Introduction: B lymphocyte activating factor (BAFF), a member of the tumour necrosis factor family, is essential for B cell activation, differentiation and survival. It promotes autoantibody production and as Graves’ disease is caused by thyroid stimulating autoantibodies, it is an excellent functional candidate gene. Indeed, elevated serum BAFF levels have been found in patients with several autoimmune diseases, including Graves’ disease (GD). The T al...

Introduction: Iodine is important for thyroid hormone synthesis, and iodine deficiency in pregnancy may impair foetal neurological development. Perchlorate, found in some foods and everyday chemicals (e.g. fertilisers) and thiocyanate, which is found in cigarette smoke, decrease the transport of iodine from the circulation to the thyroid cells by inhibiting the sodium-iodide symporter. Environmental exposure to these substances during pregnancy may result in reduced thyroid ho...

Background: Autoimmune Addison’s disease (AAD) is a rare endocrinopathy arising from a complex interplay between multiple genetic susceptibility polymorphisms and environmental factors. Several variants in immune pathways have been identified through hypothesis-driven candidate gene analysis, though these associations can prove difficult to replicate. The first genome wide association study (GWAS) with patients from Scandinavian Addison’s registries identified associ...

Background: Prevalence of Addison’s disease (AD) among patients with Type 1 diabetes mellitus (T1DM) is estimated at 0.2%, whilst prevalence of T1DM among patients with AD can be up to 14%. Residual adrenal function in patients with established AD may be present in up to 30% of cases but its clinical significance is not fully clear.Aims: To evaluate the prevalence of AD with preserved glucocorticoid function in patients with T1DM at Newcastle Diabet...

Background: Iodine deficiency and excess are well-recognized risk factors for thyroid dysfunction. This systematic reveiw and meta-analysis was designed, for the first time, to explore whether maternal iodine status or supplementation is associated with postpartum thyroid function.Methods: Electronic databases, including the MEDLINE/PubMed, Web of Science, Embase, and Scopus were searched between January 1923 and December 2021 to identify relevant studie...

Introduction: Carcinoid Heart Disease (CHD) can occur in up to 50% of patients with long standing carcinoid syndrome as a result of metastatic neuroendocrine tumour (NET). It is associated with poor prognosis due to the development of right side heart failure. High circulating levels of serotonin cause cardiac fibrosis leading to tricuspid and pulmonary valve regurgitation and poor ventricular function. Cardiac surgery with valve replacement in combination with cytoreductive s...

Background: Autoimmune Addison disease (AAD) is a rare but highly heritable endocrinopathy. The BACH2 protein plays a crucial role in T lymphocyte maturation, and in particular in regulatory T cell formation, and allelic variation in its gene has been associated with autoimmune conditions such as type 1 diabetes, autoimmune thyroid disease and vitiligo. Its role in susceptibility to autoimmune Addison’s disease (AAD) has not been investigated.Aim: T...

Background: The autoimmune thyroid diseases, primary autoimmune hypothyroidism (AH) and Graves’ hyperthyroidism (GD), represent the most prevalent endocrine disorders. Although clinically distinct, they share several genetic susceptibility loci, many of which remain unidentified.TIGIT (T cell immunoreceptor with immunoglobulin and ITIM domains), expressed on the surface of T-cells, interacts with CD-155 on dendritic cells to form an alternative cost...

ACTH is a 39 amino acids polypeptide which stimulates adrenocortical steroid production. The N-terminal segment of ACTH(1–24) is biologically active and the C-terminal is considered to have greater antigenicity. In one previous (‘RoSA’) and one current (‘RADS2’) clinical trial synthetic ACTH (zinc tetracosactide; depot synacthen) was administered to autoimmune Addison’s disease (AAD) patients to stimulate adrenocortical regeneration. 4/13 RoSA pat...
