We describe here the case of a 73-year-old woman who presented a recurrent macular rash, acute respiratory distress, and hemoptysis. Chest CT scan showed diffuse ground-glass opacities that were suggestive of alveolar hemorrhage. With the development of severe acute kidney injury and nephrotic-range proteinuria (creatininemia 2.6 from 1.9 mg/dL with overt proteinuria 34 from 2.1 g/g creat), a kidney-lung syndrome was evoked. Skin biopsy revealed leukocytoclastic vasculitis with IgA deposits. Blood tests showed an increased IgA level...

BACKGROUND: Familial Mediterranean fever is an autosomal recessive disease characterized by recurrent episodes of fever and polyserositis and by the onset of reactive amyloid-associated amyloidosis. Amyloidosis due to familial Mediterranean fever can lead to end-stage renal disease, culminating in kidney transplantation for some patients. In this study, we report the clinical outcome of two brothers with familial Mediterranean fever who were the inadvertent donor and recipient, respectively, of a kidney...

Herein, we report a case of fibrillary glomerulonephritis (FGN). FGN usually shows non-amyloidal fibrils in the mesangium and glomerular capillary walls on electron microscopy. Inherited cases of FGN have been reported in only 3 families, and the suspected genetic form was autosomal dominant. In the present case, the deposition of microfibrils in the arteriolar wall as well as the glomerulus is unique. Our patient's father died of nephrotic syndrome, and his elder brother had a biopsy-proven glomerulopathy...

Paraneoplastic glomerulopathy has been described in established cases of the solid tumors of lung, gastrointestinal system, breast, etc., and rarely in patients with Renal Cell Carcinoma (RCC). Studies on secondary glomerular diseases have described a higher incidence of IgA nephropathy in patients with RCC compared to membranous glomerulopathy, which are commonly reported in malignancies of the lung and gastrointestinal tract. Collecting Duct Carcinoma (CDC), a rare high grade adenocarcinoma accounts for <1% of all renal malignancies...

Background: This is the first report on the epidemiology of biopsy-proven kidney diseases in Poland. Methods: The Polish Registry of Renal Biopsies has collected information on all (n = 9394) native renal biopsies performed in Poland from 2009 to 2014. Patients' clinical data collected at the time of biopsy, and histopathological diagnoses were used for epidemiological and clinicopathologic analysis. Results: There was a gradual increase in the number of native renal biopsies performed per million people (PMP) per year in Poland in 2009-14, starting from 36 PMP in 2009 to 44 PMP in 2014...

BACKGROUND: Histone H3K4 trimethylation (H3K4 me3) is found in active euchromatic regions and plays an important role in podocyte function in which actin filaments are abundant in the foot processes. The pathogenesis of membranous nephropathy (MN), the most prevalent cause of primary nephrotic syndrome in the middle-aged and elderly, is podocyte dysfunction. METHODS: We investigated the role of H3K4 me3 in podocyte dysfunction in nephrotic syndrome using cultured podocytes and a mouse proteinuria model induced by LPS...

BACKGROUND: Idiopathic membranous nephropathy (IMN) is a common cause of nephrotic syndrome (NS) in adults in Western countries. In 2012, the KDIGO (Kidney Disease: Improving Global Outcomes) working group published guidelines for the management of glomerulonephritis, thus providing a template for the treatment of this condition. While being aware of the impact of the clinicians' acumen and that patients may choose a different therapeutic option due to the risks of specific drugs and also of the evolving guidelines, this review details our approach to the management of patients with IMN in a Western center (Toronto)...

BACKGROUND: Membranous nephropathy (MN) is the most common cause of nephrotic syndrome (NS) in adults, accounting for about 20.0% of all NS cases. With an increasing prevalence, especially in the elderly, it has received great attention in Asia. SUMMARY: Recently, the prevalence of idiopathic MN (IMN) has significantly increased among the elderly people in Asia and other places in the world. Although the exact mechanism of IMN remains unveiled, the identification of new antigens such as PLA2R and THSD7A has greatly enhanced our understanding of its pathogenesis...

Amyloidosis is characterized by extracellular deposition of misfolded proteins as insoluble fibrils. Most renal amyloidosis cases are Ig light chain, AA, or leukocyte chemotactic factor 2 amyloidosis, but rare hereditary forms can also involve the kidneys. Here, we describe the case of a 61-year-old woman who presented with nephrotic syndrome and renal impairment. Examination of the renal biopsy specimen revealed amyloidosis with predominant involvement of glomeruli and medullary interstitium. Proteomic analysis of Congo red-positive deposits detected large amounts of the Apo-CII protein...

INTRODUCTION: AA amyloidosis is a common but severe complication of many chronic inflammatory processes of infectious, autoimmune, or neoplastic origin. It frequently leads to renal damage, often presenting as a nephrotic syndrome. Giant cell arteritis is a common inflammatory arteritis in elderly people, but rarely complicated by AA amyloidosis. CASE REPORT: We report an 87-year-old female who presented with a nephrotic syndrome and a chronic inflammation, in whom the kidney biopsy showed secondary amyloidosis...

BACKGROUND: Although the number of patients reaching end-stage kidney disease without a biopsy-proven diagnosis is increasing, the utility of renal biopsy is still an object of debate. We analyzed epidemiological data and the main indications for renal biopsy with a systematic, evidence-based review at current literature. SUMMARY: There is a high discrepancy observed in biopsy rates and in the epidemiology of glomerular diseases worldwide, related to the different time frame of the analyzed reports, lack of data collection, the different reference source population and the heterogeneity of indications...

We herein report the case of an elderly patient with light-chain deposition disease (LCDD) successfully treated with bortezomib. An 83-year-old woman was admitted because of nephrotic syndrome. She was diagnosed to have monoclonal gammopathy of undetermined significance (IgG-κ type) and LCDD, on the basis of serum and urinary immunoelectrophoresis and renal biopsy. She responded to a modified regimen of bortezomib-based chemotherapy with disappearance of proteinuria without any adverse effects. According to a literature review of 16 cases, including the present case, bortezomib-based chemotherapy appears to be a convincing strategy for the treatment of LCDD even in elderly patients...

Primary glomerular diseases in the elderly population are a frustrating topic due to difficulties in both the diagnosis and decision making about treatment. The most frequent type of primary glomerular disease in elderly is membranous nephropathy; while its counterpart in younger population is IgA nephropathy. The most frequent cause of nephrotic syndrome in the elderly is also membranous nephropathy. Pauci-immune crescentic glomerulonephritis (GN) rate increases both in elderly and very elderly population...

INTRODUCTION: Recently, Henoch-Schönlein purpura (HSP) has been observed in elderly people, although it was believed to be uncommon in these subjects. The increased risks of developing end-stage renal disease (ESRD) in adults in comparison with children were highlighted by different studies; however, limited data are available on the treatment of HSP nephritis in adults. METHODS: Between 2002 and 2008, five elderly Japanese patients (>65 years old) (mean age, 68 years, ranging from 65 to 72) with severe forms of HSP nephritis were entered into a prospective study to evaluate prednisolone therapy on the outcome of nephropathy in terms of clinical symptoms and histopathological changes...
