A possible explanation could be disruption of embryonic blood vessels which become fragile due to mutation in a gene involved in vasculogenesis.7,8 Other hypotheses include rupture of amniotic bands,9 teratogenic factors, intrauterine infections like chickenpox, zoster or herpes simplex, fetal exposure to cocaine, heroin, alcohol or
antithyroid drugs, oligohydramnios and external compressions.10
Forty-one patients with recurrent Graves' disease who had been receiving
antithyroid medication (methimazole) for at least two years were randomly assigned to receive selenium (100 [micro]g twice a day as sodium selenite) or no selenium (controls) for six months.
We present a case of a patient with hypothyroidism with acute onset psychotic symptoms and positive
antithyroid antibodies without a previous psychiatric history.
While thyroid hormones produced by or given to the mother cross the placenta in only limited amounts, both thyroid antibodies and
antithyroid drugs (ATDs) readily cross the placenta and affect fetal thyroid function.
The performance indicators to study the effects of such interventions used the following ratios of the requests for related tests: AST to alanine transaminase (AST/ALT); AGA to antitissue transglutaminase antibodies (AGA/anti-tTG), TgAb to
antithyroid peroxidase antibodies (TgAb/TPOAb),TBIL/ALT, GGT/ALT, iron to ferritin, FT4 to thyroid-stimulating hormone (FT4/TSH), ESR to C-reactive protein (ESR/CRP), and urea to creatinine.
Management of thyroid storm and uncontrolled hyperthyroidism overall incorporates a similar approach, including treatment with beta-adrenergic blockers and
antithyroid hormones; however treatment of thyroid storm also includes adding inorganic iodine or corticosteroids and aggressively treating manifestations of the disease.
Adult patients with GD treated with
antithyroid drugs achieve long-lasting remission from 40 to 60% [9, 10].
So far, inconsistent data has been conveyed on the cardiovascular outcomes following euthyroidism restoration in hyperthyroid patients either by effective
antithyroid therapy [3,10,11] or by thyroidectomy [16,17].
Moreover, these findings suggest to us that we can apply
antithyroid agents, pan-heme peroxidase inhibitors, to drug repositioning for antiasthma drugs.
It is important to remember that the measurement of
antithyroid antibodies offers diagnostic information about the etiology of the disease but provides no insight into thyroid function.
Women with endometriosis, polycystic ovarian syndrome or premature ovarian failure have very often high levels of
antithyroid autoantibodies.
Hashimoto's thyroiditis diagnosis was determined by elevated levels of the antibodies
antithyroid peroxidase and/or antithyroglobulin, as well as ultrasound results.
