Abstract
Gout is the most common arthritis that affects more than 2% of adults in developed countries. 3% to 4% of gout is chronic refractory gout. Conventional treatments are considered invalid. A new drug, pegloticase is used to treat chronic refractory gout, and there are still many questions about efficacy and safety. We searched PubMed, web of science, and the Cochrane Library. Preprints and references of related literature were also considered. Related efficacy and safety indicators were statistically analyzed by Review Manager 5.4 to conduct meta-analysis. A total of one article and one clinical trial were included. Pegloticase is able to reduce serum uric acid and reduce tender joints, thereby improving joint function. But pegloticase has more adverse events. Pegloticase can be used to treat chronic refractory gout. However, Pegloticase has a higher risk of adverse events. Considering the efficacy and safety, the scope of clinical applications of pegloticase can be further widened in patients in good medical condition.
