RESUMEN
OBJECTIVES: Bosentan is a dual endothelin receptor antagonist approved for the treatment of SSc digital ulcers (DU) and pulmonary arterial hypertension (PAH). Systolic pulmonary arterial pressure (sPAP) is a relevant parameter for the follow-up and prognosis of SSc-PAH. The therapeutic magnitude of bosentan in SSc-PAH is not fully understood, thus we aim to establish the degree of sPAP reduction in bosentan treated SSc-PAH patients. METHODS: We performed a systematic literature review in three databases from January 2000 to June 2023, involving sPAP measurement at transthoracic echocardiography of SSc patients before and after starting bosentan. Following the study quality assessment and data extraction, we performed random-effects meta-analysis and Egger's test for publication bias. Stratified analysis was performed for mono-/combination therapy, follow up duration (≤1 year), indication for bosentan therapy (PAH or DU/mixed). RESULTS: In the 11 selected manuscripts, sPAP mean difference before and after bosentan therapy was - 5.63mmHg (CI95% -9.79 to -1.48, p=0.0078). In stratified analysis, sPAP mean was significantly different before and after bosentan therapy only for studies considering < 1 year of follow-up (p=0.0020), monotherapy (p=0.0140) and the strict indication for PAH (p=0.0002). CONCLUSIONS: Bosentan significantly decreases sPAP, a relevant prognostic marker, especially in overt SSc-PAH. However, bosentan did not decrease sPAP when started for DU/mixed indication nor for follow-up>1 year. The burden of publication bias was significant. Therefore, further studies are required to assess bosentan's haemodynamic effect in high-risk patients for SSc-PAH.

OBJECTIVES: We aimed to evaluate the drug retention rate (DRR) of secukinumab, an anti-IL-17A monoclonal antibody, in patients with psoriatic arthritis (PsA) in a real-life cohort, and to assess the impact of comorbidities and patient clinical characteristics on the DRR of secukinumab. METHODS: A retrospective study of prospective followed-up patients was performed to evaluate the DRR of secukinumab on patients with PsA attending the recruiting centres between January 2016 and June 2022. RESULTS: In 207 patients with PsA, a 60-month DRR of secukinumab of 57.0% was estimated (mean time of administration of 21.5±17.1 months). Male gender, age ≥65 years, disease duration ≥5 years and ≥10 years did not influence the DRR of secukinumab. The presence of comorbidities, considering any concomitant disorder, did not affect the DRR of secukinumab. In patients with cardiometabolic multimorbidity, a trend toward a better DRR of secukinumab was recorded. In fact, patients with high blood pressure, dyslipidaemia, and type 2 diabetes showed a trend toward an improved DRR of secukinumab. Furthermore, the presence of obesity did not influence the DRR of secukinumab. Different dosages, previous bDMARDs, and concomitant therapy with csDMARDs did not influence the DRR of secukinumab. CONCLUSIONS: A cumulative 60-month DRR of secukinumab of 57.0% in patients with PsA was retrieved. The presence of cardiometabolic multimorbidity could be associated with an improved DRR of secukinumab, whereas obesity did not affect this feature in our cohort. Previous bDMARDs, concomitant csDMARDs, and different drug dosages could not influence the DRR of secukinumab over time.

OBJECTIVES: Conflicting results about clinical and subclinical atherosclerosis in systemic sclerosis (SSc) and the associated risk factors have been reported. Hence, we aimed to determine the prevalence of clinical and subclinical atherosclerosis in a large number of Italian SSc patients and the associated risk factors. METHODS: This study included 613 SSc patients from 11 Italian tertiary Rheumatologic Units. All patients underwent full history taking, clinical examination, and relevant laboratory and radiological investigations. Doppler ultrasonography (US) of the common carotid and upper and lower limbs was performed to measure carotid and femoral intima-media thickness (cIMT and fIMT), and carotid and peripheral atheroma plaques. Doppler US of the brachial artery was performed to measure flow-mediated dilatation (FMD). RESULTS: Patients were mostly women (91.4%) with a median age of 61 years (range, 20-100); a median disease duration of 14 years (range, 0-77) from the onset of the first non-Raynaud's phenomenon (RP); 9.3% had a history of clinical atherosclerosis (9 stable/unstable angina, 21 myocardial infarctions, 24 heart failure, 3 strokes, 8 transient ischaemic attack, 6 intermittent claudication, 10 atrial thrombo-embolism). In 37.1% of patients, subclinical atherosclerosis was detected, after excluding those with a history of clinical atherosclerosis. The prevalence of clinical and subclinical atherosclerosis was higher than that reported by the European Society of Cardiology and observational studies that enrolled Italian healthy individuals as a control group, respectively. CONCLUSIONS: A higher prevalence of clinical and subclinical atherosclerosis was detected in SSc Italian patients and correlated with traditional and SSc-related risk factors.

