Interferon regulatory factor 4 (IRF4) is expressed in immune cells and is a member of the interferon regulatory factor family. Recently, it has been found that IRF4 plays important roles in the acute kidney injury (AKI)-chronic kidney disease (CKD) transition, glomerular diseases and kidney allograft rejection. In particular, the relationship between IRF4 and the AKI-CKD transition has attracted widespread attention. Furthermore, it was also found that the deficiency of IRF4 hindered the transition from AKI to CKD through the suppression of macrophage-to-fibroblast conversion, inhibition of M1-M2 macrophage polarization, and reduction in neutrophil inward flow. Additionally, an examination of the crucial role of IRF4 in glomerular disease was conducted. It was reported that inhibiting IRF4 could alleviate the progression of glomerular disease, and potential physiopathology mechanisms associated with IRF4 were postulated. Lastly, IRF4 was found to have detrimental effects on the development of antibody-mediated rejection (ABMR) and T-cell-mediated rejection (TCMR).

Background: The variations and their correlation of inflammation and oxidative stress in chronic kidney disease (CKD) have not been thoroughly understood. Materials and methods: Biomarkers of inflammation and oxidative stress were measured in a cohort of 176 patients with CKD ranging from stage 1 to 5 and 67 healthy controls. Correlation analysis in levels between inflammation and oxidative stress was also performed with estimated glomerular filtration rate (eGFR) using the Modification of Diet in Renal Disease (MDRD) formula. Concentrations of serum creatinine (Scr), hs-CRP (hypersensitive C reactive protein) and MDA (malondialdehyde) of these participants were measured again after 12 month follow-up. Results: In the present study, with the development of CKD, serum levels of hs-CRP, interleukin-6 (IL-6) and MDA were significantly increased, and the serum levels of SOD (superoxide dismutase) and GSH-PX (glutathione peroxidase) were significantly decreased in these participants. eGFR was inversely associated with MDA and positively with SOD and GSH-PX when adjusting for age and hypertension therapy. IL-6 and hs-CRP were positively correlated with MDA, and negatively associated with SOD and GSH-PX. Notably, after 12-month follow-up, the increase in Scr was positively associated with the increase in hs-CRP ( p < 0.01) and MDA ( p < 0.05), respectively. Conclusions: Inflammation and oxidative stress interacted with each other and played pivotal roles in the development of CKD. Variation in eGFR was parallel with the changes of oxidative stress and inflammation when CKD developing. [ABSTRACT FROM AUTHOR]

Background: Dialysis and its complications were debated recently. There was lack of an adjuvant renal replacement method to reduce the complications of patients with chronic renal failure and dialysis itself. Materials and methods: In this article, we reviewed the role of thermal sweating in treating of the patients with chronic renal failure, and the role of traditional Chinese medicine in the therapy of chronic kidney diseases. Results: Thermal sweating can reduce interdialytic weight gain and improve the patients' blood pressure; Chinese herbal medicine can promote the excretion of uremic toxicities and relieve the skin disorders of these patients. Conclusions: Traditional Chinese medicine-mediated hot bath could be one of the adjuvant renal replacement methods. [ABSTRACT FROM AUTHOR]

Background. Thin basement membrane nephropathy (TBMN) patients with additional inflammatory diseases and IgA nephropathy (IgAN) have not been reported before. It was unclear that if the prognosis of these patients is better or worse than patients with IgAN and TBMN, or IgAN patients with normal glomerular basement membrane (GBM). Methods. We first reported five TBMN patients with additional inflammatory diseases and IgAN: three were with rheumatoid arthritis, and two had Crohn's disease. Clinical and laboratory features were analyzed between this group (group 3), IgAN patients with normal GBM (group 1), and patients with TBMN and IgAN (group 2). Results. Significant differences were observed in serum levels of IgG, IgA, and IgM between groups 1 and 3, p < 0.001, and between groups 2 and 3, p < 0.001. Glomerular filtration rate (GFR) in group 3 was significantly lower than that of groups 1 and 2, p < 0.01, respectively. Conclusion. The prognosis of these patients is worse than patients with IgAN and TBMN or IgAN patients with normal GBM. Serum immunoglobulin levels and GFR in these patients were different from patients with IgAN and TBMN, or IgAN patients with normal GBM. [ABSTRACT FROM AUTHOR]
