Traditional Chinese medicine therapy for rheumatoid arthritis: a review / 中国中药杂志

Rheumatoid arthritis(RA) is an autoimmune disease that seriously affects the physical and mental health of patients, but its pathogenesis is still unclear. At present, clinical treatment drugs include conventional synthetic disease modifing anti-rheumatic drugs(csDMARDs), nonsteroid anti-inflammtory drugs(NSAIDs), hormones, small molecule targeted drugs, biological agents, etc. These drugs can relieve the clinical symptoms of most patients with RA to a certain extent, but there are still many limitations, such as drug adverse reactions and individual differences in drug efficacy. Therefore, the research on drug treatment targets and the development of low-toxicity drugs helps further improve the precise prevention, diagnosis, and treatment of RA. There is an urgent need for efficient and low-toxic treatments to delay the clinical progress of RA. As a treasure of Chinese culture, traditional Chinese medicine(TCM) is widely used as an alternative therapy in the treatment of various diseases, and has a significant clinical efficacy. TCM therapy(including monomer traditional Chinese medicine, classical compounds, and non-drug therapies) has a significant curative effect on RA. Based on the literature research in recent years, this paper reviewed the clinical and mechanism research of TCM therapy in the treatment of RA, and provided more in-depth thinking for the wide application of TCM therapy in clinical practice.

Network Meta-analysis of efficacy and safety of Chinese patent medicines in treatment of ankylosing spondylitis / 中国中药杂志

To evaluate the efficacy and safety of Chinese patent medicines in the treatment of ankylosing spondylitis(AS) by frequency network Meta-analysis. Randomized controlled trials(RCTs)of Chinese patent medicines for AS were retrieved from CNKI, Wanfang, VIP, CBM, PubMed, EMbase and Cochrane Library databases from the time of database establishment to January 2021. The quality of the included RCTs was evaluated according to the Cochrane bias risk standard, and the data was analyzed by RevMan 5.3 and Stata/MP 15.1. A total of 12 kinds of Chinese patent medicines in 55 RCTs were included. According to Meta-analysis, in term of the effectiveness, the top three optimal medication regimens were Biqi Capsules, Yishen Juanbi Pills and Yaobitong Capsules combined with western medicine. The top three interventions to reduce the erythrocyte sedimentation rate(ESR)were Yishen Juanbi Pills, Xianling Gubao Capsules and Fufang Xuanju Capsules combined with western medicine. The top three interventions to reduce the C-reactive protein(CRP)were Biqi Capsules, Xianling Gubao Capsules and Fufang Xuanju Capsules combined with western medicine. In terms of the safety, top three optimal medication regimens were Total Glucosides of Paeony Capsules, Yishen Juanbi Pills, and Wangbi Tablets combined with western medicine. This network Meta-analysis suggests that Chinese patent medicines combined with conventional western medicine can effectively improve the joint pain symptoms of AS patients and reduce the acute inflammatory indicators, with high safety. However, the literature included in this study is generally of low methodological quality, and the conclusion needs to be verified by high-quality research.

A double-blind, double-dummy, randomized controlled, multicenter trial of 99Tc-methylene diphosphonate in patients with moderate to severe rheumatoid arthritis / 中华医学杂志(英文版)

BACKGROUND@#Clinical observational studies revealed that 99Tc-methylene diphosphonate (99Tc-MDP) could reduce joint pain and swollenness in rheumatoid arthritis (RA) patients. This multicenter, randomized, double-blind, double-dummy study aimed to evaluate the effects of 99Tc-MDP plus methotrexate (MTX) vs. MTX alone or 99Tc-MDP alone on disease activity and structural damage in MTX-naïve Chinese patients with moderate to severe RA.@*METHODS@#Eligible patients with moderate to severely active RA were randomized to receive 99Tc-MDP plus MTX (n = 59) vs. MTX (n = 59) alone or 99Tc-MDP (n = 59) alone for 48 weeks from six study sites across four provinces in China. The primary outcomes were the American College of Rheumatology 20% improvement (ACR20) response rates at week 24 and changes in modified total Sharp score at week 48.@*RESULTS@#At week 24, the proportion of participants achieving ACR20 was significantly higher in the MTX + 99Tc-MDP combination group (69.5%) than that in the MTX group (50.8%) or 99Tc-MDP group (47.5%) (P = 0.03 for MTX + 99Tc-MDP vs. MTX, and MTX + 99Tc-MDP vs.99Tc-MDP, respectively). The participants in the MTX + 99Tc-MDP group and the 99Tc-MDP group had significantly less important radiographic progression than the participants in the MTX group over the 48 weeks (MTX + 99Tc-MDP vs. MTX: P = 0.03, 99Tc-MDP vs. MTX: P = 0.03, respectively). There was no significant difference in terms of adverse events (AEs) among the groups. No serious AEs were observed.@*CONCLUSIONS@#This study demonstrated that the combination of 99Tc-MDP with MTX inhibited structural damage and improved disease activity in RA patients compared with MTX and 99Tc-MDP monotherapies, without increasing the rate of AEs. Additional clinical studies of 99Tc-MDP therapy in patients with RA are warranted.@*TRIAL REGISTRATION@#Chictr.org, ChiCTR-IPR-14005684; http://www.chictr.org.cn/showproj.aspx?proj=10088.

