Abstract
PURPOSE OF REVIEW Interstitial lung disease (ILD) is the leading cause of death in patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD). The American College of Rheumatology (ACR), in conjunction with the American College of Chest Physicians (CHEST), recently published clinical practice guidelines for the treatment of adults with systemic autoimmune rheumatic disease-associated ILD, including SSc-ILD. Herein, we summarize evidence from randomized trials evaluating the safety and efficacy of pharmacologic therapies for the treatment of SSc-ILD. RECENT FINDINGS In this review, we present findings from recent randomized controlled trials in SSc-ILD. The pharmacologic therapies discussed include immunosuppressive medications (mycophenolate, cyclophosphamide, rituximab, and tocilizumab) and antifibrotic medications (nintedanib and pirfenidone). SUMMARY Randomized trials provide an evidence base for the SSc-ILD treatment recommendations put forth in the ACR/CHEST Guidelines for the treatment of ILD in people with systemic autoimmune rheumatic diseases. These guidelines will help inform clinical practice and highlight areas in which further research is needed.

Arch Dermatol Res 2024; 316:553. [PMID: 39172247 DOI: 10.1007/s00403-024-03248-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2024] [Revised: 07/12/2024] [Accepted: 07/24/2024] [Indexed: 08/23/2024]
Abstract
Prior evidence suggests that altered energy metabolism plays a crucial role in the development of fibrotic diseases. Recent research indicates that systemic sclerosis (SSc) patients have potentially benefited from energy management, implying that basal metabolic rate (BMR), a vital energy metabolic parameter, may be related to SSc. However, the causal effect of BMR on SSc remains unknown. Thus, we aimed to elucidate the causal links between BMR and SSc. Based on summary statistics from the genome-wide association studies (GWAS) database, two-sample Mendelian randomization (MR) was applied to explore causality between BMR and SSc. The causal relationships were assessed employing inverse variance weighted (IVW), MR-Egger, and weighted median (WM) methods. Meanwhile, several sensitivity analyses were carried out to ensure the robustness of the findings. There was an underlying genetic association of BMR on SSc (OR = 0.505, 95% CI: 0.272-0.936, P = 0.030). Moreover, no significant causal effect between SSc and BMR was observed in the reverse MR analysis (OR = 0.999, 95% CI: 0.997-1.001, P = 0.292). According to the sensitivity analysis, the presence of heterogeneity and genetic pleiotropy was not detected. Our findings, derived from a genetic perspective, provide robust evidence of a causal connection between BMR and SSc. To verify these results and clarify the potential mechanisms, further research is warranted.

A Prospective Observational Study of Disease Severity and Mortality in Hispanic American Patients With Systemic Sclerosis. Arthritis Care Res (Hoboken) 2024; 76:768-776. [PMID: 38221717 PMCID: PMC11132947 DOI: 10.1002/acr.25300] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Revised: 12/10/2023] [Accepted: 01/10/2023] [Indexed: 01/16/2024]
Abstract
OBJECTIVE To characterize disease manifestations in Hispanic American patients with systemic sclerosis (SSc) in comparison with non-Hispanic White and Black patients. METHODS Longitudinal clinical characteristics were collected prospectively in the Genetics versus Environment in Scleroderma Outcome Study cohort. All patients fulfilled the classification criteria for SSc and had a disease duration less than five years at enrollment. RESULTS A cohort of 427 patients, consisting of 124 Hispanic, 220 non-Hispanic White, and 83 non-Hispanic Black participants were examined. At enrollment, Hispanic patients were significantly younger but had longer disease duration, higher frequency of U1-RNP positivity as well as concurrent systemic lupus erythematosus (SLE) diagnosis, and lower income and educational levels in comparison to non-Hispanic White patients. Compared with non-Hispanic Black patients, Hispanic patients had more frequently limited cutaneous involvement and anticentromere antibodies. In the longitudinal analysis, Hispanic patients had significantly lower forced vital capacity percents predicted (point estimate, -9.3%; P < 0.001) than non-Hispanic White but not Black patients. Hispanic patients had similar longitudinal modified Rodnan Skin Scores like non-Hispanic White patients but lower measurements than non-Hispanic Black patients (point estimate, -3.2; P = 0.029). Hispanic patients had significantly higher serially obtained perceived functional disability scores than White patients (point estimate, 0.29; P < 0.001). Hispanic patients also had higher mortality rates than White Americans even after adjustment for age, gender, and socioeconomic statuses. CONCLUSION Hispanic patients have higher likelihood of having U1-RNP positivity and SLE overlap, more severe restrictive lung disease, as well as higher rate of mortality than non-Hispanic White patients.

Abstract
Objective The study aimed to assess the construct validity of the Arab Hand Function Index and the Arabic Health Assessment Questionnaire in Algerian patients with systemic sclerosis. Methods Consecutive Algerian patients who fulfilled the American College of Rheumatology/European League Against Rheumatism criteria for systemic sclerosis were included. In addition to disease characteristics, global disability and hand disability were assessed using the Arabic Health Assessment Questionnaire and the Arab Hand Function Index, respectively. Construct validity was assessed by convergent and divergent validity (Spearman's rank correlation coefficient) and factor analysis. The scale reliability was assessed using the Cronbach's alpha. Results We evaluated 100 systemic sclerosis patients (83 females) of mean ± standard deviation age 46.7 ± 12.3 years, including 59 limited cutaneous systemic sclerosis and 41 diffuse cutaneous systemic sclerosis. Raynaud's phenomenon was detected in 99 patients and digital ulcers in 25. Gastrointestinal tract involvement and interstitial lung disease were detected in 86/100 (86%) and 46/72 (63.9%) patients, respectively. Anti-topoisomerase I and anti-centromere antibodies were detected in 33/76 (43.4%) and 23/76 (30.3%) patients, respectively. The Arab Hand Function Index had a good construct validity with a total score explaining 61% of the variance of the Arabic Health Assessment Questionnaire which also had a good construct validity. Factor analysis of the Arab Hand Function Index and the Arabic Health Assessment Questionnaire items extracted two factors explaining 64% of the variance for the Arab Hand Function Index and one factor explaining 55% of the variance for the Arabic Health Assessment Questionnaire. The Arab Hand Function Index and the Arabic Health Assessment Questionnaire were reliable questionnaires with a Cronbach's alpha >0.8. Conclusion In Algerian patients with systemic sclerosis, Arab Hand Function Index and Arabic Health Assessment Questionnaire have a good construct validity and reliability.

