Objectives: We aimed to evaluate ixekizumab (IXE) effectiveness, drug survival and clinical response predictors in moderate-severe psoriatic arthritis (PsA) patients in different clinical scenarios., Methods: This was a multicentre real-life observational study based on Gruppo Italiano Studio Early Arthritis (GISEA) registry of IXE treatment in PsA patients (January 2019-June 2023). Data were collected at baseline and every six months., Results: 223 PsA outpatients were included. Statistically significant improvement was observed after 6 (T6), 12 (T12) and 24 (T24) months of therapy for tender and swollen joint count (TJC and SJC), Visual Analogue Scale (VAS)-pain and Disease Activity in PSoriatic Arthritis (DAPSA) score. DAPSA remission was reached at T12 in 22% and at T24 in 18.5% of patients. At baseline, higher fibromyalgia and combination therapy with conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) in females with respect to males and higher Psoriasis Area Severity Index (PASI) in males than in females were observed. Therapeutic effectiveness showed in males higher DAPSA and VAS-pain reduction, higher percentage of males in DAPSA remission/low disease activity (LDA) at T6, and higher ∆PASI at T6 and T12 than in female patients. At multivariate analysis, male sex was predictive for treatment response at T6 [p=0.02, odds ratio (OR) 2.49 (95% confidence interval 1.11-5.54)], while it lost significance at T12., Conclusions: IXE effectiveness was highlighted after 6 months at both joint and skin levels and lasted up to 24 months in different clinical scenarios, making IXE effective in the complexity of managing PsA in a real-life setting.

Systemic sclerosis (SSc) is characterised by a heterogeneous clinical expression probably reflecting the different genetic background of each patient. Progress has been made in the definition of the principal pathogenetic events of the disease that can be summarised in endothelial damage and dysfunction, inflammation with activation of immune system and fibrosis. The aetiology of the disease still remains to be clarified and probably the first events are attributable to the repeated action of environmental stimuli in genetically predisposed subjects.The aim of the present manuscript is to review the most recent and relevant data regarding the association of SSc with environmental factors.

Systemic sclerosis (SSc) is a rare and chronic connective tissue disease of unknown aetiology and characterised by three main pathogenetic events represented by endothelial damage, inflammation with activation of the immune system leading to production of specific autoantibodies and finally fibrosis. SSc is a heterogeneous disease and the classification in two subsets, the limited cutaneous (lcSSc) subset and the diffuse cutaneous one (dcSSc), is not capable of capturing the broad and different phenotypic expression of the disease. In the last years progress has been made in the knowledge of SSc pathogenesis, in its early diagnosis and new therapeutic strategies have been proposed, however, the management of SSc still represents a challenge for the clinician. For this reason, every year several studies investigate new insights of disease pathogenesis, internal organ involvement and therapeutic approaches. The purpose of this review is to provide an overview of the literature published in 2023.

Objectives: To summarise the available evidence and assess the effectiveness of medium and long-term physiotherapy treatment in adults with fibromyalgia (FM)., Methods: This systematic review was registered in PROSPERO: CRD42023388356. The databases searched were MEDLINE, PEDro, Scopus, Cinhal, LatinIndex, and Cochrane, using the following keywords: "fibromyalgia", "physiotherapy", "treatment", "therapeutic exercise", "TENS", "laser therapy" and "manual therapy." The included articles analysed treatments with active or passive physiotherapy approaches in patients with FM. The variables included structural characteristics, such as: author, publication year, research question, and main outcome variables. The data on the findings of the articles comprised the following aspects: number of participants, intervention, follow-up, results, and principal conclusions., Results: Thirty-three articles were analysed, with an overall PRISMA score of 18.63±3.36. The active treatment methods analysed were: movement and body awareness therapies (stretching, tai chi, yoga and Pilates); hydrotherapy; physical or aerobic exercise; and multidisciplinary therapy. The passive therapies analysed were: manual therapy; repetitive transcranial magnetic stimulation (rTMS); and other therapies (hyperbaric oxygen therapy, vibration therapy, virtual reality, transcutaneous electric nervous stimulation (TENS), pain neuroscience education, and acupuncture). Evidence was found on the positive effect of physiotherapy treatment on the signs and symptoms of fibromyalgia, such as pain, impairment of physical capacity and worse quality of life., Conclusions: The effectiveness of the active and passive therapies analysed in the management of the symptoms and signs of the disease was positive in most of the studies. However, more specific descriptions of the treatment protocol, frequency, intensity and treatment dose are required to reach a consensus, as well as primary studies for a more extended follow-up period to better evaluate long-term effects.

