PURPOSE To examine the impact of golimumab, on work productivity, activity limitation, and quality of life (QoL) in patients with axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA). METHODS This real-world, multicenter, prospective study consecutively enrolled adult consented work-active patients with axSpA or PsA, newly initiated on golimumab as per the approved label. Prior receipt of > 1 prior biologic, or switching from another tumor-necrosis factor inhibitor due to primary non-response or safety reasons was not allowed. The Work Productivity and Activity Impairment-Specific Health Problem and the EuroQol 5-Dimensions (EQ-5D)-5-Level instruments were completed by the patients to assess the impact of golimumab on work productivity and activity impairment, and generic QoL, respectively. RESULTS Overall, 121 eligible patients (mean age: 45.4 years; median disease duration: 11.3 months), 51 diagnosed with PsA and 70 with axSpA, were enrolled by 19 rheumatologists. Over a 11.9-month median observation period

Microvascular dysfunction is the key element in the pathogenesis of systemic sclerosis (SSc), whereas the contribution of large and medium size vessel abnormalities is yet to be established. The aim of the present study is to assess the association between micro- and macrovascular function by utilizing a broad spectrum of assessments of vascular performance.We included consecutive, consenting SSc patients who underwent nailfold video capillaroscopy (NVC) for microcirculation evaluation. Peripheral and central systolic and diastolic blood pressure, carotid intima-media thickness (cIMT), aortic augmentation index (AIx) corrected for a heart rate of 75 beats per minute (AIx-75), and carotid-femoral pulse wave velocity (PWV) were also performed to assess macrovascular function. Cardiovascular risk disease (CVD) algorithms were also calculated and included in the analysis.A total of 81 patients (6 males) were studied with mean age 55.44 ± 13.40 years. Reduced capillary density was inversely correlated with arterial stiffness (Alx-75) and augmentation pressure (r = - 0.262, p = 0.018, and r = - 0.249, p = 0.025 respectively). Alx was significantly lower in the early compared to late pattern (28.24 ± 11.75 vs 35.63 ± 10.47, p = 0.036). A significant trend was found among NVC patterns with Alx-75 values being higher with the progression of microangiopathy towards the "late" group (26.36 ± 10.90 vs 30.81 ± 11.59 vs 35.21 ± 7.90, p = 0.027 for trend). Similarly, Framingham risk score and Atherosclerotic Cardiovascular Disease score were progressively higher across the worsening NVC patterns (4.10 ± 4.13 vs 2.99 ± 2.72 vs 6.36 ± 5.65, p = 0.023, and 6.99 ± 7.18 vs 5.63 ± 4.41 vs 12.09 ± 9.90, p = 0.019, respectively, for trends). Finally, QRISK3 (10-year cardiovascular disease risk) and ASCVD (Atherosclerotic Cardiovascular Disease) scores were inversely correlated with the number of capillaries (r = - 0.231, p = 0.048, and r = - 0.260, p = 0.038 respectively).These data suggest that CVD risk scores and macrovascular parameters are strongly correlated with microvasculopathy in patients with SSc. Key Points • Microangiopathy is the hallmark of SSc, but the relationship between subclinical atherosclerosis and small vessel disease remains unknown. • Arterial stiffening and CVD risk scores are positively associated with the degree of progression of peripheral microvasculopathy assessed with NVC. • The results of the study suggest an association between NVC abnormalities and higher CVD risk in SSc patients.

Systemic sclerosis (SSc) is characterized by generalized vasculopathy affecting mainly small vessels while macrovascular involvement is less investigated. The aim of this study was to examine associations between asymmetric dimethylarginine (ADMA) - a biomarker of atherosclerosis - and assessments of macrovascular endothelial function in patients with SSc.This was a cross-sectional study including consecutive SSc patients attending the Scleroderma Outpatient Clinic. ADMA measurement in serum samples was based on an enzyme immunoassay technique. Participants underwent blood pressure measurement according to 2018 ESC/ESH Guidelines, applanation tonometry for the evaluation of arterial stiffness, and carotid ultrasound for the measurement of the intima-media thickness (cIMT).Eighty-one Caucasians (82.3% female) SSc individuals with mean age 55.44 ± 13.4 years were included in this analysis. The correlation analysis of ADMA levels (unadjusted and adjusted values) with functional and morphological parameters of atherosclerosis revealed no statistically significant associations. Subgroup analysis based on disease duration (≤ 4 years), immunologic profile (SCL-70 and ACA antibodies), disease type (limited, diffuse), and inflammatory status (erythrocyte sedimentation rate [ESR] 25 mm/h and C-reactive protein [CRP] 5 mg/L) showed no associations, except from a significant positive correlation between ADMA levels and cΙΜΤThe results of the study suggest that ADMA may be related with accelerated atherosclerosis in early stages of the disease. However, the lack of association between other morphological and functional parameters of endothelial dysfunction may suggest that other regulators of nitric oxide metabolism may contribute to macrovascular injury in SSc in various phases of the disease. Key Points • ADMA is a biomarker of atherosclerosis and has been linked with microvascular complications of SSc. •ADMA was not correlated with morphological and functional parameters of atherosclerosis in the population of the study. •The demonstrated association between ADMA and cIMT in patients with early SSc may suggest a role of NO/ADMA pathway in the initiation of macrovascular injury in SSc.

Rheumatoid Arthritis (RA) is a chronic systemic autoimmune disease that primarily affects synovial joints and is associated with increased cardiovascular (CV) mortality and morbidity. This association is only partially attributed to the presence of classic CV disease risk factors, and is strongly associated with characteristics of disease itself namely systemic chronic inflammation and autoimmune activation. Growing evidence suggests that microvascular endothelial dysfunction contributes to the initiation and progression of vascular disease. Nailfold capillaroscopy is a non-invasive method that evaluates the morphology and the structure of nailfold capillaries. Extension of this method is the Nailfold Videocapillaroscopy (NVC), which provides the possibility of combining functional and anatomical study of peripheral microcirculation. The present cross-sectional study aims to evaluate using NVC the peripheral microcirculation in adult patients with RA and investigate the associations between structural and functional indices of digital capillaries with markers of atherosclerosis.

