Abstract
BACKGROUND we aimed to estimate the prevalence of Amino acyl-transfer ribonucleic acid synthetase antibodies (Anti-ARS); myositis specific antibodies, among patients with systemic sclerosis (SSc), to evaluate the clinical associations of anti-ARS antibodies in SSc patients and to identify risk factors for development of interstitial lung disease (ILD) in SSc. METHODS A prospective study of 71 systemic sclerosis patients in our rheumatology clinic in Israel. Sera were tested for myositis antibodies. Data on patients clinical and serological manifestations and treatment were collected and compared according to anti-ARS antibodies and ILD. RESULTS Prevalence of anti-ARS antibodies was 6% (4/71) with anti PL-7, anti- OJ and Jo-1 positivity. Anti Ro-52 was found in 27%, anti-PM/Scl 75, anti-PM/Scl 100 and anti-SRP in 6%, anti-Ku in 3%, anti-Mi-2 beta and anti-Mi-2 alfa in 4%, anti- NXP2 and anti-TIF1gamma in 1%. ILD complication was observed in 42% of patients and was associated with anti RNAP-III, anti Scl-70 and Anti-ARS antibodies. In multiple logistic regression, anti Scl-70 was associated with 6-fold higher risk for ILD. CONCLUSION Anti-ARS antibodies were observed in 6% of SSc patients. All of them had ILD. Due to the low prevalence of anti-ARS, this study could not describe clinical associations of anti-ARS antibodies in SSc patients.

Abstract
OBJECTIVES Gastroesophageal reflux disease (GERD) occurs frequently in patients with SSc. We investigated whether the presence of GERD and/or the use of anti-acid therapy, specifically proton-pump inhibitors (PPIs), are associated with long-term outcomes, especially in SSc-associated interstitial lung disease (SSc-ILD). METHODS We retrospectively analysed patients with SSc and SSc-ILD from the German Network for Systemic Sclerosis (DNSS) database (2003 onwards). Kaplan-Meier analysis compared overall survival (OS) and progression-free survival (PFS) in patients with GERD vs without GERD (SSc and SSc-ILD), and PPI vs no PPI use (SSc-ILD only). Progression was defined as a decrease in either percentage predicted forced vital capacity of ≥10% or single-breath diffusing capacity for carbon monoxide of ≥15%, or death. RESULTS It was found that 2693/4306 (63%) registered patients with SSc and 1204/1931 (62%) with SSc-ILD had GERD. GERD was not associated with decreased OS or decreased PFS in patients in either cohort. In SSc-ILD, PPI use was associated with improved OS vs no PPI use after 1 year [98.4% (95% CI: 97.6, 99.3); n = 760 vs 90.8% (87.9-93.8); n = 290] and after 5 years [91.4% (89.2-93.8); n = 357 vs 70.9% (65.2-77.1); n = 106; P < 0.0001]. PPI use was also associated with improved PFS vs no PPI use after 1 year [95.9% (94.6-97.3); n = 745 vs 86.4% (82.9-90.1); n = 278] and after 5 years [66.8% (63.0-70.8); n = 286 vs 45.9% (39.6-53.2); n = 69; P < 0.0001]. CONCLUSION GERD had no effect on survival in SSc or SSc-ILD. PPIs improved survival in patients with SSc-ILD. Controlled, prospective trials are needed to confirm this finding.

Abstract
Systemic sclerosis (SSc) is a rare autoimmune connective tissue disease with multi-organ involvement, fibrosis and vasculopathy. Treatment in SSc, including early diffuse cutaneous SSc (dcSSc) and the use of organ-specific therapies, has improved, as evident from randomized clinical trials. Treatments for early dcSSc include immunosuppressive agents such as mycophenolate mofetil, methotrexate, cyclophosphamide, rituximab and tocilizumab. Patients with rapidly progressive early dcSSc might be eligible for autologous haematopoietic stem cell transplantation, which can improve survival. Morbidity from interstitial lung disease and pulmonary arterial hypertension is improving with the use of proven therapies. Mycophenolate mofetil has surpassed cyclophosphamide as the initial treatment for SSc-interstitial lung disease. Nintedanib and possibly perfinidone can be considered in SSc pulmonary fibrosis. Pulmonary arterial hypertension is frequently treated with initial combination therapy (for example, with phosphodiesterase 5 inhibitors and endothelin receptor antagonists) and, if necessary, the addition of a prostacyclin analogue. Raynaud phenomenon and digital ulcers are treated with dihydropyridine calcium channel blockers (especially nifedipine), then phosphodiesterase 5 inhibitors or intravenous iloprost. Bosentan can reduce the development of new digital ulcers. Trial data for other manifestations are mostly lacking. Research is needed to develop targeted and highly effective treatments, best practices for organ-specific screening and early intervention, and sensitive outcome measurements.

Abstract
Pulmonary involvement complicates the various aspects of care in patients suffering from autoimmune disorders. The epidemiological data generated over the last 10 to 15 years have improved the overall understanding of the risk factors and pathophysiological mechanisms involved in pulmonary involvement in rheumatological conditions. Recent advances in genetics have provided superior insight into the pathogenesis of autoimmune diseases and the underlying pulmonary involvement. This review article provides a concise overview of the four most common rheumatological conditions associated with pulmonary involvement: systemic lupus erythematosus (SLE), dermatomyositis/polymyositis, rheumatoid arthritis (RA), and systemic sclerosis (SSc). The clinical, epidemiological, and genetic aspects of these diseases are summarized in this article with particular emphasis on the characteristic patterns of pulmonary involvement in radiological imaging and various treatment options for each of these autoimmune diseases and their lung manifestations.

