Aug 5, 2022 · Eosinophilic pneumonia can affect anyone at any age, with a wide range of causes that include smoking, allergic reaction and parasitic roundworm disease. Left untreated, some cases of eosinophilic pneumonia may lead to severe complications like respiratory failure.

Eosinophilic pneumonia is a disease in which an eosinophil, a type of white blood cell, accumulates in the lungs. These cells cause disruption of the normal air spaces (alveoli) where oxygen is extracted from the atmosphere. Several different kinds of eosinophilic pneumonia exist and can occur in any age group.

Eosinophilic pneumonia comprises a group of lung diseases in which eosinophils (a type of white blood cell) appear in increased numbers in the lungs and usually in the bloodstream. Certain disorders, drugs, chemicals, fungi, and parasites may …

Mar 5, 2025 · Acute eosinophilic pneumonia is an eosinophilic lung disease which can mimic community-acquired pneumonia or present with acute lung injury 10: The true incidence is unknown due to under-diagnosis and under-reporting. Studies of military personnel indicate approximately 10 per 100,000 person-years.

Acute Eosinophilic Pneumonia (AEP) is a rare inflammatory lung disease, which can cause younger adults to develop respiratory failure requiring intubation. This is an important disorder to be aware of because, if treated aggressively with steroid, patients will rapidly recover.

Acute eosinophilic pneumonia causes an acute febrile illness of short duration (usually < 7 days). Symptoms are nonproductive cough, dyspnea, malaise, myalgias, night sweats, and pleuritic chest pain. Signs include tachypnea, fever (often > 38.5° C), and bibasilar inspiratory crackles and, occasionally, rhonchi on forced exhalation.

Aug 1, 2023 · Although both AEP and chronic eosinophilic pneumonia (CEP) are characterized by eosinophilic infiltration of the pulmonary parenchyma, these disorders are clinically distinct . The clinical features and management of idiopathic acute eosinophilic pneumonia will be …

Apr 21, 2024 · Acute and chronic eosinophilic pneumonia (AEP and CEP) include a group of rare interstitial lung diseases characterized by peripheral blood eosinophilia, increased eosinophils in bronchoalveolar lavage fluid, or eosinophilic infiltration of lung parenchyma. AEP is characterized by rapid onset, fast response to steroid treatment, and no relapse.

Acute eosinophilic pneumonia (AEP) is an uncommon, acute-onset form of eosinophilic lung disease which varies in severity. Though poorly understood, the pathogenesis of AEP likely varies depending on the underlying cause which may include smoking, inhalation exposure, medication, and infection. [1] .
