Effect of external use of Qingluo San on clinical efficacy in patients with acute gouty arthritis

OBJECTIVE: The present study aimed to observe the clinical efficacy of the external use of Qingluo San combined with diclofenac sodium double-release enteric capsules in the treatment of acute gouty arthritis (dampness–heat accumulation syndrome). METHODS: A total of 58 acute gouty arthritis patients were divided into two groups using the random number table method. Diclofenac sodium double-release enteric capsules were orally administered in the control group. Based on the treatment in the control group, the external use of Qingluo San was given in the treatment group, with 7-day course of treatment. The changes in visual analog scale (VAS) scores, the tenderness, swelling, and mobility function of the joint, and the traditional Chinese medicine (TCM) syndrome scores before and after the treatment, at day 0, 1, 3, 5 and 7, were observed in both groups, together with the comparison of laboratory indicators (erythrocyte sedimentation rate, ESR; C-reactive protein, CRP; uric acid, UA). RESULTS: The total effective rate was 96.55% in the treatment group and 82.76% in the control group. After treatment, the VAS score, the tenderness, swelling and function scores of the joint, and the TCM syndrome scores decreased in both groups. The treatment group was superior in improving the VAS scores, the tenderness, swelling and mobility function of the joint, and TCM syndrome scores, when compared to the control group (p < 0.05). The laboratory indicators, which included the ESR, CRP and UA, obviously decreased in both groups after treatment (p < 0.05). The ESR significantly decreased in the treatment group, when compared to the control group (p < 0.05). CONCLUSION: The combination of the external use of Qingluo San and oral administration of diclofenac sodium double-release enteric capsules can more rapidly relieve joint pain, and improve the clinical efficacy. This combination therapy also has certain advantages in relieving joint swelling and improving the mobility function of the joint. Hence, this is worthy of clinical promotion and application.
