Are Toll-like receptors and decoy receptors involved in the immunopathogenesis of systemic lupus erythematosus and lupus-like syndromes?
2011
In this paper we focus our attention on the role of two families of receptors, Toll-like receptors (TLR) and decoy receptors (DcR) involved in the generation of systemic lupus erythematosus (SLE) and lupus-like syndromes in human and mouse models. To date, these molecules were described in several autoimmune disorders such as rheumatoid arthritis, antiphospholipids syndrome, bowel inflammation, and SLE. Here, we summarize the findings of recent investigations on TLR and DcR and their role in the immunopathogenesis of the SLE.
Optical biosensor-based characterization of anti-double-stranded DNA monoclonal antibodies as possible new standards for laboratory tests.
2009
The serum determination of circulating anti-double-stranded (ds)DNA autoantibodies is a routine measure for the laboratory diagnosis of systemic lupus erythematosus. Since available assays differ substantially and no feasible calibrator is available, the aim of this study was to evaluate a recently introduced surface plasmon resonance (SPR) biosensor chip for binding studies between dsDNA and anti-dsDNA autoantibodies and to demonstrate its usefulness for the characterization of new monoclonal antibody (mAb) standards and standardization of assays. We characterized two human and one murine monoclonal anti-dsDNA antibodies by measuring the kinetic on- and off-rates using the biosensor and ca…
Sunlight exposure exerts immunomodulatory effects to reduce multiple sclerosis severity
2021
AbstractBackgroundMultiple sclerosis (MS) disease risk is associated with reduced sun exposure. This study assessed the relationship between measures of sun-exposure (vitamin D (vitD), latitude) and MS disease severity, the mechanisms of action, and effect-modification by medication and sun-sensitivity associated MC1R variants.MethodsTwo multi-center cohort studies (nNationMS=946, nBIONAT=991). Outcomes were the multiple sclerosis severity score (MSSS) and the number of Gd-enhancing lesion (GELs). RNAseq of four immune cell populations before and after UV-phototherapy of five MS patients.ResultsHigh serum vitD was associated with reduced MSSS (PNationMS=0.021; PBIONAT=0.007) and reduced ris…
Implants in patients with oral manifestations of autoimmune or muco-cutaneous diseases – A systematic review
2018
Background To give an overview on implant survival rates in patients with oral manifestations of systemic autoimmune (oral Lichen planus (oLp), Pemphigus (Pe)), muco-cutaneous (Epidermolysis bullosa (EB)), autoimmune multisystemic rheumatic diseases (Sjögren´s syndrome (SjS), systemic Lupus erythematosus (sLE), or systemic Sclerosis (sSc)). Material and Methods Systematic literature review (PubMed/Medline, Embase) using MESH and search term combinations, published between 1980 and August 2018 in English language reporting on dental implant-prosthetic rehabilitation of patients with oLp, Pe, EB, SjS, sLE, sSc, study design, age, gender, follow-up period (≥ 12 months), implant survival rate. …
Pili Torti: A Feature of Numerous Congenital and Acquired Conditions
2021
Pili torti is a rare condition characterized by the presence of the hair shaft, which is flattened at irregular intervals and twisted 180° along its long axis. It is a form of hair shaft disorder with increased fragility. The condition is classified into inherited and acquired. Inherited forms may be either isolated or associated with numerous genetic diseases or syndromes (e.g., Menkes disease, Björnstad syndrome, Netherton syndrome, and Bazex-Dupré-Christol syndrome). Moreover, pili torti may be a feature of various ectodermal dysplasias (such as Rapp-Hodgkin syndrome and Ankyloblepharon-ectodermal defects-cleft lip/palate syndrome). Acquired pili torti was described in numerous forms of …
COVID‐19 and exacerbation of dermatological diseases: A review of the available literature
2021
Abstract Since the emergence of the new coronavirus disease 19 (COVID‐19) pandemic, there has been a concern for the patients with chronic autoimmune diseases including dermatological conditions over the potential exacerbation of these underlying conditions after infection with severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV2). We performed a systematic review to evaluate presentations, postinfection change in the manifestation, diagnosis, and management of flare‐ups of underlying dermatologic disease in patients with COVID‐19. A total of 17 articles were recovered reporting on flare‐ups of dermatological disease including pemphigus vulgaris, psoriasis, subacute cutaneous lupus er…
Systematic review and meta-analysis of cardiovascular risk in rheumatological disease: Symptomatic and non-symptomatic events in rheumatoid arthritis…
2022
Abstract Although each autoimmune disease is associated with specific tissue or organ damage, rheumatic diseases share a pro-inflammatory pattern that might increase cardiovascular risk. Retrospective and prospective studies on patients affected by systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) highlighted the concept of “accelerated atherosclerosis”. Therefore, the purpose of this systematic review and meta-analysis is the assessment of symptomatic or asymptomatic cardiovascular events among patients with rheumatic diseases as RA and SLE. The literature research obtained all manuscripts published in the English language between 2015 and 2019 for a total of 2355 manuscript…
The skin in autoimmune diseases-Unmet needs.
2016
Treatment of skin manifestations in systemic lupus erythematosus (SLE), systemic sclerosis (SSc), and dermatomyositis (DM) is based on the results of only few randomized controlled trials. The first-line treatment for disfiguring and widespread cutaneous involvement in SLE is antimalarials, but some patients are therapy resistant. Recently, the monoclonal antibody belimumab was approved for SLE as an adjunct therapy for patients with autoantibody-positive disease who despite standard therapy show high disease activity, intolerance of other treatments, or an unacceptably high need for corticosteroids. However, a validated skin score has not been used to confirm the efficacy of belimumab on m…

American College of Rheumatology Provisional Criteria for Clinically Relevant Improvement in Children and Adolescents With Childhood-Onset Systemic L…
2019
OBJECTIVE: To develop a Childhood Lupus Improvement Index (CHILI) as a tool to measure response to therapy in childhood-onset systemic lupus erythematosus (cSLE), with a focus on clinically relevant improvement (CRIc SLE ). METHODS: Pediatric nephrology and rheumatology subspecialists (n = 213) experienced in cSLE management were invited to define CRIc SLE and rate a total of 433 unique patient profiles for the presence/absence of CRIc SLE . Patient profiles included the following cSLE core response variables (CRVs): global assessment of patient well-being (patient-global), physician assessment of cSLE activity (MD-global), disease activity index score (here, we used the Systemic Lupus Eryt…