Abstract
OBJECTIVE To evaluate extent of interstitial lung disease (ILD) and oesophageal involvement using high-resolution computed tomography (HRCT) in early diffuse SSc patients after autologous haematopoietic stem cell transplantation (aHSCT). METHODS Overall chest HRCT, lung function and skin score changes were evaluated in 33 consecutive diffuse SSc patients before and after aHSCT during yearly routine follow-up visits between January 2000 and September 2016. Two independent radiologists blindly assessed the ILD extent using semi-quantitative Goh and Wells method, the widest oesophageal diameter (WOD) and the oesophageal volume (OV) on HRCT. Patients were retrospectively classified as radiological responders or non-responders, based on achieved stability or a decrease of 5% or more of HRCT-ILD at 24 months post-aHSCT. RESULTS Using a linear mixed model, the regressions of the extent of ILD and of ground glass opacities were significant at 12 months (ILD P = 0.001; ground glass opacities P = 0.0001) and at 24 months (ILD P = 0.007; ground glass opacities P = 0.0008) after aHSCT, with 18 patients classified as radiological responders (probability of response 0.78 [95% CI 0.58, 0.90]). Meanwhile the WOD and the OV increased significantly at 12 months (WOD P = 0.03; OV P = 0.34) and at 24 months (WOD P = 0.002; OV P = 0.007). Kaplan-Meier analyses showed a trend towards better 5-year survival rates (100% vs 60%; hazard ratio 0.23 [95% CI 0.03, 1.62], P = 0.11) among radiological responders vs non-responders at 24 month follow-up after aHSCT. CONCLUSION Real-world data analysis confirmed significant improvement in extent of HRCT SSc-ILD 24 months after aHSCT, although oesophageal dilatation worsened requiring specific attention.

Abstract
AIM Interstitial lung disease (ILD) is the leading cause of disease-related death in systemic sclerosis (SSc). Here, we assess baseline characteristics of SSc subjects with and without restrictive lung disease (RLD) in a multi-center, US-based registry. METHODS SSc patients within 5 years of disease onset were enrolled in the Collaborative National Quality and Efficacy Registry (CONQUER), a multi-center US-based registry of SSc study participants (age ≥ 18 years) enrolled at 13 expert centers. All subjects met 2013 American College of Rheumatology / European League Against Rheumatism criteria. Subjects with a pulmonary function test (PFT) at baseline before April 1, 2020 were included. High-resolution computed tomography scan of the chest was not available to characterize ILD for all subjects. RLD was defined as forced vital capacity (FVC) <80% or total lung capacity (TLC) <80% predicted. RESULTS There were 160 (45%) SSc subjects characterized as having RLD. There was no significant difference in age, gender or disease duration. RLD subjects had a mean disease duration from date of first non-Raynaud's symptom of 2.6 years and a mean FVC% predicted of 67% at baseline. In multivariable analysis, non-White race, higher physician global health assessment and modified Medical Research Council (mMRC) dyspnea scores, were independently associated with RLD. In the subgroup of RLD subjects with ILD, ILD had a negative correlation with RNA polymerase III antibody. CONCLUSION CONQUER is the largest, multi-center, prospective cohort of early SSc patients in the US. Non-White race was independently associated with RLD. In addition, 45% of CONQUER subjects already had RLD, highlighting the importance of screening for SSc-ILD at initial diagnosis.

Abstract
Patients with systemic sclerosis are at high risk of developing systemic sclerosis–associated interstitial lung disease. Symptoms and outcomes of systemic sclerosis–associated interstitial lung disease range from subclinical lung involvement to respiratory failure and death. Early and accurate diagnosis of systemic sclerosis–associated interstitial lung disease is therefore important to enable appropriate intervention. The most sensitive and specific way to diagnose systemic sclerosis–associated interstitial lung disease is by high-resolution computed tomography, and experts recommend that high-resolution computed tomography should be performed in all patients with systemic sclerosis at the time of initial diagnosis. In addition to being an important screening and diagnostic tool, high-resolution computed tomography can be used to evaluate disease extent in systemic sclerosis–associated interstitial lung disease and may be helpful in assessing prognosis in some patients. Currently, there is no consensus with regards to frequency and scanning intervals in patients at risk of interstitial lung disease development and/or progression. However, expert guidance does suggest that frequency of screening using high-resolution computed tomography should be guided by risk of developing interstitial lung disease. Most experienced clinicians would not repeat high-resolution computed tomography more than once a year or every other year for the first few years unless symptoms arose. Several computed tomography techniques have been developed in recent years that are suitable for regular monitoring, including low-radiation protocols, which, together with other technologies, such as lung ultrasound and magnetic resonance imaging, may further assist in the evaluation and monitoring of patients with systemic sclerosis–associated interstitial lung disease.

