Dual αvβ3 and αvβ5 blockade attenuates fibrotic and vascular alterations in a murine model of systemic sclerosis.

Systemic sclerosis (SSc) is a connective tissue disorder characterized by fibroblast activation and fibrosis of the skin and internal organs. Alterations in cell-integrin interaction are sufficient to initiate profibrotic processes. SSc fibroblasts express both αvβ3 and αvβ5 integrins and their activation induces myofibroblasts differentiation.

Mastocytosis and systemic sclerosis: a clinical association.

Background: Systemic sclerosis (SSc) is a complex autoimmune disease characterized by vascular alterations and autoimmune activation leading to widespread organ fibrosis. At the early stage of disease when organ involvement and extent of disease are emerging, mast cells may have some role, as implied by both symptoms and histologic evidence.

Case Presentation: A female patient diagnosed with cutaneous mastocytosis experienced the onset of systemic sclerosis after 15 years followed by the switch of mastocytosis to the systemic phenotype.

Clinical, autoimmune, and psychiatric parameters correlate with sleep disturbance in patients with systemic sclerosis and rheumatoid arthritis.

Objectives: Sleep disturbance is an important contributor to poor quality of life in rheumatic disorders. This study aims to test whether clinical, autoimmune and psychological factors are associated with sleep disturbance in systemic sclerosis (SSc) compared to rheumatoid arthritis (RA) patients and controls.

Methods: 101 female subjects (SSc=33, RA=34, healthy controls=34) participated in this observational, cross-sectional, parallel group study.

Patient-reported impact of spondyloarthritis on work disability and working life: the ATLANTIS survey.

Background: The aim was to establish how patients experience the impact of spondyloarthritis (SpA) on work disability and working life.

Methods: The survey was performed in 17/20 regions in Italy (1 January to 31 March 2013). A multiple-choice questionnaire was published on the official website of the sponsor - the National Association of Rheumatic Patients (ANMAR) - and hard-copies were distributed at outpatient clinics for rheumatic patients.

Propylthiouracil modulates aortic vasculopathy in the oxidative stress model of systemic sclerosis.

Background: In systemic sclerosis (SSc) vasculopathy affects small arteries and capillaries, but recent evidences show also macrovascular alterations. Experimental data suggest that propylthiouracil (PTU) abrogates the development of cutaneous and pulmonary fibrosis during SSc. The aim of this study was to evaluate the effect of propylthiouracil on aortic lipid peroxidation, intima-media thickness and myofibroblasts differentiation in experimental SSc.

Toll-like receptor 3 and interleukin 1β expression in CD34+ cells from patients with rheumatoid arthritis: association with inflammation and vascular involvement.

Objectives: Circulating proangiogenic haematopoietic cells (PHCs), including CD34+ cells, play an important role in endothelial homeostasis. Among PHCs, CD34+ cells are the largest cell population, thus, much of the regenerative/reparative potential of PHCs may be attributed to CD34+ cells. Our aim was to determine the association between inflammation and CD34+ cell number, intracellular levels of reactive oxygen species (ROS) and expression of Toll-like receptor 3 (TLR3) and interleukin 1β (IL-1β), arterial stiffness (AS) indices, and carotid intima-media thickness (cIMT) in patients affected by rheumatoid arthritis (RA).

Safety of etanercept and methotrexate in patients with rheumatoid arthritis and hepatitis C virus infection: a multicenter randomized clinical trial.

Objective: To evaluate the safety and efficacy of therapy with etanercept and methotrexate (MTX) in patients with active rheumatoid arthritis (RA) and mild hepatitis C virus (HCV) infection.

Methods: In this prospective open study, 29 patients with active RA were randomly assigned to receive therapy with MTX alone, etanercept alone, or a combination of MTX and etanercept, and monitored up to 54 weeks. The primary endpoint was safety; secondary aims were efficacy as defined by the 44-joint Disease Activity Score (DAS44) and health assessment questionnaire (HAQ).

Pain threshold and intensity in rheumatic patients: correlations with the Hamilton Depression Rating scale.

