OBJECTIVES To determine the causes and predictors of mortality in systemic sclerosis (SSc). METHODS Patients with SSc (n=5860) fulfilling the American College of Rheumatology criteria and prospectively followed in the EULAR Scleroderma Trials and Research (EUSTAR) cohort were analysed. EUSTAR centres completed a structured questionnaire on cause of death(More)
Free radical-mediated oxidative stress has been implicated in the etiopathogenesis of several autoimmune disorders. We investigated the prooxidant-antioxidant status in order to evaluate the possible deleterious role of oxidative phenomena in patients with Graves' disease. Thirty patients with hyperthyroidism due to Graves' disease were investigated. Thirty(More)
Ghrelin is a gastric hormone that posses multiple functions, including induction of growth hormone release, regulation of proinflammatory cytokines and control of food intake and energy homeostasis. A few reports on serum ghrelin level in chronic inflammatory states revealed contradictory results. The study was undertaken to determine ghrelin in patients(More)
Human cartilage glycoprotein-39 (HC gp-30) is a secretory protein of several types of cells including chondrocytes. It has been suggested to be a laboratory index of joint damage. Thirty-two patients with systemic sclerosis (SSc) and 22 age-matched controls were investigated. An increased serum HC gp-39 level was shown in SSc patients and was found to(More)
Serum leptin levels were determined in 31 women with systemic sclerosis and 24 age-matched healthy controls. Both groups were divided into premenopausal and postmenopausal subgroups. A decreased serum leptin was found in the patients with systemic sclerosis. The premenopausal patients and controls had higher serum leptin than those in the postmenopausal(More)
TNF-α is one of the key proinflammatory cytokines in pathogenesis of rheumatoid arthritis (RA). TNF-α was also found to enhance synthesis of leptin. Leptin is mainly adipocyte-derived hormone controlling appetite and energy expenditure. It acts through inhibition of neuropeptide Y secretion. It is possible that TNF-α-induced leptin secretion contributes to(More)
Central nervous system involvement is seldom reported in patients with systemic sclerosis (SSc). Cognitive functions were determined in 21 patients with definite SSc and 42 healthy controls. Thyroid function was also measured in order to eliminate the effect of hypothyroidism on cognitive functioning. It was found that the SSc patients with normal thyroid(More)
BACKGROUND Qualitative and quantitative evaluation of plasma glycosaminoglycans (GAGs) of rheumatoid arthritis (RA) patients in relation to disease activity estimated by DAS28 score was evaluated. METHODS GAGs were quantified by hexuronic acid assay and electrophoretic fractionation. Keratan sulfate (KS) and hyaluronic acid (HA) were measured by(More)
