Function in leukocyte recruitment from the peripheral circulation to sites of inflammation within tissue. -> It is designed to hamper movement of potentially damaging immune cells from the bloodstream, across the blood-brain barrier and across the intestinal barrier. 19 Tysabri & Multiple Sclerosis 20 - Autoimmune chronic inflammatory disease of the CNS characterized by ongoing inflammation, which results in neuronal demyelination and multifocal lesions.

Symptoms : abdominal and rectal pain, diarrhea (with blood, glair or not), anal fissure, fistulas, weight loss, abces around the anal area. 32 Crohn’s disease • Mechanism : Chronic gut inflammation caused by an abnormal immune response against normal intestinal bacteria (loss of tolerance). Characterized by persistent recruitment of leukocytes into gut tissue. Α-4-integrin = transmenbranary protein. Expressed on leukocytes, participating in adhesion and extravascular leakage of leukocytes. 33 Cell 138, August 7, 2009 ©2009 Elsevier Inc. Tysabri® • Humanized monoclonal antibody against α4-integrin => Natalizumab blocks leukocyte migration from the blood vessels to sites of inflammation. • Generally reserved for patients with moderate to severe Crohn’s disease that is refractory to other forms of medical therapy. • Approved in the USA but not in Europe, prescription and deliverance are taking part of the TOUCH® program. 34 August 2010 ■ Volume 41 Number 8 ■ LABMEDICINE Tysabri® : adverse effects o Progressive Multifocal Leukoencephalopathy o Hypersensitivity reactions o Immunosuppression – Infections o Hepatotoxicity o Most common AEs : headache, fatigue, arthralgia, urinary tract infection, lower respiratory tract infection, gastroenteritis, vaginitis, depression, pain in extremity, abdominal discomfort, diarrhea, and rash. 35 Crohn’s disease treatments Salicylic derivatives: Pentasa®, Rowasa® , Fivasa®.
