Article	Clinical picture	Diagnostic tests	Treatment	Outcome
Del Giudice et al. (2002)	Intense non-productive cough	Lab: 10% eosinophils, normal IgE RI: ill-defined pulmonal reticulonodular infiltrates BAL: eosinophilic alveolitis Serology: negative Stool culture: negative	Oral thiabendazole 25 mg/kg twice daily for 10 days; oral corticosteroids 1 mg/kg daily	After 5 days: normalized peripheral eosinophilia and symptoms.
Lee et al. (2003)	No pulmonary symptoms	Lab: 35% eosinophils, serum IgE 1020 IU/mL, clonorchis specific IgG 0.27. RI: solitary pulmonary nodule, migrating nodular densities BAL: 25% eosinophils Sputum cytology: eosinophilia Stool examination: clonorchis sinensis eggs Lung biopsy: eosinophilic infiltration Bronchoscopy: normal	Oral praziquantel	Normalized peripheral eosinophilia. No signs of recurrence after 1 year follow-up.
Sator et al. (2007)	Cough and dyspnea	Lab: 33% eosinophils RI: local pulmonal infiltrate BAL: 79% eosinophils Serology: negative Stool and sputum examination: negative Bronchoscopy: normal	Oral methylprednisolone 40 mg daily, in decreasing dosage	Normalized peripheral eosinophila and cleared chest X-rays after 6 months. One month later, recurrence of symptoms and patient eventually died of another condition.
Meta-Jevtovic et al. (2008)	Low grade fever, shortness of breath, cough and reduced exercise tolerance	Lab: eosinophilia RI: pulmonary eosinophilic infiltrates Lung biopsy: changes associated with Löffler’s syndrome	Oral corticosteroids	Marked improvement of symptoms.
Turhan et al. (2008)	Headache, sore throat, cough	Lab: 14% eosinophils Stool examination: Strongyloides stercoralis	Oral albendazole	Improvement of symptoms and negative stool examinations .
Schaub et al. (2002)	No pulmonary symptoms	Lab: eosinophilia RI: migratory pulmonary infiltrates	Oral albendazole 400 mg on 5 consecutive days and a single dose of oral praziquantel 3600 mg	Resolved peripheral eosinophilia and pulmonary infiltrates
Tokojima et al. (2004)	High fever and fatigue	Lab: increased IgE level, no eosinophilia RI: ‘ground glass opacities’ in the right lung field BAL: high proportion of eosinophils ELISA: Ascaris suum	Oral albendazole	Clearance of symptoms
Tan et al. (2010)	Dyspnea, wheezing and chest discomfort	Lab: Leucocytosis, 19.1% eosinophils Blood gas: hypoxemia RI: reticulonodular pulmonary infiltrates Echocardiogram: normal Stools: negative	Oral mebendazole Oral albendazole Intravenous hydrocortisone Oxygen supplementation	Complete remission
