Tertiary lymphoid structures (TLS) develop in the kidneys of lupus-prone mice and systemic lupus erythematosus (SLE) patients with lupus nephritis (LN). Here we investigated the presence of mesenchymal stem cells (MSCs) in the development of TLS in murine LN, as well as the role of human MSCs as lymphoid tissue organizer (LTo) cells on the activation of CD4+ T cells from three groups of donors including Healthy, SLE and LN patients. Mesenchymal stem like cells were detected within the pelvic wall and TLS in kidneys of lupus-prone mice...

BACKGROUND: We have previously reported that about 30% of patients affected by a new variant of endemic pemphigus foliaceus (EPF) in El Bagre, Colombia (termed El Bagre-EPF or pemphigus Abreu-Manu) have systemic compromise. In the current study, we focused on studying autoreactivity to the kidney and its pathological correlations. AIM: To investigate patients with El Bagre-EPF for renal compromise. METHODS: We performed a case-control study, enrolling 57 patients with El Bagre-EPF and 57 controls from the endemic area, matched by age, sex, race, work activity, demographics and comorbidities...

In the last few decades, identification of predictors of pregnancy outcome and appropriate pregnancy planning have significantly reduced the maternal and fetal risks in pregnant women with lupus nephritis. Areas covered: Successful pregnancies have been reported even in women with chronic renal disease and renal insufficiency. However, refractory hypertension and severe renal or cardiac chronic dysfunction are still considered contraindications to pregnancy. Pre-term delivery and fetal growth restriction may still occur in SLE patients more frequently than in healthy women, even in pregnancies regularly planned and monitored by a team of nephrologists and gynaecologists...

We report a case of a middle-aged male who presented with pyrexia of unknown origin, oral ulcers, rash and bicytopenia. His past medical history included unexplained proteinuria, infertility and joint pain. Initial workup showed a large retroperitoneal soft tissue mass, which has appeared stable for 10 years. He subsequently developed neuropsychiatric symptoms with imaging findings of meningoencephalitis. Concurrent investigations showed elevated ANA, anti-double-stranded DNA (dsDNA) and ESR levels, as well as low complement levels...

Introduction Lupus nephritis (LN) affects nearly 60% of patients with systemic lupus erythematosus and up to 30% of them will progress to end-stage renal disease (ESRD), despite receiving aggressive immunosuppressive therapy. The prognostic value of ISN/RPS classification is controversial. Therefore, we aimed to identify clinical and pathological predictors of outcome in LN patients independent of this classification. Material and methods Thirty-seven patients with LN who underwent percutaneous kidney biopsy between 1997 and 2016 were included in this study...

Annexin A1 is a protein with multifunctional roles in innate and adaptive immunity mainly devoted to the regulation of inflammatory cells and the resolution of inflammation. Most of the data regarding Annexin A1 roles in immunity derive from cell studies and from mice models lacking Annexin A1 for genetic manipulation (Annexin A1-/- ); only a few studies sought to define how Annexin A1 is involved in human diseases. High levels of anti-Annexin A1 autoantibodies have been reported in systemic lupus erythematosus (SLE), suggesting this protein is implicated in auto-immunity...

Lupus nephritis (LN) is an important cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE) often leading to end-stage renal failure (ESRF) and necessitating renal transplantation (rTp). Optimal timing of rTp in SLE patients with ESRF is uncertain and could potentially affect survival. We investigated the time spent on dialysis before rTp and survival following rTp in a cohort of SLE patients. Retrospective analysis of all adult SLE patients receiving rTp over a 40-year period (1975-2015) in two tertiary UK centres...

BACKGROUND: It has been demonstrated that serum human epididymis protein 4 (HE4) is a useful biomarker for differentiating lupus nephritis (LN) from systemic lupus erythematosus (SLE). However, it remains unclear whether HE4 can be used to predict the development of LN. METHODS: A total of 74 SLE patients without LN were recruited between August 2008 and September 2013. Serum HE4 concentrations were measured by enzyme-linked immunosorbent assay. These patients were followed up from the date of SLE diagnosis to LN development or the end of the study...

Both a lack of biomarkers and relatively ineffective treatments constitute impediments to management of lupus nephritis (LN). Here we used gene expression microarrays to contrast the transcriptomic profiles of active SLE patients with and without LN to identify potential biomarkers for this condition. RNA isolated from whole peripheral blood of active SLE patients was used for transcriptomic profiling and the data analyzed by linear modeling, with corrections for multiple testing. Results were validated in a second cohort of SLE patients, using NanoString technology...

