Abstract
There are notable sex-based differences in immune responses to pathogens and self-antigens, with female individuals exhibiting increased susceptibility to various autoimmune diseases, and male individuals displaying preferential susceptibility to some viral, bacterial, parasitic and fungal infections. Although sex hormones clearly contribute to sex differences in immune cell composition and function, the presence of two X chromosomes in female individuals suggests that differential gene expression of numerous X chromosome-linked immune-related genes may also influence sex-biased innate and adaptive immune cell function in health and disease. Here, we review the sex differences in immune system composition and function, examining how hormones and genetics influence the immune system. We focus on the genetic and epigenetic contributions responsible for altered X chromosome-linked gene expression, and how this impacts sex-biased immune responses in the context of pathogen infection and systemic autoimmunity.

Abstract
The heterogeneity of atypical wounds can present diagnostic and therapeutic challenges; however, as the prevalence of atypical wounds grows worldwide, prompt and accurate management is increasingly an essential skill for dermatologists. Addressing the underlying cause of an atypical wound is critical for successful outcomes. An integrated approach with a focus on pain management and patient engagement is recommended to facilitate enduring wound closure. Advances in treatment, in addition to further research and clinical training, are necessary to address the expanding burden of atypical wounds.

The Role of Sex and Gender in Dermatology - From Pathogenesis to Clinical Implications. J Cutan Med Surg 2023; 27:NP1-NP36. [PMID: 37401812 PMCID: PMC10486181 DOI: 10.1177/12034754231177582] [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: 01/05/2023] [Revised: 03/29/2023] [Accepted: 04/09/2023] [Indexed: 07/05/2023]
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
Objective To compare organ involvement and disease severity between male and female patients with juvenile onset systemic sclerosis. Methods Demographics, organ involvement, laboratory evaluation, patient-reported outcomes and physician assessment variables were compared between male and female juvenile onset systemic sclerosis patients enrolled in the prospective international juvenile systemic sclerosis cohort at their baseline visit and after 12 months. Results One hundred and seventy-five juvenile onset systemic sclerosis patients were evaluated, 142 females and 33 males. Race, age of onset, disease duration, and disease subtypes (70% diffuse cutaneous) were similar between males and females. Active digital ulceration, very low body mass index, and tendon friction rubs were significantly more frequent in males. Physician global assessment of disease severity and digital ulcer activity was significantly higher in males. Composite pulmonary involvement was also more frequent in males, though not statistically significantly. After 12 months, they are the pattern of differences changed female patients had significantly more frequent pulmonary involvement. Conclusion In this cohort, juvenile onset systemic sclerosis had a more severe course in males at baseline and but the pattern changed after 12 months. Some differences from adult findings persisted, there is no increased signal of pulmonary arterial hypertension or heart failure in male pediatric patients. While monitoring protocols of organ involvement in juvenile onset systemic sclerosis need to be identical for males and females.

Protein biomarkers of disease progression in patients with systemic sclerosis associated interstitial lung disease. Sci Rep 2023; 13:8645.

Abstract
Systemic sclerosis is a rare connective tissue disease; and interstitial lung disease (SSc-ILD) is associated with significant morbidity and mortality. There are no clinical, radiologic features, nor biomarkers that identify the specific time when patients are at risk for progression at which the benefits from treatment outweigh the risks. Our study aimed to identify blood protein biomarkers associated with progression of interstitial lung disease in patients with SSc-ILD using an unbiased, high-throughput approach. We classified SSc-ILD as progressive or stable based on change in forced vital capacity over 12 months or less. We profiled serum proteins by quantitative mass spectrometry and analyzed the association between protein levels and progression of SSc-ILD via logistic regression. The proteins associated with at a p value of < 0.1 were queried in the ingenuity pathway analysis (IPA) software to identify interaction networks, signaling, and metabolic pathways. Through principal component analysis, the relationship between the top 10 principal components and progression was evaluated. Unsupervised hierarchical clustering with heatmapping was done to define unique groups. The cohort consisted of 72 patients, 32 with progressive SSc-ILD and 40 with stable disease with similar baseline characteristics. Of a total of 794 proteins, 29 were associated with disease progression. After adjusting for multiple testing, these associations did not remain significant. IPA identified five upstream regulators that targeted proteins associated with progression, as well as a canonical pathway with a higher signal in the progression group. Principal component analysis showed that the ten components with the highest Eigenvalues represented 41% of the variability of the sample. Unsupervised clustering analysis revealed no significant heterogeneity between the subjects. We identified 29 proteins associated with progressive SSc-ILD. While these associations did not remain significant after accounting for multiple testing, some of these proteins are part of pathways relevant to autoimmunity and fibrogenesis. Limitations included a small sample size and a proportion of immunosuppressant use in the cohort, which could have altered the expression of inflammatory and immunologic proteins. Future directions include a targeted evaluation of these proteins in another SSc-ILD cohort or application of this study design to a treatment naïve population.

Abstract
Systemic sclerosis is a systemic autoimmune rheumatic disease characterized by immune abnormalities, leading to vasculopathy and fibrosis. Autoantibody testing has become an increasingly important part of diagnosis and prognostication. Clinicians have been limited to antinuclear antibody (ANA), antitopoisomerase I (also known as anti-Scl-70) antibody, and anticentromere antibody testing. Many clinicians now have improved access to an expanded profile of autoantibody testing. In this narrative review article, we review the epidemiology, clinical associations, and prognostic value of advanced autoantibody testing in people with systemic sclerosis.