Objectives: We aimed to investigate the effectiveness of tumour necrosis factor inhibitors (TNFi), anti-interleukin-17 or interleukin-12/23 monoclonal antibodies (anti-IL) on comorbidities in a cohort of patients with spondyloarthritis (SpA), using an average treatment effect (ATE) analysis., Methods: SpA patients from the multicentre Italian GISEA Registry were divided into groups according to pharmacological exposure: no treatment (G0), TNFi (G1) and non-responders to TNFi switched to anti-IL (G2). In each group, we recorded the prevalence and incidence of infectious, cardiopulmonary, endocrinological, gastrointestinal, oncologic, renal and neurologic comorbidities. Each comorbidity was then fitted for ATE and baseline features were evaluated for importance., Results: The main findings of this study comprising 4458 SpA patients relate to cancer, other gastrointestinal diseases (OGID) and fibromyalgia. ATE showed no increased risk of solid cancer in G1 (0.42 95% CI 0.20-0.85) and G2 (0.26 95% CI 0.08-0.71) vs. G0, with significantly higher incidence in G0 (14.07/1000 patient-years, p=0.0001). Conversely, a significantly higher risk of OGID and fibromyalgia was found in G1 (1.56 95% CI 1.06-2.33; 1.69 95% CI 1.05-2.68, respectively) and G2 (1.91 95% CI 1.05-3.24; 2.13 95% CI 1.14-3.41, respectively) vs. G0. No treatment risk reduction was observed in haematological malignancies, cardiovascular events and endocrinological comorbidities., Conclusions: Overall, our study confirms the safety of TNFi and anti-IL in SpA patients, albeit with some caveats pertaining to solid cancers, OGID and fibromyalgia. Furthermore, taking into consideration causality with observational data may yield more reliable and relevant clinical information.

Objectives: To present the results of a Delphi consensus survey among Italian rheumatologists on adherence to therapy in people with rheumatic and musculoskeletal diseases (RMDs) in Italy and the role of digital health., Methods: A taskforce of 12 rheumatologists comprehensively discussed the applicability of the 2020 EULAR Points to Consider (PtCs) for Italian rheumatology practice and formulated 44 new country-specific statements. Through an on-line survey, the panellists voted on their level of agreement with the statements using a 10-point Likert scale (0: no agreement; 10: total agreement). A combination of two distinct criteria, a mean agreement level ≥8 and a percentage of at least 75% of responses with a value ≥8, was deemed acceptable., Results: The consensus threshold was reached for 43 of the 44 country-specific statements. The following were acknowledged among the barriers to applicability of the recommendations: visit time too short; lack of resources; lack of a clear operational flow-chart; lack of communication skills and poor knowledge of techniques to improve patient adherence by healthcare professionals (HCPs)., Conclusions: This consensus initiative helps contribute to more widespread implementation of EULAR PtCs in Italian rheumatology practice. Optimisation of visit time, greater availability of resources, specific training, use of standardised and validated protocols, and active involvement of patients represent the main goals. Digital health can provide valuable support for the application of PtCs and, more generally, in improving adherence. A collaborative effort between HCPs, patients and their associations, scientific societies, and policymakers is strongly advocated to overcome some of the barriers.

Systemic sclerosis is a rare and chronic connective tissue disease resulting from an intricate pathogenesis and is expressed in very heterogeneous clinical manifestations. Every year many studies try to unravel and shed new insight into the pathogenesis, organ involvement and treatment of this complex and severe disease. We herein provide an overview of the most relevant studies published in the literature in 2022.

