Safety and efficacy of intra-articular anti-tumor necrosis factor α agents compared to corticosteroids in a treat-to-target strategy in patients with…
2015
The aim of this study was to assess safety and efficacy of ultrasonography (US)-guided intra-articular injections using tumor necrosis factor (TNF) blockers compared to corticosteroids in rheumatoid arthritis (RA) or psoriatic arthritis (PsA) patients, experiencing refractory monoarthritis despite the current systemic therapy. Eighty-two patients were randomized to receive three intra-articular injections monthly of either corticosteroid or TNF blockers. Primary endpoints were the safety and an improvement greater than 20% for visual analogic scales of involved joint pain in patients injected with anti-TNFα. Further clinical, US, and magnetic resonance imaging (MRI) evaluations were consid…
Interleukin-9 and T helper type 9 cells in rheumatic diseases
2016
Summary Interleukin (IL)-9 is a 28-30 kDa monomeric glycosylated polypeptide belonging to the IL-7/IL-9 family of proteins that bind to a composite receptor consisting of the private receptor IL-9R and the IL-2 receptor, gamma (IL-2RG), a common gamma subunit shared by the receptors of many different cytokines. The IL-9R is expressed widely and IL-9 impacts a number of effector cells, such as effector T cells, B cells, innate lymphoid cells, mast cells, polymorphonuclear cells, epithelial cells and smooth muscle cells, playing an important role in regulating inflammatory immunity. The critical role of IL-9 in promoting cellular and humoral immune responses makes it an important focus of pot…
A 588-gene microarray analysis of the peripheral blood mononuclear cells of spondyloarthropathy patients
2002
OBJECTIVES: To identify genes which are more highly expressed in the peripheral blood mononuclear cells (PBMC) of patients with spondyloarthropathy (SpA), rheumatoid arthritis (RA) and psoriatic arthritis (PsA), in comparison to normal subjects. METHODS: A 588-gene microarray was used as a screening tool to select a panel of such genes from PBMC of these subjects and of normal subjects. Results were then validated by reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: The following genes were more highly expressed in arthritis patients than in normal subjects: macrophage differentiation marker MNDA (myeloid nuclear differentiation antigen), MRP8 and MRP14 (migratory inhibitor…
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…
T cells involved in psoriasis vulgaris belong to the Th1 subset
1994
Although the pathogenesis of psoriasis vulgaris is still unknown, several characteristics point to an immunologically mediated process. Epidermal psoriatic lesions are characterized by a hyperproliferation of keratinocytes and an infiltration of T lymphocytes and granulocytes. Because the former may be mediated in part by lymphokines secreted by T cells, we have focused our interest on the in vivo and in vitro cytokine secretion patterns of T lymphocytes from psoriatic lesions. In five patients T lymphocytes were obtained from epidermal specimens. The cells were propagated with lectin and irradiated feeder cells and subsequently cloned by limiting dilution. The resulting T-cell clones were …
Differential association of polymorphisms in the TNFalpha region with psoriatic arthritis but not psoriasis.
2002
To investigate the potential association of tumour necrosis factor alpha (TNFalpha) microsatellite and promoter alleles with psoriatic arthritis (PsA).DNA from 89 white patients with PsA, 65 patients with psoriasis, and 99 healthy white controls was investigated for two TNFalpha promoter (-238 and -308) and three microsatellite polymorphisms (TNFa, c, and d). Patients had previously been studied by serology for HLA class I antigens and by sequence-specific polymerase chain reaction for DRB1* alleles. In addition, TNFalpha production of Ficoll separated peripheral blood mononuclear cells (PBMC) into culture supernatants after stimulation with lipopolysaccharide, alphaCD3 antibodies, phytohae…
Psoriatic arthritis onset in psoriatic patients receiving UV phototherapy in Italy
2018
Abstract BACKGROUND: Psoriasis is a chronic, recurrent, and immune-mediated inflammatory disease that affects 2-3% of the world population. A substantial proportion of patients with psoriasis, approximately 40 %, develop a form of inflammatory arthritis known as psoriatic arthritis (PsA), the arthritis follows the development of psoriasis, and it will develop simultaneously or possibly before the appearance of skin lesions. The presence of PsA indicates a need for more active intervention rather than purely topical therapies or UV-based therapies. The aim of this multicenter, retrospective, epidemiological study was to estimate the incidence of PsA in psoriatic patients receiving UV treatme…
Adalimumab for treatment of moderate to severe psoriasis and psoriatic arthritis
2008
Psoriasis and psoriatic arthritis are common diseases associated with considerable morbidity and disability. Their pathophysiology comprises similar processes leading to inflammation of skin, entheses, and joints. Although traditional systemic agents can be effective, their use may be limited by lack of efficacy and concerns regarding adverse effects. The objective of this study was to assess the efficacy and safety of adalimumab, a fully human antitumor necrosis factor (anti-TNF) monoclonal antibody, over 16 weeks. The present authors report their personal experience in 15 patients with severe plaque psoriasis and psoriatic arthritis, refractory to other treatments, in which a decisive reg…
Achilles tendon ultrasonography may detect early features of psoriatic arthropathy in patients with cutaneous psoriasis.
2014
SummaryBackground Psoriatic arthropathy is a progressive and debilitating disease involving reduction of functional activity of the articulations with consequent deterioration of the patient's quality of life. The entheses represent the initial site of articular inflammation and the enthesis of the Achilles tendon is the first to be affected. In some patients with psoriasis, enthesitis may not be diagnosed because it is still asymptomatic. Objectives To evaluate whether ultrasonography allows early diagnosis in a larger population and to identify significant alterations of enthesitis beyond increased thickness of the Achilles tendon. Materials and methods The study was undertaken on 59 pati…
Effects of Strength Training on Neuromuscular Function and Disease Activity in Patients with Recent-onset Inflammatory Arthritis
1994
Thirty-nine consecutive patients with recent-onset rheumatoid or psoriatic arthritis were randomly allotted for six months period either to the experimental progressive dynamic strength training group (EG, 10 women and 11 men; 41 +/- 10 yrs), or to the control group (CG, 10 women and 8 men; 45 +/- 11 yrs) who just maintained their habitual physical activities. All patients received antirheumatic medication throughout the experimental period. During the study period significant improvements took place in the EG in maximal muscle strength of all examined muscle groups (31.5% for the knee extensors, p0.001; 14.8% and 10.7% for the trunk flexors and extensors, p0.01; 27.8% and 20.4% for grip st…
