METTL3 gene polymorphisms contribute to susceptibility to autoimmune thyroid disease

ConclusionOur study for the first time revealed a strong correlation betweenMETTL3 mutations and AITD predisposition, implying thatMETTL3 may be a new candidate gene for AITD treatment.

AbstractIn recent years, the frequency of infections due to saprophytic fungi has increased.Cryptococcus laurentii, recently classified asPapiliotrema laurentii, is responsible for fungemia, meningitis, and superficial infections. Here, we report the first case of cutaneousPapiliotrema (Cryptococcus)laurentii infection in a 23-year-old Caucasian woman affected by an autoimmune thyroiditis with hypothyroidism. Impairments of the immune system are often associated with unusual fungal infections, which cannot be neglected. The isolate strain was susceptible to Amphotericin B while resistant to fluconazole, itraconazole, voric...

Authors: Halczuk KM, Boguszewska K, Urbaniak SK, Szewczuk M, Karwowski BT Abstract The thyroid is not necessary to sustain life. However, thyroid hormones (TH) strongly affect the human body. Functioning of the thyroid gland affects the reproductive capabilities of women and men, as well as fertilization and maintaining a pregnancy. For the synthesis of TH, hydrogen peroxide (H2O2) is necessary. From the chemical point of view, TH is a reactive oxygen species (ROS) and serves as an oxidative stress (OS) promoter. H2O2 concentration in the thyroid gland is much higher than in other tissues. Therefore, the thyroid is...

CONCLUSIONS: Oxidant/antioxidant imbalance represent a key feature of thyroid autoimmunity. Oxidative stress parameters could be used as biochemical markers of chronic inflammation, to better predict the disease evolution along its natural history. Dietary habits and antioxidant supplements may provide protection from autoimmunity, opening new perspectives in the development of more tailored therapies.

AbstractHeterozygous gain-of-function (GOF) mutations inSTAT1 in patients with chronic mucocutaneous candidiasis (CMC) and hypothyroidism were discovered in 2011. CMC is the recurrent or persistent mucocutaneous infection byCandida fungi, and hypothyroidism results from autoimmune thyroiditis. Patients with these diseases develop other infectious diseases, including viral, bacterial, and fungal diseases, and other autoimmune manifestations, including enterocolitis, immune cytopenia, endocrinopathies, and systemic lupus erythematosus.STAT1-GOF mutations are highly penetrant with a median age at onset of 1  year and oft...

Autoimmune thyroid disease (ATD) is the most frequent cause of acquired thyroid dysfunction, most commonly presenting either as Hashimoto's thyroiditis or Graves' Disease. Hashimoto's thyroiditis is characterized by the presence of thyroid-specific autoantibodies, more commonly anti-thyroperoxidase antibodies in the serum and the typical inhomogeneous echostructure of the thyroid on a thyroid ultrasound examination. Hashimoto's thyroiditis can for a long time be accompanied by normal thyroid function and hypothyroidism can only progressively be established. Graves' disease is much less frequent in childhood and adolescence...

CONCLUSION: Metformin significantly reduces TPOAb level and TgAb level in patients with HT and SH, especially TPOAb. This study is the first to provide a preliminary theoretical basis for the clinical application of metformin in the treatment of HT. PMID: 32741222 [PubMed - as supplied by publisher]

Background: Immunological and hormonal disorders have undoubted influence on the development of atherosclerotic process. Autoimmune diseases accompanying type 1 diabetes (T1D) may additionally accelerate atherosclerosis progression and increase the risk of cardiovascular events in the future. The influence of subclinical hypothyroidism on the cardiovascular system, in particular, has recently aroused great interest. The aim of our study was to assess intima-media thickness (cIMT) of common carotid arteries and the occurrence of classical atherosclerosis risk factors together with selected new biomarkers of cardiovascular d...

Conclusion: In children with severe hypothyroidism, the most sensitive symptoms are growth arrest and weight gain despite the fact that, in some children, the auxological parameters at presentation could be within normal values for the population. The specific biochemical profile closely correlates to the severity of thyroid hormone deficiency and involves mostly erythropoiesis, liver function, and kidney function. Pituitary enlargement should be considered in each child with severe hypothyroidism. It is necessary to conduct prospective studies evaluating the actual frequency of anti-TSHR antibodies and pituitary enlargeme...

CONCLUSIONS: After exclusion of other causes, the unexplained reoccurring hypoglycemia can be a remarkable feature of autoimmune polyendocrine syndromes in immune-mediated type 1 diabetes mellitus on intensive insulin replacement therapy. PMID: 32597157 [PubMed - in process]
