Abstract

Hemophagocytic lymphohistiocytosis (HLH) is a result of an abnormal activation of immune cells (T lymphocytes, natural killer cells, and macrophages) resulting in cytokine overproduction and immune destruction of cells, eventually resulting in multiorgan failure. Genetic causes are responsible for primary hemophagocytosis, but malignancies, infections, and autoimmunity underlie most of the secondary cases. We present an unusual case of a patient with AIDS and disseminated Kaposi sarcoma who was commenced on highly active antiretroviral therapy (HAART) but developed HLH secondary to immune reconstitution inflammatory syndrome (IRIS). We report this case to highlight the difficulty in managing this patient given the complex interplay of immunosuppression due to AIDS, immune reconstitution following initiation of HAART, and immune overdrive manifesting as HLH.
