Hu J, Deng Y, Dai P, Xie DW, Lan WF, Tan XL. Prognostic impact of right atrial strain in systemic lupus erythematosus with pulmonary arterial hypertension. Echocardiography 2024; 41:e15921. [PMID: 39254093 DOI: 10.1111/echo.15921] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2024] [Revised: 07/25/2024] [Accepted: 08/23/2024] [Indexed: 09/11/2024] Open
Abstract
OBJECTIVE The aim of this study was to assess right atrial (RA) function, including RA phase strain, via speckle-tracking echocardiography (STE) in a cohort of systemic lupus erythematosus (SLE) patients with pulmonary arterial hypertension (PAH) and in particular to explore the relationship between RA phase strain and the occurrence of cardiovascular events. METHODS STE analyses of RA function were evaluated in patients with SLE-PAH and in 33 healthy control subjects. Clinical associations, serum biomarkers, echocardiographic data, survival times, and adverse cardiovascular events were evaluated. RESULTS A total of 66 patients with SLE-PAH were enrolled; they were divided into two groups based on the occurrence of adverse clinical events. RA phase strain was significantly reduced in patients with events than in patients without events. The endpoint was defined as the combined outcome of all-cause mortality, right heart failure, and rehospitalization due to disease progression. During a mean follow-up of 17.2 ± 9.9 months, 23 patients (35%) reached the endpoint. Compared with patients with RA reservoir strain (RASr) ≥33.45%, patients with RASr < 33.45% had more adverse long-term outcomes (log rank p < .0001). RASr was independently associated with adverse clinical outcomes according to multivariate analysis (p = .010). CONCLUSION Our data suggest that RA function has prognostic value for SLE-PAH patients, and strain analysis revealed that the worse the RA function is, the worse the prognosis.

Rheumatol Adv Pract 2024; 8:rkae086. [PMID: 39224144 PMCID: PMC11368408 DOI: 10.1093/rap/rkae086] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2024] [Accepted: 07/01/2024] [Indexed: 09/04/2024] Open
Abstract
Objectives To comprehensively review systematic reviews of prevalence, incidence, and mortality of Raynaud's, Sjögren's and Scleroderma, and to identify any research gaps. Methods An umbrella review of English language systematic reviews was undertaken using PubMed and Embase (OVID) covering the period 2000-2023 (PROSPERO CRD42023434865). The estimate and its corresponding 95% confidence interval were reported when available from each systematic review. The quality of systematic reviews was assessed using the Scottish Intercollegiate Guidelines Network (SIGN) tool. A narrative synthesis was undertaken. Results Seventeen systematic reviews were identified, of which 1 was for RP, 5 for Sjögren's and 11 for Scleroderma. There were some high-quality systematic reviews for Sjögren's and mortality of Scleroderma. However, there were only low-quality systematic reviews of prevalence and incidence of RP and Scleroderma. Furthermore, there were no systematic reviews for the mortality of RP. For RP, the pooled prevalence was 4850 per 100 000; pooled annual incidence was 250 per 100 000. For Sjögren's, prevalence was 60-70 per 100 000; annual incidence was 6.92 per 100 000 and the pooled standardized mortality ratio ranged from 1.38 to 1.48. For Scleroderma, pooled prevalence ranged from 17.6 to 23 per 100 000; annual incidence was 1.4 per 100 000; and the pooled standardized mortality ratio ranged from 2.72 to 3.53. Conclusion The outcomes of RP were less well described compared with Sjögren's and Scleroderma. There was a lack of high-quality systematic reviews for the prevalence and incidence of RP and Scleroderma. Therefore, further studies and systematic reviews with rigorous case definitions, assessing different ethnic groups are warranted in this area.

Abstract
OBJECTIVE To describe the frequency of progressive pulmonary fibrosis (PPF) in an incident cohort of systemic sclerosis (SSc)-related interstitial lung disease (ILD) and its impact on survival. METHODS Incident ILD was defined as the new development of characteristic fibrotic changes on chest HRCT scan. PPF was defined as per the 2022 American Thoracic Society. Determinants of PPF were identified using generalised estimating equations. Impact on survival was analysed using accelerated failure time regression modelling. RESULTS Of our incident SSc-ILD cases, 38.8% (n = 180) experienced PPF within a 12-month period after ILD diagnosis. Determinants of PPF included older age (OR 1.02, 95%CI 1.00-1.03, P = 0.011), dcSSc (OR 1.54, 95% CI 1.06-2.25, P = 0.024) and SSc-specific antibodies (anticentomere antibody OR 0.51, 95%CI 0.29-0.91, P = 0.021 and anti-Scl-70 antibody OR 1.46, 95%CI 1.01-2.09, P = 0.043). Raised CRP was numerically associated with PPF but did not reach statistical significance (OR 1.29, 95%CI 0.99-1.68, P = 0.064) nor did GORD or dysphagia (OR 1.18, 95%CI 0.57-2.42, P = 0.658 and OR 1.17, 95%CI 0.57-2.40, P = 0.664, respectively). The presence of PPF significantly impacted survival in SSc-ILD (hazard ratio 2.66, 95%CI 1.59-4.41, P < 0.001). CONCLUSIONS PPF occurred in a third of our incident SSc-ILD cohort; however, its occurrence was significantly associated with mortality indicating an at-risk group who may be suitable for earlier introduction of immunosuppressive and/or antifibrotic therapy.

Abstract
Scleroderma is a chronic and progressive autoimmune disorder of connective tissues often causing lesions and deformities of the hands. Individuals affected by this condition experience daily life limitations and are typically unable to take part in sport activities that involve impacts on the hands. In this article we describe the design and manufacturing of custom-made hand orthoses to play sitting volleyball, for an elite paralympic athlete affected by scleroderma. The devices consist of a carbon fibre shell with an internal silicone padding and an external polymeric multilayer cover. The manufacturing of the orthoses involves digital modelling, 3D printing, composite lamination and an innovative method to create a strong and durable chemical bonding between silicone and carbon fibre. The internal silicone padding proved to be effective in hosting and protecting the hands, whereas the external shell with polymeric multilayer cover allowed to dampen the ball shocks while effectively hitting the ball. Indeed, these devices allowed the athlete to take part in the 2020 Tokyo Paralympic games and were used for two years without showing any damage.

Abstract
Autoimmune diseases such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and inflammatory bowel disease (IBD) are caused by the body's immune response to autoantigens. The pathogenesis of autoimmune diseases is unclear. Numerous studies have demonstrated that RNA methylation plays a key role in disease progression, which is essential for post-transcriptional regulation and has gradually become a broad regulatory mechanism that controls gene expression in various physiological processes, including RNA nuclear output, translation, splicing, and noncoding RNA processing. Here, we outline the writers, erasers, and readers of RNA methylation, including N6-methyladenosine (m6A), 2'-O-methylation (Nm), 2'-O-dimethyladenosine (m6Am), N1-methyladenosine (m1A), 5-methylcytidine (m5C) and N7-methylguanosine (m7G). As the role of RNA methylation modifications in the immune system and diseases is explained, the potential treatment value of these modifications has also been demonstrated. This review reports the relationship between RNA methylation and autoimmune diseases, highlighting the need for future research into the therapeutic potential of RNA modifications.

The role of lung biopsy for diagnosis and prognosis of interstitial lung disease in systemic sclerosis: a systematic literature review. Respir Res 2024; 25:138. [PMID: 38521926 PMCID: PMC10960984 DOI: 10.1186/s12931-024-02725-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Accepted: 02/12/2024] [Indexed: 03/25/2024] Open
Abstract
BACKGROUND The prognostic and theragnostic role of histopathological subsets in systemic sclerosis interstitial lung disease (SSc-ILD) have been largely neglected due to the paucity of treatment options and the risks associated with surgical lung biopsy. The novel drugs for the treatment of ILDs and the availability of transbronchial cryobiopsy provide a new clinical scenario making lung biopsy more feasible and a pivotal guide for treatment. The aim of our study was to investigate the usefulness of lung biopsy in SSc ILD with a systematic literature review (SLR). METHODS PubMed, Embase and Cochrane databases were searched up to June 30, 2023. Search terms included both database-specific controlled vocabulary terms and free-text terms relating to lung biopsy and SSc-ILD diagnostic and prognosis. The SLR was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA). Studies were selected according to the PEO (population, exposure, and outcomes) framework and Quality assessment of diagnostic accuracy studies (QUADAS) were reported. RESULTS We selected 14 articles (comprising 364 SSc-ILD patients). The paucity and heterogeneity of the studies prevented a systematic analysis. Diffuse cutaneous SSc was present in 30-100% of cases. Female predominance was observed in all studies (ranging from 64 to 100%). Mean age ranged from 42 to 64 years. Mean FVC was 73.98 (+/-17.3), mean DLCO was 59.49 (+/-16.1). Anti-Scl70 antibodies positivity was detected in 33% of cases (range: 0-69.6). All patients underwent surgical lung biopsies, and multiple lobes were biopsied in a minority of studies (4/14). Poor HRCT-pathologic correlation was reported with HRCT-NSIP showing histopathologic UIP in up to 1/3 of cases. Limited data suggest that SSc-UIP patients may have a worse prognosis and response to immunosuppressive treatment compared to other histopathologic patterns. CONCLUSIONS The data from this SLR clearly show the paucity and heterogeneity of the studies reporting lung biopsy in SSc ILD. Moreover, they highlight the need for further research to address whether the lung biopsy can be helpful to refine prognostic prediction and guide therapeutic choices.

