Interleukin 10 (IL-10) is an anti-inflammatory cytokine with a protective role in the formation and the development of the atherosclerotic plaque. The aim of the present study was to establish if IL-10 gene polymorphisms are associated with the development of premature coronary artery disease (pCAD) and cardiovascular risk factors in Mexican individuals. Three IL-10 gene polymorphisms [-592C/A (rs1800872), -819C/T (rs1800871), and -1082 A/G (rs1800896)] and IL 10 plasma levels were analyzed in 2266 individuals (1160 pCAD patients and 1106 healthy controls). Under recessive and co-dominant2 models, the -1082 A/G (rsl 800896) G allele was associated with decreased risk of developing pCAD (OR = 0.572, P-rec , = 0.022 and OR = 0.567, P-cod2 = 0.023). In pCAD patients, the polymorphisms were associated with hyperinsulinemia, small and dense LDLs, hypertension, and diabetes mellitus. In the control group, the polymorphisms were associated with hypertension, hyperuricemia, and small and dense LDLs. pCAD patients have significantly higher IL-10 plasma levels than healthy controls [0.91 (0.55-1.67) pg/mL vs 0.45 (0.24-0.98) pg/mL, respectively, P < 0.0001]. Nevertheless, these levels were not associated with the genotypes analyzed in the present study. The results suggest that the IL-10-1082 A/G (rs1800896) G allele is associated with a decreased risk of developing pCAD. In patients and controls, the polymorphisms analyzed were associated with some cardiovascular risk factors. Although, in pCAD patients the IL-10 plasma levels were higher, they were not associated with the genotypes of the polymorphisms examined.
