Abstract

OBJECTIVE: To assess the relationship between the first-trimester screening markers [pregnancy-associated plasma protein A (PAPP-A), free human chorionic gonadotrophin-β (fβ-hCG), nuchal translucency (NT)] and fetal birth weight and length in uncomplicated pregnancies. Design: Data about first-trimester screening markers and fetal birth weight and length were obtained from patient files and assessed. Setting: Gaziosmanpaşa University Faculty of Medicine Hospital, Department of Obstetrics and Gynecology, Tokat Patients: 97 patients who had an uncomplicated pregnancy course and were screened and gave birth in the hospital Interventions: First trimester aneuploidy screening and birth Main Outcome Measures: Any possible relation between fβ-hCG, PAPP-A, NT and birh weight and length that were standardized according to Turkish populationRESULTS: PAPP-A was positively correleted with the birth weight that was standardized according to Turkish population (r=0.236, p=0.02). PAPP-A was significantly lower in small for gestational age (SGA) babies when compared with normal weighing babies (p=0.042, 95% CI: 0.01-0.547). A PAPP-A cut-off value of ≤0.85 was foud to have a sensitivity of 100% for detection of SGA babies;however, its specificity was low. No correlation was found between any of the investigated parameters and the fetal length that was standardize according to Turkish population (for Z-fetal length and sβ-hCG, PAPP-A and NT MoM Pearson correlation coefficients were 0.049, 0.058 and 0.121 and p values were 0.632, 0.575 ve 0.242 respectively). CONCLUSION: Pregnancies that PAPP-A levels are found to be low during first trimester screening must be closely followed-up even no complication has been developed for risk of SGA babies.

Özet

Objektif: Komplikasyonsuz gebeliklerde serbest beta-human koryonik gonadotropin (sβ-hCG) ve pregnancy associated plasma protein-A’nın (PAPP-A) nukal şeffaflık (NT) ile birlikte bebek kilosu ve boyu ile olası ilişkisini araştırmak. Planlama: Birinci trimester anöploidi taraması esnasında ölçülen NT, maternal sβ-hCG ve PAPP-A, bebek doğum kilosu ve boyu ile ilgili veriler dosyalardan bulundu ve karşılaştırıldı. Ortam: Gaziosmanpaşa Üniversitesi Tıp Fakültesi Kadın Hastalıkları ve Doğum Anabilim Dalı, Tokat Hastalar: Birici trimester anöploidi taraması ve doğumu klinikte yapılan, gebeliğinde komplikasyon görülmeyen 97 gebe Girişim: Anöloidi taraması ve doğum Değerlendirme parametreleri: sβ-hCG, PAPP-A ve NT’nin ülkemize göre standardize edilmiş bebek kilosu ve boyu ile ilişkisi SONUÇ: PAPP-A’nın ülkemize göre standardize edilmiş bebek doğum kilosu ile pozitif bir korelasyon gösterdiği bulunmuştur (r=0.236, p=0.02). Gestasyonel yaşa göre küçük (SGA) bebeklerde PAPP-A değeri normal kilolu bebeklere oranla anlamlı olarak düşük tespit edilmiş (p=0.042, %95 Güven Aralığı: 0.01-0.547), ≤0.85 MoM’luk bir PAPP-A değerinin SGA ile doğacak bebekleri tespit etmede %100’lük duyarlılığa fakat düşük özgüllüğe sahip olduğu bulunmuştur. İncelenen parametrelerin hiçbirinin ülkemize göre standardize edilmiş bebek doğum boyu ile ilişkisinin olmadığı görülmüştür (Z-fetal boy ile sırasıyla sβ-hCG, PAPP-A ve NT MoM için Pearson korelasyon katsayıları 0.049, 0.058 ve 0.121 ve p değerleri 0.632, 0.575 ve 0.242). YORUM: Birinci trimester tarama testi esnasında PAPP-A seviyesi düşük bulunan gebeler, gebelikleri boyunca herhangi bir komplikasyon gelişmemesi durumunda bile bebek gelişimi açısından dikkatli takip edilmelidirler.
