Hand Swelling and Other Non-Raynaud Phenomenon Symptoms as the Initial Presentation of Systemic Sclerosis: Prevalence and Clinical Associations in Two US Cohorts.

Objective: Raynaud phenomenon (RP) is often the initial clinical manifestation of systemic sclerosis (SSc), but some patients develop other manifestations first. To help elucidate the diversity of SSc presentation in its early stages, we describe the initial clinical manifestations and antinuclear antibody (ANA) profiles of patients in two early SSc cohorts.

Methods: All patient data in the Genetics vs Environment in Scleroderma Outcomes Study (GENISOS) and Collaborative National Quality and Efficacy Registry (CONQUER) cohorts were reviewed.

Serum type I interferon score as a disease activity biomarker in patients with diffuse cutaneous systemic sclerosis: a retrospective cohort study.

Background: Type I interferon (IFN) pathway activation has been associated with severe systemic sclerosis. We aimed to examine the association of serum IFN scores with disease activity and outcomes in two cohorts of patients with diffuse cutaneous systemic sclerosis.

Methods: In this retrospective cohort study, we included adult (aged >18 years) patients with diffuse cutaneous systemic sclerosis enrolled in the US Prospective Registry of Early Systemic Sclerosis (PRESS; incident cohort) or in the UK observational cohort (Stratification for Risk of Progression in Scleroderma [STRIKE]; prevalent cohort) registries and healthy controls (volunteers).

Belumosudil in diffuse cutaneous systemic sclerosis: a randomized, double-blind, open-label extension, placebo-controlled, phase 2 study.

Objectives: To determine the efficacy, safety and pharmacodynamics of belumosudil in patients with diffuse cutaneous systemic sclerosis (dcSSc) treated with background immunosuppressive therapies.

Methods: Eligible patients were randomised 1:1:1 to receive belumosudil 200 mg once daily (QD) or twice daily (BID), or placebo for 28 weeks (double-blind period). After unblinding, the patients who received belumosudil continued the same dose, whereas the patients who received placebo were re-randomised for one of the belumosudil doses for 24 weeks (open-label extension).

Potential of phosphodiesterase 4B inhibitors in the treatment of interstitial lung disease associated with autoimmune diseases.

Patients with autoimmune disease-related interstitial lung disease may develop pulmonary fibrosis, which may become progressive. Progressive pulmonary fibrosis (PPF) is associated with poor outcomes. Antifibrotic therapies have shown efficacy as treatments for PPF in patients with autoimmune diseases, but new treatments are needed to slow or halt disease progression.

Clinically Recognized Depression and Mental Health Treatment in a Single Center Cohort of Patients with Systemic Sclerosis.

Introduction: In this study, we investigated the prevalence of depression, depression treatment, and symptom burden in patients with systemic sclerosis (SSc) and examined their associations with the center for epidemiologic studies depression scale revised (CESD-R) scores.

Methods: The Prospective Registry in Scleroderma at Massachusetts General Hospital (PRISM) is a longitudinal registry of patients with SSc. Among participants with CESD-R score ≥ 16, indicating possible depression, a chart review was performed for mental health diagnoses and treatments.

The Collaborative National Quality and Efficacy Registry for Scleroderma: association of medication use on gastrointestinal tract symptoms in early disease and the importance of tobacco cessation.

Objectives: Systemic Sclerosis (SSc) is frequently associated with gastrointestinal tract (GIT) involvement. The Collaborative National Quality and Efficacy Registry (CONQUER) is a US-based collaborative study collecting longitudinal follow up data on SSc patients with less than 5-years disease duration enrolled at Scleroderma centres of excellence. This manuscript presents the GIT natural history and outcomes in relation to other scleroderma manifestations and medication exposures.

E-Cigarette Use, Small Airway Fibrosis, and Constrictive Bronchiolitis.

Background: Vaping, including the use of electronic cigarettes (e-cigarettes), has become increasingly prevalent, yet the associated long-term health risks are largely unknown. Given the prevalence of use, particularly among adolescents early in their lifespan, it is vital to understand the potential chronic pathologic sequelae of vaping.