Objectives Predicting serious infections (SI) in patients with rheumatoid arthritis (RA) is crucial for the implementation of appropriate preventive measures. Here we aimed to identify risk factors for SI and to validate the RA Observation of Biologic Therapy (RABBIT) risk score in real-life settings. Methods A multi-centre, prospective, RA cohort study in Greece. Demographics, disease characteristics, treatments and comorbidities were documented at first evaluation and one year later. The incidence of SI was recorded and compared with the expected SI rate using the RABBIT risk score. Results A total of 1557 RA patients were included. During follow-up, 38 SI were recorded [incidence rate ratio (IRR): 2.3/100 patient-years]. Patients who developed SI had longer disease duration, higher HAQ at first evaluation and were more likely to have a history of previous SI, chronic lung disease, cardiovascular disease and chronic kidney disease. By multivariate analysis, longer disease duration (IRR: 1.05; 95% CI: 1.005, 1.1), history of previous SI (IRR: 4.15; 95% CI: 1.7, 10.1), diabetes (IRR: 2.55; 95% CI: 1.06, 6.14), chronic lung disease (IRR: 3.14; 95% CI: 1.35, 7.27) and daily prednisolone dose ≥10 mg (IRR: 4.77; 95% CI: 1.47, 15.5) were independent risk factors for SI. Using the RABBIT risk score in 1359 patients, the expected SI incidence rate was 1.71/100 patient-years, not different from the observed (1.91/100 patient-years; P = 0.97). Conclusion In this large real-life, prospective study of RA patients, the incidence of SI was 2.3/100 patient-years. Longer disease duration, history of previous SI, comorbidities and high glucocorticoid dose were independently associated with SI. The RABBIT score accurately predicted SI in our cohort.

Systemic sclerosis (SSc) is a connective tissue disease characterized primarily by micro-angiopathy and endothelial dysfunction which stimulate a fibrotic process. Asymmetric dimethylarginine (ADMA) is an endogenous nitric oxide (NO) inhibitor and represents a novel biomarker for vascular dysfunction. Nailfold video capillaroscopy (NVC) represents a non-invasive and reliable technique for the evaluation of microvasculopathy in SSc.The aim of this study was to examine the possible association between ADMA and microvascular involvement in patients with SSc.This was a cross-sectional study including consecutive SSc patients attending the Scleroderma Outpatient Clinic. ADMA was measured in serum samples using a commercial enzyme immunoassay. Participants underwent NVC with qualitative and semi-quantitative assessment and all NVC parameters were measured in the distal row of each finger. The findings were classified in one of the three qualitative NVC patterns: early, active, and late.Eighty-one (92,6 % women) SSc individuals with mean age 55.44 ± 13.4 years were included in this analysis. Within-groups comparisons revealed a trend between higher ADMA levels and progressive micro-vasculopathy (1,29 [2,1] vs 1,57 [1,95] vs 2,41 [3,87]; for early, active and late patterns respectively, p = 0.039). Furthermore, ADMA concentration was significantly associated with the number of capillaries/mm (r = -0.235; p = 0.035).Serum ADMA levels were significantly associated with advancing stages of microcirculatory abnormalities suggesting that ADMA may have a role in promoting microvascular endothelial dysfunction in SSc individuals.

Increased arterial stiffness is independently associated with renal function decline in patients with diabetes mellitus (DM). Whether DM has additional deleterious effects on central hemodynamics and arterial stiffness in chronic kidney disease (CKD) patients is yet unknown. This study aimed to compare ambulatory central BP, arterial stiffness parameters, and trajectories between patients with diabetic and non‐diabetic CKD. This study examined 48 diabetic and 48 non‐diabetic adult patients (>18 years) with CKD (eGFR

Nailfold videocapillaroscopy (NVC) changes in systemic sclerosis (SSc) are correlated with vascular complications, such as pulmonary arterial hypertension (PAH), supporting a potential link between peripheral and internal organ vasculopathy. The current stage of knowledge regarding NVC and PAH is discussed, focusing on the assessment of peripheral microangiopathy and a potential relationship with functional, echocardiographic, and haemodynamic markers of cardiac dysfunction. A comprehensive literature search was carried out to identify all studies focusing on NVC findings in patients with PAH, diagnosed with right heart catheterization. The majority of the studies examined NVC findings in patients with SSc-PAH, while three studies reported NVC abnormalities in patients with idiopathic PAH. Besides the pulmonary vasculature, a systemic component of microangiopathy seems to be involved in PAH. Well-designed prospective trials are warranted to validate NVC as a biomarker, with clinical implications in the diagnostic evaluation, risk stratification, and overall management of PAH in the daily clinical setting.

Systemic autoimmune inflammatory disorders confer a higher risk of cardiovascular (CV) disease leading to increased morbidity and mortality and reduced life expectancy compared to the general population. CV risk in systemic sclerosis (SSc) has not been studied extensively but surrogate markers of atherosclerosis namely carotid intima media thickness (cIMT) and pulse wave velocity (PWV) are impaired in some but not all studies in SSc patients. The aim of this study was to investigate the prevalence of subclinical atherosclerosis assessed by cIMT and PWV between two well-characterized SSc and Rheumatoid Arthritis (RA) cohorts. Consecutive SSc patients attending the Scleroderma Clinic were compared with RA patients recruited in the Dudley Rheumatoid Arthritis Co-morbidity Cohort (DRACCO), a prospective study examining CV burden in RA. Augmentation Index (Aix75) and cIMT were measured in all participants. Propensity score matching was utilised to select patients from the two cohorts with similar demographic characteristics, CV risk factors and inflammatory load. Unpaired analysis was performed using unpaired t test for continuous variables and χ2 test for dichotomous variables. Statistical analysis was repeated using paired t test for continuous normal variables and McNemar’s test for dichotomous variables. Fifty five age- and sex-matched SSc and RA patients were included in the analysis. No difference was demonstrated between SSc and RA subjects regarding cIMT (0.66 mm vs 0.63 mm, respectively) and Aix75% measurements (33.4 vs 31.7, respectively) neither in paired (p = 0.623 for cIMT and p = 0.204 for Aix%) nor in unpaired t test analysis (p = 0.137 for cIMT and p = 0.397 for AIx%). The results of this comparative study show that subclinical atherosclerosis is comparable between SSc and RA, a systemic disease with well-defined high atherosclerotic burden. Such findings underscore the importance of CV risk management in SSc in parallel with other disease-related manifestations.

