Löffler's syndrome or Loeffler's syndrome is a disease in which eosinophils accumulate in the lung in response to a parasitic infection. It was first described in 1932 by Wilhelm Löffler〔 〕 in cases of eosinophilic pneumonia caused by the parasites ''Ascaris lumbricoides'', ''Strongyloides stercoralis'' and the hookworms ''Ancylostoma duodenale'' and ''Necator americanus''. Although Löffler only described eosinophilic pneumonia in the context of infection, many authors give the term "Löffler's syndrome" to any form of acute onset pulmonary eosinophilia no matter what the underlying cause. If the cause is unknown, it is specified and called "simple pulmonary eosinophilia". Cardiac damage caused by the damaging effects of eosinophil granule proteins (ex. major basic protein) is known as Loeffler endocarditis and can be caused by idiopathic eosinophilia or eosinophilia in response to parasitic infection. == See also == *Eosinophilic pneumonia *Parasitic pneumonia *Pneumonia 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Löffler's syndrome」の詳細全文を読む スポンサード リンク