Abstract
Background Radiomic features calculated from routine medical images show great potential for personalised medicine in cancer. Patients with systemic sclerosis (SSc), a rare, multiorgan autoimmune disorder, have a similarly poor prognosis due to interstitial lung disease (ILD). Here, our objectives were to explore computed tomography (CT)-based high-dimensional image analysis (“radiomics”) for disease characterisation, risk stratification and relaying information on lung pathophysiology in SSc-ILD. Methods We investigated two independent, prospectively followed SSc-ILD cohorts (Zurich, derivation cohort, n=90; Oslo, validation cohort, n=66). For every subject, we defined 1355 robust radiomic features from standard-of-care CT images. We performed unsupervised clustering to identify and characterise imaging-based patient clusters. A clinically applicable prognostic quantitative radiomic risk score (qRISSc) for progression-free survival (PFS) was derived from radiomic profiles using supervised analysis. The biological basis of qRISSc was assessed in a cross-species approach by correlation with lung proteomic, histological and gene expression data derived from mice with bleomycin-induced lung fibrosis. Results Radiomic profiling identified two clinically and prognostically distinct SSc-ILD patient clusters. To evaluate the clinical applicability, we derived and externally validated a binary, quantitative radiomic risk score (qRISSc) composed of 26 features that accurately predicted PFS and significantly improved upon clinical risk stratification parameters in multivariable Cox regression analyses in the pooled cohorts. A high qRISSc score, which identifies patients at risk for progression, was reverse translatable from human to experimental ILD and correlated with fibrotic pathway activation. Conclusions Radiomics-based risk stratification using routine CT images provides complementary phenotypic, clinical and prognostic information significantly impacting clinical decision making in SSc-ILD. CT-based radiomics decodes phenotypic, prognostic and molecular differences in SSc-ILD, and predicts progression-free survival with a significant impact on future clinical decision making in SSc-ILDhttps://bit.ly/3zPaMOn

Abstract
OBJECTIVES Although interstitial lung disease (ILD) occurs in over half of systemic sclerosis (SSc) patients and represents a leading cause of mortality, there are currently no preventative strategies. We evaluated if gastroprotective agents were associated with a lower incident risk of SSc-ILD. METHODS An SSc cohort without clinically apparent ILD at baseline was constructed from the Canadian Scleroderma Research Group registry. The primary exposure was any use of gastroprotective agents. Treatment with promotility agents was assessed as a secondary exposure. Time to development of clinically apparent ILD was compared between exposed and unexposed person-time, using a multivariable marginal structural Cox model incorporating inverse probability of treatment weights to address time-varying confounding. RESULTS In total, 798 subjects met inclusion criteria. At cohort entry, median disease duration was 7.6 (IQR 3.9-15.6) years. During a median 4.4 (IQR 2.6-7.2) years of follow-up, 158 new ILD cases were diagnosed, for a crude incidence of 4.4 (95% CI 3.8-5.1) events per 100 person-years. Most (2085, 73.4%) person-visits were exposed to gastroprotective agents, 579 (20.4%) were exposed to promotility agents, and 554 (19.5%) were exposed to both agents. The marginal structural weighted hazard ratio (HR) for incident ILD related to gastroprotective agents was 0.86 (95% CI 0.52-1.41). When exposure was defined as treatment with promotility agents, the weighted adjusted HR was 0.79 (95% CI: 0.35-1.77). CONCLUSION In this large retrospective cohort study, we were unable to demonstrate a protective role for gastroprotective and promotility agents in preventing clinically apparent SSc-ILD.

Abstract
OBJECTIVES To identify overall disease course, progression patterns and risk factors predictive for progressive interstitial lung disease (ILD) in patients with systemic sclerosis-associated ILD (SSc-ILD), using data from the European Scleroderma Trials And Research (EUSTAR) database over long-term follow-up. METHODS Eligible patients with SSc-ILD were registered in the EUSTAR database and had measurements of forced vital capacity (FVC) at baseline and after 12±3 months. Long-term progressive ILD and progression patterns were assessed in patients with multiple FVC measurements. Potential predictors of ILD progression were analysed using multivariable mixed-effect models. RESULTS 826 patients with SSc-ILD were included. Over 12±3 months, 219 (27%) showed progressive ILD: either moderate (FVC decline 5% to 10%) or significant (FVC decline >10%). A total of 535 (65%) patients had multiple FVC measurements available over mean 5-year follow-up. In each 12-month period, 23% to 27% of SSc-ILD patients showed progressive ILD, but only a minority of patients showed progression in consecutive periods. Most patients with progressive ILD (58%) had a pattern of slow lung function decline, with more periods of stability/improvement than decline, whereas only 8% showed rapid, continuously declining FVC; 178 (33%) experienced no episode of FVC decline. The strongest predictive factors for FVC decline over 5 years were male sex, higher modified Rodnan skin score and reflux/dysphagia symptoms. CONCLUSION SSc-ILD shows a heterogeneous and variable disease course, and thus monitoring all patients closely is important. Novel treatment concepts, with treatment initiation before FVC decline occurs, should aim for prevention of progression to avoid irreversible organ damage.

Abstract
Systemic sclerosis is an autoimmune connective tissue disease, which is characterised by immune dysregulation and progressive fibrosis that typically affects the skin, with variable internal organ involvement. It is a rare condition that affects mostly young and middle-aged women, resulting in disproportionate morbidity and mortality. Currently, interstitial lung disease is the most common cause of death among patients with systemic sclerosis, with a prevalence of up to 30% and a 10-year mortality of up to 40%. Interstitial lung disease is more common among African Americans and in people with the diffuse cutaneous form of systemic sclerosis or anti-topoisomerase 1 antibodies. Systemic sclerosis-associated interstitial lung disease most commonly presents with dyspnoea, cough, and a non-specific interstitial pneumonia pattern on CT scan, with a minority of cases fulfilling the criteria for usual interstitial pneumonia. The standard therapy has traditionally been combinations of immunosuppressants, particularly mycophenolate mofetil or cyclophosphamide. These immunosuppressants can be supplemented by targeted biological and antifibrotic therapies, whereas autologous haematopoietic stem-cell transplantation and lung transplantation are reserved for refractory cases.

