The development of tissue fibrosis in the context of a wound-healing response to injury is common to many chronic diseases. Unregulated or persistent fibrogenesis may lead to structural and functional changes in organs that increase the risk of significant morbidity and mortality. We will explore the natural history, epidemiology, and pathogenesis of fibrotic disease affecting the lungs, kidneys, and liver as dysfunction of these organs is responsible for a substantial proportion of global mortality. For many patients with end-stage disease, organ transplantation is the only effective therapy to prolong life...

The implications of epithelial‑mesenchymal transdifferentiation (EMT) have extended beyond the confines of renal fibrosis to renal tubulointerstitial fibrosis. It has been proposed that EMT may be one of the mechanisms involved in the pathogenesis of renal fibrosis. However, the underlying mechanisms remain unknown. Transforming growth factor (TGF)‑β1 is considered to be an important cytokine which regulates the transdifferentiation of tubular epithelial cells into myofibroblasts in renal tubulointerstitial fibrosis...

Chronic kidney disease leads to dysfunction of renal erythropoietin-producing cells, resulting in a decrease in erythrocyte production. A decrease in oxygen delivery to vital organs due to anemia results in worse quality of life and is associated with poor prognosis of the patients. Treatment with human recombinant erythropoietin or its improved version of erythropoiesis-stimulating agent (ESA) with a longer half-life is effective. However, some patients show hyporesponsiveness to ESA. Hyporesponsiveness to ESA, which can be induced by factors such as inflammation and uremic toxins, is associated with poor prognosis...

In non-dialysis-chronic kidney disease (CKD), iron deficiency is a frequent nutritional disorder due to either the greater tendency to occult gastrointestinal bleeding or to the chronic inflammatory state resulting in a reduced intestinal iron reabsorption through an increased synthesis of hepcidin. These phenomenon are responsible for a negative iron balance that compromises erythropoiesis and contributes to the pathogenesis of anemia in CKD. Several laboratory tests are now available to allow an adequate diagnosis of iron deficiency...

Besides liver cirrhosis and hepatocellular carcinoma, chronic hepatitis C virus (HCV) infection is associated with many extrahepatic manifestations (EHMs). HCV exhibits lymphotropism that is responsible for various EHM. An important characteristic of HCV is escape from the immune system, which enables it to produce chronic infections and autoimmune disorders along with accumulation of circulating immune complexes. These EHMs have large spectrum, because they affect many organs such as heart, lungs, kidney, brain, thyroid, and skin...

Major achievements in the understanding of thrombotic microangiopathies (TMA) have not only resulted in a reclassification of TMA but most of all they have culminated in the design of new treatments and have enabled clinicians to better delineate their prognosis. Recent multicenter studies have improved our understanding of the prognosis of atypical hemolytic and uremic syndromes (aHUS). More specifically, they have highlighted the role of genetic testing on predicting the recurrence of aHUS, the risk of chronic kidney disease and the recurrence following kidney transplantation...

The kidney is the target organ of insulin with abundant insulin receptors. Thereinto,the renal intrinsic cells including glomerular podocytes,endothelial cells,mesangial cells,renal tubular epitheliums and collecting duct epithelial cells are all highly sensitive to insulin as the effector cells. Furthermore,the structural and functional abnormalities of these cells are closely related to insulin and its receptors activity. It is reported that the chronic kidney disease(CKD)patients have systemic or renal insulin resistance(IR)...

Life expectancy in patients with all stages of chronic kidney disease (CKD) falls far short of that in the general population. Cardiovascular disease is the leading cause of mortality in pediatric patients with CKD. In contrast to the intimal atherosclerotic lesions that characterize cardiovascular disease in the general population, vascular endothelial dysfunction, medial arterial calcification, and cardiac dysfunction contribute to cardiovascular pathological conditions in CKD. The pathogenesis of these lesions, the origins of which can be identified in the absence of traditional cardiovascular risk factors, is incompletely understood...

Chronic kidney disease (CKD) is a progressive pathological condition marked by a gradual loss of kidney function. Treatment of CKD is most effective when diagnosed at an early stage and patients are still asymptomatic. However, current diagnostic biomarkers (e.g., serum creatinine and urine albumin) are insufficient for prediction of the pathogenesis of the disease. To address this need, we applied a cell-SELEX (systematic evolution of ligands by exponential enrichment) approach and identified a series of DNA aptamers, which exhibit high affinity and selectivity for cytokine-stimulated cells, resembling some aspects of a CKD phenotype...

Despite marked improvements in renal replacement therapy during the last 30 years, the age-adjusted mortality rate in end-stage renal disease (ESRD) patients is still unacceptably high and comparable to that of many malignancies. Cardiovascular disease (CVD) remains the major cause of morbidity and mortality in ESRD patients. However, traditional risk factors can only partially explain the high premature cardiovascular burden in this population. Nontraditional risk factors, including persistent low-grade inflammation, are critical in the pathogenesis of atherosclerosis, vascular calcification, and other causes of CVD and may also contribute to protein-energy wasting and other complications in chronic kidney disease (CKD) patients...

