Objectives: Thyroid eye disease (TED) is considered a fibroinflammatory disease with pathology related to both inflammatory and fibrotic disease processes. IL-11 is a fibroinflammatory cytokine that is linked to tissue fibrosis of the lung, skin, heart, kidney and liver. Recently, IL-11 was identified as a possible disease modifier in TED. IL-11 levels are increased in TED patient plasma, in correlation with disease severity, and IL-11 stimulates phenotypic switching of orbita...

Introduction: Iodine is essential for thyroid funciton and severe deficiency adversely affects the developing brain. A raised and sufficient intake is particularly important during the pregnancy. Iodine sources include sea foods and sea salt, and it is available as a dietary supplement. The former was previously important to the Faroses diet but the intake of traditional Faroses foods is decreasing with at likely parallel influence on the iodine intake. Currently, there is no ...

Introduction: An increase in dietary iodine uptake, from insufficient to borderline values, induces the unmasking of a hidden epitope on thyroglobulin (Tg). No data about the effect of an excessive iodine intake on the expression of Tg epitopes recognized by human TgAb are available.Objective: To compare the expression of TgAb epitopes in sera of Hashimoto’s thyroiditis (HT) patients from areas with adequate, slightly and markedly excessive iodine i...

Ample literature exists on thyroid functioning and adjustments in Iodine-sufficient pregnant women. But information from endemic-iodine zones is meagre. In this study we attempt to understand how the thyroid copes with the dual challenge of iodine deficiency posed by physiological status of pregnancy and that by Iodine-deficient environment.Objective: To compare TSH and FT4 profiles and their mutual correlation in iodine-deficient and iodine-sufficient s...

Thyroid hormones influence other organs as well as nearly all parts of the human body, so thyroid hormone imbalance can cause diverse problems in the human body. Chronic rhinosinusitis (CRS) is one of the most common diseases among patients visiting otorhinolaryngology clinics, and CRS can be divided into two different subtypes: CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). CRS and thyroiditis are common diseases related to autoimmune features; however,...

Background: It is well established that during pregnancy, normal physiological changes occur concomitant with an enhanced metabolic demand for thyroxine/iodine. If dietary iodine intake is sufficient, normal equilibrium is achieved. With deficient iodine intake, the demand not being met, it is believed that pathological alterations occur leading to maternal thyroxineaemia and impaired growth and neurodevelopmental disorders in the offspring. However, there are very few studies...

Objectives: The interaction between genetic predisposing factors and environmental triggers is crucial for the development of HT. In last decades, the steady rise in frequency of HT in developed countries pointed to a strong influence of changing environmental factors, including increased pollution. Air pollutants, like dioxins and polycyclic aromatic hydrocarbons, are ligands of the aryl hydrocarbon receptor (AHR). This ligand-activated transcription factor, involved in pollu...

Objectives: SARS CoV-2 infections have been associated with the onset of classic subacute thyroiditis (SAT) or atypical SAT, observed in 10-15% of patients hospitalized for severe COVID19 disease (COV-A-SAT) and characterized by absence of neck pain, mild thyrotoxicosis associated with non-thyroidal illness syndrome and thyroiditis-like areas which may persist in the thyroid gland up to 12 months following SARS-CoV-2 infection, despite normalization of thyroid function. Little...

Objectives: In Graves’ disease (GD) and Graves’ orbitopathy (GO) self-reactive lymphocytes escape immune tolerance, although the underlying mechanisms are not fully understood. We aimed to characterize the immune signatures of target tissue-resident lymphocytes in relation to GD and GO.Methods: Lymphocytes were derived from blood and ultrasound-guided-fine-needle aspiration (US-FNA) of thyroid and neck lymph nodes (LNs) of the following patient...