Abstract
Introduction: Various anatomical defects predispose patients with congenital diaphragmatic hernia (CDH) to develop gastroesophageal reflux disease (GERD). The fetal endoscopic tracheal occlusion (FETO) has increased the survival of patients with severe CDHs. The aim of this study was to study GERD in patients who underwent FETO. Materials and Methods: We included patients with CDH treated with or without FETO ("FETO" and "no-FETO" group, respectively) from 2013 to 2016. Data on gestational age (GA), birth weight (BW), initial observed/expected lung to head ratio (O/E LHR), final O/E LHR, duration of ventilation and hospitalization, maximal tracheal diameter, and pulmonary volume were collected. All patients underwent pH-metry after 1 year of life, and the results were compared between groups and correlated to risk factors. Results: Thirty-two patients were included in the study: 10 FETO and 22 no-FETO. No significant differences were observed in the pH-metric results of the two groups. No correlation was found between GA, BW, initial O/E LHR, maximal tracheal diameter, pulmonary volume, and pH-metric results. pH-metric results were correlated with the total duration of ventilation (R = 0.5, p = 0.003) and of hospitalization (R = 0.54, p = 0.001). Gastric herniation is associated with the worse pH-metric result. Conclusions: The FETO procedure does not seem to represent an independent risk factor for GERD. However, patients with the most severe CDH have the worst GERD.

Abstract
OBJECTIVE To examine the association of anti-RNPC-3 antibodies in patients with systemic sclerosis (scleroderma or SSc) with selected gastrointestinal (GI) tract complications. METHODS Sera from patients with SSc with or without severe GI dysfunction (total parenteral nutrition dependence) from the Johns Hopkins Scleroderma Center were screened for anti-RNPC-3 antibodies. We then examined anti-RNPC-3-positive cases and negative SSc controls from the University of Pittsburgh and the University of Pittsburgh Medical Center (UPMC) scleroderma cohort to confirm our findings and to examine whether specific GI features were associated with anti-RNPC-3 antibodies. RESULTS In the discovery cohort, patients with SSc with severe GI dysfunction (n = 37) and without GI dysfunction (n = 38) were screened for anti-RNPC-3 antibodies. The former were more likely to have anti-RNPC-3 antibodies (14% versus 3%; P = 0.11). In the Pittsburgh cohort, moderate-to-severe GI dysfunction (Medsger GI score ≥2) was present in 36% of anti-RNPC-3-positive patients versus 15% of anti-RNPC-3-negative patients (P ≤ 0.01). Anti-RNPC-3-positive patients were more likely to be male (31% versus 15%; P = 0.04), African American (18% versus 6%; P = 0.02), have esophageal dysmotility (93% versus 62%; P < 0.01), and interstitial lung disease (ILD) (77% versus 35%; P < 0.01). After adjusting for relevant covariates and potential confounders, moderate-to-severe GI disease was associated with anti-RNPC-3 antibodies (odds ratio [OR] 3.8 [95% confidence interval (95% CI) 1.0-14.3]), and ILD trended toward significance (OR 2.8 [95% CI 1.0-8.2]). CONCLUSION Patients with SSc and anti-RNPC-3 antibodies are more likely to be male and African American and to have moderate-to-severe GI disease and ILD. Further studies on larger patient cohorts may be helpful in further defining subsets of patients with SSc at risk for severe GI involvement.

Abstract
Connective tissue disease (CTD) is a collection of disorders characterized by various signs and symptoms such as circulation of autoantibodies in the entire system causing damage to internal organs. Interstitial lung disease (ILD) which is associated with CTD is referred to as CTD-ILD. Patients diagnosed with ILD should be thoroughly examined for the co-occurrence of CTD, since the treatment procedures and prognosis of CTD-ILD are vary from those of idiopathic interstitial pneumonia. The representative types of CTD which may accompany ILD include rheumatoid arthritis, systemic sclerosis (SSc), Sjögren's syndrome, mixed CTD, idiopathic inflammatory myopathies, and systemic lupus erythematous. Of these, ILD most frequently co-exists with SSc. If an ILD is observed in the chest, high resolution computed tomography and specific diagnostic criteria for any type of CTD are met, then a diagnosis of CTD-ILD is made. It is challenging to conduct a properly designed randomized study on CTD-ILD, due to low incidence. Therefore, CTD-ILD treatment approach is yet to been established in absence of randomized controlled clinical trials, with the exception of SSc-ILD. When a patient is presented with acute CTD-ILD or if symptoms occur due to progression of the disease, steroid and immunosuppressive therapy are generally considered.

