Chinese traditional medicine (GuiZhi-ShaoYao-ZhiMu decoction) as an add-on medication to methotrexate for rheumatoid arthritis: a meta-analysis of randomized clinical trials.

ABSTRACT:

Background

GuiZhi-ShaoYao-ZhiMu decoction (GSZD), a traditional Chinese herbal medication, has been frequently used as an add-on medication to methotrexate (MTX) for rheumatoid arthritis (RA) treatment in China. This meta-analysis evaluated the efficacy and safety of adding GSZD to MTX for RA treatment.

Methods

We performed a systematic search of PubMed, Web of Science, EMBASE, and the Cochrane Library (all databases) for English-language studies and WanFang, VIP, and CNKI for Chinese-language studies up to 28 July 2020. Data from selected studies, mainly the response rates and rate of adverse events (AEs), were extracted independently by two authors, and a random-effects model (Mantel-Haenszel method) was used for the meta-analysis.

Results

A total of 14 randomized controlled trials and 1224 patients were included (623 patients in the GSZD?+?MTX group and 601 patients in the MTX group). For efficacy, the meta-analysis found that combining GSZD with MTX increased the effective rate [relative risk (RR)?=?1.24, 95% confidence interval (CI): 1.18-1.30, based on 1069 patients], defined as >30% efficacy, American College of Rheumatology 20, or a decrease of disease activity score 28 >0.6. Adding GSZD reduced the swollen and tender joint counts, the duration of morning stiffness, the levels of C-reactive protein and rheumatoid factor, and erythrocyte sedimentation rate. The adjuvant therapeutic effect of GSZD was independent of the dose of MTX or the combined utilization of other drugs in both groups. For safety, adding GSZD was associated with a lower rate of total AEs (RR?=?0.46, 95% CI: 0.26-0.83, based on 615 patients) and gastrointestinal tract AEs (RR?=?0.46, 95% CI: 0.24-0.88, based on 537 patients).

Conclusion

Combining GSZD with MTX may be a more efficacious and safer strategy for treating RA compared with MTX alone. Further large studies are warranted to investigate the long-term efficacy and safety of adding GSZD to MTX for RA treatment.

Project description:Background and objectivesGuizhi-Shaoyao-Zhimu decoction (GSZD) is often applied to control rheumatoid arthritis (RA), gout, osteoarthritis, etc. In this study, bioinformatic analysis and experimental verification were used to uncover the integral mechanism profile of GSZD against RA.Materials and methodsThe chemical compositions of GSZD were identified by UPLC-QTOF-MS/MS. MH7A cell model was established to screen active compounds in GSZD, and potential targets of these compounds were predicted through online database retrieval. The differential expression genes (DEGs) in synovial tissue of RA patients and normal controls were retrieved from the GEO database. DEGs and the predicated compounds targets were overlapped, and the overlapped genes were subsequently enriched by GO and KEGG analysis. The pathways with significant enrichments were further experimentally verified.ResultsA total of 19 constituents were identified from GSZD, and 11 compounds showed obviously antiproliferative effects on MH7A cells with IC50 < 100 μg/mL. Bioinformatic analysis indicated that IL-1β, IL-6, MAPK8, JAK2, CXCL8, and CASP3 were the main targets of GSZD, and the integral pharmacological mechanisms profile of GSZD might be related to anti-inflammation and proapoptosis. GSZD can promote the loss of mitochondrial membrane potential (MOMP) and induce apoptosis in MH7A cells. Furthermore, in vitro experiments showed GSZD can not only downregulate mRNA expressions of IL-1β (p<0.05), IL-6 (p<0.05), MMPs (p<0.05) and CCL5 (p<0.05) but also inhibit the nuclear transcription of NF-κB. GSZD also reduced the expressions of Bcl-2 (p<0.05), JAK2 (p<0.05), STAT-3 (p<0.05), whereas increase Bax (p<0.05), Caspase-3 (p<0.05) and caspase-9 (p<0.05).ConclusionCollectively, inducing synovial fibroblast apoptosis and inhibiting inflammatory response are two important ways for GSZD to RA, and our study proved bioinformatic analysis combined with experimental verification is a feasible method to explore the drug targets and mechanism of actions of TCMs.