Systemic sclerosis (SSc) is a systemic inflammatory, autoimmune disorder characterized by diffuse fibrosis of the skin and visceral organ involvement. Endothelial dysfunction and microvascular injury dominate the pathophysiology and clinical manifestations of the disease, while the impact of macrovascular atherosclerotic disease on cardiovascular (CVD) morbidity and mortality is yet to be established. In this article, we aim to review current knowledge about CVD as well as cardiac complications in SSc and discuss the potentially implicated pathogenetic mechanisms. Systemic inflammation has been identified as an important trigger and contributor for the development and progression of atherosclerosis, closely associated with high cardiovascular mortality in patients with autoimmune disorders, such as rheumatoid arthritis. A close interplay between traditional risk factors and factors related to the disease, including inflammation, endothelial injury, and immune-mediated cytotoxicity, sharing common pathogenetic features with microvasculopathy, may be responsible for large-vessel involvement and promotion of atherosclerosis in SSc. Cardiac complications, including heart failure due to impairment of coronary microcirculation and myocardial fibrosis, are listed among the primary cause of death in SSc. Evaluation of indirect surrogate markers of CVD, namely, arterial stiffness, carotid media thickness, and flow-mediated dilation, in small studies has provided inconsistent results regarding the association between SSc and atherosclerosis, highlighting the need for further research on this field. In this article, we aim to review current knowledge about large-vessel involvement and CVD in SSc and discuss the potentially implicated pathogenetic mechanisms. SSc conveys a higher risk for CVD associated with both vascular and fibrotic complications during the course of the disease. Increasing attention is given on the use of vasodilators, immunosuppressants, and more recently antifibrotic drugs that potentially improve myocardial function and reduce atherosclerotic disease burden.

Rheumatoid arthritis (RA) is a systemic inflammatory disease treated with conventional and biologic disease-modifying drugs. Methotrexate is the anchor drug for the treatment of RA and is also frequently used for various autoimmune diseases. Adverse events are common and generally easy to manage, involving mainly the gastrointestinal tract and the liver function. However, neurotoxicity is very uncommon in adults with rheumatic diseases. B cell depletion with rituximab is another therapy approach particularly in patients with refractory RA. Whistle leukoencephalopathy - namely progressive multifocal leukoencephalopathy-is an infrequent but well-described side effect of rituximab. In contrast, central nervous system toxicity due to methotrexate is extremely rare especially in RA individuals under oral or subcutaneous low dose on weekly basis. We present a challenging case of a RA patient on treatment with methotrexate and rituximab presenting with leukoencephalopathy. The patient was diagnosed with methotrexate-induced leukoencephalopathy which reversed after treatment discontinuation. We comment on the symptoms and diagnostic workout and we review the available literature on this issue based on recommendations for narrative reviews.

EBV infection has long been suspected to play a role in the development of autoimmune diseases. Interestingly, a recently published study has provided the strongest evidence to date that EBV is truly a trigger for multiple sclerosis, a well known inflammatory and neurodegenerative autoimmune disorder. Taking into account the data derived from mice models of autoimmune diseases that were also infected with a murine analog of EBV, in this commentary, we highlight the involvement of age-associated B cells, a B cell population defined as CD19

Lupus nephritis (LN) affects a significant proportion of patients with systemic lupus erythematosus (SLE) and is characterised by increased morbidity and mortality. The updated joint EULAR/European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) recommendations for the management of LN have set as target of therapy the optimisation (preservation or improvement) of kidney function, accompanied by a reduction in proteinuria of at least 25% by 3 months, 50% by 6 months, and below 500-700 mg/g by 12 months (complete clinical response). It is currently unknown what proportion of Greek patients with LN reach these proposed targets with the current available treatments. At the same time, recent successful phase 3 trials have led to the approval of both belimumab and voclosporin for the treatment of patients with LN and have steered discussions as to whether the "induction-maintenance" paradigm should be substituted by an early combination treatment for all patients. To inform future therapeutic decisions and facilitate the positioning of these new drugs in the therapeutic algorithm of LN, the current study protocol aims to map the unmet needs in the treatment of LN in Greece, by quantifying the proportion of patients who attain the recommended treatment targets in everyday clinical practice.

Background Listeria monocytogenes is an opportunistic pathogen that causes severe infections of the Central Nervous System, such as meningitis or meningoencephalitis, and brain abscesses. Abscesses account for approximately 1-10% of CNS listerial infections and are observed in 1% of all listerial infections. Methods We describe a case of 70-year-old male patient who had several admissions in different hospitals over the last 8 weeks. Results He suffered from intermittent fever for over a month, recurrent episodes of headaches, disorientation and other neurological symptoms. His condition was misdiagnosed as giant cell arteritis and initially the patient was started on corticosteroids. MRI of the brain revealed the presence of multiple brain abscesses and the cerebrospinal fluid study confirmed the presence of Listeria Monocytogenes. The patient was started on ampicillin and he completed a 6 weeks' course of treatment. Conclusions This case emphasizes the need to include rare pathogens in the differential diagnosis when possible CNS infections are involved, as well as to show that in many cases some auto-immune diseases are overdiagnosed.

The therapeutic armamentarium in Systemic Lupus Erythematosus (SLE) is expanding with the introduction of novel biologic and small-molecule agents. Complementary to randomized controlled trials, registry-based studies are advantageous due to the inclusion of a wider range of patients from daily practice and the potential for long-term monitoring of the efficacy and safety of therapies. Moreover, data from registries can be used to identify disease phenotypes that best respond to biologic agents, and to correlate clinical response with parameters such as co-administered therapies and comorbidities. In this project, we will use the configuration of the Hellenic Registry of Biologic Therapies for inflammatory arthritides in order to design a dedicated SLE module with variables pertaining to global and organ-specific disease activity, severity, flares, organ damage/outcome, comorbidities and adverse events. The second stage will involve the pilot implementation of this platform for the multicentric registration of SLE patients who are treated with belimumab. The significance lies in the development of a structured registry that enables the assessment of the disease burden and the long-term efficacy and safety of existing and future biological agents in SLE. Piloting the registry can serve as a basis for establishing nationwide collaborative efforts.

Pulmonary arterial hypertension (PAH) represents one of the most devastating complications in connective tissue diseases (CTDs). The aim of this study was to investigate the presence of peripheral microangiopathy in patients with PAH associated with CTDs (CTD-PAH) by exploring nailfold videocapillaroscopic (NVC) changes and identify possible associations of NVC characteristics with markers of disease severity. Α cross-sectional study was performed in 18 CTD-PAH patients [13 PAH due to systemic sclerosis (SSc-PAH) and 5 with other types of CTD-PAH], 14 patients with SSc without PAH (SSc-non-PAH) and 20 healthy controls. NVC quantitative and qualitative parameters were evaluated using Optilia Digital Capillaroscope. To ensure inter-observer repeatability, capillaroscopic images were reviewed by two independent investigators. When compared to healthy controls, patients with CTD-PAH (77.8% women, mean age 65.9 years) presented reduced capillary density (6.5 ± 1.6 loops/mm vs. 9.7 ± 0.7 loops/mm, p