Anti-fibroblast antibodies (AFA) have been reported in systemic sclerosis (SSc) and are known to promote fibroblast activation. Aim of this study was to characterize the fine specificity of AFA and to analyze any correlations with clinical parameters associated to fibrosis. To this end, AFA were affinity-purified from a patient with diffuse cutaneous SSc (dcSSc) and interstitial lung disease (ILD). Panning of a phage display peptide library with purified AFA identified the motif

OBJECTIVES: The coronavirus disease 19 (COVID-19) pandemic concerns the field of rheumatology in many ways. Arthritis in conjunction with COVID-19 is increasingly reported. However, clinical data are still limited and there is lack of a detailed characterisation of COVID-19 associated arthritis by musculoskeletal ultrasound (MSUS). This case series reports different forms of COVID-19 associated arthritis supported by MSUS in patients with or without underlying rheumatic and musculoskeletal disease (RMD). METHODS: From March 2020 to July 2021, adult patients (n=10) with arthritis timely related to COVID-19 were assessed in three European centres by clinical and laboratory values and additionally MSUS. RESULTS: In the group without underlying RMD (n=6), two patients presented with polyarticular arthralgia during severe COVID-19, swelling was rarely seen and MSUS demonstrated arthritis only in a few joints affected. The other four patients showed arthritis four to 16 weeks after mild or moderate COVID-19 (without hospitalisation): polyarthritis (n=1), oligoarthritis of the upper and lower limb (n=2), and in one case, late-onset rheumatoid arthritis (LORA) was newly diagnosed. In the group with an underlying RMD (n=4), an increase of disease activity was reported by MSUS during mild and mild-moderate COVID-19. In general, MSUS often presented power Doppler (PD) positive synovitis and tenosynovitis. CONCLUSIONS: In our patients without underlying RMD, arthritides associated with COVID-19 are comparable to the clinical picture of a reactive arthritis (ReA) or other virus-related arthritides (e.g. parvovirus B19). New onset or flares of RMD possibly triggered by COVID-19 are noteworthy.

OBJECTIVES: Due to the prevalence of fibromyalgia in psoriatic arthritis (PsA) patients, any evaluation about PsA-specific patient-reported outcomes (PROs) should take in account the possible bias related to this comorbidity. Patient acceptable symptom state (PASS) is a patient-reported measure evaluating the acceptable and/or satisfactory level of symptoms in rheumatic diseases, which has been proposed as a disease activity index, in patients with PsA. Thus, this study was designed to analyse if the association between PASS and PsA disease activity may be biased by the presence of comorbid fibromyalgia. METHODS: A multi-centre, cross-sectional, observational study enrolling consecutive PsA participants has been conducted from July 2021 to November 2021. The Disease Activity for Psoriatic Arthritis (DAPSA) was collected; the following formulation of PASS question: 'Think about all the ways your PsA has affected you during the last 48 hours. If you were to remain in the next few months as you were during the last 48 hours, would this be acceptable to you?', was submitted to our participants. RESULTS: Multivariable logistic regressions, adjusted for the presence of fibromyalgia, did not show any significant association between PASS and DAPSA low disease activity, DAPSA as nominal variable (remission, low disease activity, moderate disease activity, high disease activity) and DAPSA as continuous variable. CONCLUSIONS: Our data suggest that fibromyalgia influences the patient's perception of the disease and has a negative impact on PASS status independently of disease activity, thus limiting the utility of this Patient reported outcome in real world clinical practice.
RESUMEN
OBJECTIVES: Psychosocial factors are recognised as important determinants of pain experience in patients with inflammatory arthritides. Among them, pain catastrophising, a maladaptive cognitive style, observed in patients with anxiety and depressive disorders, garnered specific attention. Here, we evaluated pain catastrophising (PC) and its related domains (Rumination, Magnification, and Helplessness), in psoriatic arthritis (PsA) and axial spondyloarhtiritis (axSpA) participants, to assess its impact on disease activity. Furthermore, we analysed possible correlations of PC-Scale (PCS) with those psychometric domains which have been already related to catastrophisation in patients with chronic pain. Lastly, we aimed to define the relationship between PCS and the different variables included in the composite indices of disease activity. METHODS: A multi-centre, cross-sectional, observational study has been conducted on 135 PsA (age 56 (47-64) years, males/females 40.74/59.26%; Disease Activity in Psoriasic Arthritis (DAPSA) 13.34 (5.21-22.22)) and 71 axSpA (age 49 (37-58) years, males/females 56.34/43.66%; Bath Ankylosing Spondylitis Arthritis Activity (BASDAI) 4.17 (2.1-6.3)) participants. Multivariable regressions and correlations were performed to evaluate the relationship between pain catastrophising and both disease activity and patient-reported outcomes. RESULTS: The adjusted linear regression model showed a positive association between PCS and DAPSA as well as between PCS and BASDAI; PCS negative impacts on the subjective domains of disease activity scores. CONCLUSIONS: This study suggests the role of PC, independently of inflammation, in disease perception and achievement of remission or low disease activity in chronic arthritides.

