ViDES Trial (Vitamin D Extra Supplementation)

July 13, 2023 updated by: Maria del Mar Romero López, The University of Texas Health Science Center, Houston

Randomized Trial of Enteral Vitamin D Supplementation in Infants < 28 Weeks Gestational Age or <1000 Grams Birth Weight

The objective of the study is to compare supplementation with vitamin D at 800 IU/day to usual care for the first 28 days after birth with respect to 25 (OH) vitamin D levels and indicators of likely or plausible effects of vitamin D supplementation on the function or structure of the lung, bones, immune system, and brain in extremely premature (EP) infants who are <28 weeks gestational age (GA) or <1000 grams of birth weight (BW). The study results will be analyzed as intention to treat Bayesian analyses (Frequentist analyses will also be performed).

Description

Inclusion Criteria:

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Usual care plus placebo
Infants will receive placebo (normal saline) in the first 28 days after birth. Care will be unaffected and provided based on the judgment of the attending neonatal faculty and NICU policies and routine practices. When the infant receives about 120 to 160 mL/kg/day of fortified milk at 24 kcal/ounce, the infant will receive supplementation with 400 IU/day of vitamin D as usual care.
Placebo is normal saline, given in the first 28 days after birth, prepared to have the same volume and appearance as vitamin D, which is a clear odorless solution.
Other Names:
  • Normal saline
Care will be unaffected and provided based on the judgment of the attending neonatal faculty and NICU policies and routine practices. When the infant receives about 120 to 160 mL/kg/day of fortified milk at 24 kcal/ounce, the infant will receive supplementation with 400 IU/day of vitamin D as usual care.
Experimental: Usual care plus vitamin D supplementation
Infants will receive cholecalciferol 800 IU/day in the first 28 days after birth, given enterally four times per day (0.5mL per dose = 200 IU) until the infant is provided 400 IU/day (when feedings reach about 120 -160 mL/kg/day). At that point the study cholecalciferol will be reduced to 400 IU/day for a total supplementation of 800 IU/day.
Care will be unaffected and provided based on the judgment of the attending neonatal faculty and NICU policies and routine practices. When the infant receives about 120 to 160 mL/kg/day of fortified milk at 24 kcal/ounce, the infant will receive supplementation with 400 IU/day of vitamin D as usual care.
800 IU/day Vitamin D supplementation until 400 IU/day are provided as part of usual care (started when infants receive full feedings of about 120-160 mL/kg/day). At that point the intervention becomes a supplement of 400 IU/day above that given with usual care. In this way all infants in the intervention group receive 800 IU/day of vitamin D total supplementation in the first 28 days after birth with feedings.
Other Names:
  • Cholecalciferol
