title: [The role of leukemic cell apoptosis and adhesive molecule sICAM-1 in the clinical evolution of acute lymphoblastic leukemia in children].
abstract: Total number of 160 children with ALL, 98 boys and 62 girls, aged from 0.5 to 18 years was included in the study. Apoptotic cells death acc. to annexin V and ICAM-1 levels in serum and cell culture supernatants according to conventional antibody sandwich ELISA Genzyme assay were studied. Blood samples were drawn from children at different stages of their disease: at the time of diagnosis, during intensive therapy (induction, consolidation), during maintenance therapy and after completing the treatment. Thirty seven healthy children served as the control group. ICAM-1 before therapy was higher than that obtained in control group of healthy children (5.619 v 2.53 g/l). ICAM-1 decrease (3.228) after starting of chemotherapy of ALL was noticed. It was found that in children with ALL during the whole period of therapy the ICAM-1 serum levels were significantly lower than that observed in the control group of healthy children (p < 0.005). After cessation of the therapy ICAM-1 grew up (6.27 g/l). Therapeutics that modulate the regulation of apoptosis and/or expression of sICAM and cytokines production provide a new opportunity for the treatment of childhood ALL.
