ABSTRACT
Background:
Untreated functional thyroid diseases are a risk factor for maternal and fetal complications during pregnancy.Aim:
To determine the frequency of functional or autoimmune thyroid disease in healthy women during the first trimester of pregnancy. Subjets andMethods:
healthy pregnant women attending a routine consult during their first trimester of pregnancy were studied. Thyroid stimulating hormone (TSH), total and free thyroxin (T4) anti-thyroid peroxidase (TPO) antibodies and spot urine iodine levels were measured. The reference ranges provided by the Atlanta Georgia Consensus in 2004 were used as normal values. A urine iodine concentration < 150 ug/L was considered low.Results:
One hundred women age 30 +/- 5 years with a mean gestational age of 8,8 +/- 1,9 weeks, were studied. The frequencies of subclinical hypothyroidism, clinical hypothyroidism, isolated low thyroxin lecels, high antiTPO antibodies and low urine iodine levels were 19, 2, 3, 13 and 15 percent, respectively. Women with high TSH levels had lower total and free T4 levels.Conclusions:
Twenty one percent of this sample of apparently healthy pregnant women had a clinical or subclinical hypothyroidism.Palavras-chave