Abstract
Interstitial lung disease (ILD) is recognized a prognostic factor and leading cause of death in patients with systemic sclerosis (SSc). The aim of the present study is to clarify factors at an initial visit that are associated with the deterioration of ILD in SSc patients with anti-topoisomerase I (anti-topo I) antibodies. This was a single-center, retrospective, observational study. Fifty-three consecutive SSc patients with anti-topo I antibodies were included in this study. Of the 53 patients, 43 had ILD at their initial visit, whereas 10 did not. We examined the clinical and immunological factors at an initial visit that were associated with the deterioration of ILD. The deterioration of ILD was defined as the administration of intravenous cyclophosphamide (IVCY) therapy. In this cohort, 45 (85%) patients had ILD at the time of the final observation, and only two who did not have ILD at their initial visit developed ILD during the follow-up period. Until the final observation, 26 (49%) patients received IVCY therapy for the progression of ILD. The age at onset, disease duration, SSc subtype, and skin score were similar between patients with and those without IVCY therapy. Approximately 60% (26 of 43) of patients with ILD at their initial visit received IVCY therapy. On the other hand, none of the 10 patients without ILD at their initial visit received IVCY therapy. Our multivariate analyses using Cox proportional hazards regression model revealed that the presence of ILD at an initial visit was an independent factor associated with the introduction of IVCY therapy (odds ratio, 2.8e+7 [95% confidence interval, 1.8e+17-uncalculated], p = 0.0048). Although anti-topo I antibodies are strongly associated with ILD, it was unlikely for SSc patients with anti-topo I antibodies to receive IVCY therapy when they did not have ILD at an initial visit.

Abstract
Systemic sclerosis (SSc), or scleroderma, is a rare, complex, systemic autoimmune disease of unknown aetiology, characterized by high morbidity and mortality often resulting from cardiopulmonary complications such as interstitial lung disease and pulmonary arterial hypertension. Despite substantial progress in unravelling the pathways involved in the pathogenesis of SSc and the increasing number of therapeutic targets tested in clinical trials, there is still no cure for this disease, although several proposed treatments might limit the involvement of specific organs, thereby slowing the natural history of the disease. A specific focus of recent research has been to address the plethora of unmet needs regarding the global management of SSc-related interstitial lung disease, including its pathogenesis, early diagnosis, risk stratification of patients, appropriate treatment regimens and monitoring of treatment response, as well as the definition of progression and predictors of progression and mortality. More refined stratification of patients on the basis of clinical features, molecular signatures, identification of subpopulations with distinct clinical trajectories and implementation of outcome measures for future clinical trials could also improve therapeutic management strategies, helping to avoid poor outcomes related to lung involvement.

Abstract
Objectives This study aimed to evaluate the clinical and serological profile in systemic sclerosis (SSc) by comparing females and males. Patients and methods This retrospective study was conducted with 215 SSc patients (193 females, 22 males; mean age: 50.1±14.5 years; range, 16 to 88 years) between September 2005 and September 2020. Disease severity was calculated by the Medsger severity score. Males and females were compared for clinical and serological markers. Results Females more frequently had esophageal involvement (p=0.003), telangiectasias (p=0.03), and antinuclear antibodies (p=0.04). Males more frequently had fingertip scars (p=0.03), digital ulcers (p=0.006), and a worse median Medsger severity score (6 in males vs. 4 in females, p=0.05). Conclusion In the studied sample, males had more severe disease than females with greater repercussions in periferic circulatory system.

Abstract
Objective The course of systemic sclerosis-associated interstitial lung disease (SSc-ILD) is highly variable and different from continuously progressive idiopathic pulmonary fibrosis (IPF). Most proposed definitions of progressive pulmonary fibrosis or SSc-ILD severity are based on the research data from patients with IPF and are not validated for patients with SSc-ILD. Our study aimed to gather the current evidence for severity, progression and outcomes of SSc-ILD.Methods A systematic literature review to search for definitions of severity, progression and outcomes recorded for SSc-ILD was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines in Medline, Embase, Web of Science and Cochrane Library up to 1 August 2023.Results A total of 9054 papers were reviewed and 342 were finally included. The most frequent tools used for the definition of SSc-ILD progression and severity were combined changes of carbon monoxide diffusing capacity (DLCO) and forced vital capacity (FVC), isolated FVC or DLCO changes, high-resolution CT (HRCT) extension and composite algorithms including pulmonary function test, clinical signs and HRCT data. Mortality was the most frequently reported long-term event, both from all causes or ILD related.Conclusions The studies presenting definitions of SSc-ILD 'progression', 'severity' and 'outcome' show a large heterogeneity. These results emphasise the need for developing a standardised, consensus definition of severe SSc-ILD, to link a disease specific definition of progression as a surrogate outcome for clinical trials and clinical practice.PROSPERO registration number CRD42022379254.Cite Now.

Abstract
The idiopathic inflammatory myopathies (IIMs) are a heterogeneous group of systemic autoimmune diseases that affect the skeletal muscles and can also involve the skin, joints, lungs and heart. The epidemiology of IIM is obscured by changing classification criteria and the inherent shortcomings of case identification using healthcare record diagnostic coding. The incidence of IIM is estimated to range from 0.2 to 2 per 100,000 person-years, with prevalence from 2 to 25 per 100,000 people. Although the effects of age and gender on incidence are known, there is only sparse understanding of ethnic differences, particularly in indigenous populations. The incidence of IIM has reportedly increased in the twenty-first century, but whether this is a genuine increase is not yet known. Understanding of the genetic risk factors for different IIM subtypes has advanced considerably. Infections, medications, malignancy and geography are also commonly identified risk factors. Potentially, the COVID-19 pandemic has altered IIM incidence, although evidence of this occurrence is limited to case reports and small case series. Consideration of the current understanding of the epidemiology of IIM can highlight important areas of interest for future research into these rare diseases.