We present a new preclinical model to study treatment, resolution, and sequelae of severe ascending pyelonephritis. Urinary tract infection (UTI), primarily caused by uropathogenic Escherichia coli (UPEC), is a common disease in children. Severe pyelonephritis is the primary cause of acquired renal scarring in childhood, which may eventually lead to hypertension and chronic kidney disease in a small but important fraction of patients. Preclinical modeling of UTI utilizes almost exclusively females, which (in most mouse strains) exhibit inherent resistance to severe ascending kidney infection; consequently, no existing preclinical model has assessed the consequences of recovery from pyelonephritis following antibiotic treatment...

The idiopathic nephrotic syndrome is a common chronic kidney diseases in children defined by the association of massive proteinuria and hypoalbuminemia in a relapsing/remission course, with histological aspect of minimal changes (also called minimal change disease) in the majority of the cases, but its pathogenesis remains not very well known. Clinical and immunological studies have consistently shown a relationship between atopic diathesis, immunoglobulin E and cytokines involved in immunoglobulin E synthesis and idiopathic nephrotic syndrome...

In light of the rapid increase in the number of obesity incidences worldwide, obesity has become an independent risk factor for chronic kidney disease. Obesity-related glomerulopathy (ORG) is characterized by glomerulomegaly in the presence or absence of focal and segmental glomerulosclerosis lesions. IgM and complement 3 (C3) nonspecifically deposit in lesions without immune-complex-type deposits during ORG immunofluorescence. ORG-associated glomerulomegaly and focal and segmental glomerulosclerosis can superimpose on other renal pathologies...

Primary myelofibrosis (PMF) is an uncommon form of myeloproliferative neoplasm (MPN) characterized by a proliferation of predominantly megakaryocytes and granulocytes in the bone marrow that, in fully-developed disease, is associated with reactive deposition of fibrous connective tissue, extramedullary hematopoiesis (EMH), and splenomegaly. Kidney involvement is rare and clinically presents with proteinuria, nephrotic syndrome, and renal insufficiency. Renal damage can be due to EMH and glomerulopathy. Renal EMH presents three patterns: infiltration of the interstitium with possible renal failure caused by functional damage of parenchyma and vessels, infiltration of capsule and pericapsular adipose tissue, and sclerosing mass-like lesions that can cause hydronephrosis and hydroureter with obstructive uropathy and renal failure...

BACKGROUND: High aldosterone level may contribute to pathogenesis of hypertension, vessels damage and cardiovascular system deterioration in chronic kidney disease patients. Besides its classical action via mineralocorticoid receptor, aldosterone is also involved in cell growth, inflammation, oxidative stress, endothelial dysfunction and exerts fibroproliferative effects. The aim of the study was to assess whether aldosterone antagonist treatment may influence serum level of inflammatory, fibrosis, thrombosis and mineral-bone metabolism markers in peritoneal dialysis (PD) patients and blood pressure, aortic stiffness, echocardiographic indices after 12 months of treatment...

Acute kidney injury caused by ischemia-reperfusion injury (IRI) is a major risk factor for chronic kidney disease, which is characterized by renal interstitial fibrosis. However, the molecular mechanisms underlying renal fibrosis induced by IRI are not fully understood. Our results showed that interleukin (IL)-33 was induced markedly after IRI insult, and the kidneys of mice following IRI plus IL-33 treatment presented more severe renal fibrosis compared with mice treated with IRI alone. Therefore, we investigated whether inhibition of IL-33 protects against IRI-induced renal fibrosis...

Background: Chronic kidney disease-mineral and bone disorder (CKD-MBD) has been implicated in vascular calcification pathogenesis. CKD-MBD results in alterations in the number and function of circulating endothelial progenitor cells (EPCs), physiological regulators of angiogenesis and vessel repair, commonly defined as proangiogenic progenitor cells (PACs) by the antigen pattern CD34+CD133+KDR+CD45- and putative EPCs by the pattern CD34+CD133-KDR+CD45-. These cells might acquire a calcifying phenotype in CKD-MBD, expressing mineralization biomarkers...

The endoplasmic reticulum (ER) is a cellular organelle specialized in the synthesis, folding, assembly, and modification of proteins. In situations of increased protein demand, complex signaling pathways, termed the unfolded protein response (UPR), influence a series of cellular feedback loops to strictly control ER function. While initially a compensatory attempt to maintain cellular homeostasis, chronic activation of the UPR, known as ER stress, leads to sustained changes in cellular function. A growing body of literature points to ER stress in diverse cardioregulatory systems, including the brain, kidney and vasculature, as central to the development of hypertension...

AIMS: Asymmetric dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide synthase, is mainly degraded by dimethylarginine dimethylaminohydrolase (DDAH). Emerging evidence suggests that plasma ADMA accumulation and DDAH1 activity/expression reduction are linked to chronic kidney disease (CKD) pathology, but the mechanisms remain largely unknown. Here, we examined the role of ADMA/DDAH1 in the epithelial-mesenchymal transition (EMT) of tubular epithelial cells (TECs), an important mechanism for the pathogenesis of renal fibrosis...
