Background: Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease and patients are under an increased risk for cardiovascular (CV) events and mortality. The increased CV risk for patients with SLE seems to be caused by a premature and accelerated atherosclerosis, attributable to lupus-specific risk factors (i.e., increased systemic inflammation, altered immune status), apart from traditional CV risk factors. To date, there is no established experimental model to explore the pathogenesis of this increased CV risk in SLE patients. Methods: Here we investigated whether MRL-Faslpr mice, which develop an SLE-like phenotype, may serve as a model to study lupus-mediated v…
Gut-derived CD8+ tissue-resident memory T cells are expanded in the peripheral blood and synovia of SpA patients
2019
We read with interest the recently published paper from Qaiyum et al 1 demonstrating a novel integrin-expressing mature Crohn's disease (CD)8+ T cell population defined as CD49a+CD103+β7+CD29+ cells in the synovial fluids of ankylosing spondylitis (AS) patients. Although the authors did not analyse gut samples from AS patients, they speculate that these cells might be gut-derived cells. Interestingly, as stated by authors, the transcriptional and phenotypic signature of these cells is reminiscent of human tissue-resident memory T cells (TRM). TRM are a subset of cells important as the first line of defence from infection in mucosal tissues, never studied in spondyloarthritis (SpA).2 For cla…
Secukinumab efficacy in patients with PsA is not dependent on patients' body mass index
2020
We read with interest the recently published paper from McGonagle et al 1 analysing the role of interleukin (IL)-17A in axial spondyloarthritis and psoriatic arthritis (PsA). The meta-analysis and functional study provided by the authors highlighted the efficacy of IL-17A block by secukinumab in the treatment of PsA. However, there is no mention of the role of body mass index (BMI), if any, in influencing the clinical response to secukinumab, given the lack of published data. PsA is a chronic inflammatory arthritis burdened by a series of metabolic comorbidities. Among them, obesity is very common in PsA, with a prevalence of 27%, as confirmed by a recent Spanish work.2 Obesity in PsA has b…
A cyclic peptide significantly improves thyroid function, thyrotropin-receptor antibodies and orbital mucine /collagen content in a long-term Graves’…
2021
BALB/c mice which received long-term immunizations of adenovirus (Ad) expressing thyrotropin receptor A-subunits (TSHR) developed stable Graves' disease (GD). TSHR-derived cyclic peptide 19 (P19) was identified as effective therapy in this model.In Ad-TSHR mice, we investigated shorter disease intervals up to 4 months for histological alterations of the orbits, fine tuning of anti-TSHR antibodies (Ab) and free thyroxine (fT4) hormone levels by using novel detection methods in an independent laboratory. Therapy (0.3 mg/kg P19 or vehicle) was given intravenously after the fourth Ad-TSHR immunization (week 11) and continued until week 19.Thyrotropin binding inhibitory immunoglobulins (TBII, br…
Association between hypovitaminosis D and systemic sclerosis: True or fake?
2016
Abstract Background Vitamin D insufficiency/deficiency is considered a major factor triggering and enhancing several autoimmune disorders; hypovitaminosis D has been reported to be common in Systemic Sclerosis (SSc). Previous studies assessing vitamin D insufficiency/deficiency in SSc have been reviewed, and the relation with pathogenesis and clinical features has been examined. Content Eligibility criteria were: reporting measurement of Vitamin D serum levels in all participants and evaluating adult onset-SSc individuals as patients group. Results: The association between clinical features and low hormone levels is controversial. Manifold data have shown vitamin D insufficiency/deficiency …
AB0492 INTESTINAL MICROBIOTA COMPOSITION OF PATIENT’S WITH BEHCET’S DISEASE: DIFFERENCES BETWEEN EYE, MUCOCUTANEOUS AND VASCULAR INVOLVEMENT (RHEUMA-…
2020
Background:Recently, it has been shown that changes in microbiota composition play a role in the etiology and pathogenesis of chronic diseases. Changes in oral and intestinal microbiota diversity and composition are suggested in Behcet disease (BD), however there are no study available about the potential gut microbiota changes among different clinical forms of BD.Objectives:The aim of this study was to evaluate the intestinal microbiota composition of patient with BD and healthy controls, and also compare BD patients regarding to their eye, mucocutaneous and vascular involvement.Methods:In this prospective cohort study,27 patients diagnosed with BD and 10 aged and sex matched healthy contr…

Biotechnological Agents for Patients With Tumor Necrosis Factor Receptor Associated Periodic Syndrome-Therapeutic Outcome and Predictors of Response:…
2021
Objective: To describe the role of biotechnological therapies in patients with tumor necrosis factor receptor associated periodic syndrome (TRAPS) and to identify any predictor of complete response.Methods: Clinical, laboratory, and therapeutic data from 44 Caucasian TRAPS patients treated with biologic agents were retrospectively collected in 16 Italian tertiary Centers.Results: A total of 55 biological courses with anakinra (n = 26), canakinumab (n = 16), anti-TNF-α agents (n = 10), and tocilizumab (n = 3) were analyzed. A complete response was observed in 41 (74.5%) cases, a partial response in 9 (16.4%) cases and a treatment failure in 5 (9.1%) cases. The frequency of TRAPS exacerbation…
Interstitial lung disease in systemic sclerosis: current and future treatment.
2017
Systemic sclerosis (SSc) has the highest fatality rate among connective tissue diseases and is characterized by vascular damage, inflammation and fibrosis of the skin and various internal organs. Interstitial lung disease (ILD) frequently complicates SSc and can be a debilitating disorder with a poor prognosis. ILD is the most frequent cause of death in SSc, and the management of SScâILD patients is a great challenge. Early detection of pulmonary involvement based on a recent decline of lung function tests and on the extent of lung involvement at high-resolution computed tomography is critical for the best management of these patients. This article summarizes classification, pathogenesis,…

Strongyloides stercoralis (S. stercoralis) is a parasite, endemic in tropical, subtropical, and also not rarely in temperate regions, that infects up to 100 million people worldwide [1]. Patients m...
