We validated psychometric properties of the scale with 70 consecutive systemic sclerosis (SSc) patients, who fulfilled the 2013 ACR/EULAR classification criteria for SSc.
Systemic features and a strongly positive anticentromere antibody led to the diagnosis of limited cutaneous SSc with a score of 12 on the ACR/EULAR criteria.
The summed DSS score and the general, skin and gastrointestinal tract DSS scores were significantly lower in early SSc than in the historical group.<b>Conclusion:</b> SSc patients with a diagnosis after the new ACR/EULAR criteria development were diagnosed earlier and had a less severe disease than historical patients.
To determine whether angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism is associated with the development and clinical features of systemic sclerosis (SSc) in Korean, we studied seventy two Korean patients with SSc fulfilling the ACR preliminary classification criteria.
This prospective, longitudinal cohort study recruited 68 consecutive SSc patients (group #1: 32 established disease (ACR, American College of Rheumatology /EULAR, The European League against Rheumatism 2013 and ACR 1980 criteria fulfilled); group #2: 24 early disease (only ACR/EULAR 2013 fulfilled); group #3: 12 very early disease (clinical expert diagnosis of SSc) and 72 healthy controls.
Targeting the myofibroblast genetic switch: inhibitors of myocardin-related transcription factor/serum response factor-regulated gene transcription prevent fibrosis in a murine model of skin injury.
We have shown that impairment of actin assembly as a result of desmoglein-2/integrin-beta8 complex formation is a major factor contributing to angiogenesis deregulation in Systemic sclerosis.
Confocal microscopy identified cells displaying simultaneous expression of von Willebrand factor and α-smooth muscle actin in small and medium-sized arterioles in the SSc lung tissue but not in normal control lungs.
The reduced angiogenic properties of SSc MVECs can be explained by the effects of uPAR truncation and the subsequent loss of the beta2 integrin-mediated connection of uPAR with the actin cytoskeleton in these ECs.
After sorting, we showed: i. an increased production of vascular endothelial growth factor A (VEGF-A) in SSc-MSCs when co-cultured with SSc-ECs; ii. an increased level of transforming growth factor beta (TGF-β) and platelet growth factor BB (PDGF-BB) in SSc-ECs when co-cultured with both HC- and SSc-MSCs; iii. an increase of TGF-β, PDGF-R, alpha smooth muscle actin (α-SMA) and collagen 1 (Col1) in both HC- and SSc-MSCs when co-cultured with SSc-ECs.
FPR stimulation promoted α-smooth muscle actin expression in normal fibroblasts as well as motility, matrix deposition, αvβ5 integrin expression, and radical oxygen species generation in normal and SSc fibroblasts.
Selexipag and mainly its active metabolite ACT-333679 were found for the first time to potentially interfere with the profibrotic activity of cultured SSc fibroblasts/myofibroblasts at least in vitro, possibly through the downregulation of fibrogenic Erk1/2 and Akt signaling molecules.

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.