Project description:AimGuizhi-shaoyao-zhimu decoction (GSZ), a traditional Chinese medicine (TCM) herbal formula, has been shown effective in the treatment of diabetic peripheral neuropathy (DPN). In this study, network analysis was performed to decipher the molecular mechanisms of GSZ in the treatment of DPN.MethodsThe chemical components of the 3 herbs forming GSZ, ie, Ramulus Cinnamomi (Guizhi), Paeonia lactiflora (Shaoyao) and Rhizoma Anemarrhenae (Zhimu), were searched in Chinese medicine dictionaries, and their target proteins were identified in PubChem. DPN genes were searched in PubMed gene databases. Ingenuity Pathway Analysis (IPA) was used to build the GSZ pharmacological network and DPN molecular network. The canonical pathways between the two networks were compared to decipher the molecular mechanisms of GSZ in the treatment of DPN.ResultsSixty-one protein targets for Guizhi, 31 targets for Shaoyao, 47 targets for Zhimu, as well as 23 genes related to DPN were identified and uploaded to IPA. The primary functions of the DPN molecular network were inflammatory response, metabolic disease, cellular assembly and organization. As far as the pharmacological network functions were concerned, Guizhi target proteins were involved in neurological disease, inflammatory disease, cellular growth and proliferation, cell signaling, molecular transport, and nucleic acid metabolism, Shaoyao target proteins were related to neurological disease, inflammatory disease, and Zhimu target proteins focused on cell death and survival, cellular movement, immune cell trafficking, DNA replication, recombination and repair, and cell cycle. In the three-herb combination GSZ, several new network functions were revealed, including the inflammatory response, gene expression, connective tissue development and function, endocrine system disorders, and metabolic disease. The canonical pathway comparison showed that Shaoyao focused on IL-12 signaling and production in macrophages, and Zhimu focused on TNFR2 signaling, death receptor signaling, ILK signaling, IL-17A in gastric cells, IL-6 signaling, IL-8 signaling, the role of JAK1, JAK2, and TYK2 in interferon signaling, IL-9 signaling, HMGB1 signaling, NO production and ROS production in macrophages, whereas GSZ focused aryl hydrocarbon receptor signaling and apoptosis signaling in addition to those pathways induced by Guizhi, Shaoyao and Zhimu.ConclusionAlthough each single herb can affect some DPN-related functions and pathways, GSZ exerts more effects on DPN-related functions and pathways. The effects of GSZ on aryl hydrocarbon receptor signaling and apoptosis signaling pathways may be the key components of its total molecular mechanisms.

Project description:Rheumatoid arthritis (RA) is an autoimmune disease characterized by synovitis. Succinate is an inflammatory metabolic signal that exacerbates RA synovitis by activating succinate receptor 1 (SUCNR1) to amplify the release of IL-1β. Thus, inhibition of succinate activation of SUCRN1 could be an effective method to inhibit the inflammation of RA. Baihu Jia Guizhi decoction (BHGZ), which is composed of Gypsum Fibrosum, Anemarrhena asphodeloides Bge., Cinnamomum cassia Presl., Glycyrrhiza uralensis Fisch., and Oryza sativa L., is a Traditional Chinese Medicine (TCM) prescription used to treat RA in clinic. In addition, TCM believes that damp and heat environment is one of the causes of RA. In this study, we tested the role of damp and heat environments in exacerbating RA inflammation and the anti-inflammatory effect of BHGZ, based on succinate/SUCNR1/IL-1β pathway in the adjuvant arthritis (AA) model with damp and heat environment (AA + DHE). Results showed that paw swelling and synovial pathology were significantly increased in AA rats, and these results were aggravated by stimulation in damp and heat environment. BHGZ improved AA + DHE rats' paw swelling, synovial hyperplasia, and inflammatory cell infiltration and reduced IL-1β. In addition, AA rats significantly increased the expression of SUCNR1, and the stimulation of damp and heat environment not only increased the expression of SUCNR1 but also promoted the accumulation of succinate. BHGZ simultaneously reduced the concentration of succinate and the expression of SUCNR1. Finally, SDH activity was decreased in AA rats and AA + DHE rats, while BHGZ increased SDH activity and then reduced succinate concentration. Therefore, we prove that damp and heat environment deteriorated the inflammation of RA which is the activation of succinate/SUCNR1 pathway, while BHGZ regulates SDH activity to reduce the accumulation of succinate and inhibit the activation of SUCNR1 that is the underlying mechanism of its treatment of RA.

