ABSTRACT

Introduction: Hyperthyroidism is the second most frequent endocrine disease after diabetes mellitus that presents itself during pregnancy. It occurs in two out of every 1,000 pregnancies. The newborns may be hypo, hyper or euthyroid. Objective: To determine the morbility of the infants born to mother’s with hyperthyroidism and the mother’s general condition. Material and methods: With a simple cohort, we accomplished an observational, retrospective study, in a institutional facility, where we studied both maternal and neonatal variables. We used central tendency and frequency measurements. Results: In our study we included 141 hyperthyroid mothers, with an incidence of 0.5%, from which 90.8% corresponded to Graves Disease. 71.8% were treated with methamizol. The mayority of the deliveries were by cesarean. The average gestational age was: 37.6 ± 2.2 weeks, weight: 2794 ± 636 grams. We did neonatal screening on 126 patients and thyroid fuction tests on 48. 7 patients were positive for congenital hyperthyroidism (5%), and 2 for hypothyroidism (1.4%). 13 (9.2%) newborns presented some clinical data which was attributed to a thyroid disorder. Conclusions: The incidence of hyperthyroid mothers was of 0.48%. Graves Disease being the etiology in 90.8% of the cases. Congenital hyperthyroidism was found in 5%, the predominant symptoms were tachycardia and irritability.
