Immunoglobulin A Nephropathy (IgAN), is the most common primary glomerulonephritis; the reported recurrence rate of IgAN after renal transplantation is as high as 13-50%. The impact of immunosuppressive therapy and steroid withdrawal on the risk of recurrence of IgAN is still under debate. We performed a retrospective single center study, selecting 123 kidney transplants (rtx) in 120 patients, between January 1995 and December 2012, with IgAN on the native kidney. In 51/123 at least one post transplantation biopsy for clinical indication was performed; in 28/51 transplants IgAN recurrence (IgANr) was demonstrated...

The presence of human immunodeficiency virus (HIV)-related kidney disease is an important cause of mortality and morbidity. HIV infection induces renal injury by direct cytotoxicity or immune complex-mediated glomerulonephritis in patients with genetic susceptibility factors. In the last decades, with the development and diffusion of combination antiretroviral therapy, which has prolonged patient survival, there has been a shift in the spectrum of renal diseases in HIV-infected patients, with the decrease of glomerular diseases and increase in the role of nephrotoxicity and co-morbidities...

Introduction: Fibrillary glomerulonephritis (FGN) is a rare disease with unknown pathogenesis and a poor prognosis. Until now, the diagnosis of this disease has required demonstration of glomerular deposition of randomly oriented fibrils by electron microscopy that are Congo red negative and stain with antisera to Igs. We recently discovered a novel proteomic tissue biomarker for FGN, namely, DNAJB9. Methods: In this work, we developed DNAJB9 immunohistochemistry and tested its sensitivity and specificity for the diagnosis of FGN...

Idiopathic membranous nephropathy (MN) is an autoimmune-mediated glomerulonephritis and the most common cause of idiopathic nephrotic syndrome in adult humans. A tumor necrosis factor α (TNF-α)-mediated inflammatory response via TNF receptor 1 (TNFR1) and TNFR2 has been proposed as a pathogenic factor. In this study, we assessed the therapeutic response to blocking TNF signaling in experimental MN. Murine MN was induced experimentally by cationic bovine serum albumin (cBSA); phosphate-buffered saline was used in control mice...

BACKGROUND: C3 glomerulopathy (C3G) is a rare, but severe glomerular disease with grim prognosis. The complex pathogenesis is just unfolding, and involves acquired as well as inherited dysregulation of the alternative pathway of the complement cascade. Currently, there is no established therapy. Treatment with the C5 complement inhibitor eculizumab may be a therapeutic option. However, due to rarity of the disease, parameters predicting treatment response remain largely unknown. METHODS: Seven patients with C3G (five with C3 glomerulonephritis and two with dense deposit disease) were treated with eculizumab...

Hepatitis C virus (HCV) infection affects many organs in the body, including the liver, kidneys, skin, joints and others. Although the hepatic manifestation of HCV has been widely studied, the extrahepatic manifestaions of HCV have not been fully appreciated. Studies have shown that patients with HCV have a higher risk of chronic kidney disease and end-stage renal disease, as well as poorer outcomes after kidney transplantation. Given these findings, it is important to screen HCV patients for presence of renal impairement in a timely manner...

BACKGROUND: Despite the development of biomarkers and noninvasive imaging tools, biopsy remains the only method for correctly diagnosing patients with unexplained hematuria, proteinuria and renal failure. Renal biopsy has been performed for several decades in Taiwan; however, a national data registry is still lacking until 2013. METHODS: The Renal Biopsy Registry Committee was established within the Taiwan Society of Nephrology in January 2013. A biopsy registry format, including basic demographic data, baseline clinical features, laboratory data, and clinical and pathological diagnosis was developed...

The pauci-immune crescentic glomerulonephritis (PICGN) is generally associated with small-vessel vasculitis with a few reported cases associated with other autoimmune diseases such as Systemic Lupus Erythematosus (SLE). We present the case of a female 34-year-old patient with acute kidney injury symptoms with indication for renal replacement therapy in the context of clinical SLE diagnosis. A kidney biopsy was conducted and it was found that most glomeruli showed some segmental sclerosis with synechia to the Bowman's capsule...

