Can high ferritin levels predict acute asthma attacks in children?
Research shows that high ferritin levels are associated with acute asthma attacks in children. A study found that children having an acute attack had significantly higher ferritin levels than those in remission. This suggests ferritin might be a useful marker for predicting these events.
What the research says
Other research indicates that vitamin D supplementation does not improve lung function or reduce inflammation markers in children with asthma 1. Additionally, childhood asthma is linked to a higher risk of obstructive sleep apnea, which may complicate the clinical picture 2. Early-life exposures like prenatal cleaning product use are also linked to asthma development 3.
What to ask your doctor
- How do my child's ferritin and eosinophil levels compare to the ranges seen in studies?
- Could high ferritin levels be warning signs of an upcoming asthma attack for my child?
- What other factors, like sleep apnea or early-life exposures, might be contributing to my child's asthma?
- Is vitamin D supplementation recommended for my child given the current evidence?
