Lupus nephritis ,renal transplant rejection

Maggie K M Ma, Susan Yung, Tak Mao Chan
Mammalian or mechanistic target of rapamycin (mTOR) is a serine-threonine kinase that plays essential roles in cell growth, proliferation, metabolism, and survival. Increased activation of the mTOR pathway is observed in patients and animal models of renal transplant rejection, autosomal dominant polycystic kidney disease, renal cell carcinoma, diabetic nephropathy, lupus nephritis, and angiomyolipoma. Agents that inhibit mTOR, such as sirolimus and everolimus, are incorporated in immunosuppressive regimens to prevent renal allograft rejection and are often used to facilitate calcineurin inhibitor minimization or to reduce the incidence of tumor recurrence...

Background: Despite being the leading cause of graft failure, there is a lack of published data about the rates of rejection in kidney transplant patients with glomerulonephritis as the cause of end-stage renal disease. Methods: We examined all consecutive adult (>18 years) renal transplant recipients with biopsy-proven native renal glomerular disease who underwent kidney transplant between 1994 and 2013. Glomerulonephritis groups included were IgA nephropathy (IgAN) (N = 306), focal segmental glomerulosclerosis (FSGS) (N = 298), membranous nephropathy (MN) (N = 81), and lupus nephritis (LN) (N = 177)...

Hemodialysis (HD) was first established in Dubai in the year 1980 and was in its full capacity by the year 1983. Since then, the HD population has been growing rapidly. This report represents the demographic data and clinical characteristics of our HD patients during the period between January 2012 and October 2016. Diabetic nephropathy (57%) and hypertension (12.4%) are emerging as the most common causes of end-stage renal disease (ESRD) in our data, followed by undetermined causes in those who presented as ESRD (10...

INTRODUCTION: End-stage renal disease (ESRD) due to lupus nephritis (LN) occurs in 10%-30% of patients. Initially systemic lupus erythematosus (SLE) was a contraindication for kidney transplantation (KT). Today, long-term graft survival remains controversial. Our objective was to compare the survival after KT in patients with SLE or other causes of ESRD. METHODS: All SLE patients who had undergone KT in a retrospective cohort were included. Renal graft survival was compared with that of 50 controls, matched for age, sex, and year of transplantation...

Background Lupus nephritis (LN) is one of the most frequent complications of SLE and occurs in up to 50% of cases depending on the studied population. Of these, approximately 20% progress to end-stage renal disease (ESRD), with the treatment of choice being a kidney transplant. Objective The objective of this study was to describe the clinical outcome of patients transplanted due to LN, compared with patients transplanted for other causes, in a Latin American population from the Fundación Valle del Lili in Cali, Colombia...

Vascular endothelial growth factor A (VEGF-A) is essential for maintaining the glomerular filtration barrier. Absolute renal levels of VEGF-A change in patients with diabetic nephropathy and inflammatory kidney diseases, but whether changes in the renal splicing patterns of VEGF-A play a role remains unclear. In this study, we investigated mRNA splicing patterns of pro-angiogenic isoforms of VEGF-A in glomeruli and whole kidney samples from human patients with kidney disease and from mouse models of kidney disease...

Kidney transplantation after liver transplantation (KALT) offers longer survival and a better quality of life to liver transplantation recipients who develop chronic renal failure. This article aimed to discuss the efficacy and safety of KALT compared with other treatments. The medical records of 5 patients who had undergone KALT were retrospectively studied, together with a literature review of studies. Three of them developed chronic renal failure after liver transplantation because of calcineurin inhibitor (CNI)-induced nephrotoxicity, while the others had lupus nephritis or non-CNI drug-induced nephrotoxicity...

Spleen tyrosine kinase (Syk), a 72 kDa cytoplasmic non-receptor protein-tyrosine kinase, plays an important role in signal transduction in a variety of cell types. Ever since its discovery in the early 1990s, there has been accumulating evidence to suggest a pathogenic role of Syk in various allergic disorders, autoimmune diseases and malignancies. Additionally, there is emerging data from both pre-clinical and clinical studies that Syk is implicated in the pathogenesis of proliferative glomerulonephritis (GN), including anti-glomerular basement membrane disease, anti-neutrophil cytoplasmic antibody-associated GN, lupus nephritis and immunoglobulin A nephropathy (IgAN)...

The presence of tubuloreticular inclusions (TRIs) in native glomerular endothelial cells associates with viral infections and lupus nephritis. However, the associations of TRIs in renal transplant biopsy specimens are not known. We analyzed data from 316 patients who had a transplant biopsy with electron microscopy examination; 41 of 316 (13.0%) patients had TRIs. Patients with TRIs had significantly lower allograft survival rates (50.9%) than patients without TRIs (74.3%; P=0.03). Transplant glomerulopathy-free survival was also inferior in the TRI-positive group (57...

