Studies on strongyloidiasis prevalence are often heterogenous and mainly performed in adults in endemic countries. We retrospectively enrolled 2633 children referred to a tertiary care hospital in Italy between 2009 and 2020 and tested for S. stercoralis infection. Sixty-one (2.3%) had a positive serology and for 55 of them, clinical and epidemiological information were available. Thirteen cases (24%) were diagnosed in Italian children without history residency or travel to foreign countries, while the remaining were internationally adopted or migrant children. Seropositive patients were mostly asymptomatic, and often eosinophilia was the only sign of strongyloidiasis. Sero-reactivity to Toxocara canis was found in 1\/3 of patients. Ivermectin was used in 37 (75.5%) treated patients. A significant reduction of eosinophil levels and IgG titer was seen after treatment. Our study confirms that strongyloidiasis is usually asymptomatic in children. However, due to the ability of the parasite to cause a life-long infection together with the risk of a severe form in case of immunosuppression, it is important to identify and treat infected children. Special consideration should be reserved to high-risk groups, such as immigrants and international adoptees, where screening for S. stercoralis is indicated. However, the study highlights that sporadic cases of autochthonous strongyloidiasis in Italy may occur. Therefore, pediatricians should be aware of this condition, which is often under-recognized.<\/jats:p>","DOI":"10.3390\/microorganisms9091905","type":"journal-article","created":{"date-parts":[[2021,9,8]],"date-time":"2021-09-08T10:12:03Z","timestamp":1631095923000},"page":"1905","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Strongyloidiasis in Children Outside the Tropics: Do We Need to Increase Awareness?"],"prefix":"10.3390","volume":"9","author":[{"given":"Elisabetta","family":"Venturini","sequence":"first","affiliation":[{"name":"Infectious Diseases Unit, Meyer Children\u2019s University Hospital, 50139 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lara","family":"Fusani","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, University of Florence, 50121 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonia","family":"Mantella","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University of Florence, 50121 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leila","family":"Bianchi","sequence":"additional","affiliation":[{"name":"Infectious Diseases Unit, Meyer Children\u2019s University Hospital, 50139 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0295-6877","authenticated-orcid":false,"given":"Alberto","family":"Antonelli","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University of Florence, 50121 Florence, Italy"},{"name":"Microbiology and Virology Unit, Careggi University Hospital, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5950-4965","authenticated-orcid":false,"given":"Carlotta","family":"Montagnani","sequence":"additional","affiliation":[{"name":"Infectious Diseases Unit, Meyer Children\u2019s University Hospital, 50139 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena","family":"Chiappini","sequence":"additional","affiliation":[{"name":"Infectious Diseases Unit, Meyer Children\u2019s University Hospital, 50139 Florence, Italy"},{"name":"Department of Health Sciences, University of Florence, 50121 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5377-7118","authenticated-orcid":false,"given":"Michele","family":"Spinicci","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University of Florence, 50121 Florence, Italy"},{"name":"Referral Centre for Tropical Diseases of Tuscany, Infectious and Tropical Diseases Unit, Careggi University Hospital, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9758-1523","authenticated-orcid":false,"given":"Alessandro","family":"Bartoloni","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University of Florence, 50121 Florence, Italy"},{"name":"Referral Centre for Tropical Diseases of Tuscany, Infectious and Tropical Diseases Unit, Careggi University Hospital, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gian Maria","family":"Rossolini","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University of Florence, 50121 Florence, Italy"},{"name":"Microbiology and Virology Unit, Careggi University Hospital, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0892-8404","authenticated-orcid":false,"given":"Lorenzo","family":"Zammarchi","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University of Florence, 50121 Florence, Italy"},{"name":"Referral Centre for Tropical Diseases of Tuscany, Infectious and Tropical Diseases Unit, Careggi University Hospital, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7912-3366","authenticated-orcid":false,"given":"Luisa","family":"Galli","sequence":"additional","affiliation":[{"name":"Infectious Diseases Unit, Meyer Children\u2019s University Hospital, 50139 Florence, Italy"},{"name":"Department of Health Sciences, University of Florence, 50121 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Hotez, P.J., Aksoy, S., Brindley, P.J., and Kamhawi, S.
