Some facts about Parasitic Helminth infections
– most common in far east or South America
– Mod of infection is through ingestion of snail, crayfish, crab and other small crustaceans
– common sx are recurrent hemoptysis, fever, streaky small infiltrate on chest xr, eosinophilia
– can see pleural effusion in up to 60% cases
– treat with PRAZIQUANTEL or triclabendazole

Praziquantel has an unknown mechanism of action but has been effective in treating flatworm infections

Think of a parasitic helminth infection in patient with eosinophilia and hemoptysis, especially if they are from South America and/or East Asia.