Abstract
Objective Male sex and black race incur poor prognosis in systemic sclerosis (SSc). There is no nationwide population-based assessment of premature SSc death burden by sex and race. Methods This is a population-based study comprising all recorded SSc deaths across the United States. We constructed histograms depicting the number of SSc deaths for each age by sex and race, and calculated the cumulative percent death at each age and the median age of death. We determined the odds ratios for the risk of premature death from SSc by sex and race. We then calculated the percent of total SSc deaths for different age groups by sex and race from 1970 to 2015. We performed chi-square test with Yates's correction and quantified the odds ratio (OR) with 95% confidence interval (CI). Results The median age of SSc death was 63 years in males versus 68 years in females, and 57 years in blacks versus 70 years in whites. The odds for SSc death before 65 years age was 1.8 (95% CI, 1.6-2.0) for males compared with females and 5.1 (95% CI, 4.4-6.0) for blacks compared with whites. The higher odds for premature death in males than in females was similar for both races. Differences in the proportions of premature deaths from 1970 to 2015 increased between males and females (-5% to 17%) and between blacks and whites (14% to 36%). Conclusion Males and black persons die of SSc at younger ages. The worsening premature death burden gap between the two sexes and races over the last five decades is troublesome.

Abstract
INTRODUCTION Calcinosis is common in patients with systemic sclerosis (SSc) and refers to the sub-epidermal deposition of calcium salts in the skin. SSc-related calcinosis is associated with significant morbidity, including through cutaneous ulceration and predisposition to become infected. AREAS COVERED After briefly addressing aetiopathogenesis, we describe the clinical burden of SSc-associated calcinosis and provide a structured and practical clinical approach to diagnosis and assessment, including discussion of the role of different imaging modalities. The multi-faceted treatment of SSc-associated calcinosis is presented under three broad headings of 'general measures,' and 'medical treatment' and 'surgical treatment.' We adopted a narrative approach to identify relevant manuscripts to inform our review. EXPERT OPINION SSc-related calcinosis is an area of major unmet clinical need and for too long has been a neglected area of research. Safe and effective treatments are badly needed to improve patient quality of life and outcomes. To facilitate future clinical trials, we require increased understanding of pathogenesis (to inform selection of potential targeted therapies) and reliable outcome measures, including those which will measure the impact and severity of calcinosis from the patient perspective. International collaborative research is ongoing to develop outcome measures and treatments for this potentially devastating complication of SSc.

Abstract
OBJECTIVES The cytokine oncostatin M (OSM) is implicated in the pathology of SSc. Inhibiting OSM signalling using GSK2330811 (an anti-OSM monoclonal antibody) in patients with SSc has the potential to slow or stop the disease process. METHODS This multicentre, randomized, double-blind, placebo-controlled study enrolled participants ≥18 years of age with active dcSSc. Participants were randomized 3:1 (GSK2330811:placebo) in one of two sequential cohorts to receive GSK2330811 (cohort 1: 100 mg; cohort 2: 300 mg) or placebo s.c. every other week for 12 weeks. The primary endpoint was safety; blood and skin biopsy samples were collected to explore mechanistic effects on inflammation and fibrosis. Clinical efficacy was an exploratory endpoint. RESULTS Thirty-five participants were randomized to placebo (n = 8), GSK2330811 100 mg (n = 3) or GSK2330811 300 mg (n = 24). Proof of mechanism, measured by coordinate effects on biomarkers of inflammation or fibrosis, was not demonstrated following GSK2330811 treatment. There were no meaningful differences between GSK2330811 and placebo for any efficacy endpoints. The safety and tolerability of GSK2330811 were not favourable in the 300 mg group, with on-target, dose-dependent adverse events related to decreases in haemoglobin and platelet count that were not observed in the 100 mg or placebo groups. CONCLUSION Despite a robust and novel experimental medicine approach and evidence of target engagement, anticipated SSc-related biologic effects of GSK2330811 were not different from placebo and safety was unfavourable, suggesting OSM inhibition may not be a useful therapeutic strategy in SSc.

Abstract
Objectives The objectives of this study were to describe the impact of systemic sclerosis associated interstitial lung disease, on quality of life, to estimate the correlation between quality of life and severity of lung disease and to assess the impact of interstitial lung disease on caregivers. Methods Seven investigators included systemic sclerosis associated interstitial lung disease patients from December 2019 to April 2020. Sociodemographics and clinical data were collected. Patients reported outcomes and questionnaires were used with 1 generic patients reported outcome (EQ-5D-5L), 1 specific PRO (Brief Interstitial Lung Disease) and 2 self-reported questionnaires on impact of SSc complications and impact on caregivers. The correlation between forced vital capacity and EQ-5D-5L score was estimated with a multivariate linear regression model adjusted on several covariates. Results In all, 89 patients were included. 26.4% were males, mean age was 58.2 ± 14.5 years. Mean EQ-5D-5L score = 0.79 ± 0.22 (median = 0.85). Mean EQ-5D-5L visual analog scale score = 60.8 ± 20.4 (median = 61.5). Mean King's Brief Interstitial Lung Disease score = 58.4 ± 12.7 (median = 58.0). After adjustment on covariates, a significant correlation between forced vital capacity and EQ-5D-5L score was found with an increase of 0.003 of the EQ-5D-5L score for a 1% increase of FVC (p = 0.0096). No significant correlation between forced vital capacity and the EQ-VAS and King's Brief Interstitial Lung Disease score were found. The impact of SSc on other organs was significantly correlated with EQ- 5D-5L score, respectively, for the impact scores on the lung system (p = 0.0003), heart system (p = 0.0182), Raynaud's syndrome (p = 0.0015), digestive system (p = 0.0032), joints/muscles (p = 0.0003), skin (p < 0.0001), kidney (p = 0.0052) and gastro-oesophageal reflux (p = 0.0063). Significant correlations between King's Brief Interstitial Lung Disease score and lung system (p < 0.0001), heart system (p < 0.0001), digital ulcers (p = 0.058), digestive system (p < 0.0001), kidney (p = 0.0004), skin (p = 0.0499) and gastro-oesophageal reflux (p = 0.0033) scores were found 68.5% of patients reported their need for a caregiver to help them in their daily life activities. Conclusion Our study highlighted the strong burden of systemic sclerosis associated interstitial lung disease` for patients, especially with an impact on quality of life, on other organs manifestations and need for caregivers in their daily life.