Background Although pulmonary vascular bed has been the main subject of research for many years in pulmonary hypertension (PH), interest has recently started to divert towards the possibility of a co-existing peripheral microangiopathy. The aim of the current study was to investigate the presence of nailfold video-capillaroscopic (NVC) structural changes in patients with precapillary PH and to identify possible associations of NVC measurements with markers of disease severity. Methods Α prospective case–control study was performed in 28 consecutive patients with precapillary PH [14 with idiopathic pulmonary arterial hypertension (IPAH) and 14 with chronic thromboembolic pulmonary hypertension (CTEPH)] and 30 healthy controls. NVC quantitative and qualitative parameters were evaluated using Optilia Digital Capillaroscope. To ensure inter-observer repeatability capillaroscopic images were reviewed by two independent investigators. For multiple comparisons among continuous variables, one-way ANOVA or the Kruskal–Wallis test were used. Differences between the groups were tested with post-hoc analysis with adjustment for multiple comparisons (Bonferroni test). Results Both IPAH (71.4% were women, mean age 53.1 ± 13.4 years) and CTEPH (64.3% women, mean age 60.9 ± 14.4 years) groups presented reduced capillary density compared to healthy controls (8.4 ± 1.2 loops/mm and 8.0 ± 1.2 loops/mm vs. 9.7 ± 0.81 loops/mm, p Conclusion The findings of the study reveal a degree of significant peripheral microvascular alterations in patients with IPAH and CTEPH, suggesting a generalized impairment of peripheral microvasculature in pulmonary vascular disease.

Introduction: Systemic sclerosis (SSc) is associated with a heightened cancer risk compared to the general population. Several pathways including immune system upregulation, cumulative inflammation, environmental factors, and genetic predisposition contribute to the development of both cancer and autoimmunity. Areas covered: This paper provides an overview of studies investigating the relationship between SSc and various types of cancer with a special focus on the identification of patients at higher risk for malignancy development. The demographic, serological, clinical, and disease-related characteristics of SSc individuals who are diagnosed with cancer over the course of their disease are discussed to provide a practical guidance for relevant screening strategies. Expert opinion: Several studies have identified subgroups of SSc patients at higher cancer risk based on the immunological profile (anti-RNAPol III positivity), diffuse disease type, and older age at SSc onset. Additionally, a close temporal association between SSc and cancer onset in certain antibody subsets raises the question as to whether more aggressive screening strategies should be considered. Currently, there are no published studies investigating the cost-effectiveness, efficacy, and safety of a targeted cancer-detection program. Screening procedures should at least follow recommendations for the general population with a special focus on patients at higher risk and specific cancer types.

Background: Although pulmonary vascular bed has been the main subject of research for many years in pulmonary hypertension (PH), interest has recently started to divert towards the possibility of a co-existing peripheral microangiopathy. The aim of this study was to investigate the presence of peripheral microangiopathy in patients with precapillary pulmonary hypertension by exploring nailfold video-capillaroscopic (NVC) structural changes among various subgroups with precapillary PH and to identify possible associations of NVC characteristics with markers of disease severity. Methods: Α cross-sectional study was performed in 46 consecutive patients with precapillary PH [14 with idiopathic pulmonary arterial hypertension (IPAH), 18 with PAH associated with connective tissue diseases (CTD-PAH) and 14 with chronic thromboembolic pulmonary hypertension (CTEPH)] and 30 healthy controls. NVC quantitative and qualitative parameters were evaluated. Results: Patients with precapillary PH (71.7% were women, mean age 60.8 ± 13.4 years) presented reduced capillary density compared to healthy controls (7.5 ± 1.6 loops/mm vs. 9.7 ± 0.81 loops/mm, p10 (NT-proBNP) was independently associated with capillary density in patients with precapillary PH [r= -0.68, B= -1.9, 95% CI (-3,3, -0.4) p=0.014].Conclusion: Significant NVC microvascular changes were detected in patients with various types of precapillary PH, suggesting an impaired peripheral microcirculation associated with right ventricular remodeling parallel to pulmonary vasculopathy.

Background: Data regarding the real-life predictors of low disease activity (LDA) in rheumatoid arthritis (RA) patients are limited. Our aim was to evaluate the rate and predictors of LDA and treatment patterns in RA. Methods: This was a multicenter, prospective, RA cohort study where patients were evaluated in two different time points approximately 12 months apart. Statistical analysis was performed in order to identify predictors of LDA while patterns of disease-modifying anti-rheumatic drug [DMARDs; conventional synthetic (csDMARD) or biologic (bDMARD)] and glucocorticoid (GC) use were also recorded. Results: The total number of patients included was 1317 (79% females, mean age: 62.9 years, mean disease duration: 10.3 years). After 1 year, 57% had achieved LDA (DAS28ESR3.2), 21% initiated (among csDMARDs users) and 22% switched (among bDMARDs users) their bDMARDs. Conclusion: In a real-life RA cohort, during 1 year of follow-up, 43% of patients do not reach treatment targets while only ~20% of those with active RA started or switched their bDMARDs. Male sex, younger age, lower HAQ, body mass index and co-morbidity index were independent factors associated with LDA while use of GCs or ⩾2 bDMARDs were negative predictors.

Eisenmenger syndrome (ES) comprises a severe phenotype of pulmonary arterial hypertension characterized by angiopathy of the lung circulation. The aim of the present study was to demonstrate the presence of systemic microvascular abnormalities in patients with ES using nailfold video-capillaroscopy (NVC) and to identify potential correlations of nailfold capillaroscopic characteristics with non-invasive markers of systemic organ function.Α cross-sectional NVC study was performed in 17 consecutive patients with ES and 17 healthy controls matched for age and sex. NVC quantitative (capillary density, capillary dimensions, haemorrhages, thrombi, shape abnormalities) and qualitative (normal, non-specific or scleroderma pattern) parameters were evaluated.Patients with ES [median age 40 (18-65) years, 11 women] presented reduced capillary density [8.8 (7.2-10.2) loops/mm vs. 9.9 (8.3-10.9) loops/mm, p = .004] and increased loop width [15.9 (10.3-21.7) μm vs. 12.3 (7.6-15.2) μm, p.001], while they had significantly more abnormal capillaries than healthy controls [2.5 (0.9-5.4) abnormal loops/mm vs. 1.0 (0.0-1.7) abnormal loops/mm, p.001]. NVC shape abnormalities in ES were positively correlated with NT-proBNP (r = 0.52, p = .03) and were negatively associated with estimated glomerular filtration rate (r = -0.60, p = .02). Additionally, capillary loop diameter was positively correlated with increased haemoglobin levels (r = 0.55, p = .03) and negatively correlated with reduced peripheral oxygen saturation (r = - 0.56, p = .02).This study supports the hypothesis of peripheral microvascular involvement in ES parallel to pulmonary microangiopathy detected by NVC. Further longitudinal studies are needed to confirm our preliminary results.