Abstract
PURPOSE OF REVIEW To provide updated information on the prevalence, pathogenesis, diagnostics, and therapeutics of calcinosis cutis associated with systemic sclerosis (SSc). RECENT FINDINGS Observational studies show ethnic and geographical differences in the prevalence of calcinosis. In addition to clinical and serological associations, biochemical studies and in-vivo models have attempted to explain theories behind its pathogenesis, including prolonged state of inflammation, mechanical stress, hypoxia, and dysregulation in bone and phosphate metabolism. Long-term use of proton pump inhibitors may increase the risk for calcinosis in SSc. Few single center observational studies have shown mild benefit with minocycline and topical sodium thiosulfate. SUMMARY Calcinosis cutis is the deposition of insoluble calcium in the skin and subcutaneous tissues. It affects up to 40% of SSc patients and causes significant morbidity. Long disease duration, features of vascular dysfunction, and osteoporosis have been associated with calcinosis. Altered levels of inorganic pyrophosphate and fibroblast growth factor-23 have been implicated in dysregulated phosphate metabolism that may lead to calcinosis in SSc. Plain radiography can help with diagnosis and quantifying the calcinosis burden. Surgical treatment remains the most effective therapy when feasible. At present, no medical therapies have proven efficacy in large randomized controlled trials.

Abstract
OBJECTIVE To assess how and to what extent socioeconomic status and ethnicity/race of participants are reported in randomized controlled trials (RCTs) on systemic sclerosis (SSc), and to estimate the representativeness of different ethnic/racial groups in SSc RCTs. METHODS We searched all published RCTs on SSc indexed in PubMed. We retrieved information on main features of RCTs published from 2000 onward and recorded for each study whether race/ethnicity was reported; how ethnicity/race was defined and assigned; and the number of patients included for each racial/ethnic group. Multivariable logistic regression was used to identify factors associated with race/ethnicity reporting. Proportion of races/ethnicities included in US-based RCTs on SSc was examined and compared with US demographic data. RESULTS We included 106 studies, mostly conducted in Europe (42%) or North America (25%), published after 2010 (74%), and enrolling a total of 6,693 patients. About one-third of studies provided information about race/ethnicity, with no improved reporting over time. Only 2 papers reported patient's socioeconomic status. Study location (US or intercontinental) was the only significant factor associated with a better reporting of race/ethnicity in multivariable analysis. In studies where race/ethnicity was reported, White patients were mostly represented (79%), followed by Asian (7%), and African American (6%). In the sensitivity analysis limited to studies from the US, underrepresentation of African American patients was observed in the 2000-2010 time period, but not later. CONCLUSION Documentation of race/ethnicity and socioeconomic status is poor in RCTs on SSc. More effort should be made to document race/ethnicity and socioeconomic status and to promote diversity in SSc RCTs.

Abstract
Systemic sclerosis (SSc) is a heterogeneous disease comprising of a wide spectrum of ages of onset, sex-based differences, ethnic variations, disease manifestations, differential serologic profiles, and variable response to therapy resulting in reduced health-related quality of life, disability, and survival. The ability to subset groups of patients with SSc can assist with refining the diagnosis, guide appropriate monitoring, inform aggressiveness of immunosuppression, and predict prognosis. The ability to subset patients with SSc has several important practical implications for patient care.

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.

BMC Complement Med Ther 2023; 23:62. [PMID: 36810081 PMCID: PMC9942410 DOI: 10.1186/s12906-023-03885-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Accepted: 02/13/2023] [Indexed: 02/23/2023] Open
Abstract
BACKGROUND Systemic sclerosis (SSc; also known as "scleroderma") is an autoimmune disorder characterized by extensive fibrosis, vascular changes, and immunologic dysregulation. Baicalein (phenolic flavonoid derived from Scutellaria baicalensis Georgi) has been used to treat the pathological processes of various fibrotic and inflammatory diseases. In this study, we investigated the effect of baicalein on the major pathologic characteristics of SSc: fibrosis, B-cell abnormalities, and inflammation. METHODS The effect of baicalein on collagen accumulation and expression of fibrogenic markers in human dermal fibroblasts were analyzed. SSc mice were produced by injecting bleomycin and treated with baicalein (25, 50, or 100 mg/kg). The antifibrotic features of baicalein and its mechanisms were investigated by histologic examination, hydroxyproline assay, enzyme-linked immunosorbent assay, western blotting and flow cytometry. RESULTS Baicalein (5-120 μM) significantly inhibited the accumulation of the extracellular matrix and fibroblast activation in transforming growth factor (TGF)-β1- and platelet derived growth factor (PDGF)-induced human dermal fibroblasts, as evidenced by abrogated deposition of total collagen, decreased secretion of soluble collagen, reduced collagen contraction capability and downregulation of various fibrogenesis molecules. In a bleomycin-induced model of dermal fibrosis in mice, baicalein (25-100 mg/kg) restored dermal architecture, ameliorated inflammatory infiltrates, and attenuated dermal thickness and collagen accumulation in a dose-dependent manner. According to flow cytometry, baicalein reduced the proportion of B cells (B220+ lymphocytes) and increased the proportion of memory B cells (B220+CD27+ lymphocytes) in the spleens of bleomycin-induced mice. Baicalein treatment potently attenuated serum levels of cytokines (interleukin (IL)-1β, IL-2, IL-4, IL-6, IL-17A, tumor necrosis factor-α), chemokines (monocyte chemoattractant protein-1, macrophage inflammatory protein-1 beta) and autoantibodies (anti-scleroderma 70 (Scl-70), anti-polymyositis-scleroderma (PM-Scl), anti-centromeres, anti-double stranded DNA (dsDNA). In addition, baicalein treatment can significantly inhibit the activation of TGF-β1 signaling in dermal fibroblasts and bleomycin-induce mice of SSc, evidenced by reducing the expression of TGF-β1 and IL-11, as well as inhibiting both small mother against decapentaplegic homolog 3 (SMAD3) and extracellular signal-related kinase (ERK) activation. CONCLUSIONS These findings suggest that baicalein has therapeutic potential against SSc, exerting modulating B-cell abnormalities, anti-inflammatory effects, and antifibrosis.

