  • Title: CD19+ in intestinal mucosa predict the response to infliximab in Crohn's disease.
    Author: Ferkolj I, Ihan A, Markovic S.
    Journal: Hepatogastroenterology; 2005; 52(64):1128-33. PubMed ID: 16001645.
    Abstract:
    BACKGROUND/AIMS: Infliximab is an effective treatment for Crohn's disease, yet about 30% of patients have a weak or no response. The aim of the study was to determine if the likelihood of a patient achieving complete remission 3 months after treatment with infliximab can be predicted from immunological parameters measured in peripheral blood and inflamed intestinal mucosa before the treatment. METHODOLOGY: 25 patients with Crohn's disease resistant to conventional therapy underwent treatment with infliximab. Samples of peripheral blood and inflamed intestinal mucosa were analyzed by flow-cytometry before infliximab administration. The clinical response was evaluated after 3 months. RESULTS: At 3 months post-treatment, 11 (44%) patients were in complete remission, while 14 (56%) had no remission. Logistic regression analysis revealed that 50% of patients having 2.29% of CD19+ cells in inflamed intestinal mucosa may be expected to achieve complete remission. If the proportion of CD19+ cells in the inflamed mucosa is 5%, the probability of the patient achieving complete remission following treatment rises to 85%. CONCLUSIONS: This is the first study which found that a high percentage of CD19+ cells in the inflamed intestinal mucosa of a patient with Crohn's disease may predict long remission after infliximnab therapy.