Background and Aims Blood pressure variability (BPV) is an important risk factor for cardiovascular events and mortality in patients with chronic kidney disease (CKD). Previous evidence suggests that BPV is gradually increasing across CKD stages. Whether type 2 diabetes mellitus (DM) is an additional risk factor for increased BPV has never been studied. The aim of this study is to examine in comparison BPV in diabetic and non-diabetic patients with CKD. Method We included 48 diabetic and 48 non-diabetic adult patients (>18 years) with CKD (eGFR: Results In total population, ambulatory systolic BP (SBP) levels were significantly higher in diabetics compared to non-diabetic counterparts in all studied periods. No significant differences were evidence for ambulatory diastolic BP (DBP) in total or across CKD stages. In total, 24-hour SBP SD (15.43±4.34 vs 13.38±3.35, p=0.011), wSD (14.41±4.11 vs 12.53±3.19, p=0.014) and ARV (10.94±2.75 vs 9.46±2.10, p=0.004) were higher in patients with DM compared to those without DM. In addition, 24hour DBP SD (11.04±2.39 vs 9.80±2.28, p=0.010), wSD (10.30±2.52vs 9.05±1.99, p=0.008), CV (14.77±3.05 vs 13.14±2.96, p=0.009) and ARV (8.23±2.10 vs 7.10±1.33, p=0.002) were again different between groups. Across CKD stages 2 and 3a, BPV indices were insignificantly higher in patients with DM. In CKD Stage 3b, 24-hour SBP-SD (16.30±4.52 vs 11.35±2.62, p=0.003), wSD (15.42±4.54 vs 10.77±2.30, p=0.004), ARV (12.46±3.19 vs 8.34±2.07, p=0.001) and 24-hour DBP-CV (14.84±3.63 vs 12.18±1.91, p=0.035) were higher in diabetic compared to non-diabetic patients. In contrast, no difference between groups existed in CKD Stage 4. Conclusion Patients with DM present increased BPV in CKD Stages 2, 3a and 3b (moderately impaired renal function). This difference is not apparent in patients with advanced CKD at Stage 4.

Background and Aims Αlterations in endothelial function and capillary circulation have been associated with increased cardiovascular events and overall mortality. Both diabetes mellitus (DM) and chronic kidney disease (CKD) have been associated with microcirculatory damage. Nailfold video-capillaroscory can provide a thorough assessment of capillary density and microcirculation changes. This is the first study examining in comparison microcirculatory function parameters in diabetic and non-diabetic patients with CKD. Method We included 48 diabetic and 48 non-diabetic adult patients (>18 years) with CKD (eGFR: Results Baseline demographic, anthropometric and laboratory characteristics were similar between patients with and without diabetes in total and in CKD stages. Overall, no significant differences at baseline capillary density were observed between groups; however diabetic patients presented significantly lower capillary density during reactive hyperemia (36.3±3.8 vs 38.3±4.3 capillaries/mm2, p=0.022) and at venous congestion (37.8±4.0 vs 39.8±4.2 capillaries/mm2, p=0.015). When stratified according to CKD stages, the between-group differences in parameters of interest were not significant in stages 2, 3a and 4. In stage 3b, capillary density was significantly lower in diabetic compared to non-diabetic subjects at baseline (31.1±2.8 vs 33.4±3.4 capillaries/mm2, p=0.044), during postocclusive hyperemia (36.8±2.7 vs 40.0±4.3 capillaries/mm2, p=0.037) and venous congestion (38.3±2.8 vs 41.5±3.5 capillaries/mm2, p=0.022). Conclusion Capillary density during postocclusive reactive hyperemia and after venous congestion is lower in diabetic compared to non-diabetic CKD patients, a finding indicative that diabetes is an additional factor contributing to microcirculatory functional impairment in CKD. These differences are more prominent in CKD stage 3b, and less prominent in earlier and later stages.

Cardiovascular disease is the main cause of mortality in chronic kidney disease (CKD). Endothelial dysfunction and capillary rarefaction are established cardiovascular risk factors. Nailfold video capillaroscopy provides a thorough assessment of capillary density and functional reserve. This study aimed to examine possible differences in structural and functional capillary density in CKD stages 2–4 with nailfold video capillaroscopy. Ninety-six CKD patients, divided into four equally sized groups according to CKD stage (2, 3a, 3b, 4), underwent nailfold video capillaroscopy, during which capillary density was measured at baseline, after 4-min arterial occlusion and after 2-min venous occlusion. Arterial stiffness and wave parameters were measured with applanation tonometry and common carotid intima-media thickness (ccIMT) with ultrasound. Baseline capillary density showed a progressive reduction with advancing CKD stages (stage 2: 32.6 ± 2.8, stage 3a: 31.2 ± 3.8, stage 3b: 32.5 ± 3.3, stage 4: 28.5 ± 3.1, p = 0.011). Similar reductions were observed during postocclusive hyperemia (39.4 ± 3.0, 37.6 ± 4.2, 38.4 ± 3.8, and 33.8 ± 3.3, respectively; p = 0.021) and after venous congestion (41.1 ± 3.1, 39.0 ± 4.4, 39.9 ± 3.5, and 35.2 ± 3.4; p = 0.032). Office PWV and ccIMT showed nonsignificant increasing trends with advancing CKD. In multivariate analysis, eGFR showed a positive association (per ml/min increase; β: 0.053, 95% CI: 0.004–0.101), whereas diabetes (β: −1.706, 95% CI: −3.176 to −0.236) and parathyroid hormone (PTH) (per pg/ml increase; β: −0.022, 95% CI: −0.036 to −0.008) had negative associations with postocclusive capillary density. Both structural and functional capillary density progressively decrease with advancing CKD stages. Apart from reduced eGFR, diabetes and increased PTH levels are independently associated with this reduction. This capillary rarefaction may largely contribute to the increased cardiovascular risk of CKD patients.

