Capillary leakage is the pathophysiological hallmark of severe dengue, and ultrasound has established as a sensitive tool for its early detection. However, evidence in the pediatric population remains limited. The aim of this study was to identify the presence of capillary leakage detected by ultrasound and its associations in children with dengue. Methods: Observational\/descriptive\/cross-sectional\/retrospective study conducted in patients between 6 months and 14 years old with confirmed dengue and warning signs or severe dengue, treated at the Hospital Universitario del Valle in Cali, Colombia, between July 2019 and June 2020. Ultrasound examinations were performed and interpreted by radiologists following an institutional standardized protocol. Associations with capillary leakage were evaluated using the chi-square test and their respective OR and 95% CI. Results: A total of 132 children were included. Ultrasound capillary leakage was identified in 95.5%, mainly ascites (83.3%), pleural effusion (46.2%), hepatomegaly (40.9%), and vesicular thickening (39.4%). Associated factors were belonging to school\/adolescent group (OR = 13.52; 95% CI = 1.41\u2013646.51; p = 0.0031), elevated alanine aminotransferase (OR = 11.06; 95% CI = 1.32\u201394.82; p = 0.0007), and aminotransferase levels grades C\u2013D (OR = 6.87; 95% CI = 0.82\u201354.59; p = 0.0110). Thrombocytopenia and hypoalbuminemia were common. Three deaths (0.9%) occurred in the initially confirmed cohort prior to ultrasound-based inclusion, all of whom presented multiple risk factors for capillary leakage. Conclusions: In this cohort ultrasound showed high sensitivity for detecting capillary leakage in pediatric dengue and was associated with school-age\/adolescents and liver involvement. Its systematic use could improve early identification of severe forms and optimize clinical management in resource-limited settings.<\/jats:p>","DOI":"10.3390\/children13010089","type":"journal-article","created":{"date-parts":[[2026,1,7]],"date-time":"2026-01-07T08:26:56Z","timestamp":1767774416000},"page":"89","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Capillary Leakage on Ultrasound in Children with Dengue"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2663-8753","authenticated-orcid":false,"given":"Mar\u00eda Teresa","family":"Guti\u00e9rrez-Arcos","sequence":"first","affiliation":[{"name":"Hospital Universitario del Valle, Universidad del Valle, Cali 760026, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4062-5326","authenticated-orcid":false,"given":"Carlos Alberto","family":"Velasco-Ben\u00edtez","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Universidad del Valle, Cali 760026, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6430-0905","authenticated-orcid":false,"given":"Daniela Alejandra","family":"Velasco-Su\u00e1rez","sequence":"additional","affiliation":[{"name":"Gastrohnup Research Group, Universidad del Valle, Cali 760026, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,7]]},"reference":[{"key":"ref_1","first-page":"e28916","article-title":"Efficacy of Dengue Vaccines in the Prevention of Severe Dengue in Children: A Systematic Review","volume":"14","author":"Foucambert","year":"2022","journal-title":"Cureus"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"350","DOI":"10.1016\/S0140-6736(18)32560-1","article-title":"Dengue","volume":"393","author":"Horstick","year":"2019","journal-title":"Lancet"},{"key":"ref_3","doi-asserted-by":"crossref","unstructured":"Moras, E., Achappa, B., Murlimanju, B.V., Naveen, G.M., Holla, R., Madi, D., D\u2019Souza, N.V., and Mahalingam, S.
