Diabetic nephropathy (DN) is a serious complication of diabetes mellitus, and its prevalence has been increasing in developed countries. Diabetic nephropathy has become the most common single cause of end-stage renal disease worldwide. Oxidative stress and inflammation factors are hypothesized to play a role in the development of late diabetes complications. Chronic hyperglycemia increases oxidative stress, significantly modifies the structure and function of proteins and lipids, and induces glycoxidation and peroxidation...

BACKGROUND: Inflammation in skeletal muscle is implicated in the pathogenesis of insulin resistance and cachexia but why uremia up-regulates pro-inflammatory cytokines is unknown. Toll-like receptors (TLRs) regulate locally the innate immune responses, but it is unknown whether in chronic kidney disease (CKD) TLR4 muscle signalling is altered. The aim of the study is to investigate whether in CKD muscle, TLRs had abnormal function and may be involved in transcription of pro-inflammatory cytokine...

It has become clear that reactive oxygen species (ROS) contribute to the development of hypertension via myriad effects. ROS are essential for normal cell function; however, they mediate pathologic changes in the brain, the kidney, and blood vessels that contribute to the genesis of chronic hypertension. There is also emerging evidence that ROS contribute to immune activation in hypertension. This article discusses these events and how they coordinate to contribute to hypertension and its consequent end-organ damage...

REVIEW
R Nicoll, M Henein
Arterial calcification is commonly seen in atherosclerosis, chronic kidney disease (CKD) and diabetes and has long been considered a natural progression of atherosclerosis. Yet it is a systemic condition, occurring in a wide and diverse range of disease states and no medical treatment for cardiovascular disease has yet found a way to regress it; on the contrary, lipid-lowering therapy may worsen its progression. Although numerous studies have found associations between calcification and biomarkers, none has yet found a unifying mechanism that explains the calcification found in atherosclerosis, CKD or diabetes and many of the biomarkers are equally associated with atheroma development and cardiovascular events...

Nowadays, obesity is considered as a serious and growing global health problem. It is documented that the overweight and obesity are major risk factors for a series of noncommunicable diseases, and in recent years, the obesity-cancer link has received much attention. Numerous epidemiological studies have shown that obesity is associated with increased risk of several cancer types, including colon, breast, endometrium, liver, kidney, esophagus, gastric, pancreatic, gallbladder, and leukemia, and can also lead to poorer treatment...

Febuxostat is a xanthine oxidase inhibitor that during the last years has successfully replaced allopurinol treatment in patients with chronic kidney disease (CKD) and hyperuricemia. Several adverse events have been observed during therapy with febuxostat. DRESS (Drug Reaction with Eosinophilia and Systemic Symptoms) syndrome induced by febuxostat has been poorly described, mainly in patient with CKD who previously developed allopurinol hypersensitivity syndrome. DRESS syndrome is characterized by manifold cutaneous reactions and systemic disorders with potential devastating consequences...

BACKGROUNDS: Patients with chronic kidney disease (CKD) are at an increased risk of morbidity and mortality from influenza. However, the immunogenicity of influenza vaccine is known to be attenuated in these patients. In this study, the immunogenicity of MF59-adjuvanted and non-adjuvanted trivalent influenza vaccines was compared in CKD patients undergoing hemodialysis (HD). METHODS: During 2013-2014, 179 CKD patients undergoing HD participated in the study. The patients were randomized into either MF59-adjuvanted vaccine group or non-adjuvanted vaccine group and were immunized with the respective vaccine...

CD4(+)Foxp3(+) regulatory T cells (Tregs) are required for normal immune homeostasis. Recent studies suggested that Treg transfer facilitates recovery from acute kidney injury (AKI), but the molecular events that maintain Treg function after adoptive transfer remain unclear. This study aimed to investigate the regulation of mammalian target of rapamycin (mTOR) signaling in the Treg-mediated therapeutic effect on ischemic AKI. We noted significant Treg expansion in C57BL/6 mouse kidney, with enhanced immunosuppressive capacity after renal ischemia/reperfusion...

Systemic lupus erythematosus (SLE) is a chronic multi-factorial autoimmune disease initiated by genetic and environmental factors, which in combination trigger disease onset in susceptible individuals. Damage to the kidney as a consequence of lupus nephritis (LN) is one of the most prevalent and severe outcomes, as LN affects up to 60% of SLE patients and accounts for much of SLE-associated morbidity and mortality. As remarkable strides have been made in unlocking new inflammatory mechanisms associated with signaling molecules of programmed cell death pathways, this review explores the available evidence implicating the action of these pathways specifically within dendritic cells and macrophages in the control of kidney disease...