OBJECTIVES: To multidimensionally characterize macrophage activation syndrome (MAS) complicating adult-onset Still's disease (AOSD) considering cytokine profile, inflammatory markers and multi-visceral involvement of the disease. To perform a high-dimensional phenotypic analysis of circulating immune cells in AOSD patients with and without MAS. To assess interferon (IFN)-related pathways in AOSD synovial tissues by a bulky RNA sequencing. METHODS: Clinical and biologic data were collected and compared in AOSD patients with and without MAS. Sera biomolecules were analysed by Luminex multiplexing technology. Mass cytometry (CyTOF) was used to characterize circulating immune cells. A bulky RNA sequencing was performed in AOSD synovial tissues. RESULTS: Forty consecutive AOSD patients were assessed, 14 complicated with MAS. Paralleling with increases of systemic score and ferritin, MAS patients showed higher levels of IL-1α, IL-1ß, IL-1Ra, IL-2Ra, IL-6, IL-10, IL-17A, IFN-γ, G-CSF, MCP-1, MIP-1α and SCF. Combining the discriminatory ability of these data in identifying MAS, the best model was composed by systemic score, ferritin, IFN-γ and IL-10. By CyTOF analysis, MAS patients showed an increase of circulating 'classical monocytes' and a reduction of total NK cells. Our assessment showed 3477 IFN-related genes (IRGs) were differently expressed in AOSD synovial tissues. CONCLUSIONS: A multidimensional characterization of AOSD patients suggested that IFN-γ, IL-10, ferritin and systemic score discriminated the occurrence of cytokine storm syndrome associated with MAS. The inflammatory milieu of AOSD and MAS may be related to a signature of circulating immune cells. Finally, our results about IRGs reinforced the role of IFN-γ in these patients.

OBJECTIVE: To compare clinical features and treatments of patients with systemic JIA (sIJA) and adult-onset Still's disease (AOSD). METHODS: The clinical charts of consecutive patients with sJIA by International League of Association of Rheumatology criteria or AOSD by Yamaguchi criteria were reviewed. Patients were seen at a large paediatric rheumatology referral centre or at 10 adult rheumatology academic centres. Data collected included clinical manifestations, inflammation biomarkers, systemic score, macrophage activation syndrome (MAS), parenchymal lung disease, disease course, disability, death and medications administered. RESULTS: A total of 166 patients (median age at diagnosis 5 years) with sJIA and 194 patients with AOSD (median age at diagnosis 41 years) were included. The frequency of fever, rash, arthralgia, abdominal pain, MAS, parenchymal lung disease and increased acute phase reactants and ferritin were comparable between the two cohorts. Patients with sJIA had a higher prevalence of arthritis, whereas patients with AOSD had experienced leucocytosis and extra-articular organ involvement more frequently. Patients with AOSD were given more commonly low-dose corticosteroids, whereas biologic DMARDs were administered first-line more frequently in patients with sJIA. CONCLUSION: We found remarkable disparities in the prevalence of clinical manifestations between the two illnesses, which may partly depend on their classification by different criteria.