Abstract
Quality improvement is an emerging field, that applies principles of improvement science and utilizes measurement methods with the aim of improving patient care. Systemic sclerosis (SSc) is a systemic autoimmune rheumatic disease associated with increased healthcare burden, cost, morbidity, and mortality. Gaps in delivering care to patients with SSc have been consistently observed. In this article, we introduce the discipline of quality improvement and its use of quality measures. We summarize and comparatively evaluate three sets of quality measures that have been proposed to evaluate the quality of care of patients with SSc. Finally, we highlight the areas of unmet needs and indicate future directions for quality improvement and quality measures in SSc.

Abstract
Background We aimed to compare the clinical characteristics of patients with systemic sclerosis (SSc) with or without interstitial lung disease (ILD) to identify relationships with the presence of ILD in SSc at a single center in China. Methods A cross-sectional study was conducted using retrospective data from the Chinese Rheumatology Data Center. Patients diagnosed with SSc at the Second Affiliated Hospital of Nanchang University between 2013 and 2022 were included. Demographic and clinical characteristics were compared between patients with SSc with and without ILD. Logistic regression analyses were performed to explore these associations. Results A total of 227 patients with SSc were included (male:female ratio = 1:4.82), of which 121 (53.3%) were accompanied with ILD. SSc patients with ILD had a higher percentage of diffuse cutaneous systemic sclerosis (dcSSc), sclerodactyly, loss of finger pad, muscle involvement, left ventricular diastolic dysfunction (LVDD), and pulmonary hypertension (PAH), elevated Krebs von den Lungen-6 (KL-6), and elevated ferritin than those without ILD, and a higher modified Rodnan skin score (mRSS), neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) (all P < 0.05). Antinuclear antibody (ANA) and anti-scleroderma-70 (anti-Scl-70) positivity was presented frequently in SSc patients with ILD, while SSc patients without ILD were more often anti-centromere antibody (ACA) positive (all P < 0.05). On the multivariable analysis, muscle involvement [OR 2.551 (95% CI 1.054-6.175), P = 0.038], LVDD [OR 2.360 (95% CI 1.277-4.361), P = 0.006], PAH [OR 9.134 (95% CI 2.335-35.730), P = 0.001], dcSSc [OR 2.859 (95% CI 1.489-5.487), P = 0.002], PLR [OR 1.005 (95% CI 1.001-1.008), P = 0.020], elevated KL-6 [OR 2.033 (95% CI 1.099-3.763), P = 0.024], and anti-Scl-70 [OR 3.101 (95% CI 1.647-5.840), P < 0.001] were statistically significant associations with SSc patients with ILD. Conclusion Systemic sclerosis was found mainly in females. Several important differences in clinical and laboratory characteristics have been demonstrated between SSc patients with or without ILD. Muscle involvement, LVDD, PAH, dcSSc, PLR, elevated KL-6, and Anti-Scl-70 antibody may be associated with SSc in patients with ILD.

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
There is an increasing body of literature suggesting a relationship between environmental factors and the development of systemic sclerosis (SSc). These include occupational exposures, chemical materials, medications, alterations in the microbiome, and dysbiosis. Environmental exposures may impact epigenetic regulation thereby triggering an aberrant immune response resulting in the clinical and serologic phenotype that we diagnose as SSc. Screening and studying putative triggers will not only improve our understanding of the pathogenesis of SSc but also inform the institution for protective measures.

Abstract
Abstract
Purpose of Review
Interstitial lung disease (ILD) is the leading cause of mortality in systemic sclerosis, a rare autoimmune disease characterised by fibrosis and vasculopathy. The variety of phenotypes in SSc-ILD have inspired multiple studies aimed at the identification of biomarkers which can provide disease-specific information but due to the complex pathogenesis of SSc-ILD, it has been challenging to validate such markers. We provide a comprehensive update on those most studied along with emerging biomarkers.
Recent Findings
We review the up-to-date findings with regard to the use of well-studied molecular biomarkers in SSc-ILD along with novel biomarkers offering promise as prognostic markers such as IGFBP-2 and IGFBP-7, the adipokine CTRP9, endothelial progenitor cells, and cellular markers such as CD21lo/neg B cells. Expression profiling data is being used in SSc patients to determine genetic and epigenetic clusters which shed further light on mechanisms involved in the pathogenesis of SSc-ILD and are likely to uncover novel biomarkers.
Summary
With the exception of autoantibodies, there are no routinely measured biomarkers in SSc-ILD and reliable validation of the many potential biomarkers is lacking. Identifying biomarkers which can offer diagnostic and prognostic certainty may help patients to receive preventative treatment as part of a personalised medicine approach.

Abstract
AIM To study the economic impact of systemic sclerosis (SSc) in the patients attending Rheumatology clinics in Waikato Hospital, Hamilton, New Zealand (NZ). There is currently no bottom-up data on this in NZ. METHODS This is a retrospective cross-sectional questionnaire-based study, including demographics, costs related to SSc, quality of life measures including the short-form survey (SF-36) the scleroderma health assessment questionnaire-visual analog scale (SHAQ-VAS), the NZ index of Deprivation (NZiDep), and work limitations questionnaire (WLQ). Direct health costs include patient-reported costs and costs incurred by the public health system. Indirect costs include calculated loss of work productivity. Comparisons were made between age, gender, disease duration, and disease subtype (diffuse, limited, and overlap syndromes). RESULTS Participants fulfilled the 2013 ACR/EULAR criteria for SSc. The study was completed by 86 (65.5%) patients, 77 (90%) were females, 19 (22%) had diffuse cutaneous systemic sclerosis (dcSSc), 72 (83%) were NZ European (NZE), seven(8%) were Māori or NZE/Māori. Seventy-six (41.8%) were employed. The average total costs for 6 months were NZ$ 444.50 with the highest costs in the dcSSc sub-group at NZ$ 598.00. The costs incurred by the Hospital for the 2018/2019 fiscal year was NZ$ 3091 per patient. The SF-36 score was lower compared with the general population, mean SHAQ was 0.82. Mean summative WLQ scores were: Time management 21.7, Physical demands 62.5, Interpersonal 23.6, Output demands 23.8. The calculated percentage productivity loss was 46.5%. CONCLUSIONS This study has shown high health-related costs of SSc in NZ, with reduction in employment, work productivity, and quality of life. The contributors to the costs included physical disability and loss of productivity.

