Recently, a number of reports have described dominant C3 deposits in renal biopsies of patients with infection-related glomerulonephritis (GN). While acute post-infectious GN and membranoproliferative GN are commonly characterized by immune deposits containing C3 and/or C4, the absence of immunoglobulin (Ig) and/or immune complexes at light or electron microscopy is a rather unusual observation. Dominant C3 deposition is believed to result from the alternative pathway of complement activation via the C3bBb "tickover" convertase...

Nodular glomerulosclerosis -as it was originally described by Kimmelstiel and Wilson- is the main pathognomonic lesion of diabetic nephropathy. However, this particular pattern can also be seen in other conditions such as membranoproliferative glomerulonephritis, light or heavy chain deposition disease, amyloidosis, fibrillary and immunotactoid glomerulonephritis and Takayasu's arteritis. History of diabetes as well as other clinical and pathological features are of crucial importance in order to determine the precise cause of nodular glomerulosclerosis...

INTRODUCTION: The possible confounding influence of investigator-related preferences, available histological techniques, and healthcare systems on the frequencies and incidences of primary and secondary nephropathies was evaluated in this long-term observation. MATERIALS AND METHODS: The observation time from 1983 to 2010 was divided in regard to the political regimes: a) prior to and after German reunification: German Democratic Republic (GDR, period 1 from 1983 to 1990)/Federal Republic of Germany (FRG, period 2 from 1990 to 2010); and the two heads of the division of nephrology, b) conductor 1 (1983 - 2006) and conductor 2 (2006 - 2010)...

. INTRODUCTION: The association of hepatitis C virus (HCV), cryoglobulinemia, and membranoproliferative glomerulonephritis (MPGN) is well known. Treatment of underlying HCV infection has greatly improved in recent years with the introduction of direct-acting antivirals (DAA), which have demonstrated curative sustained viral response (SVR) rates for select viral genotypes with the added benefit of less drug side effects. However, a mainstay of newer DAAs is sofosbuvir, which is contraindicated in patients with severe renal impairment...

There is a great lack of efficient treatments for membranoproliferative glomerulonephritis (MPGN) and recently emerged complement therapies have been proposed to be useful. We report a patient with a complement-mediated MPGN having recurrencies in kidney allografts and an unsuccessful treatment with complement inhibitor, eculizumab (anti-C5 monoclonal antibody). Nephritic factor (C3Nef), an autoantibody against C3bBb, in the patient serum activated C3 but not C5 showing that major damage was mediated by C3 activation with clearly less involvement of C5 explaining unresponsiveness to eculizumab...

A 71-year-old male with a past history of lower limb arteriosclerosis obliterans developed nephrotic syndrome and renal dysfunction. Renal biopsy showed diffuse global endocapillary proliferative lesions with infiltration of mononuclear cells and occasional foam cells. An irregular double contour of the glomerular basement membrane and global mild-to-moderate mesangial proliferative lesions were observed, indicating membranoproliferative glomerulonephritis. Congo red staining was negative. Routine immunofluorescence studies showed no obvious immunoglobulin or complement depositions...

Rosai-Dorfman disease is also known as sinus histiocytosis with massive lymphadenopathy. Extranodal Rosai-Dorfman disease has been reported in ~ 43% of cases; the most frequent extranodal sites - skin, soft tissue, bone, respiratory tract, and eye - are usually involved in association with lymphadenopathy. Lack of lymph node involvement is rare, especially when patients manifest renal disease. Here, we describe a patient who developed membranoproliferative glomerulonephritis when lymphadenopathy was absent...

PURPOSE: In this retrospective study with case-control design, we aimed to determine the clinical and pathological characteristics of post-transplant glomerulonephritis (GN), and their effects on transplant recipients. METHODS: One hundred and twenty renal transplant recipients with biopsy-proven recurrent or de novo primary GN were compared with two matched control groups including 120 transplant recipients with nonrecurrent primary GN (nonrecurrent GN group) and 120 transplant recipients with non-GN etiology (non-GN group)...

Membranoproliferative GN (MPGN) was recently reclassified as alternative pathway complement-mediated C3 glomerulopathy (C3G) and immune complex-mediated membranoproliferative GN (IC-MPGN). However, genetic and acquired alternative pathway abnormalities are also observed in IC-MPGN. Here, we explored the presence of distinct disease entities characterized by specific pathophysiologic mechanisms. We performed unsupervised hierarchical clustering, a data-driven statistical approach, on histologic, genetic, and clinical data and data regarding serum/plasma complement parameters from 173 patients with C3G/IC-MPGN...

RATIONALE: TAFRO syndrome is a systemic inflammatory disease characterized by a constellation of symptoms: Thrombocytopenia, Anasarca, MyeloFibrosis, Renal dysfunction, and Organomegaly. Progressive renal insufficiency is a predominant symptom; however, the mechanism of acute kidney injury (AKI) remains unclear, probably because severe thrombocytopenia prevents kidney biopsy. We report a rare case of TAFRO syndrome with histologically confirmed renal involvement. PATIENTS CONCERNS: A 70-year-old man developed fever, anasarca, AKI, thrombocytopenia, and hepatosplenomegaly...