BACKGROUND: New classification for membranoproliferative glomerulonephritis has been proposed in the literature. The aim of this study was to compare the clinical, biochemical, etiology and renal biopsy findings of these patients grouped by immunofluorescence as proposed by the new classification. METHODS: Patients with renal biopsy-proven membranoproliferative glomerulonephritis unrelated to systemic lupus erythematosus, diagnosed between 1999 and 2014. The patients were divided according to immunofluorescence: Immunoglobulin positive group, C3 positive only and negative immunofluorescence group...

INTRODUCTION: A report on the prevalence of glomerular disease diagnosed via renal biopsy in Salvador, BA, Brazil was published in 1973 and showed a predominance of membranoproliferative glomerulonephritis, which was frequently associated with hepatosplenic schistosomiasis. OBJECTIVE: In this study, we investigate the potential changes in the distribution of glomerular diseases after a period of important epidemiological transition in Brazil. METHODS: Pathology reports of all patients subjected to kidney biopsy from 2003 to 2015 in a referral nephrology service were reviewed...

The anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitides are autoimmune diseases associated with significant morbidity and mortality. They often affect the kidney causing rapidly progressive glomerulonephritis. While signalling by complement anaphylatoxin C5a though the C5a receptor is important in this disease, the role of the anaphylatoxin C3a signalling via the C3a receptor (C3aR) is not known. Using two different murine models of anti-myeloperoxidase (MPO) glomerulonephritis, one mediated by passive transfer of anti-MPO antibodies, the other by cell-mediated immunity, we found that the C3aR did not alter histological disease severity...

In view of the availability of new immunosuppression strategies, the recurrence of allograft glomerulonephritis (GN) are reported to be increasing with time post transplantation. Recent advances in understanding the pathogenesis of the GN recurrent disease provided a better chance to develop new strategies to deal with the GN recurrence. Recurrent GN diseases manifest with a variable course, stubborn behavior, and poor response to therapy. Some types of GN lead to rapid decline of kidney function resulting in a frustrating return to maintenance dialysis...

C3 glomerulonephritis (C3GN) and dense deposit disease comprise the two classes of C3 glomerulopathy. Studies from Europe and Asia have aided our understanding of this recently defined disorder, but whether these data apply to a diverse United States patient population remains unclear. We, therefore, reviewed clinical and histopathological data, including generation of a C3 Glomerulopathy Histologic Index to score biopsy activity and chronicity, to determine predictors of progression to end-stage renal disease (ESRD) and advanced chronic kidney disease (CKD) in 111 patients (approximately 35% non-white) with C3 glomerulopathy: 87 with C3GN and 24 with dense deposit disease...

Severe lupus nephritis in the absence of systemic lupus erythematosus (SLE) is a rare condition with an unclear clinical presentation and outcome.We conducted a historical observational study of 12 adult (age >18 years) patients with biopsy-proven severe lupus nephritis or lupus-like nephritis without SLE immunological markers at diagnosis or during follow-up. Excluded were patients with chronic infections with HIV or hepatitis B or C; patients with a bacterial infectious disease; and patients with pure membranous nephropathy...

Granulomatosis with polyangiitis (GPA) is a small-vessel necrotizing granulomatous vasculitis typically involving upper airways, lungs, and kidneys, which may lead to end-organ damage and life-threatening complications. Major infections during GPA course represent a considerable concern in the management of the disease. Cytomegalovirus (CMV) infection and disease are rare but significant complications in the course of GPA being associated with high morbidity and mortality rates. Colonic perforation due to CMV colitis is exceedingly rare and has so far almost exclusively been documented in HIV, renal transplant, and systemic lupus erythematosus patients...

RATIONALE: Age-related macular degeneration (AMD) is one of the leading causes of blindness among the elderly. Due to its complex etiology, current treatments have been insufficient. Previous studies reveal three systems closely involved in AMD pathogenesis: lipid metabolism, oxidation and inflammation. These systems are also involved in Alzheimer's disease, atherosclerosis and glomerulonephritis. Understanding commonalities of these four diseases may provide insight into AMD etiology...

Goodpasture's syndrome is a triad of anti-glomerular basement membrane (anti-GBM) circulating antibodies, glomerulonephritis and pulmonary hemorrhage. We reported a 65-year-old woman with headaches, asthenia and weight loss. Giant cell arteritis was confirmed by temporal artery biopsy. The patient had associated renal condition with moderate acute renal failure, proteinuria and haematuria. Renal biopsy showed extracapillary glomerulonephritis and linear staining of immunoglobulins G along glomerular basement membrane...
