BACKGROUND: A recognized noninvasive biomarker to improve risk stratification of immunoglobulin A nephropathy (IgAN) patients is scarce. Fractalkine has been shown to play a key role in glomerular disease as chemoattractant, adhesion and even fibrosis factor. The current study assessed the possibility of plasma fractalkine as a novel biomarker in IgAN patients.

METHODS: Plasma fractalkine was measured in 229 patients with renal biopsy consistent IgAN from 2012 to 2014, and clinical, pathological and prognostic relationships were analyzed.

RESULTS: The plasma fractalkine levels in IgAN patients were significantly correlated with the creatinine level and 24-h urine protein by both univariate and multivariate analysis. Mesangial hypercellularity was still significantly correlated with the plasma fractalkine levels even after adjustment for other potential predictor variables by multivariate analysis. In addition, the counts of CD20+ B cells or CD68+ macrophage in renal biopsies of IgAN patients were significantly correlated with the plasma fractalkine levels, but not CD4+ and CD8+ T cells. Finally, we concluded that patients with higher plasma fractalkine levels had higher risk of poor renal outcome compared with those with lower plasma fractalkine levels. No association was observed between the CX3CR1 polymorphisms and clinical parameters including plasma fractalkine levels and prognosis. Recombinant fractalkine induced mesangial cells extracellular matrix synthesis and promoted the migration of microphage cells RAW264.7.

CONCLUSIONS: Plasma fractalkine levels were associated with creatinine level, 24-h urine protein, mesangial hypercellularity pathological damage, the CD68+ macrophage and CD20+ B cell infiltration in renal tissue and renal outcome in IgAN patients. Plasma fractalkine might be a potential prognosis novel predictor in Chinese patients with IgAN.