Abstract
OBJECTIVE In the last decades, the number of foreigners in Tuscany has considerably increased with a multiethnic distribution. We reviewed the main rheumatic diseases in the foreign population resident in Tuscany and also reported the experience at the Rheumatology Division of the University Hospital of Careggi, Florence, in order to identify the areas of origin of these patients and the main rheumatic diseases observed in them. METHODS The collaboration with the Tuscan Region provided data about foreign patients residing in Tuscany on January 1, 2021 (country of origin, chronic diseases). Moreover, we conducted a retrospective review of the clinical charts of our Rheumatologic Division from January 1, 2019, to December 31, 2020. RESULTS In Tuscany, on January 1, 2021, there were 61,373 patients with chronic inflammatory rheumatic diseases, and 3994 of them (6.51%) were foreigners. Most patients were born in Europe (39.03%), followed by the Balkans (15%), South America (11.27%), and North Africa (10.31%). Inflammatory joint diseases, Sjögren syndrome, and systemic lupus erythematosus were the most frequent diseases. In the period 2019-2020, 511 foreign patients visited our Rheumatology Division and mainly originated from the Balkans (34.64%), South America (18%), and European countries (16.44%). In these patients, chronic inflammatory joint diseases and connective tissue diseases (systemic sclerosis, Sjögren syndrome, and systemic lupus erythematosus) were the most prevalent diseases. CONCLUSIONS This study provides a picture of the rheumatic diseases affecting foreign patients residing in Tuscany that are in agreement with the epidemiological data previously provided.

Abstract
BACKGROUND m6A regulators have important roles in a variety of autoimmune diseases, but their potential function in scleroderma, a refractory connective tissue disease, remains unclear. Tenascin C (TNC) is known to be a factor promoting collagen deposition in the development of scleroderma, but the regulatory relationship between TNC and m6A regulators is unknown. METHODS We extracted GSE33463 data consisting of forty-one healthy controls and sixty-one patients with scleroderma, and we analyzed the expression levels of twenty-one m6A regulators as well as the associations between them. In addition, we obtained random forest (RF) and nomogram models to predict the likehood of scleroderma. Next, we categorized the m6Aclusters and geneclusters by consensus clustering, and we performed an immune cell infiltration analysis for each cluster. Finally, we injected adenoviruses into a bleomycin (BLM)-induced mouse model of scleroderma, which was used to overexpress FTO and TNC. We assess the extent of skin fibrosis in the mice samples using pathology stains and measuring their hydroxyproline content and collagen mRNA. RESULTS We initially identified fourteen differentially expressed m6A regulators (WTAP, RBM15, CBLL1, FTO, ALKBH5, YTHDC1, YTHDC2, YTHDF1, YTHDF2, YTHDF3, RBMX, HNRNPC, IGFBP1 and IGFBP2). We found ALKBH5 to be positively associated with CBLL1 and RBM15, and FTO to be negatively associated with WTAP. In addition, we identified four m6A regulators (CBLL1, IGFBP1, YTHDF2 and IGFBP2) using a RF model, and we designed a nomogram model with those variables that proved reliable according to the calibration curve and clinical impact curve. We found that the m6Acluster A was correlated with Type 1 T helper cell infiltration and the genecluster A was correlated with regulatory T cell infiltration. Finally, we showed that FTO overexpression downregulated the m6A and mRNA levels of TNC, and alleviated skin fibrosis in the mouse model of scleroderma. Thus, our overexpression experiments provide preliminary evidence suggesting that TNC is an adverse factor in scleroderma. CONCLUSION Our approach might be useful as a new and accurate scleroderma diagnosis method. Moreover, our results suggested that FTO/TNC might be a novel scleroderma therapeutic target.

Abstract
OBJECTIVE To describe the health care resource use (HCRU) and costs of patients with systemic sclerosis (SSc) prior to and after diagnosis. METHODS This retrospective study used a claims data set (Merative MarketScan; 2015-2019). Eligible patients with SSc were identified by diagnosis codes and required at least 24 months of enrollment without an SSc diagnosis before their first SSc claim and at least 12 months of enrollment thereafter. Total HCRU and costs were reported for three intervals: 2 years and 1 year before and 1 year after index diagnosis. A general population cohort without SSc was matched 1:1 to the SSC cohort on age and sex for comparison. RESULTS Eligibility criteria identified 902 patients with SSc (mean age: 54 years old; 85% female). Mean per-member per year costs increased each year from $22,383 to $29,708 to $47,095, 2 years before, 1 year before, and 1 year after index diagnosis versus $10,232 to $9656 to $9714 in the general population cohort. Outpatient settings represented the largest proportion of cost 1 year after SSc diagnosis ($16,392), followed by prescription drugs ($10,692), physician office ($10,523), and inpatient ($9448) settings. CONCLUSION Patients with SSC accrued greater costs and required more services than a general population cohort. These elevated expenditures and HCRU were observed at least 2 years before an SSc diagnosis and increased over time, reflecting both the progressive, multisystem nature of SSc and potential challenges in diagnosis. These findings suggest that SSc poses a substantial burden on the US health care system and highlights the need for early diagnosis and effective therapies.

Wang Q, Li CL, Wu L, Hu JY, Yu Q, Zhang SX, He PF. Distinct molecular subtypes of systemic sclerosis and gene signature with diagnostic capability. Front Immunol 2023; 14:1257802. [PMID: 37849750 PMCID: PMC10577296 DOI: 10.3389/fimmu.2023.1257802] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Accepted: 09/19/2023] [Indexed: 10/19/2023] Open
Abstract
Background As Systemic Sclerosis (SSc) is a connective tissue ailment that impacts various bodily systems. The study aims to clarify the molecular subtypes of SSc, with the ultimate objective of establishing a diagnostic model that can inform clinical treatment decisions. Methods Five microarray datasets of SSc were retrieved from the GEO database. To eliminate batch effects, the combat algorithm was applied. Immune cell infiltration was evaluated using the xCell algorithm. The ConsensusClusterPlus algorithm was utilized to identify SSc subtypes. Limma was used to determine differential expression genes (DEGs). GSEA was used to determine pathway enrichment. A support vector machine (SVM), Random Forest(RF), Boruta and LASSO algorithm have been used to select the feature gene. Diagnostic models were developed using SVM, RF, and Logistic Regression (LR). A ROC curve was used to evaluate the performance of the model. The compound-gene relationship was obtained from the Comparative Toxicogenomics Database (CTD). Results The identification of three immune subtypes in SSc samples was based on the expression profiles of immune cells. The utilization of 19 key intersectional DEGs among subtypes facilitated the classification of SSc patients into three robust subtypes (gene_ClusterA-C). Gene_ClusterA exhibited significant enrichment of B cells, while gene_ClusterC showed significant enrichment of monocytes. Moderate activation of various immune cells was observed in gene_ClusterB. We identified 8 feature genes. The SVM model demonstrating superior diagnostic performance. Furthermore, correlation analysis revealed a robust association between the feature genes and immune cells. Eight pertinent compounds, namely methotrexate, resveratrol, paclitaxel, trichloroethylene, formaldehyde, silicon dioxide, benzene, and tetrachloroethylene, were identified from the CTD. Conclusion The present study has effectively devised an innovative molecular subtyping methodology for patients with SSc and a diagnostic model based on machine learning to aid in clinical treatment. The study has identified potential molecular targets for therapy, thereby offering novel perspectives for the treatment and investigation of SSc.

Chiu YH, Drijver A, Admiraal R, van Rhenen A, Nierkens S, van Laar JM, Spierings J. Anti-thymocyte globulin exposure in patients with diffuse cutaneous systemic sclerosis undergoing autologous haematopoietic stem cell transplantation. JOURNAL OF SCLERODERMA AND RELATED DISORDERS 2023; 8:241-246. [PMID: 37744043 PMCID: PMC10515999 DOI: 10.1177/23971983231188232] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Accepted: 06/28/2023] [Indexed: 09/26/2023]
Abstract
Introduction Autologous haematopoietic stem cell transplantation improves event-free survival and lung function and reduces skin thickening in patients with progressive diffuse cutaneous systemic sclerosis. Anti-thymocyte globulin is a key lymphoablative constituent of conditioning protocols and is administered in a weight-based dosage. However, whether anti-thymocyte globulin exposure contributes to response to autologous haematopoietic stem cell transplantation and lymphocyte reconstitution in diffuse cutaneous systemic sclerosis patients is unknown. We aimed to explore the relationship between anti-thymocyte globulin exposure, lymphocyte reconstitution and treatment response in diffuse cutaneous systemic sclerosis patients undergoing autologous haematopoietic stem cell transplantation. Methods A retrospective cohort of 15 diffuse cutaneous systemic sclerosis patients undergoing autologous haematopoietic stem cell transplantation was performed. Clinical characteristics and routine laboratory results were retrieved from electronic medical records. Anti-thymocyte globulin concentrations were measured in cryopreserved plasma samples at four time points (day 1 and week 1, 2 and 4) after stem cell reinfusion. Anti-thymocyte globulin exposure was estimated using a validated population pharmacokinetic model. Results During a median follow-up of 45 months (interquartile range 19-66), 11 (73%) patients had a treatment response, and 4 (27%) were non-responders. Although all patients received the same weight-based anti-thymocyte globulin dosage, 7.5 mg/kg divided over 3 days, anti-thymocyte globulin exposure varied. Anti-thymocyte globulin exposure was higher in responders than in non-responders (163 AU*day/mL (interquartile range 153-183) and 137 AU*day/mL (interquartile range 101-149), respectively, p = .026). Anti-thymocyte globulin exposure was not correlated with lymphocyte reconstitution or infection rate. Conclusion Weight-based dosing of anti-thymocyte globulin results in variable anti-thymocyte globulin exposure and treatment response across individuals.

