IgG4-related disease (IgG4-RD) is a recently recognized disorder, characterized by elevated serum IgG4 concentrations, dense tissue infiltration of IgG4-positive plasma cells and storiform fibrosis. Treatment is usually based on steroids, however, relapses and long-term adverse effects are frequent. We prospectively studied 5 consecutive patients with histologically-proven IgG4-RD and renal involvement, treated with an extended Rituximab protocol combined with steroids. Two doses of intravenous cyclophosphamide were added in 4 patients...

Tubulointerstitial nephritis and uveitis (TINU) is a rare syndrome in which idiopathic interstitial nephritis coexists with chronic recurrent uveitis. This syndrome often represents systemic disorders such as arthralgia, rash, prolonged fever, anaemia and ocular symptoms that require medication including glucocorticoid administration. Recently, novel urinary biomarkers, such as kidney injury molecule-1, neutrophil gelatinase-associated lipocalin and liver-type fatty acid-binding protein, were shown to be associated with tubulointerstitial damage and were elevated in interstitial nephritis...

Introduction Lupus nephritis (LN) affects nearly 60% of patients with systemic lupus erythematosus and up to 30% of them will progress to end-stage renal disease (ESRD), despite receiving aggressive immunosuppressive therapy. The prognostic value of ISN/RPS classification is controversial. Therefore, we aimed to identify clinical and pathological predictors of outcome in LN patients independent of this classification. Material and methods Thirty-seven patients with LN who underwent percutaneous kidney biopsy between 1997 and 2016 were included in this study...

A 61-year-old woman was admitted to our hospital because of muscle paralysis and was found to have severe hypokalemia. A gallium-67 scintigram revealed a positive accumulation in the bilateral salivary glands, and a labial minor salivary gland biopsy demonstrated a massive lymphocyte infiltrate around the salivary ducts. She was diagnosed with Sjögren's syndrome (SS) associated with renal tubular acidosis. Renal biopsy revealed tubulointerstitial nephritis with a mild focal infiltration of lymphocytes and plasma cells...

Osteopontin (OPN) is a pro-and ant-inflammatory molecule that simultaneously attenuates oxidative stress. Both inflammation and oxidative stress play a role in the pathogenesis of glomerulonephritis and in the progression of kidney injury. Importantly, OPN is highly induced in nephritic kidney. To further characterize the role of OPN in kidney injury we used OPN-/- mice in anti-glomerular basement membrane reactive serum-induced immune nephritis (NTS), an inflammatory and progressive model of kidney disease...

A 58-year-old man with type 1 autoimmune pancreatitis was referred to nephrologists for severe proteinuria. Laboratory data revealed a high serum IgG4 level, hypoalbuminemia, and massive proteinuria, which were compatible with nephrotic syndrome. The renal pathological findings confirmed the diagnosis of secondary membranous nephropathy concurrent with IgG4-related tubulointerstitial nephritis. Despite the improvement of interstitial markers, the proteinuria was refractory to prednisolone, requiring cyclosporine to achieve complete remission...

Primary Sjögren's syndrome (pSS) is a chronic autoimmune disease characterized by lymphoplasmacytic infiltration of the exocrine glands that results in multiple organs and systems damage. Renal injury affects 0.3%-27.0% patients. The most frequent form of nephropathy in pSS is tubulointerstitial nephritis. The main clinical manifestation is renal tubular acidosis. The renal prognosis in patients with pSS is usually favorable, but renal failure may occur. At present, it still lacks of strict consensus or guideline for the treatment...

Infection-related glomerulonephritis (IRGN) is rarely complicated with eosinophil infiltration into the glomerulus. Here we report a case of eosinophilic proliferative glomerulonephritis related with infection. A 70-year-old man with respiratory symptoms displayed hypereosinophilia, hypocomplementemia, impaired renal function, and nephrotic syndrome. Renal biopsy revealed endocapillary proliferative glomerulonephritis with immunostaining for immunoglobulin G and complement 3, and subepithelial hump-like electron-dense deposits, thus fulfilling the criteria for IRGN...

Autoimmune diseases are sometimes associated with immune-mediated renal diseases and cryoglobulinemia is one of the causes. Cryoglobulinemia and cryoglobulinemic glomerulonephritis associated with primary Sjögren's syndrome are most frequent condition among non-hepatitis C virus-related condition. Its typical renal manifestation shows high amount of proteinuria with microscopic hematuria and renal insufficiency. We describe a case of 72-year-old woman with Hashimoto disease, autoimmune hepatitis, Sjögren's syndrome, and immune-related pancytopenia complicated by cryoglobulinemic glomerulonephritis...

IgG4-related disease is a relatively newly described entity that can affect nearly any organ, including the kidneys, where it usually manifests as tubulointerstitial nephritis (IgG4-TIN). The diagnosis can be suggested by characteristic histological features, including an inflammatory infiltrate with increased IgG4-positive plasma cells associated with "storiform" fibrosis. Serum IgG4 is usually elevated. In the native kidney and other organs, there is typically a brisk response to treatment with immunosuppression...

Collapsing focal segmental glomerulosclerosis (FSGS) is a variant of FSGS and is associated with severe nephrotic syndrome and acute kidney injury and can occur after kidney transplantation. The exact mechanism of collapsing FSGS after kidney transplantation is unknown, but potential causes include autoimmune diseases, certain malignancies, bisphosphonates, m-TOR inhibitors, interferon-alpha, HIV infection, and other viruses. We describe a case of de novo Cytomegalovirus (CMV)-associated collapsing FSGS in a kidney transplant recipient with a UL97 phosphotransferase mutation that was successfully treated with intravenous ganciclovir, intravenous immunoglobulin, and steroids...

BACKGROUND: Renal disease is considered the main cause of natural mortality in dogs with canine leishmaniosis. The pathological mechanisms associated with kidney injury in canine leishmaniosis include immune complex glomerulonephritis, tubulointerstitial nephritis and occasionally renal amyloidosis. Proteinuria is a frequent finding in canine leishmaniosis and its quantification by the urine protein-creatinine ratio (UPC) is an important parameter in the staging of canine lesihmaniosis as presented by the LeishVet group...

INTRODUCTION: Acute tubulointerstitial nephritis (ATIN) is a rare entity in the pediatric age. It is de fined by the infiltration of the renal parenchyma by mononuclear and/or polynuclear cells with se condary involvement of the tubules, without glomerular injury. It can be triggered by infections or immunological diseases, drugs like NSAIDs or be of idiopathic origin. OBJECTIVE: To raise awareness among pediatricians about the prescription of NSAIDs, especially to patients of less than a year old, since they can provoke renal damage...
