What is eosinophilic asthma and how to manage it
Eosinophilic asthma is a subtype of asthma characterized by increased amounts of eosinophils, a type of white blood cell, in the airways. This condition affects a significant number of asthma patients and requires specialized management. It is rare and more common in adults; typical asthma remedies may not work on this subtype, making treatment more challenging. This article will explore the causes, signs, symptoms, and treatment options for eosinophilic asthma.
Causes
Some of the known causes and triggers of eosinophilic asthma include the following:
Allergens
Exposure to allergens is a common trigger for eosinophilic asthma. These allergens include pollen, dust mites, pet dander, mold spores, and certain foods. When individuals with eosinophilic asthma come into contact with these allergens, their immune system overreacts, leading to airway inflammation and asthma symptoms.
Environmental factors
Environmentally induced factors, such as air pollution and occupational exposure to certain chemical substances, can contribute to developing or exacerbating eosinophilic asthma. These factors can irritate the airways and trigger an immune response, increasing eosinophil levels and inflammation.
Genetic factors
There is evidence that genetics may play a role in developing eosinophilic asthma. Certain genetic variations and family history of asthma or allergies can increase the risk of developing this subtype.
Respiratory infections
Respiratory infections, such as viral or bacterial infections of the respiratory tract, can trigger or exacerbate eosinophilic asthma. These infections cause inflammation in the airways, leading to an immune response and potential eosinophilic activation.
Additionally, not all individuals with asthma will have eosinophilic asthma, as the condition has different subtypes and variations.
Signs and symptoms
Eosinophilic asthma presents similar symptoms to other forms of asthma, but it is characterized by increased eosinophilic inflammation in the airways. The common signs and symptoms include:
Wheezing
The narrowing of the airways leads to a characteristic wheezing sound during breathing.
Shortness of breath
Eosinophilic asthma can cause difficulty in breathing, especially during physical activities.
Coughing
Persistent and often dry coughing is a common symptom of eosinophilic asthma.
Chest tightness
Patients may experience a sensation of tightness or pressure in the chest.
Recurrent asthma attacks
Eosinophilic asthma is often characterized by frequent asthma flare-ups, which may require professional intervention.
Treatment
The management of eosinophilic asthma involves a combination of strategies aimed at reducing airway inflammation, preventing asthma attacks, and improving overall respiratory function. Some standard treatment options include:
Biologic therapies
Biologic remedies, such as monoclonal antibodies, target specific molecules involved in eosinophilic asthma, reducing eosinophil levels and minimizing inflammation.
Allergen immunotherapy
If specific allergens trigger eosinophilic asthma, allergen immunotherapy may be recommended to desensitize the immune system and reduce allergic reactions.
Environmental modifications
Avoiding triggers, such as allergens and pollutants, can help manage eosinophilic asthma. This includes maintaining clean indoor environments and using air purifiers if necessary.
Identifying triggers, managing symptoms, and reducing airway inflammation are vital to effective treatment. If you experience symptoms suggestive of eosinophilic asthma, consult a healthcare professional for a comprehensive evaluation and personalized management plan. Remember to ask about any food and lifestyle changes that may need to be made too for a speedier recovery.