Retrospective comparative study of the efficacy of JAK inhibitor (tofacitinib) in the treatment of systemic sclerosis-associated interstitial lung disease. Clin Rheumatol 2023; 42:2823-2832. [PMID: 37335409 DOI: 10.1007/s10067-023-06660-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Revised: 04/05/2023] [Accepted: 06/01/2023] [Indexed: 06/21/2023]
Abstract
The oral Janus kinases inhibitor (JAKi) has improved the management of skin manifestations in systemic sclerosis (SSc), and our study aimed to explore the efficacy of non-selective JAKi tofacitinib in ameliorating interstitial lung disease (ILD) in the patients with SSc. The hospitalization data of the SSc-ILD patients from April 2019 to April 2021 were collected, and the changes of pulmonary function and the radiological findings in pulmonary high-resolution CT (HRCT) from the 9 patients who received tofacitinib for at least 6 months and a matched group of 35 SSc-ILD patients treated with conventional immunosuppressants or glucocorticoids, were compared and analyzed. There were no significant differences in demographic data and clinical characteristics between the tofacitinib-treated group (tofa-group) and the matched group. However, in the tofa-group, the changes in serum lactate dehydrogenase (LDH) concentration and serum interleukin-6 levels were significantly lower than those in the matched group. Moreover, the tofa-group showed amelioration in decreased diffusing capacity of the lung for carbon monoxide (DLCO) (62.05 ± 9.47 vs. 66.61 ± 12.39, p = 0.046), reductions in ground-glass attenuation involvement (1.00 ± 0.86 vs. 0.33 ± 0.50, p = 0.024) and irregular pleural thickening (1.33 ± 0.50 vs. 0.67 ± 0.51, p = 0.004) in pulmonary HRCTs, alleviated modified Rodnan skin score (mRSS) of skin sclerosis (9.22 ± 3.81 vs. 7.11 ± 3.92, p = 0.048), and reduced HRCT scores of pulmonary fibrosis (15.00 ± 3.87 vs. 12.66 ± 4.92, p = 0.009). Logistic regression analysis showed that the involvement of ground-glass attenuation (OR 11.43) and the add-on therapy of tofacitinib (OR 9.98) were the relevant factors in the amelioration of HRCT. Our results indicate that the use of JAKi (tofacitinib) may be relevant to significant improvement of the sclerosis and early radiological abnormalities in SSc-ILD patients. Further studies are needed to confirm these findings and to explore its efficacy more precisely. Key Points • The currently available therapies for SSc-ILD have limited therapeutic benefits. • The add-on therapy of the oral JAK inhibitor is available in the real world. • The tofacitinib was promising in the improvement of the sclerosis and early radiological abnormalities in SSc-ILD patients.

Abstract
Systemic sclerosis is a progressive connective tissue disease for which there is limited knowledge about physical limitations, quality of life and depression. The aim of this study was to assess these parameters during the disease process of systemic sclerosis, in a cross- sectional study of 79 patients and a longitudinal study of 33 patients over 10 years. Medical data were collected by physicians' questionnaires and sociodemographic data, pain, physical limitation, quality of life, subjective health status, risk of depressive symptoms by patients' questionnaires. Data analysis was descriptive and exploratory. Cross-tabulations, χ2 test and Student's t-test were used for calculations, Pearson's correlation to measure dependencies, and logistic regression analyses for categorized parameters. The cross-sectional analysis of 79 patients with systemic sclerosis (81% female, mean ± standard deviation age 61.5 ± 12.6 years) demonstrated a higher rate of patients with risk of depressive symptoms (42.3%) higher physical limitations, lower quality of life, and subjective health status than reference values for the general German population. Moderate to strong correlations between disease-related physical limitation, quality of life, subjective health status, risk of depressive symptoms and pain were detected (correlation according to Pearson -0.459 to -0.638, p < 0.001). Longitudinal analysis revealed a significant increase in disease activity, pain, physical limitation and risk of depressive symptoms (p < 0.001) during the disease process. This study demonstrates that nearly half of patients with systemic sclerosis probably experience depressive symptoms. The rate of patients with risk of depressive symptoms, pain and physical limitations increased during the systemic sclerosis disease process. Health-related quality of life and state of health declined, indicating the need for better interdisciplinary care for patients with systemic sclerosis.

Abstract
BACKGROUND/OBJECTIVE The purpose of this qualitative study was to provide insight into the changes and barriers to leisure experienced by people with scleroderma. METHOD Twenty-five people with scleroderma consented to be interviewed via telephone using a semi-structured interview. The conversations were audio recorded and transcribed verbatim. Thorne's Interpretive Description informed the analysis process. RESULTS Three themes emerged from the analysis: barriers to leisure participation (impact of Raynaud's Phenomenon symptoms, fatigue, changes in body structures and functions, unpredictability of daily symptoms and selection of leisure activities), decreases in leisure participation (less time outdoors, reduction in time spent in active leisure, more time spent in passive leisure) and experiences of losing a valued leisure activity (depressed mood, identity change, fear of loss and sense of isolation). CONCLUSIONS The changes in leisure participation found in this study were reported to be due to the rate of disease progression and the severity of disease symptoms, particularly, Raynaud symptoms and fatigue. Health professionals should work with people with SSc to facilitate participation in valued leisure activities.

Abstract
BACKGROUND Sex and gender have increasingly been recognized as significant risk factors for many diseases, including dermatological conditions. Historically, sex and gender have often been grouped together as a single risk factor in the scientific literature. However, both may have a distinct impact on disease incidence, prevalence, clinical presentation, severity, therapeutic response, and associated psychological distress. OBJECTIVES AND PROJECT DESCRIPTION The mechanisms that underlie differences in skin diseases between males, females, men, and women remain largely unknown. The specific objectives of this review paper are:To highlight the biological differences between males and females (sex), as well as the sociocultural differences between men and women (gender) and how they impact the integumentary system.To perform a literature review to identify important sex- and gender-related epidemiological and clinical differences for various skin conditions belonging to a range of disease categories and to discuss possible biological and sociocultural factors that could explain the observed differences.To discuss dermatological skin conditions and gender-affirming treatments within the transgender community, a population of individuals who have a gender identity which is different than the gender identity they were assigned at birth. FUTURE IMPACT With the rising number of individuals that identify as non-binary or transgender within our increasingly diverse communities, it is imperative to recognize gender identity, gender, and sex as distinct entities. By doing so, clinicians will be able to better risk-stratify their patients and select treatments that are most aligned with their values. To our knowledge, very few studies have separated sex and gender as two distinct risk factors within the dermatology literature. Our article also has the potential to help guide future prevention strategies that are patient-tailored rather than using a universal approach.

Abstract
Puffy fingers and Raynaud's phenomenon (RP) are important clinical predictors of the development of systemic sclerosis (SSc). We aim to assess the prevalence of SSc-related symptoms, explore pulmonary symptoms, and test the usefulness of skin autofluorescence (SAF) as a non-invasive marker for Advanced Glycation Endproducts (AGEs). Subjects from the Lifelines Cohort Study with known connective tissue disease (CTD) were excluded. Patient characteristics, SAF, self-reported pulmonary symptoms, and spirometry were obtained. Subjects (n = 73,948) were categorized into definite RP (5.3%) with and without SSc-related symptoms and non-RP. Prevalence of at least one potential SSc-related symptom (other than RP) was 8.7%; 23.5% in subjects with RP and 7.1% without RP (p < 0.001). Subjects with RP and additional SSc-related symptoms more frequently reported dyspnea at rest, dyspnea after exertion, and self-reported pulmonary fibrosis, and had the lowest mean forced vital capacity compared to the other groups (RP without SSc-related symptoms and no RP, both p < 0.001). In multivariate regression, dyspnea at rest/on exertion remained associated with an increased risk of SSc-related symptoms in subjects with RP (both p < 0.001). SAF was higher in subjects with RP and SSc-related symptoms compared to the other groups (p < 0.001), but this difference was not significant after correction for potential confounders. The prevalence of SSc-related symptoms was approximately three-fold higher in subjects with RP. Pulmonary symptoms are more prevalent in subjects with RP who also reported additional potential SSc-related symptoms. This might suggest that (suspected) early SSc develops more insidiously than acknowledged. According to this study, SAF is no marker for early detection of SSc.

Abstract
Systemic sclerosis (SSc) is a rare systemic autoimmune disease, characterized by the presence of three main actors: vasculopathy, immune activation, and fibrosis. This pathologic process is then translated in a clinical picture with great variability among different patients in terms of type of organ involvement, disease severity and prognosis. This heterogeneity is a main feature of SSc, which, in addition to the presence of early phases of the disease characterized by mild symptoms, can explain the high difficulty in establishing classification criteria, and in defining patients' subsets and disease outcomes. The definition of disease outcomes is particularly relevant in the setting of clinical trials, where the aim is to provide reliable endpoints, able to measure the magnitude of the efficacy of a certain drug or intervention. For this reason, in the last years, increasing efforts have been done to design measures of disease activity, damage, severity, and response to treatment, often in the context of composite indexes. When considering disease outcomes, the experience of the patient represents a relevant and complementary aspect. The tools able to capture this experience, the patient-reported outcomes, have been increasingly used in the last years in clinical practice and in clinical trials, both as primary and secondary endpoints. This comprehensive narrative review on SSc will therefore cover pathogenetic and histopathologic aspects, epidemiology, classification systems, and disease outcome measures, in order to focus on issues that are relevant for clinical research and design of clinical trials.