Abstract
Interstitial lung disease (ILD) is the leading cause of morbidity and mortality in systemic sclerosis (SSc). We performed a systematic review to characterise the use and validation of pulmonary function tests (PFTs) as surrogate markers for systemic sclerosis-associated interstitial lung disease (SSc-ILD) progression.Five electronic databases were searched to identify all relevant studies. Included studies either used at least one PFT measure as a longitudinal outcome for SSc-ILD progression (i.e. outcome studies) and/or reported at least one classical measure of validity for the PFTs in SSc-ILD (i.e. validation studies).This systematic review included 169 outcome studies and 50 validation studies. Diffusing capacity of the lung for carbon monoxide (DLCO) was cumulatively the most commonly used outcome until 2010 when it was surpassed by forced vital capacity (FVC). FVC (% predicted) was the primary endpoint in 70.4% of studies, compared to 11.3% for % predicted DLCO Only five studies specifically aimed to validate the PFTs: two concluded that DLCO was the best measure of SSc-ILD extent, while the others did not favour any PFT. These studies also showed respectable validity measures for total lung capacity (TLC).Despite the current preference for FVC, available evidence suggests that DLCO and TLC should not yet be discounted as potential surrogate markers for SSc-ILD progression.

Abstract
Several effective drugs have been identified for the treatment of systemic sclerosis (SSc). However, in advanced cases, not only their effectiveness is reduced but they may be also harmful due to their side-effects. Therefore, early diagnosis and early treatment is most important for the treatment of SSc. We established diagnostic criteria for SSc in 2003 and early diagnostic criteria for SSc in 2011, for the purpose of developing evaluation of each organ in SSc. Moreover, in November 2013, the American College of Rheumatology and the European Rheumatology Association jointly developed new diagnostic criteria for increasing their sensitivity and specificity, so we revised our diagnostic criteria and severity classification of SSc. Furthermore, we have revised the clinical guideline based on the newest evidence. In particular, the clinical guideline was established by clinical questions based on evidence-based medicine according to the New Minds Clinical Practice Guideline Creation Manual (version 1.0). We aimed to make the guideline easy to use and reliable based on the newest evidence, and to present guidance as specific as possible for various clinical problems in treatment of SSc.

Abstract
Lung illness encountered in patients with rheumatic diseases bears clinical significance in terms of increased morbidity and mortality as well as potential challenges placed on patient care. Although our understanding of natural history of this important illness is still limited, epidemiologic knowledge has been accumulated during the past decade to provide useful information on the risk factors and prognosis of lung involvements in rheumatic diseases. Moreover, the pathogenesis particularly in the context of genetics has been greatly updated for both the underlying rheumatic disease and associated lung involvement. This review will focus on the current update on the epidemiologic and genetics features and treatment options of the lung involvements associated with four major rheumatic diseases (rheumatoid arthritis, systemic sclerosis, myositis, and systemic lupus erythematosus), with more attention to a specific form of involvement or interstitial lung disease.

Abstract
This study aims to investigate pre-clinical esophageal involvement in systemic sclerosis (SSc) by high-resolution impedance manometry (HRiM), its associations with disease features including lung involvement, and its predictivity of esophageal symptoms overtime. Charts of 45 asymptomatic (no heartburn/regurgitation/dysphagia) SSc patients (96% females; mean age 46 years) with at least one follow-up (FU) visit and complete clinical, serological, functional, and radiological assessment, including high-resolution computed tomography (HRCT) of the chest and lung function tests, that had undergone esophageal HRiM were retrospectively evaluated. Esophagogastric junction-contractile integral (EGJ-CI) and esophageal body motility, as evaluated by mean distal contractile integral (DCI), were assessed. SSc patients had a normal esophageal motility in 7/45 cases, a defective EGJ-CI in 28, an ineffective esophageal motility (IEM) in 17, and aperistalsis in 12. Defective EGJ-CI was associated with IEM/aperistalsis in 20 cases, while 9 patients had isolated IEM. Defective EGJ-CI and/or IEM/aperistalsis were associated with a diffusing lung capacity for CO < 80% of predicted value (all p < 0.05), while defective EGJ-CI was also associated with interstitial lung disease on HRCT (p = 0.03). Prevalence of any HRiM abnormality was higher in anti-centromere antibody negative patients (all p < 0.05). IEM/aperistalsis independently increased the risk of esophageal symptoms by 2.3-fold (95% CI 1.1-5.7) and was associated with their higher cumulative incidence with respect to patients with other HRiM patterns at FU (χ2 = 4.63; p = 0.03). SSc patients asymptomatic for esophageal involvement can have HRiM abnormalities in up to 84% of cases. A baseline-impaired motility is a risk factor for symptomatic esophageal disease.

Abstract
The objective of the study is to determine the importance of the mode of onset as prognostic factor in systemic sclerosis (SSc). Data were collected from the Spanish Scleroderma Registry (RESCLE), a nationwide retrospective multicenter database created in 2006. As first symptom, we included Raynaud's phenomenon (RP), cutaneous sclerosis, arthralgia/arthritis, puffy hands, interstitial lung disease (ILD), pulmonary arterial hypertension (PAH), and digestive hypomotility. A total of 1625 patients were recruited. One thousand three hundred forty-two patients (83%) presented with RP as first symptom and 283 patients (17%) did not. Survival from first symptom in those patients with RP mode of onset was higher at any time than those with onset as non-Raynaud's phenomenon: 97 vs. 90% at 5 years, 93 vs. 82% at 10 years, 83 vs. 62% at 20 years, and 71 vs. 50% at 30 years (p < 0.001). In multivariate analysis, factors related to mortality were older age at onset, male gender, dcSSc subset, ILD, PAH, scleroderma renal crisis (SRC), heart involvement, and the mode of onset with non-Raynaud's phenomenon, especially in the form of puffy hands or pulmonary involvement. The mode of onset should be considered an independent prognostic factor in systemic sclerosis and, in particular, patients who initially present with non-Raynaud's phenomenon may be considered of poor prognosis.

