  Purpose

This trial objective is to assess whether doubling the daily intake of vitamin D improves serum vitamin D levels and serves as primary prevention of respiratory infections and asthma in premature infants.

This is a prospective randomized (1:1) double-blinded trial.

The study population will be randomized into two groups (1:1):

  • Intervention Group - 800 IU of Vitamin D once daily
  • Control Group - 400 IU of Vitamin D once daily Patients will be followed up for one year after randomization for serum Vitamin D levels and respiratory morbidity.

Condition Intervention
Other Preterm Infants
Vitamin D Deficiency
Bronchiolitis
Asthma
Pneumonia
Dietary Supplement: Vitamin D

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Prevention
Official Title: The Effect of Vitamin D Administration to Premature Infants on Vitamin D Status and Respiratory Morbidity During the First Year of Life

Primary Outcome Measures:
  • Improved serum vitamin D levels in the intervention group (receiving 800 IU daily) in comparison to the control group (receiving 400 IU daily) [ Time Frame: 12 months of age ]

Secondary Outcome Measures:
  • respiratory morbidity prevalence [ Time Frame: first year ]
    Reports given by the parents via questionnaire at 3, 6, 9 and 12 months.

  • respiratory morbidity prevalence [ Time Frame: first year ]
    Information collected from medical records containing the data of diagnosis or admission to pediatrics departments due to: bronchiolitis, wheezing, upper or lower respiratory tract infections, asthma and pneumonia

  • respiratory morbidity prevalence [ Time Frame: first year ]
    Information collected from medical records containing the data of medication consumption such as bronchodilators, inhaled corticosteroid, systemic corticosteroids (along with respiratory disease) and antibiotics (along with respiratory infection).

Arms Assigned Interventions
Experimental: Intervention Group
800 IU of Vitamin D once daily
Dietary Supplement: Vitamin D
also known as Cholecalciferol, is one of the two most important compounds within the group of Vitamin D. It can be ingested from the diet and from supplements. In this study it is pharmacologically acquired and referred to as Vitamin D
Control Group
400 IU of Vitamin D once daily, the standard of care
Dietary Supplement: Vitamin D
also known as Cholecalciferol, is one of the two most important compounds within the group of Vitamin D. It can be ingested from the diet and from supplements. In this study it is pharmacologically acquired and referred to as Vitamin D

Detailed Description:

The rational of this trial is that a daily supplementation of a double dose of Vitamin D (800 IU instead of 400 IU) to late premature infants during the first year of life will result in elevated Vitamin D serum levels and in an improvement in respiratory morbidity.

This randomized trial of vitamin D supplementation is planned to determine the optimal dose of daily vitamin D supplementation required to achieve sufficient vitamin D levels in preterm infants and to assess whether doubling the daily intake of vitamin D may serve as primary prevention of respiratory infections and asthma in premature infants.
