A 53-year-old man presented with proteinuria and hematuria. No significant abnormality was detected in his physical examination or laboratory tests, including evidence of paraprotein in serum and urine. Renal biopsy revealed mesangial proliferation, thickened glomerular basement membranes, and spike formation. Immunofluorescence revealed deposition of immunoglobulin (Ig) M heavy chain, kappa (κ) light chain, and complement component C3 along capillary walls in the glomeruli. Light chain staining indicated significant restriction, because only κ chain, not lambda chain, was present in glomeruli...

BACKGROUND: The incidence and age distribution of membranoproliferative glomerulonephritis (MPGN) vary throughout the world by race and ethnicity. We sought to evaluate the clinical features, pathogenesis, and age distribution of MPGN among a large nationwide data from the Japan Renal Biopsy Registry (J-RBR). METHODS: A cross-sectional survey of 593 patients with MPGN (types I and III) registered in the J-RBR between 2007 and 2015 was conducted. Clinical parameters, and laboratory findings at diagnosis were compared between children (< 20 years), adults (20-64 years), and elderly patients (≥ 65 years)...

In 2004, the novel category of monoclonal IgG deposition disease has been proposed and termed "proliferative glomerulonephritis with monoclonal IgG deposits" (PGNMID). This disease is characterized by membranoproliferative glomerulonephritis and staining for a single light-chain isotype and gamma heavy-chain subclass. A 76-year-old male who had monoclonal gammopathy was referred to our hospital because of proteinuria. The renal biopsy showed diffuse thickening of the glomerular capillary walls with focal mesangial proliferation...

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...
