days in both years. These results were different from the schedules recommended by the International Society for Peritoneal Dialysis (3 h per session for more than 5 days, initiated 10 days after the operation). Regarding educational content, most facilities provided education on PD procedures and bathing; however, in some facilities, the content did not include dietary guidance, the importance of residual kidney function, medications, laboratory data, troubleshooting, medical security, or social resources. In both years, approximately 70% of the instructional items comprised the PD procedure, exit-site care, bathing, and infection prevention. Regarding education management, the patients’ levels of understanding were evaluated via manual or oral tests in most of the facilities. Regarding the method of demonstration, the entire procedure was explained during the demonstration in almost all institutes. Nurses in > 50% of facilities visited the patients’ homes either when PD was introduced or as needed. The majority of facilities did not use cognitive-function tests when PD was introduced to older adults. Regarding exit-site care and bathing, no consensus existed. Almost half of facilities performed regular, scheduled retraining. Conclusions: In this study, patients’ PD-related educational situations differed from those recommended by the International Society for Peritoneal Dialysis, and no consensus for exit-site care or bathing existed. To improve the clinical level of PD practice in Japan, original Japanese guidelines for patients’ PD education are required, for which our results may serve as the foundation.

  • Effect of administration and withdrawal of the sodium-glucose cotransporter 2 inhibitor, tofogliflozin, on renal protection in individuals with type 2 diabetes mellitus and diabetic nephropathy: A multicenter, single-arm study (RESTORE-nephropathy study)

     概要を見る

    Aims/Introduction: The mechanisms of the renoprotective effects of sodium-glucose cotransporter 2 inhibitors are unknown. This study aimed to explore the effect and mechanism of tofogliflozin on urinary albumin by administration, withdrawal, and re-administration. Materials and Methods: Individuals with type 2 diabetes mellitus and stage 2 or 3 diabetic nephropathy were enrolled. Tofogliflozin was administered for 24 weeks, withdrawn for 12 weeks (withdrawal period), and re-administered for 24 weeks. The primary endpoint was the change in urinary albumin/creatinine ratio (UACR). The secondary endpoints included hemoglobin A1c (HbA1c), hepatic biomarkers, lipid profiles, physical examinations, and blood counts. Results: A total of 47 individuals were enrolled. UACR significantly decreased throughout the observation period. It also significantly decreased, increased, and again decreased during the period of the 1st administration, withdrawal, and re-administration, respectively. HbA1c, body weight, waist circumference, and systolic blood pressure also showed the same tendency. Aspartate aminotransferase and alanine aminotransferase significantly decreased throughout the observation period, but did not increase during the withdrawal period. Conclusions: Urinary albumin improved during the administration of tofogliflozin and worsened during its withdrawal, suggesting the reversibility of its renoprotective effect. The administration of tofogliflozin should be continued to avoid the reversal of glycemic control, renoprotective effects, and other beneficial effects.

     概要を見る

    BACKGROUND: There is limited knowledge regarding effective strategies, including information and communication technology (ICT)-based interventions, to reduce sodium intake and increase potassium intake in healthy individuals. METHODS: We conducted a three-month randomized controlled trial involving healthy adult employees with spot urine sodium-to-potassium ratios (spot UNa/UK) ≥4.0 or estimated 24-hour salt intake ≥10g. Estimated 24-hour UNa and UK were calculated using the Tanaka formula. Participants were assigned to one of four groups: (1) online education, where participants monitored their spot UNa/UK and received feedback from dieticians (n=84); (2) messaging, with similar self-monitoring and dietician messages (n=84); (3) self-learning, provided with an educational leaflet (n=87); and (4) a control group (n=87). The primary outcome was the change in spot UNa/UK ratios, and secondary outcomes included changes in estimated 24-hour UNa and UK. The trial protocol specified a hierarchical order for testing the interventions, anticipating the highest efficacy in the online education group. RESULTS: After the intervention, the online education group showed a decrease in spot UNa/UK ratios (mean -0.9 [95% CI -1.8 to 0.0], p=0.052) compared to the control group. The increase in estimated 24-hour UK excretion was larger in the online education compared to control group (mean +2.5 mmol/day [95% CI -0.3 to 5.3], p=0.085). The difference in estimated 24-hour UNa excretion between the online education and control groups was -4.3 mmol/day (95% CI -15.5 to 6.9, p=0.45). CONCLUSIONS: Combining self-monitoring of sodium and potassium intake with ICT-based interventions, including online nutritional education, was associated with a modest reduction in the estimated ratios of sodium and potassium intake in healthy individuals.

    腎臓は生体の水分・電解質の恒常性維持に重要な役割を果たす。アデノシンは腎機能と腎血流の重要な規定因子として知られているが、アデノシンの腎臓における分布は知られていない。MALDI-IMSは、臓器内の小分子を可視化する新しい手法である。本研究では、MALDI-IMSを用いて、腎臓内の代謝小分子の可視化を試みた。腎臓における多くの代謝小分子は、MALDI-IMSにて半定量的に可視化が可能であった。アデノシンは腎皮髄境界の外側線条に特徴的な集積を呈していた。このことから、血圧変動に応じた髄質血流の調節において、アデノシンが重要な役割を果たす可能性が示唆された。
