Thymus and activation\u2010regulated chemokine (TARC) and squamous cell carcinoma antigen 2 (SCCA2) are biomarkers. This study examined how severity, defined by Patient\u2010Oriented Eczema Measure (POEM) score, correlates with TARC, SCCA2, total immunoglobulin E (IgE), and eosinophil counts in infantile AD (&lt;\u20092\u2009years), comparing their diagnostic performance and examining each biomarker's association with individual POEM items.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective study included 50 children aged &lt;\u20092\u2009years with newly diagnosed AD (March 2023\u2013November 2024). Patients were categorized as mild or moderate\u2010to\u2010severe disease based on POEM scores. Receiver operating characteristic (ROC) analyses were used to assess each biomarker's sensitivity and specificity for severity classification, and correlations with POEM's seven items were evaluated using Spearman correlations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      SCCA2 had the highest diagnostic accuracy for mild AD (area under the curve [AUC]\u2009=\u20090.708), while TARC had the best performance (AUC\u2009=\u20090.717) for moderate AD. Total IgE and eosinophil counts had AUC values at approximately 0.5. TARC showed stronger correlations (Spearman's rank correlation coefficient [\n                      <jats:italic>r<\/jats:italic>\n                      s]\u2009\u2265\u20090.4) with bleeding and flaking compared with SCCA2.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In children aged &lt;\u20092\u2009years with AD, TARC and SCCA2 were superior to total IgE or eosinophils in assessing severity.