Temporal Trends in Mortality in Patients with Systemic Sclerosis in Public Hospitals Across Mexico from 1998-2017. Arch Med Res 2022; 53:610-616. [PMID: 36038446 DOI: 10.1016/j.arcmed.2022.07.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 06/05/2022] [Accepted: 07/25/2022] [Indexed: 11/30/2022]
Abstract
OBJECTIVE To investigate national temporal trends over time in mortality rates in patients with systemic sclerosis (SSc) in Mexico between 1998 and 2017. METHODS Deaths between 1998 and 2017 were extracted from General Board of Health Information (DGIS) Open Access datasets. 2We identified all persons aged ≥15 years with a diagnosis of SSc (ICD-10 code M34). We calculated the age-standardized mortality rate (ASMR) for SSc and non-SSc (information provided by the National Institute of Statistics, Geography, and Informatics). A Joinpoint regression model was used to determine mortality trends by sex and geographic regions. Annual percentage change (APC) and average APC (AAPC) were calculated using Joinpoint analysis. RESULTS From 1998 to 2017, the overall ASMR of SSc increased (AAPC = 2.5%), whereas the ASMR for non-SSc remained stable. By subpopulations, females, and males with SSc had a significant uptrend in the ASMR (APC = 4.6 and 4.4%, respectively), between 1998 and 2008 for the former and between 1998 and 2010 for the later. Females had a non-significant ASMR uptrend between 2008 and 2017 and males a non-significant ASMR decline between 2010 and 2017. Women had a higher SSc-ASMR to non-SSc-ASMR ratio than males. The relative cumulative change between 1998 and 2017 differed between females (78.1%) and males (50.8%), and residents of the Southern region had the largest cumulative change (147.8%). CONCLUSIONS SSc mortality rate increased in Mexico between 1998 to 2017, with SSc mortality higher than non-SSc mortality. However, the SSc mortality rate steeply increased in the first ten years but has plateaued in the last 10 years of the study period. Variations by sex and geographic regions were also identified.

[PMID: 36078943 PMCID: PMC9456668 DOI: 10.3390/jcm11175013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2022] [Revised: 08/15/2022] [Accepted: 08/22/2022] [Indexed: 11/16/2022] Open
Abstract
It is important for clinicians to determine the risk of worsening trajectories in SSc patients. The Scleroderma Clinical Trials Consortium (SCTC) Damage Index (DI) has been developed to quantify organ damage and shows good capability for mortality and morbidity prediction in patients with SSc. This retrospective study aimed to describe the SCTC-DI in Chinese SSc patients and to find features predicting worse organ damage trajectories based on SCTC-DI. A total of 433 SSc patients who met the inclusion criteria in the Peking University Third Hospital (PKUTH-SSc) and People’s Hospital SSc cohort (PKUPH-SSc) were recruited for our study. Organ damage was relatively mild in our Chinese SSc cohort compared to other cohorts, with a mean SCTC-DI of 5.21 ± 4.60. We used both SCTC-DI ≥ 6 and ≥4 to define the high burden of organ damage and established two risk models by the LASSO algorithm, which revealed good identification of high organ damage burden (AUC = 0.689, 95% CI 0.636 to 0.742, p < 0.001 in SCTC-DI ≥ 6 model; AUC = 0.694, 95% CI 0.641 to 0.746, p < 0.001 in modified SCTC-DI ≥ 4 model). The anemia index at the baseline was included in these two models and was also independently related to organ damage progression (HR = 1.75, 95% CI 1.16 to 2.66, p = 0.008). In addition, the presence of an anti-Scl-70 autoantibody was also a predictor of progression (HR = 1.91, 95% CI 1.22 to 2.99, p = 0.005). In conclusion, anemia at the baseline was an important indicator for worse organ damage trajectories in SSc patients. We recommend using hemoglobin as a potential biomarker to evaluate organ damage in SSc patients.

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.

Abstract
Systemic sclerosis is a multisystemic autoimmune disease characterized by vasculopathy and fibrosis. Racial factors exert a significant influence on the epidemiology, clinical manifestations, antibody profile, mortality and genetic factors in systemic sclerosis. In this review, we examined Asian systemic sclerosis cohorts reported in Asia and multi-racial cohort studies to evaluate the disease characteristics and outcomes of systemic sclerosis in Asians. Asian patients have distinct genetic susceptibility to systemic sclerosis, younger age of systemic sclerosis onset, higher frequency of diffuse skin involvement, different autoantibody profiles such as higher frequency of anti-Scl70 and anti-U1-RNP antibodies, and more severe clinical phenotype. There was a suggestion of poorer survival among Asians that may be contributed by more severe disease, socioeconomic factors and differences in healthcare systems. Recognizing the influence of racial differences in systemic sclerosis disease course is important as it has implications for appropriate treatment, monitoring and prognostication.

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
Background Systemic sclerosis (SSc) is a rare detrimental disease warranting global research efforts. Evaluating how socio-economic factors impact country research output on SSc could help to identify solutions advancing research. Methods Publication production on SSc during 1969–2018 and data for structural and policy factors for WHO member countries were collected from public sources. Associations between SSc research output and country-level factors were investigated through panel regression. Difference-in-differences analysis further assessed the causal effects of rare disease legislation. Results SSc publications demonstrated exponential growth (r = 0.9410, as against an r = 0.8845 after linear adjustment), but were concentrated in high-income countries (HICs). Ten countries, nine of which were HICs, published 12,261 (77.5%) SSc publications but another 87 countries produced none. Gross domestic products (GDP), population and expenditure on research and development were positively associated with SSc publications (p < 0.001). Higher health expenditure was only found to be associated with increased SSc publications in HICs (p < 0.001). Rare disease legislation increased annual publication production by 62.8% (95% CI 0.390–0.867; p < 0.001) averagely. In middle-income countries (MICs), the effect was especially swift and lasting. No significant impact was found with GDP per capita, female percentage, and political indicators. Conclusions SSc research output increased over time with substantial country disparities. Effective health policies facilitating research should be expanded especially among MICs to accelerate research advancement.

