Mild and Severe Asthma May Be 2 Diseases
The authors of a study reported recently in the European Respiratory Journal have concluded that severe asthma and mild asthma may be different conditions with different inflammatory processes. The study, conducted by scientists across Europe, evaluated 321 patients, 158 with mild-to-moderate asthma and 163 with severe asthma. The results of the study showed that both groups had very different levels of key chemicals in their blood. Also, whereas more men suffered from asthma, women were 4 times as likely to suffer from severe asthma. Individuals with mild-to-moderate asthma were able to control their symptoms with low doses of inhaled corticosteroids. Very few with severe asthma, however, were able to have their symptoms treated despite being treated with heavier doses of drugs.
