OBJECTIVES Ischaemic digital ulcers (DUs) are common in patients with systemic sclerosis (SSc) and are a cause of disease-related morbidity. In an earlier trial, treatment with bosentan, an oral endothelin receptor antagonist, reduced the occurrence of new DUs by 48%. The present study (RAPIDS-2, for 'RAndomized, double-blind, Placebo-controlled study with(More)
BACKGROUND We conducted a double-blind, randomized, placebo-controlled trial to determine the effects of oral cyclophosphamide on lung function and health-related symptoms in patients with evidence of active alveolitis and scleroderma-related interstitial lung disease. METHODS At 13 clinical centers throughout the United States, we enrolled 158 patients(More)
Systemic sclerosis (SSc) is an autoimmune disease characterized by fibrosis of the skin and internal organs that leads to profound disability and premature death. To identify new SSc susceptibility loci, we conducted the first genome-wide association study in a population of European ancestry including a total of 2,296 individuals with SSc and 5,171(More)
BACKGROUND Systemic sclerosis (SSc) is characterized by excessive fibrosis and obliterative vascular lesions. Abnormal TGFbeta activation is implicated in the pathogenesis of SSc. Aberrant TGFbeta/Smad signaling can be controlled by stabilization of microtubules with paclitaxel. METHODS AND FINDINGS SSc and healthy human skin biopsies were incubated in(More)
The observation that revelation of immunocryptic epitopes in self antigens may initiate the autoimmune response has prompted the search for processes which induce novel fragmentation of autoantigens as potential initiators of autoimmunity. The reversible ischemia reperfusion which characterizes scleroderma has focused attention on reactive oxygen species as(More)
In systemic sclerosis (SSc), a common and aetiologically mysterious form of scleroderma (defined as pathological fibrosis of the skin), previously healthy adults acquire fibrosis of the skin and viscera in association with autoantibodies. Familial recurrence is extremely rare and causal genes have not been identified. Although the onset of fibrosis in SSc(More)
Body image dissatisfaction and its relationship to psychosocial function were investigated in 127 women with scleroderma Results indicated elevated body image dissatisfaction, with participants reporting higher levels than a sample of patients with severe burn injuries. Age, skin tightening above the elbows, and functional disability were related to(More)
Diseases such as autism, cardiovascular disease, and the au-toimmune disorders are difficult to treat because of the remarkable degree of variation among affected individuals. Subtyping research seeks to refine the definition of such complex , multi-organ diseases by identifying homogeneous patient subgroups. In this paper, we propose the Probabilis-tic(More)
Autoimmune diseases are thought to be initiated by exposures to foreign antigens that cross-react with endogenous molecules. Scleroderma is an autoimmune connective tissue disease in which patients make antibodies to a limited group of autoantigens, including RPC1, encoded by the POLR3A gene. As patients with scleroderma and antibodies against RPC1 are at(More)
OBJECTIVE Pain and body image distress are common among women with SSc, but their relative associations with reduced sexual function have not been assessed. The objective of this study was to assess the independent associations of pain and body image distress with reduced sexual function in women with SSc. METHODS Female SSc patients completed measures of(More)