Abstract
Interstitial lung disease (ILD) has been recognized as a frequent manifestation associated with a substantial morbidity and mortality burden in patients with autoimmune rheumatic disorders. Serum autoantibodies are considered good biomarkers for identifying several subsets or specific phenotypes of ILD involvement in these patients. This review features the role of several autoantibodies as a diagnostic and prognostic biomarker linked to the presence ILD and specific ILD phenotypes in autoimmune rheumatic disorders. The case of the diverse antisynthetase antibodies in the antisynthease syndrome or the anti-melanoma differentiation-associated 5 protein (MDA5) antibodies as a marker of a severe condition such as rapidly progressive ILD in patients with clinically amyopathic dermatomyositis are some of the associations herein reported in the group of myositis spectrum disorders. Specific autoantibodies such as the well-known anti-topoisomerase I (anti-Scl70) or the anti-Th/To, anti-U11/U12 ribonucleoprotein, and anti-eukaryotic initiation factor 2B (eIF2B) antibodies seems to be specifically linked to ILD in patients with systemic sclerosis. Overlap syndromes between systemic sclerosis and myositis, also have good ILD biomarkers, which are the anti-PM/Scl and anti-Ku autoantibodies. Lastly, other not so often reported disorders as being associated with ILD but recently most recognized as is the case of rheumatoid arthritis associated ILD or entities herein included in the miscellaneous disorders section, which include anti-neutrophil cytoplasmic antibody-associated interstitial lung disease, Sjögren's syndrome or the mixed connective tissue disease, are also discussed.

Abstract
OBJECTIVE The epidemiology and treatment of peripheral neuropathy in systemic sclerosis (SSc) is poorly understood. The objectives of this study were to evaluate the incidence, prevalence, risk factors, and treatments of peripheral neuropathy in SSc. METHODS A systematic review of Medline, Embase and CINAHL databases for literature reporting peripheral neuropathy in SSc was performed. Studies evaluating incidence, prevalence, risk factors, and treatments were synthesized. Meta-analysis using a random effects model was used to evaluate the prevalence of peripheral neuropathy. RESULTS 113 studies reported 949 subjects with at least one type of peripheral neuropathy out of 2143 SSc patients studied. The mean age was 48.5 years. The mean time between SSc onset and detection of peripheral neuropathy was 8.85 years. The pooled prevalence of neuropathy was 27.4% (95%CI 22.4% - 32.7%). Risk factors for peripheral neuropathy in SSc included advanced diffuse disease, anticentromere antibodies, calcinosis cutis, ischemia of the vasa nervosum, iron deficiency anemia, metoclopramide, pembrolizumab, silicosis and uremia. There were 73 subjects with successful treatments (n=36 restoring sensation, n=37 restoring motor or sensorimotor function). Treatments included decompression surgery, prednisone, cyclophosphamide, carbamazepine, transcutaneous electrical nerve stimulation, tricyclic antidepressants and IVIG. CONCLUSION All-cause peripheral neuropathy is not uncommon in SSc. Compression neuropathies can be treated with decompression surgery. Observational data reporting immunosuppressive and anticonvulsants to treat peripheral neuropathy in SSc is limited and conflicting. This data provides the signal of effect to justify RCT to evaluate the efficacy of these interventions.

Abstract
Raynaud's phenomenon (RP) is common in rheumatic diseases. In the setting of systemic sclerosis (SSc), it can be complicated by digital ischemia that includes ulceration and gangrene. Systemic adverse effects may preclude the use of oral or topical vasodilators for the treatment of RP and its complications. In this article, we review effectiveness/efficacy of botulinum toxin injection in primary and secondary RP. We discuss botulinum toxin formulations, dosage, sites of administration, and adverse effects. The evidence for botulinum toxin in the treatment of primary and SSc-associated RP is promising. Consistency across patient populations, treatment options (botulinum serotype, dose, and injection site), and outcome measures will be essential for further research.

Abstract
Introduction: Limited cutaneous systemic sclerosis with special manifestations (calcinosis cutis, Raynaud’s phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia) is part of the group of connective tissue diseases, these rare autoimmune systemic pathologies cause thickening and hardening of tissues in different parts of the body and can lead to complex disorders. Oral manifestations of systemic sclerosis may include limited ability to open the mouth, xerostomia, periodontal disease, enlarged periodontal ligament, and bone resorption of the jaw. Case Description: A 54-year-old Caucasian patient presented with oral pain, swallowing, phonation and chewing difficulties associated with dental instability, hygiene/handling difficulties and her main problem with microstomia, which prevented her from removing the skeletal prosthesis for 4 years, depriving her of social life. Gradual treatment with dental implants was diagnosed and planned to support a fixed total denture adapted to the ridge with self-cleaning characteristics. After implant insertion, panoramic radiographs with standardized parameters were taken to compare crestal bone levels at the time of prosthesis placement and with 10 years of follow-up. Conclusion: The average crestal bone loss of the 12 implants after the 10 years of follow-up was 1.26 mm for the maxilla and 1.17 mm for the mandible. The survival of the 12 support implants of two total fixed prostheses in a clinical/radiographic follow-up of 10 years was 100%. After 10 years of follow-up, the 12 implants inserted had a bone loss similar to that of healthy patients and no pathologies were registered, recovering function, aesthetics, and self-esteem. This therapy must be implemented before the interincisal distance decreases to 30 mm to allow intraoral surgical/prosthetic access. Implant-supported total fixed rehabilitation is a viable, predictable, and recommended therapy in patients with limited cutaneous systemic sclerosis.

