INTRODUCTION: Systemic lupus erythematosus is an autoimmune disease in which the severity varies according to race, sex and age of onset. This variation is also observed in the genetic markers associated with the disease, including PTPN22, VDR and TNF genes. The genetic stratification in different populations worldwide can influence the variability. OBJECTIVE: To analyze the heritability of PTPN22, VDR and TNF genetic variants and their association with pediatric lupus nephritis in Colombian families...

BACKGROUND: Approximately 15-20% cases of systemic lupus erythematosus (SLE) are diagnosed in children. There have been a few studies reporting the epidemiological data of pediatric-onset SLE (cSLE) in China, neither comparing the differences between cSLE and adult-onset SLE (aSLE). The aim of this study was to describe the impact of age of onset on clinical features and survival in cSLE patients in China based on the Chinese SLE Treatment and Research group (CSTAR) database. METHODS: We made a prospective study of 225 cSLE patients (aged Results: The mean age of cSLE patients was 12...

BACKGROUND AND AIM: The activity of natural killer (NK) cells is known to be decreased in systemic lupus erythematosus (SLE) patients. Nevertheless, the exact contribution of NK cells in the pathogenesis of SLE is still inconclusive. MicroRNAs (miRNAs), are small noncoding RNA molecules that play a fundamental role in regulating NK cell function. The objective of this study was to investigate the expression of miRNAs that might potentially target an essential activating receptor, NKG2D in peripheral blood mononuclear cells (PBMCs) and NK cells of SLE patients...

OBJECTIVE: The aim of this study was to describe the malignancy rates in childhood and adult-onset systemic lupus erythematous (SLE) by proportional meta-analysis. METHODS: Two reviewers screened data from PubMed (1966-2015), EMBASE (1980-2015), and LILACS (1982-2015) for SLE-associated malignancy. Proportional meta-analysis with a random-effects model and 95% confidence intervals (CIs) were calculated according to SLE onset age and mean follow-up time. Statistical difference was defined by 95% CI overlap...

BACKGROUND/PURPOSE: Despite conventional immunosuppressants, active and steroid-dependent systemic lupus erythematosus (SLE) represents a therapeutic challenge. Only one biologic, belimumab, has been approved, but other biologics are sometimes used off-label. Given the lack of evidence-based data in some clinical situations encountered in real life, we developed expert recommendations for the use of biologics for SLE. METHODS: The recommendations were developed by a formal consensus method...

Objectives Childhood-onset systemic lupus erythematosus (cSLE) is a multisystemic autoimmune disease characterized by inflammatory organ damage by means of vasculitis. Pentraxin-3 (PTX3) is expressed locally at the sites of inflammatory processes, predominantly from endothelial cells. In adult studies, PTX3 has shown to be an indicator of active vasculitis both in large-vessel and small-vessel vasculitides, as well as in SLE. Moreover, in SLE it has found to be correlated with disease activity, and with some of the clinical manifestations and laboratory parameters...

Objectives The carotid intima-media thickness (CIMT) and carotid arterial stiffness index (CASI) act as the surrogate markers of atherosclerosis. We aim to assess CIMT and CASI in pediatric systemic lupus erythematosus (SLE). Methods Patients ≤ 20 years old fulfilling diagnostic criteria for SLE were enrolled. Patients with active smoking, coronary heart disease, cerebrovascular disease, arterial thrombosis, family history of hypercholesterolemia, chronic liver disease, or other chronic severe diseases were excluded...

BACKGROUND: BK virus (BKV) is a ubiquitous polyoma virus that lies dormant in the genitourinary tract once acquired in early childhood. In states of cellular immunodeficiency, the virus can reactivate to cause hemorrhagic cystitis and nephritis. Children with systemic lupus erythematosus (SLE) have an increased risk of developing infectious complications secondary to their immunocompromised state from the administration of several immuno-modulatory drugs. Currently, there are no data regarding the prevalence of BK viruria or viremia in children with SLE...

Objectives Anti-ribosomal P protein (anti-P) autoantibodies are highly specific for systemic lupus erythematosus (SLE). However, the evaluation of this autoantibody in childhood-onset SLE (cSLE) populations has been limited to a few small series, hampering the interpretation of the clinical and laboratorial associations. Therefore, the objective of this multicenter cohort study was to evaluate demographic, clinical/laboratorial features, and disease damage score in cSLE patients with and without the presence of anti-P antibody...

Background Systemic lupus erythematosus (SLE) and antiphospholipid antibody syndrome (APS) are autoimmune diseases that affect women of childbearing age. Maternal IgG antiphospholipid antibodies (aPL) can cross the placenta during pregnancy and theoretically reach the fetal brain. Some studies showed an increased number of learning disabilities in these children. Objectives To evaluate the long-term neurodevelopmental outcome of 40 children (median age 7.4 years) born to mothers with SLE and/or APS carrying positive IgG aPL during the third trimester of pregnancy...

Systemic Lupus Erythematosus (SLE) is a heterogeneous autoimmune disease with heightened disease severity in children. The incomplete understanding of the precise cellular and molecular events that drive disease activity pose a significant hurdle to the development of targeted therapeutic agents. Here, we performed single-cell phenotypic and functional characterization of pediatric SLE patients and healthy controls blood via mass cytometry. We identified a distinct CD14(hi) monocyte cytokine signature, with increased levels of monocyte chemoattractant protein-1 (MCP1), macrophage inflammatory protein-1β (Mip1β), and interleukin-1 receptor antagonist (IL-1RA)...

Childhood-onset systemic lupus erythematosus (cSLE) exhibits an aggressive clinical phenotype and severe complications. This could be due to a pro-inflammatory cytokine milieu. Therefore, we determined plasma levels of Th1 (IL-2, IFN-γ, TNF), Th2 (IL-4), Th17 (IL-17A, IL-6), and Treg (IL-10) cytokines in a cohort of cSLE patients and healthy controls, and we evaluated the association between these cytokines and disease activity. We conducted a cross-sectional study with 51 cSLE patients from two pediatric rheumatology services...

BACKGROUND Bullous pemphigoid is an autoimmune blistering disease, with relapses, isolated or associated with other autoimmune diseases such as systemic lupus erythematosus (SLE). Joint manifestations rapidly respond to small or moderate doses of corticosteroids, whereas skin manifestations usually respond to antimalarial drugs. CASE REPORT We describe the clinical case of an 11-year-old girl with SLE. She showed bullous skin lesions with arthralgia, mild proteinuria, resolved after steroid treatment. At the tapering of her prednisone dose, the patient had new skin lesions requiring an increased dose of prednisone...

REVIEW
Yujuan Zhang, Diana Milojevic
Bone health in children with rheumatic conditions may be compromised due to several factors related to the inflammatory disease state, delayed puberty, altered life style, including decreased physical activities, sun avoidance, suboptimal calcium and vitamin D intake, and medical treatments, mainly glucocorticoids and possibly some disease-modifying anti-rheumatic drugs. Low bone density or even fragility fractures could be asymptomatic; therefore, children with diseases of high inflammatory load, such as systemic onset juvenile idiopathic arthritis, juvenile dermatomyositis, systemic lupus erythematosus, and those requiring chronic glucocorticoids may benefit from routine screening of bone health...