Objectives Evidence on comorbidity prevalence in antiphospholipid syndrome (APS) and its difference from high comorbidity burden rheumatic diseases is limited. Herein, we compare multiple comorbidities between APS and RA. Methods A total of 326 patients from the Greek APS registry [237 women, mean age 48.7 (13.4) years, 161 primary APS (PAPS), 165 SLE-APS] were age/sex matched (1:2 ratio) with 652 patients from a Greek multicentre RA cohort of 3115 patients. Prevalence of cardiovascular (CV) risk factors, stroke, coronary artery disease (CAD), osteoporosis, diabetes mellitus (DM), chronic obstructive pulmonary disease (COPD), depression and neoplasms were compared between APS and RA patients using multivariate regression analysis. Results Ηyperlipidemia and obesity (ΒΜΙ ≥ 30 kg/m2) were comparable while hypertension, smoking, stroke and CAD were more prevalent in APS compared with RA patients. Osteoporosis and depression were more frequent in APS, while DM, COPD and neoplasms did not differ between the two groups. Comparison of APS subgroups to 1:2 matched RA patients revealed that smoking and stroke were more prevalent in both PAPS and SLE-APS vs RA. Hypertension, CAD and osteoporosis were more frequent only in SLE-APS vs RA, whereas DM was less prevalent in PAPS vs RA. Hyperlipidaemia was independently associated with CV events (combined stroke and CAD) in PAPS and SLE-APS, while CS duration was associated with osteoporosis in SLE-APS. Conclusion Comorbidity burden in APS (PAPS and SLE-APS) is comparable or higher than that in RA, entailing a high level of diligence for CV risk prevention, awareness for depression and CS exposure minimization.

To describe the profile of Enthesitis Related Arthritis’ (ERA) patients, in the era of biologic DMARDs (bDMARDs). This retrospective cohort study included patients with ERA monitored on a 3-month schedule for at least 1 year. Their metric assessment included the disease status and damage by applying the contemporary tools clinical-Juvenile Arthritis Disease Activity Score (c-JADAS), Juvenile Spondyloarthritis Disease Activity Index (JSpADA), clinical remission (CR) on/off medication and Juvenile Arthritis Damage Index (JADI). 43 patients (males 26) were enrolled, with a mean disease onset of 10.75 years. Median lag time from diagnosis to bDMARDs was 8.5 months. Patients with sacroiliitis received earlier bDMARDs (hazard ratio, HR 3.26). 36/43 patients achieved CR on medication (median time 11 months), which was correlated with compliance (HR: 3.62). The percentage of CR in patients with or without sacroiliitis was 35% and 63% respectively (p = 0.02). Twenty patients (47%) experienced a flare following CR (75%). The median flare-free survival following CR on/off medication was 42 and 34 months, respectively. At the last evaluation, both median baseline cJADAS and JSpADA dropped to 0, 13/43 patients had a persistent disease activity, while 17/43 and 13/43 patients were in CR on/off medication, respectively. The median patient percentage of CR was 54% and no patient had a JADI > 0. Increased lag time to bDMARDs was associated with increased CR (Odds ratio: 1.48). Early administration of bDMARDs and compliance improved long-term outcome of ERA. Sacroiliitis was a negative prognostic factor with an increased need for bDMARDs and diminished rates of CR.

Objective Endothelial dysfunction has been associated with increased cardiovascular events and overall mortality. Microvascular damage is prevalent both in diabetes mellitus (DM) and chronic kidney disease (CKD). Our aim was to compare microcirculatory function parameters in diabetic and non-diabetic CKD patients via nailfold video-capillaroscopy. Methods We included 48 diabetic and 48 non-diabetic adult CKD patients. All participants underwent nailfold video-capillaroscopy, during which capillary density was measured at normal conditions (baseline), after a 4-minute arterial occlusion (postocclusive reactive hyperemia), and at the end of a 2-minute venous occlusion (congestion phase). Results Diabetic patients presented significantly lower capillary density during reactive hyperemia (36.3 ± 3.8 vs 38.3 ± 4.3 capillaries/mm2 , P = .022) and at venous congestion (37.8 ± 4.0 vs 39.8 ± 4.2 capillaries/mm2 , P = .015). When stratified according to CKD stages, only in stage 3b capillary density was significantly lower in diabetic compared to non-diabetic subjects at baseline, during postocclusive hyperemia (36.8 ± 2.7 vs 40.0 ± 4.3 capillaries/mm2 , P = .037) and venous congestion (38.3 ± 2.8 vs 41.5 ± 3.5 capillaries/mm2 , P = .022). Conclusions Capillary density during postocclusive hyperemia and after venous congestion is lower in diabetic compared to non-diabetic CKD patients, a finding indicative that diabetes is an additional factor contributing to microcirculatory structural and functional impairment in CKD. These differences are more prominent in CKD stage 3b.

Inflammasomes are large intracellular complexes that induce inflammation in response to exogenous and endogenous damage signals. They regulate production and release of the proinflammatory cytokines IL-1β and IL-18, playing a defensive role against infections. Inflammasomes have also been involved in the pathogenesis of a wide range of autoinflammatory conditions that are caused by dysregulation of the IL-1 pathway, such as cryopyrinopathies and hereditary periodic fever syndromes. On top of that, research in recent years suggests that defects in inflammasome regulation and signaling associate with a number of autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis and others. In this review, we describe the inflammasome and mechanisms that trigger it, provide a brief review of autoinflammatory disorders and discuss the current understanding and emerging data from experimental and clinical studies for the role of the innate immune system and inflammasomes in the biology and pathogenesis of systemic autoimmune diseases.

Aim of the study To evaluate the current disease characteristics, treatment and comorbidities of rheumatoid arthritis (RA) in Greece. Methods Multicenter, cross-sectional study with a 9-month recruitment period between 2015 and 2016. Demographics, disease characteristics, treatment and comorbidities were collected via a web-based platform. Results 2.491 RA patients were recruited: 96% from tertiary referral centers, 79% were females with a mean age of 63.1 years and disease duration of 9.9 years. Fifty-two percent were rheumatoid factor and/or anti-CCP positive, while 41% had erosive disease. Regarding treatment, 82% were on conventional synthetic disease modifying anti-rheumatic drugs (csDMARDs), 42% on biologic DMARDs (TNFi: 22%, non-TNFi: 20%) and 40% on corticosteroids (mean daily dose: 5.2 mg). Despite therapy, 36% of patients had moderate and 12% high disease activity. The most frequent comorbidities were hypertension (42%), hyperlipidemia (33%), osteoporosis (29%), diabetes mellitus (15%) and depression (12%). Latent tuberculosis infection (positive tuberculin skin test or interferon gamma release assay) was diagnosed in 13 and 15.3% of patients, respectively. Regarding chronic viral infections, 6.2% had history of herpes zoster while 2% and 0.7% had chronic hepatitis B and C virus infection, respectively. A history of serious infection was documented in 9.6%. Only 36% and 52% of the participants had ever been vaccinated against pneumococcus and influenza virus, respectively. Conclusion This is one of the largest epidemiologic studies providing valuable data regarding the current RA characteristics in Greece. Half of patients were seropositive but despite therapy, half displayed residual disease activity, while preventive vaccination was limited.

