The purpose of this study was to examine the association between chosen cytokines, such as IFN-γ, IL-10, IL-2p70, IL-6, and kidney function as well as the body composition and nutritional markers in patients with CKD and diabetes mellitus type 2.
In CKD patients, serum IL-6 above the median value was associated with carotid plaque (OR: 2.11; 95% CI: 1.74 - 2.57, p = 0.004), with excess risk confined to the group with high IL-6 levels.
Future studies should investigate whether inflammatory pathways that involve IL-6 and TNF-α increase susceptibility to infection among individuals with CKD.
To explore the role of miR-206 in CKD, the model of CKD rats was established to detect glomerular sclerosis index (GSI), contents of interleukin-6 (IL-6) and transforming growth factor-beta1 (TGF-β1), and expression of type IV collagen.
In contrast, higher levels of IL-6 in serum and urine in children after HUS compared to healthy children and the negative correlation of L-FABP concentration and eGFR in children after 6 month observation after HUS may confirm their participation in CKD.
While IL-6 was associated with augmentation index (standardized β = 0.224; P < .001) and central pulse pressure (standardized β = 0.162; P = .001) when adjusted for MBP and heart rate, this relationship was not significant after adjusting for potential confounders.This study suggests a potential role of IL-6 for CKD-related aortic stiffness.
Renal IL-6 mRNA expression was increased in mice with either AKI or CKD, suggesting the kidney is the source for the increased serum IL-6 levels in the uremic state.
Serum IL-4, IL-6, and TNF-α were found significantly higher in T2DM with CKD compared to T2DM and healthy ones. mRNA expression of IL-4, IL-6 and NF-кβ are also found significantly higher in T2DM with CKD.
This case-control study aimed to study the levels of hepcidin and other proinflammatory markers (IL-6, TNF-α, hs-CRP) and their relation with anemia in iron- and erythropoietin-naïve, non-dialysis CKD (stage 3 - 5) patients.
Probiotics supplementation may reduce the levels of PCS and elevate the levels of IL-6 whereby protecting the intestinal epithelial barrier of patients with CKD.
These findings suggest that IL-6, D-dimer and s-VCAM may be useful biomarkers for improving risk prediction, but further studies are needed examining the role of these biomarkers in elderly individuals with CKD.
Additionally, we summarize the roles of IL-6 in several renal diseases, such as IgA nephropathy, lupus nephritis, diabetic nephropathy, acute kidney injury, and chronic kidney disease.
Compared with sham mice, the expression of interleukin-6 and atrophy-related factors such as myostatin and atrogin-1 was increased in the skeletal muscle of CKD mice, whereas muscular Akt phosphorylation was decreased.
The biomarker profiles associated with mortality differed significantly by CKD etiology as follows: DKD was associated with CysC (HR 1.3, 95% CI 1.0-1.6), ADMA (HR 1.3, 95% CI 1.1-1.6), and NT-proBNP (HR 1.7, 95% CI 1.4-2.1), GN was associated with FGF23 (HR 1.8, 95% CI 1.1-2.8), TnI (HR 3.6, 95% CI 1.3-9.5), and transforming growth factor-beta (HR 0.6, 95% CI 0.4-0.9) and PCK/TIN was associated with ADMA (HR 1.5, 95% CI 1.3-1.8) and IL-6 (HR 2.1, 95% CI 1.5-3.1).
When compared with the CTR group, subtotal nephrectomy in the CKD group significantly elevated blood pressure; increased the left ventricular mass, end-diastolic left ventricular internal dimension, left ventricular end-diastolic posterior wall thickness and end-diastolic interventricular septum thickness; prolonged the QT interval, corrected QT interval, the interval from the peak to the end of the T wave (Tp-e) and the corrected Tp-e interval; and increased the QT dispersion and the Tp-e/QT ratio; decreased the VFT; and increased the serum concentrations of noradrenaline, C-reactive protein and interleukin-6.
Plasma IL-6 rises early in CKD and does not show any further increase at more severe stages of CKD, whereas TNF-α is inversely associated with the GFR indicating a substantial difference in the dynamics of the relationship between these cytokines and renal function.
