Active clinical trials for "Hashimoto Disease"

The aim of this study is to compare the thyroid hormone values and anti-thyroid peroxidase (anti-TPO) levels of women with a diagnosis of recurrent pregnancy loss (RPL) and healthy pregnancies. The primary objective is to find out the relationship between recurrent pregnancy loss with thyroid hormone levels and anti-TPO positivity.

Most of patients with autoimmune encephalitis are left with permanent cognitive deficits of varying severity. The patients' life and career would be affected definitely by cognitive deficits. Recently, more and more clinical physician have begun to focus on cognitive impairment of patients with autoimmune encephalitis. Generally, the outcome was measured by the modified Rankin Scale (mRS). However, the mRS are commonly used to evaluate the degree of disability or dependence in the daily activities of the patients suffering from a stroke and cognition function were minimally evaluated in this scale. It is crucial to adopt detailed cognition tools to study the long-term cognitive outcomes and as an indicator of overall curative effect judgment in autoimmune encephalitis. Currently, only early immunotherapy is uniformly and consistently considered to produce favorable cognitive outcomes. However, studies concerning the association of second-line immunotherapy with cognitive outcomes have been scarce and have shown conflicting results regarding autoimmune encephalitis. Hence, the goal of this study was to explore cognitive neural mechanism of autoimmune encephalitis by using neuropsychological tests and multi-mode MRIs.

Oxidative stress leads to or accompanies with numerous disease. Oxidative balance in subclinical hypothyroid or euthyroid state in Hashimoto disease are not known. Effect of levothyroxine therapy on oxidative balance are also not known in hashimoto disease.

The aim of the study is to assess the relationship between the concentration of bisphenol A in serum and selected parameters of thyroid function in women of reproductive age with thyroid dysfunction - Hashimoto's disease and Graves' disease.

The objective of this study is to evaluate the effect of vitamin D supplementation on thyroid autoimmunity, thyroid function, and other metabolic and clinical variables associated with the thyroid axis in patients with Hashimoto's thyroiditis and vitamin D deficiency.

This case control study aims to determine whether spontaneous coronary artery dissection (SCAD) is associated with autoimmune diseases and to update the incidence of SCAD in a population-based cohort.

Autoimmune encephalitis and paraneoplastic neurological syndromes are rare diseases caused by an abnormal immune response toward the nervous system. This can lead to life-threatening symptoms, but is in many cases treatable if a swift and correct diagnosis is made. Antibodies targeting neuronal proteins (i.e. "neuronal antibodies") can be detected in serum or cerebrospinal fluid (CSF) in about half of the patients suffering from these conditions. Although an important part of the diagnostical process of these conditions, diagnosis cannot be made only based on a positive antibody test, but the clinical findings have to be compatible as well. As these conditions are so rare, clinicians might struggle to interpret antibody test results. In this study the investigators aim to estimate the incidence rate of autoimmune encephalitides and paraneoplastic neurological syndromes in the Uppsala-Örebro health care region in Sweden between the years 2015 and 2019. Medical records from patients belonging to the Uppsala-Örebro health care region (a region in the middle of Sweden with a population of approximately 2.1 million), that tested positive for any neuronal antibody in serum or CSF will be studied to obtain clinical, laboratory and radiological data. This data will be used to ascertain if diagnostic criteria are fulfilled as well as to describe clinical characteristics and identifying possible comorbidities.

This study series consists of four related studies and aims to explore and describe many important elements of alopecia areata over three key areas: (1) the current epidemiology of alopecia areata, (2) the prevalence and incidence of psychiatric co-morbidities in people with alopecia areata, (3) the prevalence and incidence of autoimmune and atopic conditions in people with alopecia areata, and (4) the incidence of common infections in people with alopecia areata.

Autoimmune diseases represent a heterogeneous group of pathologies whose etiopathogenic mechanisms are most often unknown. Autoimmune diseases are the leading cause of morbidity and mortality in young women and autoimmune thyroid diseases are the most common. Viral infections are the main environmental factors suspected of triggering autoimmune diseases. Several viruses are certainly involved, all of which are possibly capable of triggering an autoimmune response. However, the precise identification of the viruses involved remains to be established. It has been shown for the first time by the 2005 PHRC that enteroviral RNA is present in perioperative specimens of thyroid tissue. However, this case-control study did not show any difference between the thyroid group and the group other thyroid pathologies It has been recently published that Parvovirus is possibly involved in thyroiditis: the parvoviral genome is present in the thyroid tissue of Hashimoto thyroiditis operated and more precisely is present within the thyrocytes itself.

This will be a population based study looking at the prevalence of thyroid disorders in Malaysia (including hypo- and hyperthyroidism, subclinical hypo- or hyperthyroidism) and its association with different ethnicity and iodine status. The study will also look at genetic susceptibility for autoimmune thyroid disorders in the Malaysian population General hypotheses: The prevalence of thyroid disorders in Malaysia is 10% for hypothyroidism and 2% for hyperthyroidism Hypo- and hyperthyroidism is associated with iodine status in our population There are different susceptibility gene for autoimmune thyroid disorder in different ethnicity in our population
