Xiao Zheng San Jie Granules in the Treatment of Qi Deficiency and Blood Stasis Syndrome in Patients With Diabetic Kidney Disease Stage IV: Protocol for a Randomised, Double-blind, Placebo-controlled, Multi-centre Trial
crossref(2021)
Abstract
Abstract Introduction Diabetic kidney disease (DKD) is a major microvascular complication of diabetes mellitus (DM) and the primary cause of end-stage renal disease. Routine medication might result in adverse effects which limit their usage. Laboratory studies have shown that Xiao Zheng San Jie (XZSJ) granules is effective in reducing the levels of urinary protein and blood creatinine in rats with DKD. Hence, we aim to conduct a clinical trial to determine the efficacy and safety of XZSJ granules among patients with DKD Stage IV, who present with the syndromes of qi deficiency and blood stasis. The purpose of this paper is to report the methodology of this trial.Methods and analysisThis is a randomised, double-blind, placebo-controlled, multi-centre clinical trial. A total of 72 patients with DKD Stage IV who have the syndromes of qi deficiency and blood stasis will be randomly assigned to either intervention or placebo group. In addition to routine medication, the intervention group will be given XZSJ formula (in granules) and the control group will be given placebo for 12-weeks. Data collected at baseline as well as weeks 4, 8 and 12 will be recorded in case report forms and subsequently entered into EpiData 3.1 electronic database. Adverse events will also be documented. Primary outcomes – estimated glomerular filtration rate, urinary albumin-to-creatinine ratio, and serum creatinine – will be assessed after 12 weeks. Ethics and disseminationThis trial has been approved by the Research Ethics Committee of Dongzhimen Hospital (DZMEC-KY-2018-60). Informed consent will be obtained from all participants. Results of this study will be disseminated to the public through academic conferences and peer-reviewed journals.DiscussionThis trial might provide information on an effective method for the treatment of DKD, especially for patients who present with the syndromes of qi deficiency and blood stasis. We hope that this trial will serve as a reference for the conception of high-quality Traditional Chinese Medicine trials in the future, which incorporate syndrome diagnosis into the study design.Trial registration Chinese Clinical Trial Registry, ChiCTR1900021391.