Celiac disease, an inflammatory disease of small bowel caused by sensitivity to dietary gluten and related protein, affects approximately 0.5-1% of the population in the Western world. Extraintestinal symptoms and associated diseases are increasingly recognized including diabetes mellitus type 1, thyroid disease, dermatitis herpetiformis and ataxia. There have also been a number of reports of various types of renal involvement in patients with celiac disease including diabetes nephropathy, IgA nephropathy, membranous nephropathy, membranoproliferative glomerulonephritis, nephrotic syndrome related to malabsorption, oxalate nephropathy, and associations of celiac disease with chronic kidney disease and end-stage kidney disease...

The worldwide re-emergence of secondary syphilis which happened in the last decade, has led to an increase in primary and secondary syphilis cases, along with the presentation of atypical forms. Nevertheless, reports of renal syphilis with mucosal and/or cutaneous manifestations are nowadays increasing. Typically, secondary syphilis infection in adults causes nephrotic syndrome due to a membranous glomerulonephritis. Here, we report a case of a 30-year-old immunocompetent man presenting with skin rash, oral and perianal erosions and nephritic syndrome...

This descriptive and comparative review examines the changing epidemiology, treatment, renal and patient outcome of childhood nephrotic syndrome (NS) in tropical Africa (TpAfr). In the 1960s to 1980s, corticosteroid-resistant non-minimal change disease (nMCD) including quartan malaria nephropathy (QMN) was the dominant renal histopathology type. The overall incidence of NS was 0.35-1.34% of hospital admissions. Median age at onset of NS ranged between 4.0 and 12.0 years while the mean (SD) age range was 5.8 (3...

Immunoglobulin G4 (IgG4)-related disease is an uncommon autoimmune disease that affects multiple organ systems. Renal involvement typically presents as tubulointerstitial nephritis and less commonly as membranous glomerulonephritis. In this case report, we discuss a 68-year-old patient who presented with rapidly progressive glomerulonephritis. His renal biopsy revealed a membranoproliferative pattern of injury with fibrocellular crescents and extensive infiltration of the tubulointerstitium with IgG4-positive plasma cells...

AIMS: Membranoproliferative glomerulonephritis (MPGN) has been reclassified from an electron microscopy to an immunofluorescence (IF) based semi quantitative classification with immunoperoxidase (IP) technique as a backup option when IF is not possible. However, no data are available on the interobserver variability, the correlation and the reclassification of MPGN based on these two techniques. METHODS & RESULTS: We retrospectively analyzed cases of type 1 MPGN...

We aimed to assess the risk of chronic kidney disease (CKD) in chronic hepatitis C virus (HCV) infected patients and the incidence reduction of CKD after receipt of HCV treatment. We also evaluated the risk of membranoproliferative glomerulonephritis (MPGN) and cryoglobulinemia in chronic HCV patients. A retrospective cohort analysis of the Truven Health MarketScan Database (2008-2015) in the United States was conducted. In a cohort of 56,448 HCV-infected patients and propensity score (1:3) matched 169,344 non-HCV patients, we examined the association of HCV infection with the incidence of CKD...

Membranoproliferative glomerulonephritis (MPGN) is a histopathologic diagnosis causing microscopic hematuria, nephrotic range proteinuria, and chronic renal failure. Current understanding divides pathogenesis into two broad categories: immune complex mediated and complement mediated (now termed C3 glomerulopathy). The term idiopathic immune complex-mediated MPGN would apply to a patient without an identifiable source of immune complex production and no evidence of C3 glomerulopathy. Presented is a patient with idiopathic immune complex mediated MPGN and her clinical course...

The spectrum of immune-mediated glomerular diseases is wide, ranging from rare diseases with well-recognized genetic origins to more common and multifactorial diseases. Immune-mediated glomerular injury is complex and involves both the innate and the adaptive immune systems. In the past 20 years a huge effort has been undertaken to unravel the genetic basis of immune-mediated glomerular diseases. The discovery of abnormalities in genes encoding proteins of the alternative pathway of complement in more than 50% of patients with atypical hemolytic uremic syndrome (aHUS), and in approximately 20% of patients with membranoproliferative glomerulonephritis (MPGN), has highlighted the role of this complement pathway in the pathogenesis of immune-mediated glomerular diseases...

Historically, patients with kidney diseases caused by genetic or acquired dysregulation of the complement alternative pathway have been grouped into clinical syndromes, C3 glomerulopathy (C3GN/DDD) and thrombotic microangiopathy (TMA), specifically atypical haemolytic uremic syndrome (aHUS). Recent data suggested that these diseases share a common pathophysiology and that patients can transition between glomerulopathies in this spectrum. Histopathologically, the main difference cited is the immunofluorescence (IF) findings, with C3 predominance in C3 glomerulopathy (compared with immunoglobulins and complements in immune complex-mediated membranoproliferative glomerulonephritis (MPGN)) and negative IF in TMA...
