What are parasitic eosinophilic diseases?

Pulmonary infiltrates with eosinophilia with parasites (ascaris, strongyloides...) When eosinophils present in lungs with no parasites this suggests an immunologic mechanism. GI symptoms dominate, respiratory symptoms include cough, wheezing and resolves with Rx directed at the parasite. Most serious one is filarial worm Wuchereria bankrofti and Burgia in india, africa or south america. Intense inflammation by microfilariae (cough, dyspnea, weight loss...) Rx is diethylcarbamazine (may lead to fibrosis or chronic bronchitis with chronic respiratory failure)
