ABSTRACT
Abstract Background Gout is a common inflammatory arthritis caused by increased serum uric acid levels. Untreated or insufficiently treated gout can lead to deposition of monosodium urate crystals in joints, cartilage, and kidneys. Although Tongfengding capsules, a Chinese patent medicine, have long been used to treat gout, their effects and safety have not been reviewed systematically. This study evaluated its efficacy and safety for gout in adults. Methods Randomized controlled trials involving Tongfengding capsule for gout in adults were searched from PubMed, EMBASE, Cochrane Central Register of Controlled Trials, CBM, CNKI, and VIP databases, and analyzed using the Cochrane Handbook criteria. The primary outcome measures were the total effective rate. The secondary outcome measures including the blood uric acid (BUA), 24-h urinary total protein (24-h UTP), blood urea nitrogen (BUN), interleukin (IL)-6, IL-8, tumor necrosis factor-alpha (TNF-α) and adverse effects. The risk of bias was evaluated in all included studies. RevMan ver. 5.3.5 and GRADE profiler was used for data analysis and assessing the quality of evidence, respectively. Results Six studies (n = 607 Chinese participants) were included. Tongfengding capsules plus conventional treatment significantly increased the total effective rate (RR 1.21, 95% CI 1.11-1.33), while reducing the BUA (MD − 66.05 μmol/L, 95% CI − 81.26 to − 50.84), 24-h UTP (MD − 0.83 g/24 h, 95% CI − 0.96 to − 0.70), BUN (MD − 0.90 mmol/L, 95% CI − 1.60 to − 0.20), IL-6 (MD − 6.99 ng/L, 95% CI − 13.22 to − 0.75), IL-8 (MD − 12.17 ng/L, 95% CI − 18.07 to − 6.27), TNF-α (MD − 8.50 ng/L, 95% CI − 15.50 to − 1.51), and adverse effects (RR 0.21, 95% CI 0.04-0.95). Conclusion Tongfengding capsules plus conventional treatment is safe and beneficial for adults with gout compared with conventional treatment.
ABSTRACT
Objective To investigate the effects of Tongfengding capsule combined with diclofenac sodium on blood uric acid level, joint swelling and pain in gout patients. Methods 120 cases of gout patients enrolled in our hospital from January 2014 to June 2016 were selected for the study and divided into the control group and the observation group according to the random number table, with 60 cases in each group. The two groups were given anti-infection, low purine diet and other basic treatment, and both treated with sodium bicarbonate tablets and diclofenac sodium. The observation group was given Tongfengding capsule on this basis and the two groups were treated for four weeks. After treatment, gout related factors erythrocyte sedimentation rate (ESR) was observed in the two groups, and TCM symptoms of redness and swelling, pain scores were evaluated and the onset of gout was observed again at six months after treatment. Results The level of UA (463.47±50.28) CB/(μmol?L) in the control group was significantly higher than that in the control group (434.52±51.63) CB/(μmol?L) (P<0.05). The pain and swelling score of the control group were significantly higher than those in the observation group (P<0.05). The recurrence rate in the observation group (5%) was significantly lower than that in the control group (18.33%) (P<0.05). Conclusion Tongfengding capsule combined with diclofenac sodium can effectively relieve joint swelling, pain symptoms of gout patients and reduce blood uric acid levels with significant clinical efficacy.
