BACKGROUND: Various renal manifestations are known to develop in patients with liver disease, including chronic hepatitis and cirrhosis. CASE PRESENTATION: We evaluated renal disease in two 47-year-old Japanese men with liver cirrhosis and chronic alcoholism for 34 years and 27 years, respectively. Renal biopsy demonstrated massive wire loop-like deposits in the subendothelial space of the glomerular basement membrane and in the mesangium. However, immunofluorescence was only positive for IgA and C3, and electron microscopy did not reveal any organized structures in the electron-dense deposits...

Diabetic nephropathy (DN) is a major cause of chronic kidney disease. We aimed to investigate the effect of the low-protein diets (LPD) supplemented with ketoacids (LPD+KA) in KKAy mice, an early type 2 DN model. KKAy mice were treated with normal protein diet (NPD), LPD or LPD+KA from 12 to 24 weeks of age. A period of 12-week treatment with LPD significantly reduced albuminuria as compared with that observed after NPD treatment. Treatment with LPD+KA further reduced albuminuria as compared with that observed with LPD treatment alone...

Renal impairment (RI) is a common complication of multiple myeloma (MM), which is presented as chronic kidney disease (CKD) or acute kidney injury (AKI). The typical pathological feature is cast nephropathy. Presently international system staging (ISS) is used in evaluating MM. Although the classic Durie-Salmon staging system could be still used in clinical practice, it may miss out some patients with renal impairment. For evaluations of RI in MM patients with CKD, it's recommended to assess the estimated glomerular filtration rate (eGFR) by creatinine based formula CKD-epidemiology collaboration (EPI) or modification of diet in renal disease(MDRD) and to stage the renal injuries according to 2013 Kidney Disease Improving Global Outcomes (KDIGO) CKD guidelines...

BACKGROUND/AIMS: Diabetic kidney disease (DKD) is one of the most frequent microvascular complications of diabetes and is the leading cause of end-stage kidney disease worldwide. In patients with diabetes, non-diabetic kidney disease (NDKD) can also occur. NDKD can be either alone or superimposed with the DKD. In this study, we aimed to investigate the utility of kidney biopsy in patients with type 2 diabetes mellitus (T2DM) and the predictability of diagnosing DKD versus NDKD from clinical and laboratory data...

The phospholipase A2 receptor (PLA2R1) is the major autoantigen in primary membranous nephropathy. Several PLA2R1 epitopes have been characterized, and a retrospective study identified PLA2R1 epitope spreading as a potential indicator of poor prognosis. Here, we analyzed the predictive value of anti-PLA2R1 antibody (PLA2R1-Ab) titers and epitope spreading in a prospective cohort of 58 patients positive for PLA2R1-Ab randomly allocated to rituximab (n=29) or antiproteinuric therapy alone (n=29). At baseline, the epitope profile (CysR, CysRC1, CysRC7, or CysRC1C7) did not correlate with age, sex, time from diagnosis, proteinuria, or serum albumin, but epitope spreading strongly correlated with PLA2R1-Ab titer (P<0...

Background: Immunosuppression (IS) is the main treatment for most types of glomerulonephritis (GN). Quantifying the cost of IS is necessary to ensure equitable access to therapies and optimal health outcomes, but the real-world cost of IS treatment for GN is largely unknown. We examined temporal changes in the population-level IS medication costs for GN over a 14-year period in a large Canadian province. Methods: We linked a provincial pathology database (containing all GN cases from 2000 to 2012) with renal and medication administrative databases to capture clinical characteristics and IS medications, with follow-up until 2013...

INTRODUCTION: Membranous nephropathy (MN) is among the most common causes of nephrotic syndrome in adults worldwide. Most patients have primary MN (PMN), an autoimmune condition associated with the IgG anti-PLA2 R autoantibody. For patients with severe disease, standard of care continues to be a 6-month regime of rotating high dose steroids and immunosuppression that comes with a significant side-effect profile. Immunoadsorption is a relatively safe procedure for the extracorporeal removal of specific immunoglobulins without the need for medications...

Immunoglobulin G4-related disease (IgG4-RD) is a recently recognized clinical entity that often involves multiple organs; it is characterized by high levels of serum immunoglobulin G4 (IgG4), dense infiltration of IgG4+ cells, and storiform fibrosis. Cellular immunity, particularly T cell-mediated immunity, has been implicated in the pathogenesis of IgG4-RD. The most frequent renal manifestations of IgG4-RD are IgG4-related tubulointerstitial nephritis, membranous glomerulonephropathy (MGN), and obstructive nephropathy secondary to urinary tract obstruction due to IgG4-related retroperitoneal fibrosis, prostatitis, or ureter inflammation...

The membranous nephropathy (MN) is the major cause of nephrotic syndrome in in the adult, account for 20% of cases with annual incidence is 1 in 100.000. In the past 10 years, the role of podocytes has been identified; environmental triggers in genetically predisposed patients can activate podocytes to exhibit antigenic epitopes (receptor of phospholipase A2, thrombospondin type 1) that become targets of specific autoantibodies with subsequent complement activation. The discovery of this mechanisms has opened new horizons in the therapy of MN and novel drugs are available with more specific mechanism of action...

In the last 10 years, basic science and clinical research have made important contributions to the understanding and management of primary membranous nephropathy (MN). The identification of antibodies directed against the M-type phospholipase A2 receptor (PLA2R) and thrombospondin type-1 domain-containing 7A protein have added a new perspective on diagnosis, monitoring the immunological activity, predicting prognosis and guiding therapy in patients with primary MN. Mounting evidence suggests that quantification and follow-up of antiPLA2R Abs levels can help in assessing prognosis and evaluate the response to treatment...

BACKGROUND: Idiopathic membranous nephropathy (IMN) is one of the most common causes of nephrotic syndrome in adults. A proportion of patients will experience spontaneous remission and the decision to offer immunosuppression is guided by the presence of adverse prognostic features. Data relating to the efficacy of different immunosuppressive protocols is lacking, in particular there are little data available on the efficacy or benefits of an intravenous (IV) cyclophosphamide-based regimen...
