Diagnosing GVHD through histopathology alone can be challenging due to overlap with other conditions. Tissue elafin immunohistochemistry (IHC) has shown potential as a diagnostic tool, but studies report conflicting results.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives:<\/jats:title>\n                    <jats:p>To examine the utility of elafin IHC in skin biopsies for accurate acute skin GVHD diagnosis in HSCT recipients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Consecutive allogenic HSCT recipients in a tertiary care centre in South India, who developed rash within the first 100 days post-HSCT during a 17-month period were recruited. Skin biopsies were taken on the day of rash and epidermal elafin IHC was done. Staining of &gt;50% of the epidermis was considered positive. The final diagnosis of skin GVHD was assigned using a composite criteria of clinical features, histopathology and response to treatment. We evaluated the accuracy of elafin IHC in GVHD diagnosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Sixty-eight skin biopsies from 58 patients (median age 14 years; range 1\u201353; 46 males) were analyzed. Median day of rash onset was 23.5 (range: 5\u201398). GVHD was confirmed in 45 (66.2%) episodes. Elafin IHC was positive in all GVHD and 9\/23 non-GVHD cases, six of which were engraftment syndrome. The sensitivity and specificity of elafin IHC were 100% and 58.3%, respectively. There was a significant correlation between positive elafin IHC and GVHD (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.0001).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Tissue elafin is a highly sensitive IHC marker for diagnosis of acute skin GVHD, including cases without classic histopathological findings.
