Abstract

Amaç: Konjenital hipotiroidizm (KH) dünya çapında zihinsel engelliğin önlenebilir ve önde gelen nedenidir. Konjenital
hipotiroidi prevalansı yaklaşık 1/3000’dir. Hipotiroidi, özellikle hasta olanlarda olmak üzere prematürelerde term bebeklere
göre daha sıktır. Çalışmamızda çok düşük doğum ağırlıklı (ÇDDA; <1500g) olan hastalarda KH sıklığını saptamayı
amaçladık.
Gereç ve Yöntemler: Çalışma 52 aylık dönem boyunca yatan ÇDDA bebeklerin tıbbi kayıtlarının retrospektif olarak
değerlendirilmesi neticesinde gerçekleştirildi. İlk yatıştan sonra 5 günden uzun yaşayan hastaların tiroid fonksiyon testleri
(TFT), [serbest tiroksin (sT4), tiroid stimülan hormon (TSH)] kayıt edildi. Anormal sonucu olan hastaların kontrol TFT sonuçlarına
göre hastalar alt gruplara ayrıldı. KH grubuna tiroid hormon takviyesi yapıldı.
Bulgular: Çalışmaya 5. günde alınan TFT sonucu elde edilebilen 581 hasta dahil edildi. Yetmişdokuz hastadan alınan
ilk TFT anormal, ikinci kontrolde 26 hastanın TFT değerleri anormal olması nedeniyle KH tanısı konularak tiroid hormon
takviyesi verildi. Çok düşük doğum ağırlıklı yenidoğanlarda KH oranı %4.4 (1/23) olarak tespit edildi. Ayrıca KH olan
hastaların gebelik haftaları, doğum ağırlığı anlamlı olarak daha düşük (sırasıyla p<0,00, p=0,037), kız cinsiyet oranı daha
yüksek (p=0.017) bulunmuştur.
Sonuç: Konjenital hipotiroidi oranı ÇDDA prematürelerde daha düşük gebelik haftası ve doğum ağırlığı ile kız cinsiyette
yüksek bulunmuştur. Prematürelerde tiroid fonksiyon bozukluğu yaygın olarak izlenmektedir. Özellikle prematürelerde
nörogelişimsel sonuçlar düşünüldüğünde tiroid fonksiyon testlerinin tekrarı KH’yi tespit etme açısından önemlidir.

The publication language of Turkish Journal of Pediatric Disease is English.


Manuscripts submitted to the Turkish Journal of Pediatric Disease will go through a double-blind peer-review process. Each submission will be reviewed by at least two external, independent peer reviewers who are experts in the field, in order to ensure an unbiased evaluation process. The editorial board will invite an external and independent editor to manage the evaluation processes of manuscripts submitted by editors or by the editorial board members of the journal. The Editor in Chief is the final authority in the decision-making process for all submissions. Articles accepted for publication in the Turkish Journal of Pediatrics are put in the order of publication, with at least 6 original articles in each issue, taking into account the acceptance dates. If the articles sent to the reviewers for evaluation are assessed as a senior for publication by the reviewers, the section editor and the editor considering all aspects (originality, high scientific quality and citation potential), it receives publication priority in addition to the articles assigned for the next issue.


The aim of the Turkish Journal of Pediatrics is to publish high-quality original research articles that will contribute to the international literature in the field of general pediatric health and diseases and its sub-branches. It also publishes editorial opinions, letters to the editor, reviews, case reports, book reviews, comments on previously published articles, meeting and conference proceedings, announcements, and biography. In addition to the field of child health and diseases, the journal also includes articles prepared in fields such as surgery, dentistry, public health, nutrition and dietetics, social services, human genetics, basic sciences, psychology, psychiatry, educational sciences, sociology and nursing, provided that they are related to this field. can be published.