Abstract
BACKGROUND Both TGFβ and estradiol (E2), a form of estrogen, are pro-fibrotic in the skin. In the connective tissue disease, systemic sclerosis (SSc), both TGFβ and E2 are likely pathogenic. Yet the regulation of TGFβ in E2-induced dermal fibrosis remains ill-defined. Elucidating those regulatory mechanisms will improve the understanding of fibrotic disease pathogenesis and set the stage for developing potential therapeutics. Using E2-stimulated primary human dermal fibroblasts in vitro and human skin tissue ex vivo, we identified the important regulatory proteins for TGFβ and investigated the extracellular matrix (ECM) components that are directly stimulated by E2-induced TGFβ signaling. METHODS We used primary human dermal fibroblasts in vitro and human skin tissue ex vivo stimulated with E2 or vehicle (ethanol) to measure TGFβ1 and TGFβ2 levels using quantitative PCR (qPCR). To identify the necessary cell signaling proteins in E2-induced TGFβ1 and TGFβ2 transcription, human dermal fibroblasts were pre-treated with an inhibitor of the extracellular signal-regulated kinase/mitogen-activated protein kinase (ERK/MAPK) pathway, U0126. Finally, human skin tissue ex vivo was pre-treated with SB-431542, a TGFβ receptor inhibitor, and ICI 182,780, an estrogen receptor α (ERα) inhibitor, to establish the effects of TGFβ and ERα signaling on E2-induced collagen 22A1 (Col22A1) transcription. RESULTS We found that expression of TGFβ1, TGFβ2, and Col22A1, a TGFβ-responsive gene, is induced in response to E2 stimulation. Mechanistically, Col22A1 induction was blocked by SB-431542 and ICI 182,780 despite E2 stimulation. Additionally, inhibiting E2-induced ERK/MAPK activation and early growth response 1 (EGR1) transcription prevents the E2-induced increase in TGFβ1 and TGFβ2 transcription and translation. CONCLUSIONS We conclude that E2-induced dermal fibrosis occurs in part through induction of TGFβ1, 2, and Col22A1, which is regulated through EGR1 and the MAPK pathway. Thus, blocking estrogen signaling and/or production may be a novel therapeutic option in pro-fibrotic diseases.

Abstract
OBJECTIVES Systemic sclerosis (SSc) is an autoimmune disease with incompletely revealed etiology and pathophysiology. There are still no specific and reliable biomarkers. Here we examined YKL-40 as a biomarker of inflammation and fibrosis, and suggest a possible mechanism for its regulation. METHODS Forty female patients with SSc (26 with diffuse cutaneous (dcSSc) and 14 with limited cutaneous SSc (lcSSc)) and 14 healthy female controls were enrolled in this cross-sectional study. Bioinformatic tools identified miR-214 binding site in the 3'-untranslated region (3'UTR) of YKL-40 mRNA. Serum levels of YKL-40 were examined by ELISA, while YKL-40 mRNA and miR-214 was measured by qPCR. RESULTS The in silico analysis revealed several microRNAs (miRNAs) targeting YKL-40 mRNA, from which miR-214 was selected. YKL-40 serum levels were significantly higher in patients compared to controls (p = .0042). In contrary, miR-214 expression in plasma of SSc patients was significantly down-regulated compared to controls (p = .0058). Receiver operating characteristic (ROC) and area under the curve (AUC) analysis showed that both serum YKL-40 and plasma miR-214 levels had good capacity to distinguish patients with SSc, dcSSc and lcSSc from healthy subjects. CONCLUSION YKL-40 and miR-214 have different expression profile in SSc. Increased serum levels of YKL-40 could be associated with down-regulation of miR-214 expression in plasma. Both, YKL-40 concentrations and miR-214 plasma fold change values might serve as possible biomarkers in SSc.

Abstract
Systemic sclerosis is a complex, often progressive, multisystem autoimmune disease. It is commonly categorized into limited cutaneous or diffuse cutaneous systemic sclerosis. There is near universal involvement of skin fibrosis and gastrointestinal dysfunction, but lung disease is not only common but also a most serious complication. Severe lung disease is the top cause of mortality, displacing scleroderma renal crisis as the leading cause of death. Whether there is limited cutaneous or diffuse cutaneous manifestations can be predictive of what type of lung disease that can present in the patient. Limited cutaneous systemic sclerosis patients tend to have pulmonary hypertension whereas diffuse cutaneous systemic sclerosis patients tend to have interstitial lung disease. There are more rare phenotypes associated with antibodies Th/To and U3RNP that can have both pulmonary hypertension and interstitial lung disease concomitantly. There are inherent challenges in the management for both pulmonary hypertension and interstitial lung disease but with the focus on early diagnosis for each of these lung complications, treatment may have a higher chance of efficacy.

Abstract
INTRODUCTION Systemic sclerosis (SSc) is a multi-dimensional connective tissue disease of unknown etiology. Given the immense clinical complexity of SSc, the treatment of this condition is not standardized and considerable heterogeneity exists in SSc management approaches. The purpose of this article is to highlight novel therapeutic strategies and new medications under development for the treatment of systemic sclerosis (SSc). AREAS COVERED Herein, the authors focus primarily on recently completed clinical trials and phase 3 and 4 clinical trials of therapeutic agents that show promise in SSc. This review is organized by the clinical complications that occur in SSc, for which novel treatment strategies are under study. EXPERT OPINION Combining therapies to address the individual manifestations of SSc is a cornerstone to the comprehensive management of this condition. Therapeutic strategies must take into account the organs involved, the level of disease activity in each area, and the disease stage. Controlling the complex biological network, progressive vasculopathy and fibrosis, as well as manifestations of end-organ dysfunction are all critical considerations when determining the best treatment approach for SSc.