Project description:BackgroundBiqi capsule is a traditional Chinese medicine widely used as a complementary and alternative treatment for rheumatoid arthritis (RA). The objective is to understand the efficacy, safety and mechanism of Biqi combined with methotrexate (MTX) in RA.MethodsWe present a randomized, controlled pilot trial on Biqi combined with MTX against patients with active RA. Seventy patients were randomized 1:1 to receive Biqi + MTX or Leflunomide (LEF) + MTX for 24 weeks, and were assessed at baseline, 4, 12 and 24 weeks. Serum and urine samples were collected for metabolomics.ResultsOverall, 81.2% patients in Biqi group achieved ACR20 at 24 weeks. No statistically significant differences were observed in primary or secondary outcomes between the two groups. A better safety profile was observed for Biqi with significantly fewer adverse effects reported (11.4%) compared to LEF group (40%, P < 0.05). Comparison between treatment responders and non-responders indicated a unique urine metabolic profile of enriched fatty acids and decreased acylcarnitines associated with Biqi responders, indicating a restored energy homeostasis in response to Biqi. The gene targets of these metabolites were significantly enriched in interleukin-4 and interleukin-13 pathways, implying that Biqi could ameliorate Th2-derived inflammatory response. Multivariate network analysis indicated that patient morning stiffness and SJC were key factors associated with metabolomics in Biqi-treated patients, whereas CRP was the main factor in LEF group. Therefore, Biqi and LEF likely work by influencing different patient clinical parameters.ConclusionsOur study suggests that Biqi capsule can be a promising alternative option in combination with MTX for RA treatment, and demonstrates the capability of using metabolomics to interrogate mechanism of action for traditional Chinese medicine.Trial registration This trial is registered with ChiCTR, No. ChiCTR-IPR-16009029.

Project description:BACKGROUND:Rheumatoid arthritis has the characteristics of slow progression, long course, and repeated attacks. At present, western medicine commonly used in clinical practice not only reduces pain and improves symptoms, but also has more adverse reactions, affecting the health, and life of patients. In ancient China, Huangqi Guizhi Wuwu decoction was used by doctors to treat rheumatoid arthritis, with remarkable effect. In recent years, many clinical studies have also shown that Huangqi Guizhi Wuwu decoction has reliable effect in treating rheumatoid arthritis, but there is no evidence of evidence-based medicine. Therefore, this study aims to systematically evaluate the clinical efficacy and safety of Huangqi Guizhi Wuwu decoction in the treatment of rheumatoid arthritis. METHODS:Using computer to retrieve PubMed, The Cochrance Library, Embase, Web of Science, CNKI, VIP and Wanfang database, in addition manually retrieve Google academic and Baidu academic to collect all randomized controlled trials for Huangqi Guizhi Wuwu decoction in the treatment of rheumatoid arthritis, including relevant academic journal and conference papers, dissertations, from the establishment of the database to July 2020. After 2 evaluators independently screened the literature, extracted the data, and evaluated the risk of bias included in the study, RevMan5.3 software was used to analyze the data.

Project description:BackgroundRheumatoid arthritis (RA) is a chronic autoimmune disease characterized by swelling and painful joints, eventually leading to joint destruction. There is still a lack of effective therapy to treat RA. The Juanbi pill is a Chinese medicine that has been widely used to treat active RA in China for hundreds of years, relieving pain and protecting the affected joints from malformation. However, there is no solid evidence to show the effect of the Juanbi pill on the management of active RA.Methods/designWe will conduct a multicenter, randomized, double-blind, placebo-controlled clinical trial to determine whether the traditional Chinese medicine Juanbi pill could relieve joint pain in RA and protect the joints. A total of 120 patients with active RA will be enrolled and treated with the Juanbi pill or a placebo for 3 months. The primary outcome measures are as follows: rate of in the American College of Rheumatology (ACR)50, change in the 28-joint Disease Activity Score (DAS28) from baseline at beginning of therapy to 3 months, and a change in the van der Heijde modified Sharp score measured from baseline to 12 months. The secondary outcome measures are as follows: rate of change in ACR20, ACR70, Health Assessment Questionnaire-Disability Index (HAQ-DI), and change in score in the Patient Assessment of Arthritis Pain, Patient Global Assessment of Arthritis, and the Athens Insomnia Scale (AIS) from baseline to 2-week, 1-month, 2-month, 3-month, 6-month, and 12-month follow up. In addition, the rate of change (score) in the ACR50 and DAS28 from the baseline to 2-week, 1-month, 2-month, 6-month, and 12-month follow up are also the secondary outcome measures.DiscussionAlthough the Juanbi pill has been used in China for many years to treat RA, there is a lack of consensus about its effectiveness. This trial will provide convincing evidence about the effect of Juanbi pill on active RA.Trial registrationClinicalTrials.gov, NCT02885597 . Registered on 30 August 2016.
