Eosinophilic asthma, a subtype of asthma, is a relatively uncommon condition that impacts approximately 8 to 10 percent of individuals in the United States [https]. Recent research has indicated that asthma is not a singular condition, but rather a diverse range of conditions with different causes and overlapping symptoms. Eosinophilic asthma specifically affects the entire respiratory tract, and its name stems from the increased presence of eosinophils in the lung tissue, sputum, and blood.
Eosinophilic Asthma vs Non-Eosinophilic Asthma
Eosinophilic asthma and non-eosinophilic asthma share similar symptoms but have distinct effects on the respiratory system. Eosinophilic asthma is characterized by inflammation in the airways caused by eosinophils, a type of white blood cell, leading to asthma symptoms. On the other hand, non-eosinophilic asthma is a result of a reaction involving various cells, excluding eosinophils.
Eosinophils: The Specialized White Blood Cells
Eosinophils are a type of specialized white blood cells that are produced in the bone marrow. These cells play a crucial role in various inflammatory processes, particularly in allergic reactions. Eosinophils are known for their beneficial functions, as they have the ability to trap substances and eliminate harmful cells such as bacteria and parasites. However, in certain situations, such as in the case of eosinophilic asthma, these cells can accumulate excessively, leading to harmful effects.
