BACKGROUND: Recurrence of primary glomerulonephritis in the post-transplant period has been described in the literature but the risk remains poorly quantified and its impact on allograft outcomes and implications for subsequent transplants remain under-examined. Here we describe the rates and timing of post-transplant glomerulonephritis recurrence for IgA nephropathy, focal segmental glomerulosclerosis, mesangiocapillary GN and membranous GN based on 28 years of ANZDATA registry transplant data...

Membranous nephropathy (MN) is a chronic form of glomerulonephritis, associated with the presence of immune complexes beneath the podocytes on the subepithelial region of glomerular capillaries. MN is not a disease entity but one of relatively common patterns of glomerular injury that may be a manifestation of primary renal autoimmunological reaction or may evolve as a phenomenon secondary to wide spectrum of systemic processes.

The most representative kidney lesion of IgG4-related disease (IgG4-RD) is plasma cell-rich tubulointerstitial nephritis (TIN) with distinctive imaging findings including multiple low-density lesions on contrast-enhanced computed tomography. In addition, membranous glomerulonephritis is a representative glomerular lesion of this disease. Recent advances have clarified that inflammation with IgG4-positive plasma cell infiltrates is not restricted to the renal parenchyma, but can be seen in outside the renal capsule, around medium-sized arteries such as lobar arteries, around nerves, and in the renal pelvis and periureter...

BACKGROUND: In glomerular injury dendrin translocates from the slit diaphragm to the podocyte nucleus, inducing apoptosis. We analyzed dendrin expression in IgA glomerulonephritis and Henoch Schönlein purpura (IgAN/HSP) versus in podocytopathies minimal change disease (MCD) and focal segmental glomerulosclerosis (FSGS), and compared it to pathohistological findings and renal function at the time of biopsy and the last follow-up. METHODS: Twenty males and 13 females with median of age 35 years (min-max: 3-76) who underwent percutaneous renal biopsy and had diagnosis of glomerular disease (GD) were included in this retrospective study...

REVIEW
Denver D Brown, Kimberly J Reidy
The causes of macroscopic and microscopic hematuria overlap; both are often caused by urinary tract infections or urethral/bladder irritation. Coexistent hypertension and proteinuria should prompt investigation for glomerular disease. The most common glomerulonephritis in children is postinfectious glomerulonephritis. In most patients, and especially with isolated microscopic hematuria, the diagnostic workup reveals no clear underlying cause. In those cases whereby a diagnosis is made, the most common causes of persistent microscopic hematuria are thin basement membrane nephropathy, immunoglobulin A nephropathy, or idiopathic hypercalciuria...

Eicosanoids are biologically active molecules that are created in the process of oxidation of arachidonic acid (AA) which is a constituent of the cell membrane phospholipids. Throughout the years it was evidenced by experiments that the lipid and lipid-derived metabolites play an important role in physiological and pathological processes in the kidneys. They are being considered as biomarkers in detecting acute kidney injury, nephrotoxicity, glomerulonephritis and early stages of diabetic nephropathy because of their participation in inflammatory processes and in oxidative stress...

Immunofluorescence on frozen tissue is the gold standard immunohistochemical technique for evaluation of immune deposits in the kidney. When frozen tissue is not available or lacks glomeruli, immunofluorescence can be performed on paraffin tissue after antigen retrieval (paraffin immunofluorescence). Excellent results can be obtained by paraffin immunofluorescence in most immune complex-mediated glomerulonephritides and dysproteinemia-associated kidney lesions, and thus this technique has become a valuable salvage technique in renal pathology...

Antiglomerular basement membrane (anti-GBM) disease is a rare but life-threatening autoimmune vasculitis that is characterized by the development of pathogenic autoantibodies to type IV collagen antigens expressed in the glomerular and alveolar basement membranes. Once deposited in tissue, these autoantibodies incite a local capillaritis which manifests as rapidly progressive glomerulonephritis (GN) in 80 to 90% of patients, and with concurrent alveolar hemorrhage in ∼50%. A small proportion of cases may present with pulmonary disease in isolation...

Most patients with anti-glomerular basement membrane (anti-GBM) disease present with rapidly progressive glomerulonephritis with or without pulmonary haemorrhage; however, there are several variants and vigilance is necessary to make a correct diagnosis. Such variants include overlap with anti-neutrophil cytoplasm antibodies-associated vasculitis and membranous nephropathy as well as anti-GBM occurring de novo after renal transplantation. Moreover, patients can present with isolated pulmonary haemorrhage as well as with negative tests for circulating anti-GBM...

Membranous nephropathy is a common cause of nephrotic syndrome in adults and can be primary or secondary through autoimmune disease, medication, infection, or malignancy. Rapidly progressive glomerulonephritis with crescent formation is rare in patients with membranous nephropathy. Thus, in cases with rapid decline in renal function, after excluding complications such as malignant hypertension, acute hypersensitivity interstitial nephritis, and bilateral renal vein thrombosis, the simultaneous occurrence of a superimposed glomerulonephritis should be considered...

Glomerular immunoglobulin A (IgA) deposition is a common finding in hepatic glomerulosclerosis; thus, this disease is also called hepatic IgA nephropathy. However, only a small number of patients with hepatic IgA nephropathy have active glomerular lesions, so functional decline is slow in most cases. In this report, we describe a 60-year-old man who developed nephrotic syndrome and progressive renal impairment during follow-up for alcoholic liver cirrhosis. A renal biopsy showed a membranoproliferative glomerulonephritis-like pattern; diffuse double-contours of the glomerular basement membrane and focal active glomerular lesions with moderate-to-severe endocapillary proliferation and fibrocellular crescents...

BACKGROUND: Chronic kidney disease (CKD) is recognised as a global public health problem, more prevalent in older persons and associated with multiple co-morbidities. Diabetes mellitus and hypertension are common aetiologies for CKD, but IgA glomerulonephritis, membranous glomerulonephritis, lupus nephritis and autosomal dominant polycystic kidney disease are also common causes of CKD. MAIN BODY: Conventional biomarkers for CKD involving the use of estimated glomerular filtration rate (eGFR) derived from four variables (serum creatinine, age, gender and ethnicity) are recommended by clinical guidelines for the evaluation, classification, and stratification of CKD...