In recent years, mycophenolate mofetil (MMF)-based immunosuppressive regimen was recommended in induction and in maintenance therapy in lupus nephritis (LN), one of the most severe and common manifestations of systemic lupus erythematosus. However, no recommendations were made so far regarding monitoring of mycophenolic acid (MPA) plasma concentrations. Therapeutic drug monitoring (TDM) constitutes a practical tool to ensure optimal posology. In renal transplantation, it was proved that acute allograft rejection incidences decreased when the recommended MPA target exposure has been maintained (30-60 mg·h·L)...

The complement cascade, traditionally considered an effector arm of innate immunity required for host defense against pathogens, is now recognized as a crucial pathogenic mediator of various kidney diseases. Complement components produced by the liver and circulating in the plasma undergo activation through the classical and/or mannose-binding lectin pathways to mediate anti-HLA antibody-initiated kidney transplant rejection and autoantibody-initiated GN, the latter including membranous glomerulopathy, antiglomerular basement membrane disease, and lupus nephritis...

Lupus nephritis (LN) is a severe complication of systemic lupus erythematosus (SLE), associated with high morbidity and mortality. Up to 60% of SLE patients develop LN, and despite novel and potent therapeutic regimens, 5 to 22% develop end-stage renal disease within 15 years of diagnosis. While LN primarily affects younger individuals, it is important to choose optimal method of renal replacement therapy for those who develop end-stage renal disease. Numerous studies were carried out trying to solve problems of treatment of patients with LN...

De novo lupus nephritis (LN) is a rare complication in renal transplantation recipients. We present the clinical manifestations of de novo LN in a 12-year-old boy who received a cadaveric renal transplant. The cause of end-stage renal disease was prune belly syndrome with renal dysplasia. His immunosuppressive drugs included tacrolimus, mycophenolate sodium, and prednisolone. After 3 years of treatment, he developed nephrotic syndrome (NS) without other symptoms of systemic lupus erythematosus (SLE). The renal pathology of the transplanted kidney showed suspicious acute cellular rejection and LN World Health Organization class IV-G (A/C)...

BACKGROUND: Kidney transplantation (KT) has better outcome compared with dialysis in lupus patients. The duration lupus patients need to wait before KT remains debatable, especially in patients with lupus activity. We analyzed a renal transplantation database to elucidate if pretransplantation dialysis (PTD) time and lupus activity affected outcome. METHODS: From 1984 to 2012, 31 Chinese lupus nephritis patients underwent KT at our hospital. The lupus activity was defined as nonrenal systemic lupus erythematosus disease activity index (SLE-DAI) score...

Acute transplant glomerulopathy refers to alloimmune mediated endothelial injury and glomerular inflammation that typically occurs early post-kidney transplantation. We report a case of a 48-year old woman with end stage renal disease from lupus nephritis who developed an unexplained rise in serum creatinine 2 months after renal transplant. As immunosuppression, she received alemtuzumab induction followed by a tacrolimus, mycophenolate mofetil and prednisone maintenance regimen. Her biopsy revealed severe glomerular endothelial injury associated with monocyte/macrophage-rich infiltrate in addition to mild acute tubulointerstitial cellular rejection...

Serum complement cascade, a part of innate immunity required for host protection against invading pathogens, is also a mediator of various forms of disease and injury. It is activated by classical, lectin, and alternative pathways that lead to activation of C3 component by C3 convertases, release of C3b opsonin, C5 conversion and eventually membrane attack complex formation. The tightly regulated activation process yields also C3a and C5a anaphylatoxins, which target a broad spectrum of immune and non-immune cells...

Voclosporin is a novel calcineurin inhibitor intended for prevention of organ graft rejection and treatment of lupus nephritis. These studies evaluated the effect of renal or hepatic impairment on pharmacokinetics of voclosporin. Thirty-three subjects were enrolled into 1 of 4 groups based on renal function as defined by creatinine clearance and 18 subjects were enrolled into 1 of 3 groups based on hepatic function defined by Child-Pugh classes. Voclosporin 0.4 mg/kg was administered orally. Geometric mean ratios (renal/hepatic impairment-to-normal) and 90% confidence intervals for Cmax and AUC were calculated...

Almost all forms of primary as well as secondary glomerulonephritides may recur after renal transplantation. Recurrence of the original disease is now the third most common cause of late allograft loss. Nevertheless, in most cases it is difficult to assess the true impact of primary disease recurrence in the allograft; histological recurrence with mild features does not necessarily implicate clinically severe disease. Moreover it is often difficult to distinguish recurrent from de novo disease as in membranous glomerulopathy...
