Clinical trial for conventional medicine integrated with traditional Chinese medicine (TCM) in the treatment of patients with chronic kidney disease

Background: The prevalence of chronic kidney disease (CKD) has been rapidly increasing and has become one of the most concerned global health problems. It is of good importance to improve therapeutic efficiency of CKD and delay disease progression to end stage renal disease (ESRD). Traditional Chinese Medicine (TCM) is a widely used complementary therapy for patients with CKD. The aim of this study is to evaluate whether basic treatment combined with Chinese herbs mixture Qi Gui Yi Shen decoction could achieve better therapeutic effect on CKD patients. Methods: To determine whether traditional Chinese medicine Qi Gui Yi Shen decoction could achieve better therapeutic effect, we will conduct a randomized controlled trial. A total of 100 CKD patients that meet the inclusion criteria will be enrolled and divided into 2 groups: Qi Gui Yi Shen group (QGYS group) and placebo group. Each group will receive 6-monthly basic treatment in combination with TCM or placebo 3 times per day. Efficacy of Qi Gui Yi Shen decoction is evaluated by analyzing renal function and TCM symptoms, other efficacy assessments include serum level of PAI-I, expression of transforming growth factor beta1 (TGF-beta1). Routine blood count, plasma albumin (ALB), and alanine transaminase (ALT) are evaluated as side effect and safety profile. Discussion: The results from the clinical trial will provide evidence for the effectiveness and safety of Qi Gui Yi Shen Decoction as a treatment for CKD patients. Furthermore, this will propose a new theory and method for CKD treatment.