Abstract
BACKGROUND ESD allows higher rates of en-bloc and R0 resections, but has occasionally complications such as aspiration pneumonia. Factors associated with aspiration pneumonia are not completely understood. AIMS To analyze the relationship between aspiration pneumonia and preoperative factors including pulmonary function tests. METHODS A total of 978 patients with gastric tumors who had received pulmonary function tests were treated by ESD between June 2006 and May 2014. Pulmonary function tests were assessed using a spirometer. The patients were categorized into four groups according to the predicted vital capacity (%VC) and forced expiratory volume in 1 s as a percentage of forced vital capacity (FEV1.0%): normal; restrictive pulmonary dysfunction; obstructive; and mixed. The factors associated with aspiration pneumonia were retrospectively analyzed. RESULTS Among the 268 cases with abnormal pulmonary function, 10 cases (3.7%) developed aspiration pneumonia. On the other hand, 7 cases (1.0%) with normal pulmonary function developed pneumonia. There was a significant correlation between pulmonary function and aspiration pneumonia (p = 0.010). When the pulmonary function cases were stratified into subgroups, 2.5% of cases with obstructive pulmonary dysfunction developed pneumonia, 5.5% with restrictive and 5.3% with mixed. By logistic regression analysis, pulmonary function, the presence of cerebral vascular disease, and procedure time were identified as significant independent risk factors associated with aspiration pneumonia. The odds ratios for pulmonary function, cerebral vascular disease, and procedure time were 3.6, 5.1, and 5.2, respectively. CONCLUSIONS Preoperative pulmonary function tests may be useful markers to evaluate the risk for aspiration pneumonia after gastric ESD.

Abstract
Autoimmune connective tissue diseases (CTDs) have a propensity to affect multiple organ systems as well as physical function, quality of life, and survival. Their clinical heterogeneity, multisystem involvement, and low worldwide prevalence present challenges for researchers to establish a study design to help better understand the course and outcomes of CTDs. Systemic sclerosis (SSc) is a notable example of a CTD, wherein longitudinal cohort studies (LCS) have enabled us to elucidate disease manifestations, disease course, and risk and prognostic factors for clinically important outcomes, by embedding research in clinical practice. Nevertheless, further efforts are needed to better understand SSc especially with regard to recognizing organ involvement early, developing new therapies, optimizing the use of existing therapies, and defining treatment targets. The heterogeneous multi-organ nature of SSc would lend itself well to a structured model of care, wherein step-up treatment algorithms are used with the goal of attaining a prespecified treatment target. In this chapter, we discuss the rationale for a structured treatment approach in SSc and propose possible treatment algorithms for three of the more common disease manifestations, namely skin involvement, digital ulcers and gastrointestinal tract involvement. We discuss possible strategies for evaluating and implementing these algorithms in the setting of LCS. We conclude by presenting a research agenda for the development of structured models of care in SSc.

Abstract
There are few studies on predictors of inpatient mortality in patients with systemic sclerosis (SSc). Knowledge of these predictors is important for the early identification of patients at high risk of inpatient death and for the recognition of modifiable factors. The aim of this study was to define factors associated with greater inpatient mortality in SSc. All admissions coded for SSc (ICD-9-710.1) at the Hospital of University of Pennsylvania, between 2001 and 2011, were reviewed. The diagnosis of SSc was confirmed, and deaths were identified by chart review. For each death, an age, sex, and race matched control with SSc (who did not die during their hospitalization) was identified. We hypothesized group differences in SSc characteristics, non-SSc co-morbidities, and admission labs. Group differences were analyzed using Student's t test as well as Chi(2) tests for dichotomous variables. Exposures associated with death in univariate analyses were used to form a final parsimonious multivariable logistic regression model. After analysis of 658 SSc admissions, 29 cases and 29 matched controls were studied. A significant difference in non-SSc lung disease (p = 0.03), aspiration events (p < 0.01), blood urea nitrogen (BUN) (p < 0.01), and hemoglobin (p = 0.03) was noted between subjects that died compared to matched controls. Odds of death were higher in patients with a higher BUN (OR = 1.06, CI = 1.02-1.11), non-SSc lung disease (OR = 3.87, CI = 1.26-11.88), and aspiration events (OR = 30, CI = 3.58-250.80) and lower in patients with a higher hemoglobin (OR = 0.73, CI = 0.54-0.97). A high BUN, a history of aspiration events, and low Hgb were found to be independently associated with risk of death. A history of lung disease, anemia, renal dysfunction, and aspiration events is associated with higher in-hospital mortality in patients with SSc. The odds of dying in the hospital were 30 times higher among patients with an aspiration event. Stringent measures should be considered to prevent aspiration in at-risk patients.

