High Protein Diet for Premature Infants
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether a high-protein diet derived from human milk can improve growth and body composition in extremely premature infants weighing less than 1000 grams at birth. The goal is to determine if this diet enhances development compared to a standard protein diet, particularly in terms of lean body mass. Infants born very small, who have begun feeding by two weeks old, and are receiving exclusive human milk-based nutrition qualify as candidates for this trial. The findings could revolutionize nutrition management for some of the smallest and most fragile newborns. As an unphased trial, participation offers a unique opportunity to contribute to groundbreaking research that could transform nutritional care for vulnerable infants.
Do I need to stop my current medications for the trial?
The trial protocol does not specify whether participants must stop taking their current medications.
What prior data suggests that this high protein diet is safe for premature infants?
Research has shown that high-protein diets are generally safe for premature infants, but some considerations remain. Studies have found that protein intake up to 4.5 grams per kilogram per day is safe for infants weighing more than 1000 grams. However, less information exists about infants weighing less than 1000 grams, which is the focus of this trial.
Some studies suggest that very high protein levels might cause issues like acidosis (excess acid in the body) or uremia (waste buildup in the blood) in premature infants. These effects are rare but important to monitor.
Overall, while high-protein diets can support growth in preterm infants, careful monitoring of protein intake is crucial to avoid potential problems. This trial aims to find the right balance to help the smallest and most vulnerable babies grow well.12345Why are researchers excited about this trial?
Researchers are excited about exploring a high protein diet for premature infants because it could lead to better growth outcomes compared to the standard protein diet. Unlike traditional feeding regimens that provide 3.5 to 3.8 grams of protein per kilogram per day, this high protein approach aims for 4.2 to 4.5 grams, potentially enhancing muscle and bone development. The goal is to optimize the nutrition of these vulnerable infants, potentially leading to healthier growth trajectories and improved overall development.
What evidence suggests that a high protein diet is effective for improving growth and body composition in premature infants?
This trial will compare a high-protein diet with a standard protein diet for premature infants. Research has shown that a high-protein diet can improve growth in premature infants. Studies have found that babies receiving more protein tend to grow closer to expected standards. This diet is believed to aid in muscle development, benefiting overall growth. However, some research mentions possible side effects, such as excess acid in the body or waste buildup in the blood. Despite these concerns, the diet is generally considered safe and effective for babies weighing over 1000 grams. The goal is to find the right balance to promote growth without causing harm.12346

Are You a Good Fit for This Trial?
This trial is for extremely premature infants weighing between 500-1000 grams at birth, who are expected to survive until at least 36 weeks postmenstrual age. They must be able to start feeding within the first two weeks of life and can either be born at or transferred to the study institution within their first day of life.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- High Protein Diet
- Standard Protein Diet
Trial Overview
The study compares growth and body composition outcomes in preterm infants given a high protein human milk diet versus those on a standard protein human milk diet. It aims to determine if higher protein improves overall body composition, particularly lean mass.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Active Control
The intervention group will receive the same standard feeding regimen with the addition of extra milk fortification to give a high protein diet. Human milk will be prepared and analyzed in the same method as the control group. Based on the amount of protein in the milk, fortification of feeds with donor milk derived fortifier will be adjusted to reach an average of 4.2 to 4.5 g/kg/day. The diet will be continued until approximately 35 to 36 weeks PMA at which point a DXA scan will be performed. Infants will have 3 sets of labs. A serum blood urea nitrogen and creatinine as well as serum calcium, phosphorus, and alkaline phosphatase when the DXA is performed. Anthropometrics: weekly weight, length, and head circumference by trained research nurse.
Infants will receive a standard feeding regimen which consists of mother's own milk or donor human milk (DHM) with DHM derived fortifier. Once daily, a 24 hour batch of human milk is prepared for each infant (standard practice). A 2.5 mL sample will be analyzed for calories, protein, fat, and carbohydrates. Based on the amount of protein in the milk, fortification of feeds with donor human milk derived fortifier will be adjusted to reach an average of 3.5 to 3.8 g/kg/day of protein. Data will be recorded for milk analysis, nutrition, and infant growth. The diet will be continued until approximately 35 to 36 weeks postmenstrual age at which point a DXA scan will be performed. A serum blood urea nitrogen and creatinine as well as serum calcium, phosphorus, and alkaline phosphatase when the DXA is performed. Anthropometrics: weekly weight, length, and head circumference by trained research nurse.