Objectives: To determine the cut-off values of Patient Acceptable Symptom State (PASS) for the revised Fibromyalgia Impact Questionnaire (FIQR), the modified Fibromyalgia Assessment Scale (FASmod), and the Polysymptomatic Distress scale (PSD) and to determine the predictors of PASS in patients with fibromyalgia (FM)., Methods: FM patients belonging to the Italian Fibromyalgia Registry (IFR) completed the FIQR, the FASmod and the PSD. The PASS was assessed using a dichotomous answer. The cut-off values were obtained through the receiver operating characteristic curve (ROC) analyses. A multivariate logistic regression analysis was performed to determine predictors of achieving the PASS., Results: 5545 women (93.7%) and 369 males (6.3%) were included in the study. The 27.8% of patients reported an acceptable symptom state. Patients in PASS differed in all patient-reported outcome measures (p <0.001). The FIQR PASS threshold was ≤58 (area under the ROC curve [AUC] = 0.819). The FASmod PASS threshold was ≤23 (AUC = 0.805) and the PSD PASS threshold was ≤16 (AUC = 0.773). In the pairwise AUC comparison, the discriminatory power of the FIQR PASS outperforms both FASmod PASS (p = 0.0124) and PSD PASS (p <0.0001). Multivariate logistic analysis showed that FIQR items related to memory and pain were the only predictors of PASS., Conclusions: The FIQR, FASmod, and PSD PASS cut-off points for FM patients have never been determined before. This study provides additional information to facilitate interpretation of the severity assessment scales in daily practice and clinical research related to FM patients.

Objectives: The revised Fibromyalgia Impact Questionnaire (FIQR) is a widely used fibromyalgia severity assessment tool that was introduced in 2009 prior to the publication of the American College of Rheumatology (ACR) preliminary fibromyalgia criteria in 2010 and its revision in 2016. In 2020, the modified Fibromyalgia Assessment Scale (FASmod) was published. The Polysymptomatic Distress scale (PSD) of the fibromyalgia criteria and FASmod include assessments of pain location severity and can be used for diagnosis as well as in non-fibromyalgia patients. The aim of this study is to provide equations for the conversion of the FIQR scores to PSD and FASmod as an aid to understanding and sharing fibromyalgia severity information., Methods: 3089 patients with fibromyalgia, diagnosed according to the ACR 2010/2011 criteria and belonging to the Italian Fibromyalgia Registry completed FIQR, FASmod and PSD questionnaires. Pearson's correlation coefficient was used to test the correlations between indices. The least square regression approach was used to produce predictive equations for each scale based on the remaining scales., Results: FIQR was correlated with PSD (r=0.714) and FASmod (r=0.801); PSD and FASmod showed the highest correlation (r=0.897), expected since they assess the same constructs. Predictive equations showing a linear model were effective in producing mean cohort values, but individual predictions deviated substantially, precluding prediction in the individual patient., Conclusions: Conversion equations that allow for interconversion of multiple scales fibromyalgia severity assessment scales are produced. These can be useful in obtaining mean values for cohorts but are not accurate enough for use in individual patients.

Objectives: In refractory inflammatory joint diseases (IJDs) biological disease-modifying anti-rheumatic drugs (bDMARDs) may achieve remission. EULAR recommends bDMARD tapering when remission persists. However, guidelines on tapering modalities and criteria for patient selection are lacking. We aimed to evaluate remission persistency after lengthening the time between injections of golimumab in patients affected by IJD and to identify any patient or disease characteristics associated to flare after lengthening., Methods: Patients affected by rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS) and juvenile idiopathic arthritis (JIA) treated with golimumab were enrolled in a retrospective observational study. Demographic data, ESR, cRP, DAS28/ BASDAI, were collected at baseline and during the follow-up (T1- defined as a medical check-up after 1 year of treatment or, for patients with longerg exposure, the first medical check-up in 2016, when at our unit we began to experience drug tapering- and T2- 12 months after the lengthening was started). In 22/80 patients in remission at T1, injection time was lengthened., Results: Eighty patients were enrolled, 34 AS, 33 PsA, 9RA and 4 JIA. At baseline, all had an active disease. At T1, 60/80 patients reached remission and 22/60 patients started tapering. At T2, 20/22 pts (91%) were in remission. At T1 BASDAI was higher (2.2, SD 0.28 vs. 0.58, SD 0.47; p<0.001) in patients who lost remission at T2.Patients who flared recovered remission once taken back to a 28-day interval. 4/38 patients maintained at the standard dose flared up and switched/swapped bDMARD. The difference in retention rate toward patients on reduced dose was not significant., Conclusions: Results show that golimumab lengthening is safe and successfully maintains remission. In patients who experienced a flare after lengthening, the standard regimen promptly restored remission.

