OBJECTIVE: Systemic lupus erythematosus (SLE) is a multi-system inflammatory disease characterized by production of various autoantibodies. The aim of this study was to investigate the presence of anti-ficolin-2 antibodies in SLE patients and to evaluate the association between the levels of these autoantibodies, clinical manifestations, and disease activity. METHODS: This is a comparative study using a cohort of 165 SLE patients and 48 healthy subjects. SLE patients were further divided into two groups, with "low disease activity" (SLEDAI score ≤ 4, n = 88) and with "high disease activity" (SLEDAI score > 4, n = 77)...

Because of similarities of the musculoskeletal, central nervous system, and renal manifestations in both diseases, diagnosing systemic lupus erythematosus (SLE) in sickle cell disease (SCD) patients can be difficult to establish. Although Sickle Cell Trait (SCT) is still considered a benign form of SCD, its impact on kidney injury and other renal manifestations is well recognized in the literature. In this case report, we look at the challenges that develop when diagnosing patients with a concurrence of both diseases and the importance of early recognition and treatment of lupus nephritis in SCT patients...

BACKGROUND: Systemic Lupus Erythematosus (SLE) is a multisystem autoimmune disease that disproportionately effects women and children of minorities. Renal involvement (lupus nephritis, or LN) occurs in up to 80% of children with SLE and is a major determinant of poor prognosis. We have developed a non-invasive pediatric Renal Activity Index for Lupus (p-RAIL) that consists of laboratory measures that reflect histologic LN activity. These markers are neutrophil gelatinase associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), monocyte chemotactic protein (MCP-1), adiponectin (APN), ceruloplasmin (CP) and hemopexin (HPX)...

Nephrotic syndrome is defined by a triad of clinical features: oedema, substantial proteinuria (> 3.5 g/24 hours) and hypoalbuminaemia (< 30 g/L). It is often associated with hyperlipidaemia, thromboembolism and an increased risk of infection. Nephrotic syndrome develops following pathological injury to renal glomeruli. This may be a primary problem, with a disease specific to the kidneys, or secondary to a systemic disorder such as diabetes mellitus. The most common cause in children is minimal change glomerulonephritis...

Proteins involved in iron homeostasis have been identified as biomarkers for lupus nephritis, a serious complication of systemic lupus erythematosus (SLE). We tested the hypothesis that renal iron accumulation occurs and contributes to renal injury in SLE. Renal non-heme iron levels were increased in the (New Zealand Black x New Zealand White) F1 (NZB/W) mouse model of lupus nephritis compared with healthy New Zealand White (NZW) mice in an age- and strain-dependent manner. Biodistribution studies revealed increased transferrin-bound iron accumulation in the kidneys of albuminuric NZB/W mice, but no difference in the accumulation of non-transferrin bound iron or ferritin...

Background: The diagnosis of glomerular diseases is based on the evaluation of histological lesions in renal tissue by means of light and electronic microscopy, and immunofluorescence technique. Frozen and archival formalin-fixed paraffin-embedded kidney biopsies represent a stored resource for high-throughput technologies. Transcriptomics makes it possible to study the whole gene-expression profile of cells and tissues in a specific period and/or condition. The results, whether considered alone or integrated with other omics data, could help to improve existing knowledge about the pathogenetic mechanisms of glomerulopathies...

Diabetic kidney disease (DKD) is a common complication of diabetes, which is characterized by albuminuria, impaired glomerular filtration rate or a combination of the two. The aim of the present study was to identify the potential key genes involved in DKD progression and to subsequently investigate the underlying mechanism involved in DKD development. The array data of GSE30528 including 9 DKD and 13 control samples was downloaded from the Gene Expression Omnibus database. The differentially expressed genes (DEGs) in DKD glomerular and tubular kidney biopsy tissues were compared with normal tissues, and were analyzed using the limma package...

Children with systemic lupus erythematosus (SLE) generally undergo a pretreatment kidney biopsy. However, some of these patients, especially those with antiphospholipid syndrome (APS), may experience serious coagulopathic complications. We report herein two cases of paediatric SLE with APS in which, despite normal blood test results, the disparate coagulopathic complications of haemorrhage and embolism developed following a kidney biopsy. Case 1 was, an 8-year-old male in whom, primary APS was initially diagnosed...

