Oral proprietary Chinese medicine for lupus nephritis: A bayesian network meta-analysis

To analyze the efficacy and safety of proprietary Chinese medicines for the treatment of Lupus Nephritis (LN) based on the reticulated meta analysis. The study aim to provide evidence-based evidence for the clinical treatment of LN.

The studies related to the randomized controlled studies (RCTs) on the treatment of LN with oral proprietary Chinese medicines were obtained from China National Knowledge Infrastructure (CNKI), Database for Chinese Technical Periodicals (VIP), SinoMed, Wanfang, PubMed, Web of Science, Embase and Cochrane Library databases since its inception-August 2022. Cochrane tools were used for risk bias assessment, Stata 13.0 and ADDIS 1.16.5 software were used for net evidence analysis.Results.1) 41 RCTs with 3124 L N patients were included, involving 9 types of proprietary Chinese medicines.2) The meta-analysis showed that in terms of efficacy, the top 3 Chinese patent medicine interventions were Xin Gan Bao Capsule (XGB) +western medicines (WM), Huang Kui Capsule (HK) + WM, Kun Xian Capsule (KX) + WM; in terms of reducing adverse event rate, the top 3 Chinese patent medicine interventions were Yi Shen Hua Shi Granules (YSHS) + WM, Jin Shui Bao Capsule (JSB) + WM, HK + WM; in terms of reducing 24 h urine protein, the top 3 Chinese patent medicine interventions were XGB + WM, YSHS + WM, Bai Ling Capsule (BL) + WM; in terms of reducing blood creatinine (Cr), the top 3 Chinese patent medicine interventions were Yi Shen Granules (YS) + WM, JSB + WM, KX + WM; in terms of reducing urea nitrogen (BUN), the top 3 Chinese patent medicine interventions were Shen Kang Capsule (SK) + WM, HK + WM, JSB + WM; in terms of reducing systemic lupus erythematosus disease activity index (SLEDAI) scores, the top 3 Chinese patent medicine interventions were JSB + WM, BL + WM, YSHS + WM; in terms of improving complement C3, the top 3 Chinese patent medicine interventions were HK + WM, XGB + WM, BL + WM; in terms of improving complement C4, the top 3 Chinese patent medicine interventions were KX + WM, YSHS + WM, BL + WM.

Xin Gan Bao Capsule has a good efficacy in improving efficiency and the level of complement C3, lowering 24 h urine protein. Jin Shui Bao Capsule and Huang Kui Capsule have a good efficacy in treating LN. However, more multicentre, large sample and high quality RCTs are needed for validation the results.