Individuals suffering from chronic pain are frequently affected by depression, which in turn increases the risk of developing chronic pain over time. This study aims to investigate the relationship between depression and pain intensity and threshold in a group of rheumatic patients compared to healthy subjects. One hundred twenty-four individuals of whom 50 were affected by rheumatoid arthritis (RA), 23 by psoriatic arthritis (PsA), 23 by ankylosing spondylitis (AS), and 28 age-matched controls without chronic pain underwent quantitative sensory testing to assess pressure pain threshold with pressure algometry.

Propylthiouracil prevents cutaneous and pulmonary fibrosis in the reactive oxygen species murine model of systemic sclerosis.

Introduction: Recent advances suggest that the cellular redox state may play a significant role in the progression of fibrosis in systemic sclerosis (SSc). Another, and as yet poorly accounted for, feature of SSc is its overlap with thyroid abnormalities. Previous reports demonstrate that hypothyroidism reduces oxidant stress.

Bone mineral density, bone turnover markers and fractures in patients with systemic sclerosis: a case control study.

Objective: The aim of our study was to elucidate the pathophysiology of systemic sclerosis-related osteoporosis and the prevalence of vertebral fragility fracture in postmenopausal women with systemic sclerosis (SSc).

Methodology: Fifty-four postmenopausal women with scleroderma and 54 postmenopausal controls matched for age, BMI, and smoking habits were studied. BMD was measured by dual energy-x-ray absorptiometry at spine and femur, and by ultrasonography at calcaneus The markers of bone turnover included serum osteocalcin and urinary deoxypyridinoline.

Simvastatin attenuates the development of pulmonary and cutaneous fibrosis in a murine model of systemic sclerosis.

Objective: The antifibrotic effect of simvastatin has been demonstrated in human lung fibroblasts. This study aimed to measure the effects of simvastatin in the development of pulmonary and cutaneous fibrosis in a murine model of SSc and to explore the mechanisms of these effects.

Methods: Chronic oxidant stress SSc was induced in BALB/c mice by daily s.

Remission in early, aggressive rheumatoid arthritis: a multicentre prospective observational Italian study ARPA (Artrite Reumatoide Precoce Aggressiva).

Objectives: To provide a survey of disease activity in patients treated with standard care in Italian clinical practice.

Methods: This was an observational prospective cohort study in patients with early, aggressive rheumatoid arthritis (RA; duration ≤2 years but ≥6 weeks; DAS28 >3.2) naïve to anti-tumour necrosis factor (TNF) therapy who were treated with disease-modifying anti-rheumatic drugs (DMARDs) and/or biologics according to standard practice at 15 Italian ARPA (Artrite Reumatoide Precoce Aggressiva) centres.

Role of 2D strain in the early identification of left ventricular dysfunction and in the risk stratification of systemic sclerosis patients.

Background: Systemic sclerosis (SSc) is an autoimmune chronic disease characterized by diffuse fibrosis involving several organs, including heart. Aim of our study was to analyze left ventricular (LV) myocardial deformation, by use of 2D strain, in asymptomatic SSc patients with normal LV ejection fraction.

Methods: We enrolled 29 SSc patients (28 female, 65±4 years) and 30 controls (23 female, 64±2 years).

Polydeoxyribonucleotide reduces cytokine production and the severity of collagen-induced arthritis by stimulation of adenosine A(₂A) receptor.

Objective: Broad antiinflammatory effects following adenosine A(₂A) receptor stimulation have been demonstrated in acute inflammatory diseases, including arthritis. Polydeoxyribonucleotide (PDRN) activates the adenosine A(₂A) receptor. This study was undertaken to investigate the effects of PDRN in collagen-induced arthritis (CIA) in mice.

Bone mineral density, quantitative ultrasound parameters and bone metabolism in postmenopausal women with depression.

Low bone mineral density, which increases the risk of stress fragility fractures, is a frequent, often persistent finding in patients with major depressive disorder (MDD). The clinical association between major depressive disorder and osteopenia is still unclear, although several factors are associated with a loss of bone mass. The aim of our study, therefore, was to evaluate bone mineral density and bone metabolism in patients with MDD.

Early identification of vascular damage in patients with systemic sclerosis.

Vascular involvement in systemic sclerosis (SSc) plays a key role in the pathogenesis of fibrosis. We assessed arterial stiffness using a new echo-tracking technique in patients with SSc asymptomatic for cardiovascular diseases. We enrolled 22 patients (21 female, 63 ± 14 years) and 20 controls (12 female, 62 ± 3 years).
