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)...

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but life-threatening mucocutaneous diseases. SJS/TEN mostly manifest as a reaction to new drug use, but little is known about their incidence and epidemiology. We conducted a large observational study on the epidemiology of SJS/TEN using data from the UK-based Clinical Practice Research Datalink. Among 551 validated SJS/TEN cases, we calculated an incidence rate of 5.76 SJS/TEN cases/million person-years between 1995 and 2013, which was consistent throughout the study period, and was highest in patients aged 1-10 years and ≥80 years...

Annexin II on mesangial cell surface mediates the binding of anti-dsDNA antibodies and consequent downstream inflammatory and fibrotic processes. We investigated the clinical relevance of circulating annexin II-binding immunoglobulins in patients with severe proliferative lupus nephritis, and renal annexin II expression in relation to progression of nephritis in NZBWF1/J mice. Annexin II-binding immunoglobulins in serum were measured by ELISA. Ultrastructural localization of annexin II was determined by electron microscopy...

Disorders in the regulation of the alternate complement pathway often result in complement-mediated damage to the microvascular endothelium and can be associated with both glomerulonephritis and atypical haemolytic uraemic syndrome. Inherited defects in complement regulatory genes or autoantibodies against complement regulatory proteins are predictive of the severity of the disease and the risk of recurrence post kidney transplantation. Heterozygous mutations in CD46, which codes for a transmembrane cofactor glycoprotein membrane cofactor protein, usually have a lower incidence of end-stage kidney disease and decreased risk of recurrent disease post transplant, as wild-type membrane cofactor protein is present in the transplanted kidney...

BACKGROUND Systemic lupus erythematosus (SLE) leads to renal lesions, which may be clinically silent in patients with little or no proteinuria. Early detection of these lesions may improve prognosis, but early markers are controversial. This study aimed to determine renal marker proteins associated with renal lesion severity in patients with lupus nephropathy (LN) and little or no proteinuria. MATERIAL AND METHODS Patients with LN and little or no proteinuria (<0.5 g/24 hours) (n=187) that underwent kidney biopsy were grouped according to: low severity (Class I or II; n=116) versus high severity (Class III, IV, or V; n=71)...

BACKGROUND: Awareness of the spectrum of clinical manifestations of systemic lupus erythematosus (SLE), especially uncommon changes, is essential for diagnosis and effective management of patients. CASE PRESENTATION: A 26-year-old Chinese man with SLE initially manifested cutaneous papulonodular mucinosis and developed acute Guillain-Barré syndrome and class V lupus nephritis 2 years later. His cutaneous nodules had not been idententified for 2 years and were resected by surgical procedures twice until SLE was diagnosed...

Nearly 20% of SLE corresponds to the pediatric population, and 75% of them have kidney involvement representing an important etiology of chronic kidney disease. A correlation between SLE and ANCA-associated vasculitis has been identified as an overlapping syndrome. Kidney allograft recurrence is rare in SLE when disease control is achieved and with nowadays immunosuppression treatment. Histologic transformation is unusual, especially when there are negative serologic markers and no immune complex deposition reported in native kidneys...

Systemic lupus erythematosus (SLE) is an autoimmune disease with a high prevalence of hypertension. NZBWF1 (SLE-Hyp) mice develop hypertension that can be prevented by modulating T cells. The peptide N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) decreases renal damage and improves renal function in a model of SLE without hypertension (MRL/lpr). However, it is not known whether Ac-SDKP prevents hypertension in NZBWF1 mice. We hypothesized that in SLE-Hyp, Ac-SDKP prevents hypertension and renal damage by modulating T cells...

Systemic lupus erythematosus (SLE) is a multi-organ autoimmune disease characterized by autoantibody production. Mesenchymal stem cells (MSCs) ameliorate SLE symptoms by targeting T cells, whereas the mechanisms of their efficacy remain incompletely understood. In this study, we show that transfer of human MSCs increased MRL.Fas(lpr) mouse survival, decreased T cell infiltration in the kidneys, and reduced T cell cytokine expression. In vitro, allogeneic mouse MSCs inhibited MRL.Fas(lpr) T cell proliferation and cytokine production...

Patients enrolled in the African American Study of Kidney Disease and Hypertension (AASK) Cohort Study who exhibited overt proteinuria have been reported to show high nonalbumin proteinuria (NAP), which is characteristic of a tubulopathy. To determine whether African American Study of Kidney Disease and Hypertension nephropathy (AASK-N) is a tubulopathy, we obtained urine samples of 37 patients with AASK-N, with 24-hour protein-to-creatinine ratios (milligrams per milligram) ranging from 0.2 to 1.0, from the National Institute of Diabetes and Digestive Kidney Diseases repository and tested for seven markers of tubular proteinuria...

