Amino Acid Intake in Preterm Infants.
Nestle Nutrition Institute Workshop Series
|June 24, 2016
Summary
Early amino acid administration is crucial for extremely low-birth-weight infants receiving parenteral nutrition. Doses of 2.5 g/kg/day improve nitrogen balance, but higher intakes require further study.
Area of Science:
- Neonatalogy
- Pediatric Nutrition
- Intensive Care Medicine
Background:
- Extremely low-birth-weight infants often require parenteral nutrition.
- Amino acids are essential components for promoting growth and development.
- Postnatal growth restriction is linked to neurodevelopmental delays.
Purpose of the Study:
- To evaluate the benefits of early amino acid administration in extremely low-birth-weight infants.
- To determine optimal amino acid dosages for parenteral nutrition.
- To investigate the impact of amino acid intake on nitrogen balance and growth.
Main Methods:
- Review of existing literature on parenteral nutrition in extremely low-birth-weight infants.
- Analysis of studies investigating different amino acid dosages.
- Assessment of nitrogen balance and growth outcomes.
Main Results:
- Early amino acid administration shows significant benefits for nitrogen balance.
- A dosage of 2.5 g/kg/day of amino acids is superior to lower intakes.
- Evidence for benefits of amino acid intakes above 2.5 g/kg/day is inconclusive.
Conclusions:
- Early initiation of amino acid therapy is recommended for extremely low-birth-weight infants.
- 2.5 g/kg/day is an effective amino acid dose, but higher doses need more research.
- Further studies are needed to understand long-term outcomes of various amino acid intakes.

Amino acid biosynthesis is essential for cell growth, protein synthesis, and metabolic regulation. Cells generate essential and non-essential amino acids from metabolic intermediates to sustain vital biological functions. These intermediates originate from key metabolic pathways: glycolysis, the tricarboxylic acid (TCA) cycle, and the pentose phosphate pathway. Important precursors include α-ketoglutarate, pyruvate, oxaloacetate, phosphoenolpyruvate, and erythrose-4-phosphate, which...

Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.

Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

Proteins in the gastrointestinal tract typically come from food, but they can also originate from disintegrated cells or secreted enzymes. In the stomach, the enzyme pepsin breaks down these proteins into polypeptides. The fragments then move into the duodenum as a semi-fluid mass called chyme. Pancreatic proteases, such as trypsin and chymotrypsin, and intestinal brush border enzymes like carboxypeptidases further dismantle the polypeptides into tripeptides, dipeptides, and free amino acids.

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