Nucleotides are key subunits for nucleic acids and provide energy for intracellular metabolism. They can also be released from cells to act physiologically as extracellular messengers or pathologically as danger signals. Extracellular nucleotides stimulate membrane receptors in the P2 and P1 family. P2X are ATP-activated cation channels; P2Y and P1 are G-protein coupled receptors activated by ATP, ADP, UTP, and UDP in the case of P2 or adenosine for P1. Renal P2 receptors influence both vascular contractility and tubular function...

Renal fibrosis is a significant threat to public health globally. Diverse primary aetiologies eventually result in chronic kidney disease (CKD) and immune cells influence this process. The roles of monocytes/macrophages, T cells and mast cells have been carefully examined, whilst only a few studies have focused on the effect of B cells. We investigated B cell function in tubulointerstitial fibrosis induced by unilateral ureteral obstruction (UUO), using genetic B cell-deficient μMT mice or CD20 antibody-mediated B cell depleted mice...

Acquired renal scarring occurs in a subset of patients following febrile urinary tract infections and is associated with hypertension, proteinuria, and chronic kidney disease. Limited knowledge of histopathology, immune cell recruitment and gene expression changes during pyelonephritis restricts the development of therapies to limit renal scarring. Here, we address this knowledge gap using immunocompetent mice with vesicoureteral reflux. Transurethral inoculation of uropathogenic Escherichia coli in C3H/HeOuJ mice leads to renal mucosal injury, tubulointerstitial nephritis, and cortical fibrosis...

Immune system dysfunction is a common condition in chronic kidney disease (CKD). The present study investigated the effect of p-Cresyl sulfate (pCS) on human cell line U937 monocyte-derived macrophages (MDM) activity. MDM (1×10(6) cells/mL) were incubated with pCS (10, 25, or 50μg/mL), with or without lipopolysaccharide (LPS; 25ng/mL) and then evaluated NO production, phagocytosis and antigen-presenting molecules expression (HLA-ABC, HLA-DR, CD80 and CD86). All analyses were performed by flow cytometry. All pCS concentrations were able to increase NO production (49±12...

Recent findings regarding the influence of the microbiota in many inflammatory processes have provided a new way to treat diseases. Now, one may hypothesize that the origin of a plethora of diseases is related to the health of the gut microbiota and its delicate, although complex, interface with the epithelial and immune systems. The 'westernization' of diets, for example, is associated with alterations in the gut microbiota. Such alterations have been found to correlate directly with the increased incidence of diabetes and hypertension, the main causes of chronic kidney diseases (CKDs), which, in turn, have a high estimated prevalence...

Hypertension (HTN) is the most prevalent modifiable risk for cardiovascular disease (CVD) and disorders directly influencing CVD (i.e. obesity, diabetes, chronic kidney disease, obstructive sleep apnea, etc.). About one billion people worldwide have HTN, with American adults having 90% lifetime risk of developing HTN. Despite aggressive campaign for lifestyle changes and advances in drug therapy, HTN remains an immense health, emotional, and economic challenge. This is due, in part, to the fact that ∼50% of HTN patients' blood pressure remains uncontrolled and ∼20% of HTN patients are resistant to or require > antihypertensive drugs...

Hypertension remains an enormous health care burden that affects one third of the population. Despite its prevalence the cause of most cases of hypertension remains unknown. Our laboratory has defined a novel mechanism for hypertension involving adaptive immunity. We found that mice lacking lymphocytes (RAG-1 mice) develop blunted hypertensive responses to a variety of stimuli including chronic angiotensin II infusion, DOCA-salt challenge and norepinephrine infusion. Adoptive transfer of T cells, but not B cells, restores the hypertensive responses to these stimuli...

OBJECTIVE: Chronic kidney disease (CKD) is associated with increased arterial stiffness, which is a well-known predictor of future cardiovascular events. However, the underlying mechanism of arterial stiffening in CKD is not well known. Accelerated immune aging, characterized by expansion of immunosenescent T cell fraction might be involved in the pathogenesis of arterial stiffening in CKD. We aimed to evaluate the relationship between arterial stiffness and immunosenescent T cell (CD8CD57 or CD8CD28 T cell) fraction in patients with CKD...

Obstructive sleep apnea (OSA) causes daytime fatigue and sleepiness, and has an established relationship with cardiovascular and metabolic disease. Recent years have seen the emergence of an evidence base linking OSA with an increased risk of degenerative neurological disease and associated cognitive impairment, an accelerated rate of decline in kidney function with an increased risk of clinically significant chronic kidney disease (CKD), and with a significantly higher rate of cancer incidence and death. This review evaluates the evidence base linking OSA with these seemingly unrelated co-morbidities, and explores potential mechanistic links underpinning their development in patients with OSA, including intermittent hypoxia (IH), sleep fragmentation, sympathetic excitation, and immune dysregulation...
