Phase 3
Not yet recruiting
Conditions
Very Low Birth Weight Infant
Nutritional Deficiency
Interventions
Other: Sterile Water
Registration Number
NCT06433674
Lead Sponsor
University of Tennessee
Brief Summary

The goal of this clinical trial is to observe for changes in rate of weight gain in the very low birth weight (VLBW) infants by adding an enteral Zinc supplement of 1 mg/kg/day of elemental zinc. The main question it aims to answer:

• Does an enteral Zinc supplement of 1 mg/kg/day increase rate of weight gain in VLBW infants Researches will compare the experimental group to a placebo group to see if there is a statistical difference in rate of weight gain between the two groups

* Once the participants have reached 100 ml/kg/day of enteral feeds. The participants will be randomized to one of two groups. The treatment group will receive \~1 mg/kg/day of elemental enteral Zinc, and the control group to receive similar amount of enteral sterile water put in a colored syringe. The Zinc Supplement would be Zinc Sulfate. The primary team would otherwise be managing the patient's feeding using our hospital's feeding protocol. As long as the patient is tolerating 100 ml/kg/day of enteral feeds, the Zinc Supplement will continue until 36 weeks postmenstrual age (PMA) or hospital discharge, whichever comes first.

* The participants will have three Zinc levels measured: once prior to Zinc Supplementation, once at around the four week mark, and once at the completion of therapy.

Detailed Description

This is a prospective, single center, randomized, double blinded, placebo controlled clinical trial. The goal of this clinical trial is to observe for changes in rate of weight gain in the VLBW infants by adding an enteral Zinc supplement of 1 mg/kg/day of elemental zinc. The main question it aims to answer:

• Does an enteral Zinc supplement of 1 mg/kg/day increase rate of weight gain in VLBW infants Researches will compare the experimental group to a placebo group to see if there is a statistical difference in rate of weight gain between the two groups

* Once the participants have reached 100 ml/kg/day of enteral feeds. The participants will be randomized using sealed envelopes. The subjects will be randomly selected to one of two groups. The treatment group will receive \~1 mg/kg/day of elemental enteral Zinc, and the control group to receive similar amount of enteral sterile water put in a colored syringe. The Zinc Supplement would be Zinc Sulfate. Only the pharmacy will know which patient is receiving the Zinc Sulfate and which patient is receiving the placebo. The primary team would otherwise be managing the patient's feeding using our hospital's feeding protocol. As long as the patient is tolerating 100 ml/kg/day of enteral feeds, the Zinc Supplement will continue until 36 weeks PMA or hospital discharge, whichever comes first.

* The participants will have three Zinc levels measured: once prior to Zinc Supplementation, once at around the four week mark, and once at the completion of therapy.

Primary Outcome Measures
NameTimeMethod
Rate of weight gainat hospital discharge or 36 weeks PMA whichever comes first.

The primary outcome would be the rate of weight gain in grams/kg/day

Secondary Outcome Measures
NameTimeMethod
Lengthat hospital discharge of 36 weeks PMA whichever comes first

This secondary outcome would be the rate of length gain in cm/day

Head Circumferenceat hospital discharge of 36 weeks PMA whichever comes first

This secondary outcome would be the rate of head circumference gain in cm/day

Zinc levelComparing the initial zinc level to the four week zinc level as well as the zinc level at 36 weeks or discharge whichever comes first

This secondary outcome would be looking for a statically significant difference in zinc level
