Membranous nephropathy (MN), a type of glomerular nephritis, is one of the most common causes of nephrotic syndrome in adults. Although it is known that melatonin plays a protective role in MN, the role of melatonin receptors in the pathophysiology of MN is unclear. Using an experimental MN model and clinical MN specimens, we studied melatonin receptor expression and found that melatonin receptor 1A (MTNR1A) expression was significantly downregulated in renal tubular epithelial cells. Molecular studies showed that the transcription factor pituitary homeobox-1 (PITX1) promoted MTNR1A expression via direct binding to its promoter...

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...

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...

IgG4-related disease (IgG4-RD) is a newly recognized immune-mediated multisystemic disease characterized by a fibro-inflammatory condition with tissue infiltration of IgG4-positive plasma cells and often associated with elevated serum IgG4 levels. Typical renal involvement of IgG4-RD presents as tubulointerstitial nephritis (TIN), membranous or membranoproliferative nephropathy. We are presenting a case with combined IgG4 membranous nephropathy and TIN, as well as a literature review on pathophysiology, diagnosis and treatment of IgG4-RD...

Aim Phosphatase and tensin homolog deleted on chromosome 10 (PTEN) has been proved to be downregulated in podocytes challenged with high glucose (HG), and knockout of PTEN in podocytes aggravated the progression of diabetic kidney disease (DKD). However, whether podocyte-specific knockin of PTEN protects the kidney against hyperglycemia in vivo remains undefined. Methods The inducible podocyte-specific PTEN knockin (PPKI) mice were generated by crossing newly created transgenic loxP-stop-loxP-PTEN mice with podocin-iCreERT2 mice...

This review will encompass definition, pathogenesis, renal clinical manifestations and treatment of immunoglobulin G4-related diseases (IgG4-RDs). IgG4-RD is a recently recognized clinical entity that often involves multiple organs and is characterized by high levels of serum immunoglobulins G4, dense infiltration of IgG4+ cells and storiform fibrosis. Cellular immunity, particularly T-cell mediated immunity, has been implicated in the pathogenesis of IgG4-RDs. The most frequent renal manifestations of IgG4-RD are IgG4-related tubulointerstitial nephritis, membranous glomerulopathy and obstructive nephropathy secondary to urinary tract obstruction due to IgG4-related retroperitoneal fibrosis...

Galactose-deficient IgA1 has been proposed as an important effector molecule in IgA nephropathy (IgAN). We previously showed that the galactose-deficient IgA1-specific monoclonal antibody KM55 can detect circulating galactose-deficient IgA1 in patients with IgAN, enabling us to study the molecular roles of galactose-deficient IgA1. Herein, we further examined the pathophysiological significance of galactose-deficient IgA1 in glomerular deposits of patients with IgAN by immunohistochemistry using KM55. Immunostaining of galactose-deficient IgA1 with KM55 was performed in paraffin-embedded sections of renal biopsy specimens from 48 patients with IgAN and 49 patients with other renal diseases such as lupus nephritis, HCV-related nephropathy, IgA vasculitis with nephritis (IgA-VN), and membranous nephropathy...

AIMS: Nephrotic syndrome (NS) is a major manifestation of lupus nephritis (LN). The dysregulation of podocyte, glomerular basement membrane (GBM) and endothelial cell (EC) develops proteinuria in glomerular diseases. The aim of our study is to clarify whether the dysregulation of these barriers is associated with NS in proliferative LN and membranous LN. METHODS AND RESULTS: Fifty six patients with NS including minimal change NS in 15, primary membranous nephropathy (PMN) in 13, Class III/IV LN in 15 and Class V LN in 13 were enrolled in this study...

Objective: Two recent important lupus nephritis trials reported that proteinuria was a good predictor of renal outcome in Caucasians, but data on real-life situation, other races and severe nephritis are lacking to substantiate this finding as a simple test to guide clinical practice. The aim of this study was to validate proteinuria as a predictor of long-term renal outcome in real-life situation in a racially diverse group of patients with severe nephritis. Methods: Proteinuria, serum creatinine (SCr) and urine red blood cells were assessed at baseline and after 3, 6 and 12 months, as early predictors of long-term renal outcome (SCr <1...