Abstract
Dry eye disease is a chronic disease of the ocular surface characterized by abnormal tear film composition, tear film instability, and ocular surface inflammation, affecting 5% to 50% of the population worldwide. Autoimmune rheumatic diseases (ARDs) are systemic disorders with multi-organ involvement, including the eye, and play a significant role in dry eye. To date, most studies have focused on Sjögren's syndrome (one of the ARDs) since it manifests as two of the most common symptoms-dry eyes and a dry mouth-and attracts physicians to explore the relationship between dry eye and ARDs. Many patients complained of dry eye related symptoms before they were diagnosed with ARDs, and ocular surface malaise is a sensitive indicator of the severity of ARDs. In addition, ARD related dry eye is also associated with some retinal diseases directly or indirectly, which are described in this review. This review also summarizes the incidence, epidemiological characteristics, pathogenesis, and accompanying ocular lesions of ARD's related dry eye, emphasizing the potential role of dry eye in recognition and monitoring among ARDs patients.

Abstract
OBJECTIVES To estimate the global and country-specific unbiased epidemiological data of SSc. METHODS Epidemiological studies were systematically searched in four databases. A Bayesian hierarchical linear mixed model was constructed to estimate epidemiological data. RESULTS 82 studies were included and epidemiological data on SSc were missing for 83.9% of countries worldwide. The global SSc incidence and newly diagnosed population were estimated to be 8.64 per 100,000 person-years (1.78-23.57) and 0.67 million (0.14-1.84) people annually, respectively. Regarding prevalence, the global SSc prevalence and affected population were 18.87 per 100,000 persons (1.55-25.28) and 1.47 million (0.12-1.97) people, respectively. Relatively higher incidence and prevalence were observed in females, adults, and high-income level countries. CONCLUSIONS We provide a comprehensive synthesis of SSc epidemiology and fill data gaps in most countries. Especially in low- and middle-income countries, epidemiological studies of SSc are insufficient. Further large-scale and standardized reported epidemiological investigations of SSc are imperative.

Abstract
Objectives: In this study, we aimed to evaluate the factors associated with disability and quality of life (QoL) in Turkish patients with systemic sclerosis (SSc).
Patients and methods: Between January 2018 and January 2019, a total of 256 SSc patients (20 males, 236 females; mean age: 50.9±12.4 years; range, 19 to 87 years) who were diagnosed with SSc were included in the study. Disability and health-related QoL (HRQoL) were evaluated by the Health Assessment Questionnaire (HAQ), scleroderma HAQ (SHAQ), Duruöz Hand Index (DHI), and Short Form-36 (SF-36). Linear regression analysis methods were used to describe factors associated with disability and QoL of the patients.
Results: All disability scores were higher and HRQoL scores were lower in diffuse cutaneous SSc patients compared limited cutaneous SSc, and differentiations were significant (p=0.001 and p=0.007). In multiple regression, pain (VAS) was the strongest predictor for high disability and low QoL scores (p<0.001) as HAQ (β=0.397, 0.386, 0.452), SHAQ (β=0.397, 0.448, 0.372), DHI (β=0.446, 0.536, 0.389), PCS (β=-0.417,-0.499, -0.408) and MCS (β=-0.478, -0.441, -0.370) in combined, lcSSc and dcSSc patients respectively. The factors associated with high disability and low QoL scores were forced vital capacity for HAQ (β=-0.172, p=0.002) and SF-36 PCS (β=0.187, p=0.001); disease duration for HAQ (β=0.208, p<0.001), DHI (β=0.147, p=0.006), and SF-36 PCS (β=-0.134, p=0.014); 6-minute walk test for HAQ (β=-0.161, p=0.005) and SF-36 PCS (β=0.153, p=0.009); and modified Rodnan skin score for SHAQ (β=0.250, p<0.001) and DHI (β=0.233, p<0.001) in SSc patients. Diffusing capacity of the lungs for carbon monoxide for HAQ (β=-0.189, p=0.010) and SHAQ (β=-0.247, p=0.002); erythrocyte sedimentation rate for DHI (β=0.322, p<0.001); age for SF-36 PCS (β=-0.221, p=0.003) and body mass index for SF-36 PCS (β=-0.200, p=0.008) and MCS (β=-0.175, p=0.034) were the other variables associated with high disability or low QoL scores in SSc subsets.
Conclusion: Clinicians should consider the management of the pain and its sources as a key to improve better functional state and quality of daily life in SSc.

Abstract
Objective The aim of the present study was to compare periodontal status and antioxidant profile in unstimulated saliva of systemic sclerosis (SSc) patients with periodontitis and systemically healthy periodontitis patients. Design Twenty patients with established diagnoses of systemic sclerosis and periodontitis (SSc group) and 20 systemically healthy individuals with periodontitis (P group) were enrolled in the study. Clinical periodontal parameters (clinical attachment level (CAL), gingival recession (GR), periodontal probing depth (PPD), and gingival index (GI)) and concentration of uric acid (UA), superoxide dismutase (SOD), and glutathione peroxidase (GPX) in unstimulated saliva samples were assessed. Results There were significantly higher mean values of CAL (4.8 ± 0.21 mm versus 3.18 ± 0.17 mm; p ≤ 0.001) and GR (1.66 ± 0.90 mm versus 0.46 ± 0.54 mm; p ≤ 0.001) in the SSc group when compared to the P group. Significantly higher level of GPX (p ≤ 0.001) and SOD (p ≤ 0.001) in unstimulated saliva was detected in the SSc group in comparison with the P group. The specific activity of UA did not significantly differ between the two groups (p = 0.083). Conclusion The results may indicate higher periodontal destruction and antioxidant perturbations in unstimulated saliva of SSc patients with periodontitis compared to systemically healthy periodontitis patients.

Abstract
Connective tissue diseases (CTDs) are a heterogenous group of systemic inflammatory disorders. The development of connective tissue disease-associated interstitial lung disease (CTD-ILD) is a key complication associated with significant morbidity and mortality. The aim of this review is to explore the pathogenesis of CTD-ILD and summarize the recent evidence from clinical trials for novel treatment options, including the role of antifibrotics and immunomodulatory therapies with a focus on systemic sclerosis associated ILD. Further clinical trials are ongoing to explore combination therapies and more targeted therapeutic options. Clinicians remain faced with the difficult challenge of appropriately selecting patients who will benefit from the available therapies and timing the start of therapy at the most suitable part of the disease course.

Abstract
Abstract
Background
Pain, related to Raynaud’s phenomenon or digital ulceration, has been identified as very prevalent and debilitating symptoms of systemic sclerosis (SSc), both significantly affecting patients’ quality of life (QoL). Pharmacological therapeutic strategies were found not to be sufficiently effective in the management of SSc-induced pain and fatigue, and evidence for exercise is scarce. As yet, the effects of a long-term, tailored exercise programme on pain and fatigue in patients with SSc have not been explored. In addition to pain and fatigue, this study aims to evaluate the effects of exercise on QoL, physical fitness, functional capacity, and vascular structure in people with SSc (PwSSc).
Methods
This will be a multicentre (n = 6) randomised controlled clinical trial to assess the effect of a previously established, supervised 12-week combined exercise programme on pain and fatigue as compared to no exercise in PwSSc. The study will recruit 180 patients with SSc that will be allocated randomly to two groups. Group A will perform the exercise programme parallel to standard usual care and group B will receive usual care alone. Patients in the exercise group will undertake two, 45-min sessions each week consisting of 30-min high-intensity interval training (HIIT) (30-s 100% peak power output/30-s passive recovery) on an arm crank ergometer and 15 min of upper body circuit resistance training. Patients will be assessed before as well as at 3 and 6 months following randomisation. Primary outcomes of the study will be pain and fatigue assessed via questionnaires. Secondary outcomes include quality of life, structure of digital microvasculature, body composition, physical fitness, and functional capacity.
Discussion
Data from this multi-centre research clinical trial will primarily be used to establish the effectiveness of a combined exercise protocol to improve pain and fatigue in SSc. In parallel, this study will be the first to explore the effects of long-term exercise on potential microvascular alterations assessed via NVC. Overall, this study will provide sufficient data to inform current clinical practice guidelines and may lead to an improvement of QoL for patients with SSc.

Abstract
Interstitial lung diseases (ILD) are a group of heterogeneous progressive pulmonary disorders, characterised by tissue remodelling and/or fibrotic scarring of the lung parenchyma. ILD patients experience lung function decline with progressive symptoms, poor response to treatment, reduced quality of life and high mortality. ILD can be idiopathic or associated with systemic or connective tissue diseases (CTD) but idiopathic pulmonary fibrosis (IPF) is the most common form. While IPF has a male predominance, women are affected more greatly by CTD and therefore associated ILDs. The mechanisms behind biological sex differences in these progressive lung diseases remain unclear. However, differences in environmental exposures, variable expression of X-chromosome related inflammatory genes and sex hormones play a role. Here, we will outline sex-related differences in the incidence, progression and mechanisms of action of these diseases and discuss existing and novel cellular and pre-clinical studies. Furthermore, we will highlight how sex-differences are not adequately considered in pre-clinical disease models, how gender bias exists in clinical diagnosis and how women are underrepresented in clinical trials. Future action on these observations will hopefully shed light on the role of biological sex in disease development, identify potential targets for intervention and increase female participant numbers in clinical trials.

