Gene therapy for chondral and osteochondral regeneration: is the future now?
2017
Gene therapy might represent a promising strategy for chondral and osteochondral defects repair by balancing the management of temporary joint mechanical incompetence with altered metabolic and inflammatory homeostasis. This review analysed preclinical and clinical studies on gene therapy for the repair of articular cartilage defects performed over the last 10 years, focussing on expression vectors (non-viral and viral), type of genes delivered and gene therapy procedures (direct or indirect). Plasmids (non-viral expression vectors) and adenovirus (viral vectors) were the most employed vectors in preclinical studies. Genes delivered encoded mainly for growth factors, followed by transcripti…
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…
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…
Inactivation of the KSRP gene modifies collagen antibody induced arthritis.
2017
Abstract The KH type splicing regulatory protein (KSRP) is a nucleic acid binding protein, which negatively regulates the stability and/or translatability of many mRNA species encoding immune-relevant proteins. As KSRP is expressed in immune cells including T and B cells, neutrophils, macrophages and dendritic cells, we wanted to analyze its importance for the development of autoimmune diseases. We chose collagen antibody-induced arthritis (CAIA) as an appropriate autoimmune disease mouse model in which neutrophils and macrophages constitute the main effector cell populations. We compared arthritis induction in wild type (WT) and KSRP−/− mice and paws were taken for histological sections an…
Research Article <i>CD40</i> rs4810485 <i>T>G</i> polymorphism and susceptibility to ankylosing spondylitis in the Latvian…
2018
Ankylosing spondylitis (AS) is a potentially disabling form of a systemic chronic inflammatory arthritis affecting mainly the axial skeleton, with or without extraspinal manifestations. The genetic basis of AS is partly known. Moreover, many autoimmunityrelated genes have pleiotropic effects. Multiple functional polymorphisms in the genes encoding the tumor necrosis factor (TNF) superfamily of cytokines, their receptors, and signaling proteins, are associated with susceptibility to autoimmune diseases. These arguments prompted us to conduct a study evaluating a possible association of single nucleotide polymorphism (SNP) rs4810485 of the CD40 gene, found previously to be involved in other i…
FRI0349 PSORIATIC ARTHRITIS AND CENTRAL OBESITY: STRONG ASSOCIATION WITH FUNCTIONAL DISABILITY AND A WORSE QUALITY OF LIFE
2020
Background:Psoriatic arthritis (PsA) is a chronic inflammatory arthritis associated with comorbidities like obesity, metabolic syndrome, and cardiovascular disease. Adipose tissue leads to a pro-inflammatory status in obese subjects. For this reason, central obesity may determine a worsening in both disability index or quality of life in PsA patients treated with biologic agents.Objectives:Our study aimed to evaluate the relationship between central obesity and disability index or the impact of the disease on quality of life in a real-world sample of PsA patients.Methods:A cross-sectional study was conducted. Patients with PsA were enrolled at the PsA clinic at the ARNAS Civico in Palermo (…
Expression of host defense scavenger receptors in spondylarthropathy
2001
Objective Reactive arthritis (ReA) is postulated to be caused by a defective host defense against gram-negative bacteria. HLA–B27 could play a role in this process, but does not account for the many HLA–B27 negative patients. The objective of this study was to test the expression of 3 macrophage scavenger receptors (SRs) that are responsible for innate immunity against gram-negative bacteria: SR class A type I (SR-AI), SR-AII, and the macrophage receptor with collagenous structure (MARCO). We postulate that defects in such receptors might also contribute to the host risk factors that increase the predisposition to ReA and perhaps other subtypes of spondylarthropathy (SpA). Methods Periphera…
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…
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…
Muscle strength in healthy people and in patients suffering from recent-onset inflammatory arthritis.
1995
Neuromuscular function was compared among 20 patients with relatively recent onset (symptomatic period 17 +/- 24 months) rheumatoid arthritis (RA) (experimental group; EG), and 20 age- and sex-matched healthy people (control group; CG). The comparison was repeated after a period of 6 months, when 16 patients had carried out progressive strength training. At baseline maximal grip strength and maximal dynamic unilateral strength of the knee extensors in the EG were significantly (P < 0.05) lower in comparison to the CG. The groups did not differ from each other in maximal isometric strength of the trunk flexors and extensors or the knee extensors. The 6-month dynamic strength training in the …
