简要总结
This study is a prospective randomized controlled trial, enrolling 70 patients with CKD stages 2-4, randomly divided into a control group and a treatment group, with 35 cases in each group. The study subjects are sourced from three centers. The control group receives integrated basic treatment for chronic kidney disease, including dietary nutrition adjustment, blood pressure control, blood sugar control, lipid control, anemia treatment, and regulation of water, electrolyte, and acid-base metabolic balance. The treatment group, in addition to the basic treatment, is administered Nephropathy Formula No. 1 orally, with a treatment course of 12 weeks and a follow-up period of 2 weeks. The outcome measures are the changes in biochemical indicators, inflammatory factors, T cell subsets, STAT3 mRNA expression, and TCM syndrome scores after 12 weeks of treatment, to assess therapeutic efficacy. This study proposes the experimental hypothesis that Nephropathy Formula No. 1 can effectively improve the T cell immune balance in CKD patients by modulating the IL-6/STAT3 signaling pathway, thereby inhibiting the occurrence and development of renal fibrosis and improving the prognosis of CKD to a certain extent. Specifically, Nephropathy Formula No. 1 may function through the following mechanisms: (1) downregulating IL-6 mRNA expression, reducing IL-6 secretion, and thereby inhibiting the activation of the STAT3 signaling pathway; (2) regulating the balance of Th17/Treg cell subsets, promoting the differentiation of Th17 cells into Treg cells, enhancing the anti-inflammatory and immunosuppressive effects of Treg cells, and alleviating renal inflammatory responses and fibrosis. Through in-depth exploration of this study, it is expected to provide new ideas and methods for the clinical treatment of CKD, with significant scientific and clinical implications.
详细描述
Sample Size Estimation Sample size estimation is based on the results of a pilot study. A total of 60 patients are required for enrollment. Considering a dropout rate of 10%-15%, each group will need 35 cases, with a total of 70 cases for both groups.
Patient Recruitment Patients will be recruited by researchers during outpatient or inpatient visits. After screening according to the inclusion and exclusion criteria, eligible patients will be enrolled in the study following the signing of the informed consent form.
Adverse Events and Serious Adverse Events Management Severity: Physicians can use the following definitions to judge the severity of all adverse events and serious adverse events, which will serve as endpoints/data cutoff points for the study.
Mild: Adverse events are transient and easily tolerated by the patient. Moderate: Adverse events cause discomfort to the subject and interfere with their normal activities.
Severe: Adverse events significantly impact the subject's daily activities and may result in functional loss or be life-threatening.