Abstract
OBJECTIVE A patulous esophagus on high-resolution computed tomography (HRCT) of the thorax is frequently observed in patients with systemic sclerosis (SSc). Microaspiration has been purported to play a role in the development and progression of SSc interstitial lung disease (ILD), but studies examining the role of microaspiration in SSc ILD have yielded conflicting results. This study was conducted to determine the association between esophageal diameter and SSc ILD. METHODS A cross-sectional study of Northwestern Scleroderma Registry patients with available HRCT exams was conducted. The predictor variable was the widest esophageal diameter (WED) on HRCT, and the primary and secondary outcome variables were radiographic ILD and pulmonary function tests respectively. The degree of radiographic ILD was assessed using a semi-quantitative score adapted from published methods. Estimated regression coefficients adjusted for age, sex, race, body mass index, smoking; SSc disease subtype, serum autoantibodies, and disease duration; modified Rodnan skin score, proton pump inhibitor, and immune suppressant medication use and erythrocyte sedimentation rate were calculated. RESULTS A total of 270 subjects were studied. In the adjusted analyses, there were positive associations between WED and total ILD score (β = 0.27; 95% CI: 0.09-0.41), fibrosis (β = 0.15; 95% CI: 0.07-0.23), and ground glass opacities (β = 0.12; 95% CI: 0.04-0.20); there were negative associations between WED and FVC % predicted (β = -0.42; 95% CI: -0.69 to -0.13), and adjusted DLCO % predicted (β = -0.45; 95% CI: -0.80 to -0.09) after adjusting for potential confounders. CONCLUSIONS Increasing esophageal diameter on HRCT in patients with SSc is associated with more severe radiographic ILD, lower lung volumes, and lower DLCO % predicted. Longitudinal studies are needed to determine if esophageal dilatation is associated with the incidence and/or progression of ILD in patients with SSc.

Abstract
The lung is a common site of complications of systemic connective tissue disease (CTD), and lung involvement can present in several ways. Interstitial lung disease (ILD) and pulmonary hypertension are the most common lung manifestations in CTD. Although it is generally thought that interstitial lung disease develops later on in CTD it is often the initial presentation ("lung dominant" CTD). ILD can be present in most types of CTD, including rheumatoid arthritis, scleroderma, systemic lupus erythematosus, polymyositis or dermatomyositis, Sjögren's syndrome, and mixed connective tissue disease. Despite similarities in clinical and pathologic presentation, the prognosis and treatment of CTD associated ILD (CTD-ILD) can differ greatly from that of other forms of ILD, such as idiopathic pulmonary fibrosis. Pulmonary hypertension (PH) can present as a primary vasculopathy in pulmonary arterial hypertension or in association with ILD (PH-ILD). Therefore, detailed history, physical examination, targeted serologic testing, and, occasionally, lung biopsy are needed to diagnose CTD-ILD, whereas both non-invasive and invasive assessments of pulmonary hemodynamics are needed to diagnose pulmonary hypertension. Immunosuppression is the mainstay of treatment for ILD, although data from randomized controlled trials (RCTs) to support specific treatments are lacking. Furthermore, treatment strategies vary according to the clinical situation-for example, the treatment of a patient newly diagnosed as having CTD-ILD differs from that of someone with an acute exacerbation of the disease. Immunosuppression is indicated only in select cases of pulmonary arterial hypertension related to CTD; more commonly, selective pulmonary vasodilators are used. For both diseases, comorbidities such as sleep disordered breathing, symptoms of dyspnea, and cough should be evaluated and treated. Lung transplantation should be considered in patients with advanced disease but is not always feasible because of other manifestations of CTD and comorbidities. Clinical trials of novel therapies including immunosuppressive therapies are needed to inform best treatment strategies.

Abstract
The management of connective tissue disease-associated interstitial lung disease (CTD-ILD) is complex and this arena offers many challenges to the practicing clinician. Unfortunately, treatment strategies and recommendations are often based on experience rather than evidence, and there are few effective therapeutic options. Pharmacologic intervention with immunosuppression is usually the mainstay of therapy and is reserved for those with clinically significant and/or progressive ILD. There is a desperate need for controlled trials across the spectrum of CTD-ILD and a number of potentially promising novel therapies warrant further study. It is important to address co-morbid conditions or aggravating factors (e.g., gastroesophageal reflux, aspiration, bone health, pulmonary hypertension, Pneumocystis jiroveci prophylaxis) and to institute non-pharmacologic management strategies (e.g., supplemental oxygen and cardiopulmonary rehabilitation) as part of a comprehensive treatment plan in CTD-ILD.

Abstract
Systemic sclerosis is a complex disease due to the variety of clinical presentations, often superimposed on other conditions, related or not to the connective tissue. We report a 43-year-old Brazilian woman with limited systemic sclerosis and pulmonary symptoms secondary to gastroesophageal reflux disease, with a clinical presentation similar to a diffuse interstitial lung disease. Because of the frequency of interstitial lung injury due to systemic sclerosis, this was an important differential diagnosis, which could be excluded after optimized treatment of reflux disease, with clinical and radiological improvement. Clinical management of patients with collagen diseases requires clinician skills to identify the natural history and understand its nuances. This is a common situation in clinical practice, but with a few discussions in international literature.

Abstract
Symptoms of heartburn and dysphagia as well as objective findings of abnormal esophageal acid exposure and esophageal dysmotility are common in patients with systemic sclerosis (SSc). Treatments for SSc esophageal disease are generally limited to gastroesophageal reflux disease (GERD) treatment with proton pump inhibitors. Progresses made in esophageal diagnostic testing offer the potential for improved clinical characterization of esophageal disease in SSc that may help direct management decisions. In addition to reviewing GERD management in patients with SSc, present and potential uses of endoscopy, reflux monitoring, manometry, impedance planimetry, and endoscopic ultrasound are discussed.

