Increased IFN-γ levels have been associated with systemic lupus erythematosus (SLE). However, the relationships among IFN-γ, type I interferons (IFNs) and clinical features have not been extensively studied. Peripheral blood samples from 44 SLE patients and 36 healthy donors (HDs) were collected. Quantitative real-time PCR was used to assess the mRNA expression of IFNG, type II IFN-inducible genes (IRF1, GBP1, CXCL9, CXCL10, and SERPING1, which are used for the type II IFN score), type I IFN-inducible genes (IRF7, MX1, ISG15, and ISG20, which are used for the type I IFN score), TBX21, and EOMES in peripheral blood mononuclear cells...

The systemic autoimmune/inflammatory condition systemic lupus erythematosus (SLE) manifests before the age of 16 years in 10-20% of all cases. Clinical courses are more severe, and organ complications are more common in patients with juvenile SLE. Varying gender distribution in different age groups and increasing severity with younger age and the presence of monogenic disease in early childhood indicate distinct differences in the pathophysiology of juvenile versus adult-onset SLE. Regardless of these differences, classification criteria and treatment options are identical...

Elective neck dissection of the N0-neck is routinely performed during salvage laryngectomy (SLE) for recurrent cancer of the larynx or hypopharynx. The therapeutic benefit of additional neck dissection must be weighed against the risk of increased morbidity. In this retrospective analysis, we assessed oncologic parameters of patients who underwent SLE with concurrent bilateral neck dissection for recurrent laryngeal or hypopharyngeal cancer. We compared these data with patients who underwent primary laryngectomy (LE) with bilateral neck dissection for laryngeal and hypopharyngeal cancer...

Mesenchymal stem cells (MSCs) have been intensively studied and applied in regenerative medicine and tissue engineering. Recently, their immune modulation functions make them as attractive potential approaches for autoimmune disease treatment. Systemic lupus erythematosus (SLE) is one type of chronic autoimmune diseases with multi-organ damaged by the immune system. Although current available treatments are effective for some patients, others are refractory for these therapies. The immuno-modulatory and regenerative characteristics of MSCs make them as one promising candidate for treating SLE...

Systemic lupus erythematosus (SLE) is a common heterogeneous autoimmune disease that is caused by the involvement both of genetic and environmental factors. There is evidence that autophagy is involved in several aspects of SLE pathogenesis. In particular, polymorphisms in the ATG5 gene have been observed to be associated with disease susceptibility. Our aim was to verify if ATG5 polymorphisms are involved in the susceptibility to disease and its clinical phenotypes in an Italian cohort of SLE patients. This study involved 315 SLE patients and 265 healthy controls...

Objectives: Vaccinations are an important measure to prevent infections in immunocompromised patients. The knowledge of vaccination coverage and reasons for non-vaccination in patients with SLE is scarce. The aim of this study was to assess coverage rates of selected vaccinations in a representative sample of SLE patients and to identify predictors for non-vaccination. Methods: In 2013, information on selected vaccinations (coverage, application and reservations) and on demographics, clinical parameters and health beliefs was assessed by means of a self-reported questionnaire among a representative sample of SLE patients in Germany (LuLa cohort)...

Immune Thrombocytopenia (ITP) is an autoimmune disease in which platelet destruction causes thrombocytopenia. Due to the known steroid toxicities, alternative agents have been evaluated for the treatment of these patients. We aimed to review the literature and find evidences regarding the potential benefits of hydroxychloroquine (HCQ) as a steroid-sparing agent in the treatment of ITP. We searched English language articles within Web of Science, PubMed, and Scopus. Cohorts, clinical trials, case reports, conference papers, and letters were included...

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...

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...

REVIEW
Emma Weeding, Amr H Sawalha
Differential deoxyribonucleic acid (DNA) methylation has emerged as a critical feature of systemic lupus erythematosus (SLE). Genome-wide DNA methylation studies have revealed methylation patterns characteristic of SLE-in particular, robust hypomethylation of interferon-regulated genes is a prominent finding in all cells of the immune system studied to date. These patterns reliably distinguish individuals with SLE from healthy controls and from individuals with other autoimmune diseases. For example, hypomethylation within IFI44L is both highly sensitive and highly specific for SLE, superior to currently available biomarkers...

Systemic lupus erythematosus (SLE) has been reported among patients with RASopathy. Five patients have been reported: three with SHOC2 variants, one with a PTPN11 variant, and one with a KRAS variant. SHOC2 variant might represent a relatively common predisposing factor for SLE among the RASopathy genes. However, the clinical details were only reported for two patients, while information on the remaining patient appeared only in a tabular format with minimal clinical description. Here, we report a patient with a SHOC2 variant and SLE...