Juvenile idiopathic arthritis (JIA) is an autoimmune disease that is characterized by persistent chronic arthritis and affected by genetic and environmental factors. Different genetic variations have been reported as risk factors for JIA. However, given that many results could not be replicated in individuals of different ancestral origin, it was assumed that heterogeneous genetic factors are involved in this disease. In the present study, we analyzed three single nucleotide polymorphisms (SNPs), namely PTPRC (rs10919563), TYK2 (rs34536443) and PRKCQ (rs4750316), which were found to be associated with JIA in previous studies. We also investigated whether the intron-4 located 27-bp VNTR of endothelial nitric oxide synthase (eNOS), is associated with risk for JIA in Greece. In total, 125 JIA patients and 221 healthy controls from northern Greece were included in the study as a sample set. Samples were then analyzed, and genotyped for the three SNPs with TaqMan primer-probe sets, using a Real-Time PCR platform (ViiA™ 7 Real-Time PCR system), while eNOS VNTR polymorphism was genotyped by PCR. Statistical analysis was performed using a GraphPad Prism statistical program. The χ2 test was used to examine differences of genotype and allele frequencies between patients and controls. Statistical significance was defined by using the two-tailed P

Objectives To describe the disease characteristics, continuous course and long-term outcome and to evaluate predictors of outcome in JIA in Greece. Methods We performed a retrospective cohort analysis of 17 years' prospective data on JIA. Outcome assessment included radiographic (modified Sharp-van der Heidje score), articular and extra-articular damage (Juvenile Arthritis Damage Index), functional ability (HAQ Disability Index), and the cumulative percentage time spent in a state of active disease and also in clinical remission off medication (CR) (according to Wallace's criteria). Results One hundred and two (72 females) patients under regular follow-up were enrolled. The disease age of onset [mean (SD)] was 7.7 (4) years, the interval from onset to last visit was 17.2 (6.7) years and the patients' current age was 25 (5.9) years. At the last follow-up visit, 53 patients (52%) had disease activity, while 23.5% were in CR. The cumulative percentage time spent in a state of active disease and CR over the disease course was 52.6 and 17.8%, respectively. Polyarticular subtype of onset and longer disease activity during the first 5 years were independent predictors of worse outcome. Additional telephone-based interviews of 205 former JIA patients who had been lost to follow-up as adults were performed to extend the interpretation of our findings to a broader JIA population. Almost half (47.6%) of the total cohort of 307 patients were found to be in CR at the final evaluation and 69.7% had no disability. Conclusion The available data indicate that JIA as a whole is a heterogeneous disease with significant variability in course and long-term outcome.

Background Our previous publication on Juvenile Idiopathic Arthritis (JIA) revealed that half of the pts had flares in adulthood, despite previous administration of several anti-TNFs. Objectives a. To describe the long-term outcome of adults with JIA or non-infectious uveitis (NIU), exposed to Adalimumab (ADA) as the single or last biologic during the transition period. b. To evaluate our model of transition in a subgroup of refractory to conventional DMARDs JIA or NIU pts, in the 1st Greek Transition Clinic for Pediatric Rheumatic Diseases. Methods Retrospective cohort analysis of Greek adults with JIA or NIU between 2004 and 2018. The JIA activity state was assessed by 2 quantitative tools: the Juvenile Arthritis Disease Activity Score-10 (JADAS-10, Clinical Remission [CR], Low, Moderate and High Disease Activity [LDA, MDA, HDA], respectively) and Wallace criteria (CR on/off ADA). Baseline was defined as the 1st ADA dose Results 28 pts were enrolled: 24 JIA pts (female 18), aged 20.6±3.1 yrs, for a f/u of 6.5±3 years (Group-A) and 4 female pts with active uveitis (2 with JIA-associated and 2 with NIU, mean aged: 18.9 yrs, f/u: 2.3 yrs) (Group-B). The age at baseline was 14.1±3.2 yrs in Group-A and 16.7 yrs in Group-B. The lag time from JIA onset to baseline was 6.3±3.8 yrs and the JIA subtypes were: 37.5% polyarthritis RF neg, 33.3% extended oligoarthritis, 20.8% enthesitis-related arthritis, 4.2% persistent oligoarthritis, 4.2% psoriatic arthritis. 11/24 (45.8%) pts (Group-A) and 3/4 pts (Group-B) were ANA positive, 5/24 JIA-pts had a history of uveitis (20.8%). Naive to anti-TNF drugs were 18 pts (75%) of Group-A and 4/4 from Group-B. The baseline JADAS-10 was 13.9±5.9. The ADA yr-administration was 5.3±2.3 in Group-A and 2 in Group-B. Compliance to ADA had 17/24 (70.8%) pts in Group-A and all from Group-B. Regarding safety, 4/28 patients (14.3%) experienced Events of Special Interest (1/33.6 patient-years), herpes zoster (n=1), anorexia nervosa (n=1), breast fibroadenoma (n=1) and uveitis (n=1). Among the Group-A pts: 4/24 (16.7%) discontinued ADA due to inefficacy and 1/24 due to pregnancy planning. 6/24 pts (25%) achieved CR and discontinued ADA after 5.3±1.6 yrs. CR off ADA lasted 15.5±9.8 mo. The rest 13/24 continued ADA at the last f/u. In Group-B, 3/4 were still on ADA and 1 pt discontinued ADA due to NIU remission after 4.2 yrs and sustained CR 16 mo off ADA. The median% of CR remission on ADA total administration period was 75% in Group-A and 100% in Group-B. Among the ongoing receivers: a) the JIA activity state at the last assessment was: CR 84.6%, LDA 7.7% MDA 7.7% (median JADAS: 0, Group-A), b) 100% were in remission in Group-B. Conclusion 86% of adult pts with JIA or NIU tolerate ADA well. Pts exposed to ADA achieved CR on/off medication in 75% and 25%, respectively. References [1] Dimopoulou D, et al.

