We investigated these polymorphisms in IgA nephropathy (IgAN) patients undergoing hemodialysis (HD) and their significance on progression to end-stage renal failure (ESRF). Methods: To evaluate the role of polymorphisms in genes described below, we analyzed the association of these polymorphisms with progression to ESRF in histologically-proven IgAN patients undergoing HD using Kaplan-Meier method. Employed genes are angiotensin-converting enzyme, angiotensinogen, monocyte chemoattractant protein-1, chemokine receptor (CCR5), transforming growth factor-β1, E-selectin (SELE), and L-selectin (SELL). Results: The duration between renal biopsy and ESRF (induction to HD) was significantly shorter in IgAN patients with T1402 allele at the SELE gene, G(-642) allele or T712 allele at the SELL gene than those without them. Any other polymorphisms were not significantly associated with progression to ESRF in this study. Conclusion: This work provides evidence that the T1402C polymorphism of the SELE gene, A(-642)G and C712T polymorphisms of the SELL gene are associated with rapid progression to ESRF in IgAN patients. Keywords: IgA nephropathy, end-stage renal failure, polymorphism, E-/L-selectin J Saitama Med School 2004;31:55-66 (Received December 9, 2003)
