Intervención / Tratamiento
Descripción detallada
The first phase of the study consisted of a cross-sectional examination of a cohort of 119 asthmatic patients, who had at least one year regular follow-up in our respiratory clinic, and were not receiving any vitamin D supplementation.
In the second phase patients with vitamin D deficiency (25-OH D values below 20 ng/ml), were recruited in a one year longitudinal study, during which they received vitamin D supplementation. The study started and ended in late autumn-winter season when, at our latitude, sun exposure is lowest. Symptoms, spirometry and number of exacerbations were recorded during both study phases.

Periodo de tiempo |
|---|---|---|
|
Relationship between serum 25-hydroxide (OH) vitamin D level and asthma exacerbations (number/year= unscheduled visits for worsening symptoms, increase in therapy)
Periodo de tiempo: one year
|
119 consecutive asthmatic patients underwent serum vitamin D (25-OHD) and lung function assessment.
Their medical records were retrospectively reviewed, to gain information on disease exacerbations during the 12 months preceding study entry.
The relationship between baseline 25-OH vitamin D and number of exacerbation was investigated

Effect of vitamin D supplementation in patients with 25-OH vitamin D < 20 ng/ml on asthma exacerbations (number/year= unscheduled visits for worsening symptoms, increase in therapy)
Periodo de tiempo: One year
|
55 asthmatic patients with 25-OH vitamin D below 20 ng/ml underwent supplementation with cholecalciferol for one year (intramuscular 100,000 IU, followed by oral 5000 IU weekly plus 400 IU daily for one year).
Number of exacerbations were recorded during the year of supplementation and compared with the data recorded during vitamin D deficiency

Relationship between serum 25-OH vitamin D level and airway obstruction (evaluated by spirometry: one second forced expiratory volume, FEV1 l/sec, vital capacity (VC) and FEV1/VC%)
Periodo de tiempo: one year
|
119 consecutive asthmatic patients underwent serum vitamin D (25-OHD, ng/ml) and lung function assessment.
Their medical records were retrospectively reviewed, to gain information on lung function tests (forced expiratory volume in 1 second, FEV1, and vital capacity, VC) during the 12 months preceding study entry.
The relationship between baseline 25-OH vitamin D and airway obstruction (FEV1 and FEV1/VC%) was investigated