Systemic sclerosis (SSc) is an autoimmune disease characterised by microvasculopathy, immune dysregulation, and skin and visceral organ fibrosis. Every year novel insights into the pathogenesis, organ involvement and treatment of this severe disease are published in the scientific community.In this review we report an overview of some of the most relevant contributions published in 2021.

Objectives: Fibromyalgia (FM) is a chronic musculoskeletal pain syndrome of unknown aetiopathogenesis. Its development and maintenance are related to the interplay of biological, psychological, and contextual factors. Among the contextual factors, sociodemographic aspects are poorly elucidated. This study aimed to evaluate the relationships between sociodemographic/clinical factors and symptom severity measures using a web-based registry of patients with FM., Methods: Adult patients with an ACR 2010/2011 diagnosis of FM underwent a clinical evaluation and were asked to complete questionnaires covering their sociodemographic data (gender, age, marital status, educational level), and disease-specific measures (the revised Fibromyalgia Impact Questionnaire (FIQR), and the Polysymptomatic Distress Scale (PDS))., Results: Data relating to 3,221 patients (3001 women and 220 men) was collected. The ANOVA showed significant difference in mean FIQR scores when the five marital conditions (cohabiter, married, separated/divorced, single, widowed) were compared (F 3.321, p<0.01). While males and females were found to have comparable FIQR scores, the interaction between gender and marital status indicated that separated/divorced males have higher FIQR scores (F 5.684, p=0.001). The multiple regression analysis demonstrated that patients who reported lower educational level experienced more severe FM symptoms, as scored with FIQR (p<0.0001)., Conclusions: Our results indicated that being male and separated/divorced is associated to higher severity of FM symptoms, as rated with FIQR. Furthermore, a relationship between educational level and FIQR scores has been detected. This study supports the importance of collecting simple SES measures to identify environmental risk factors for FM severity.

Objectives: The role of age in influencing the severity of fibromyalgia (FM) is still controversial. The aim of this study is to define the contribution of age in the severity of FM from data from a large national database., Methods: This cross-sectional study included adult patients with FM diagnosed according to the 2010/2011 American College of Rheumatology criteria. Disease severity was assessed with the revised Fibromyalgia Impact Questionnaire (FIQR) and the modified Fibromyalgia Assessment Status (FAS 2019mod). Patients were grouped into five age categories (between 18-40 years, between 41-50 years, between 51-60 years, between 61-70 years, and ≥71 years). Differences in disease severity between groups were assessed by one-way analysis of variance (ANOVA)., Results: The study included 2889 patients (199 males and 2690 females), mean age of 52.58 (±11.82) years, with a mean FIQR score of 59.22 (±22.98) and a mean FAS 2019mod of 25.50 (±8.66). Comparing the mean values of the various indices between age categories, there were no statistically significant differences between the groups for FIQR total score and FAS 2019mod. However, the 60-70 years category showed the lowest scores for both scales. The main difference emerged for the FIQR physical function subscale, where the ≥71 years category showed significantly higher scores (p<0.05) compared the 18-40 years category., Conclusions: The severity of FM has a significant level of stationarity according to age categories. Patients between 60-70 years have a lower disease burden. Physical function is the health domain with the most significant difference between the groups.

Systemic sclerosis is a rare and chronic connective tissue disease with a multifaceted pathogenesis characterised by heterogeneous multi-organ clinical manifestations. Every year, many studies contribute to enrich the knowledge on the pathogenesis, organ involvement and treatment of this complex and severe disease. We herein provide an overview on the most relevant contributions published in the literature in 2020.