THE LANCET. RHEUMATOLOGY 2021; 3:e834-e843.

Abstract
BACKGROUND Preliminary criteria for the very early diagnosis of systemic sclerosis (VEDOSS) have been previously proposed to identify signs and symptoms in patients with Raynaud's phenomenon. Patients with all signs or symptoms of the VEDOSS criteria already fulfil the 2013 American College of Rheumatology-European League Against Rheumatism (ACR-EULAR) classification criteria for systemic sclerosis. However, prospective data for the evolution to fulfilling these criteria do not exist. We therefore aimed to determine the clinical value of the VEDOSS criteria to identify patients with Raynaud's phenomenon who progress to systemic sclerosis within 5 years. METHODS The VEDOSS project was a multicentre, longitudinal registry study done in 42 European Scleroderma Trial and Research group centres located in 20 countries in Europe, North America, and South America. Patients with Raynaud's phenomenon were eligible for enrolment. Those who had fulfilled the 1980 ACR or the 2013 ACR-EULAR classification criteria for systemic sclerosis, as well as of any other ACR or EULAR classification criteria for other definite connective tissue diseases at enrolment were excluded. Data were recorded each year during follow-up visits and included the four VEDOSS criteria (ie, positivity for antinuclear antibodies [ANAs], puffy fingers, systemic sclerosis-specific autoantibodies, and abnormal nailfold capillaroscopy). The primary endpoint was the fulfilment of the 2013 ACR-EULAR classification criteria for systemic sclerosis (ie, progression from enrolment to follow-up). Proportion of progressors and VEDOSS criteria interaction were reported descriptively. Predictors of progression of the distinct VEDOSS criteria interactions were determined based on the point prevalence at 5 years. To investigate the intermediate course of progression of the distinct VEDOSS criteria and their combinations, Kaplan-Meier analysis was done. RESULTS Between March 1, 2010, and Oct 4, 2018, we enrolled 1150 patients with Raynaud's phenomenon in the VEDOSS database. 764 (66·4%) of 1150 patients met the VEDOSS criteria for study inclusion. Of the 764 patients, 553 (72·4%) had at least one available follow-up visit and the median duration of follow-up was 3·6 years (IQR 1·7-5·8). The mean age was 45·9 years (SD 15·0), 507 (91·7%) of 553 participants were female, and the median time since the onset of Raynaud's phenomenon was 4·0 years (IQR 1·7-10·0). At baseline, 401 (73·7%) of 544 patients with Raynaud's phenomenon had detectable ANA, with 208 (39·5%) of 527 patients positive for systemic sclerosis-specific autoantibodies. Nailfold capillaroscopy abnormalities were present in 182 (36·0%) of 505 patients and puffy fingers were detected in 96 (17·8%) of 540 at baseline. 1885 follow-up visits were recorded. 254 (45·9%) of 553 patients completed the study with progression or a 5-year follow-up; of whom, 133 reached the primary endpoint, resulting in an overall progression rate of 52·4%. The absence of ANA at baseline was the factor most strongly associated with a lack of progression within 5 years, with only four (10·8%) of 37 ANA-negative patients progressing. Conversely, positivity at baseline for systemic sclerosis-specific autoantibodies and puffy fingers was the combination having the highest risk of progression (16 [94·1%] of 17). INTERPRETATION Our results from the VEDOSS project offers a useful tool for a stratified risk approach to patients with Raynaud's phenomenon. The absence of ANA is a strong protective factor that identifies patients with very low risk of developing systemic sclerosis whereas the presence of one or two VEDOSS criteria in patients with Raynaud's phenomenon confers a progressively higher risk for systemic sclerosis over time. This stratification tool can be used both for clinical management and to inform early interventional trials. FUNDING European Scleroderma Trial And Research and World Scleroderma Foundation.

Abstract
BACKGROUND/AIMS Systemic sclerosis (SSc) is associated with a wide range of gastrointestinal (GI) changes. The University of California-Los Angeles Scleroderma Clinical Trial Consortium Gastrointestinal Tract (UCLA SCTC GIT 2.0) instrument is a self-administered GI assessment instrument for patients with SSc. We developed a Korean version of the UCLA SCTC GIT 2.0 instrument and evaluated its reliability and internal consistency. METHODS The participants were 37 Korean patients with SSc. Translation and cross-cultural adaptation of the UCLA SCTC GIT 2.0 were performed according to international standardized guidelines. We evaluated reproducibility by calculating the intraclass correlation coefficients and assessed the internal consistency of the Korean version of the UCLA SCTC GIT 2.0. We assessed its construct validity by evaluating its correlations with the Short Form Health Survey version 2 and EQ-5D scores by means of Spearman correlation analyses. RESULTS Patients with SSc were mostly women (89.19%) with a mean age of 52.2 years, median disease duration of 24 months, and median modified Rodnan total skin score of 4. The median total GIT score on the UCLA SCTC GIT 2.0 was 0.3. The UCLA SCTC GIT 2.0 Korean version showed excellent internal consistency (Cronbach's α of total GIT score = 0.863). Most domains of the ULCA SCTC GIT 2.0 were correlated with those of the EuroQol (EQ)-5D score. CONCLUSION The Korean version of the UCLA SCTC GIT 2.0 has acceptable internal consistency, reliability, and validity. Therefore, it can be used to assess GIT involvement in Korean patients with SSc.

