Long-term anti-tumour necrosis factor therapy reverses the progression of carotid intima–media thickness in female patients with active rheumatoid ar…
2009
The objective of the study is to evaluate the effect of TNF inhibition on carotid thickness over a 2-year period. 144 women with RA diagnosed according to ACR criteria, without clinical evidence of cardiac and/or vascular disease were enrolled and compared with 78 matched controls. All patients received methotrexate (15–20 mg weekly) for 3 months. Responders (n = 79) continued to be treated with methotrexate, non-responders (n = 40) moved to methotrexate plus a TNF alpha antagonist. Echosonographic studies of carotids were obtained before and after 2-year follow-up. A significant decrease of ca-IMT was observed in anti-TNF-treated patients (P < 0.001); on the other hand, no significant vari…
Microproteinuria as an index of initial renal lesion in patients with rheumatoid arthritis.
1990
Our investigation included 20 patients with rheumatoid arthritis and a negative routine (albustix) proteinuria test, and 20 healthy controls. The albustix test was compared with a method based on multifractional Cellogel RS electrophoresis of urinary proteins. The albustix test was found to be not reliable in patients with RA. Microproteinuria was in fact detected by the electrophoresis method in 12 out of 20 RA patients. Eleven patients showed glomerular type proteinuria (which was "selective" in 5 patients and "non-selective" in 6 patients), and 1 patient showed mixed type proteinuria. Electrophoresis failed to show microproteinuria in the controls. The high sensitivity, easy handling and…
An intense physical rehabilitation programme determines pain relief and improves the global quality of life in patients with fibromyalgia.
2019
OBJECTIVES:It is accepted that the optimal management of patients with fibromyalgia (FM) requires a combination of non-pharmacological and pharmacological interventions. Our study aimed to analyse the effects of a supplemented physical program on the quality of life of FM patients.METHODS:We enrolled 60 patients, all female (mean age 49±5.7 years), with primary FM (mean years of disease 33±12 months). Patients who agreed to participate in this study met the proposed 1990 American College of Rheumatology classification criteria and the 2010 American College of Rheumatology preliminary diagnostic criteria and were recruited at Policlinico P. Giaccone, University Hospital of Palermo, Italy. Th…
Adult-onset Still’s disease: evaluation of prognostic tools and validation of the systemic score by analysis of 100 cases from three centers
2016
Background: Adult-onset Still's disease (AOSD) is rare inflammatory disease of unknown etiology that usually affects young adults. The more common clinical manifestations are spiking fevers, arthritis, evanescent rash, elevated liver enzymes, lymphadenopathy, hepatosplenomegaly, and serositis. The multi-visceral involvement of the disease and the different complications, such as macrophage activation syndrome, may strongly decrease the life expectancy of AOSD patients. Methods: This study aimed to identify the positive and negative features correlated with the outcome of patients. A retrospective analysis of AOSD patients prospectively admitted to three rheumatologic centers was performed t…
Downregulation of miRNA17-92 cluster marks Vγ9Vδ2 T cells from patients with rheumatoid arthritis
2018
Abstract Background We aimed to evaluate the phenotype, function, and microRNA (miRNA)17–92 cluster expression in Vγ9Vδ2 T-cell subsets and the correlation with immune response in rheumatoid arthritis (RA) patients. Methods Peripheral blood from 10 early RA untreated patients and 10 healthy donors (HD) was obtained. Polyclonal Vγ9Vδ2 T-cell lines were generated and analysed by flow cytometry. Analysis of miRNA17–92 cluster expression was performed by real-time polymerase chain reaction (RT-PCR), and expression of mRNA target genes was also studied. Results A remarkable change in the distribution of Vγ9Vδ2 T-cell functional subsets was observed in the peripheral blood of RA patients compared…
