Löffler’s syndrome is a disease in which eosinophils accumulate in the lung in response to a parasitic infection. The parasite can be Strongyloides stercoralis, Dirofilaria immitis or Ascaris which can enter the body through contact with the soil. The symptoms of Löffler’s syndrome include those of a parasitic infection such as irritable bowel syndrome, abdominal pain and cramping, skin rashes and fatigue. The Löffler’s syndrome itself will cause breathlessness, coughing as well as a fever.
In 1909 a man named H. French first described the condition. Then in 1932 Wilhelm Löffler drew attention to the disease in cases of eosinophilic pneumonia caused by the parasites Ascaris lumbricoides,Strongyloides stercoralis and the hookwormsAncylostoma duodenale and Necator americanus. Finally in 1943 the condition was called Tropical eosinophilia by RJ Weingarten, and later officially named Löffler’s syndrome. The most well-known case of Löffler’s syndrome was in a young boy from Louisiana. He arrived at the hospital reporting a high fever after three days, as well as having rapid breathing. ”He was hospitalized and treated with supplemental oxygen, intravenous methylprednisolone, and nebulized albuterol.” The boy’s symptoms quickly subsided and upon further investigation it was discovered that the boy worked caring for pigs. A test was then performed on the pigs’ fecal matter and surrounding soil; it contained the parasite that had caused the boy’s ailment.
