title: [Thyroid function in pregnant women with pregnancy induced hypertension].
abstract: OBJECTIVE
  The aim of this study is to investigate thyroid's function in pregnant women with pregnancy induced hypertension.
  
  
  METHODS
  42 pregnant women with PIH diagnosed after 20 weeks of gestation (between 22-30 hbd) were hospitalized in Department of Obstetrics and Gynecology of Mother and Child Institute in Warsaw. This group consisted 20 multiparous and 22 primiparous. We measured thyroid hormone levels: TSH, fT4, fT3 and TBG.
  
  
  RESULTS
  In 8 pregnant women (5 primiparous and 3 multiparous) thyroid function was normal (normal level of TSH, fT3, fT4) and middle blood pressure in term of beginning of the study was 155/100 mmHg. 34 pregnant women (19 primiparous and 15 multiparous) had abnormal thyroid function. 3 (1 primiparous and 2 multiparous) pregnant women of this group had subclinical hyperthyroidism (middle blood pressure in the beginning of the study was 155/105) and 31 (21 primiparous and 10 multiparous) had fT4 and fT3 levels lower then normal range with normal TBG levels. In this group only one patient TSH level was higher then 5 mlU/l, which allows to recognize overt hypothyroidism. In other cases the results indicate the subclinical hypothyroidism. The middle blood pressure was 140/95 mmHg.
  
  
  CONCLUSIONS
  1. Thyroid dysfunction in pregnant women was concluded in 78.2% of tested group. 2. Subclinical hypothyroidism was concluded the most frequent in the tested group. 3. The middle blood pressure at the term of beginning of the study was the lowest in pregnant women with hypothyroidism. 4. The thyroid function tests should be performed in all pregnant women with PIH.
