IL6 and diabetic kidney disease: In a meta-analysis of the IL-6 -174G/C polymorphism and the risk of DKD, which evaluated whether this polymorphism may affect early DKD, Cui et al. found an association between the allelic and recessive genetic models (G vs. C: OR = 1.10, 95% CI 1.03–1.18, p = 0.006; GG vs. CC+GC: OR = 1.11, 95% CI 1.02–1.21, p = 0.016) [71].
