S Imtiaz, K Nasir, M F Drohlia, B Salman, A Ahmad
Kidney biopsy occupies a fundamental position in the management of kidney diseases. There are very few renal pathology studies available in the literature from developing world. This study scrutinized the frequency and clinicopathological relationship of kidney biopsies done at the kidney center from 1997 to 2013 amongst pediatric patients. Kidney allograft biopsy were excluded. The specimen was examined under light microscopy and immunofluorescence while electron microscopy was not done. The study includes 423 patients, mean age was 10...

IgG4-related disease (IgG4-RD) is a recently recognized disorder, often with multiple organ involvement, characterized by dense tissue infiltration of IgG4-positive plasma cells, storiform fibrosis, obliterative phlebitis and frequently elevated serum IgG4 concentration. The kidney can be involved either directly or indirectly. The most frequent direct renal manifestations of IgG4-RD are IgG4-related tubulointerstitial nephritis (TIN) and membranous glomerulonephropathy. Retroperitoneal fibrosis (RPF) is another condition that is frequently IgG4-related and that can indirectly affect the kidney causing ureteral obstruction and hydronephrosis...

The present study aims to identify the major active component from mutant Irpex lacteus, which protects against cationic bovine serum albumin (C-BSA)-induced membranous glomerulonephropathy (MGN). The candidate component ILN3A (MW: 2264 kDa) was purified from mutant Irpex lacteus water extract. The backbone of ILN3A comprises (1→2) and (1→4) linkages, and (1)H NMR spectrum suggests the existence of α- and β-glycosidic anomeric carbon. In tissue culture study, ILN3A inhibits mesangial cell proliferation...

IgG4-related disease (IgG4-RD) is a systemic fibroinflammatory condition that involves almost every organ system. In this Review, we summarize current knowledge of IgG4-RD and its most frequent manifestations in the kidney—IgG4-related tubulointerstitial nephritis (TIN) and membranous glomerulonephropathy (MGN). Diagnosis of IgG4-RD relies on histopathology: the typical features are a dense lymphoplasmacytic infiltrate and storiform fibrosis. A high percentage of plasma cells observed within lesions stain positively for IgG4...

The glomerular parietal epithelial cells (PECs) have aroused an increasing attention recently. The proliferation of PECs is the main feature of crescentic glomerulonephritis; besides that, in the past decade, PEC activation has been identified in several types of noninflammatory glomerulonephropathies, such as focal segmental glomerulosclerosis, diabetic glomerulopathy, and membranous nephropathy. The pathogenesis of PEC activation is poorly understood; however, a few studies delicately elucidate the potential mechanisms and signaling pathways implicated in these processes...

We report a 68-year-old Japanese female patient with subepidermal blistering disease with autoantibodies to multiple laminins, who subsequently developed membranous glomerulonephropathy. At skin disease stage, immunofluorescence demonstrated IgG anti-basement membrane zone antibodies reactive with dermal side of NaCl-split skin. Immunoblotting of human dermal extract, purified laminin-332, hemidesmosome-rich fraction and laminin-521 trimer recombinant protein (RP) detected laminin γ-1 and α-3 and γ-2 subunits of laminin-332...

Alport syndrome (AS) is a monogenic disease of the basement membrane (BM), resulting in progressive renal failure due to glomerulonephropathy, variable sensorineural hearing loss, and ocular anomalies. It is caused by mutations in the collagen type IV alpha-3 gene (COL4A3), the collagen type IV alpha-4 gene (COL4A4), and the collagen type IV alpha-5 gene (COL4A5), which encodes type IV collagen α3, α4, and α5 chains, respectively. To explore the disease-related gene in a four-generation Chinese Han pedigree of AS, exome sequencing was conducted on the proband, and a novel deletion mutation c...

Glomerulonephropathy is a rare complication of Takayasu's arteritis (TA). To date, most glomerulonephropathies associated with TA show the histological feature of mesangial proliferation. Membranous glomerulonephropathy (MG) is a form of glomerulonephropathy in which the mesangial proliferation is not conspicuous and its association with TA is extremely rare. A 54-year-old man was referred to our hospital due to progressive edema in the lower limbs and nephrotic range proteinuria. Five years previously, he underwent percutaneous angioplasty for left subclavian artery stenosis...

Membranous glomerulonephropathy can be experimentally induced in rats, but spontaneous cases have been rarely reported. In this report, we present a typical case of spontaneous membranous glomerulonephropathy in a rat. A male Hatano low-avoidance (LAA) strain rat had a tumor mass on the right auricle, and was sacrificed at 41 weeks of age. Urinary screening by reagent strips revealed intense proteinuria. Histological tests revealed frequent presence of irregularly sized eosinophilic hyaline materials on the capillary wall and in the mesangium of renal glomeruli...

The renal glomeruli of 12 male Osborne-Mendel (OM) rats 3 to 24 weeks old were examined by electron microscopy. Effacement of podocyte foot processes (FPs) developed at 3 weeks of age and became progressively worse over time. Loss or dislocation of the slit membrane was also found. Vacuoles and osmiophilic lysosomes appeared in the podocytes starting at 6 weeks of age. Podocyte detachment from the glomerular basement membrane (GBM) was apparent at 18 weeks of age. Laminated GBM was occasionally observed in all animals...

