Leukocyte apheresis is a medical device therapy (selective granulocyte/monocyte adsorptive {GMA} apheresis; GMDN[1] code: 47306) for the treatment of inflammation of the colon. It works by removing from the blood a group of white blood cells called activated leukocytes[2] that play a key role in the inflammatory stages of ulcerative colitis (UC).[3] Selectively reducing these cells in the blood helps to reduce inflammation in the colon.[4] Leukocyte apheresis can help UC patients with chronic, grumbling disease who are either unsuitable for, intolerant of, or failing on medicines described above.[5]
