OBJECTIVE: In the neonatal period, diseases such as respiratory distress syndrome, necrotizing enterocolitis, bronchopulmonary dysplasia, retinopathy of prematurity, intraventricular hemorrhage, patent ductus arteriosus hypoxic-ischemic encephalopathy, and hyperbilirubinemia are frequently seen, despite being differently affected by the gestational age. This study aims to examine the relationship between morbidities in the neonatal period and serum vitamin A and vitamin E levels.

PATIENTS AND METHODS: In this prospective cohort study, patients who were treated and followed up in the Neonatal Intensive Care Unit between August 2020 and September 2021 were evaluated.

RESULTS: 381 patients, 202 male (53%) and 179 female (47%), were included in the study. The mean birth weight was 2642.13±835.91 g (minimum 480 g, maximum 4285 g) and the mean gestational week was 35.3±3.8 (minimum 24 weeks, maximum 42 weeks). The weight of 332 patients (87.2%) was above 1500 g in whom there was a significant increase in respiratory distress, hypoxic-ischemic encephalopathy, and hyperbilirubinemia correlated with a decrease in the vitamin E levels (p=0.001, 0.02, and 0.001, respectively). In infants over 32 weeks of age, there was a significant increase in respiratory distress, hypoxic-ischemic encephalopathy, and hyperbilirubinemia correlated with a decrease in the vitamin E levels (p=0.001, 0.02, and 0.001, respectively). No significant relationship was found between vitamin A levels and neonatal morbidities regardless of the birth weight or gestational age.

CONCLUSIONS: We believe that our study may provide convenience to pediatricians and neonatologists in terms of the relationship between vitamin A and E levels and neonatal morbidities in neonates.
