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.

Performance Characteristics of Pulmonary Function Tests for the Detection of Interstitial Lung Disease in Adults With Early Diffuse Cutaneous Systemic Sclerosis.

Objective: Interstitial lung disease (ILD) is the leading cause of death in patients with systemic sclerosis (SSc). Although pulmonary function tests (PFTs) are commonly used to screen for ILD in patients with SSc, studies have shown that they lack sensitivity for the detection of ILD in general SSc cohorts. This study was undertaken to assess the performance characteristics of PFTs for the detection of ILD in patients with early diffuse cutaneous SSc (dcSSc), a population at high risk for the development of ILD.

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.

Objective: To determine the inter/intraobserver reliability of the tender and swollen joint counts (TJC, SJC) and the modified Rodnan Skin Score (mRSS) in diffuse cutaneous systemic sclerosis (dcSSc) and to assess content validity of the TJC/SJC.

Methods: Ten rheumatologists completed the SJC, TJC, and mRSS on 7 patients. Musculoskeletal ultrasound (MSUS) was performed.

Systemic Sclerosis and Perceptions of Quality in Primary Care.

Background: Among patients with systemic sclerosis (SSc), early recognition of potentially life-threatening organ involvement is critical. Because prompt recognition of early signs of organ involvement can dramatically alter a patient׳s outcome, it is crucial that patients and primary care providers (PCPs) recognize these symptoms. We conducted a survey of patients with SSc regarding their perceptions of the quality of their primary care, and whether or not they perceive the quality of their primary care to be impaired by their scleroderma diagnosis.

Drugs that may harm bone: Mitigating the risk.

Glucocorticoids, proton pump inhibitors, selective serotonin reuptake inhibitors (SSRIs), certain antiepileptic drugs, and aromatase inhibitors have significant adverse effects on bone. Healthcare providers should monitor the bone health of patients on these agents, supplement their intake of calcium and vitamin D, encourage weight-bearing exercise, and initiate osteoporosis-prevention treatment as indicated.

Treatment of early diffuse systemic sclerosis skin disease.

Diffuse systemic sclerosis carries a high morbidity and mortality. The Prospective Registry of Early Systemic Sclerosis (PRESS), a multicentre incident cohort study of patients with early diffuse cutaneous systemic sclerosis, has the goal of advancing the understanding of disease pathogenesis and identifying novel biomarkers. In this review, PRESS investigators discuss the evidence pertaining to the more commonly used treatments for early diffuse SSc skin disease including methotrexate, mycophenolate, cyclophosphamide, azathioprine, and intravenous immunoglobulin.

Imaging of scleroderma.

Systemic sclerosis is a rare autoimmune condition that affects a variety of organ systems. Knowledge of the imaging features in this patient population is essential in facilitating accurate diagnosis and guiding treatment. Common and rare imaging features of systemic sclerosis are reviewed in this article.

Elevated expression of cav-1 in a subset of SSc fibroblasts contributes to constitutive Alk1/Smad1 activation.

Previous studies have shown that the transforming growth factor (TGF)β/Alk1/Smad1 signaling pathway is constitutively activated in a subset of systemic sclerosis (SSc) fibroblasts and this pathway is a critical regulator of CCN2 gene expression. Caveolin-1 (cav-1), an integral membrane protein and the main component of caveolae, has also been implicated in SSc pathogenesis. This study was undertaken to evaluate the role of caveolin-1 in Smad1 signaling and CCN2 expression in healthy and SSc dermal fibroblasts.

Autocrine transforming growth factor β signaling regulates extracellular signal-regulated kinase 1/2 phosphorylation via modulation of protein phosphatase 2A expression in scleroderma fibroblasts.

Background: During scleroderma (SSc) pathogenesis, fibroblasts acquire an activated phenotype characterized by enhanced production of extracellular matrix (ECM) and constitutive activation of several major signaling pathways including extracellular signal-related kinase (ERK1/2). Several studies have addressed the role of ERK1/2 in SSc fibrosis however the mechanism of its prolonged activation in SSc fibroblasts is still unknown. Protein phosphatase 2A (PP2A) is a key serine threonine phosphatase responsible for dephosphorylation of a wide array of signaling molecules.

Biomarkers of scleroderma lung disease: recent progress.

This article reviews the clinical background and significance of selected biomarkers that have been studied in relation to systemic sclerosis, or scleroderma, a devastating connective tissue disease whose morbidity and mortality are often related to pulmonary complications. Interstitial lung disease is the most common pulmonary manifestation in systemic sclerosis, and the search for a noninvasive biomarker to assess and monitor patients and their lung disease is a nascent and expending field of study. In this article, we examine the background and significance of a variety of selected biomarkers and assess their role in relation to systemic sclerosis–related interstitial lung disease.
