The difference between asthma and eosinophilic lung disease is with eosinophilic lung disease you have a higher number of eosinophils in your blood, lung tissue, and coughed-up mucus (sputum).

With normal asthma you may also have other allergies that trigger the asthma such as from pollen or pet dander but with eosinophilic lung disease the allergies don't trigger it.

The difference between asthma and eosinphillic asthma are that people with eosinophilic asthma don't usually have triggers for the asthma such as pet dander or pollen.

With regular asthma the pollen, pet dander and other allergens can trigger the asthma but not usually with eosinphilic asthma.

With eosinophilic asthma you have a higher number of eosinophils in the blood, lung tissue and coughed up mucus or sputum.

One common sign of eosinophilic asthma is the presence of nasal polyps in the nose or sinuses.

The symptoms of eosinophilic asthma which include tightness in the chest, wheezing and shortness of breath.

The first line of treatment for eosinophilic asthma is inhaled and oral corticosteroids which work by reducing airway inflammation which leads to airway constriction and enables you to breathe easier.

People get eosinophilic asthma as a result of high levels of white blood cells called eosinophils that get in the airways of the lungs.

The purpose of the white blood cells is to fight infections and sometimes your immune cells over react and cause inflammation in the body including your lungs.

The new treatment for eosinophilic asthma is FASENRA which is a biologic that is designed to target and remove eosinophils which is a key cause of severe asthma.

Eosinophilic asthma is not the same as COPD although asthma is typically associated with Th2-mediated eosinophilic airway inflammation, in contrast to neutrophilic inflammation observed commonly in COPD

Also there is increasing evidence that the eosinophil may even play an important role in 10–40% of people with COPD.

Foods you should avoid with eosinophilic asthma are foods with cow's milk (dairy) and wheat.

The foods that most commonly cause an allergic reaction leading to EoE include milk, eggs, wheat, soy, peanuts or tree nuts and fish or shellfish.

In eosinophilic asthma, the numbers of eosinophils are increased in blood, lung tissue, and mucus coughed up from the respiratory tract (known as sputum).

The whole respiratory tract is involved in airflow obstruction from the sinuses to the small or distal airways.

Recovering from eosinophilic pneumonia takes around 1 month for most people for full recovery.

Doctors will usually also give corticosteroids to reduce symptoms and to help reduce inflammation.

Eosinophilic pneumonia is very rare and only accounts for approximately 2.5% of interstitial lung diseases.

It is idiopathic and can occur in any age group but is rarely observed in child.

The parasite that causes eosinophilic pneumonia is paragonimus, the lung fluke.

Helminthic infections are the most common parasitic diseases that produce eosinophilia.

Nematode infections account for the majority of patients with eosinophilia in tropical countries, especially in areas where filariasis, ascariasis and hookworm infection are endemic.

Eosinophilic pneumonia is a group of rare infections that affects the lungs.

A type of white blood cell builds up in the lungs and blood, causing inflammation and damage.

Causes include smoking, allergic reactions and parasitic infections.

Eosinophilia is associated with many disorders, limiting its usefulness as a diagnostic tool in screening expatriates for parasite infections.

In addition, only tissue-invasive helminthic parasites cause eosinophilia, which limits its general application as a screening tool for parasitic infections.

Eosinophilic pneumonia is a group of disorders that is characterized by an accumulation of eosinophilic infiltrates in the pulmonary parenchyma with or without peripheral blood eosinophilia.

These include a broad range of lung conditions that occur due to infectious or non-infectious causes.

Acute eosinophilic pneumonia: This type worsens quickly as your blood oxygen level falls.

Most people with AEP completely recover with treatment.

Chronic eosinophilic pneumonia: This type worsens slowly, over days or weeks.

If untreated, it may persist over weeks or months and result in severe symptoms.

Chronic eosinophilic pneumonia (CEP) is a rare disorder, accounting for approximately 2.5% of interstitial lung diseases.

It is idiopathic and can occur in any age group but is rarely observed in child.
