Whereas in regions with sufficient iodide intake treatment of thyroid nodules with levothyroxine has been almost completely abandoned and is also not further recommended by guidelines, medical treatment may be still indicated in Germany as recently demonstrated by randomized, placebo-controlled LISA study.A major reason for this is mild iodide deficiency in patients with thyroid nodules. In LISA study a combined therapy of levothyroxine and iodide resulted in an at least 50 % reduction of nodular volume in 21,6 % of treated patient compared to in only 5,2 % of placebo-treated patients...

Immune check point inhibitors have revolutionized the treatment of metastatic malignancies. They are a promising area in oncology and more drugs are likely to be available in the coming years. Along with the promise of better response oncologically, there is an increased incidence of endocrinopathies related to autoimmunity. This case report illustrates the dramatic development of hypothyroidism in a patient with underlying subclinical hyperthyroidism. It also suggests the potential pretreatment predictors of endocrinopathies related to these immune check point inhibitors...

INTRODUCTION: Secondary and tertiary preventions are concerned with the recognition of the disease process in a very early stage and delay in progression to complete disease and minimization of complications and the impact of illness. METHODS: All articles related to secondary and tertiary prevention of thyroid diseases were reviewed. Using related key words, articles published between 2001 and 2015 were evaluated, categorized, and analyzed. RESULTS: In secondary prevention, congenital hypothyroidism and subclinical hypo and hyperthyroidism are equally important...

BACKGROUND: Graves' is disease an autoimmune disorder of the thyroid gland caused by circulating anti-thyroid receptor antibodies (TRAb) in the serum. TRAb mimics the action of thyroid stimulating hormone (TSH) and stimulates the thyroid hormone receptor (TSHR), which results in hyperthyroidism (overactive thyroid gland) and goiter. Methimazole (MMI) is used for hyperthyroidism treatment for patients with Graves' disease. METHODS: We have developed a model using a system of ordinary differential equations for hyperthyroidism treatment with MMI...

Background/aim: Hyperthyroidism causes hemodynamic changes that are associated with adverse cardiovascular outcomes. Twenty-four-hour ambulatory blood pressure monitoring recordings provide us with some essential data: BP variability and ambulatory arterial stiffness index (AASI). In this study, we aimed to investigate AASI and short-term BP variability in both overt and subclinical hyperthyroidism and their relationship with thyroid hormones. Materials and methods: We enrolled 36 patients with subclinical hyperthyroidism, 23 patients with overt hyperthyroidism, and 25 healthy euthyroid controls...

Type 2 diabetes mellitus (T2DM) and thyroid disorders (TD) are the two most common endocrine disorders in clinical practice. Unrecognized thyroid disorders may adversely affect the metabolic control and add more risk to an already predisposing type 2 diabetes mellitus. The objective of the study is to find out the percentage of hypothyroidism and hyperthyroidism in patients with type 2 diabetes mellitus and non diabetic subjects. This cross-sectional study was conducted in the department of Biochemistry and outpatient Department of Endocrinology, BIRDEM General Hospital, Dhaka, Bangladesh from July 2014 to June 2015...

Graves' disease is the most frequent cause of hyperthyroidism in iodine-sufficient geographical areas and is characterized by the presence in patients' serum of autoantibodies directed against the thyrotropin receptor (TRAb) that cause overproduction and release of thyroid hormones. Clinical presentation results from both hyperthyroidism and underlying autoimmunity. The diagnosis is based on characteristic clinical features and biochemical abnormalities. If serum thyrotropin (TSH) is low, serum free thyroxine (FT4) and free triiodothyronine (FT3) concentrations should be measured to distinguish between subclinical (with normal circulating thyroid hormones) and overt hyperthyroidism (with increased circulating thyroid hormones)...