Abstract
There have been many recent trials in systemic sclerosis (SSc) that have explored treatment for skin or lung. Some have been encouraging, but there has also been disappointment reflecting potential limitations of treatment effect of study design. These trials are discussed and reviewed. Studies conducted in SSc are described and discussed with a focus on endpoint selection and trial design as well as potential mechanism of action and treatment effect. Studies have included very encouraging trials of interleukin 6 blockade, immunosuppression, and broad-spectrum tyrosine kinase inhibition. Other trials including recent studies of peroxisome proliferator-activated receptor agonists and specific intracellular signaling inhibitors such as imatinib or anti-transforming growth factor beta blocking strategies have been more disappointing. Trial design is improving, and overall, there are now almost positive trials using agents with great promise, and studies are also providing important biological insight into SSc. It is hoped that ongoing studies will further progress the field and move it toward better treatments for SSc that still represent a major unmet medical need.

Abstract
Systemic sclerosis (SSc) is a heterogeneous disease with variability in autoantibody profiles, skin and internal organ involvement, disease trajectory, and survival. The ability to identify more homogeneous subsets of SSc patients has informed patient care and been an essential aspect of SSc research. In this article, the historic evolution of subsetting systems in SSc are described including clinically based SSc subsetting systems, their utility, strengths, and limitations. There is a shifting paradigm of SSc subsets, including biologic classification of SSc subsets and fully data-driven approaches to SSc subset classification, taking into consideration the needs of the SSc global community in the modern era and the ability to prognosticate patients with SSc.

The contribution of epigenetics to the pathogenesis and gender dimorphism of systemic sclerosis: a comprehensive overview. Ther Adv Musculoskelet Dis 2020; 12:1759720X20918456.

Abstract
Systemic sclerosis (SSc) is a life-threatening connective tissue disorder of unknown etiology characterized by widespread vascular injury and dysfunction, impaired angiogenesis, immune dysregulation and progressive fibrosis of the skin and internal organs. Over the past few years, a new trend of investigations is increasingly reporting aberrant epigenetic modifications in genes related to the pathogenesis of SSc, suggesting that, besides genetics, epigenetics may play a pivotal role in disease development and clinical manifestations. Like many other autoimmune diseases, SSc presents a striking female predominance, and even if the reason for this gender imbalance has yet to be completely understood, it appears that the X chromosome, which contains many gender and immune-related genes, could play a role in such gender-biased prevalence. Besides a short summary of the genetic background of SSc, in this review we provide a comprehensive overview of the most recent insights into the epigenetic modifications which underlie the pathophysiology of SSc. A particular focus is given to genetic variations in genes located on the X chromosome as well as to the main X-linked epigenetic modifications that can influence SSc susceptibility and clinical phenotype. On the basis of the most recent advances, there is realistic hope that integrating epigenetic data with genomic, transcriptomic, proteomic and metabolomic analyses may provide in the future a better picture of their functional implications in SSc, paving the right way for a better understanding of disease pathogenesis and the development of innovative therapeutic approaches.

Abstract
Systemic sclerosis (SSc) is an autoimmune fibrotic disease of unknown aetiology that is characterized by vascular changes in the skin and visceral organs. Autologous haematopoietic stem cell transplantation can improve skin and organ fibrosis in patients with progressive disease and a high risk of organ failure, indicating that cells originating in the bone marrow are important contributors to the pathogenesis of SSc. Animal studies also indicate a pivotal function of myeloid cells in the development of fibrosis leading to changes in the tissue architecture and dysfunction in multiple organs such as the heart, lungs, liver and kidney. In this Review, we summarize current knowledge about the function of myeloid cells in fibrogenesis that occurs in patients with SSc. Targeted therapies currently in clinical studies for SSc might affect myeloid cell-related pathways. Therefore, myeloid cells might be used as cellular biomarkers of disease through the application of high-dimensional techniques such as mass cytometry and single-cell RNA sequencing.

Abstract
OBJECTIVES Mortality and worsening of organ function are desirable endpoints for clinical trials in systemic sclerosis (SSc). The aim of this study was to identify factors that allow enrichment of patients with these endpoints, in a population of patients from the European Scleroderma Trials and Research group database. METHODS Inclusion criteria were diagnosis of diffuse SSc and follow-up over 12±3 months. Disease worsening/organ progression was fulfilled if any of the following events occurred: new renal crisis; decrease of lung or heart function; new echocardiography-suspected pulmonary hypertension or death. In total, 42 clinical parameters were chosen as predictors for the analysis by using (1) imputation of missing data on the basis of multivariate imputation and (2) least absolute shrinkage and selection operator regression. RESULTS Of 1451 patients meeting the inclusion criteria, 706 had complete data on outcome parameters and were included in the analysis. Of the 42 outcome predictors, eight remained in the final regression model. There was substantial evidence for a strong association between disease progression and age, active digital ulcer (DU), lung fibrosis, muscle weakness and elevated C-reactive protein (CRP) level. Active DU, CRP elevation, lung fibrosis and muscle weakness were also associated with a significantly shorter time to disease progression. A bootstrap validation step with 10 000 repetitions successfully validated the model. CONCLUSIONS The use of the predictive factors presented here could enable cohort enrichment with patients at risk for overall disease worsening in SSc clinical trials.

