Löffler syndrome on a Louisiana pig farm.

摘要: Loffler syndrome, a fulminant eosinophilic pneumonitis associated with the larval migratory phase of human parasites, is rarely reported in United States. A previously healthy 8-year-old male was hospitalized tachypnea, cough, hypoxemia, and fever one week's duration. History revealed exposure to pigs on his family's farm southernmost Louisiana, where patient responsible for cleaning farm's pigpens. His fingernails were soiled extremely short, edge nail bed exposed secondary onychophagia. Laboratory evaluation demonstrated peripheral eosinophilia (39%), pulmonary (86%), high total IgE, diffuse reticulonodular lung opacities, mixed obstructive restrictive function pattern. Systemic corticosteroids initiated acute respiratory insufficiency produced rapid clinical improvement. Serum Ascaris-specific IgE markedly elevated he treated albendazole. An extensive other infectious allergic etiologies negative. site visit family laboratory investigation coordinated Louisiana Animal Disease Diagnostic at LSU. Ascaris suum eggs detected fresh pig feces soil immediately surrounding pens. Ascariasis should be considered even absence travel history, especially swine raising areas that are endemic pigs, such as southeastern Onychophagia highly probable mechanism zoonotic fecal-oral transmission this case, habits could lead continual reinfection. effective treating patient's compromise due syndrome.
