Scarce data are available in Europe on the cost of treatment for ulcerative colitis (UC).To assess the cost of illness of moderate-to-severe UC in two scenarios: traditional treatment versus alternative treatment incorporating granulocyte, monocyte adsorption - apheresis (GMA-Apheresis; Adacolumn). To determine the relative cost-effectiveness of both options in steroid-dependent patients.One-year cost-of-illness and cost-effectiveness analysis from the third-payer perspective using a decision tree model was carried out. Probabilities of each event were derived from the literature and an expert panel. Direct medical costs were obtained from official sources (euro2004). Effectiveness was measured by the proportion of patients achieving clinical remission.The average annual cost per patient treated with traditional treatment was estimated to be euro6740; with GMA-Apheresis, the cost was estimated to be euro6959. In steroid-dependent patients, the average annual cost was euro6059 and euro11,436, respectively. The proportion of patients achieving clinical remission with GMA-Apheresis was 22.5% higher. As second- and third-line therapy, a new course of corticosteroids and surgery was avoided in 18.5 and 4% of patients, respectively.Incorporating GMA-Apheresis (Adacolumn) in the therapeutic management of moderate-to-severe UC patients is cost-effective and implies savings related to the reduction of adverse effects derived from corticosteroid use and to the decreased number of surgical interventions.
