Beside to this phenomenon, there are also alterations in different components of mineral metabolism, such as those dependent on fibroblast growth factor (FGF)23 and the anti-ageing cofactor klotho. The aim of this work was to explore the association between renal function and systemic levels of IL-6, as well as FGF23 and klotho in the early stages of AKI, analysing the predictive capacity of IL-6 in early mortality associated with AKI.</div></div><div><h3>Materials and methods</h3><div>Plasma levels of IL-6, klotho and FGF23 were analysed in samples from 28 patients with AKI and related to renal function on hospital admission, and after 24 and 72<!--> <!-->hours. In addition, the predictive capacity of IL-6 on AKI-associated mortality was analysed at the three study time points. In an experimental nephrotoxic -AKI mouse model, systemic IL-6 and FGF23 values were also analysed 24 and 72<!--> <!-->hours after induction of kidney damage, as well as in mice overexpressing the anti-ageing protein, klotho.</div></div><div><h3>Results</h3><div>Systemic IL-6 levels increased in AKI patients, especially in hospital admission time, and decreased in parallel with improving renal function. At the same time as IL-6 values increased, there was an increase in FGF23 and a decrease in klotho levels, with a significant and positive correlation between IL-6 and FGF23 levels. In addition, we obtained that systemic IL-6 levels were a good predictor of mortality in these patients, with an area under the curve equal to one at 72<!--> <!-->hours after AKI. In the experimental mouse AKI model, we also observed an increase in plasma levels in both IL-6 and FGF23 after 24<!--> <!-->hours of kidney damage. Nevertheless, in transgenic mice overexpressing klotho, there was no such increase in any of them.</div></div><div><h3>Conclusions</h3><div>There is an association between renal damage and increased levels of IL-6 and FGF23 in patients with AKI, especially on hospital admission time. Moreover, IL-6 levels are able to predict mortality in these patients, being a promising prognostic biomarker at any study time with a strong prediction at 72<!--> <!-->hours after patient admission.
