About this study
Official title: Selenium Supplementation Treatment in Euthyroid Pregnant Women With Autoimmune Thyroid Disease: Effects on Obstetrical Complications
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.
Read the detailed description
Adverse outcomes, postpartum thyroid dysfunction and permanent hypothyroidism have been associated with isolated TPOab positivity in euthyroid pregnant women.
In areas with severe selenium deficiency there is a higher incidence of thyroiditis due to a decreased activity of selenium-dependent glutathione peroxidase activity within thyroid cells. Selenium-dependent enzymes also have several modifying effects on the immune system. Therefore, even mild selenium deficiency may contribute to the development and maintenance of autoimmune thyroid diseases.
Selenium substitution exerts anti-inflammatory and anti-oxidant activities. Se could represents an important supplementation in euthyroid women with AIT in order to improve thyroid function and structure and to prevent obstetrical adverse events related to autoimmune diseases and reactive oxygen species, such as recurrent miscarriage and pre-eclampsia.
The aim of this study is to document the effects of Selenium Supplementation with and without L-thyroxine (LT4) in euthyroid women with AIT, during pregnancy.
This protocol will evaluate the trend of TPOab and Tgab, selenium concentration, thyroid volume and echogenicity, nodule formation and number of adverse effects that affect the mother (during and after pregnancy), the fetus, the infant and the heath service, needing to elucidate the nature of the emerging associations.
The study also aims to assess the impact of Selenium Supplementation on implantation rate and pregnancy rate in women with transfer planned within the next 60 days.
This is designed as a phase IV study on treatment with a cohort size of pregnant women and women in whom embryo transfer is expected within 60 days with TSH value into the normal range (0.4-2.5 mUI/mL) and Tgab and/or TPOab positivity. We have performed two randomizations arms: Randomization arm A will include women LT4 replacement-free that will take Selenium or Placebo and Randomization arm B will include women already under LT4 replacement that will take Selenium or Placebo. Patients included in Randomization A will move into Randomization B, if TSH increases above 2.5 mUI/mL during pregnancy.
Pregnant women with TSH > 2.5 mU/mL at time 0 will begin (or will adjust) LT4 replacement and will be included in Randomization arm B.
Accounting for a 30% drop off, a total enrolment of 150 patients is planned. Patients will be randomized at time 0 (10°± 2 weeks of gestation). Follow-up visits will take place at weeks 14 ± 2, 24 ± 2, 32 ± 2, 36 ± 2 weeks, and between months 3° and 6° after labour. An optional visit could be done 12 months after labor. Plasma and serum monitoring of thyroid hormones, Tgab, TPOab, Se concentration, Selenoproteins and cytokines, thyroid US, SF12 questionnaire will be made at all the follow-up visits. At visit 3 (24 ± 2 weeks) patients will optionally do the OGTT). Gestational, obstetrical, maternal, fetal, and infant anamnestic data will be taken, during the follow up visits and at labour.
The long-term objective is to identify a safe and easily administered supplementation that improves:
- implantation and pregnancy rates in infertile women Tgab and/or TPOab positives
- maternal and fetal complication in pregnant euthyroid women Tgab and/or TPOab positives.

Questions about this trial
What is this clinical trial studying?
A study testing Selenium and Selenium + L-Thyroxine (LT4) in people with Pregnancy and Infertility, run by University of Roma La Sapienza at 11 sites in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 30 Jan 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 11 sites in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Changes in TPOab and/or Tgab (time frame: 0 and 14 ± 2, 24 ± 2, 32± 2, 36± 2 weeks; and between 3° and 6° month after labour; and optionally 12° after labour). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jan 2018.
