Simple pulmonary eosinophilia
Pulmonary infiltrates with eosinophilia; Loffler syndrome; Eosinophilic pneumonia; Pneumonia - eosinophilic
Simple pulmonary eosinophilia is inflammation of the lungs from an increase in eosinophils, a type of white blood cell.
Causes
Most cases of this condition are due to an allergic reaction from:
- A medicine, such as a sulfonamide antibiotic or nonsteroidal anti-inflammatory drug (NSAID)
-
Infection with a fungus such as
Aspergillus fumigatus
or
Pneumocystis jirovecii
Aspergillus fumigatus
Pulmonary aspergilloma is a mass caused by a fungal infection. It usually grows in lung cavities. It can also appear in the brain, kidney, or other...
Pneumocystis jirovecii
Pneumocystis jiroveci pneumonia is a fungal infection of the lungs. The disease used to be called Pneumocystis carini or PCP pneumonia.
-
A parasite, including the roundworms
Ascariasis lumbricoides
,
or
Necator americanus
, or the
hookworm
Ancylostoma duodenale
Ascariasis lumbricoides
Ascariasis is an infection with the parasitic roundworm Ascaris lumbricoides.
Hookworm
Hookworm infection is caused by roundworms. The disease affects the small intestine and lungs.
In some cases, no cause is found.

- Rash
-
Shortness of breath
Shortness of breath
Breathing difficulty may involve:Difficult breathingUncomfortable breathingFeeling like you are not getting enough air
-
Wheezing
Wheezing
Wheezing is a high-pitched whistling sound during breathing. It occurs when air moves through narrowed breathing tubes in the lungs.
Symptoms can range from none at all to severe. They may go away without treatment.
Exams and Tests
The health care provider will listen to your chest with a stethoscope. Crackle-like sounds called rales may be heard. Rales suggest inflammation of the lung tissue.
A complete blood count (CBC) may show increased white blood cells, particularly eosinophils .
Complete blood count
A complete blood count (CBC) test measures the following:The number of red blood cells (RBC count)The number of white blood cells (WBC count)The tota...
Eosinophils
An absolute eosinophil count is a blood test that measures the number of white blood cells called eosinophils. Eosinophils become active when you ha...
Chest x-ray usually shows abnormal shadows called infiltrates. They may disappear with time or reappear in different areas of the lung.
Chest x-ray
A chest x-ray is an x-ray of the chest, lungs, heart, large arteries, ribs, and diaphragm.
A bronchoscopy with washing may show a large number of eosinophils.
Bronchoscopy
Bronchoscopy is a test to view the airways and diagnose lung disease. It may also be used during the treatment of some lung conditions.
A procedure that removes the stomach contents ( gastric lavage ) may show signs of the Ascaris worm or another parasite.
Gastric lavage
Gastric suction is a procedure to empty the contents of your stomach.
Treatment
If you are allergic to a medicine, your provider may tell you to stop taking it. Never stop taking a medicine without first talking with your provider.
If the condition is due to an infection, you may be treated with an antibiotic or anti-parasitic medicine.
Sometimes, anti-inflammatory medicines called corticosteroids are given.
Outlook (Prognosis)
The disease often goes away without treatment. If treatment is needed, the response is usually good. But, the disease can come back, especially if the condition does not have a specific cause and needs to be treated with corticosteroids.
Possible Complications
A rare complication of simple pulmonary eosinophilia is a severe type of pneumonia called acute idiopathic eosinophilic pneumonia.
Pneumonia
Pneumonia is a breathing (respiratory) condition in which there is an infection of the lung. This article covers community-acquired pneumonia (CAP). ...
When to Contact a Medical Professional
See your provider if you have symptoms that may be linked with this disorder.
Prevention
This is a rare disorder. Many times, the cause cannot be found. Minimizing exposure to possible risk factors, such as certain medicines or parasites, may reduce the chance of developing this disorder.