Abstract
Purpose To evaluate the prevalence of dry eye disease (DED) in patients with both limited and diffuse subtypes of systemic sclerosis (SSc) and to determine the predictive factors associated with the occurrence of DED. Patients and Methods This was a prospective consecutive cross-sectional study of patients with SSc. Each patient underwent a comprehensive ophthalmological evaluation. The Ocular Surface Disease Index (OSDI) was used to assess the symptoms of DED. Tear break up time (TBUT), Schirmer I and ocular surface staining (OSS) were used for objective tests. Patients were diagnosed DED using the DEW II diagnostic method which included both symptom and objective tests. The collected data of patients with and without DED were compared to find out possible associated factors. Logistic regression analysis was used to determine the effects of these factors. Results Eighty-four SSc patients (25 limited and 59 diffuse subtypes) were studied. The prevalence of DED in SSc patients was 52.38%. The OSDI, tear break up time (TBUT), Schirmer I and ocular surface staining (OSS) were not significantly different between SSc subtypes. Among the 46 symptomatic patients, DED was noted in 44 (52.38%). Most patients (61.4%) were mixed aqueous deficiency-evaporative dry eye type (both TBUT and Schirmer I test positive). The mean age and the median of disease duration in DED patients were higher than those without DED with statistically significant difference (P = 0.004 and 0.019). Conclusion DED was common in patients with SSc. The predictors for the occurrence of DED were older age and longer disease duration. Therefore, OSDI and objective tests for DED should be evaluated in all SSc patients, particularly those with older age and longer disease duration.

Abstract
Personalized medicine (PM) aims individualized approach to prevention, diagnosis, and treatment. Precision Medicine applies the paradigm of PM by defining groups of individuals with akin characteristics. Often the two terms have been used interchangeably. The quest for PM has been advancing for centuries as traditional nosology classification defines groups of clinical conditions with relatively similar prognoses and treatment options. However, any individual is characterized by a unique set of multiple characteristics and therefore the achievement of PM implies the determination of myriad demographic, epidemiological, clinical, laboratory, and imaging parameters. The accelerated identification of numerous biological variables associated with diverse health conditions contributes to the fulfillment of one of the pre-requisites for PM. The advent of multiplex analytical platforms contributes to the determination of thousands of biological parameters using minute amounts of serum or other biological matrixes. Finally, big data analysis and machine learning contribute to the processing and integration of the multiplexed data at the individual level, allowing for the personalized definition of susceptibility, diagnosis, prognosis, prevention, and treatment. Autoantibodies are traditional biomarkers for autoimmune diseases and can contribute to PM in many aspects, including identification of individuals at risk, early diagnosis, disease sub-phenotyping, definition of prognosis, and treatment, as well as monitoring disease activity. Herein we address how autoantibodies can promote PM in autoimmune diseases using the examples of systemic lupus erythematosus, antiphospholipid syndrome, rheumatoid arthritis, Sjögren syndrome, systemic sclerosis, idiopathic inflammatory myopathies, autoimmune hepatitis, primary biliary cholangitis, and autoimmune neurologic diseases.

Abstract
Systemic sclerosis (SSc) is an immune-mediated rheumatic disease characterized by vascular abnormalities, tissue fibrosis, and inflammation. Renal disease occurring in patients with SSc may have a variable clinicopathological picture. However, the most specific renal condition associated with this disease is the scleroderma renal crisis (SRC), characterized by acute onset of renal failure and severe hypertension. SRC develops in about 20% of cases of SSc, especially in those patients with diffuse cutaneous disease. The prognosis of this condition is often negative, with a rapid progression to end-stage renal disease (ESRD). The advent of the antihypertensive angiotensin-converting enzyme inhibitors in 1980 was associated with a significant improvement in patients’ survival and recovery of renal function. However, the prognosis of these patients can still be improved. The dialytic condition is associated with early death, and mortality is significantly higher than among patients undergoing renal replacement therapy (RRT) due to other conditions. Patients with SRC who show no signs of renal functional recovery despite timely blood pressure control are candidates for kidney transplantation (KT). In this review, we reported the most recent advances in KT in patients with ESRD due to SSc, with a particular overview of the risk of disease recurrence after transplantation and the evolution of other disease manifestations.

Abstract
OBJECTIVE Many indigenous non-Caucasian populations, including Native Americans, have been reported to have higher rates, distinct clinical phenotypes, increased complications, and greater severity of systemic sclerosis (SSc). However, little is known of SSc specifically in Native Americans of the American Southwest. This study compared the clinical and serologic manifestations and outcomes of SSc in Native Americans and non-Native Americans (non-Natives) of this region. METHODS This cross-sectional retrospective study included 137 SSc patients (109 [80%] were non-Native and 28 [20%] were Native Americans) followed over a mean of 11.5 ± 7.6 years. Participants were repetitively evaluated with medical history, physical examination, echocardiography, chest imaging, and serologic testing. Disease characteristics and outcomes were statistically compared between Native Americans and non-Native patients. RESULTS The estimated prevalence of SSc in Native Americans was 40.0 cases/100 000 vs 17.1 cases/100 000 for non-Natives (odds ratio 2.34, 95% confidence interval [CI] 1.55-3.55, P < .001). The cohorts were similar in terms age, age of onset, limited vs diffuse cutaneous SSc, telangiectasias, gastroesophageal reflux disease, Raynaud phenomenon, serologies, interstitial lung disease, pulmonary arterial hypertension, scleroderma renal crisis, cancer prevalence, and overall mortality (all P > .05). However, for Native Americans, mortality specifically from fatal infections was 3.94-fold that of non-Natives (hazard ratio 6.88, 95% CI 1.37-34.64; P < .001). CONCLUSION In Native Americans of the American Southwest, SSc is increased in prevalence but is phenotypically similar to SSc in non-Natives. However, mortality due specifically to infection is increased in Native Americans with SSc.

Silva C, Solanki KK, White DH. The Relationship between Smoking, Raynaud's Phenomenon, Digital Ulcers, and Skin Thickness in the Waikato Systemic Sclerosis Cohort. RHEUMATOLOGY AND IMMUNOLOGY RESEARCH 2022; 3:84-89. [PMID: 36465326 PMCID: PMC9524819 DOI: 10.2478/rir-2022-0014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/17/2022] [Accepted: 05/09/2022] [Indexed: 06/17/2023]
Abstract
OBJECTIVES Systemic sclerosis (SSc) is a heterogeneous complex autoimmune connective tissue disease with variable presentation as a consequence of multisystem involvement. One of the key features of SSc is Raynaud's phenomenon along with vascular endothelial dysfunction that leads to digital ulcers (DUs). Raynaud's tends to be triggered by decreasing thermal gradient exposure, while stress and smoking also play a role. DUs arising as a consequence of severe Raynaud's and vasculopathy are a major cause of morbidity and disability in SSc. We set out to determine the relationship between smoking, Raynaud's phenomenon, DUs, and skin thickness in our Waikato Systemic Sclerosis cohort. METHODS The Waikato Systemic Sclerosis (SSc) database was used to extract data. Variables collected included demographics, age of diagnosis, SSc subtypes, age at first non-Raynaud's phenomenon, medications used for treatment of Raynaud's phenomenon or ulcers, and maximal modified Rodnan skin score (mRSS). Raynaud's phenomenon and finger DUs (severity for each over the past week and since diagnosis) and a Scleroderma Health Assessment Questionnaire (SHAQ) visual analog 10 cm scale were collected. The lead rheumatologist completed a physician's assessment of Raynaud's and the disease severity questionnaire. RESULTS Of the cohort of 143 patients, 100 patients were eligible to complete the questionnaires. Seventy-five patients returned completed questionnaires. Of these, the majority were female (88%), 52 (69.3%) had limited cutaneous systemic sclerosis (lcSSc), 17 (22.7%) had diffuse cutaneous systemic sclerosis (dcSSc), and 6 (8%) had an overlap syndrome. Thirty-six (48%) had a smoking history (in the time frame of collection of serial data). Mean ± standard deviation (SD) pack-years smoked were 17.11 ± 15.29 years. Thirty-five participants had a history of DUs, with a median of 4 DU (range 1-20). Of 17 patients with dcSSc, 12 (70.6%) had ulcers in comparison with 17 of 52 (32.7%) patients with lcSSc. There was a significant relationship between SSc subtype and the number with ulcers (X2 = 10.1, P = 0.007). There was also a significant relationship between physician severity of Raynaud's and presence of ulcers (t = 6.1, P < 0.001), which was not evident between patients' severity of Raynaud's and presence of ulcers (t = 1.9, P = 0.06). On the SHAQ score, smokers had significantly worse Raynaud's phenomenon over the prior week (t = 3.08, P = 0.03) and were more likely to note DUs over the preceding week, although the latter was not statistically significant (t = 1.95, P = 0.055). There was no association between smoking and skin thickness as measured by mRSS (r = 0.23, P = 0.19). CONCLUSION Our study demonstrates that smokers have had worse Raynaud's phenomenon over the past week and they were also more likely to note DUs with a trend toward significance but not statistically significant most likely due to our small sample size. Our study also demonstrated that patients with dcSSc had more ulcers in comparison with lcSSc. This study justifies physicians strongly recommending smoking cessation in patients with SSc.

