Abstract

Purpose: Retinopathy of prematurity (ROP) is a proliferative vascular disease which affects premature newborns and occurs during vessel development. The pathogenesis of ROP is complex and includes oxidative damage to the developing retina. The aim of this study was to evaluate the relationship of ROP with serum vitamin A levels and clinical parameters in infants with a gestational age of ≤32 weeks and birth weight of ≤1500 grams. Ma te ri al and Met hod: Newborns admitted to Newborn Intensive Care Unit within the first 24 hours of life, with gestational age ≤ 32 weeks, birth weight ≤1500 grams, without any major congenital anomalies, inborn error of metabolism or prior history of blood/blood products transfusion were included in the study. The patients were divided into two groups, ROP (+) and ROP (-), according to the presence of ROP at any stage. Serum vitamin A levels and gender, type of delivery, birth weight, gestational age, duration of hospitalization and oxygen supply, multiple gestation, preeclampsia, PDA, sepsis and intraventricular hemorrhage of the groups were compared with Mann-Whitney U and chi-square tests. Re sults: The mean gestational age of these infants was 29.2±2.0 weeks and the mean birth weight was 1287±197 grams. ROPwas diagnosed in 48% of infants and the mean serum vitamin A level was 0.56±0.45 μmol/L. In 44 cases (84%), vitamin A level was determined low (

Özet

Amaç: Prematüre retinopatisi (ROP), düşük doğum ağırlıklı ve erken doğan bebeklerde görülen retinal damarların anormal proliferasyonuna bağlı oluşan proliferatif vasküler hastalıktır. ROP patogenezi karmaşıktır ve gelişen retinaya serbest radikallerin oksidatif hasarı patogenezde rol oynayabilir. Çalışmada gebelik yaşı ≤32 hafta ve doğum ağırlığı ≤1500 gram prematüre bebeklerde vitamin A düzeyi ve klinik parametrelerin ROP gelişimi ile ilişkisini araştırmak amaçlanmıştır. Gereç ve Yöntem: Yenidoğan Kliniği’ne yaşamın ilk 24 saati içinde başvuran, gebelik yaşı ≤32 hafta, doğum ağırlığı ≤1500 gram,major konjenital anomalisi ve doğumsal metabolik hastalık bulunmayan, kan veya kan ürünü ile transfüze edilmemiş olgularda serum vitamin A düzeyi yüksek basınçlı lipid kromatografi yöntemi ile ölçüldü. Bir aylık olduklarında ROP açısından muayene edilen olgular,herhangi bir evrede ROP saptanan ve ROP saptanmayan olmak üzere iki gruba ayrıldı. Her iki grubun serum vitamin A düzeyi ile cinsiyet, doğum şekli, doğum ağırlığı, gebelik yaşı, yatış ve oksijen tedavisi süresi, çoğul gebelik, preeklampsi, PDA, sepsis ve intrakranial kanama arasındaki istatistiksel ilişkiyi Mann-Whitney U ve ki-kare testleri ile karşılaştırıldı. Sonuçlar: Çalışma grubunu oluşturan ortalama gebelik yaşları 29,2±2,0 hafta, ortalama doğum ağırlıkları 1287±197 gram toplam 52 preterm bebeğin %48’ inde herhangi bir evrede ROP saptanırken, ortalama serum vitamin A düzeyi 0,56±0,45 μmol /L olarak bulundu. Kırkdört olguda (%84) vitamin A düzeyi normal değerin altında (
