Abstract

Objectives: In this study, the relationship of cord blood Neutrophil Gelatinase-Associated Lipocalin (NGAL) with neonatal diseases was investigated. Methods: NGAL levels were measured in the cord blood of 180 babies born between 2015 and 2016. Patients were classified according to maternal diseases, neonatal diseases and demographic characteristics. Obtained data were compared with cord blood NGAL levels. Results: In our study, the mean NGAL levels were 1283.99 ng/mL in boys and 1306.52 ng/mL in girls. Umbilical cord blood NGAL levels of infants diagnosed with intrauterine growth retardation (1913.4±2833.5 ng/mL) and prolonged premature rupture of membranes (2594.2±2037.1 ng/mL) were found to be statistically high (p0.05). Conclusions: Neutrophil Gelatinase-Associated Lipocalin, may be useful as a diagnostic biomarker in the evaluation of maternal and neonatal diseases. However, studies on larger patient populations are needed.

Özet

Amaç: Respiratory syncytial virus (RSV) bütün dünyada infant ve çocuklarda yüksek mortalite ve morbidite ile seyreden alt solunum yolu enfeksiyonlarının majör sebebidir. Bu çalışmada amacımız hastanede yatan ve alt solunum yolu enfeksiyonu olan infant ve çocuklarda RSV enfeksiyonlarınıninsidansının araştırmak ve tanı yöntemi olarak direkt immunfloresan test ile ters transkripsiyon polimeraz zincir reaksiyonu (Reverse Transcription Polymerase Chain Recation; RT-PCR) testlerini karşılaştırmaktır. Yöntemler: Çalışmaya Ocak 2011 ve Ocak 2012 tarihleri arasında alt solunum yolu enfeksiyonu olup hastaneye yatırılan toplam 323 hastayı (0-15 yaş) dahil ettik. Floklueküvyon (Copan Diagnostics, Italy) ile alınan nazofaringeal sürüntü örneklerinde RSV antijenini direkt immunfloresan test (Argene SA, France) ile, RSV RNA varlığını ise in-housenested RT-PCR yöntemi ile araştırdık. Bulgular: Toplam 323 örneğin 95’inde (%29,4) RT-PCR ile RSV RNA, 88’inde (%27,6) ise direkt immunfloresan test yöntemi ile RSV antijen pozitifliği tespit ettik. Örneklerin 80’inini (%25) her iki yöntem ile pozitif, 220’sini (%68) ise her iki yöntem ile negatif bulduk. RT-PCR testine göre kıyasladığımızda direkt immunfloresan testinin sensitivitesini %84,2, spesifitesini %96,5, pozitif prediktif değerini %91 ve negatif prediktif değerini %93,6 bulduk. Sonuç: Çalışma grubunda RSV enfeksiyonlarının insidansının (%29,4) oldukça yüksek olduğunu tespit ettik. Sonuç olarak antiviral tedavinin erken başlanması ve nozokomiyal yayılımın azaltılması için %84 gibi yüksek sensitivite gösteren, daha hızlı bir test (2.5 saate karşılık 12 saat) olan direkt immunfloresan testinin ilk tanı testi olarak kullanılmasını ve test sonucu negatif bulunan örneklerin RT-PCR ile çalışılmasını öneriyoruz.