Interleukin (IL)-9/IL-9R axis drives γδ T cells activation in psoriatic arthritis patients
2016
Summary Cytokines such as tumour necrosis factor (TNF)-α, interleukin (IL)-12, interferon (IFN)-γ, IL-23 and, more recently, IL-9, have been implicated in the initiation/maintenance of inflammation in psoriasis and psoriatic arthritis (PsA). In the present study we aimed to characterize the role of γδ T cells in peripheral blood and synovial fluid of PsA patients and to investigate their response to in-vitro stimulation with antigen or cytokines (IL-9 and IL-23). γδ T cells isolated from peripheral blood mononuclear cells and synovial fluid were analysed by flow cytometry to evaluate the phenotype and cytokine production. IL-23R and IL-9R gene expression were also evaluated by reverse trans…
Pathological implications of Th1/Th2 cytokine genetic variants in Behçet's disease: Data from a pilot study in a Sicilian population
2013
Cytokines act as pleiotropic polypeptides able to regulate inflammatory/immune responses and to provide important signals in physiological and pathological processes. Several cytokines (Th1, Th2, and Th17) seem to be involved in the pathophysiology of Behçet's disease, a chronic immune-mediated disease characterized by oral and genital lesions and ocular inflammation. Its individual susceptibility seems to be modulated by genetic variants in genes codifying these cytokines. Th1 and Th17 seem to be involved in the disease's active phases, and Th2 seems to affect the development or severity of the disease; however, contrasting data are reported. In this study, some genetic variants of the Th1…
Type 3 innate lymphoid cells producing IL-17 and IL-22 are expanded in the gut, in the peripheral blood, synovial fluid and bone marrow of patients w…
2015
Background The aim of the study was to better characterise the immunological origin and the behaviour of interleukin (IL)-23-responsive innate lymphoid cells (ILCs) in the gut, synovial fluid (SF) and bone marrow (BM) of patients with ankylosing spondylitis (AS).Methods ILC1, ILC2 and ILC3 cells were determined and characterised by confocal microscopy and flow cytometry in ileal and BM biopsies, in peripheral blood (PB) and SF mononuclear cells obtained from patients with AS and controls. Mucosal vascular addressin cell adhesion molecule 1 (MADCAM-1), IL-7, IL-15 and aggregates of lymphoid tissue inducer cells (LTi) were evaluated by immunohistochemistry. The in vitro ability of epithelial …
Increased expression of interleukin-32 in the inflamed ileum of ankylosing spondylitis patients
2012
Objective. To study the mRNA expression and protein tissue distribution of IL-32 in ileal biopsy specimens from patients with AS. Methods. Quantitative gene expression analysis, by real-time PCR, of IL-32, IL-1b, IL-10, TNF-a and IFN-g was performed on ileal biopsies of 15 AS and 15 Crohn’s disease (CD) patients and 10 healthy subjects (HSs). IL-32 tissue distribution was evaluated by immunohistochemistry. The effect of IL-32 on the production of IL-10 by intestinal epithelial cell lines was also evaluated. Results. In the ileal specimens of patients with AS and intestinal chronic inflammation, significant up-regulation of IL-32 at both the mRNA and protein levels was found as compared with…
IL-34 is overexpressed in the inflamed salivary glands of patients with Sjogren's syndrome and is associated with the local expansion of pro-inflamma…
2013
Objectives To investigate the expression of IL-34 in labial salivary glands (LSGs) of patients with primary SS (p-SS) and its role in inducing a pro-inflammatory monocyte phenotype. Methods LSG biopsies were obtained from 20 patients with p-SS and 10 patients with non-Sjogren's sicca syndrome (n-SS). The expression of IL-34, IL-1β, TNF-α, IL-17 and IL-23 was assessed by real-time PCR. IL-34 expression was also investigated in LSGs by immunohistochemistry. The frequencies of subpopulations of CD14(+) monocytes were evaluated by flow cytometry among isolated mononuclear cells from peripheral blood and salivary glands from both patients and controls. The role of recombinant IL-34 on isolated p…
