Pulmonary eosinophilia
Pulmonary eosinophilia
Pulmonary eosinophilia describes a situation where there are increased numbers of eosinophils in the lung airways and parenchyma. This is generally associated with a blood eosinophilia.Causes of pulmonary eosinophilia
- Churg-Strauss syndrome
- allergic bronchopulmonary aspergillosis (ABPA)
- Loffler's syndrome
- eosinophilic pneumonia
- hypereosinophilic syndrome
- tropical pulmonary eosinophilia
- drugs: nitrofurantoin, sulphonamides
- less common: Wegener's granulomatosis
Loffler's syndrome
- transient CXR shadowing and blood eosinophilia
- thought to be due to parasites such as Ascaris lumbricoides causing an alveolar reaction
- presents with a fever, cough and night sweats which often last for less than 2 weeks.
- generally a self-limiting disease
Acute eosinophilic pneumonia
- highly responsive to steroids
Tropical pulmonary eosinophilia
- associated with Wuchereria bancrofti infection
