Auto-immune Thyroiditis clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Selenium Supplementation in Pregnancy

Serena

Start date: April 2012
Phase: N/A
Study type: Interventional

Serum levels of isolated anti-thyroperoxidase (TPOab) and anti-thyreoglobulin (Tgab) autoantibodies are strongly associated with an increased risk of miscarriage and premature deliveries in euthyroid pregnant women. Replacement of thyroxine (LT4) or other supplementations in euthyroid-Ab positivity during pregnancy has not been established. The development of a safe and effective intervention that modulates inappropriate inflammatory responses could be a very important component of prevention against adverse health outcomes during pregnancy. The anti-oxidant Selenium (Se) suppresses autoimmune destruction of thyrocytes and at daily dose of 200 mcg and 100 mcg decreases titers of serum TPOAb and TgAb also in Se-non-deficient patients with autoimmune thyroiditis (AIT). The use of Se in AIT has been shown to reduce the incidence of postpartum thyroiditis and hypothyroidism. Women with recurrent pregnancy loss had lower Se levels and Se deficiency has been implicated in the pathogenesis of AIT and in the impairment of T/B cell-mediated immunity. The purpose of the present study is performed to establish the effect of Se supplementation in euthyroid women with AIT (pregnant and in whom embryo transfer is expected within 60 days) on Ab trend, thyroid function and structure, implantation rates, pregnancy rates, pregnancy outcome and number of obstetrical, fetal and neonatal complications.
