Platelet transfusion refractoriness (PTR) represents a therapeutic challenge, often resulting from alloimmunization against HLA antigens or the \u03b1IIb\u03b23 complex.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We report the case of a patient with type I GT, who presented with recurrent mucosal hemorrhages and chronic anemia requiring repeated transfusions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>By the age of 8 years, the patient developed transfusion refractoriness, with hemorrhagic episodes unresponsive to platelet transfusions. Immunologic investigations revealed anti-HLA and anti-\u03b1IIb\u03b23 antibodies. At 14\u2009years of age, a severe hemorrhagic episode with rapid hemoglobin decline was successfully managed with recombinant activated factor VII (rFVIIa).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Management of PTR in GT represents a major clinical challenge, frequently associated with anti-HLA or anti-\u03b1IIb\u03b23 antibodies. In high-resource settings, transfusion strategies are guided by antibody specificity: HLA-compatible or human platelet antigen\u2013compatible platelets are used for patients with anti-HLA or anti\u2013human platelet antigen antibodies, respectively, while rFVIIa is reserved for individuals with anti-\u03b1IIb\u03b23 antibodies. In LMIC such as Tunisia, prevention of alloimmunization through systematic leukoreduction is essential. When PTR occurs, donor selection by crossmatching, when feasible, and judicious use of rFVIIa for life-threatening hemorrhage remain key therapeutic options.<\/jats:p>\n
