These are some photos of Liam before, during and after his 2nd Bone Marrow Transplant for HLH also know as Hemophagocytic Lymphohistiocytosis, a life-threatening immunodeficiency. In patients with primary HLH, cells of the immune system, principally T cells and NK cells, don’t work properly to destroy infected or damaged cells as they should. Because of this, the immune system becomes overstimulated and over activated. The immune system then begins to damage the patient’s own tissues and organs, including the bone marrow, the liver and the brain.
