Determination of Vitamin D Metabolism and Bone Strength by Quantitative Ultrasound in Term Newborns

Öz:

INTRODUCTION: Insufficient intake of vitamin D negativelyeffects bone mineralization and turnover. Changes in mothers’bone turnover during pregnancy effects bone mineralcomposition of the fetus. The aim of this study was to evaluatethe factors, biochemical markers and bone structure assessedby quantitative ultrasonography effecting vitamin Dmetabolism.METHODS: Ninety term newborn and their mothers includedin the study. Serum levels of Ca, P, alkaline phosphatase(ALP), bone ALP (BALP), 1,25(OH)2D, 25(OH)D, parathyroidhormone (PTH), and osteocalcine levels were analyzed fromthe serums of mothers. Quantitative ultrasound from the tibialbone was performed for all infants during the first 96 hoursRESULTS: Mean values for 25(OH)D and 1,25(OH)2D werewithin normal ranges in mothers. Mean blood Ca levels of thenewborns was 10.1 ±0.6 mg/dl, and mean P levels of thenewborns was 6.2±1 mg/dl. Serum 25(OH)D values were highin mother who used vitamin D supplementation (P=0.02), PTHvalues were high and osteocalcine values were low in motherswho did not used vitamin D supplementation (P=0.02 andP=0.03, respectively). PTH values were low in newbornswhose mothers did not received vitamin D supplementation(P=0.004). 25(OH)D values were high in mothers whoreceived Ca supplementation (P=0.009). SOS values ofnewborns were 3127±107 (range, 2900-3389), and mean Zscores were 0.3±0.7 (range, -1.4 - 2.6).DISCUSSION AND CONCLUSION: Significant correlationwas observed between the SOS scores and Ca and ALP valuesof the newborns. Assessment of the structure of bone withquantitative ultrasound is a noninvasive and practical method.

Anne ve Term Bebeklerin Vitamin D ve Kalsiyum Metabolizmasının Değerlendirilmesi ve Bebeklerin Kemik Gücünün Kantitatiif Ultrason ile Tayini

Öz:

GİRİŞ ve AMAÇ: Yetersiz D vitamin alımı kemik mineralizasyonunu ve döngüsünü olumsuz etkilemektedir. Gebelikte annenin kemik döngüsü üzerindeki değişiklikler fetusun kemik mineral içeriğinde değişikliğe neden olmaktadır. Bu çalışmada fetal kemik minerilizasyonu üzerinde belirleyici olan D vitamin metabolizmasını etkileyen faktörler, biyokimyasal kemik göstergeleri ve yenidoğanlarda kantitatif ultrason ile değerlendirilen kemik yapısı arasındaki ilişkinin saptanması amaçlanmıştır. YÖNTEM ve GEREÇLER: Celal Bayar Üniversitesi Tıp Fakültesi Hastanesinde doğan 90 term bebek ve annesi çalışmaya alındı. Serum kalsiyum, fosfor, alkalen fosfataz, kemik alkalen fosfataz, 1,25(OH)2D, 25(OH)D, paratiroid hormone ve osteokalsin düzeyleri ölçüldü. Yaşamın ilk 96 saati içinde kantitatif ultrason cihazı ile tibial ölçümleri yapıldı. BULGULAR: Annelerin ortalama 25(OH)D ve 1,25(OH)2D düzeyleri normal sınırlarda saptandı. Yenidoğanlarda ölçülen ortalama Ca düzeyleri ortalama 10.1 ±0.6 mg/dl, P düzeyleri 6.2±1 mg/dl saptandı. D vitamini desteği almayan annelerde serum 25 (OH)D değerleri yüksek (p = 0.02), D vitamini desteği almayan annelerde PTH değerleri yüksek ve osteokalsin değerleri düşük bulundu (sırasıyla P = 0.02 ve p = 0.03). Anneleri D vitamini desteği almayan yenidoğanlarda PTH değerleri daha düşüktü (P= 0.004). Ca takviyesi yapılan annelerde 25 (OH) D değeri yüksekti (P = 0.009). Yenidoğanların SOS değerleri 3127 ± 107 (2900-3389), ortalama Z skoru 0.3 ± 0.7 (-1.4 - 2.6) idi. TARTIŞMA ve SONUÇ: Yenidoğanların SOS skorları ile Ca ve ALP değerleri arasında anlamlı korelasyon gözlendi. Kemik yapısının kantitatif ultrason ile değerlendirilmesi, invaziv olmayan ve pratik bir yöntemdir.