Unlike conventional B cells, regulatory B cells exhibit immunosuppressive functions to downregulate inflammation via IL-10 production. However, the molecular mechanism regulating the production of IL-10 is not fully understood. In this study, we report the finding that activation-induced cytidine deaminase (AID) is highly upregulated in the IL-10-competent B cell (B10) cell from Innp5d(fl/fl)Aicda(Cre/+) mice, whereas the 5' inositol phosphatase SHIP-1 is downregulated. Notably, SHIP-1 deficiency in AID(+) B cells leads to a reduction in cell count and impaired IL-10 production by B10 cells...

Objectives: Granzymes (Grs) are serine proteases that eliminate virally infected or tumour cells by inducing apoptosis. GrB has been shown to be associated to the pathophysiology of SLE, whereas the role of the other Grs in SLE remain unknown. Methods: Gr levels were determined in the serum of SLE patients and controls and linked to SLE activity parameters, including the IFN signature. In addition, GrB expression was investigated in LN biopsies and correlated to kidney function parameters and disease severity...

A number of short noncoding microRNAs (miRs) have been demonstrated to be highly expressed in many kidney diseases such as renal cancer and lupus nephritis (LN); however, these results have not been extensively investigated. The aim of the present study was to investigate the expression and function of miR‑198 in LN based on the previous studies. miR‑198 expression level in systemic lupus erythematosus (SLE) patients was determined to determine its clinicopathological significance and effect on glomerular cell proliferation...

Abnormal NKG2D ligand expression has been implicated in the initiation and maintenance of various auto-inflammatory disorders including systemic lupus erythematosus (SLE). This study's goal was to identify the cellular contexts providing NKG2D ligands for stimulation of the immunosuppressive NKG2D(+)CD4 T cell subset that has been implicated in modulating juvenile-onset SLE disease activity. Although previous observations with NKG2D(+)CD4 T cells in healthy individuals pointed towards peripheral B cell and myeloid cell compartments as possible sites of enhanced NKG2DL presence, we found no evidence for a disease-associated increase of NKG2DL-positivity among juvenile-onset SLE B cells and monocytes...

BACKGROUND: Proteinuria is a common finding in children. It may be due to a benign cause, but it can also represent early renal injury. Of children with persistent proteinuria noted in mass urine screening programs, 35% have a urine protein level greater than 100 mg/dl and many of them are associated with many underlying renal diseases. The aim of this study was to identify the etiology and prognosis of persistent proteinuria in children. METHODS: We collected data on urine protein from January 2011 to December 2016 in a tertiary medical center...

There is a high prevalence of hyperuricemia (HUA) in the chronic kidney disease (CKD) population. However, there's a dearth of research on HUA's prevalence, subtypes, early detection, and treatment strategies of HUA in lupus nephritis (LN) patients. The aim of this study is to address these knowledge gaps. LN patients presenting to the Department of Nephrology at Shanghai Rui Jin Hospital from January 2011 to January 2016 were recruited. The effective sample size was derived using the power analysis. The demographic, clinical and laboratory characteristics of the LN patients with HUA were compared with those of patients without HUA...

Cystatin C (CysC) is a protein considered as an excellent marker of renal function, and it has been suggested as an independent predictor of cardiovascular (CV) risk. We evaluated the association of serum CysC with renal function, CV risk factors, inflammation, and subclinical atherosclerosis in Systemic Lupus Erythematosus (SLE) patients. Sixty-one SLE female patients were selected according to estimated glomerular filtration rate (GFR) > 60 ml/min/1.73m(2). Renal function parameters, SLE specific factors, CV risk factors, and inflammatory markers were assessed...

The association of thrombotic microangiopathy (TMA) with systemic lupus erythematosus (SLE) has been described in 0.5 to 10% of cases, and patients present worse outcome. TMA is described as the association of microangiopathic hemolytic anemia, thrombocytopenia, and an organ injury, frequently the kidney. This study describes a successful case of use of eculizumab in a patient with SLE and TMA refractory to standard therapy, and provides a literature review. Case description and search in PubMed and MEDLINE using systemic lupus erythemathous and/or antiphospholipid syndrome (APS) and eculizumab retrieved 15 case reports...
