Asthma is a chronic (long-term) lung disease that inflames and narrows the airways. Asthma causes recurring periods of wheezing A (a whistling sound when you breathe), chest tightness, shortness of breath, and coughing. The coughing often occurs at night or early in the morning. Asthma affects people of all ages, but it most often starts during childhood. In the United States, more than 25 million people are known to have asthma. Asthma in most babies is a reaction to a trigger, often an allergen such as pet saliva, skin or urine, dust mites, or pollen. Airborne irritants such as cigarette smoke and mould spores can also be
The guts of children who are at high risk for asthma display low levels of four specific bacterial species when they are three months old, scientists have discovered. The finding could lead to a test that can more accurately predict which children might develop asthma, but the upshot of the study is even bigger. The scientists think their study could lead to a microbe-based treatment that might prevent the development of asthma in infants.
For the study, Finlay and colleagues looked for four types of bacteria in stool samples form more than 300 babies at 3 months and one year old of age. The researchers found that 22 children with low levels of these bacteria at age 3 months also had low levels at age 1 year.These 22 children are at the highest risk of developing asthma, and eight have been diagnosed with the respiratory disease so far. In the first 100 days of life, gut makeup influences the immune response that causes or protects kids from asthma
Testing for these bacteria in infants might help identify children who have a high risk of developing asthma, Turvey said. "These children could be followed and treated more quickly if they end up with asthma