Spontaneous progressive glomerulonephropathy often occurs in common marmosets. However, there are few detailed reports concerning the age-related progressive process of glomerular changes. We discuss the glomerular changes in the early stage and the progressive changes in the advanced stage of nephropathy. We investigated the kidneys of common marmosets (2-11 years old; 9 males and 12 females) using hematoxylin and eosin, periodic acid-Schiff, periodic acid-methenamine-silver, and Masson's trichrome (MT) stains and a transmission electron microscope...

A 68-year-old Japanese woman with asthma of recent onset and a long history of membranous glomerulonephropathy (MN) was admitted because of multifocal pulmonary infiltrates, marked eosinophilia, mild renal dysfunction, a rash on her feet, and right median nerve paralysis. Although MPO- and PR3-ANCA were negative, skin biopsy demonstrated leukocytoclastic vasculitis and Churg-Strauss Syndrome (CSS) was diagnosed. She also had salivary gland swelling and a high serum IgG4 level. Renal biopsy revealed MN with eosinophil-rich tubulointerstitial nephropathy...

BACKGROUND: Given the reported efficacy of mycophenolate mofetil (MMF) in the treatment of glomerular diseases, we question whether MMF can reduce the rate of renal allograft loss due to glomerular disease recurrence compared to azathioprine (AZA) as adjunctive therapy to cyclosporine (CSA)-based immunosuppression. METHODS: This is a retrospective study based on the Organ Procurement and Transplantation Network/United Network for Organ Sharing (OPTN/UNOS) database designed to compare the Kaplan-Meier rates of graft loss due to disease recurrence stratified by primary renal diagnoses between recipients receiving CSA+AZA versus CSA+MMF...

Spontaneous progressive nephropathy dominated by glomerular lesions in common marmosets has been reported. However, the histopathologic characteristics, including the relationship between glomerular and tubulointerstitial lesions, have not been described in detail. In the present study, the authors examined the histopathologic characteristics of the background renal lesions in common marmosets (3 males and 9 females, 3 to 8 years old). The severity of glomerular lesions was graded into 3 classes: grade I, no alteration; grade II, hilar/focal increase of mesangial matrix; grade III, global/diffuse increase of mesangial matrix...

OBJECTIVE: The aim was to assess the level of systemic involvement and character of renal disease in patients with chronic cutaneous lupus erythematosus of the discoid lupus variety (hereafter referred to as 'discoid lupus') and features of systemic lupus erythematosus (SLE). Clinical confusion with other types of cutaneous lupus erythematosus complicates interpretation of some previously reported studies. METHODS: Over three years, sixteen patients met the diagnostic criteria of discoid lupus, positive anti-nuclear-antibody, and at least one extracutaneous manifestation...

Effective detection of potential nephrotoxicity is crucial for pre-clinical drug development. We evaluated a sensitive animal model for drug-induced kidney injury, which includes hemi-nephrectomy of mice. Although bucillamine and d-penicillamine are used for the treatment of rheumatoid arthritis in Japan, drug-related adverse effects on the kidney can limit their therapeutic utilities. When bucillamine (1000 or 2000 mg/kg/day) or d-penicillamine (2000 mg/kg/day) were orally administered to hemi-nephrectomised BALB/c mice, the urinary protein levels of bucillamine-treated mice, but not of those treated with d-penicillamine, the vehicle, or in bucillamine treated unnephrectomized mice, were significantly increased and remained high during the 4-week drug-loading period...

Hepatitis B virus is a well described cause of nephrotic syndrome (NS) worldwide, the typical lesion being membranous glomerulonephropathy. HBV associated NS has been successfully treated with intravenous alpha interferon (IFN), an anti-viral agent. In recent times there have been reports of treatment with lamivudine, an orally administered nucleoside analogue inhibitor of HBV DNA polymerase in Caucasian children. Data is however limited and it's actual efficacy and safety in children is yet to be determined...

A retrospective review of mortality records of Key Largo woodrats (Neotoma floridana smalli) in a captive breeding program revealed chronic renal disease in 5 of 6 woodrats older than 4 years of age. Two of the 5 woodrats with chronic renal disease also had clinical evidence of diabetes mellitus. Kidneys from all 5 woodrats were examined via light microscopy, histochemical staining, immunohistochemical staining, and transmission electron microscopy. The dietary histories of the affected animals were examined as well...

BACKGROUND: Membranous glomerulonephropathy (MN) is the most prevalent cause of nephrotic syndrome in adult humans. However, the specific biomarkers of MN have not been fully elucidated. We examined the alterations in gene expression associated with the development of MN. METHODS: Murine MN was induced by cationic bovine serum albumin (cBSA). After full-blown MN, cDNA microarray analysis was performed to identify gene expression changes, and highly expressed genes were evaluated as markers both in mice and human kidney samples...
