We investigate the role of homeostatic mechanisms involved in acute, postprandial nutrient metabolism and nutrient-induced systemic inflammation in CKD presence and progression in Metabolic dysfunction-associated steatohepatitis (MASH). We assessed postprandial incretins (GLP-1 and GIP), intestinotropic hormone GLP-2, endotoxin LPS, Zonulin (a marker of intestinal permeability), hepatokines, adipokines and NF-kB activation in circulating MNCs during a meal tolerance test in 52 biopsy proven MASH patients randomized to curcumin Meriva or placebo and 26 matched controls. At baseline, MASH-CKD had a lower GLP-2 response and a 2-fold higher postprandial LPS and NF-kB activation in MNCs than MASH patients without CKD, but similar remaining postprandial or fasting parameters. Postprandial IAUC GLP-2 predicted the presence of CKD in MASH (OR = 0.43, 95%CI:0.32-0.80, p = 0.008) independently of liver histology and traditional risk factors. After 72 weeks, changes in IAUC GLP-2 independently predicted the presence of CKD (OR = 0.49, 95%CI:0.21-0.73, p = 0.010) and eGFR changes [β(SE) = 0.510(0.007, p = 0.006] at end-of-treatment, In MASH, an impaired GLP-2 response to meals is associated with intestinal barrier dysfunction, endotoxemia and NF-kB-mediated systemic inflammation and may promote renal dysfunction and CKD. These data provide the rationale for evaluating GLP-2 analogues in MASH-related CKD.

餐后 GLP-2 反应受损会增强代谢功能障碍相关脂肪性肝炎 (MASH) 中的内毒素血症、全身炎症和肾损伤:磷脂姜黄素 meriva 的影响。



我们研究了参与急性餐后营养代谢和营养诱导的全身炎症的稳态机制在代谢功能障碍相关脂肪性肝炎 (MASH) 的 CKD 存在和进展中的作用。我们在 52 名经活检证实的 MASH 患者和26 名匹配的对照中,评估了餐后肠促胰岛素 (GLP-1 和 GIP)、促肠道激素 GLP-2、内毒素 LPS、Zonulin(肠道通透性的标志物)、肝因子、脂肪因子和 NF-kB 活化。在基线时,MASH-CKD 在 MNC 中的 GLP-2 反应较低,餐后 LPS 和 NF-kB 激活比无 CKD 的 MASH 患者高 2 倍,但剩余的餐后或空腹参数相似。餐后 IAUC GLP-2 预测了 MASH 中 CKD 的存在 (OR = 0.43,95%CI:0.32-0.80,p = 0.008),独立于肝脏组织学和传统危险因素。72 周后,IAUC GLP-2 的变化独立预测 CKD 的存在 (OR = 0.49,95%CI:0.21-0.73,p = 0.010) 和 eGFR 变化 [β(SE) = 0.510(0.007,p = 0.006] 在治疗结束时,在 MASH 中,GLP-2 对膳食的反应受损与肠道屏障功能障碍、内毒素血症和 NF-kB 介导的全身炎症有关,并可能促进肾功能障碍和 CKD。这些数据为评估 MASH 相关 CKD 中的 GLP-2 类似物提供了基本原理。
