Abstract

Hyperthyroidism is one of the main endocrinopathies during pregnancy. The aim of this project was to identify the degree of control of hyperthyroid pregnant women based on the recommendations of the American Thyroid Association (ATA) in a real situation without the availability of propylthiouracil. This was a descriptive, retrospective and longitudinal study, including medical files of pregnant women with hyperthyroidism between 18 and 35 years. They were classified as having "Adequate" control if their thyroid profiles were within the recommendations of the ATA and had no adrenergic symptoms; and were categorized as having "Inadequate" control if they were not stabilized with monotherapy, or if they required high doses of antithyroid drugs or beta-blockers or showed serious complications including the need of an Intensive Care Unit (ICU) for mothers or neonates. The Chi square test was performed between treatment groups during the third trimester and the complications of pregnant women or neonates. A total of 173 hyperthyroid pregnant women were studied with an average age of 21 ± 4.7 years. Of the 33 patients with hyperthyroidism who received monotherapy with methimazole until the end of pregnancy, 23 (69.69%) were classified as having "Adequate" control. In a real life situation there is delay in the diagnosis of hyperthyroidism during pregnancy but even without propylthiuracil, an “Adequate” control can be reached in up to 20.53% of cases based on a methimazole monotherapy.
