BACKGROUND Thyroid function abnormalities and thyroid autoantibodies have been frequently described in patients with systemic autoimmune diseases as systemic sclerosis (SSc). Serum TSH levels are higher in SSc patients with more severe skin diseases and a worse modified Rodnan skin score. Asymptomatic esophageal involvement due to SSc has never been described as a cause of severe hypothyroidism...

Hypoxia may play an important role in the pathogenesis of systemic sclerosis (SSc). Carbonic anhydrase IX (CA IX) is one of the hypoxia markers and its extracellular domain can be released into the serum. However, the clinical significance of serum CA IX levels in SSc is still unknown. The aim of this study is to evaluate the possibility that serum CA IX levels can be a specific disease marker ...

BACKGROUND Dermal fibroblasts from patients with systemic sclerosis (SSc) release excessive amounts of collagen resulting in tissue fibrosis. The molecular mechanisms underlying this pathological activation are incompletely understood. OBJECTIVE To investigate whether Notch signalling contributes to the uncontrolled activation of fibroblasts in SSc. METHODS Activation of the Notch pathway w...

Aging is a common risk factor of many disorders. With age, the level of insoluble extracellular matrix increases leading to increased stiffness of a number of tissues. Matrix accumulation can also be observed in fibrotic disorders, such as systemic sclerosis (SSc). Although the intrinsic aging process in skin is phenotypically distinct from SSc, here we demonstrate similar behavior of aged and ...

Microvascular disease is a prominent feature of systemic sclerosis (SSc) and leads to Raynaud's phenomenon, pulmonary arterial hypertension, and scleroderma renal crisis. The presence of macrovascular disease is less well established, and, in particular, it is not known whether the prevalence of coronary heart disease in SSc is increased. Furthermore, in terms of cardiac involvement in SSc, the...

OBJECTIVES To evaluate the performance of the 2013 ACR/EULAR classification criteria for systemic sclerosis (SSc) in clinical practice in a Chinese patient cohort, and to compare outcomes with the 1980 ACR criteria. METHODS Patients clinically diagnosed with SSc between September 2013 and May 2015 were prospectively recruited from the EUSTAR database of the Peking Union Medical College Hospit...

OBJECTIVES We aimed to investigate the contemporary usage rate and habits of the WHO Surgical Safety Checklist (SSC) in German urological departments. METHODS We designed a 26-item questionnaire that was sent to all urological departments in Germany. The primary aim of this study was to evaluate the usage rate of the SSC. Secondary aims were to compare perioperative characteristics of users v...

OBJECTIVES To assess the manifestations of systemic sclerosis (SSc), with an emphasis on the analysis of autoantibodies and their clinical correlations, in a population of patients followed up at the SSc Outpatient Clinics of the Hospital de Clínicas of the Universidade Federal do Paraná. METHODOLOGY Cross-sectional study with 96 patients followed up at the SSc Outpatient Clinics of the hospi...

Diffuse systemic sclerosis (SSc) is a chronic disease of unknown cause characterized by diffuse fibrosis and vascular abnormalities in the skin and internal organs. Pathogenesis of SSc involves immunologic mechanisms, vascular damage and activation of fibroblasts. SSc varies in severity and progression; most patients eventually develop visceral complications, which are the usual causes of death...

Lack of an adequate experimental model has hindered the ability to fully understand scleroderma (SSc) pathogenesis. Current SSc research is based on the study of cultured fibroblasts from skin biopsies. In depth characterization of the SSc fibroblast phenotype is hindered by the limited lifespan and heterogeneity of these cells. The goal of this study was to isolate high collagen-producing fibr...
