17. Respiratory Infections: Eosinophilia in the Lungs
Respiratory infections, both acute and chronic, can lead to an increase in eosinophils. This section focuses on the types of respiratory infections that commonly cause eosinophilia, how these infections affect eosinophil levels, and the implications for treatment.
Certain respiratory infections, particularly those of a viral or fungal nature, can stimulate an eosinophilic response. This response is part of the body’s attempt to fight off the infection but can lead to complications like bronchitis or pneumonia.
Infections like bronchitis or certain types of pneumonia can be associated with eosinophilia. These conditions can cause symptoms like coughing, wheezing, and difficulty breathing, exacerbated by the eosinophilic response.
Diagnosing eosinophilia due to respiratory infections involves respiratory assessments, imaging studies, and blood tests. Treatment focuses on managing the infection with appropriate medications, such as antivirals or antifungals, and addressing the eosinophilic response, often with corticosteroids.
Treatment strategies need to be individualized, considering the specific respiratory infection and the extent of eosinophilia. This often involves a combination of infection-specific treatments and supportive care to manage symptoms and eosinophil levels. (17)
