News in now finally starting to inform the population in general that vitamin D can have a significant impact of the course of the disease. Here are a couple of articles from Web MD

4/23/09 Low Vitamin D Linked to Severe Asthma

My niece, a young four year old girl at the time, 2006, had very severe asthma. She was going to the emergency room one to two times per month. The mother found out about a study that was done in the UK about how steroids worked significantly better if the asthma sufferer had a higher level of vitamin D. The mother decided to supplement at 1500 IU of vitamin D3 per day which is within the guidelines of the NIH. In the four years since the child has only been to the emergency room one time during the first winter of supplementation.
This level of supplementation should have put the child’s serum 25(OH)D level above 50 ng/ml. As a rule of thumb the amount necessary for a child is about 35-40 IU’s of D3 per lb of body weight per day. At 40 lbs that would mean that she was getting 1500/40 = 37.5. The serum 25(OH)D levels in a sunny country are between 54 to 90 ng/ml. Since then the mother has increased the amount that she gives the child to try to maintain that range as the child grows. In general she seems to be much happier and healthier.
If your child has asthma, it is important to have the serum 25(OH)D level tested to be sure that is adequate to reduce inflammation. Get your doctor tuned into this if he is not already on board and you can make life for yourself and your child much more pleasant.
Vitamin D is significant in how it reduces inflammation in all parts of the body and in particular the organs.
