Background The prevalence rates of gout worldwide have increased annually. Acute gouty arthritis (AGA) accounts for a large proportion of gout patients and causes severe physical and mental pain in patients. Controlling the occurrence and development of gout inflammation is the first step in the treatment of gout. The main treatment drugs in gout are Non-Steroid Anti-Inflammatory Drugs (NSAIDS), colchicine and glucocorticoids, but these treatments have many adverse reactions which limit their clinical application. Baihu and Guizhi decoction (BHGZ) is one of the classic prescriptions in the Synopsis of the Golden Chamber, and is a good prescription for AGA. Previous clinical studies have shown that BHGZ confers a strong benefit for treating AGA. However, the literature shows a lack of high-quality RCT research on BHGZ with respect to AGA. Therefore, in this study, we use a randomized, double-blind, controlled study with a placebo to evaluate the clinical efficacy and safety of BHGZ on the AGA of moist heat arthralgia spasm syndrome. Methods This study is a randomized, double-blind, controlled clinical trial. A total of 102 adult participants with AGA of moist heat arthralgia spasm syndrome will be enrolled, with balanced treatment allocation (1:1). The experimental intervention will be BHGZ plus the low-dose colchicine and the control intervention will be placebo plus the low-dose colchicine for 10 days. To study the clinical efficacy (including VAS score; joint tenderness, joint swelling, joint movement disorder; TCM evidence efficacy score) and the changes of inflammatory indexes. At the same time, the improvement of joint inflammation in patients with AGA will be observed from musculoskeletal ultrasound imaging, and the safety evaluation will be carried out. Discussion This study will be the first placebo-controlled RCT to assess whether BHGZ plus low-dose colchicine have beneficial effects on changing reducing inflammation of joints for patients with AGA of moist heat arthralgia spasm syndrome. The results of this trial will help to provide evidence-based recommendations for clinicians. Trial registration: Chinese Clinical Trials Register, ChiCTR1900024974. Registered on 5 August 2019.
Background Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease with the primary clinical symptoms of joint swelling and pain. Early detection of erosion and synovial inflammation at an active stage resulting from RA can prevent damage to the joints and activity restriction. However, there are still many patients who do not respond to these treatments; the development of newer, safer drugs is urgently needed. Compared to Western medicine, Guizhi-Shaoyao-Zhimu decoction has equal or higher efficacy and safety for RA patients. With the widespread use of musculoskeletal ultrasound (MSUS), this technology holds great value for the degree of joint damage in RA patients, guiding the clinical selection of treatments, and assessing of prognosis. Therefore, we designed a double-blinded randomized controlled clinical trial to measure the safety and efficacy of Guizhi-Shaoyao-Zhimu decoction in treating early-stage RA using MSUS. Methods This study is a randomized, double-blinded, parallel group, placebo-controlled trial. A total of 152 adult participants with early RA will be enrolled, with balanced treatment allocation (1:1). The experimental intervention will be Guizhi-Shaoyao-Zhimu decoction plus the conventional medicine methotrexate and the control intervention will be placebo plus the conventional drug methotrexate for 3 months. In addition, both groups will receive folic acid during treatment to prevent side effects from methotrexate. The primary outcomes are the erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), hepatic and renal function, visual analog scale, disease activity score in 28 joints, measurement scale for TCM symptoms, and 7-joint ultrasound score. Discussion We designed this double-blinded randomized controlled clinical trial to evaluate the efficacy and safety of Guizhi-Shaoyao-Zhimu decoction in RA patients using MSUS. The results of this trial may provide insights into how to improve the clinical symptoms of RA patients and delay further joint destruction. We hope that this trial may provide preliminary evidence of the efficacy of Guizhi-Shaoyao-Zhimu decoction in treating RA patients and that these results aid researchers, practitioners, and patients alike. Aim The main aim of the study is to clarify the efficacy and safety of Guizhi-Shaoyao-Zhimu decoction in patients with early RA. Trial registration Chinese Clinical Trials Register ChiCTR2000036141.
