Abstract: Chronic kidney disease (CKD) is characterized by accumulation of proinflammatory cytokines, mainly tumor necrosis factor alpha (TNF-?). Single nucleotide polymorphisms (SNPs) of TNFA gene, including -238 G/A and -308 G/A, have been associated with alteration in the soluble TNF-? (sTNF-?) expression. The aim was to investigate the association of -238 y -308 TNFA gene SNPs with sTNF-? levels in CKD patients. We included 150 CKD patients and 192 control subjects (CS). Both SNPs were genotyped with polymerase chain reaction-restriction fragment length polymorphism technique and sTNF-? levels were measured by enzyme-linked immunosorbent assay. The genotypic distribution of -238 and -308 SNPs was not significantly different between CKD patients and CS (p > 0.001). However, the sTNF-? levels were higher in CKD, compared to CS (p < 0.001). Also, sTNF-? correlated with creatinine (r = 0.279, p = 0.004), urea (r = 0.325, p = 0.001), phosphorus (r = 0.479, p = 0.001), glomerular filtration rate (r = -0.236, p = 0.019) and monocyte count (r = 0.276, p = 0.010). In conclusion, elevated sTNF-? levels are associated with CKD. However, the -238 and -308 TNFA gene SNPs were not associated with susceptibility to CKD and sTNF-? levels in a Mexican population. � 2014, E-Century Publishing Corporation. All rights reserved.