Abstract
INTRODUCTION Systemic sclerosis (SSc) is a complex autoimmune disease with increased mortality, and interstitial lung disease (ILD) is a major cause of death. There are no recent epidemiological data on SSc and SSc-associated ILD (SSc-ILD) in Japan and little is known about how patients with these diseases are treated. METHODS The incidence rate and prevalence of SSc and SSc-ILD in Japan were estimated using the Japanese Medical Data Centre (JMDC) database. The demographic and clinical characteristics of patients and the immunomodulatory medications they received were also assessed using JMDC and the Medical Data Vision (MDV) databases. All analyses were descriptive. RESULTS The overall incidence rates of SSc and SSc-ILD per 100,000 person-years were 6.6 (95% confidence interval [CI] 6.2-7.1) and 1.9 (95% CI 1.6-2.1), respectively, and the overall prevalence per 100,000 persons was 37.0 (95% CI 35.6-38.5) and 13.9 (95% CI 13.0-14.8), respectively. ILD was the most common comorbidity in patients with SSc present in approximately 30% of patients (JMDC, 29.3%; MDV, 30.1%). The immunomodulatory medications prescribed were similar in patients with SSc and SSc-ILD, and each of the medications in this analysis was prescribed in less than 15% of patients. CONCLUSION We have demonstrated that estimates of prevalence and incidence rates of SSc and SSc-ILD in Japan are comparable to similar database studies conducted in the USA, using a medical claims database. Only a small proportion of patients were receiving immunomodulatory treatments, suggesting undertreatment in Japan.

Abstract
OBJECTIVES we aim to present an in-depth report of the incidence and prevalence of systemic sclerosis (SSc) in Sweden in a nation-wide register-based study covering the entire Swedish population METHODS: each individual residing in Sweden is given a unique personal identity number. We linked the National Patient Register and the Total Population Register to identify 1) patients with prevalent SSc on 2015-12-31 and 2) patients with incident SSc during the time period 2004-2015 based on ICD-10 codes. We estimated prevalence and incidence overall and stratified on age, sex, and county. RESULTS we identified 1774 prevalent cases, median age was 65 years (IQR 19.2) and 84% were women. The point prevalence estimate was 22.7 per 100,000 (95%CI 13.3-32.0). 1139 individuals were newly diagnosed with SSc during 2004-2015 with a median age of 60 years (IQR 20.6) and 80% were women. The mean standardized incidence was 11.9 per 1,000,000 person-years (95%CI 5.1-18.7). The annual incidence remained stable over the study period. Women had five times higher incidence and prevalence than men. The highest prevalence stratified by age strata was observed in the group aged 70-79. CONCLUSION SSc incidence and prevalence in Sweden are comparable to estimates from southern Europe, as opposed to the previous assumption of lower occurrence in northern Europe. We further observe that SSc incidence has been rather constant throughout recent years in Sweden with no obvious increase.

Abstract
Objective To investigate incidence and prevalence of Systemic Sclerosis (SSc) and association with interstitial lung disease (SSc-ILD) in a nationwide population-based study. Methods Patients with an incident diagnosis of SSc in 2000–2016 were identified in the Danish National Patient Registry and categorised based on diagnosis of ILD. Incidence- and prevalence proportions were calculated based on the annual population estimates. A cox proportional hazards model was used to evaluate the association between age, sex, region and marital status and presence of ILD. Results In total, 1869 patients with SSc were identified; 275 patients (14.7%) had SSc-ILD. The majority of patients were females (75.5%). The percentage of males was higher in SSc-ILD than in SSc alone (30.9% and 23.4%, p = 0.008). Median time from SSc to ILD diagnosis was 1.4 years (range 0–14.2). ILD was diagnosed from ≤4 years before to ≥7 years after SSc. Development of ILD was associated with male gender (HR 1.75, 95% CI 1.15–2.66), age 41–50 (HR 1.81, 95% CI 1.07–3.05) and residency in the North Denmark Region (HR 1.95, 9 5% CI 1.12–3.40). Mean annual incidence proportion of SSc was 2.9/100,000 and mean annual prevalence proportion was 16.8/100,000. The incidence remained stable, but prevalence proportion increased from 14.1 – 16.5/100,000 in 2000–2008 to 17.9–19.2/100,000 in 2009–2016. Conclusion The prevalence of SSc increased during the study period, while the incidence remained stable. The prevalence of SSc-ILD was 14.7% and thus less frequent than expected. Male sex and age between 41 and 50 years were associated with ILD.

Abstract
AIM Systemic sclerosis (SSc) is a rare, chronic autoimmune disease associated with a substantial economic burden. This study aimed to assess the costs associated with SSc and to identify major cost drivers. METHODS A systematic search was conducted in MEDLINE and Embase to identify relevant studies. Two independent reviewers evaluated studies based on inclusion/exclusion criteria and performed data extraction. Costs were converted into 2017 US dollars by purchasing power parity. The review was conducted following the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guideline. RESULTS The original literature search identified 113 potentially relevant citations, of which 10 articles met all the inclusion/exclusion criteria and were included in the data extraction and analysis. The identified studies evaluated costs associated with SSc in 11 countries from North America, Europe, and Australia published between 2009 and 2018. Eight studies reported direct costs and seven studies reported indirect costs. Direct costs varied from $3356 (Hungary) to $27 032 (Germany) with hospitalization and medication being two of the biggest components of direct medical costs in most studies. The indirect costs for lost productivity varied from $2433 (Italy) to $20 663 (UK), accounting for a significant portion of the total economic burden. CONCLUSIONS Large variations existed in annual costs of SSc, but all studies found that SSc imposed a substantial economic burden on patients and their families. The identified studies were mostly from high-income countries and there is still a knowledge gap regarding the cost of SSc in other parts of the world.

Abstract
Objective: Alexithymia is frequent in patients with some chronic dermatological conditions. The aim of the study was to measure the prevalence of alexithymia in patients with systemic sclerosis (SSc) using two different tools. Methods: Consecutive patients diagnosed with SSc were recruited at day hospital and hospitalization regimen. Alexithymia was measured using the self-administered questionnaire 20-item Toronto Alexithymia scale (TAS-20) and the semi-structured interview 24-item Toronto Structured Interview for Alexithymia (TSIA). Results: The study sample consisted of 67 female patients, aged from 29 to 82 years. According to TAS-20, 22.4% of patients were alexithymic and 17.9% were borderline alexithymic. Also, in our sample mean TAS-20 value was 48.9 and TSIA mean value was 20.3. Spearman's correlation coefficient between TAS-20 total score and TSIA total score was 0.603. A high correlation was observed between TAS total score and the "Affective Awareness" (AA) scale of the TSIA. TSIA total score significantly correlated with the "Difficulty describing feeling to others" (DDF) scale of the TAS-20. The highest correlation between scales of the two instruments was that between TAS-20 DDF and TSIA AA (r = 0.675). Conclusion: The prevalence of alexithymia in SSc patients was higher than in the general population, and similar to that of psoriasis patients. The measurements obtained using the TAS-20 and the TSIA were highly correlated. However, they also showed some diversities in the scales, indicating that they may measure different domains.

Abstract
Background: Scleroderma is a multisystem disease in which tissue fibrosis is caused by inflammation and vascular damage. The mortality of scleroderma has remained high due to a lack of effective treatments. However, exosomes derived from human umbilical cord mesenchymal stem cells (HUMSCs)-Ex have been regarded as potential treatments for various autoimmune diseases, and may also act as candidates for treating scleroderma. Methods: Mice with scleroderma received a single 50 μg HUMSCs-Ex. HUMSCs-Ex was characterized using transmission electron microscopy, nanoparticle tracking analysis and nanoflow cytometry. The therapeutic efficacy was assessed using histopathology, immunohistochemistry, immunofluorescence, quantitative real-time polymerase chain reaction, enzyme-linked immunosorbent assay and western blot. Results: HUMSCs-Ex ameliorated the deposition of extracellular matrix and suppressed the epithelial-mesenchymal transition process, and the effects lasted at least three weeks. In addition, HUMSCs-Ex promoted M1 macrophage polarization and inhibited M2 macrophage polarization, leading to the restoration of the balance of M1/M2 macrophages. Conclusion: We investigated the potential antifibrotic and anti-inflammatory effects of HUMSCs-Ex in a bleomycin-induced mouse model of scleroderma. So HUMSCs-Ex could be considered as a candidate therapy for scleroderma. Supplementary Information The online version contains supplementary material available at 10.1007/s13770-021-00405-5.