BACKGROUND: Renal involvement is common among Asians with systemic lupus erythematosus and long-term renal outcomes have been described in homogeneous Caucasian and East Asian populations with lupus nephritis but data is scarce for other ethnicities. We aimed to evaluate the incidence and risk factors for progressive chronic kidney disease (CKD) in multi-ethnic South-east Asians with lupus nephritis. METHODS: Single-center retrospective cohort study of adults with biopsy-proven lupus nephritis diagnosed between May 2001 and May 2009...

INTRODUCTION: In contrast to organ transplantation, few studies correlate the monitoring of pp65 antigenemia with a diagnosis of cytomegalovirus (CMV) in patients with systemic lupus erythematosus (SLE). OBJECTIVE: To highlight the importance of CMV outside transplantation, we monitored pp65 antigenemia in a series of SLE patients. METHODS: From March 2015 to March 2016, SLE patients presenting kidney involvement, fever, and an unclear infection at hospital admission were monitored through pp65 antigenemia...

There are national and international clinical practice guidelines for systemic lupus erythematosus treatment. Nonetheless, most of them are not designed for the Mexican population or are devoted only to the treatment of certain disease manifestations, like lupus nephritis, or are designed for some physiological state like pregnancy. The Mexican College of Rheumatology aimed to create clinical practice guidelines that included the majority of the manifestations of systemic lupus erythematosus, and also incorporated guidelines in controversial situations like vaccination and the perioperative period...

Systemic lupus erythematosus (SLE) is an autoimmune chronic inflammatory disease that affects multiple organs and tissues. Lupus nephritis (LN) is a serious complication of SLE, which occurs at a high rate. Conventional treatment strategies of LN have been widely accepted by two concepts such as induction therapy and maintenance therapy. In LN induction therapy until recently, cyclophosphamide in combination with prednisone (PSL) has been the standard method of treatment for proliferative forms of LN. In the latest review, the combination of mycophenolate mofetil (MMF) is also considered a standard treatment option...

BACKGROUND: The clinical outcomes after kidney transplantation (KT) according to the types of glomerulonephritis (GN) as the cause of end-stage renal disease (ESRD) are various, but there are not many studies on this. METHODS: Among 1,253 patients who had KT between November 1982 and January 2017, 183 recipients with biopsy-proven GN as the primary cause of ESRD were enrolled. We analyzed the incidence of recurrent GN and the factors associated with recurrence and graft and patient survivals...

OBJECTIVES: To evaluate changes in demographic, clinical and histological presentation, and prognosis of lupus nephritis (LN) over time. PATIENTS AND METHODS: We studied a multicentre cohort of 499 patients diagnosed with LN from 1970 to 2016. The 46-year follow-up was subdivided into three periods (P): P1 1970-1985, P2 1986-2001 and P3 2002-2016, and patients accordingly grouped based on the year of LN diagnosis. Predictors of patient and renal survival were investigated by univariate and multivariate proportional hazards Cox regression analyses...

Systemic lupus erythematosus (SLE) is an autoimmune disease posing threats to multiple organs in the human body. As a typical manifestation of SLE, lupus nephritis is characterized by a series of pathological changes in glomerulus as well as accumulation of pathogenic autoreactive IgG with complement in the kidney that dramatically disrupts renal functions. Activation-induced deaminase (AID), which governs both somatic hypermutation (SHM) and class-switch recombination (CSR), has been shown to be essential for the regulation of SLE...

Introduction: Randomized controlled trials (RCTs) are considered the gold standard for assessing treatment efficacy. However, sampling bias can affect the generalization of results to routine clinical practice. Here we assessed whether patients with lupus nephritis (LN) seen in routine clinical practice would have satisfied entry criteria to the major published RCTs in LN. Methods: A systematic literature search from January 1974 to May 2015 was carried out, identifying all RCTs investigating LN induction treatment...

Systemic lupus erythematosus (SLE) is a type of autoimmune disease that damages multiple organs, including the heart, joints, liver and kidneys. The main characteristics of SLE are the deposition of circulating autoantibodies; autoantigen complexes in the renal system; and abnormal expression of complements, cytokines and chemokines. Lupus nephritis (LN) is the most serious manifestation of SLE and is characterized by inflammation of the kidney. This review summarizes recent clinical applications of protein biomarkers including autoantibodies, complements, cytokines and chemokines and some new protein biomarkers in SLE and LN...
