The Effect and Mechanism of Xiqing Regulating Intestinal Homeostasis on Drug Efficacy of Chronic Kidney Disease

Recruiting now · Phase 4

Conditions studied: CKD, Drug Effect

In brief

Chronic kidney disease (CKD) has become a major public health problem worldwide. Patients with CKD are often accompanied by azotemia due to impaired renal function and excretion of nitrogen metabolic waste, which leads to multiple organ dysfunction, cardiac dysfunction and other complications. Therefore, it is an important strategy in the treatment of CKD to reduce the burden of kidney in CKD patients by removing nitrogen metabolic wastes in the body. Xiqing, which includes coated aldehyde oxystarch capsules, is a drug with adsorption effect. As an effective nitrogen metabolic waste adsorbent, it is widely used in the treatment of CKD patients. Gut is an important organ for the generation of nitrogen metabolic waste in the body. Intestinal homeostasis is an important regulator of nitrogen metabolism, and supplementation of probiotics is one of the main ways to regulate intestinal homeostasis. A study published by the team of investigators in the journal Cell Metabolism in 2021 confirmed that probiotics (Lactobacillus casei Zhang) reduced the BUN level in CKD mice, intestinal inflammation and the permeability of intestinal mucosal barrier, and delay the progression of CKD patients through animal experiments and clinical trials. So, whether the application of Xiqing changes intestinal homeostasis, including intestinal flora structure, function and function of intestinal mucosa, intestinal metabolites? Whether drug effect is affected by intestinal balance of CKD? What is the mechanism? Is Xiqing combined with probiotics more conducive to reducing BUN level and delaying the progression of CKD patients? The discussion of the problem and solution will help clinicians for the pioneering understanding of the use of Xiqing. In this study, the investigators designed a prospective, randomized, open-label, blinded end-point clinical trial, using microbial diversity, metagenomics, targeted and non-targeted metabolomics detection and other technologies, through the joint analysis of multi-omics data, to explore the effect of the use of Xiqing on the intestinal homeostasis of CKD, and the extent of the drug efficacy of Xiqing is affected by the intestinal homeostasis of CKD. The effect of Xiqing combined the probiotics regulating intestinal homeostasis on CKD and the molecular mechanism, which provide more research references for the clinical application of Xiqing.