(5R)-5-Hydroxytriptolide (LLDT-8), a triptolide derivative with low toxicity, was previously reported to have strong immunosuppressive effects both in vitro and in vivo, but it remains unknown whether LLDT-8 has a therapy effect on systemic lupus erythematosus. In this study, we aimed to investigate the therapeutic effects of LLDT-8 on lupus nephritis in MRL/lpr mice, a model of systemic lupus erythematosus. Compared with vehicle group, different clinical parameters were improved upon LLDT-8 treatment: prolonged life-span of mice, decreased proteinuria, downregulated blood urea nitrogen and serum creatinine, reduced glomerular IgG deposits, and ameliorated histopathology...

Cysteinyl cathepsin K (CatK) is expressed in osteoclasts to mediate bone resorption, but is also inducible under inflammatory conditions. Fas(lpr) mice on a C57BL/6 background develop spontaneous systemic lupus erythematosus-like manifestations. Although normal mouse kidneys expressed negligible CatK, those from Fas(lpr) mice showed elevated CatK expression in the glomeruli and tubulointerstitial space. Fas(lpr) mice also showed elevated serum CatK levels. CatK deficiency in Fas(lpr) mice reduced all tested kidney pathologies, including glomerulus and tubulointerstitial scores, glomerulus complement C3 and IgG deposition, chemokine expression and macrophage infiltration, and serum autoantibodies...

Lysinuric protein intolerance (LPI) is a rare autosomal recessive disease caused by mutations in the SLC7A7 gene encoding the light subunit of a cationic amino acid transporter. Symptoms mimic primary urea cycle defects but dysimmune symptoms are also described. Renal involvement in LPI was first described in the 1980's. In 2007, it appeared that it could concern as much as 75% of LPI patients and could lead to end stage renal disease. The most common feature is proximal tubular dysfunction and nephrocalcinosis but glomerular lesions are also reported...

OBJECTIVES: It's reported that multiple genes in the IFN-γ/STAT1 pathway were hypomethylated and associated with the pathogenesis of lupus nephritis (LN). Our previous study using microarray analysis suggested that interferon induced 35-kDa protein (IFI35) was hypomethylated and increased in LN. However, the role of IFI35 in LN and related mechanism remains to be elucidate. METHODS: The expressions of IFNγR, STAT1, IFI35 and MBD2 in the human kidneys tissues was detected by real-time PCR and western blot...

BACKGROUND: Fibroblast growth factor 23 (FGF23), a phosphate-regulating hormone is an established cardiovascular risk factor. Recently, FGF23 has been related to inflammation. Lupus is an inflammatory disease, and whether FGF23 is associated with Lupus nephritis (LN) activity is unknown. MATERIALS AND METHODS: We studied 15 pre-menopausal patients with recent LN diagnose (⩽2months) and compared them to 1:1 age-matched healthy control group. We measured serum levels of intact FGF23, interleukin-6 (IL-6), tumor necrosis factor α (TNFα), and urinary levels of monocyte chemotactic protein (MCP1)...

OBJECTIVE: Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by extensive immune response including over-activation of T and B cells development of pathogenic autoantibodies, organ damage induced by the formation and deposition of immune complex, and the abnormal elevation of type I interferon. Semaphorin5A (Sema5A), is essentially involved in immune cell regulation and also implicated in the pathogenesis of autoimmune disorders. We aimed to evaluate the role of Sema5A in patients with SLE...

We report here the successful treatment of hepatitis C virus (HCV) transmitted from a nucleic acid testing (NAT)-negative donor to 3 HCV-negative recipients - 2 renal transplants and 1 liver. Both renal recipients underwent standard deceased-donor renal transplantation with immediate graft function. The liver recipient underwent standard orthotopic liver transplantation and recovered uneventfully. The donor was a 39-year-old woman with a terminal serum creatinine of 0.7 mg/dL. She was high risk for bloodborne pathogens, based upon a history of sexual contact with an HCV-infected male partner...

BACKGROUND: Lysinuric protein intolerance (LPI) is a rare metabolic disease resulting from recessive-inherited mutations in the SLC7A7 gene encoding the cationic amino-acids transporter subunit y(+)LAT1. The disease is characterised by protein-rich food intolerance with secondary urea cycle disorder, but symptoms are heterogeneous ranging from infiltrative lung disease, kidney failure to auto-immune complications. This retrospective study of all cases treated at Necker Hospital (Paris, France) since 1977 describes LPI in both children and adults in order to improve therapeutic management...

Non-steroidal anti-inflammatory drugs (NSAIDs) are a broad class of non glucocorticoid drugs which are extensively used in anti-inflammatory, analgesic, and antipyretic therapies. However, NSAIDs may cause many side effects, most commonly in gastrointestinal(GI) tract. Cardiovascular system, kidney, liver, central nervous system and hematopoietic system are also involved. NSAID-induced GI side effects not only endanger the patients' health, increase mortality, but also greatly increase the cost of medical care...
