| Abstract: | Abstract: Leukocytapheresis (LCAP) is widely used for the treatment of immunological diseases. We studied a new treatment of LCAP using a nonwoven polyester filter. In a basic study, 30–70% of the lymphocytes were adsorbed. Also, 30–68% of the lymphocyte subsets were removed. This method was applied to 2 patients with corti-costeroid-resistant active ulerative colitis. Erosion, edema, bleeding, ulcer formation, and stenosis of the colon were almost completely repaired after 6 LCAP treatments. LCAP using a nonwoven polyester filter will be a very useful treatment for immunological diseases and extracorporeal immunomodulation. |
