Profibrotic growth factors and inflammatory chemokines have been implicated in the pathogenesis of diabetic nephropathy (DN). However, measurement of urinary monocyte chemoattractant protein-1 (MCP-1) and connective tissue growth factor (CCN2) as prognostic markers has not previously been reported, and neither have two such molecules in urine been examined in a single study of DN. In this prospective observational study, 43 adult diabetic patients were studied, 40 were followed up for 6 years. Urinary MCP-1/creatinine ratios were found to be significantly higher in patients with macroalbuminuria (3.3- and 2.1-fold higher (p < 0.01) than normoalbuminuric and microalbuminuric patients, respectively). CCN2 exhibited a pattern different from that of urinary MCPA. Urinary CCN2/creatinine ratios were greatly elevated in both microalbuminuric and macroalbuminuric patients (125- and 74-fold higher than normoalbuminuric patients, respectively, p < 0.01 and p < 0.05, respectively). Further, urinary CCN2, but not MCP-1, correlated with progression of microalbuminuria (R = 0.49, p < 0.05). In contrast, MCP-1, but not CCN2, correlated with the rate of eGFR decline for all patients (R = 0.61, p < 0.0001), reflective of its predictive value in patients with macroalbuminuria, but not for patients with microalbuminuria or normoalbuminuria. In conclusion, increased urinary CCN2 is associated with the early progression of DN, whereas MCPA is associated with later stage disease. (C) 2009 Elsevier Ltd. All rights reserved.
