BACKGROUND: Membranous nephropathy (MN) is the most common cause of nephrotic syndrome in adults. As many clinical cases have reported, it may be associated with hepatitis C virus (HCV) infection. Antiviral therapy can be various. CASE SUMMARY: We report a case of patient with chronic HCV infection and MN, who presented with was proteinuria. He was treated with ledipasvir and sofosbuvir (Harvoni; Gilead Sciences, Foster City, CA) and was found to be virus-free. CONCLUSION: We have reported this case to provide insight into whether Ledipasvir-Sofosbuvir should be administered for HCV-related glomerulonephritis...

BACKGROUND: Whether kidney transplantation rates differ by glomerulonephritis (GN) subtype remains largely unknown. METHODS: Using the US Renal Data System, we identified all adult patients with ESRD attributed to 1 of 6 GN subtypes who initiated dialysis in the US (1996-2013). Patients with diabetic nephropathy (DN) and autosomal-dominant polycystic kidney disease (ADPKD) served as "external" non-GN comparators. Using Cox proportional hazards regression, with death considered a competing risk, we estimated hazard ratios [HRs (95% confidence intervals)] for first kidney transplantation, controlling for year, demographics, comorbidities, socioeconomic factors, and Organ Procurement Organization (OPO)...

BACKGROUND: Suggestion for the management of idiopathic membranous nephropathy (IMN) includes 6 months of observation, followed with steroid plus alkylating agent. However, delayed immunosuppression exposes the kidneys to persistent damage. This study aimed to examine the benefit of early immunosuppression in IMN patients. METHOD: A retrospective study was performed. From 1993 to 2013, 161 IMN patients were enrolled. Patients receiving immunosuppression within 6 months after diagnosis were classified as initial-treatment group, whereas other patients as initial-no-treatment group...

Autoantibodies against the M-type phospholipase A2 receptor (PLA2R) are specific markers for primary membranous nephropathy (MN). Quantification of PLA2R autoantibodies is an important, noninvasive tool that facilitates the diagnosis and monitoring of primary MN. In this report we describe a highly quantitative luciferase immunoprecipitation systems (LIPS) assay for detecting PLA2R autoantibodies. For these studies, a cDNA fragment encoding the first 858 amino acids of PLA2R protein was cloned to generate N-terminal antigen fusion constructs with Gaussia luciferase (Gluc) and Nano luciferase (NanoLuc) reporters...

BACKGROUND: Membranous nephropathy is a common cause of the nephrotic syndrome. Treatment with standard regimens fails to induce complete remission in most patients. We evaluated the efficacy of combination therapy with rituximab, low-dose, oral cyclophosphamide, and an accelerated prednisone taper (RCP) for the treatment of idiopathic membranous nephropathy. METHODS: We analyzed 15 consecutive patients with idiopathic membranous nephropathy treated with RCP at Massachusetts General Hospital...

BACKGROUND: Cocaine is a risk factor for acute kidney injury and chronic kidney disease with progression to end-stage renal disease. Levamisole is an adulterant that is added to cocaine to enhance its euphoric effects. Levamisole-adulterated cocaine (LAC) is associated with the distinct clinical syndromes of agranulocytosis, leukocytoclastic vasculitis, cocaine-induced midline destructive lesions (CIMDL), and ANCA-associated vasculitis (AAV) with pauci-immune necrotizing glomerulonephritis...

The most common causes of renal disease in rheumatoid arthritis (RA) are glomerulonephritis (GN), amyloidosis, tubulo-interstitial nephritis, and drug toxicity. Our aim was to evaluate the clinicopathologic correlation of renal lesions and to assess the course and prognosis of renal disease in patients with RA. We conducted a prospective observational study in all adult patients with RA between July 2010 and June 2015. The total number of patients studied was 90, with a female:male ratio of 2.3:1. Mean follow-up duration was 30 ± 6...

This case report discusses the clinical indication for immunosuppressants in patients with idiopathic membranous nephropathy (IMN). Because this disease occasionally shows spontaneous remission, it is necessary to determine the predictive values for a therapeutic effect in order to provide appropriate treatment. Two distinct cases described herein illustrate the different effects of tolvaptan in responders and non-responders, according to the pre-treatment levels of AQP-2 immunostaining in the samples from renal biopsy and urinary levels of AQP-2 and osmolality, suggesting that these values may be useful predictors of response to tolvaptan in patients with nephrotic IMN...

Idiopathic membranous nephropathy (INM) remains a common cause of the nephrotic syndrome in adults. The autoimmune nature of IMN was clearly delineated in 2009 with the identification of the glomerular-deposited IgG to be a podocyte receptor, phospholipase A2 receptor (PLA2R) in 70% to 75% of cases. This anti-PLA2R autoantibody, predominantly the IgG4 subclass, has been quantitated in serum using an enzyme-linked immunosorbent assay and has been used to aid diagnosis and monitor response to immunosuppressive therapy...

We recently described a case of a Thrombospondin Type-1 Domain containing 7A (THSD7A) associated membranous nephropathy in a female patient who was synchronously suffering from a THSD7A-positive malignancy. We here investigated the role of THSD7A as a new potential tumor antigen by evaluating over 20 000 tissue spots in more than 70 different tumor entities by immunohistochemistry using tissue microarrays. THSD7A expression was highly variable in different neoplasias with differing staining patterns. Both gain and loss of THSD7A expression compared to expression status in non-tumor tissue were linked to tumor-specific markers in the different tumor entities and were of prognostic value...

Idiopathic membranous nephropathy (MN) is associated with HLA; however, the HLA allele involved remains unknown. To identify the HLA risk alleles associated with phospholipase A2 receptor (PLA2R)-related MN in the Chinese population, we sequenced the entire MHC region in DNA samples from 99 patients with PLA2R-related MN, 50 patients with PLA2R-unrelated MN, and 100 healthy subjects. Two HLA risk alleles, HLA-DRB1*15:01 and HLA-DRB3*02:02, independently and strongly associated with an increased risk of PLA2R-related MN...

BACKGROUND: The objective of this study is to determine whether initial steroid therapy is actually effective for the treatment of iMN, and we examined a 40% reduction in estimated glomerular filtration rate (eGFR) and remission rates. METHODS: This was a retrospective study between 1993 and 2013. First, we divided patients with iMN having a urinary protein level of ≥1 g/gCre into two groups: those who had received steroid therapy (Group S1; n = 52) within 6 months of diagnosis and those who had received supportive therapy (Group H1; n = 31)...

BACKGROUND/AIMS: The degree of tubular atrophy and interstitial fibrosis (IFTA) is an important prognostic factor in glomerulonephritis. Imbalance between pro-inflammatory cytokines such as monocyte chemoattractant protein- 1 (MCP-1) and protective cytokines such as epidermal growth factor (EGF) likely determine IFTA severity. In separate studies, elevated MCP-1 and decreased EGF have been shown to be associated with IFTA severity. In this study, we aim to evaluate the predictive value of urinary EGF/MCP-1 ratio compared to each biomarker individually for moderate to severe IFTA in primary glomerulonephritis (GN)...

BACKGROUND: Complete remission (CR) and partial remission (PR) are beneficial to the long-term outcome of patients with idiopathic membranous nephropathy (iMN). However, we are lacking in studies that evaluate the clinical predictors of response to treatment with prednisone plus cyclophosphamide (CP). The objectives of the study are to identify clinical factors that could predict clinical remission or relapse in patients with iMN who were treated with prednisone plus i.v. CP therapy. METHODS: This retrospective study recruited a total of 102 eligible patients diagnosed with biopsy-proven iMN between January 2010 and December 2013 in our center...
