Hashimoto Disease, Pregnancy Related, Thyroid Dysfunction
Conditions
Brief summary
The management of thyroid function in pregnancy has been object of several guidelines in the last years. Normal thyroid function reduces prenatal and post-natal risks and gestational complaints. Trimester specific reference values of thyroid hormones and thyroid stimulating hormone (TSH) are available for selected geographic population but its are not yet are available in our country. Hashimoto's thyroiditis (HT) is the most frequent autoimmune thyroid disease which can induce thyroid dysfunction, mainly sub-clinical hypothyroidism. Due to the large incidence in women HT and its potential link with thyroid dysfunction this disease could be search and monitored before pregnancy. Anyway a strong recommendation is to test TSH levels in all patients seeking pregnancy at risk for thyroid dysfunction for a history or current symptoms/signs of thyroid dysfunction, known positivity od thyroid autoimmunity or goiter, a history of neck radiation, age \>30 years, diabetes mellitus, previous infertility or pregnant loss, morbid obesity, living in area of moderate-severe iodine deficiency or recent administration of drugs/substance interfering with thyroid function.
Detailed description
The aim of the study was to retrospectively evaluate from 2011 (data of publication of the first American Thyroid Association (ATA) guidelines for thyroid dysfunction in pregnancy) to now medical record of the a secondary level endocrine unit to verify the adherence to guidelines in the management of thyroid function in pregnant women with HT. The investigators search 1. the adherence to clinical and biochemical endocrine evaluations before conception 2. the use (correct/un-correct) of L-T4 intervention and its monitoring 3. the difference in thyroid function control between women with a fix increment of- L-T4 posology (25 mcg/week more for each 2 kg increment in body weight) after the initial L-T4 adjustment or prescription 4. the clinical and biochemical endocrine evaluation 1-2 months after delivery 5. the outcome of pregnancy 6. the e-mail up-to-date survey on current of off-springs health