Objectives: Systemic sclerosis (SSc) is a severe multiple-organ disease characterised by unpredictable clinical course, inadequate response to treatment, and poor prognosis. National SSc registries may provide large and representative patients cohorts required for descriptive and prognostic studies. Therefore, the Italian Society for Rheumatology promoted the registry SPRING (Systemic sclerosis Progression INvestiGation)., Methods: The SPRING is a multi-centre rheumatological cohort study encompassing the wide scleroderma spectrum, namely the primary Raynaud's phenomenon (pRP), suspected secondary RP, Very Early Diagnosis of Systemic Sclerosis (VEDOSS), and definite SSc. Here we describe the demographic and clinical characteristics of a population of 2,028 Italian patients at the initial phase of enrolment, mainly focusing on the cohort of 1,538 patients with definite SSc., Results: Definite SSc showed a significantly higher prevalence of digital ulcers, capillaroscopic 'late' pattern, oesophageal and cardio-pulmonary involvement compared to VEDOSS, as expected on the basis of the followed classification criteria. The in-depth analysis of definite SSc revealed that male gender, diffuse cutaneous subset, and anti-Scl70 seropositivity were significantly associated with increased prevalence of the most harmful disease manifestations. Similarly, patients with very short RP duration (≤1 year) at SSc diagnosis showed a statistically increased prevalence of unfavourable clinico-serological features., Conclusions: Nationwide registries with suitable subsetting of patients and follow-up studies since the prodromal phase of the disease may give us valuable insights into the SSc natural history and main prognostic factors.

Systemic sclerosis (SSc) is a connective tissue disease characterised by diffuse microangiopathy and immune dysregulation which ultimately results in widespread fibrosis of the skin and internal organs. This complex autoimmune disease is characterised by heterogeneous clinical manifestations and variable disease course in which the severity of pathology dictates the disease prognosis and course. Every year novel insights into the pathogenesis, organ involvement and treatment of this severe disease are published. Herewith, we provide an overview of the most significant literature contributions published last year, with the aim of helping the clinician in the understanding and management of SSc patients.

Systemic sclerosis (SSc) is a complex disorder characterised by the involvement of small arteries, microvessels and connective tissue, with deposition of fibrotic tissue and microvascular obliteration in the skin and internal organs. Due to the multifaceted nature of the disease, several articles are published in the medical literature every year, aimed at exploring different aspects of the pathogenesis, internal organ involvement and clinical aspects, and possible therapeutic approaches. In this article we have reviewed the literature on SSc of the past year, with the aim of identifying novel approaches that may help the treating physician in the clinical management of patients.

Systemic sclerosis (SSc) is a connective tissue disorder characterised by immune dysregulation, endothelial cell dysfunction followed by defective vascular repair and neovascularization and progressive tissue fibrosis of the skin and internal organs, whose pathophysiology remains to be fully elucidated. Perturbed neuroendothelial control mechanisms comprising either endothelial cell or peripheral nerve fiber impairment are supposed to play an important role in the onset of Raynaud's phenomenon and development of microvascular abnormalities which are the earliest events and key features of SSc. Such pathogenic neuroendothelial mechanisms may trigger both the early endothelial cell damage and the subsequent loss of peripheral microvascular integrity characterised by the lack of compensatory angiogenesis. Of note, the vascular and nervous systems have several anatomical similarities that extend to molecular level, and the molecular mechanisms of nerve regulation are shared by the vascular system. In this context, increasing evidence demonstrated that endothelial cells express receptors for axon guidance molecules, including Ephrin family receptor tyrosine kinases, Neuropilins, Plexins, Robos, and UNC5B that are able to respond to their soluble neuroendothelial trophic ligands, such as Semaphorins and Slits, to guide the sprouting of endothelial tip cells. Here, we first provide a historical view of neuroendothelial control mechanism alterations in the pathogenesis of SSc, and then discuss the emerging role of a class of molecules sharing neurogenic and angiogenic properties, such as members of Semaphorin/Plexin/Neuropilin and Slit/Roundabout families, in SSc-related peripheral microvasculopathy.

Systemic sclerosis is a rare acquired systemic disease characterised by a complex pathogenesis and multi organ involvement. Every year the scientific world contributes to enrich the knowledge on the pathogenesis, clinical manifestations, diagnosis and treatment of this complex and severe disease. Herewith, we provide an overview of the most significant literature contributions published over the last year.