Abstract
Interstitial lung disease (ILD) affects approximately 50% of patients with systemic sclerosis (SSc) and is the leading cause of death in SSc. Our objective was to gain insight into the progression of SSc-associated ILD (SSc-ILD). Using data from longitudinal clinical trials and observational studies, we assessed definitions and patterns of progression, risk factors for progression, and implications for treatment. SSc-ILD progression was commonly defined as exceeding specific thresholds of lung function worsening and/or increasing radiographic involvement. One definition used in several studies is decline in forced vital capacity (FVC) of ≥10%, or ≥5-10% plus a decline in diffusing capacity of the lung for carbon monoxide ≥15%. Based on these criteria, 20-30% of patients in observational cohorts develop progressive ILD, starting early in the disease course and progressing at a highly variable rate.Risk factors such as age, FVC, extent of fibrosis and presence of anti-topoisomerase I antibodies can help predict progression of SSc-ILD, though composite risk scores may offer greater predictive power. Whilst the variability of the disease course in SSc-ILD makes risk stratification of patients challenging, the decision to initiate, change or stop treatment should be based on a combination of the current disease state and the speed of progression.

Efficacy and safety of nintedanib in Asian patients with systemic sclerosis-associated interstitial lung disease: Subgroup analysis of the SENSCIS trial. Respir Investig 2020; 59:252-259. [PMID: 33223487 DOI: 10.1016/j.resinv.2020.10.005] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Accepted: 10/14/2020] [Indexed: 11/19/2022]
Abstract
BACKGROUND AND OBJECTIVE In the SENSCIS trial in patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD), nintedanib reduced the rate of decline in forced vital capacity (FVC) (mL/year) over 52 weeks by 44% in comparison with placebo, with manageable adverse events in most patients. We analyzed the efficacy and safety of nintedanib in patients of Asian race. METHODS Patients with SSc-ILD were randomized to receive nintedanib or placebo. The outcomes over 52 weeks were analyzed in Asian versus non-Asian patients. RESULTS Of the 288 patients in each treatment group, 62 (21.5%) in the nintedanib group and 81 (28.1%) in the placebo group were Asian; 90.2% of the Asian patients were enrolled in Asian countries. In the placebo group, the rate of FVC decline over 52 weeks was consistent between Asian and non-Asian patients (-99.9 and -90.6 mL/year, respectively). The effect of nintedanib on reducing the rate of FVC decline over 52 weeks was consistent between Asian (difference, 44.3 mL/year [95% CI: -32.8, 121.4]) and non-Asian patients (difference, 39.0 mL/year [95% CI: -5.1, 83.1]) (treatment-by-time-by-subgroup interaction, p = 0.91). Diarrhea was the most frequent adverse event and was reported in similar proportions of Asian and non-Asian patients in the nintedanib group (80.6% and 74.3%, respectively) and placebo group (28.4% and 32.9%, respectively). CONCLUSIONS In patients with SSc-ILD, nintedanib had a consistent benefit on slowing the progression of SSc-ILD in Asian and non-Asian patients, with a similar adverse event profile.

Abstract
Background/Aims Our study aims to characterize esophageal motor function; evaluate the relationships among esophagogastroduodenoscopy (EGD), high-resolution manometry (HRM), and 24-hour esophageal multichannel intraluminal impedance monitoring combined with pH-metry (MII-pH); and elucidate the determinants of esophageal symptom perception in South Koreans with systemic sclerosis (SSc). Methods We reviewed prospectively collected HRM (n = 46), EGD (n = 41), and MII-pH (n = 37) data from 46 consecutive patients with SSc (42 females; mean age 50.1 years) who underwent esophageal tests between June 2013 and September 2018. Results The most common HRM diagnosis was normal (39.1%), followed by ineffective esophageal motility (23.9%) and absent contractility (21.7%). Erosive esophagitis was observed in 12.2% of total SSc patients, with a higher frequency in patients with absent contractility than those with normal motility (44.5% vs 0.0%, P = 0.01). Pathologic acid exposure was observed in 6 patients (20.0%) and positive symptom association in 18 patients (60.0%) in MII-pH tests of symptomatic patients. The proportion of SSc patients with esophageal symptoms not explained by reflux or mucosal or motor esophageal abnormalities was 33.0%. Conclusions Esophageal involvement among South Koreans with SSc was characterized by heterogeneous motility patterns, with a higher prevalence of normal motility and lower prevalence of erosive esophagitis. Reflux hypersensitivity or functional heartburn might be partly attributed to the perception of esophageal symptoms in SSc patients who have neither gastroesophageal reflux disease nor esophageal dysmotility.

Abstract
OBJECTIVE Systemic sclerosis (SSc) is a rare multisystem autoimmune disorder. It has a worldwide distribution but geographical and ethnic influences are poorly known. METHODS The aim of the study was to compare demographic characteristics and frequency of internal organ system involvement of Black SSc patients to those of White SSc patients in France. Patient population included 425 SSc patients recruited at Cochin Hospital in Internal medicine and Rheumatology departments. Data were collected at the baseline visit, each Black patient was matched with 2 to 3 White controls from the same department. RESULTS One hundred and five Black patients and 320 White were included. Demographic comparison highlighted an older age for the White patients (48.66±14.87 vs 39.56±10.79, P<0.0001). Phenotypic comparison showed more severe skin involvement for Black patients: they had more often diffuse skin involvement than White patients (69.2% vs. 44.7%, P<0.0001) with a higher baseline modified Rodnan skin score (15.8 vs. 11.3, P<0.001). Comparisons also showed more active ulcers (46.5% vs. 21.6%, P<0.001) and more common interstitial lung disease (73.7% vs. 43%, P<0.0001) for Black patients. Auto-antibody testing showed that White patients were more likely to harbor anti-centromere antibodies (ACA) (26.6% vs. 9%, P<0.001) whereas Black patients were more likely to have anti-U1RNP antibody (24.6% vs. 6.2%, P<0.0001). CONCLUSION In this population recruited in a disease referral center, Black patients had more severe skin and lung involvements with lower prevalence of ACA as compared to White patients, supporting a more severe phenotype.