PURPOSE OF REVIEW The gastrointestinal tract is the most common extra-cutaneous organ system involved with systemic sclerosis (SSc) affecting approximately 90% of patients. This review summarizes the recent advances in the evaluation and management of gastrointestinal manifestations of SSc. RECENT FINDINGS There is a growing body of evidence that uncontrolled GERD can play a significant role in the pathogenesis of SSc-associated interstitial lung disease. Newer forms of management of Barrett esophagus are showing significant promise as potentially curative therapy. Gastric antral vascular ectasias have strongly been associated with the presence of RNA polymerase III antibody. Newer technologies have advanced the assessment of gastrointestinal dysmotility in SSc. Evidence of probiotic use for the treatment of gastrointestinal complications is emerging. The UCLA SCTC GIT 2.0 questionnaire is being increasingly accepted by the SSc experts as a validated instrument for evaluation of patient-reported outcomes involving the gastrointestinal tract. SUMMARY Our knowledge of the complex pathogenesis of gastrointestinal manifestations of SSc has expanded substantially in the last few decades. There has also been considerable technological progress in the evaluation of these manifestations. Patient care is being optimized by close collaboration of rheumatologists and gastroenterologists, leading to a more coordinated approach in the management of these complications.

Abstract
The gastrointestinal tract, affecting more than 90% of patients, is the internal organ most frequently involved in systemic sclerosis. Any part of the gastrointestinal tract can be affected, from the mouth to the anus. Patients often experience reduced quality of life and impaired social life. Although only 8% have severe gastrointestinal involvement, mortality is high in those patients. Recent studies on the pathophysiology of the disease highlight new mechanisms to explain gastrointestinal dysmotility, but treatment remains symptomatic. This article reviews the pathophysiology of the gastrointestinal tract and discusses the investigation and management of the disease.

Abstract
Gastrointestinal tract (GIT) commonly affects patients with systemic sclerosis (SSc). The GI involvement is quite heterogeneous varying from asymptomatic disease to significant dysmotility causing complications like malabsorption, weight loss and severe malnutrition. This review focuses on the management of GI involvement in SSc and has been categorized based on the segment of GIT involved. A brief discussion on the role of patient reported outcome measures in SSc-GI involvement has also been incorporated.

Abstract
PURPOSE OF REVIEW Systemic sclerosis (SSc), or scleroderma, is a heterogeneous and complex autoimmune disease characterized by varying degrees of skin and organ fibrosis and obliterative vasculopathy. The disease results in significant morbidity and mortality, and to date, available treatments are limited. Lung involvement is the leading cause of death of patients with SSc. Over the past year, significant advances have been made in our understanding of SSc-associated lung disease, and this review attempts to encapsulate these most recent findings and place them in context. RECENT FINDINGS We divide our discussion of the most recent literature into the following: first, clinical aspects of SSc lung management, including classification, imaging, biomarkers, and treatment; second, promising new animal models that may improve our ability to accurately study this disease; and third, studies that advance or change our understanding of SSc lung disease pathogenesis, thereby raising the potential for new targets for therapeutic intervention. SUMMARY Recent advances have resulted in a better understanding of SSc-associated lung disease, the development of new in-vivo models for exploring disease pathogenesis, and the identification of potential novel targets for the development of therapies.

Abstract
Restrictive lung disease leads to ventilatory defects and diffusion impairments. These changes may contribute to abnormal nocturnal pathophysiology, including sleep architecture disruption and impaired ventilation and oxygenation. Patients with restrictive lung disease may suffer significant daytime fatigue and dysfunction. Hypercarbia and hypoxemia during sleep may impact progression of lung disease and related symptoms. Little is known about the impact of treatment of sleep disruption on sleep quality and overall prognosis in restrictive lung disease. This review discusses the pathophysiology of sleep and comorbid sleep disorders in restrictive lung diseases including interstitial lung disease, neuromuscular disease, and obesity hypoventilation syndrome.

Abstract
OBJECTIVE The objective of this article was to establish the clinical course of interstitial lung disease (ILD) in scleroderma related to the presence of anti-PM/Scl antibody compared with anti-Scl-70 in a Spanish cohort. Furthermore, no study has thoroughly investigated the outcome of pulmonary function test in the first group of patients. METHODS A total of 63 Spanish patients with scleroderma and ILD were selected in a retrospective observational study. Among them, 14 were positive for anti-PM/Scl antibodies and 49 for anti-Scl-70. Clinical assessments, including pulmonary function test, were collected. Variations equal or greater than 10% in forced vital capacity (FVC) were considered significant. Progression-free survival of disease was defined as the period of stable illness since pulmonary fibrosis diagnosis. RESULTS Anti-Scl-70 patients had a higher frequency of diffuse SSc subset, peripheral vasculopathy, and gastrointestinal involvement. Inflammatory myopathy was associated to anti-PM/Scl antibody. Anti-PM/Scl patients presented more improvement in FVC during follow-up, 30.8% compared to a 7.1% in Scl-70 group (P = 0.04), with less worsening of this parameter (15.4% vs 52.4% in Scl-70 patients, P = 0.01), and secondary less frequency of severe restrictive pattern (FVC < 50%) (7.7% compared to 42.9% in the other group, P = 0.02). Regarding treatment, more anticalcineurinics were used in anti-PM/Scl patients, while cyclophosphamide and mycophenolate were mainly used in anti-Scl-70 patients. The progression-free survival of disease was higher in anti-PM/Scl patients, with 76% at 10 years from diagnosis of ILD against a 29% in the Scl-70 group. CONCLUSIONS Several features and prognosis of ILD in SSc may be modified depending on the identified immunological profile.