OBJECTIVES: In systemic sclerosis (SSc) patients, pulmonary arterial hypertension (PAH), which is preceded by pulmonary vascular disease (PVD), is one the of major causes of morbidity and mortality. Given the higher risk of PAH among anti-CENP antibodies (ACA)+ patients, we previously characterised a subset of ACA+ patients, based on a differential reactivity of their ACA with the phage clone (pc4.2)-expressing peptide 4.2 (p4.2). There was a considerably greater prevalence of a low diffusing lung capacity for carbon monoxide (DLCO), an expression of PVD, among patients with high anti-pc4.2 Ab levels. Here we examine whether a similar clinical subgroup can be identified within a larger cohort of ACA+ patients, using the synthetic p4.2. METHODS: Clinical data and serum samples were collected from 134 ACA+ patients. Sera were screened for reactivity with p4.2 by indirect ELISA. Statistical analyses were performed to define any associations between anti-p4.2 Ab levels and PVD. RESULTS: Kendall's analysis showed that anti-p4.2 Ab were directly associated with both a reduced DLCO and the presence of pulmonary fibrosis (PF). These associations were confirmed by Fisher's exact test. At multivariate analysis, anti-p4.2 Ab was associated to DLCO<70, DLCO≤60, and PF. Moreover, multivariable analysis showed that only the association of anti-p4.2 Ab with DLCO<70, and not with DLCO≤60, was independent of PF. CONCLUSIONS: Anti-p4.2 Ab are able to identify SSc patients at high risk of developing PVD even in the absence of PF. Patients with high anti-p4.2 Ab levels should be strictly monitored for PVD onset and eventually PAH.

OBJECTIVES: Long-term quality of life (QoL) is significantly compromised in patients with psoriatic arthritis (PsA) and only partially improves achieving remission or low disease activity. The main aim of this study is to evaluate the QoL in PsA patients and to investigate their possible relationship with clinical remission and low disease activity, and with its duration over time. METHODS: A multicentre cross-sectional observational study has been performed. QoL domains considered were analysed through PROs. Chi2 test was used for analysis of contingency tables, while Mann-Whitney test and Kruskal-Wallis test with Holm's pairwise comparison corrections were used to compare ranks. To evaluate variables associated to the different QoL domains, univariate and multiple linear regressions were used. RESULTS: 143 participants were included in this study. The physical component of the Short Form-36 or Functional Assessment of Chronic Illness Therapy-Fatigue tends to improve with short duration of low or minimal disease activity. However, this is not confirmed for the mental component of SF-36 (MCS), which improved only with longer duration of low/minimal disease activity. CONCLUSIONS: This study proves the existence of an inverse relation between disease activity and QoL domains. Apart from low or minimal disease activity, also its persistence over time has a great influence on the patient's perception of their clinical condition; therefore, persistence over time of clinical remission/low disease activity should be added to the latest definition of treat-to-target in PsA.

OBJECTIVES: In this study, we aimed at describing the clinical characteristics, life-threatening complications occurrence, and mortality of adult-onset Still's disease (AOSD) patients with elderly onset. METHODS: A multicentre retrospective study of prospectively followed-up AOSD patients included in Gruppo Italiano di Ricerca in Reumatologia Clinica e Sperimentale (GIRRCS) cohort was performed. RESULTS: Out of 221 assessed patients, 37 (16.7%) had an onset of the disease aged over 60 years. When compared with younger patients, these were characterised by a higher prevalence of pericarditis (p=0.008), comorbidities (p<0.0001), and mortality (p=0.023). Age predicted the presence of serositis in both univariate (HR: 1.02, 95%CI: 1.01-1.03, p=0.007) and multivariate analyses (HR: 1.02, 95%CI: 1.01-1.04, p=0.007). Age was also a significant predictor of parenchymal lung disease in both univariate (HR: 1.03, 95%CI: 1.01-1.05, p=0.017) and multivariate analyses (HR: 1.03, 95%CI: 1.00-1.05, p=0.048). Furthermore, age resulted to be a negative predictor of polycyclic pattern only in univariate analysis (HR: 0.99, 95%CI: 0.97-1.00, p=0.048). Finally, age significantly predicted the mortality in both univariate (HR: 1.03, 95%CI: 1.00-1.06, p=0.034) and multivariate analyses (HR: 1.05, 95%CI: 1.01-1.08, p=0.012). CONCLUSIONS: Clinical features of AOSD patients in the elderly were described in our cohort. Although the main clinical characteristics were similar comparing older and younger patients, patients aged over 60 years at disease onset were characterised by an increased prevalence of serositis, comorbidities, mostly cardiometabolic, and a higher mortality rate. Age predicted the presence of parenchymal lung disease and mortality, and it could be considered a negative prognostic factor in AOSD.