Abstract
BACKGROUND In immune-mediated inflammatory rheumatic diseases (IMIRD), there are differences between cis-men and cis-women in epidemiology, clinical feature, therapeutic approach, treatment response, and prognosis. In transgender individuals, information concerning IMIRD is not substantial. The assessment of information concerning rheumatic diseases in transgenders is crucial because transgenders may undergo treatments with potential impacts on IMIRD. We aim to collect and discuss current knowledge on IMIRD in transgender individuals, determine the coverage of the literature, identify the knowledge gaps, and highlight opportunities for future research. METHODS We did a scoping review of publications collected through a systematic search of transgender patients with any IMIRD. Data sources were Medline, Embase, and Web of Knowledge. Synthesis of results and qualitative review of data information was collected in tables. A semi-quantification of the quality of the articles reporting clinical studies was performed. RESULTS There were 11 transwoman, and 3 transmen cases of systemic lupus erythematosus (5 cases), skin lupus erythematosus (2), systemic sclerosis (4), anti-synthetase syndrome (1), rheumatoid arthritis (1) and ankylosing spondylitis (1). Eleven were de novo cases and three had prior history of IMIRD and developed a comorbidity after starting hormone replacement therapy. The clinical expression of the disease was variable. Two transwomen and one transman developed thrombotic events. The lupus skin lesions in one transman improved following testosterone treatment. No clinical studies were identified. Quality of publications was disparate. CONCLUSION Although the number of cases is small, most cases of IMIRD occur in transwomen. The absence of solid data warrants caution in establishing recommendations regarding hormone replacement therapy in transgenders with IMIRD. There is an essential need for the consideration of cisgender and transgender particularities in future research on IMIRD.

Abstract
OBJECTIVES Recent studies have proposed associations between systemic sclerosis (SSc) and atherosclerosis and between SSc and cardiovascular disease. However, in Asia, no large-scale studies have focused on the association between peripheral arterial disease (PAD) and SSc. SETTING A nationwide observation retrospective cohort study. PARTICIPANTS The National Health Insurance Research Database was used for selecting patients diagnosed with SSc from 2000 to 2011. Patients diagnosed with PAD before the index date were excluded. PRIMARY AND SECONDARY OUTCOME MEASURES The SSc cohort comprised 1106 patients with SSc, and the non-SSc cohort comprised 4424 matched controls. The Cox proportional hazards regression model was used for analysing the adjusted risk of PAD between the case and control patients. RESULTS The SSc cohort exhibited a significantly higher risk (HR=2.15, 95% CI=1.47 to 3.14) of PAD than did the non-SSc cohort. Patients with heart failure exhibited the highest risk of PAD (adjusted HR=2.10, 95% CI=1.20 to 3.70). Moreover, even without any comorbidities, the SSc cohort exhibited a significantly higher risk (adjusted HR=4.17 fold, 95% CI=1.98 to 8.77) of PAD than did the non-SSc cohort. CONCLUSION SSc is associated with a significantly high risk of PAD. Further studies are required to reduce the PAD risk among patients with SSc.

Abstract
BACKGROUND Pain is one of the most common symptoms affecting patients with systemic sclerosis; however, little is known about the relationship between self-efficacy and pain and changes in pain over time. OBJECTIVES The purpose of this study was to describe the relationships between self-efficacy and pain in patients with systemic sclerosis, as well as determine whether changes in self-efficacy mediate changes in pain. METHODS A prospective longitudinal study was conducted using data from the Scleroderma Patient-Centered Intervention Network Cohort. The baseline sample included 1,903 adults, with a trajectory subsample of 427 who completed 3-month assessments across 3 years. Hierarchical (sequential) forward multivariable regression, covarying for participant characteristics, was conducted to determine the association between self-efficacy and patient characteristics on pain outcomes. Trajectory models, covarying for participant characteristics, were used to examine changes in self-efficacy and pain outcomes across time and whether self-efficacy mediated the pain trajectories. RESULTS Mean time since diagnosis was 9.5 years, with 39.2% diagnosed with diffuse cutaneous systemic sclerosis. Greater self-efficacy was associated with less pain interference and intensity. Increasing age, female gender, finger ulcers, and small joint contractures were related to greater pain interference and intensity. Esophageal gastrointestinal symptoms were associated with more pain interference. Self-efficacy and pain trajectories remained stable across time, and self-efficacy did not mediate the pain trajectories. DISCUSSION This study identified self-efficacy, age, gender, finger ulcers, small joint contractures, and esophageal gastrointestinal symptoms as important correlates associated with pain in patients with systemic sclerosis. In addition, this study found that self-efficacy and pain outcomes remained stable over time, providing important insights into the longitudinal pain experiences of patients with systemic sclerosis.

Abstract
The increased awareness of systemic sclerosis (SS) and its pathogenetic background made the management of this disease more amenable than previously thought. However, scleroderma renal crisis (SRC) is a rarely seen as an associated disorder that may involve 2%-15% of SS patients. Patients presented with earlier, rapidly progressing, diffuse cutaneous SS disease, mostly in the first 3-5 years after non-Raynaud clinical manifestations, are more vulnerable to develop SRC. SRC comprises a collection of acute, mostly symptomatic rise in blood pressure, elevation in serum creatinine concentrations, oliguria and thrombotic microangiopathy in almost 50% of cases. The advent of the antihypertensive angiotensin converting enzyme inhibitors in 1980 was associated with significant improvement in SRC prognosis. In a scleroderma patient maintained on regular dialysis; every effort should be exerted to declare any possible evidence of renal recovery. A given period of almost two years has been suggested prior to proceeding in a kidney transplant (KTx). Of note, SS patients on dialysis have the highest opportunity of renal recovery and withdrawal from dialysis as compared to other causes of end-stage renal disease (ESRD). KTx that is the best well-known therapeutic option for ESRD patients can also be offered to SS patients. Compared to other primary renal diseases, SS-related ESRD was considered for a long period of poor patient and allograft survivals. Pulmonary involvement in an SS patient is considered a strong post-transplant independent risk factor of death. Recurrence of SRC after transplantation has been observed in some patients. However, an excellent post-transplant patient and graft outcome have been recently reported. Consequently, the absence of extrarenal manifestations in an SS-induced ESRD patient can be accepted as a robust indicator for a successful KTx.

Abstract
Interstitial lung disease (ILD) represents a significant cause of morbidity and mortality in systemic sclerosis (SSc). The purpose of this study was to examine recirculating lymphocytes from SSc patients for potential biomarkers of interstitial lung disease (ILD). Peripheral blood mononuclear cells (PBMCs) were isolated from patients with SSc and healthy controls enrolled in the Vanderbilt University Myositis and Scleroderma Treatment Initiative Center cohort between 9/2017–6/2019. Clinical phenotyping was performed by chart abstraction. Immunophenotyping was performed using both mass cytometry and fluorescence cytometry combined with t-distributed stochastic neighbor embedding analysis and traditional biaxial gating. This study included 34 patients with SSc-ILD, 14 patients without SSc-ILD, and 25 healthy controls. CD21lo/neg cells are significantly increased in SSc-ILD but not in SSc without ILD (15.4 ± 13.3% vs. 5.8 ± 0.9%, p = 0.002) or healthy controls (5.0 ± 0.5%, p < 0.0001). While CD21lo/neg B cells can be identified from a single biaxial gate, tSNE analysis reveals that the biaxial gate is comprised of multiple distinct subsets, all of which are increased in SSc-ILD. CD21lo/neg cells in both healthy controls and SSc-ILD are predominantly tBET positive and do not have intracellular CD21. Immunohistochemistry staining demonstrated that CD21lo/neg B cells diffusely infiltrate the lung parenchyma of an SSc-ILD patient. Additional work is needed to validate this biomarker in larger cohorts and longitudinal studies and to understand the role of these cells in SSc-ILD.

Abstract
The esophagus is the most commonly affected part of the gastrointestinal system in patients with systemic sclerosis (SSc). Esophageal involvement may lead to a significant reduction in patient quality of life. The exact pathophysiology is complex and not yet fully elucidated. Ultimately, esophageal smooth muscle becomes atrophied and replaced by fibrous tissue leading to severe motility disturbance of the distal esophagus. Symptoms are mainly attributed to gastroesophageal reflux disease and to esophageal dysmotility. Compelling evidence has correlated esophageal involvement to the severity of pulmonary disease. No formed guidelines exist about the diagnostic modalities used to assess esophageal disease in patients with SSc, though upper gastrointestinal endoscopy is the first and most important modality used as it can reveal alterations commonly observed in patients with SSc. Further exploration can be made by high resolution manometry and pH-impedance study. Proton pump inhibitors remain the mainstay of treatment, while prokinetic agents are commonly used as add-on therapy in patients with symptoms attributed to gastroesophageal reflux disease not responding to standard therapy as well as to motility disturbances. Gastroesophageal reflux disease symptoms in patients with SSc are frequently difficult to manage, and new therapeutic modalities are emerging. The role of surgical treatment is restricted and should only be preserved for resistant cases.

Abstract
OBJECTIVES We aimed to conduct a systematic review and meta-analysis on the incidence and prevalence of SSc covering the entire literature. METHODS This study followed the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement of 2009. We conducted a systematic search in MEDLINE, Web of Science and Embase to identify articles reporting incidence and/or prevalence of SSc. Two authors conducted the search, reviewed articles for inclusion and extracted relevant data. We used random-effects models to estimate the pooled prevalence and incidence of SSc and performed subgroup analyses by sex, case definition and region to investigate heterogeneity. We explored the association between calendar period and reported estimates using meta-regression. RESULTS Among 6983 unique records identified, we included 61 studies of prevalence and 39 studies of incidence in the systematic review. The overall pooled prevalence of SSc was 17.6 (95% CI 15.1, 20.5) per 100 000 and the overall pooled incidence rate of SSc was 1.4 (95% CI 1.1, 1.9) per 100 000 person-years. We observed significant regional variations in reported estimates; studies conducted in North America reported considerably higher estimates than other regions. The pooled incidence and prevalence in women were five times higher than in men. More recent studies reported higher estimates than older ones. CONCLUSION In this comprehensive review of the incidence and prevalence of SSc across the world, there was large heterogeneity among estimates, which should be taken into consideration when interpreting the results.