Methods: We present the cases of four patients with chronic lung disease associated with e-cigarette use characterized by clinical evaluation, with pulmonary function tests (PFTs), chest high-resolution computed tomography (HRCT), endobronchial optical coherence tomography (EB-OCT) imaging, and histopathologic assessment.

CONQUER Scleroderma: association of gastrointestinal tract symptoms in early disease with resource utilization.

Objectives: SSc is associated with increased health-care resource utilization and economic burden. The Collaborative National Quality and Efficacy Registry (CONQUER) is a US-based collaborative that collects longitudinal follow-up data on SSc patients with <5 years of disease duration enrolled at scleroderma centres in the USA. The objective of this study was to investigate the relationship between gastrointestinal tract symptoms and self-reported resource utilization in CONQUER participants.

Pulmonary Hypertension: How to Best Treat the Different Scleroderma Phenotypes?

Pulmonary hypertension (PH) is a leading cause of morbidity and mortality in systemic sclerosis (SSc). PH is a heterogenous condition and several different forms of PH are associated with SSc, including pulmonary arterial hypertension (PAH) resulting from a pulmonary arterial vasculopathy, PH due to interstitial lung disease, PH due to left heart disease, and PH due to thromboembolic disease. Extensive research has led to an improved understanding of the mediators involved in the pathogenesis of SSc-PH.

Expert consensus on the management of systemic sclerosis-associated interstitial lung disease.

Background: Systemic sclerosis (SSc) is a rare, complex, connective tissue disorder. Interstitial lung disease (ILD) is common in SSc, occurring in 35-52% of patients and accounting for 20-40% of mortality. Evolution of therapeutic options has resulted in a lack of consensus on how to manage this condition.

Computed Tomography of the Chest to Screen for Interstitial Lung Disease in Patients With Systemic Sclerosis at Expert Scleroderma Centers in the United States.

Objective: Although a high-resolution computed tomography (HRCT) scan of the chest is the gold standard test for the detection of interstitial lung disease (ILD), there is no consensus among rheumatologists regarding the use of HRCT to screen for ILD in their patients with systemic sclerosis (SSc). The aims of this study were to describe the HRCT ordering practices at SSc centers in the United States and to determine which patient characteristics are associated with HRCT performance.

Methods: We performed a prospective cohort study of patients with SSc enrolled in the US-based Collaborative National Quality and Efficacy Registry (CONQUER).

The Association of Illness-related Uncertainty With Mental Health in Systemic Autoimmune Rheumatic Diseases.

Objective: Patients with systemic autoimmune rheumatic diseases (SARDs) face illness-related uncertainty, but little is known about the psychological profiles and psychosocial and health needs associated with uncertainty among adults with SARDs.

Methods: Patients from the Massachusetts General Hospital with antineutrophil cytoplasmic antibody-associated vasculitis (AAV), IgG4-related disease (IgG4-RD), and systemic sclerosis (SSc) completed the Mishel Uncertainty in Illness Scale, 8-item Patient Health Questionnaire depression scale, 7-item General Anxiety Disorder scale, Sickness Impact Profile, and a survey of psychosocial needs. The associations of uncertainty and self-reported needs with depression, anxiety, and sickness impact were assessed.

Change in calcinosis over 1 year using the scleroderma clinical trials consortium radiologic scoring system for calcinosis of the hands in patients with systemic sclerosis.

Introduction: Calcinosis cutis is a debilitating complication of systemic sclerosis (SSc). We previously developed a radiographic scoring system to assess severity of calcinosis affecting the hands in patients with SSc. We sought to further validate our radiographic scoring system to assess for change over 1 year and to identify factors associated with improvement or progression.

Baseline characteristics of systemic sclerosis patients with restrictive lung disease in a multi-center US-based longitudinal registry.

Aim: Interstitial lung disease (ILD) is the leading cause of disease-related death in systemic sclerosis (SSc). Here, we assess baseline characteristics of SSc subjects with and without restrictive lung disease (RLD) in a multi-center, US-based registry.

Methods: SSc patients within 5 years of disease onset were enrolled in the Collaborative National Quality and Efficacy Registry (CONQUER), a multi-center US-based registry of SSc study participants (age ≥ 18 years) enrolled at 13 expert centers.

Rituximab for interstitial pneumonia with autoimmune features at two medical centres.

