Ages Eligible for Study:   6 Years to 12 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Physician diagnosed asthmatics and they should fulfill at least two of the following three criteria:

    • A minimum of three clinic visits for acute asthma within 1 year
    • Two or more asthma-related hospital admissions within 1 year, or
    • Steroid dependency, as defined by either 6 months of oral or 1 year of inhaled corticosteroid use
  • Age: 6-14 years old. The age group of 6 to 14 years old was chosen for two reasons:

    1. Diagnostic accuracy of asthma is better in this age group as non-specific wheezers less than 6 years of age could be excluded.
    2. Child should be able to use a peak flow meter and perform spirometry tests.
  • A positive specific IgE or a positive skin prick test for at least one airborne allergen.

Exclusion Criteria:

  • Children with mild intermittent and mild persistent asthma.
  • Asthmatic children who are currently on immunotherapy or anti IgE.
  • Asthmatic children with concomitant other medical problems.
  • Children who are younger than 6 yrs or older than 14 yrs.
  • Children with history of early life injury to airways like premature birth (< 36 weeks) or home use of oxygen.
  • Children with vitamin D deficiency. Since these children may be randomized to the control group, they will be excluded for ethical reasons.