Abstract
Objective To identify the existence of a correlation among the various organs affected, focusing primarily on immuno-dermatological aspects, and to create a risk prediction model of organ-specific complications. Material and Methods Fifty-two patients with stable scleroderma, followed between 2015 and 2019, were investigated through an extensive multidisciplinary evaluation in the last year. Results Patients with lung involvement presented a worse degree of skin fibrosis than patients without it (p <0.001). No relationship was observed for the heart, kidney, and esophagus. Patients with pulmonary involvement had a lower pressure of the low esophagus sphincter and a higher Warrick score than patients without it (p <0.05). Age was significantly higher in patients with kidney involvement. Diffuse scleroderma patients had a worse pulmonary impairment than limited scleroderma patients (p <0.05). The manometric "sclerodermic" pattern was observed to be the most frequent (55.6%, p <0.05) in dcSSc patients while the sclerodermic and normal pattern were equally represented (41.2 and 32.4% respectively, p <0.05) in lcSSc patients. When compared to the negative serological groups, anti-Scl-70 positive patients presented a worse lung involvement while anti-centromere patients presented a better lung outcome (p <0.05). PM-Scl 100/75 positive patients presented mostly a pulmonary fibrotic pattern (p <0.05) and, also, heart complications were more likely associated with anti PM-Scl 100/75 positivity (p <0.05). The risk prediction model for organ-specific complications had an accuracy of 84.4% (95%CI 78, 89) in complication-site prediction, AUC of 0.871, 86% of sensitivity, and 83% of specificity, Cohen's Kappa (k) of 0.68. Conclusions Out of all the organs studied, the skin is the one that correlates with the lung. Patients with a diffuse form of disease presented more frequently the anti Scl-70 antibody and had a worse lung and esophageal involvement (scleroderma pattern) than the negative group. Conversely, patients with limited disease presented all positive for the anti-centromere antibody with a better lung involvement than the negative group, without any difference among the esophageal manometric pattern. Anti PM-Scl 100/75 antibody patients were associated with pulmonary fibrosis and presented cardiac involvement. The model created has demonstrated excellent values of sensitivity, specificity, and accuracy, but further studies are needed for validation.

Abstract
Systemic sclerosis is a rare multisystem autoimmune disorder that significantly impacts the orofacial region. Several oral features including microstomia and increased tooth loss contribute to the mouth-related disability. Prosthetic rehabilitation is very challenging in these patients. As the spectrum of dental implants indications has been recently extended to patients with various systemic disorders, the aim of this systematic review was to evaluate the outcome of dental implants in patients with systemic sclerosis. A literature search was conducted in Medline/PubMed database to identify eligible case-reports. 10 publications were included in qualitative synthesis. A total of 71 implants have been reported in 10 patients with systemic sclerosis with a mean of 7.1 +/- 3.8 implants per patient. Pre-implant surgeries have been described for 3 patients. Implant survival rates were higher than 98% but the mean follow-up time was only 28.3 +/- 18.6 months. Complications have been observed in 3 patients with 1 implant failure and peri-implant bone resorption in 2 patients. Although implant survival rates were high, an individualized assessment of risk-benefit balance is mandatory before indicating implant-based rehabilitation in patients suffering from systemic sclerosis and a scrupulous maintenance program has to be implemented. Further studies are strongly required to establish clinical guidelines.

Abstract
PURPOSE OF REVIEW As survival in systemic sclerosis (SSc) improves, research interest has shifted to the leading cause of non-SSc-related death, namely cancer, which accounts for over a third of non-SSc-related deaths. This review will provide an overview of the recent insights into the evolving relationship between SSc and cancer. RECENT FINDINGS Recent studies confirm the increased risk of cancer in SSc compared with the general population (standardized incidence ratio 1.9-2.2) in particular the risk of breast, lung and skin cancer. This increased cancer risk, particularly occurring in close proximity to SSc onset, raises the novel concept of autoimmunity occurring as a direct immune response to the cancerous cells. We highlight the important role that SSc-specific autoantibodies may have in identifying these at-risk patients, prognostication and triaging those who may require tight surveillance and further cancer screening. SUMMARY The knowledge will allow the development of future prospective studies evaluating clinically relevant and targeted cancer screening strategies for newly diagnosed SSc patients to optimize cancer detection while minimizing harms and costs from overscreening.

Abstract
Systemic sclerosis is a rare and incurable autoimmune disease in which patients are challenged with self-managing their disease. Systematic evaluation of the essential self-management intervention components and self-management outcomes is necessary to assess the state of the science of self-management for patients with systemic sclerosis. As such, the purpose of this systematic review was to identify and describe self-management interventions and their impact on self-management outcomes in adults with systemic sclerosis. Studies were included if they contained a self-management intervention, incorporated at least one self-management outcome identified as a common data element by the National Institute of Nursing Research (i.e., patient activation, self-efficacy, self-regulation, global health), and were conducted in adults with systemic sclerosis. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, PubMed, Cumulative Index of Nursing and Allied Health Literature, and Embase were searched from the inception of each database to March 2020, yielding a total of 215 studies. Of these reports, 16 met the inclusion criteria for this review. There was notable variability in the types of self-management interventions and their effects on key self-management outcomes. Self-management interventions focused on improving physical function through rehabilitation programs were the most common interventions (n = 7). The poor methodological quality of the studies included in this systematic review, however, limited the synthesis of and recommendations for self-management interventions in adults with systemic sclerosis. Future research in systemic sclerosis should include key self-management outcomes in larger, more rigorously designed studies to allow for comparisons across studies and to advance the science of self-management.

Methods and Results Health outcomes and costs were captured through data linkage. Health utility was derived from Medical Outcomes Study Short Form‐36 scores. A probabilistic discrete‐time model was developed to simulate lifetime changes in costs and health utility. Mortality was predicted using a Gompertz parametric survival model. For both treatment arms, the simulations were started using the same cohort of 10 000 patients. Probabilistic sensitivity analysis was performed using the Monte Carlo simulation with 1000 sets of sampled parameter values. Of 143 patients with systemic sclerosis–related pulmonary arterial hypertension, 89 were on monotherapy and 54 on combination therapy. Mean simulated costs per patient per year in monotherapy and combination therapy groups were AU$23 411 (US$16 080) and AU$29 129 (US$19 982), respectively. Mean life years and quality‐adjusted life years from pulmonary arterial hypertension diagnosis to death of patients receiving monotherapy were 7.1 and 3.0, respectively, and of those receiving combination therapy were 9.2 and 3.9, respectively. Incremental costs per life year and quality‐adjusted life year gained of combination therapy compared with monotherapy were AU$47 989 (US$32 920) and AU$113 823 (US$78 082), respectively. At a willingness‐to‐pay threshold of AU$102 000 (US$69 972) per life year gained, and of AU$177 222 (US$121 574) per quality‐adjusted life year gained, the probability of combination therapy being cost‐effective was 0.95. Conclusions The incremental cost per quality‐adjusted life year gained of combination therapy compared with monotherapy was substantial in the base case analysis. Given the fatal prognosis of systemic sclerosis–related pulmonary arterial hypertension and the incremental cost per life year of AU$47 989 (US$32 920), combination therapy could be considered cost‐effective in systemic sclerosis–related pulmonary arterial hypertension.

Abstract
OBJECTIVE To quantify the burden of cancer in systemic sclerosis (SSc). METHODS Standardized incidence ratios (SIRs) and standardized mortality ratios relative to the general Australian population were derived. Cox proportional hazards regression was used to estimate survival in patients with SSc with cancer compared to patients without. Determinants of cancer were identified using logistic regression. Health care cost was quantified through cross-jurisdictional data linkage. RESULTS This SSc cohort of 1,727 had a cancer incidence of 1.3% per year and a prevalence of 14.2%, with a SIR of 2.15 (95% confidence interval [95% CI] 1.84-2.49). The most common cancers were breast, melanoma, hematologic, and lung. Anti-RNA polymerase III (RNAP) antibody was associated with an increased risk of cancer (odds ratio [OR] 2.9, P = 0.044), diagnosed within 5 years of SSc disease onset. Calcium channel blockers were associated with a higher risk of overall cancer (OR 1.47, P = 0.016), breast cancer (OR 1.61, P = 0.051), and melanoma (OR 2.01, P = 0.042). Interstitial lung disease (ILD) was associated with lung cancer (OR 2.83, P = 0.031). Incident SSc cancer patients had >2-fold increased mortality compared to patients with SSc without cancer (hazard ratio 2.85 [95% CI 1.51-5.37], P = 0.001). Patients with SSc and cancer utilized more health care than those without cancer, with an excess annual health care cost of $1,496 Australian (P < 0.001). CONCLUSION SSc carries an increased risk of developing cancer, particularly lung cancer associated with ILD, and breast cancer and melanoma occurring close to SSc disease onset in association with RNAP antibodies. Compared to those patients without cancer, patients with SSc and cancer had higher mortality and an increased health care cost, with an annual excess per patient cost of $1,496 Australian (P < 0.001).
