BACKGROUND: Longer life expectancy is associated with an increasing prevalence of kidney disease. Aging itself may cause renal damage, but the spectrum of kidney disorders that affect elderly patients is diverse. Few studies, mostly form US, Asia and West Europe found differences in the prevalence of some types of kidney diseases between elderly and younger patients based on renal biopsy findings, with varied proportion between glomerulopathies and arterionephrosclerosis as a dominant injury found...

OBJECTIVE: Galactose-deficient IgA1 was evaluated in patients with IgA nephropathy(IgAN) and controls in order to determine the predictive value of galactose-deficient IgA1 in cases of IgA nephropathy. METHODS: PubMed, EMBASE, Cochrane central register of controlled trials, CNKI, CBM disc, and VIP database were searched to identify eligible studies that evaluated a difference in aberrant IgA1 glycosylation in IgAN patients compared with controls. A meta-analysis was conducted to evaluate the impact of galactose-deficient IgA1(Gd-IgA1) levels in different groups...

BACKGROUND AND OBJECTIVES: Staphylococcus infection-associated GN (SAGN) is a well recognized disease entity, particularly because of the frequent IgA-dominant glomerular immunoglobulin staining on kidney biopsy. Biopsy features can resemble two other disease entities - primary IgA nephropathy and Henoch-Schönlein purpura nephritis - posing a diagnostic pitfall. This is clinically relevant because of the crucial difference in the therapeutic approach. The diagnosis of SAGN is further complicated by the variability in the degree of glomerular IgA (and C3) staining, the extent of electron dense immune-type deposits, and positive ANCA serology in some patients...

Mucosal immunity may play a key role in IgA nephropathy (IgAN) and IgA vasculitis with nephritis (IgAVN). IgAVN is characterized by the presence of non-thrombocytopenic palpable purpura, associated with glomerulonephritis with IgA-dominant immune deposits. Recent studies have shown the up-regulation of Toll-like receptors (TLRs) in patients with IgAN or IgAVN. Among TLRs that mediate innate immune reactions, TLR2, TLR4, and TRL5 recognize bacterial components, while TLR3, TLR7, and TLR9 recognize viral components...

Known susceptibility loci together can only explain about 6-8% of the disease heritability of IgA nephropathy (IgAN), suggesting that there are still a large number of genetic variants remained to be discovered. We previously identified IgAN and systemic lupus erythematosus (SLE)/lupus nephritis (LN) shared many loci based on GWAS on Chinese populations. The more recent study with high-density genotyping of immune-related loci in individuals with Asian ancestry identified 10 new and 6 suggestive loci in SLE...

Anti-endothelial cell antibodies (AECA) are frequently detected in patients with systemic lupus erythematosus (SLE), but their pathological role remains unclear. We recently developed a solubilized cell surface protein capture enzyme-linked immunosorbent assay (CSP-ELISA) to detect antibodies against membrane proteins involved in autoimmune reactions. In this study, sera from 51 patients with biopsy-proven lupus nephritis (LN), 25 with SLE without renal involvement (non-LN SLE), 42 disease control (DC) subjects, and 80 healthy control (HC) subjects were tested for IgG- and IgA-AECA for human umbilical vein endothelial cells (HUVEC) and human glomerular EC (HGEC) by using CSP-ELISA...

BACKGROUND: In 1985 we reported that 11% of a cohort of 151 patients with IgA nephritis (IgAN) had developed end-stage renal disease (ESRD) after a follow-up period of 5 years. 15 years later, 35% had developed ESRD. METHODS: We retrieved 125 stored renal biopsy paraffin blocks of the original cohort. From these, 102 patients were included in the present study and scored according to the Oxford classification as 21 specimens with less than 8 glomeruli were excluded and in 2 others, tissue samples were too tiny for a re-block...

BACKGROUND: The concomitant presence of idiopathic membranous nephropathy and IgA nephropathy is rare. Here, we report 9 cases of phospholipase-A2-receptor (PLA2R) positive idiopathic membranous nephritis combined with IgA nephropathy, while reviewing publications regarding the pathological characteristics of this glomerolonephritis complication. CASE PRESENTATION: Nine cases of renal biopsy tissues were retrospectively reviewed, including the clinicopathological features, the results of the immunofluorescence assays, and the electron microscopic examination...

Henoch-Schonlein purpura is an immunoglobulin A (IgA)-immune complex mediated leukocytoclastic vasculitis that classically manifests with palpable purpura, abdominal pain, arthritis, and hematuria or proteinuria. The condition is much more predominant in children (90% of cases) and commonly follows an upper respiratory infection. We present a case of recurrent Henoch-Schonlein purpura (HSP) complicated by nephritis in an adult female initially categorized as IgA nephropathy (IgAN). We review the pathophysiologic basis of HSP nephritis as the variant of HSP accompanied by renal involvement and its pathogenetic commonality with IgA nephropathy...

Small nucleolar RNAs (snoRNAs) have been used for normalization in glomerular microRNA (miRNA) quantification without confirmation of validity. Our aim was to identify glomerular reference miRNAs in IgA nephropathy. We compared miRNAs in human paraffin-embedded renal biopsies from patients with cellular-crescentic IgA-GN (n = 5; crescentic IgA-GN) and non-crescentic IgA-GN (n = 5; IgA-GN) to mild interstitial nephritis without glomerular abnormalities (controls, n = 5). Laser-microdissected glomeruli were used for expression profiling of 762 miRNAs by low-density TaqMan arrays (cards A and B)...