Abstract
BACKGROUND Systemic sclerosis (SSc) is a female-predominant disease, characterized by excessive extracellular matrix deposition (ECM) with dermal and internal organ fibrosis. Considering the sex-based disparity in disease incidence, estradiol (E2), an estrogen form with pro-fibrotic effects, may play a role in SSc. We reported that post-menopausal women with diffuse cutaneous (dc)SSc have higher serum E2 levels compared to similar aged, healthy controls. Since males with SSc tend to have more severe disease, we examined serum E2 in dcSSc males in relation to disease characteristics and survival. METHODS We measured serum E2 in 83 dcSSc men > 50 years old from the University of Pittsburgh Scleroderma Center and similar aged healthy controls. Using statistical modeling, we examined the associations between serum E2, internal organ involvement, autoantibody profiles, and survival. RESULTS Male dcSSc patients had significantly higher serum E2 levels compared to healthy males and similar aged dcSSc post-menopausal women. Male dcSSc patients with high serum E2 had significantly more heart involvement, a trend for higher skin thickness progression rate, and worse survival. Using Cox regression modeling, increased serum E2 levels in anti-Scl-70 antibody-positive dcSSc males were associated with an increased risk of death. CONCLUSIONS dcSSc males > 50 years old have higher levels of serum E2 compared to healthy controls and dcSSc post-menopausal women. Elevated serum E2 levels in dcSSc males are associated with heart involvement, trend to progression of dermal fibrosis, and, if anti-Scl-70 antibody positive, worse survival. Our study expands on previous work implicating E2 in dermal fibrosis in SSc and associates E2 levels with internal organ involvement and survival. These data suggest a role for estrogen imbalance in dcSSc.

Abstract
Aim The modified Rodnan skin score (mRSS) is a validated outcome measure for skin thickness in systemic sclerosis (SSc). Training has been shown to reduce variability in the measurement of mRSS. Our objective was to assess the inter‐ and intra‐observer variability of mRSS scoring using the proposed recommendations for training by the Scleroderma Clinical Trials Consortium (SCTC) and World Scleroderma Foundation (WSF). Method Fifty‐two trainees and eight adult SSc patients participated in the SSc skin scoring workshop that was conducted in two sessions by four teachers. Each session, attended by 26 trainees, had a teaching and evaluation phase. The teaching phase comprised of: (a) lecture on mRSS scoring; (b) video demonstration of mRSS scoring; and (c) live demonstration of mRSS on one SSc patient. In the evaluation phase, each trainee independently assessed the mRSS in four SSc patients. For intra‐observer reliability, 14 trainees re‐assessed the mRSS of two SSc patients whom they had previously examined. We computed the inter‐ and intra‐observer variability using a linear mixed model. Results For the evaluation phase, 34 (65.4%) trainees were within five units of the established teachers' score in 3 out of 4 patients. Overall, the whole group had acceptable inter‐observer variability (intra‐class correlation coefficient [ICC] = 0.71, mean = 8.64 and within‐patient standard deviation [SD] = 4.25). The intra‐observer ICC was 0.85 and within‐patient SD was 2.73. Conclusion There was good inter‐observer and excellent intra‐observer reliability. This is the first study examining the training of assessors using the SCTC/WSF recommendations and our results support the importance of standardized training for skin scoring.

Abstract
Objective.A multiethnic systemic sclerosis (SSc) cohort study to evaluate ethnic variations in disease manifestations, internal organ involvement, and survival.Methods.Adults who fulfilled the American College of Rheumatology/European League Against Rheumatism classification criteria for SSc between 1970 and 2017 were included. Self-reported ethnicity was categorized as European-descent white, Afro-Caribbean, Hispanic, Arab, East Asian, South Asian, First Nations, or Persian. The primary outcome was the time from diagnosis to death from all causes. Survival probabilities and median survival times were determined using Kaplan-Meier survival curves.Results.There were 1005 subjects evaluated, the majority of whom were European-descent white (n = 745, 74%), Afro-Caribbean (n = 58, 6%), South Asian (n = 70, 7%), and East Asian (n = 80, 8%). Compared to European-descent white subjects, East Asians less frequently had calcinosis (29% vs 9%, p = 0.002) and esophageal dysmotility (88% vs 69%, p = 0.002); Afro-Caribbeans more frequently had interstitial lung disease (31% vs 53%, p = 0.007); and First Nations subjects more frequently had diffuse cutaneous disease (35% vs 56%, p = 0.02) and diabetes (5% vs 33%, p = 0.03). We found no difference in the short-term survival across ethnicities. Hispanic subjects have better longterm survival (81.3%, 95% CI 63–100) compared to European-descent white subjects (55%, 95% CI 51–60). East Asians appear to have the longest median survival time (43.3 yrs) and Arabs the shortest median survival time (15 yrs). There was no significant difference in median survival times between Afro-Caribbean and European-descent white subjects (22.2 vs 22.6 yrs).Conclusion.Ethnic variations in some SSc disease manifestations are observed. However, this does not result in significant differences in short-term survival but may affect longterm survival.

Abstract
Objective: To characterize the clinical and laboratory profile of juvenile-onset compared to adult-onset systemic sclerosis in a large Brazilian cohort. Methods: Retrospective analysis of a cohort of 1016 systemic sclerosis patients followed at the Scleroderma Outpatient Clinic from two referral university centers in Brazil. Patients were classified as systemic sclerosis according to the 1980 American College of Rhaumatology (ACR) criteria. Juvenile-onset systemic sclerosis was defined if age at onset was <16 years. Results: Thirty-one (3.1%) patients were classified as juvenile-onset systemic sclerosis. These patients were predominantly females (90.3%), Caucasians (71.0%), and presented diffuse systemic sclerosis (51.6%), with mean age at onset of 12.71 years. Compared to the adult-onset patients, juvenile onset was associated with diffuse systemic sclerosis (p < 0.001), calcinosis (p < 0.001), myositis (p = 0.050), and lower frequency of interstitial lung disease (p = 0.050), pulmonary hypertension (p = 0.035), and esophageal (p = 0.005) involvement. Conclusion: Juvenile-onset systemic sclerosis characterized a distinct clinical pattern in this large series of systemic sclerosis patients, since it was predominantly associated with diffuse systemic sclerosis without significant organ involvement.

