Hemophagocytic lymphohistiocytosis (HLH), is an uncommon, life-threatening hyperinflammatory syndrome caused by severe hypercytokinemia with excessive activation of lymphocytes and macrophages due to a highly stimulated but ineffective immune process. We report a case of Hemophagocytic Lymphohistiocytosis in a 15 year old boy presenting with fever, lymphadenopathy and pancytopenia due to infection caused by Klebsiella Pneumoniae and Acinetobacter.

Introduction: Besides cytokine release syndromes (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS), immune effector cell-associated HLH-like syndrome (IEC-HS) is increasingly recognized across CAR-T recipients. This emergent and fatal syndrome is difficult to separate from other disorders during the early phase, and urgently requires more integrated diagnostic and therapeutic frameworks.
Areas Covered: Existing literature has pointed out the potential role of unbridled proliferation of cytotoxic T lymphocytes, lymphopenia of natural killing cells, and hypercytokinemia in triggering the IEC-HS.

Secondary hemophagocytic lymphohistiocytosis (HLH) syndrome, a fatal disorder characterized by NK/T-cell deficiency, cytokine storm, and organ damage, is rare in chronic lymphocytic leukemia (CLL). Ibrutinib, the first generation of irreversible Bruton's tyrosine kinase inhibitor, has been the first-line therapy for CLL. As an off-target effect, it can also block IL-2 inducible T-cell kinase (ITK), which is essential in maintaining normal NK and T-cell functions.

Hemophagocytic lymphohistiocytosis (HLH) is a severe disorder with poor clinical outcomes. Use of emapalumab, an IFN-γ inhibitor, enables primary HLH control in over 85 % of affected children. However, data on emapalumab use for Epstein-Barr virus-associated HLH (EBV-HLH) are limited.