OBJECTIVES: In rheumatoid arthritis (RA), "traditional" cardiovascular (CV) risk factors continue to be underdiagnosed and undertreated, thus increasing the risk of developing atherosclerosis. In this work, we evaluated the occurrence and predictive factors of "traditional" cardiovascular risk factors, with a focus on high blood pressure (HBP), type 2 diabetes (T2D), and metabolic syndrome (MetS), in participants with RA, in a 3-year, multicentre, prospective, observational study. METHODS: To assess the occurrence and predictive factors of HBP, T2D, and MetS, consecutive participants with RA, admitted to Italian Rheumatology Units, were evaluated in the GIRRCS (Gruppo Italiano di Ricerca in Reumatologia Clinica e Sperimentale) cohort, a 3-year, multicentre, prospective, observational study. RESULTS: In the present evaluation, 841 participants, who were fully followed up with 3-year of prospective follow-up were assessed. At the end of follow-up, a significant increased incidence of HBP, T2D, and MetS was recorded. Assessing predictive factors, the mean values of C-reactive protein during the follow-up were independent predictors of occurrence of those comorbidities, whereas participants maintaining remission showed a significant lower risk. Furthermore, therapy with hydroxychloroquine (HCQ) reduced the risk of occurrence of T2D and MetS. CONCLUSIONS: An increased incidence of HBP, T2D, and MetS was observed in assessed participants, prospectively followed-up. Furthermore, the analysis of predictive factors suggested that the rheumatoid pro-inflammatory process could increase the occurrence of these comorbidities. Conversely, metabolic and cardiovascular benefits of maintaining remission as well as of therapy with HCQ were reported.

Rheumatoid arthritis (RA) is a chronic autoimmune disease and rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA) are the most frequently detected autoantibodies (autoAbs). To date, more than 20% of RA cases are still defined as seronegative forms (seronegative RA, SN-RA). The aim of this study was to identify new antigenic targets of autoAbs in RA patients, which can also be recognized in SN-RA. Using a proteomic approach, we tested sera from SN-RA patients by analyzing synovial fluid (SF) proteins from these patients. Sera from SN-RA patients revealed a strong reactive spot, corresponding to alpha 1 antitrypsin (A1AT). Reverse-phase nanoliquid chromatography and tandem mass spectrometry (Matrix Assisted Laser Desorption/Ionization-Time Of Flight, MALDI-TOF/TOF) confirmed the presence of A1AT in SF and showed that homocysteinylation was one of the post-translational modifications of A1AT. Homocysteinylated (Hcy)-A1AT immunoprecipitated from SN-RA patients' SFs and in vitro modified Hcy-A1AT were used as antigens by Enzyme-Linked ImmunoSorbent Assay (ELISA) to test the presence of specific autoAbs in sera from 111 SN-RA patients, 132 seropositive (SP)-RA patients, and from 95 patients with psoriatic arthritis, 40 patients with osteoarthritis, and 41 healthy subjects as control populations. We observed that a large portion of SN-RA patients (75.7%), and also most of SP-RA patients' sera (87.1%) displayed anti-Hcy-A1AT autoAbs (anti-HATA). Native A1AT was targeted at a lower rate by SP-RA patients autoAbs, while virtually no SN-RA patients' sera showed the presence of anti-native A1AT autoAbs. In conclusion, anti-HATA can be considered potential biomarkers for RA, also in the SN forms. The discovery of novel autoAbs targeting specific autoantigens can represent higher clinic significance for all RA patients' population.