Abstract
Systemic sclerosis (SSc) is an orphan disease characterised by autoimmunity, fibrosis of the skin and internal organs, and vasculopathy. SSc may be associated with high morbidity and mortality. In this narrative review we summarise the results of a systematic literature research, which was performed as part of the European Reference Network on Rare and Complex Connective Tissue and Musculoskeletal Diseases project, aimed at evaluating existing clinical practice guidelines or recommendations. Only in the domains ‘Vascular & Ulcers’ (ie, non-pharmacological approach to digital ulcer), ‘PAH’ (ie, screening and treatment), ‘Treatment’ and ‘Juveniles’ (ie, evaluation of juveniles with Raynaud’s phenomenon) evidence-based and consensus-based guidelines could be included. Hence there is a preponderance of unmet needs in SSc referring to the diagnosis and (non-)pharmacological treatment of several SSc-specific complications. Patients with SSc experience significant uncertainty concerning SSc-related taxonomy, management (both pharmacological and non-pharmacological) and education. Day-to-day impact of the disease (loss of self-esteem, fatigue, sexual dysfunction, and occupational, nutritional and relational problems) is underestimated and needs evaluation.

Abstract
Introduction: Juvenile systemic sclerosis is an orphan disease. Currently, the majority of juvenile systemic sclerosis cohort studies are retrospective in design without standardized assessment. This study was conducted prospectively to investigate the difference in manifestations of limited cutaneous juvenile systemic sclerosis and diffuse cutaneous juvenile systemic sclerosis subtypes. An additional aim was to compare these data to other juvenile systemic sclerosis cohorts and a large adult systemic sclerosis cohort. Methods: Patients fulfilling the Paediatric Rheumatology European Society juvenile systemic sclerosis classification criteria were included. Clinical characteristics and patient-related outcomes were assessed. Results: In all, 88 patients with a mean disease duration of 3.5 years were enrolled, 72.5% with diffuse cutaneous juvenile systemic sclerosis with a mean modified Rodnan Skin score of 18 and 27.5% with limited cutaneous juvenile systemic sclerosis with mean modified Rodnan Skin score of 9. The mean age at the onset of Raynaud’s and first non-Raynaud’s symptoms was similar in both groups, approximately 9 and 10.5 years. Active digital tip ulcerations were present in 29% diffuse cutaneous juvenile systemic sclerosis and none in the limited cutaneous juvenile systemic sclerosis subjects (p = 0.005). Of those with cardiopulmonary testing, 3% of diffuse cutaneous juvenile systemic sclerosis and 23% of limited cutaneous juvenile systemic sclerosis group had cardiac involvement (p = 0.015), and 41% diffuse cutaneous juvenile systemic sclerosis and 22% of the limited cutaneous juvenile systemic sclerosis group had pulmonary involvement (p = 0.009). Physician global disease damage assessment was higher in the diffuse cutaneous juvenile systemic sclerosis group compared to the limited cutaneous juvenile systemic sclerosis group: 35 and 15 (p = 0.021). Discussion: The majority of this international juvenile systemic sclerosis cohort had diffuse cutaneous juvenile systemic sclerosis (72.5%) with more frequent vascular and pulmonary involvement compared to the limited cutaneous group, who had increased cardiac involvement. Our cohort reflects prior findings of published juvenile systemic sclerosis cohorts and emphasizes a difference in the presentation compared to adult-onset systemic sclerosis.

Abstract
We present a case of scleroderma overlap syndrome with systemic lupus erythematosus (SLE) including complications of both scleroderma renal crisis and lupus nephritis. Our patient was initially diagnosed with undifferentiated connective tissue disease in 1996. A diagnosis of scleroderma was made in 2010 after she developed scleroderma renal crisis. She remained stable until 2016, when she presented with Salmonella bacteremia, renal failure, nephrotic range proteinuria and microscopic hematuria. Laboratory findings were consistent lupus with positive ds-DNA, hypocomplementemia and repeat renal biopsy showed lupus nephritis.

Abstract
OBJECTIVE Systemic sclerosis (SSc) may overlap with systemic lupus erythematous (SLE). Little is known about the epidemiology, clinical characteristics, and survival of SSc-SLE overlap. We evaluated the prevalence of SSc-SLE overlap and differences in SSc characteristics, and compared survival with SSc without SLE. METHODS A cohort study was conducted including subjects who fulfilled the American College of Rheumatology (ACR)/European League Against Rheumatism classification criteria for SSc and/or the ACR criteria for SLE. The primary outcome was time from diagnosis to all-cause mortality. Survival was evaluated using Kaplan-Meier and Cox proportional hazard models. RESULTS We identified 1252 subjects (SSc: n = 1166, SSc-SLE: n = 86) with an SSc-SLE prevalence of 6.8%. Those with SSc-SLE were younger at diagnosis (37.9 yrs vs 47.9 yrs, p < 0.001), more frequently East Asian (5.5% vs 20%) or South Asian (5.1% vs 12%), had lupus anticoagulant (6% vs 0.3%, p < 0.001), anticardiolipin antibody (6% vs 0.9%, p < 0.001), and pulmonary arterial hypertension (PAH; 52% vs 31%, p < 0.001). Those with SSc-SLE less frequently had calcinosis (13% vs 27%, p = 0.007), telangiectasia (49% vs 75%, p < 0.001), and diffuse subtype (12% vs 35%, p < 0.001). There were no significant differences in the occurrence of renal crisis (7% vs 7%), interstitial lung disease (ILD; 41% vs 34%), and digital ulcers (38% vs 32%). Those with SSc-SLE had better median survival time (26.1 vs 22.4 yrs), but this was not statistically significant (log-rank p = 0.06). Female sex and diffuse subtype attenuated survival differences between groups (HR 1.07, 95% CI 0.67-1.67). CONCLUSION Patients with SSc-SLE are younger at diagnosis, more frequently have PAH, and less frequently have cutaneous manifestations of SSc. They should be monitored for ILD, renal crisis, and digital ulcers.

