Iron Deficiency Anemia and Iodine Prophylaxis in Pregnant Women

Abstract

The aim of this study was estimate the influence of Iron Deficiency Anemia (IDA) on efficiency of the iodine prophylaxis for pregnant women, and also to offer the optimal levels of daily iodine intake during pregnancy and lactation. Materials and methods: serum thyroid stimulating hormone (TSH), free thyroxin (fT4), AT-TPO concentrations, urine excretion of iodine, levels of hemoglobin (Hb), hematocrit (Ht), red blood cell (RBC), mean corpuscular hemoglobin (MCH), serum iron levels and serum ferritin were measured. The volume of thyroid gland was defined by ultrasonography. The pregnant women were divided into two groups: Group 1 (n = 111) – KI (200 micro# grams/day) and Group 2 (n = 109) – KI (300 micrograms/day). Results: Median urinary iodine was 140,8 μg/l. During pregnancy there was an authentic rising of a median urinary iodine to 259,6 μg/l in group 2 (p = 0,0000) and in group 1 the iodine excretion in urine was more low than at a stage of screening and has compounded 96,9 μg/l (p = 0,002). During lactation there was an insufficient concentration of iodide in urine in group 1 and in group 2 there were normal indexes of a median urinary iodine – 88,6 and 123,2μg/l in groups 1st and 2nd accordingly (p = 0,004). In the third trimester 21,5% of women had a latent deficiency of iron. Authentic correlation between indexes of an iron deficiency anemia and iodine deficiency has not been detected. Conclusion: The median level of urinary iodine indicate optimal iodine nutrition during pregnancy and lactation and the requirement of iodine is at least 300 μg/day. In our research the negative influence of iron deficiency anemia on the efficiency of iodine prophylaxis during pregnancy has not been detected.
