Filter by:Vitamin D deficiency is highly prevalent in the UK. Research shows that vitamin D enhances the immune system and may help protect against chest infections that can cause wheezing illness or worsen asthma symptoms. The Department of Health recommends a dose of 10 micrograms of vitamin D/day to prevent severe vitamin D deficiency in children. However, many studies have reported that this dose is not enough to raise plasma 25(OH)D concentration to the levels most likely to prevent against worsening of asthma symptoms. Such studies suggest that 25 micrograms of vitamin D/day. This dose is safe but its effects on vitamin D blood levels have not yet been specifically tested in children with asthma/wheeze. This study is designed to determine the optimal oral daily vitamin D supplementation dose to treat vitamin D deficiency in children with asthma or preschool wheeze. Over the 6-month course of the study, participants will meet with the study team four times in clinic or in their own home and will be contacted by telephone five times. Children will be asked to give a drop of blood via a fingerprick to test their vitamin D level and a sample of nasal epithelial lining fluid for measurement of inflammatory markers on three separate occasions.
The purpose of this study is to determine whether extra fine formoterol/beclomethasona are more effective in the treatment of asthmatic crisis when added to conventional treatment compared with conventional treatment alone.