Abstract
Background. Exhaled nitric oxide (eNO) is a potential biomarker to distinguish systemic sclerosis (SSc) associated pulmonary arterial hypertension (PAH) and interstitial lung disease (ILD). We evaluated the discriminative validity, feasibility, methods of eNO measurement, and magnitude of differences across lung diseases, disease-subsets (SSc, systemic lupus erythematosus), and healthy-controls. Methods. Consecutive subjects in the UHN Pulmonary Hypertension Programme were recruited. Exhaled nitric oxide was measured at 50 mL/s intervals using chemiluminescent detection. Alveolar and conducting airway NO were partitioned using a two-compartment model of axial diffusion (CMAD) and the trumpet model of axial diffusion (TMAD). Results. Sixty subjects were evaluated. Using the CMAD model, control subjects had lower median (IQR) alveolar NO than all PAH subjects (2.0 (1.5, 2.5) versus 3.14 ppb (2.3, 4.0), p = 0.008). SSc-ILD had significantly lower median conducting airway NO compared to controls (1009.5 versus 1342.1 ml⁎ppb/s, p = 0.04). SSc-PAH had increased median (IQR) alveolar NO compared to controls (3.3 (3.0, 5.7) versus 2.0 ppb (1.5, 2.5), p = 0.01). SSc-PAH conducting airway NO inversely correlated with DLCO (r -0.88 (95% CI -0.99, -0.26)). Conclusion. We have demonstrated feasibility, identified that CMAD modeling is preferred in SSc, and reported the magnitude of differences across cases and controls. Our data supports discriminative validity of eNO in SSc lung disease.

Abstract
Systemic sclerosis (SSc) is a multisystem chronic disease characterized by the three cardinal pathological features, including autoimmunity/inflammation, vasculopathy, and fibrosis, with unknown etiology. Individual patients manifest these three components to variable degrees, resulting in the diverse heterogeneity of clinical presentation. The classification of SSc patients into relatively homogenous subtypes is helpful in the setting of daily clinical practice and the field of clinical and basic research. The classification of SSc has been continuously discussed over four decades based on the clinical and laboratory features, especially the extent of skin sclerosis and disease-related autoantibodies. This clinical classification system enables clinicians to provide general advice regarding prognosis and risk for internal organ disease, but only permits estimates of outcomes informed by population-based studies. On the other hand, the recent decade has seen much progress in the understanding of molecular aspects of SSc complex pathology, raising a discussion on molecular classification of SSc. The development of molecular targeting therapies, especially biologics, further strengthens the importance of molecular classification which aids the identification of potential responders for each treatment. Although a careful validation study is required for molecular classification of SSc due to its large heterogeneity, the advance of molecular classification would introduce a further modification into SSc classification system in the near future. Importantly, clinical and molecular classifications are not mutually exclusive, therefore the combination would facilitate the development of a better classification system of this complex heterogeneous disorder that is useful in both the clinical setting and research studies.

Abstract
Systemic sclerosis (SSc) is an autoimmune disease and a disabling condition that reduces life expectancy. Disease heterogeneity is a hallmark of SSc and classification has been hard to establish. Moreover, within the SSc spectrum, subsetting according to the extent of skin involvement has been universally accepted and is used both for research purposes but also for patient care. Therefore, limited cutaneous (lcSSc) and diffuse cutaneous (dcSSc), with different severity and survival, have been recognized for several years as distinct subsets. Any SSc research project using human material takes into account the cutaneous subsets but it is striking to see that the dcSSc subset has been the subject of the very large majority of the research projects so far. This editorial indicates the comparative epidemiology of the two cutaneous subsets and summarizes the main results coming from the recent registries about the respective outcomes of the patients. The data demonstrate the predominance of the lcSSc subset and challenge some ideas that could suggest that the lcSSc subset might be a benign condition. Some clues are also provided regarding the future possibility to enroll more patients having the lc subset in clinical trials and potential shared outcome measures.

Abstract
Introduction The aim of the study was to evaluate the effect of endothelin-1 receptor antagonists (ETRAs) on skin fibrosis in systemic sclerosis (SSc) patients from the (EULAR Scleroderma Trials and Research) EUSTAR cohort. Methods SSc patients from the EUSTAR cohort with at least three visits (pre-study visit without ETRA treatment, baseline and follow-up visit with ETRA treatment) were included. The control group consisted of SSc patients with the same inclusion criteria, but without ETRA treatment. The primary endpoint was the comparison of the delta change of the modified Rodnan skin score (mRSS) between baseline and follow-up in the ETRA versus the control group. Results Data on 75 ETRA treated (68 bosentan, 1 sitaxentan, 6 ambrisentan) and 969 control patients were included. The delta change of mRSS was not significantly different between the ETRA group and the control group (n = 969; 0 (-2-1) vs. n = 75; 0 (-2-1); p = 0.4). Similarly, subgroup analysis on patients with diffuse, extended SSc disease (mRSS ≥16) did not show differences in the delta change of mRSS between the ETRA group and the control group (n = 125; −1 [-7-0] vs. n = 23; −1 [-7-2], p = 0.8). Likewise, diffuse SSc patients with mRSS 7-21 at baseline, reflecting recently identified enrichment criteria for clinical trials, did not show any difference between the ETRA and the control group (n = 219; −1 [-3-1] vs. n = 27; −1 [-3-2]; p = 0.5). Conclusions This controlled, observational, real-life cohort study with a large sample size did not show effects of ETRAs on skin fibrosis in patients with SSc.