Anti-cyclic citrullinated peptide antibody predicts the development of rheumatoid arthritis in patients with undifferentiated arthritis / 中华医学杂志(英文版)

BACKGROUND@#Clinical outcomes of undifferentiated arthritis (UA) are diverse, and only 40% of patients with UA develop rheumatoid arthritis (RA) after 3 years. Discovering predictive markers at disease onset for further intervention is critical. Therefore, our objective was to analyze the clinical outcomes of UA and ascertain the predictors for RA development.@*METHODS@#We performed a prospective, multi-center study from January 2013 to October 2016 among Chinese patients diagnosed with UA in 22 tertiary-care hospitals. Clinical and serological parameters were obtained at recruitment. Follow-up was undertaken in all patients every 12 weeks for 2 years. Predictive factors of disease progression were identified using multivariate Cox proportional hazards regression.@*RESULTS@#A total of 234 patients were recruited in this study, and 17 (7.3%) patients failed to follow up during the study. Among the 217 patients who completed the study, 83 (38.2%) patients went into remission. UA patients who developed RA had a higher rheumatoid factor (RF)-positivity (42.9% vs. 16.8%, χ = 8.228, P = 0.008), anti-cyclic citrullinated peptide (CCP) antibody-positivity (66.7% vs. 10.7%, χ = 43.897, P < 0.001), and double-positivity rate of RF and anti-CCP antibody (38.1% vs. 4.1%, χ = 32.131, P < 0.001) than those who did not. Anti-CCP antibody but not RF was an independent predictor for RA development (hazard ratio 18.017, 95% confidence interval: 5.803-55.938; P < 0.001).@*CONCLUSION@#As an independent predictor of RA, anti-CCP antibody should be tested at disease onset in all patients with UA.

Effect of icariin on bone destruction and serum RANKL/OPG levels in type II collagen-induced arthritis rats / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the effect of Icariin (ICA) on serum receptor activator of NFkappaB-ligand (RANKL)/osteoprotegerin (OPG) production and bone destruction in type II collagen-induced arthritis (CIA) rats.</p><p><b>METHODS</b>The CIA rat model was established in all rats, except those in the normal group (n = 8) using bovine type II collagen and complete Freund's adjuvant. Totally 24 CIA rats with arthritis index (AI) > or = 6 were selected and divided into the model group, the methotrexate (MTX) group, and the ICA group according to the AI score, 8 in each group. Normal saline was given to rats in the normal group and the model group by gastrogavage. MTX at the weekly dose of 5 mg/kg was given to rats in the MTX group. ICA at the daily dose of 20 mg/kg was given to rats in the ICA group. All medication lasted for 4 weeks. The AI scores were recorded once a week. Histomorphologic changes of the ankle joint were observed by HE staining. The bone destruction and the osteoporosis of the foot phalanx were detected by X-ray. Serum levels of RANKL and OPG were determined by enzyme-linked immunosorbent assay (ELISA).</p><p><b>RESULTS</b>After 4-week intervention, when compared with the model group, AI score and Larsen score were significantly lower, the serum RANKL concentration and the RANKL/OPG ratio obviously decreased, while the serum OPG concentration obviously increased in the CIA group (P < 0.05, P < 0.01). In the MTX group, the aforesaid indices decreased, but without statistical difference (P > 0.05). Results of HE staining indicated that hyperplasia of joint synovium, infiltration of inflammatory cells, and the degree of articular cartilage destruction were obviously alleviated in the ICA group.</p><p><b>CONCLUSION</b>ICA could alleviate or lessen the degree of articular cartilage destruction in CIA rats, and its mechanism might be associated with reducing serum levels of RANKL and elevating levels of OPG, thus further decreasing the ratio of RANKL/OPG.</p>
