The aim of the present study was to analyze the risk factors for new-onset chronic kidney disease (CKD) in patients who have received a liver transplant. A total of 190 patients who underwent liver transplantation between March 2001 and January 2015 were followed up, and analyzed retrospectively. Sex, age, primary disease, preoperative laboratory findings (hemoglobin, albumin, creatinine and glomerular filtration rate), surgical approach, blood loss during the surgery and transfusion volume, postoperative complications, and the average levels of calcineurin inhibitors (CNIs) (from liver transplantation to the onset of CKD) were analyzed...

Idiopathic membranous nephropathy (MN) is the most common glomerulonephritis in elderly patients showing nephrotic syndrome. However, little is known about its treatment options and outcomes in elderly MN patients at long term follow-up. We retrospectively enrolled patients with biopsy-proven MN between April 1990 and December 2015 from eight tertiary hospitals in Korea. Among them, we excluded patients who had secondary causes of MN and subnephrotic-range proteinuria. We evaluated the presenting features and clinical outcomes and analyzed the all-cause mortality, renal outcomes, infection, and remission with respect to age...

Dense deposit disease (DDD), earlier called Type II membranoproliferative glomerulonephritis is distinct disease having frequent relapses reaching end-stage kidney disease by 10-year in up to 50%-60% of cases and high recurrence rate in the allograft. The term DDD is derived from its distinctive ribbon-like osmiophilic deposits in the lamina densa of glomerular basement membrane by electron microscopy. Pathogenetically, alternate pathway dysfunction leads to this disease, which is diagnosed by ultrastructure...

Suspicion and subsequent detection of renal disease is by an assessment of the urinalysis and renal function in the clinical context. Our attempt in this study is to correlate initial presenting features of urinalysis and renal function to the final histopathological diagnosis. A retrospective analysis of 1059 native kidney biopsies performed from January 2002 to June 2015 at Amrita Institute of Medical Sciences was conducted. Correlative patterns between urinalysis, renal function, and final histopathological diagnosis were studied...

BACKGROUND: Membranoproliferative glomerulonephritis (MPGN) is characterized by mesangial cell proliferation and is classified into types I, II and III based on structural changes in the glomerular capillary walls. The drusen-like deposits of MPGN type II have been studied, but the fundus changes in MPGN type III have yet to be clarified. We report a case of MPGN type III with multiple deposits in the retinal pigment epithelium (RPE). CASE PRESENTATION: A 40-year-old Japanese woman with MPGN type III developed numerous yellow-white patches in the central macula of both eyes...

Factor H related-protein 5 (CFHR5) is a surface-acting complement activator and variations in the CFHR5 gene are linked to CFHR glomerulonephritis. In this study, we show that FHR5 binds to laminin-521, the major constituent of the glomerular basement membrane, and to mesangial laminin-211. Furthermore, we identify malondialdehyde-acetaldehyde (MAA) epitopes, which are exposed on the surface of human necrotic cells ( Homo sapiens ), as new FHR5 ligands. Using a set of novel deletion fragments, we show that FHR5 binds to laminin-521, MAA epitopes, heparin, and human necrotic cells (HUVECs) via the middle region [short consensus repeats (SCRs) 5-7]...

C1q glomerulopathy is a rare variety of chronic glomerulonephritis manifested as C1q deposition revealed by immunofluorescence microscopy. The pathogenesis and etiology of the disease have not been studied. The paper deals with the results of clinical, morphological, immunofluorescence, and electron microscopic examinations in 13 patients with C1q glomerulopathy. Light microscopy more commonly revealed membranous nephropathy, mesangioproliferative glomerulonephritis, and nephrosclerosis. Immunofluorescence microscopy detected a C1q fraction in association with other deposits, more frequently IgM and IgG ones...

As the life expectancy is increasing, there is a rise in elderly population and consequent increase in the patients with renal disease. There is an inconsistency between clinical and histopathological diagnosis in elderly, and so renal biopsy is important in these patients to decide appropriate clinical management and prognosis. This study outlines the importance of renal biopsy in elderly and describes the clinical and pathologic spectrum of renal diseases in patient ≥60 years. All patients (age ≥60 years) undergoing renal biopsies from January 2011 to December 2014 were included in this retrospective study...

Prevalence of different glomerulonephritides and their clinical course vary geographically. Our objectives are to assess the prevalence of different histological types of glomerulonephritis (GN) based on the light microscopic histology and to assess their progression according to histological type. A retrospective cross-sectional study was carried out among adult patients (>18 years) with a histological diagnosis of GN at the University Professorial Unit over a period of six months. Information including demographic data, renal biopsy findings, and progression of the disease through serum creatinine (SCr) level were collected through existing clinic records of consenting patients...