Objectives: The aim of our study was to evaluate the effect of animal-assisted intervention (AAI), a complementary support to traditional therapies focused on the interaction between animals and human beings, in improving psychological trait, anxiety and pain in a cohort of systemic sclerosis (SSc) patients., Methods: 42 SSc patients, undergoing iloprost intravenous infusion, were divided in three groups: 1) 14 patients submitted to 20 AAI sessions; 2) 14 patients engaged in alternative social activity (control group 1 - C1); and 3) 14 patients without any alternative activity (control group 2 - C2). All patients underwent Visual Analog Scale (VAS), the State-anxiety (STAI-S) and emotional faces at the beginning (s0) and at the end (s1) of each single session, while General Anxiety State-Trait Anxiety Inventory (STAI-T), Beck Depression Inventory (BDI), Social Interaction Anxiety Scale (SIAS), Eysenck Personality Questionnaire-Revised (EPQ-R), the Social Phobia Scale (SPS), the Toronto Alexythymia Scale (TAS-20), the Thought Control Questionnaire (TCQ) were administered at baseline (t0) and at the end of the project (t1)., Results: AAI group showed a significant decrease of the anxiety state level in respect to the two control groups (p<0.001). VAS scale resulted lower both in AAI (p < 0.001) and C1 group (p<0.01). Moreover, STAI-T and TAS scores were significantly reduced in AAI group (p<0.001). TCQ scale showed that patients treated with AAI, compared to control group C2, had greater capacity to avoid unpleasant and unwanted thoughts (p<0.05). In AAI group, the EPQ-R test revealed an enhancement of extroversion trait compared to both control groups (p<0.05)., Conclusions: Our data show that AAI significantly reduces pain perception, anxiety, neuroticism and ameliorates patients' social interaction, therefore it may be a useful to allow a better compliance to traditional therapies.

Objectives: Raynaud's phenomenon and chronic/recurrent digital ulcers (DU) are main features of systemic sclerosis (SSc). Their treatment includes both systemic (i.e., iloprost) and local therapies. We report the therapeutic effects of iloprost in a cohort of SSc patients during a long-lasting follow-up period., Methods: Fifty consecutive SSc patients (M/F 7/43, age at SSc diagnosis 43.5±12.7SD years) received iloprost infusions for 10±4.2SD years. Iloprost schedule consisted in monthly infusion at 0.8-1 ng/kg body weight/min (average cumulative dose 25 μg), according to patients' tolerance. For recalcitrant cases, continuous infusion of iloprost (3 days, average 0.2 mg) was administered., Results: 31/50 (62%) patients showed DU at the beginning of iloprost therapy: among them, 22 (71%) resolved during the follow-up, while the other 9 presented recurrent or chronic DU, despite the treatment. With regards the 19/50 patients without DU at baseline, only one developed skin lesions at the end of 10-year follow-up, when severe pulmonary hypertension developed, which lead to exitus. Considering the 31 patients with DU at baseline, a diffuse skin subset was present in 3/22 patients with healed DU, and in 5/9 who did not (13.6% vs. 55.5%; p=0.027)., Conclusions: Iloprost is a long-term effective treatment to achieve healing and prevention in SSc-related DU. Besides the possible problems concerning patients' tolerability or clinical management, iloprost therapy may be considered of great help in the therapeutic strategy of SSc-related ischaemic manifestations.

Spondyloarthritis represents a heterogeneous group of articular inflammatory diseases that share common genetic, clinical and radiological features. Recently, novel insights into the epidemiology, pathogenesis and treatment of these diseases have been provided. Herewith, we present an overview ofthe most significant literature contributions published over the past year.

