NCT01210521

Brief Summary

The purpose of this study is to determine the effects of vitamin D3 on severe asthmatic patients. Vitamin D3 may alter the response of these patients to conventional steroid therapy, making them more responsive to the latter form of treatment. Patients will be treated daily with an oral dose (2,000 IU) of vitamin D3 for one month and their clinical and serological parameters, and immune function, will be evaluated. Results from pre- and post-vitaminD3 treatment will be compared.

Outcome Measures

Primary Outcomes (1)

  • Pulmonary Function Test

    A pulmonary function test or spirometry, measures lung function by determining the volume and flow of air that can be inhaled or exhaled. FEV1is determined.

    Six months

Secondary Outcomes (1)

  • Concentration of Interleukin 10(IL-10),in serum.

    One year

Study Arms (2)

Prior to intervention with Vitamin D

NO INTERVENTION

Patients will be analyzed for clinical, serological and immunological parameters before starting the interventional drug, Vitamin D.

Vitamin D Intervention

ACTIVE COMPARATOR

Patients will be analyzed for clinical, serological and immunological parameters after one month taking Vitamin D.

Drug: Vitamin D

Interventions

Vitamin D, (2000IU) will be administered orally, once a day, for one month.

Vitamin D Intervention

You may qualify if:

  • Definition of Severe Asthma by American Thoracic Society Consensus (2000). Major Characteristics
  • In order to achieve control to a level of mild-moderate persistent asthma:
  • Treatment with continuous or near continuous (\>50% of year) oral corticosteroids
  • Requirement for treatment with high-dose inhaled corticosteroids:
  • Drug Dose (µg/d) Dose (puffs/d)
  • Beclomethasone dipropionate. \> 1,260. \> 40 puffs (42 µg /inhalation).
  • \> 20 puffs (84 µg/inhalation)
  • Budesonide \> 1,200 \> 6 puffs
  • Flunisolide \> 2,000 \> 8 puffs
  • Fluticasone propionate \> 880 \> 8 puffs(110µg), \>4puffs(220 µg)
  • Triamcinolone acetonide \> 2,000 \> 20 puffs
  • Minor Characteristics
  • Requirement for daily treatment with a controller medication in addition to inhaled corticosteroids, e.g., long-acting β-agonist, theophylline, or leukotriene antagonist
  • Asthma symptoms requiring short-acting β-agonist use on a daily or near daily basis
  • Persistent airway obstruction (FEV1,80% predicted; diurnal PEF variability \>20%)
  • +4 more criteria

You may not qualify if:

  • Vitamin D resistant rickets, chronic renal failure, hypercalcemia (secondary to hyperparathyroidism or malignancy), Chronic Obstructive Pulmonary Disease, severe malabsorption syndrome, sarcoidosis, patients taking cardiac glycosides for cardiac arrythmias.
  • Pregnant or nursing women, and smoking patients will be excluded.
