"Rapidly progressive glomerulonephritis"

Various immunity-related adverse events have been reported to be associated with the inhibition of programmed cell death receptor 1. We report a rare case of a relapse of lupus nephritis (LN), involving rapidly progressive glomerulonephritis, which was induced by nivolumab treatment in a patient with oral cancer. The patient had a history of systemic lupus erythematosus and underwent treatment with steroids, rituximab, and plasmapheresis. However, her renal function did not improve, and she died of multiple organ failure...

The clinical spectrum of immunoglobulin A vasculitis nephritis (IgAVN) ranges from the relatively common transitory microscopic hematuria and/or low-grade proteinuria to nephritic or nephrotic syndrome, rapidly progressive glomerulonephritis, or even renal failure. Clinical and experimental studies have shown a multifactor pathogenesis: Infection triggers, impaired glycosylation of IgA1, complement activation, Toll-like-receptor activation and B cell proliferation. This knowledge can identify IgAVN patients at a greater risk for adverse outcome and increase the evidence for treatment recommendations...

A 79-year-old man presented with dyspnea upon exertion, marked renal dysfunction, proteinuria, and hematuria. He was diagnosed with rapidly progressive glomerulonephritis. Serological tests were positive for MPO-ANCA, PR3-ANCA, and anti-GBM antibodies. Since the anti-GBM antibody titer was significantly higher than the ANCA titer and the renal dysfunction was severe, we initially assumed anti-GBM disease and started treatment. Due to poor general condition, a definitive diagnosis could not be made by renal biopsy...

OBJECTIVES: Life-threatening antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) with rapidly progressive glomerulonephritis (RPGN) and/or alveolar haemorrhage (AH) has a poor prognosis. Rituximab (RTX) is as effective as cyclophosphamide (CY) in remission induction therapy; however, the effectiveness and safety of RTX have not been established in life-threatening AAV. This study aimed to investigate the short-term effectiveness and safety of RTX in life-threatening AAV with RPGN and/or AH...

Antiglomerular basement membrane (anti-GBM) disease is a rare, small-vessel vasculitis that affects the capillary beds of the kidneys and lungs. Although exceedingly rare, several case reports have described anti-GBM disease with a concurrent cancer diagnosis, suggesting a possible correlation between these 2 conditions. Herein, we describe the first known case to our knowledge of a woman in her early 60s with simultaneous anti-GBM disease and clear cell renal cell carcinoma, in which the tumor was thought to have been the substrate for anti-GBM disease...

A 69-year-old woman presented with severe anemia, proteinuria, microscopic hematuria and rapidly progressive renal failure. She was admitted to the nephrology department due to severe deterioration of renal function with complaints of malaise, fever, dry cough and occasional epistaxis that appeared 2 months prior to admission. Histopathologic examination of a specimen from kidney biopsy and immunologic findings revealed ANCA positive pauci-immune crescentic glomerulonephritis. The patient had a history of ovarian granulosa cell tumor and lung metastases that were treated surgically with postoperative radiotherapy and chemotherapy...

BACKGROUND: Crescentic glomerulonephritis (CrGN) is a relatively rare but severe condition in childhood with the clinical feature of rapidly progressive glomerulonephritis (RPGN). The aim of this study is to investigate the clinicopathological features and prognosis of CrGN in children. METHODS: We retrospectively analyzed the clinical and laboratory data, renal pathological results, treatment, and outcome of 147 CrGN in two Chinese pediatric nephrology centers...

Anti-GBM disease is a rare, life-threatening small vessel vasculitis caused by circulating anti-GBM antibodies resulting to rapidly progressive glomerulonephritis and/or pulmonary haemorrhage. The gold standard for the diagnosis is the renal biopsy with the pathognomonic finding of linear deposition of IgG along the glomerular capillaries. Early diagnosis and intervention are key determinants of the response to therapy and long-term prognosis of these patients. However, during COVID-19 pandemic recognizing a pulmonary-renal syndrome caused by autoimmune diseases has become challenging...

Glomerulonephritis following an enterococcal endocarditis is an extremely rare and life-threatening condition. We present the case of a 71-year-old patient with rapidly progressive glomerulonephritis following enterococcal endocarditis after surgical replacement of the aortic valve. The combination of antibiotic therapy, corticosteroid therapy and haemodialysis led to an improvement in renal function; however, the severity of cardiac deterioration resulted in a fatal outcome.

