Renal involvement in Systemic Lupus Erythematous (SLE) patients is one of the leading causes of morbidity and a significant contributor to mortality. It's estimated that nearly 50% of SLE individuals develop kidney disease in the first year of the diagnosis. Class IV lupus nephritis (LN-IV) is the class of lupus nephritis most common in Colombian patients with SLE. Altered miRNAs expression levels have been reported in human autoimmune diseases including lupus. Variations in the expression pattern of peripheral blood circulating miRNAs specific for this class of lupus nephritis could be correlated with the pathophysiological status of this group of individuals...

INTRODUCTION: Systemic lupus erythematosus (SLE) commonly affects women of childbearing age. Hypertension, antiphospholipid syndrome and lupus nephritis are risk factors for adverse maternal/fetal outcome. The aim of this retrospective cohort study is to compare pregnancy outcomes in patients with and without SLE nephritis, using a multidisciplinary approach and a broad prophylaxis protocol. MATERIALS AND METHODS: Data were collected from 86 pregnancies complicated by SLE...

Mycoplasma pneumoniae has been associated with respiratory tract infections. Mycoplasma pneumoniae pneumonia-related pleural effusion is rarely reported. Extra-pulmonary abnormalities such as encephalitis, myocarditis, glomerulonephritis, and myringitis have been reported. However pulmonary manifestations in systemic lupus erythematosus include pneumonitis, pleurisy, interstitial lung disease, and thromboembolic disease. We present the case of a 26-year-old male who came for evaluation of fever, cough, and shortness of breath with right-sided chest pain...

CD64 is a type of integral membrane glycoprotein known as FC receptor that binds monomeric IgG-type antibodies with high affinity. It is more commonly known as FC gamma receptor 1 (FC?R1) and it is expressed on monocytes surface. The goal of this study was to investigate the association of CD64 expression on the surface of peripheral blood monocytes of systemic lupus erythematosus patients with disease activity, and lupus nephritis. 30 SLE patients were enrolled into this study. They were subdivided into: 15 SLE patients with lupus nephritis and 15 SLE patients without lupus nephritis...

PURPOSE OF REVIEW: The purpose of the study was to review the characteristics of renal macrophages and dendritic cells during homeostasis and disease, with a particular focus on lupus nephritis. RECENT FINDINGS: Resident renal macrophages derive from embryonic sources and are long-lived and self-renewing; they are also replaced from the bone marrow with age. The unique characteristics of macrophages in each tissue are imposed by the microenvironment and reinforced by epigenetic modifications...

Induction therapy of proliferative lupus nephritis still requires the use of unselective immunosuppressive drugs with significant toxicities. In search of more specific drugs with equal efficacy but fewer side effects we considered blocking pro-inflammatory chemokine monocyte chemoattractant protein-1 (MCP-1/CCL2) and homeostatic chemokine stromal cell-derived factor-1 (SDF-1/CXCL12), which both contribute to the onset and progression of proliferative lupus nephritis yet through different mechanisms. We hypothesized that dual antagonism could be as potent on lupus nephritis as the unselective immunosuppressant cyclophosphamide (CYC)...

Common DNA sequence variants rarely have a high-risk association with a common disease. When such associations do occur, evolutionary forces must be sought, such as in the association of apolipoprotein L1 (APOL1) gene risk variants with nondiabetic kidney diseases in populations of African ancestry. The variants originated in West Africa and provided pathogenic resistance in the heterozygous state that led to high allele frequencies owing to an adaptive evolutionary selective sweep. However, the homozygous state is disadvantageous and is associated with a markedly increased risk of a spectrum of kidney diseases encompassing hypertension-attributed kidney disease, focal segmental glomerulosclerosis, human immunodeficiency virus nephropathy, sickle cell nephropathy, and progressive lupus nephritis...

