Value of adhesion molecules for evaluating the efficiency of therapy for ulcerative colitis and Crohn's disease

Abstract

AIM: To define the value of adhesion molecules (sVCAM-1 integrin, P-selectin, E-selectin, and L-selectin) for the prediction and evaluation of the efficiency of treatment in patients with ulcerative colitis (UC) and Crohn's disease/MATERIAL AND METHODS: Twenty-six patients with UC and 14 patients with CD were examined. Of them, 16 patients took infliximab (INF) in a dose of 5 mg/kg of body weight according to the standard scheme; 14 patients received cultured mesenchymal stem stromal cells (MSSCs) in a quantity of 150·108 cells, and 10 had azathioprine (AZA) 2 mg/kg and glucocorticosteroids (GCS) 1 mg/kg of body weight. Enzyme immunoassay was used to determine the serum concentration of the adhesion molecules (L-selectin, E-selectin, P-selectin, and sVCAM-1 integrin) before and 2 months after treatment/RESULTS: The signs of bowel inflammatory disease activity and the elevated levels of adhesion molecules whose synthesis did not occur under normal conditions remained in the patients receiving GCS and AZA. INF treatment caused a decrease in P-selectin, E-selectin, and sVCAM-1 levels to 8.9±1.0, 5.5±1.7, and 9.5±4.4 ng/ml, respectively (p