Abstract
OBJECTIVES Racial factors play a significant role in SSc. We evaluated differences in SSc presentations between white patients (WP), Asian patients (AP) and black patients (BP) and analysed the effects of geographical locations. METHODS SSc characteristics of patients from the EUSTAR cohort were cross-sectionally compared across racial groups using survival and multiple logistic regression analyses. RESULTS The study included 9162 WP, 341 AP and 181 BP. AP developed the first non-RP feature faster than WP but slower than BP. AP were less frequently anti-centromere (ACA; odds ratio (OR) = 0.4, P < 0.001) and more frequently anti-topoisomerase-I autoantibodies (ATA) positive (OR = 1.2, P = 0.068), while BP were less likely to be ACA and ATA positive than were WP [OR(ACA) = 0.3, P < 0.001; OR(ATA) = 0.5, P = 0.020]. AP had less often (OR = 0.7, P = 0.06) and BP more often (OR = 2.7, P < 0.001) diffuse skin involvement than had WP. AP and BP were more likely to have pulmonary hypertension [OR(AP) = 2.6, P < 0.001; OR(BP) = 2.7, P = 0.03 vs WP] and a reduced forced vital capacity [OR(AP) = 2.5, P < 0.001; OR(BP) = 2.4, P < 0.004] than were WP. AP more often had an impaired diffusing capacity of the lung than had BP and WP [OR(AP vs BP) = 1.9, P = 0.038; OR(AP vs WP) = 2.4, P < 0.001]. After RP onset, AP and BP had a higher hazard to die than had WP [hazard ratio (HR) (AP) = 1.6, P = 0.011; HR(BP) = 2.1, P < 0.001]. CONCLUSION Compared with WP, and mostly independent of geographical location, AP have a faster and earlier disease onset with high prevalences of ATA, pulmonary hypertension and forced vital capacity impairment and higher mortality. BP had the fastest disease onset, a high prevalence of diffuse skin involvement and nominally the highest mortality.

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.

Abstract
Systemic sclerosis (SSc) is a systemic autoimmune disease affecting multiple organ systems, including the lungs. Interstitial lung disease (ILD) is the leading cause of death in SSc. There are no valid biomarkers to predict the occurrence of SSc-ILD, although auto-antibodies against anti-topoisomerase I and several inflammatory markers are candidate biomarkers that need further evaluation. Chest auscultation, presence of shortness of breath and pulmonary function testing are important diagnostic tools, but lack sensitivity to detect early ILD. Baseline screening with high-resolution computed tomography (HRCT) is therefore necessary to confirm an SSc-ILD diagnosis. Once diagnosed with SSc-ILD, patients' clinical courses are variable and difficult to predict, although certain patient characteristics and biomarkers are associated with disease progression. It is important to monitor patients with SSc-ILD for signs of disease progression, although there is no consensus about which diagnostic tools to use or how often monitoring should occur. In this article, we review methods used to define and predict disease progression in SSc-ILD. There is no valid definition of SSc-ILD disease progression, but we suggest that either a decline in forced vital capacity (FVC) from baseline of ≥10%, or a decline in FVC of 5–9% in association with a decline in diffusing capacity of the lung for carbon monoxide of ≥15% represents progression. An increase in the radiographic extent of ILD on HRCT imaging would also signify progression. A time period of 1–2 years is generally used for this definition, but a decline over a longer time period may also reflect clinically relevant disease progression. Lung function tests and chest imaging help predict who has SSc-associated ILD and whether it will progress. In the absence of standardised methods for doctors, we recommend a strategy that combines both lung function tests and chest imaging.http://bit.ly/2uK9ZD2

ACR Open Rheumatol 2020; 2:197-206. [PMID: 32198914 PMCID: PMC7164633 DOI: 10.1002/acr2.11126] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2019] [Accepted: 02/18/2020] [Indexed: 11/21/2022] Open
Abstract
Objective The objective of this study is to evaluate racial/ethnic differences in disease manifestations and survival in a US cohort of patients with systemic sclerosis (SSc), with a focus on Asian patients. Methods A retrospective cohort study was conducted among Kaiser Permanente Northern California adults with an incident SSc diagnosis by a rheumatologist from 2007 to 2016, confirmed by a chart review to fulfill 2013 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria. Self‐reported race/ethnicity was categorized as non‐Hispanic white, Asian, Hispanic, and black. Disease manifestations and survival were compared, using white patients as the reference. Results A total of 609 patients with incident SSc were identified: 89% were women, and 81% had limited cutaneous SSc, with a mean age at diagnosis of 55.4 ± 14.8 years. The racial/ethnic distribution was 51% non‐Hispanic white (n = 310), 25% Hispanic (n = 154), 16% Asian (n = 96), and 8% black (n = 49). Compared with white patients, black patients had a greater prevalence of diffuse disease (14.5% vs. 44.9%; P < 0.001), and Asians had higher rates of anti‐U1‐RNP antibodies (32.1% vs. 11.9%; P = 0.005). Nine‐year overall survival rates following SSc diagnosis were lower in Asian (52.3%), black (52.2%), and Hispanic patients (68.2%) compared with white patients (75.8%). Pulmonary hypertension and infections were the leading causes of death in Asian patients. Asian race was associated with higher mortality on univariable (hazard ratio [HR] 1.83 [95% confidence interval (CI) 1.08‐2.99]; P = 0.020) and multivariable analyses (HR 1.80 [95% CI 0.99‐3.16]; P = 0.047) when adjusting for age, sex, body mass index, cutaneous subtype, smoking status, interstitial lung disease, pulmonary hypertension, renal crisis, and malabsorption syndrome. Conclusion Asian patients with SSc in this US cohort had increased mortality compared with white patients. These patients warrant close monitoring for disease progression.

Abstract
A subgroup of patients with systemic sclerosis (SSc) develop interstitial lung disease (ILD), characterized by inflammation and progressive scarring of the lungs that can lead to respiratory failure. Although ILD remains the major cause of death in these individuals, there is no consensus statement regarding the classification and characterization of SSc-related ILD (SSc-ILD). Recent clinical trials address the treatment of SSc-ILD and the results may lead to new disease-altering therapies. In this review, we provide an update to the diagnosis, management and treatment of SSc-ILD.