BACKGROUND: Lately, high dose of biotin is often given orally to patients with a primary progressive multiple sclerosis (PPMS). However, the molecule biotin is also a principle compound in various analytic immunoassays. CLINICAL CASE: An asymptomatic 60-year-old woman with PPMS on high dose of biotin therapy (3 × 100 mg/d) displayed abnormal thyroid function tests (TSH 0.02 mU/l, fT4 > 103 pmol/l, and fT3 > 46 pmol/l). TSH was determined by a homogeneous sandwich chemiluminescent immunoassay and fT4 and fT3 were both determined by a homogeneous, sequential, chemiluminescent immunoassay...

BACKGROUND AND AIMS: The role of subtle thyroid alterations, such as subclinical thyroid disease and low/high serum thyrotropin (TSH) within the normal range, on cognitive decline is controversial. The aim of this study was to evaluate the association of serum TSH and subclinical thyroid dysfunction with performance on cognitive tests in a large sample of Brazilian middle-aged adults without overt thyroid disease. METHODS: In this cross-sectional analysis of the Brazilian Longitudinal Study of Adult Health, we excluded individuals aged 65 years and older, with overt thyroid dysfunction, prevalent stroke, in use of medications that affect thyroid function or that indicate neurologic diseases, and from Asian or indigenous ethnicity...

Although 85% of patients with univentricular heart after Fontan procedure survive twenty years after operation, the procedure alone seems to be an inadequate treatment as a permanent clinical solution. Patients with a "Fontan physiology" additionally have to face a various extra-cardiac complications, including thyroid, liver and kidney dysfunction, which are not only potentially life-threatening, but also can potentiate the circulatory insufficiency. AIM: The aim of the study was to assess a multiorgan dysfunction in adult patients after Fontan operation in long term follow-up and compare to healthy controls...

Polyglandular autoimmune syndromes (PAS) is a group of heterogenous conditions characterized by the association of at least two organ-specific autoimmune disorders, concerning both endocrine and non-endocrine organs. Type III is defined as the combination of autoimmune thyroid disease and other autoimmune condition (other than Addison's disease) and is divided into four subtypes. We describe a teenage female patient - with the family history of autoimmune diseases, who has simultaneously developed the symptoms of autoimmune thyroid disease with the clinical picture of hyperthyroidism and myasthenia gravis at the age of fifteen...

BACKGROUND: Measurement of serum IgG4 had been suggested to distinguish the unique subtypes of autoimmune thyroid disease (AITD) which demonstrated patterns of fluctuating between hyperthyroidism and hypothyroidism. However, the clinical utility of serum IgG4 measurement is inconclusive due to few studies having addressed these unusual patients compared with the specificity of serum IgG4 in healthy patients. AIM: To investigate whether elevated serum IgG4 levels could be used as a marker to identify fluctuating AITD patients...

Thyroid dysfunction is the commonest endocrine disorder in pregnancy apart from diabetes. Thyroid hormones are essential for fetal brain development in the embryonic phase. Maternal thyroid dysfunction during pregnancy may have significant adverse maternal and fetal outcomes such as preterm delivery, preeclampsia, miscarriage and low birth weight. In this review we discuss the effect of thyroid disease on pregnancy and the current evidence on the management of different thyroid conditions in pregnancy and postpartum to improve fetal and neonatal outcomes, with special reference to existing guidelines on the topic which we dissect, critique and compare with each other...

Depression has repeatedly been linked to subclinical hypothyroidism, and thyroid hormones have successfully been used to augment antidepressant treatment. By contrast, the extent of thyroid dysfunction in anxiety disorders remains less clear. This is surprising, given that anxiety-related symptoms (e.g., nervousness, palpitations, increased perspiration) are highly prevalent in hyperthyroidism. The present study was undertaken to synthesize the literature on hypothalamic-pituitary-thyroid (HPT) axis functioning in anxiety disorders...

BACKGROUND: Atrial fibrillation (AF) is a highly prevalent disorder leading to heart failure, stroke, and death. Enhanced understanding of modifiable risk factors may yield opportunities for prevention. The risk of AF is increased in subclinical hyperthyroidism, but it is uncertain whether variations in thyroid function within the normal range or subclinical hypothyroidism are also associated with AF. METHODS: We conducted a systematic review and obtained individual participant data from prospective cohort studies that measured thyroid function at baseline and assessed incident AF...