There is limited data on the etiology, clinical and histopathological spectrum and outcomes of crescentic glomerulonephritis (CrGN) in adult Indian population. This prospective study was done to evaluate the etiology, clinicohistological patterns and predictors of outcome of CrGN in South Indian population. All the patients received standard protocol based immunosuppression in addition to supportive care. Immune-complex glomerulonephritis (ICGN) was the most common etiology (n = 31; 77.5%) followed by pauci-immune glomerulonephritis (PauciGN; n = 8; 20%) and anti-glomerular basement membrane disease (n = 1; 2...

Henoch-Schonlein purpura, also called IgA-vasculitis, is a systemic small vessels vasculitis with immunoglobulin A1-dominant immune deposits. The optimal treatment remains controversial. Because IgA-vasculitis is characterized by leukocyte infiltration of the blood vessel walls along with immunoglobulin A deposition, and because glucocorticosteroids inhibit inflammatory processes, early administration of glucocorticosteroids has been postulated to be effective, but this indication remains controversial. Immunosuppressive agents (azathioprine, cyclophosphamide, cyclosporine, mycophenolate) have been used in combination with glucocorticosteroids without definitive evidence of effectiveness...

Differences in kidney transplantation outcomes across GN subtypes have rarely been studied. From the US Renal Data System, we identified all adult (≥18 years) first kidney transplant recipients (1996-2011) with ESRD attributed to one of six GN subtypes or two comparator kidney diseases. We computed hazard ratios (HRs) for death, all-cause allograft failure, and allograft failure excluding death as a cause (competing risks framework) using Cox proportional hazards regression. Among the 32,131 patients with GN studied, patients with IgA nephropathy (IgAN) had the lowest mortality rates and patients with IgAN or vasculitis had the lowest allograft failure rates...

Renal biopsy is the gold standard method for determining the diagnosis, treatment, and prognosis in children with renal disease. This study aims to evaluate the histopathological features of pediatric renal biopsies obtained from the national nephrology registry in the last two decades. Data recorded in the Turkish Society of Nephrology Registry System (TSNRS) in 1991 as well as in between 2001 and 2010 were analyzed. A total of 3892 biopsies were recorded; with the least number in 1991 (total 103 biopsies from 17 centers) and the highest number in 2008 (total 654 biopsies from 23 centers)...

INTRODUCTION: Henoch-Schönlein purpura (HSP) is a small blood vessel vasculitis, which usually manifests during childhood. The exact cause of the disease is unknown. CASE REPORT: We reported a 14-year-old girl who had been admitted to our clinic due to the appearance of red macules on her extremities and face, vomiting, and pain in the abdomen and joints. The patient was initially diagnosed with Henoch-Schönlein purpura. At the end of the fourth week of illness, larvae of Strongyloides stercoralis were detected in stool samples...

Mary H Foster
Animal models are indispensable for the study of glomerulonephritis, a group of diseases that destroy kidneys but for which specific therapies do not yet exist. Novel interventions are urgently needed, but their rational design requires suitable in vivo platforms to identify and test new candidates. Animal models can recreate the complex immunologic microenvironments that foster human autoimmunity and nephritis and provide access to tissue compartments not readily examined in patients. Study of rat Heymann nephritis identified fundamental disease mechanisms that ultimately revolutionized our understanding of human membranous nephropathy...

The polymeric IgR (pIgR) is a central component in the transport of IgA across enterocytes and thereby plays a crucial role in the defense against enteropathogens and in the regulation of circulating IgA levels. The present study was performed to address the novel regulation of pIgR expression in intestinal epithelia undergoing ribosome inactivation. Insults to mucosa that led to ribosome inactivation attenuated pIgR expression in enterocytes. However, IFN regulatory factor-1 (IRF-1) as a central transcription factor of pIgR induction was superinduced by ribosome inactivation in the presence of IFN-γ as a result of mRNA stabilization by the RNA-binding protein HuR...

Systemic erythematosus lupus (SLE) is a multisystemic autoimmune disease which has nephritis as one of the most striking manifestations. Although it can coexist with other autoimmune diseases, and determine the predisposition to various infectious complications, SLE is rarely described in association with non-lupus nephropathies etiologies. We report the rare association of SLE and primary IgA nephropathy (IgAN), the most frequent primary glomerulopathy in the world population. The patient was diagnosed with SLE due to the occurrence of malar rash, alopecia, pleural effusion, proteinuria, ANA 1: 1280, nuclear fine speckled pattern, and anticardiolipin IgM and 280U/mL...

BACKGROUND: Little information is currently available on the development of tubulointerstitial lesions in children with Henoch-Schönlein nephritis (HSN). To identify the impact of the development of tubulointerstitial changes in HSN, we retrospectively analyzed renal biopsies obtained from children with HSN. METHODS: Twenty-eight children with HSN from whom serial renal biopsies had been obtained before and after immunosuppressive therapy were enrolled in the study...
