摘要

Acute gout can be accompanied by systemic signs of inflammation, with fever, leucocytosis and elevation of high-sensitivity CRP in the blood. Many believe that systemic signs are a reflection of the intense local inflammatory reaction of monocytes and macrophages with urate crystals within the synovium, leading to the release of ILs and other inflammatory cytokines that cause systemic inflammation. In this issue of Rheumatology, Grainger ef al. [1] present a study that reports on patients with hyperuri-caemia who do not experience an episode of gout but who show signs of systemic inflammation. Specifically, they reported that serum monocyte chemoattractant protein-1 (MCP-1) and CD14-positive monocytes were elevated in patients with elevated serum urate levels compared with normouricaemic controls. Moreover, elevation of these parameters was present in patients with a history of acute and chronic gout who did not have a gout attack (intercritical period) as well as in those who have never had gout (asymptomatic hyperuricaemia). The importance of this observation is that it suggests that the presence of elevated serum urate may represent the presence of low-grade systemic inflammation.
