OBJECTIVES: Soluble C-X-C chemokine ligand 16 (CXCL16) was shown to recruit polymorphonuclear cells into synovial tissue in gout patients. The aim of this study was to explore the pathophysiological characteristics of CXCL16 in gout patients with or without chronic kidney disease (CKD). DESIGN AND METHODS: 42 gout patients, 22 CKD and 20 healthy subjects were enrolled. Plasma CXCL16 and other biochemical parameters were tested. RESULTS: Plasma CXCL16 levels in gout subjects with CKD were significantly increased compared with healthy, CKD and gout subjects without CKD. Soluble CXCL16 levels in gout subjects were closely correlated with renal function and lipid profiles, and independently associated with 24h proteinuria, creatinine clearance rate and C-reactive protein. CONCLUSION: Our data indicated that plasma CXCL16 levels are significantly increased in gout patients with and without CKD, and are independently associated with renal function. Elucidating the pathophysiologcial role of CXCL16 in gout patients requires further study.