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is extremely rare in children. Renal involvement is a common and severe complication of AAV as it can cause end stage kidney disease (ESKD). ANCA renal risk score (ARRS) is helpful in predicting long-term ESKD in patients with ANCA-associated glomerulonephritis (AAGN). This retrospective study included 61 consecutive patients with kidney biopsy specimen-proven AAGN from Clinical Center for Children's Kidney Disease in China. Each patient was assessed by eGFR, normal glomeruli, and tubular atrophy/interstitial fibrosis, and the renal outcome was evaluated using the ARRS...

BACKGROUND: The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been followed by many reports of the development and relapse of autoimmune diseases associated with SARS-CoV-2 vaccination. Some of these reports have involved relapse or onset of immunoglobulin A (IgA) nephropathy following SARS-CoV-2 vaccination. Here, we report on a patient with IgA nephropathy who presented with gross hematuria and rapidly progressive glomerulonephritis following SARS-CoV-2 vaccination...

BACKGROUND: This study aims to investigate the influence of different kidney biopsy practices on the prevalence of glomerular pathologic patterns in the largest kidney biopsy registry in Thailand. METHODS: We conducted a retrospective review of kidney biopsy records from the period between 2000 and 2014. The records were obtained from 2 major institutions: King Chulalongkorn Memorial Hospital, a large university-based hospital, and the Kidney Center Bangkok Hospital, which provides pathology services to hospitals throughout Thailand...

Anti-glomerular basement membrane antibodies are significantly specific for detecting anti-glomerular basement membrane disease. These antibodies are typically targeted against the non-collagenous (NC1) domain of the alpha 3 chain of type IV collagen and, to a lesser extent, the α4(IV) or α5(IV) chains, which create a triple-helical structure in the glomerular basement membrane. The modification of the hexameric structure of NC1 (α3(IV)) results in the exposure of new epitopes, leading to an immune reaction and the subsequent deposition of linear antibodies along the glomerular basement membrane, culminating in crescentic glomerulonephritis...

Anti-glomerular basement membrane (anti-GBM) disease is an acute and life-threatening systemic autoimmune disorder. The coexistence of circulating anti-neutrophil cytoplasmic antibodies (ANCA) and anti-GBM disease, the so-called double-positive disease (DPD), is exceptionally rare. We report a unique case of DPD manifesting as pulmonary-renal syndrome (PRS) in a 46-year-old woman who first presented with clinical and radiological suspicion of pneumonia. Chest computed tomography scan later revealed bilateral alveolar hemorrhage...

Pulmonary renal syndrome (PRS) is a combination of rapid progressive glomerulonephritis (RPGN) and diffuse alveolar hemorrhage (DAH) caused by a variety of immunological and non-immunological etiologies. The difficulty in identifying and reporting seronegative PRS cases could be attributed to the lack of specific immunological markers. Thus, we report a rare case of a 13-year-old boy who was initially diagnosed with idiopathic pauci-immune pulmonary capillaritis (IPIPC). A year later, his condition became complicated, and was referred for further workup...

In patients with kidney disease, nephrotic syndrome can lead to several complications including progressive kidney dysfunction. Proteinuria may lead to the formation of cellular or fibrous crescents with reciprocal development of rapidly progressive glomerulonephritis or focal glomerulosclerosis. Proteinuria may also cause overload and dysfunction of tubular epithelial cells, eventually resulting in tubular atrophy and interstitial fibrosis. Hypoalbuminemia is usually associated with increased risk of mortality and kidney dysfunction...

UNLABELLED: Anti-glomerular basement membrane disease is an extremely uncommon entity in children. It has an incidence of 0.5 to 1 per million per year in adults and is even more uncommon in children. It occurs due to autoantibody against glomerular basement membrane collagen and is characterized by rapidly progressive glomerulonephritis with or without pulmonary hemorrhage. As the literature on anti-glomerular basement membrane disease is limited from our part of the world, it is important to consider it as the rare cause of rapidly progressive glomerulonephritis as early intervention improves prognosis...

Immunoglobulin A (IgA) nephropathy is the most common glomerular disease worldwide. It usually presents as a nephritic syndrome with macroscopic hematuria, oliguria, and proteinuria with or without azotemia. Rapidly progressive glomerulonephritis with crescents is being described in about 30% of cases and is mostly associated with nephrotic-range proteinuria, accelerated hypertension, and accelerated decline toward end-stage renal disease. Medullary angiitis is a rare finding in renal biopsy and is usually associated with pauci-immune glomerulonephritis...
