A positive clinical experience of a long-term treatment pattern with leukocyte apheresis and Adacolumn in ulcerative proctitis.

Abstract

Ulcerative proctitis (UP) is often involved in the diagnosis of inflammatory bowel disease (IBD). The increase of leukocytes and pro-inflammatory factors in peripheral blood and in the active forms, as well as the infiltration of neutrophils and monocytes/macrophages in the intestinal mucosa is known to occur in this entity. This infiltration of cells damages the mucosa due to the liberation of proteases, oxidation radicals and cytokines, among others. Apheresis techniques such as leukocyte apheresis may be used among the different therapeutic options such as steroids, sulfasalazine, 5-aminosalicylic, tacrolimus, azathioprine, cyclosporine, mycophenolate and biological agents.