Psoriatic arthritis (PsA) is a chronic inflammatory arthropathy involving synovial and entheseal structures, associated with psoriasis or similar conditions. The etiopathogenetic mechanisms underlying PsA remain unclarified. The most accredited hypothesis involves a complex interaction among genetic, environmental, and immunological factors. Environmental agents, particularly trauma, mechanical stress, and smoke have been cited as possible factors in triggering the disease in genetically predisposed subjects. Like other forms of spondyloarthropathies, PsA shows several genetic associations with the major histocompatibility complex (MHC) class I alleles located on chromosome 6p21.3, particularly the human leukocyte antigen (HLA)-B27 in axial phenotypes. Recent studies have demonstrated that the most common epigenetic mechanisms that regulate gene expression in PsA are represented by DNA methylation, parent of origin effect or genomic imprinting, expression or activity of epigenetic modifying enzymes, and RNA interference (RNAi) by microRNAs (miRNAs). The mechanisms underlying PsA pathogenesis activate the innate and adaptive immune system and overexpression of TNF associated with amplification of the IL-23/IL-17 axis. In recent years, more PsA susceptibility genes and epigenetic mechanisms have been identified. Advances in the knowledge of innate and adaptive immune mechanisms underlying PsA have contributed to a better understanding of the heterogeneous clinical expression of the disease and, thus, to therapy strategies. The complexity of the pathogenetic aspects involving multiple cytokines, cell lines, and molecules needs to be further investigated to advance personalized therapeutic strategies and to improve outcomes of patients affected by PsA.

OBJECTIVES: Axial spondyloarthritides (axSpA) are a group of disorders that share similar pathogenetic mechanisms and clinical picture. The aim of this retrospective multicentric study was to evaluate demographic and clinical differences between ankylosing spondylitis (AS) and non-radiographic axSpA (nr-axSpA) patients. METHODS: Patients from 7 rheumatological centres in the Lazio region of Italy were included from January 1st, 2010 to April 1st, 2018, if they had undergone pelvic and/or spine radiographs or magnetic resonance imaging (MRI). Images were evaluated by one experienced radiologist in each centre who already had the clinical suspicion of axSpA. Clinical and therapeutic data were collected at the last observation visit. Categorical variables were presented with percentages and analysed by Chi squared test. Continuous variables were expressed as mean ± standard deviation and compared using the parametric unpaired t-test or the non-parametric Mann-Whitney U-test, when appropriate. p-values <0.05 were considered significant. RESULTS: 210 axSpA patients were included: 65.2% with AS and 34.7% with nr-axSpA. When comparing the two groups, AS patients had longer disease duration, were older, were more frequently males, had a greater diagnostic delay and a higher body mass index than the nr-axSpA patients (p<0.0001, p<0.0001, p=0.003 p=0.007, and p=0.04, respectively). The peripheral joints of the nr-axSpA patients were more frequently involved, had higher frequency of inflammatory bowel disease, higher C-reactive protein levels and lower frequency of HLA-B27 positivity (p=0.005, p=0.007, p=0.01, and p=0.01, respectively). TNF inhibitors were used in 87.8% patients with AS and 78.3% with nr-axSpA (p=0.04). More fat metaplasia was observed on MRI in the nr-axSpA group than in the AS group at sacroiliac joints (p=0.003), and more backfills were detected in the AS group on spine-MRI (p=0.003). Spine-bone marrow oedema was more prevalent in AS than in nr-axSpA (p=0.04), and more sclerosis and backfill were found in AS (p=0.003 and p=0.01, respectively). CONCLUSIONS: In clinical practice, distinctive features in AS and nr-axSpA patients emerged.

Diet is a modifiable factor implicated in chronic systemic inflammation, and the mediterranean dietary pattern is considered to be a healthy model in terms of morbidity and mortality. The main aim of this study was to evaluate the adherence to the mediterranean diet in patients with Psoriatic Arthritis (PsA) and its impact on disease activity. A cross-sectional observational study was conducted in a cohort of 211 consecutive PsA patients. We evaluated PsA activity by disease activity index for PSoriatic Arthritis (DAPSA) and composite psoriatic disease activity index (CPDAI). The NCEP-ACT III criteria were used to identify subjects with MetS, and in each subject, we evaluated body mass index (BMI). A validated 14-item questionnaire for the assessment of adherence to the mediterranean diet (PREDIMED) was recorded for all the enrolled subjects. Patients showed a median age of 55 (48-62) and diseaseâ¯duration was 76 (36-120) months. 27.01% of patients were classified as having MetS. The median of the mediterranean diet score (MDS) was 7 (6-9). A moderate adherence to mediterranean diet was found in 66.35% of the entire cohort; 15.64% and 18.01% of the patients showed low- and high adherence to the dietary pattern, respectively. We found a negative association between DAPSA and adherence to mediterranean diet (B = - 3.291; 95% CI - 5.884 toâ¯- 0.698). DAPSA was positively associated with BMI (B = 0.332; 95% CI 0.047-0.618) and HAQ ( B = 2.176; 95% CI 0.984-3.368). Results from our study evidenced that in PsA patients, higher levels of disease activity as measured by DAPSA correlated with low adherence to mediterranean diet, suggesting potential benefit of antinflammatory properties of this dietary pattern.

