OBJECTIVES: Anemia is an important prognostic factor in hemodialysis patients. It has been reported that parathyroidectomy ameliorates anemia and reduces the requirement of postoperative erythropoiesis-stimulating agents. The objective of this study was to assess the effect of cinacalcet, which is considered as a pharmacological parathyroidectomy, on anemia in hemodialysis patients. METHODS: We used data from a prospective cohort of Japanese hemodialysis patients with secondary hyperparathyroidism; the criteria were: intact parathyroid hormone concentrations ≥ 180 pg/mL or use of an intravenous or oral vitamin D receptor activator...

Hypertension prevalence rates in most urbanized areas of Africa range from 20-30%, with a recent systematic review reporting 16.2% for sub-Saharan Africa. These rates are lower than those in the West but the age standardized rates are higher than in other regions of the world. The attendant morbidity and mortality are disproportionately high. For example, failure of nocturnal dipping and microalbuminuria, predictive of vascular disease, occur relatively early in the course of hypertension and predispose to early vascular disease...

Studies published from centers across India have reported different and contradicting patterns of glomerular disease. In this retrospective study, we report our experience from a Tertiary Care Center in Northwest India. A total of 702 renal biopsies performed between 2008 and 2013 were reviewed of which 80 were excluded from the study because of having insufficient records or if the biopsies were taken from an allograft. The study included 411 males (66.1 %) and 211 females (33.9%) with an age range of 12-70 years (mean 30...

Cathepsins are a class of proteases with diverse biological activities inside and, in part, also outside cells. Recent studies suggest that cathepsins are involved in the pathogenesis of diabetic nephropathy and in disease activity of autoimmune immune complex glomerulonephritis. Targeting specific cathepsins with suitable antagonists may hold promises for therapeutic interventions.

Protease-activated receptors (PARs) are a well-known family of transmembrane G-protein-coupled receptors (GPCRs). To date, four PARs have been identified and PAR1 and PAR2 are the most abundant receptors, which were shown to be expressed in the kidney vascular and tubular cells. PAR signaling is mediated by an N-terminus tethered ligands that can be unmasked by serine protease cleavage. PARs are activated by endogenous serine proteases, such as thrombin (acts on PARs 1, 3 and 4) and trypsin (PAR2). PARs can be involved in glomerular, microvascular and inflammatory regulation of renal function in both normal and pathological conditions...

Extrahepatic manifestations of hepatitis C virus infection (HCV) are very common. The most common of these is mixed cryoglobulinaemia. Anti-HCV antibodies and viral ribonucleic acid, HCV RNA, can be found in the cryoprecipitates, together with the rheumatoid factor. Cryoglobulins consist of a complex of immunoglobulins that in vitro precipitate upon the cooling bellow the human body temperature. Vasculitis is caused by the deposition of such immune complexes in the small blood vessels. A link with the HCV infection is considered to be established with membranoproliferative glomerulonephritis, leukocytoclastic vasculitis, lymphoproliferative disorders (in particular B cell lymphoma), Sjögren and sicca syndrome, lichen planus, porfyria cutanea tarda and diabetes mellitus...

Kimmelstiel and Wilson originally described nodular glomerulosclerosis as the pathognomonic lesion of diabetic nephropathy. Nevertheless, nodular glomerulosclerosis pattern can rarely occur in non-diabetic patients. In such cases, the differential diagnosis includes membranoproliferative glomerulonephritis, light or heavy chain deposition disease, amyloidosis, fibrillary and immunotactoid glomerulonephritis and chronic hypoxic or ischemic conditions. In cases that the above entities cannot be proven, the term idiopathic nodular glomerulosclerosis is given...

The glomerulus has 3 resident cells namely mesangial cells that produce the mesangial matrix, endothelial cells that line the glomerular capillaries, and podocytes that cover the outer surface of the glomerular basement membrane. Parietal epithelial cells (PrECs), which line the Bowman's capsule are not part of the glomerular tuft but may have an important role in the normal function of the glomerulus. A significant progress has been made in recent years regarding our understanding of the role and function of these cells in normal kidney and in kidneys with various types of glomerulopathy...

Galectins are evolutionary conserved β-galactoside binding proteins with a carbohydrate-recognition domain (CRD) of approximately 130 amino acids. In mammals, 15 members of the galectin family have been identified and classified into three subtypes according to CRD organization: prototype, tandem repeat-type and chimera-type galectins. Galectin-3 (gal-3) is the only chimera type galectin in vertebrates containing one CRD linked to an unusual long N-terminal domain which displays non-lectin dependent activities...

Non-coding single nucleotide polymorphisms that repress PTPN2 expression have been linked with the development of type 1 diabetes, rheumatoid arthritis and Crohn's disease. PTPN2 attenuates CD8(+) T cell responses to self and prevents overt autoreactivity in the context of T cell homeostasis and antigen cross-presentation. The role of PTPN2 in other immune subsets in the development of autoimmunity remains unclear. Here we show that the inducible deletion of PTPN2 in hematopoietic compartment of adult non-autoimmune prone mice results in systemic inflammation and autoimmunity...

BACKGROUND/AIMS: Podocytes play an important role in maintaining the glomerular filtration barrier and in formation of the slit diaphragm. Podocyte loss is associated with chronic kidney disease progression, but it is not clear whether urinary podocyte proteins in urine reflect the clinical extent of glomerular damage. We investigated the correlation between the amounts of urinary podocyte proteins and renal function and albuminuria. METHODS: The study enrolled 33 patients with diabetic kidney disease or glomerular disease and measured urinary podocytes proteins using Western blotting...

Cardiorenal syndromes refer to clinical and metabolic consequences of acute and chronic heart failure or kidney disease on other organ. Recent studies have further clarified the pathophysiological mechanisms behind the different types of cardiorenal syndromes and propose a new classification. The cardiorenal syndrome type 1 corresponds to an acute heart failure (cardiogenic shock, acute decompensated congestive heart failure) which induces acute renal dysfunction. In the cardiorenal syndrome type 2 heart failure is chronic (congestive heart failure) and induces chronic kidney damages in the long-term...

Chronic viral hepatitis B and C may associate different extrahepatic manifestations and renal disease is the most frequent. Kidney damage is represented in most cases by glomerulopathies, which include membranous nephropathy, membranoproliferative glomerulonephritis (MPGN), IgA nephropathy, focal and segmental glomerulosclerosis and diabetic nephropathy. We conducted a retrospective study on 639 patients diagnosed with chronic viral hepatitis B and C and different renal diseases. Complete evaluation of liver and renal status was performed and, in selected cases, renal biopsy...
