Background and study aims
Survival rates of babies born prematurely are increasing, but long-term consequences of pre-term birth may persist throughout life. The ideal growth of a premature newborn is considered to be the same as the intrauterine growth of the fetus. However, a premature infant experiences a high level of stress and inadequate nutrition during the hospitalization period despite recommended high nutrient intake. Morbidity during the early neonatal period has a negative impact on growth and neurodevelopment. Optimization of nutrition should improve long-term outcomes. The aim of this study is to look for reliable nutrition assessment markers and evaluate the role of early nutrition on growth, body composition and neurodevelopmental outcomes.

Who can participate?
Very low birth weight (less than 1500 g) newborns born in the Hospital of Lithuanian University of Health Sciences Kauno klinikos can participate in this study, if both parents sign the informed consent. The infant will participate in the study until 12 months corrected gestational age, i.e. until 12 months starting count from the due date. Newborns with congenital anomalies will not be included.

What does the study involve?
The study is non interventional. All newborns receive the same care and feeding regimens according to their clinical condition. Mother’s own milk is analyzed for protein, carbohydrates, fat and calories weekly, intravenous and oral intake is calculated daily. Standard measures, such as weight, length and head circumference is checked weekly as well as detailed measurements of upper arm, thigh circumference, lower leg length and skinfold on 4 sites. Blood specimens for hormones affecting growth and adipose tissue accumulation (1 ml of blood) is drawn at 1, 2, 4, 6, 8 weeks or until discharge. Neurodevelopment will be assessed using standardized scales at 12 months corrected gestational age.

What are the possible benefits and risks of participating?
Since there is no intervention, no particular benefit will be from the enrollment. There is a small risk of bleeding, infection and short-term pain during the blood draw. Pain relief measures are always applied before blood draw. Also there are very small doses of additional radiation during DXA imaging.

Where is the study run from?
The study is running in the Hospital of Lithuanian University of Health Sciences Kauno klinikos.

When is the study starting and how long is it expected to run for?
May 2018 to September 2024

Who is funding the study?
The study is funded by Hospital of Lithuanian University of Health Sciences Kauno klinikos.

Scientific titleThe role of early nutrition on metabolic markers and hormones, growth and neurocognitive development of very low birth weight newborns
Study acronymRENHGD
Study objectivesThe aim of this study is to determine the relationship between early nutrition (evaluating amounts of parenteral and enteral intakes of protein and calories during hospitalisation period), metabolic markers and hormones (glucose, insulin, IGF-1, IGFBP-3, leptin, ghrelin, adiponectin), growth, body composition, morbidity and neurodevelopmental outcomes among VLBW infants.
Ethics approval(s)Approved 28/02/2018, Kaunas Regional Biomedical Research Ethics Committee (A. Mickevičiaus str. 9, LT-44307 Kaunas (406 room); kaunorbtek@lsmuni.lt; +370 615 81669), ref: BE-2-12
Health condition(s) or problem(s) studiedGrowth and neurodevelopment of very low birth weight (<1500 g) newborns
InterventionCord blood sample for glucose, insulin, IGF-1, IGFBP-3, leptin, ghrelin, adiponectin and DNA extraction is drawn after birth of very low birthweight newborns. Daily nutritional data are evaluated, composition of mother's own milk or donor milk is analyzed weekly, general anthropometric measures (weight, length, head circumference) as well as detailed anthropometric measures ( mid-upper-arm circumference, mid-thigh circumference, lower leg lenght and 4 site skinfold) are performed weekly. 1 ml of blood at 1, 2, 4, 6 and 8 weeks after birth and 12 months corrected gestational age is drawn for glucose, insulin, IGF-1, IGFBP-3, leptin, ghrelin, adiponectin testing. BUN is a part of routine nutritional screening and these data as well as morbidity such as sepsis, necrotizing enterocolitis, bronchopulmonary dysplasia, retinopathy of prematurity are collected from medical records. At discharge and 12 months corrected gestational age DXA analysis for body composition is performed. At 12 months corrected gestational age neurodevelopment is assessed using Bayley II scale.
Intervention typeNot Specified
Primary outcome measure1. Growth restriction at discharge measured using Fenton growth charts
2. Body composition at discharge measured using DXA analysis.
Secondary outcome measures1. At 12 months corrected gestational age neurodevelopment is assessed using Bayley II scale.
