Screening for Maternal Thyroid Dysfunction in Pregnancy : A Review of the Clinical Evidence and Current Guidelines

الملخص EN

Observational studies have demonstrated that maternal thyroid dysfunction and thyroid autoimmunity in pregnancy may be associated with adverse obstetric and fetal outcomes.

Treatment of overt maternal hyperthyroidism and overt hypothyroidism clearly improves outcomes.

To date there is limited evidence that levothyroxine treatment of pregnant women with subclinical hypothyroidism, isolated hypothyroxinemia, or thyroid autoimmunity is beneficial.

Therefore, there is ongoing debate regarding the need for universal screening for thyroid dysfunction during pregnancy.

Current guidelines differ; some recommend an aggressive case-finding approach, whereas others advocate testing only symptomatic women or those with a personal history of thyroid disease or other associated medical conditions.