Background Identification of the risk factors for the development of serious infections in patients with rheumatoid arthritis (RA) is critical for designing preventive measures and early treatment. Objectives To identify risk factors for serious infections and to validate the RABBIT risk score in RA patients in daily clinical practice. Methods Multicenter, prospective study of RA patients in Greece. Demographics, disease characteristics, treatments and co-morbidities were prospectively collected via a web-based platform at baseline and one year later. The observed incidence of serious infections was compared to the one estimated by the RABBIT score. Results 1.549 RA patients were included (women: 78%, mean age: 63 years, mean disease duration: 10.4 years, RF and/or anti-CCP positive: 54%, mean DAS28: 3.4, mean HAQ: 0.5, bDMARD use: 46%, corticosteroid use: 36%). During follow-up, 38 serious infections were recorded (incidence: 2.3/100 patient-years). Patients who developed a serious infection had longer disease duration (14.2 vs. 10.3 years, p=0.02), higher HAQ at baseline (0.85 vs. 0.5, p=0.006), a history of previous serious infection (26% vs. 10%, p=0.002) and were more likely to have chronic lung disease (23% vs. 9%, p=0.008) or cardiovascular disease (23% vs. 11%, p=0.04). Disease duration (OR: 1.04, CI: 1.01-1.08, p=0.025), history of previous infection (OR: 3.3, CI: 1.3-8.1, p=0.01) and chronic lung disease (OR: 3.03, CI: 1.17-7.85, p=0.023) remained statistical significant in multivariate logistic regression analysis. bDMARD use was not associated with increased risk in uni-or multi-variate analysis. Data for RABBIT score calculation were available in 1.349 patients. Estimated incidence per 100 patient-years was divided in Q1-Q4 quartiles (25-50-75th percentiles: 0.94-1.35-2.15). Estimated and observed incidence rates were in Q1: 0.8 and 0.54, Q2: 1.14 and 0.79, Q3: 1.76 and 1.84 and Q4: 3.7 and 5.6, respectively (Hosmer Lemeshaw test, p=0.9). Conclusion In this large, real life, prospective study of RA patients, the incidence of serious infections was 2.3/100 patient-years. Longer disease duration, history of previous serious infections and chronic lung disease were independently associated with the development of serious infections. RABBIT score predicted rather accurately the risk for serious infections in our cohort. References [1] Zink et al, Ann Rheum Dis. 2014 Sep; 73(9): 1673–1676.

Background: Giant cell arteritis (GCA) usually requires long-term therapy with corticosteroids and/or Disease Modifying Anti-rheumatic Drugs (DMARDs) but the exact factors that are associated with drug discontinuation in these patients have not been well defined. Objectives: To evaluate the baseline or on-treatment factors that influence drug survival in GCA. Methods: Data were derived from an ongoing, multicenter, prospective cohort study of patients with GCA. During the 1st phase of the study, data regarding demographic and clinical characteristics at baseline, type of treatment, adverse events of therapy and co-morbidities were retrospectively collected and analyzed. Predictors of drug discontinuation were examined by univariate and multivariate logistic regression analyses. Results: One hundred and seventy seven patients were included in the study; 70% (n=120) were women with a mean age at diagnosis of 74 ± 8.4 years. Diagnosis was established by temporal artery biopsy in 127 patients (72%), ultrasound of temporal arteries in 37 patients (21%) and large vessel imaging in 10 patients (6%). At diagnosis, the median ESR and CPR were 103 mm/h and 63 mg/L, respectively. All patients were treated initially with pos corticosteroids (median daily starting dose: 41 mg), while 12 (7%) of patients received pulse steroids. At the 1st patient evaluation (median follow-up from diagnosis: 3 years), the median daily steroid dose was 5 mg, while in 34% (n= 62) and 8% (n= 14) of patients a synthetic or biologic DMARD had been added, respectively. During that period, 24% (n=43) of patients had discontinued corticosteroids and 18% (n=32) all treatments. By univariate analysis, DMARD use was associated with a higher possibility for corticosteroid discontinuation (OR=2.3, p=0.017) but by multivariate logistic regression analysis only female sex (OR=0.49, p=0.07) and age at diagnosis (OR=0.94, p=0.01) were associated with a decreased risk for corticosteroid discontinuation. Similar results were found for discontinuation of all drugs [female sex (OR=0.4, p=0.05) and age at diagnosis (OR=0.9, p=0.046)]. Conclusion: In this large GCA cohort, only one out of four patients managed to discontinue corticosteroids and 20% all treatments ∼3 years after diagnosis. Multivariate analysis revealed only female sex and age at diagnosis as independent factors for treatment discontinuation.

Systemic sclerosis (SSc) is a chronic, systemic disease characterized by fibrosis of the skin and internal organs, vasculopathy, and auto-immune activation. On the top of severe organ involvement such as interstitial lung and myocardial fibrosis, pulmonary hypertension, and renal crisis, individuals diagnosed with SSc may suffer from a number of comorbidities. This is a narrative review according to published recommendations and we searched the online databases MEDLINE and EMBASE using as key words the following terms: systemic sclerosis, scleroderma, myocardial fibrosis in combination with micro- and macro-vascular disease, cardiac involvement, atherosclerosis, cardiovascular disease and coronary arteries, infections, cancer, depression, osteoporosis, and dyslipidemia. Although data are usually inconclusive it appears that comorbidities with significant impact on life expectancy, namely cardiovascular disease, infections, and cancer as well as phycological disorders affecting emotional and mental health are highly prevalent in SSc population. Thereafter, the aim of this review is to summarize the occurrence and the clinical significance of such comorbidities in SSc population and to discuss how rheumatologists can incorporate the management of these conditions in daily clinical practice.

Spondyloarthropathies (SpA) include many different forms of inflammatory arthritis and can affect the spine (axial SpA) and/or peripheral joints (peripheral SpA) with Ankylosing spondylitis (AS) being the prototype of the former. Extra-articular manifestations, like uveitis, psoriasis and inflammatory bowel disease (IBD) are frequently observed in the setting of SpA and are, in fact, part of the SpA classification criteria. Bowel involvement seems to be the most common of these manifestations. Clinically evident IBD is observed in 6%-14% of AS patients, which is significantly more frequent compared to the general population. Besides, it seems that silent microscopic gut inflammation, is evident in around 60% in AS patients. Interestingly, occurrence of IBD has been associated with AS disease activity. For peripheral SpA, two different forms have been proposed with diverse characteristics. Of note, SpA (axial or peripheral) is more commonly observed in Crohn's disease than in ulcerative colitis. The common pathogenetic mechanisms that explain the link between IBD and SpA are still ill-defined. The role of dysregulated microbiome along with migration of T lymphocytes and other cells from gut to the joint ("gut-joint" axis) has been recognized, in the context of a genetic background including associations with alleles inside or outside the human leukocyte antigen system. Various therapeutic modalities are available with monoclonal antibodies against tumour necrosis factor, interleukin-23 and interleukin-17, being the most effective. Both gastroenterologists and rheumatologists should be alert to identify the co-existence of these conditions and ideally follow-up these patients in combined clinics.