Objectives: Many patients with interstitial lung disease (ILD) have autoimmune manifestations but do not meet criteria for a systemic rheumatic disease. A subset meets criteria for interstitial pneumonia with autoimmune features (IPAF) and have ILD requiring therapy. We conducted a multicentre observational study to examine the use of rituximab (RTX) in IPAF.

Clinical characteristics, visceral involvement, and mortality in at-risk or early diffuse systemic sclerosis: a longitudinal analysis of an observational prospective multicenter US cohort.

Background: Early diffuse cutaneous systemic sclerosis (dcSSc) has the highest case fatality among rheumatic diseases. We report baseline characteristics, current immunosuppressive therapies, progression of skin and internal organ involvement, and mortality in a multicenter prospective cohort from the United States (US) of America.

Methods: We performed a longitudinal analysis of participants from 12 US centers, from April 2012 to July 2020.

Detection and Management of Interstitial Lung Diseases Associated With Connective Tissue Diseases.

Interstitial lung disease (ILD) is a common manifestation of connective tissue diseases (CTDs). A proportion of patients with CTD-ILDs develop progressive fibrosing ILD, which is characterized by worsening fibrotic abnormalities on high-resolution computed tomography scan, decline in lung function, worsening symptoms, and early mortality. Here, we review the impact of ILD in patients with CTDs, the importance of prompt diagnosis and close monitoring, and the evidence available to guide the management of CTD-ILDs.

Predictive Significance of Serum Interferon-Inducible Protein Score for Response to Treatment in Systemic Sclerosis-Related Interstitial Lung Disease.

Objective: Response to immunosuppression is highly variable in systemic sclerosis (SSc)-related interstitial lung disease (ILD). This study was undertaken to determine whether a composite serum interferon (IFN)-inducible protein score exhibits predictive significance for the response to immunosuppression in SSc-ILD.

Methods: Serum samples collected in the Scleroderma Lung Study II, a randomized controlled trial of mycophenolate mofetil (MMF) versus cyclophosphamide (CYC), were examined.

Does hand involvement in systemic sclerosis limit completion of patient-reported outcome measures?

The objective of this analysis is to examine whether the severity of systemic sclerosis (SSc)-hand involvement influences patient-reported outcome measure (PROM) completion rate in a US cohort of early disease. Participants included SSc patients with less than 5 years disease duration consented and enrolled in the Collaborative, National, Quality, and Efficacy Registry (CONQUER) between June 2018 and December 2019. Participants' socio-demographics, hand clinical features (severe modified Rodnan skin score, presence of small joint contractures, acro-osteolysis, calcinosis, and digital ulcers), and completion rates of seven PROMs including a Resource Use Questionnaire were analyzed.

Calcinosis is associated with ischemic manifestations and increased disability in patients with systemic sclerosis.

Objective: Calcinosis is a debilitating complication of systemic sclerosis (SSc) with no effective treatments. We sought to identify clinical correlations and to characterize complications and disability associated with calcinosis in a multi-center, international cohort of SSc patients.

Methods: We established a cohort of 568 consecutive SSc patients who fulfill 2013 revised ACR/EULAR criteria at 10 centers within North America, Australia, and Mexico.

Global skin gene expression analysis of early diffuse cutaneous systemic sclerosis shows a prominent innate and adaptive inflammatory profile.

Objectives: Determine global skin transcriptome patterns of early diffuse systemic sclerosis (SSc) and how they differ from later disease.

Methods: Skin biopsy RNA from 48 patients in the Prospective Registry for Early Systemic Sclerosis (PRESS) cohort (mean disease duration 1.3 years) and 33 matched healthy controls was examined by next-generation RNA sequencing.

Collaborative National Quality and Efficacy Registry (CONQUER) for Scleroderma: outcomes from a multicenter US-based systemic sclerosis registry.

The Collaborative National Quality and Efficacy Registry (CONQUER) for Scleroderma is a multicenter US-based longitudinal study of patients with systemic sclerosis (SSc) within 5 years of first non-Raynaud's symptom. The data collection methodology incorporates successful models from other SSc registries. The cohort is designed to provide linked bio-specimen and clinical outcomes data on a longitudinal cohort of SSc patients for validation of hypothesis-driven research and to provide a platform for studying patient-reported outcomes in scleroderma.
