This retrospective study, conducted between January 2012 and December 2021, aimed to compare demographic data, clinical characteristics and management appropriateness of adult patients from H\u00f4pital Universitaire de Bruxelles-Erasme and Centre Hospitalier Universitaire Saint-Pierre who had a positive serology for Strongyloides stercoralis. Serology results were classified as weakly positive (WP) or positive (P), and the two groups were compared. Qualitative and continuous data were expressed as numbers and medians, respectively, and compared using Fisher\u2019s exact or Wilcoxon\u2013Mann\u2013Whitney tests, with a p-value &lt; 0.05 considered statistically significant. A total of 358 patients (50% females) were included, with a median age of 52 (IQR: 40\u201363): 225 (62.8%) had WP and 133 (37.2%) had P results. Overall, 217\/358 (60.6%) of the patients had at least one comorbidity, and 52\/358 (14.5%) had an immunosuppressive factor. In total, 120\/358 (33.5%) were symptomatic and 160\/352 (45.5%) had blood eosinophilia. Only 51\/358 (14.2%) benefitted from appropriate clinical management. Severe complications occurred in 17\/358 (4.7%) patients, with two deaths (0.6%). This first Belgian study about strongyloidiasis shows that, despite low rates of severe complications and mortality, significant treatment delays were observed, requiring future improvement and monitoring.<\/jats:p>","DOI":"10.3390\/microorganisms14081781","type":"journal-article","created":{"date-parts":[[2026,8,12]],"date-time":"2026-08-12T12:53:48Z","timestamp":1786539228000},"page":"1781","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Strongyloidiasis Diagnosed by ELISA in Brussels: A Bicentric Retrospective Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-6571-5934","authenticated-orcid":false,"given":"Juliette","family":"Becu","sequence":"first","affiliation":[{"name":"Clinic of Infectious Diseases, H\u00f4pital Universitaire de Bruxelles (HUB), Universit\u00e9 Libre de Bruxelles (ULB), 1070 Brussels, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8995-6230","authenticated-orcid":false,"given":"Charlotte","family":"Martin","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases, Centre Hospitalier Universitaire Saint-Pierre, Universit\u00e9 Libre de Bruxelles (ULB), 1000 Brussels, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8623-2165","authenticated-orcid":false,"given":"Sigi","family":"Van den Wijngaert","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Laboratoire Hospitalier Universitaire de Bruxelles-Universitair Laboratorium Brussel (LHUB-ULB), 1000 Brussels, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9307-7418","authenticated-orcid":false,"given":"Delphine","family":"Martiny","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Laboratoire Hospitalier Universitaire de Bruxelles-Universitair Laboratorium Brussel (LHUB-ULB), 1000 Brussels, Belgium"},{"name":"Faculty of Medicine and Pharmacy, University of Mons (UMONS), 7000 Mons, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carine","family":"Truyens","sequence":"additional","affiliation":[{"name":"Laboratory of Parasitology, Faculty of Medicine, ULB Center for Research in Immunology (UCRI), Universit\u00e9 Libre de Bruxelles (ULB), 1070 Brussels, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maya","family":"Hites","sequence":"additional","affiliation":[{"name":"Clinic of Infectious Diseases, H\u00f4pital Universitaire de Bruxelles (HUB), Universit\u00e9 Libre de Bruxelles (ULB), 1070 Brussels, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,12]]},"reference":[{"key":"ref_1","unstructured":"(2023, January 18).
