The gold standard for the classification of lupus nephritis is renal histology but reporting variation exists. The aim of this study was to assess the inter-observer variability of the 2003 International Society of Nephrology/Royal Pathology Society (ISN/RPS) lupus nephritis histological classification criteria in children. Histopathologists from a reference centre and three tertiary paediatric centres independently reviewed digitalized renal histology slides from 55 children with lupus nephritis. Histological ISN/RPS Class was assigned and features scored; lupus nephritis-activity [scored 0-24], lupus nephritis-chronicity [0-12] and tubulointerstitial activity [0-21]...

The diagnosis of Neuropsychiatric systemic lupus erythematosus disease (NPSLE) is challenging. The Automated Neuropsychological Assessment Metrics (ANAM) has been shown to be an accessible and promising tool for evaluating possible NPSLE in adult and childhood lupus. In this review, we present information about the development and use of Ped-ANAM; the benefit of using Ped-ANAM in children with and without NPSLE in the assessment and follow up of their disease condition; and the correlation of Ped-ANAM to imaging studies such as magnetic resonance imaging (MRI)...

The care of children with lupus nephritis (LN) has changed dramatically over the past 50 y. The majority of patients with childhood-onset systemic lupus erythematosus (cSLE) develop LN. In the 1960's, prognosis in children was worse than in adults; therapies were limited and toxic. Nearly half of cases resulted in death within 2 y. Since this time, several diagnostic recommendations and disease-specific indices have been developed to assist physicians caring for patients with LN. Pediatric researchers are validating and adapting these indices and guidelines for the treatment of LN in cSLE...

Systemic lupus erythematosus (SLE) is a multifactorial autoimmune disease with potentially severe clinical manifestation that mainly affects women of child-bearing age. Patients who do not respond to standard-of-care therapies, such as corticosteroids and immunosuppressants, require biologic therapeutics that specifically target a single or multiple SLE pathogenesis pathways. This review summarizes the clinical pharmacokinetic and pharmacodynamic characteristics of biologic agents that are approved, used off-label, or in the active pipeline of drug development for SLE patients...

In this review we critically analyze pulmonary, gastrointestinal and cardiac manifestations of childhood-onset systemic lupus erythematosus (cSLE). Clinical manifestations of these organ systems may be the initial manifestation of cSLE; frequently occur with very active cSLE; and are potential life-threatening manifestations often presenting to the emergency department and requiring admission to the intensive care unit. Early recognition and treatment of the pulmonary, gastrointestinal and cardiac manifestations of cSLE will result in improved prognosis and better outcomes...

BACKGROUND: MicroRNAs (miRNAs) are involved in the post-transcriptional regulation of genes. The objective of this study was to investigate whether select urinary cell-free microRNA's may serve as biomarkers in children with active lupus nephritis (LN) and to assess their relationship to the recently identified combinatorial urine biomarkers, a.k.a. the LN-Panel (neutrophil gelatinase associated lipocalin, monocyte chemotactic protein 1, transferrin, and beta-trace protein). METHODS: miRNAs (125a, 127, 146a, 150 and 155) were measured using real-time polymerase chain reaction in the urine pellet (PEL) and supernatant (SUP) in 14 patients with active LN, 10 patients with active extra-renal lupus, and 10 controls...

Human papilloma virus (HPV) infection is documented to be involved in the development of epithelial malignancies, mostly in cervical cancer. Systemic lupus erythematosus (SLE) patients have an increased prevalence of such an infection. We report the case of a 55-year-old female SLE patient who developed multiple in situ squamous cell carcinomas on her fingers, after chronic HPV infection. HPV-33 DNA was isolated from the lesions. The purpose of this case presentation is to raise awareness about HPV-induced malignancies for this high-risk group and propose an early HPV vaccination to efficiently prevent such comorbidities...

OBJECTIVE: Noninvasive estimation of the degree of inflammation seen on kidney biopsy with lupus nephritis (LN) remains difficult. The objective of this study was to develop a Renal Activity Index for Lupus (RAIL) that, based solely on laboratory measures, accurately reflects histologic LN activity. METHODS: We assayed traditional LN laboratory tests and 16 urine biomarkers (UBMs) in children (n = 47) at the time of kidney biopsy. Histologic LN activity was measured by the National Institutes of Health activity index (NIH-AI) and the tubulointerstitial activity index (TIAI)...

OBJECTIVE: Autoantibodies to the dense fine speckled 70 kDa antigen (DFS70) are reported to be more common in individuals who do not have an antinuclear antibody (ANA)-associated rheumatic disease (AARD) than in patients with AARD. The frequency of anti-DFS70 antibodies has been thoroughly studied in adult but not in pediatric populations. The primary objective of this observational study was to determine the frequency of anti-DFS70 in pediatric AARD and reference cohorts. METHODS: Sera from 743 children with AARD and related conditions, and 345 samples from reference cohorts (healthy children and those being investigated for AARD) were studied for anti-DFS70 autoantibodies as measured by a chemiluminescence immunoassay...

With the increasing use of different types of therapies in treating autoimmune diseases such as systemic lupus erythematosus (SLE), there is a need to utilize pharmacokinetic (PK) strategies to optimize the clinical outcome of these treatments. Various PK analysis approaches, including population PK modeling and physiologically based PK modeling, have been used to evaluate drug PK characteristics and population variability or to predict drug PK profiles in a mechanistic manner. This review outlines the PK modeling of major SLE therapies including immunosuppressants (methotrexate, azathioprine, mycophenolate and cyclophosphamide, among others) and immunomodulators (intravenous immunoglobulin)...

Childhood-onset systemic lupus erythematosus (cSLE) is a systemic autoimmune disease characterized by the presence of autoantibodies. cSLE often affects multiple organs in the body and is known to have a poorer prognosis than adult-onset disease (Azevedo et al. 2014). Current laboratory tests are clearly insufficient for identifying and monitoring the disease. Recent studies have yielded novel biomarkers for cSLE which can be used for monitoring disease activity and response to treatment. The most encouraging biomarkers will be discussed herein and include cell-bound complement activation products, some genomic profiles, and urinary proteins such as neutrophil gelatinase-associated lipocalin, monocyte chemoattractant protein-1, and others...
