Review of the Literature

Two independent investigators (GVR and RPR) searched the literature to identify cases of Strongyloides HS in patients with asthma. Eligibility criteria were: (1) case reports including individuals with asthma exacerbation who tested positive for S. stercoralis by means of any fluid or solid specimen (stool, bronchial secretions); and (2) diagnosis of Strongyloides HS based on microscopic visualization of the larvae from bronchial secretions or through histopathology. Abstracts were reviewed in PubMed, EBSCO, LILACS, and SciELO. MeSH search terms included: "Strongyloides" AND "asthma"; "Strongyloides stercoralis" AND "asthma"; "Strongyloidiasis" AND "asthma". Also, we conducted a secondary search of the literature through Google/Google Scholar and reviewed previous references. Reports in English, French, or Spanish languages were included. Figure 1 presents the abstract screening process. Reports that met the eligibility criteria were analyzed in detail. The authors evaluated those articles and any discrepancy was solved by consensus. Data were collected in case forms and stored in a spreadsheet.
