Complete Response to Donor Lymphocyte Infusion for Primary Hemophagocytic Lymphohistiocytosis Relapse after Allogeneic Hematopoietic Cell Transplantation.
Introduction: Primary hemophagocytic lymphohistiocytosis (HLH) is a hyper-inflammatory disorder characterized by dysregulation of inflammatory cells and cytokine signaling. Although first-line treatment consisting of immunosuppressive therapy and allogeneic hematopoietic cell transplantation (HCT) is often curative, it remains unknown whether any effective therapies exist for disease relapse/progression after HCT.
Case presentation: Here we present a case of a 29-year-old male with primary HLH who failed HLH-94 protocol and subsequently underwent myeloablative HCT. Disease relapse occurred at 9 months following HCT, and donor lymphocyte infusion (DLI) was initiated as salvage therapy. The patient subsequently achieved durable long-term disease-free survival following a DLI, without significant treatment-related complications.
Conclusion: To our knowledge, this represents the first case demonstrating the efficacy of DLI for relapsed primary HLH.
期刊介绍：
''Acta Haematologica'' is a well-established and internationally recognized clinically-oriented journal featuring balanced, wide-ranging coverage of current hematology research. A wealth of information on such problems as anemia, leukemia, lymphoma, multiple myeloma, hereditary disorders, blood coagulation, growth factors, hematopoiesis and differentiation is contained in first-rate basic and clinical papers some of which are accompanied by editorial comments by eminent experts. These are supplemented by short state-of-the-art communications, reviews and correspondence as well as occasional special issues devoted to ‘hot topics’ in hematology. These will keep the practicing hematologist well informed of the new developments in the field.