Objectives: Interstitial lung disease (ILD) is a key prognostic factor in connective tissue disorders (CTDs). The aim of our study was to assess the changes in pulmonary functional tests (PFTs) in various CTDs, including anti-synthetase syndrome (SYN), systemic sclerosis (SSc) and mixed connective tissue disorder (MCTD), following the use of rituximab therapy., Methods: A multicentre retrospective analysis of patients with ILD secondary to SYN (n=15), MCTD (n=6) and SSc (n=23). PFTs were performed at baseline and at 1 and 2 years of follow-up. The primary outcome was the change in forced vital capacity (FVC) at 1 year., Results: In the SYN population, median FVC changed from 53.0% (42.0-90.0) at baseline to 51.4% (45.6-85.0) at 1 year and 63.0 (50-88) (p=0.6) at 2 years (p=0.14). In SSc, FVC changed from 81.0% (66.0-104.0) at baseline to 89.0% (65.0-113.0) at 1 year (p=0.1) and 74.5 (50-91) at 2 years (p=0.07). In the MCTD population, FVC changed from 64.5% (63.0-68.0) at baseline to 63.0% (59.0-71.0) at 1 year (p=0.6) and 61 (59-71) after 2 years (p=0.8). DLCO showed a trend for improvement in the SYN population (p=0.06 at 1 year and 0.2 at years) while changes remain non-significant in the SSc and MCTD patients. In SYN patients, the percentage of responders at 1 year for FVC (33.3%) was greater than in SSc (9.5%) (p=0.07) and MCTD (17%) (p=0.45). RTX showed a satisfactory safety profile., Conclusions: A trend of improvement of PFTs was observed in SYN patients although not reaching significance, while SSc and MCTD patients were stabilised.

Objectives: In systemic sclerosis (SSc), clinical evidence has shown that Bosentan may foster the regeneration of the peripheral microcirculatory network. The aim of this study was to verify in vitro the influence of Bosentan on the angiogenic performance of dermal microvascular endothelial cells (MVECs) and its possible capacity to counteract the antiangiogenic effects of SSc sera., Methods: Healthy dermal MVECs were challenged with Bosentan at different concentrations (0.1 μM, 1 μM, 10 μM) or with sera from patients with diffuse cutaneous SSc (n=8) and healthy subjects (n=8), alone or in combination with Bosentan (10 μM). Cell viability and chemoinvasion were determined by WST-1 and Boyden chamber assays, respectively. Angiogenesis was evaluated by capillary morphogenesis on Matrigel., Results: Challenge of dermal MVECs with SSc sera induced a significant reduction in angiogenesis (p<0.005 vs. basal condition; p<0.001 vs. healthy sera). The addition of Bosentan could significantly restore angiogenesis in the presence of SSc sera (p<0.01 vs. SSc sera alone). Healthy sera promoted cell viability which was, instead, significantly reduced with SSc sera (p<0.005 vs. healthy sera). The addition of Bosentan to MVECs challenged with SSc sera significantly increased cell viability (p<0.005 vs. SSc sera alone), reaching levels similar to MVECs treated with healthy sera. Co-incubation of MVECs with Bosentan and SSc sera significantly increased chemoinvasion (p<0.005 vs. SSc sera alone) which was inhibited by SSc sera (<0.001 vs. healthy sera)., Conclusions: Bosentan effectively counteracts the antiangiogenic effects of SSc sera on dermal MVECs and fosters the restoration of a proangiogenic environment.

Herewith we provide a critical digest of the recent literature on systemic sclerosis. The most relevant studies published over the last two years have been reviewed, with particular focus on the diagnosis, pathogenesis and treatment of the disease.

Objectives: Chemokines favour leukocyte homing and participate actively in inflammation and accumulation of extracellular matrix. The aim of our work is to assess in patients with systemic sclerosis (SSc) the serum levels of CC chemokines: CCL2 monocyte chemotactic protein-1 (MCP-1/CCL2), CCL5 'regulated upon activation, normal T expressed and secreted' (RANTES/CCL5) and CCL3 'macrophage inflammatory protein 1 α' (MIP1α/CCL3), their associations with clinical characteristics and modulation by infusions of the prostaglandin E1 (PGE1) analogue, alprostadil alpha-cyclodextrin., Methods: Serum levels of MCP1/CCL2, RANTES/CCL5 and MIP1α/CCL3 were studied by ELISA in 40 patients with SSc (34 lSSc, 6 dSSc) before and after 3 consecutive daily PGE1 infusions (60 μg) and compared to 30 healthy controls. We recorded clinical (age, duration of disease, ulcers, teleangectasias, calcinosis, skin score [mRSS], capillaroscopy pattern, heart and lung involvement) and immunological characteristics (ANA/ACA/Scl70) of patients., Results: MCP1/CCL2, RANTES/CCL5 and MIP1α/CCL3 levels were significantly higher in SSc patients than in controls and significantly decreased after PGE1 treatment. MCP-1 levels, higher in dSSc and Scl 70 positive patients, correlated with mRSS., Conclusions: The high levels of circulating chemokines might support a role of MCP1/CCL2, RANTES/CCL5 and MIP1α/CCL3 in SSc pathogenesis and the correlation of MCP-1 with the extent of skin fibrosis might imply its involvement in the development of fibrosis in SSc. PGE1 down-regulates serum MCP1/CCL2 and RANTES/CCL5 levels, suggesting its possible additional effect on inflammation and cell trafficking in SSc.

