Various haemostatic abnormalities have been associated with thyroid dysfunction, especially with hypothyroidism. The underlying mechanisms are not well established.The aim of the study was to evaluate the primary and secondary haemostasis in patients with severe hypothyroidism, to assess the role of thyroid hormone deficiency and to determine whether increased serum TSH level despite normal free thyroid hormone concentrations could influence the coagulat...

Introduction: Thyrotropin receptor stimulating antibodies (TRAb) are responsible for Graves’ disease (GD) manifestations. Other thyroid antibodies, namely thyroperoxidase (TPOAb) and thyroglobulin (TGAb) antibodies are highly prevalent in GD, but their roles in GD presentation and evolution are controversial.Methods: We retrospectively analysed TPOAb and TGAb levels and evolution in 88 consecutive patients with newly diagnosed GD between 2000 and 20...

As known, an imbalance of the gut microbiota is associated with a higher risk for autoimmune diseases. Moreover the increased rates of autoimmunity reported in urban residential areas worldwide suggest a possible influence of diet. We report on the antibody response to food antigens in GD patients. Since 10% of celiac patients develop an autoimmune thyreopathy we focused on gliadin (DGP), transglutaminases (tTG) and 40 other food antigens (FA). Commercially available ELISA ass...

Caveolin-1 (cav1) is a member of the thyroxisome multiprotein complex required for thyroid hormones synthesis which is decreased in Hashimoto’s thyroiditis (HT) and excessive in Graves’ disease (GD). Both pathologies are characterized by oxidative stress (OS), the production of reactive oxygen species (ROS) exceeding the antioxidant defenses. The aim of this study is to correlate cav1 expression and OS in HT and GD. Primary cultures of human thyrocytes were treated o...