OBJECTIVES: To identify the distribution of patients with systemic lupus erythematosus (SLE) in clusters according to the levels of health-related quality of life (HRQoL), entity of pain, fatigue and depression. METHODS: We performed a hierarchical cluster analysis. The following measures were used as clustering variables, after canonical transformation: the SF36 physical and mental component summary (PCS and MCS), the Beck Depression Inventory II (entity of depression), the Facit-Fatigue, all assessed during the last visit. Consecutive SLE patients were enrolled from two Italian cohorts. Lupus remission was retrospectively assessed over a period of 5 years before the last visit and was defined as a continuative period of no clinical disease activity according to SLEDAI2K and the maximum dose of prednisone allowed of 5 mg/day. RESULTS: We enrolled 130 female SLE patients. We identified three clusters. The first cluster (43 patients) was characterised by the highest levels of MCS and PCS and the lowest entity of pain, fatigue and depression. Cluster 2 (35 patients) was defined by a reduction of MCS and increase of pain, fatigue and depression; conversely, PCS levels were similar to cluster 1. In cluster 3 (52 patients) we found a reduction of MCS and increase of depression and fatigue (similar to cluster 2) but also a decrease in PCS levels and Bodily Pain (meaning increase in pain). In cluster 3 we found a decreased prevalence of remission ≥5 years. CONCLUSIONS: Identification of clusters of patients according to HRQoL levels could be useful to improve SLE management, aiming at personalised medicine.

OBJECTIVE: In SSc, vascular injury leads to endothelial dysfunction with reduced capillary blood flow and tissue hypoxia. In SSc, the angiogenesis is impaired and implicated in the microvascular damage. In severe vascular damage, VEGF is reduced and endostatin is increased. The aim of this study was to evaluate the correlation between endostatin serum levels and microvascular and digital arteries damage. METHODS: Seventeen patients with SSc were enrolled in this study. Serum endostatin levels were determined. All patients underwent a NVC, CDUS, and LDPI. RESULTS: The serum level of endostatin significantly (P < .05) increased with NVC progression damage. The mean perfusion significantly (P < .05) decreased with NVC progression damage. Multiple regression analysis showed a significant correlation between endostatin serum level and RI (r = .34, P < .05), PI (r = .60, P < .01), S/D ratio (r = .76, P < .0001), and mean perfusion (r = -.68, P < .001). Endostatin serum levels significantly (P < .05) increased with progression of CDUS damage. CONCLUSIONS: Increased serum endostatin levels are associated with digital vascular damage. In patients with SSc, endostatin is a marker of skin perfusion and digital arteries damage of hands.

OBJECTIVES: The imbalance between angiogenic and angiostatic factors with derangement of the microvasculature are hallmarks of systemic sclerosis (SSc). Raynaud's phenomenon in SSc probably is due to the impaired neuroendothelial control mechanisms between vasoconstriction and vasodilatation. The aim of this study is to evaluate autonomic nervous system function using heart rate variability (HRV) analysis and to correlate with vascular endothelial growth factor (VEGF). METHODS: Twenty-seven SSc patients were enrolled. HRV was measured and markers of global sympathetic and parasympathetic system, respectively standard deviation of normal-to-normal RR intervals (SDNN) and square root of the mean of the sum of the squares of differences between adjacent NN intervals (RMSSD) were evaluated. Serum VEGF levels and nailfold videocapillaroscopy (NVC) were performed. RESULTS: A linear positive correlation was observed between RMSSD and VEGF (p<0.01, r=0.55), and RMSSD and disease duration (p< 0.01, r=0.54). The RMSSD median value was significantly increased (p< 0.05) with NVC damage progression. The RMSSD median value was significantly (p<0.05) higher in SSc patients with digital ulcers (DUs) than in SSc patients without DUs [44 (39.4-60.2) vs 24.6 (23-37.1)]. CONCLUSIONS: In our study parasympathetic modulation increases in relation to VEGF. When microcirculation is modified with capillaroscopic pattern progression and DUs, autonomic system seems to stimulate vasodilatation trough parasympathetic system. We can conclude that parasympathetic activity increases with digital microvascular damage and promotes VEGF release.
