Objectives
Narrative objectives1
We will determine if vitamin D3 peroral administration of 800IU/day for two months can prevent asthma attack in children (6 – 15 years old) for the next 4 months (total 6 months observation), by conducting a double blind randomized controlled clinical trial.

Results
BACKGROUND:
In our prior randomized trial on preventing influenza, asthma attacks as a secondary outcome occurred less often in the vitamin D group than the placebo group. We aimed to clarify whether low-dose, short-term vitamin D supplementation, in addition to standard treatments, improves control of childhood asthma.
METHODS:
We conducted a randomized, double-blind, placebo-controlled trial comparing vitamin D3 supplements (800 IU/day) with placebo for 2 months in schoolchildren with asthma. The primary outcomes were frequency and severity of asthma judging from changes of asthma control levels defined by the Global Initiative for Asthma (GINA) by collaborating doctors at 2 and 6 months.
RESULTS:
Japanese schoolchildren with asthma (n=89) were randomly assigned to receive vitamin D (n=54) or placebo (n=35). At 2 months, GINA asthma control was significantly more improved in the vitamin D group compared with the placebo group (P=0.015). Childhood asthma control test (CACT) scores, a secondary outcome, were also significantly (P=0.004) improved in the vitamin D group compared with the placebo group at 2 months, and differences remained significant (P=0.012) at 6 months. The proportion of patients with a peak expiratory flow rate <80% predicted was significantly less in the vitamin D group (8/54: 15%) than the placebo group (12/35: 34%) at 6 months (P=0.032).
CONCLUSIONS:
Low-dose, short-term vitamin D supplementation in addition to standard treatment may improve levels of asthma control in schoolchildren. This article is protected by copyright. All rights reserved.
