Abstract

Objective: Recent studies have demonstrated an increase inthe prevalence of hypothyroidism among pregnant women. Since hypothyroidism during pregnancy may increase fetoma-ternal morbidity, it is imperative to study the reason underlying this condition. Therefore, the present study was aimed to as-sess the iodine status in pregnant women and its correlation with hypothyroidism. Material and Methods: The presentstudy was designed as a cross-sectional study to detect thyroid dysfunction in pregnant women in a tertiary-care hospital set-ting. Detailed demographics and the medical and obstetric his-tory of the included subjects were recorded, and their baseline serum thyrotropin (TSH) and urinary iodine levels were deter-mined. The women diagnosed with hypothyroidism were sub-jected to reflex testing for thyroid peroxidase antibodies (TPOAb). Results: The Median Urinary Iodine concentration ofthe study population, determined using the spot urinary iodine concentration of 545 women, was 255μg/L, which was higher than the level recommended in the WHO Guidelines. Among the 33% women (n=180) detected to be hypothyroid (TSH level >2.5mIU/L in the 1st trimester or >3.0mIU/L in the 2nd or 3rd trimester), 32% women (n=67) were positive for TPOAb. The correlation between the TSH levels and the urinary iodine levels was not significant (p=0.688); a significant correlation was ob-served between the urinary iodine levels and positivity for TPOAb (p=0.047). Conclusion: The current iodine statusamong pregnant North Indian women indicates a trend toward Iodine excess, with a significant association with the high pre-valence of thyroid autoimmunity in the study population.

Özet

Amaç: Son çalışmalar, gebelerdeki hipotiroidizm prevalansındabir artış olduğunu göstermiştir. Gebelikte hipotiroidizm fetoma- ternal morbiditeyi artırabileceğinden, bu durumun altında yatannedeni araştırmak şarttır. Bu nedenle, bu çalışmada gebelerdeiyot durumu ve hipotiroidizm ile ilişkisinin değerlendirilmesiamaçlanmıştır. Gereç ve Yöntemler: Bu çalışma, 3. basamakhastane ortamında gebelerdeki tiroid disfonksiyonunu sapta- maya yönelik kesitsel bir çalışma olarak tasarlanmıştır. Çalış- maya alınanların ayrıntılı demografik özellikleri ve tıbbi veobstetrik geçmişleri kaydedilmiş ve başlangıç serum tirotropin(TSH) seviyeleri ve idrar iyot seviyeleri belirlenmiştir. Hipotiroi- dizm teşhisi konan kadınlara, tiroid peroksidaz antikorları(TPOAb) için refleks testi uygulanmıştır. Bulgular: Çalışma po- pülasyonundaki 545 kadının, spot idrar iyot konsantrasyonu kul- lanılarak, belirlenen Medyan İdrar İyot konsantrasyonu 255μg/Lidi ve bu Dünya Sağlık Örgütü Kılavuzları’nda önerilen seviyedendaha yüksekti. Hipotiroid (TSH seviyesi 1. trimesterde >2,5 mIU/L ya da 2. veya 3. trimesterde >3,0 mIU/L) olduğu tespitedilen 180 kadından (%33) 67’sinde (%32) TPOAb pozitifti. TSHseviyeleri ile idrar iyot seviyeleri arasındaki korelasyon anlamlıdeğildi (p=0,688); TPOAb pozitifliği ile idrar iyot seviyeleri ara- sında ise anlamlı bir korelasyon gözlendi (p=0,047). Sonuç:Kuzey Hindistanlı gebe kadınlar arasındaki mevcut iyot durumu,çalışma popülasyonundaki yüksek tiroid otoimmünite prevalansıile anlamlı bir ilişki gösteren iyot fazlalığına doğru bir eğilim ol- duğunu göstermektedir.
