Anemia is a highly prevalent condition among pregnant women in the Republic of Kazakhstan. The causes of this anemia are not quite clear, as is the problem of resistance of this type of anemia to therapy with iron preparations. The authors propose that this may be explained by the fact that many regions of the Republic are foci of endemic goiter, because tentative studies indicate a relationship between endemic goiter and hypothyrosis. The present study was aimed at examination of the thyroid status in pregnant women suffering from anemia in the town of Alma-Ata, a region endemic for goiter. Altogether 120 anemic pregnant women were examined, 60 of these with goiter and 60 without it. Control group consisted of 20 healthy pregnant women. Clinical and ultrasonic examinations, puncture biopsy of the thyroid, measurements of blood levels of TTH, total and free triiodothyronine and thyroxin, thyroxin-binding globulin, as well as of peripheral blood red cell counts, levels of hemoglobin, serum iron, assessment of total iron-binding capacity of the serum and saturation coefficient, were carried out. Healthy pregnant women from a focus of endemic goiter were found to represent a group at risk of anemia in the third pregnancy trimester. In anemic pregnant women endemic goiter aggravated anemia. Chronic iodine deficiency is conductive to formation in pregnant women of subclinical hypothyrosis whose severity increased in the presence of anemia, more so if anemia is paralleled by goiter. |