Autoantibody-mediated inflammation directed at resident kidney cells mediates lupus nephritis (LN) pathogenesis. This study investigated the role of miRNA in human mesangial cells (HMCs) stimulated with auto anti-dsDNA immunoglobulin (Ig)G antibodies. HMCs were treated with antibodies purified from active LN patients or non-specific IgG controls in the presence of normal serum. Aberrant miRNA was screened using high throughput sequencing. Anti-dsDNA IgG up-regulated 103 miRNAs and down-regulated 30 miRNAs. The miRNAs regulated genes in the cell cycle, catabolic processes, regulation of transcription and apoptosis signalling...

The outcome of lupus nephritis (LN) has changed since the introduction of glucocorticoids (GCs), which dramatically reduced the mortality related to one of the most severe complications of systemic lupus erythematosus (SLE). Since the 1950's, other immunosuppressants, including biologic drugs (i.e. rituximab) have aided in maintaining remission, preserving kidney function, but not preventing treatment-related toxicity. GCs still remain the cornerstone in the treatment of SLE, including LN, and they are widely used in clinical practice...

Lupus nephritis (LN) treatment requires an initial intensive period of therapy followed by a long-term maintenance treatment in order to stabilize disease control and eventually reach renal remission. In this section, Authors discuss the feasibility of safely lowering and even suspending maintenance therapy in LN patients having entered remission, highlighting hurdles in predicting the depth and durability of disease quiescence together with the need for minimizing potentially toxic therapies. Even though no firm conclusions can still be drawn, the treating physician has to find the wise balance between disease control and treatment-related drawbacks by following patients closely and recognizing as early as possible the ones who are likely to reach a deep and durable renal remission; there is consensus that is these are the only patients in whom a potential safe complete withdrawal can be foreseen so far...

Background: Immunosuppression (IS) is the main treatment for most types of glomerulonephritis (GN). Quantifying the cost of IS is necessary to ensure equitable access to therapies and optimal health outcomes, but the real-world cost of IS treatment for GN is largely unknown. We examined temporal changes in the population-level IS medication costs for GN over a 14-year period in a large Canadian province. Methods: We linked a provincial pathology database (containing all GN cases from 2000 to 2012) with renal and medication administrative databases to capture clinical characteristics and IS medications, with follow-up until 2013...

Background: Large-scale studies comparing glomerular disease frequencies across continents are lacking. Methods: We surveyed 29 nephropathology laboratories in four continents using a standardized data collection form. We obtained recent consecutive kidney biopsy diagnosis frequencies at each center and summary demographics for each diagnosis. This report focuses on glomerular disease frequencies by region and race/ethnicity. Results: Among 42 603 glomerular disease diagnoses reported (median age 47 years, 52% male, 57% white), from a total of 60 340 diagnoses, glomerular disease subtype frequencies differed considerably by continent...

Background: Podocytes are terminally differentiated glomerular cells expressing a highly complex architecture and lacking the ability to proliferate. However, during renal injury or stress these cells can re-enter into the cell cycle but fail to divide. As a consequence, bi- and multi-nucleated podocytes can be identified in renal biopsies from patients with various kidney diseases. It is still unclear whether the occurrence of such cells is dependent on or correlates with renal damage and if bi- or multi-nucleation results in ultrastructural alterations such as e...

Lupus nephritis (LN) is a polygenic disease caused by an interaction between hereditary and environmental factors. Numerous gene copy number variations have been identified to contribute to this disease. Previously, immunoglobulin (Ig)G Fcγ receptor 3B (FCGR3B) copy number variation (CNV) was reported to be associated with LN in the Caucasian population. However, the effect of FCGR3B CNV on LN in the Chinese population remains unknown. The present study aimed to investigate whether CNVs of FCGR3B are associated with LN in the Henan Chinese population...

A recent clinical study showed that combination therapy consisting of mycophenolate mofetil, tacrolimus and steroids was shown to be more effective in achieving complete remission in patients with severe forms of lupus nephritis than conventional therapy consisting of intravenous cyclophosphamide and steroids. To explore the underlying molecular and cellular mechanisms of increased efficacy of the combination therapy regimen, we employed a mouse model of lupus nephritis, MRL/lpr mice, and treated them with monotherapies of prednisone, mycophenolate mofetil, or tacrolimus, or with their combination...