Given the availability of novel biologic agents for the treatment of rheumatoid arthritis (RA), various national scientific societies have developed specific recommendations in order to assist rheumatologists in prescribing these drugs. The Italian Society for Rheumatology (Società Italiana di Reumatologia, SIR) decided to update its recommendations and, to this end, a systematic literature review was carried out and the evidence derived from it was discussed and summarised as expert opinions. Levels of evidence, strength of recommendations and levels of agreement were reported. The recommendations reported are intended to help prescribing rheumatologists to optimise the use of biologic agents in patients with RA seen in everyday practice; they are not to be considered as a regulatory rule.

Systemic sclerosis (SSc) is a complex systemic disease characterised by fibrosis of the skin and internal organs, vasculopathy, and activation of the immune system. The complex pathophysiology of SSc implies the potential involvement of 'culprit' genes, either individually or, more likely, together, in driving the disease process. Most of the studies that have provided evidence for the contribution of various genes/loci in SSc pathogenesis are based on a candidate gene approach, on the basis of a shared autoimmune genetic background with other autoimmune diseases, such as systemic lupus erythematosus. In fact, autoimmune genes seem to play a pivotal role in SSc pathogenesis, while less is known about the genetic involvement in vasculopathy and fibrosis. Recently, the availability of genome-wide association studies, which make it possible to screen single-nucleotide polymorphisms across the entire genome without previous knowledge of candidate regions or genes, has yielded a wealth of new genetic susceptibility loci leading to the identification of new pathogenetic mechanisms of complex genetic disorders. In this article, we aim to provide a comprehensive review of recent studies on the genetics of SSc, including genes associated with autoimmunity, fibrosis, and vascular disease. We also discuss the most relevant data obtained in genetic association studies of large populations that included a replication strategy, or studies for which independent replication was available.

Background: Microparticles (MPs) are increased in diseases characterised by endothelial injury. Kawasaki disease (KD) damages the endothelium provoking life-threatening involvement of coronary arteries., Objectives: To compare KD MPs vs. controls. METHODS. Thirty KD and 20 controls were enrolled. MPs were stained with monoclonal antibodies against platelets, endothelial cells (EC), monocytes, T and B cells, neutrophils, and quantified by FACS., Results: The total number of MPs was significantly increased in KD versus controls (193x105±0.6x105 vs. 94x105±0.9x105 million/ml plasma p=0.01) and vs. KD after IVIG therapy (132x105±0.4x105million/ml plasma p=0.01). EC and T cells were the major source of MPs in KD (72x105±1x105 vs. 3x105±0.9x105million/ml plasma for T cells p=0.005; 76x105±0.7x105 vs. 45x105±0.4x105 million/ml plasma for EC p<0.02) followed by MPs derived from platelets (13x105±0.3x105 vs. 3x105±0.9x105 million/ml plasma p=0.028). Cell-derived MPs B were 17x105±0.4x105 vs. 20x105±0.8x105million/ml plasma in controls (p=0.7). No significant differences were observed in KD MPs derived from monocytes and neutrophils. After IVIG administration, a significant decrease of MPs derived from platelets (3x105±0.2x105 million/ml plasma p=0.03), EC (9x105±0.4x105 million/ml plasma p=0.01), T cells (72x105±1x105 million/ml plasma p=0.02) and B cells (7x105±0.3x105 million/ml plasma p=0.02) was observed., Conclusions: The number of KD MPs is significantly increased and EC and T cells are the major source. MPs may develop from endothelial damage and cell activation. Their role as markers of disease activity or as contributors to endothelial derangement in KD has to be further investigated.
