Abstract
Düşük total protein düzeyleri intravasküler kompartman hacmini ve kan basıncını düşürüp hayati organlara yeterli kan akışının bozarak ciddi olumsuz sonuç, mortalite ve morbiditelerin görülmesini kolaylaştırabilir. Çalışmamızda 32 hafta altında doğan prematüre bebeklerde doğumdaki total protein seviyesinin ciddi olumsuz sonuç, mortalite ve morbiditeler arasındaki ilişkisinin araştırması amaçlanmıştır. Çalışma prospektif olarak yapılmış ve çalışmaya 05.09.2019-30.11.2021 tarihleri arasında Bursa Uludağ Üniversitesi Tıp Fakültesi’nde doğmuş veya doğduktan sonraki ilk 24 saat içerisinde sevk alınmış ve major konjenital anomalisi olmayan hastalar dahil edilmiştir. Çalışmamıza göre total protein seviyesi ciddi olumsuz sonuç görülen grupta anlamlı olarak düşük bulunmuştur (p=0,013). Hastalara Score for Neonatal Acute Physiology (SNAP)-2 ve Perinatal Extension (SNAPPE)-2 skoru hesaplanmıştır. SNAPPE-2 skorunun ciddi olumsuz sonucu öngörmede en iyi belirteç olduğu bulunmuş ve SNAP-2 ve SNAPPE-2 skorlarının ciddi olumsuz sonucu öngörmede birbirilerinin yerine kullanılabileceği (p=0,280) fakat total protein seviyesi ve albumin seviyesinin SNAPPE-2 skorunun yerine kullanılamayacağı tespit edilmiştir (p=0,015 ve p=0,007). Hipoproteinemi gözüken grupta mortalitenin daha fazla görüldüğü bulunmuş (p<0,001) ve Receiver operating characteristic (ROC) analizi ile değerlendirildiğinde SNAPPE-2 skorunun mortaliteyi öngörmede en iyi belirteç olduğu ve SNAP-2 ve SNAPPE-2 skorlarının mortaliteyi öngörmede birbirilerinin yerine kullanılabileceği (p=0,086) fakat total protein seviyesi ve albumin seviyesinin SNAPPE-2 skorunun yerine kullanılamayacağı tespit edilmiştir (p=0,032 p=0,017). Hastalık ciddiyetini ve hastane içi ölüm riskini iii tahmin etmek için kullanılan mortalite skorları içinde fikir birliğine varılabilmiş olan objektif bir skorlama sistemi henüz mevcut değildir. Mikrovasküler sistemin dahil edildiği Akut Fizyoloji ve Kronik Sağlık Değerlendirmesi-III skorlama sistemi içinde albumin bileşenlerden biri olarak yer almaktadır. Fakat total protein seviyesinin yer aldığı bir skorlama sistemi bulunmamaktadır. Çalışmamıza göre hipoproteinemi; 32 hafta altında doğan prematüre bebeklerde RDS, HAPDA, IVK, BPD, NEK, hipotansiyon morbiditeleri ve mortalite ile ilişkili önemli bir belirteçtir. Sonuç olarak günümüzde YDYBÜ’de en sık kullanılan skorlama olan SNAPPE-2 skoruna total protein seviyesi eklenerek ciddi olumsuz sonuç, mortalite ve morbiditeleri gösterme gücü arttırılabilir
Low plasma protein levels may decrease the intravascular compartment volume and blood pressure and cause deterioration of adequate blood flow to vital organs, thus facilitating the occurrence of serious adverse outcomes, mortality and morbidities. These observations have led us to perform a study to determine the relationship between hypoproteinemia on first day of life and severe adverse outcomes, mortality and morbidities in infants born below <32 weeks gestation. This was a prospepective study conducted in the NICU of the Bursa Uludağ University Faculty of Medicine between September 2019 and December 2021. All the infants hospitalized in our neonatal intensive care unit (NICU) had a blood sample at 24 hours of life. Patients were exclude if the serum protein value on the first day of life was not avaible or if they had major congenital malformations. Serum total protein values were significantly different in infants who with severe adverse outcome (p=0,013). The median score value of SNAP-2 and SNAPPE-2 was calculated to be higher in infants with hypoproteinemia. SNAP-2 and SNAPPE-2 predicted severe adverse outcome significantly better than plasma protein levels and albumin levels (p=0,032 p=0,017), while no significant difference was seen with SNAP-2 (p=0,280) . Mortality occured higher in the group with hypoproteinemia (p<0,001). SNAP-2 and SNAPPE-2 predicted mortality significantly better than plasma protein levels (p=0,032 p=0,017) and albumin levels, while no significant difference was seen with SNAP-2 (p=0,086). v There is not yet an objective scoring system that can reach a consensus for mortality scores used to predict disease severity and mortality risk. Albumin is one of the components of the Acute Physiology and Chronic Health Assessment-III scoring system. But there is no scoring system that includes the plasma protein levels. Hypoproteinemia is an importent marker with among the morbidities respiratory distress syndrome (RDS), patent ductus arteriosus (HAPDA), intraventricular hemorrhage (IVK), bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC), hypotension and mortality. By adding a score created according to plasma protein level to the SNAPPE-2, which is currently used most frequently in the NICU, its power to indicate severe advers outcome and mortality can be increased.