The complement system (CS) has recently been recognized as a bridge between innate and adaptive immunity that constitutes a very complex mechanism controlling the clearance of pathogens, cellular debris, and immune complexes. Out of three known pathways of complement activation, the alternative pathway (AP) plays a critical role in host defense by amplifying the complement response, independently of initiation pathway and continuously maintaining low-level activity in a process called 'thick-over.' A key molecule of the CS is C3, in which the AP is constantly activated...

We report a case of glomerular basement membrane crescentic glomerulonephritis and multicentric Castleman disease-associated interstitial nephritis in a patient with human immunodeficiency virus (HIV) infection. The patient received corticosteroids, cyclophosphamide, and plasmapheresis, and within 3 weeks, there was worsening thrombocytopenia, anemia, and renal function requiring initiation of hemodialysis. He then received 8 weekly doses of rituximab, and there was steady improvement in renal function, such that he stopped dialysis within 6 weeks and has remained in disease remission at 1-year follow-up...

Senescent cells have deleterious effects on the tissue microenvironment through proinflammatory senescence-associated secretory phenotypes; meanwhile, the onset of glomerulonephritis is predominant in younger adults. To clarify the influence of aging on the onset and development of glomerulonephritis, we used a murine model of antibody-mediated nephritis. Sheep nephrotoxic serum was administered in C57BL/6J mice at 12 weeks (adult) or 18 months old (aged) after pre-immunization with sheep IgG. Depositions of sheep IgG and autologous mouse IgG along the glomerular basement membrane and the serum titer of anti-sheep IgG-specific mouse IgG were similar between adult and aged mice...

The association between malignant tumors and the occurrence of glomerular disease has been well documented in previous studies. The most common types of malignant tumor include Hodgkin's lymphoma with minimal change glomerular nephritis, solid tumor with membranous nephropathy and renal cell carcinoma with immunoglobulin (Ig)A nephropathy. The present case study describes a case of a 31-year-old Chinese female patient who was hospitalized with chronic glomerulonephritis. The patient self-administered unknown traditional Chinese medicine; however, protein excretion/24-h remained increased compared with normal levels...

OBJECTIVE: To compare renal function decline, incident end-stage renal disease (ESRD), and mortality among patients with 5 common glomerular diseases in a large diverse population. PATIENTS AND METHODS: A retrospective cohort study (between January 1, 2000, and December 31, 2011) of patients with glomerulonephropathy using the electronic health record of an integrated health system was performed. Estimated glomerular filtration rate (eGFR) change, incident ESRD, and mortality were compared among patients with biopsy-proven focal segmental glomerulosclerosis (FSGS), membranous glomerulonephritis (MN), minimal change disease (MCD), immunoglobulin A nephropathy (IgAN), and lupus nephritis (LN)...

BACKGROUND: The association of increased cancer risk with glomerulonephritis (GN) is well known, but controversy exists concerning which types of GN are involved, and the size of the association. A national registry survey was performed to assess the size of this association, and the temporal relationship of cancer diagnosis to GN diagnosis. METHODS: All patients with biopsy-proven GN between 1985 and 2015 in Denmark were extracted from The Danish Renal Biopsy Registry and the National Pathology Data Bank...

Death of renal cells is central to the pathophysiology of acute tubular necrosis, autoimmunity, necrotizing glomerulonephritis, cystic kidney disease, urosepsis, delayed graft function and transplant rejection. By means of regulated necrosis, immunogenic damage-associated molecular patterns (DAMPs) and highly reactive organelles such as lysosomes, peroxisomes and mitochondria are released from the dying cells, thereby causing an overwhelming immunologic response. The rupture of the plasma membrane exhibits the "point of no return" for the immunogenicity of regulated cell death, explaining why apoptosis, a highly organized cell death subroutine with long-lasting plasma membrane integrity, elicits hardly any immune response...

We had encountered the case of membranous glomerulonephritis (MGN) with dilated cardiomyopathy due to LMNA gene mutation. LMNA mutation was known as a cause of 'laminopathy' such as dilated cardiomyopathy, muscular dystrophy, neuropathy and so on. LMNA gene might be a candidate of genetic basis in cryptogenic MGN.

Idiopathic membranous nephropathy (MN) is an autoimmune-mediated glomerulonephritis and the most common cause of idiopathic nephrotic syndrome in adult humans. A tumor necrosis factor α (TNF-α)-mediated inflammatory response via TNF receptor 1 (TNFR1) and TNFR2 has been proposed as a pathogenic factor. In this study, we assessed the therapeutic response to blocking TNF signaling in experimental MN. Murine MN was induced experimentally by cationic bovine serum albumin (cBSA); phosphate-buffered saline was used in control mice...

Hepatitis C virus (HCV) infection affects many organs in the body, including the liver, kidneys, skin, joints and others. Although the hepatic manifestation of HCV has been widely studied, the extrahepatic manifestaions of HCV have not been fully appreciated. Studies have shown that patients with HCV have a higher risk of chronic kidney disease and end-stage renal disease, as well as poorer outcomes after kidney transplantation. Given these findings, it is important to screen HCV patients for presence of renal impairement in a timely manner...
