Application of blood and immunodeficiency gene detection in the diagnosis of hemophagocytic lymphohistiocytosis patients

Hemophagocytic lymphohistiocytosis (HLH) is caused by excessive activation of lymphocytes and histiocytes, secretion of a large number of cytokines, which eventually leads to fatal inflammatory damage, characterized by damages to multiple organs, rapid disease progression and high mortality. HLH can be divided into primary and secondary HLH according to etiology. Primary HLH includes familial HLH (FLH) and immunodeficiency-related HLH. The former can be classified into five types: FHL1 –FHL5. The latter include Chediak–Higashi syndrome 1, Glicelli syndrome II, Hermansky–Pudlak syndrome II, X-linked lymphoid tissue proliferation syndrome 1 and X-linked lymphoproliferative syndrome 2, and interleukin (IL)-2-mediated T-cell kinase deficiency-related lymphoblastic syndrome.
