Monoclonal immunophenotyping of leukemia cells of the bone marrow was carried out by the method of rapid immune alkaline phosphatase (RIAP) in 30 patients with acute lymphoblastic leukemia (ALL) aged 6 months-14 years. The authors used a panel of monoclonal antibodies (MCA) produced by Leu (Belgium) and DAKO (Denmark) directed to antigens of differentiation clusters: Tdt, HLA-DR, CD: 10, 19, 20, 22, 7, 8, 2, 5, 13, 33, 14. The results indicate diversity of compositions of differentiating antigens on leukemia cells of the dominant population and a different degree of leukemic cell pool heterogenicity. RIAP advantages over flow cytometry in immunotyping of ALL cells are shown. Arguments are provided in favor of introduction of broader MCA panel.
The authors investigated cellular and humoral immunity in 53 children over 3 years of age suffering from acute lymphoblastic leukemia. The children had remission lasting from 6 to 120 months and were followed up for 7-14 years after the diagnosis was made. The treatment was performed according to programs of polychemotherapy practiced in 1981-1988. In November of 1995 42 children were alive, 15 had the disease for 10 years. Lymphocytopenia (absolute number of T-cells and B-cells fell 3-5 and 2-3-fold, respectively) was reported in all the examinees both in early remission and later (6-12, 24-60, 60 and more months since the disease onset). In early remission there was a significant reduction in the serum IgG, IgA and IgM. In children with ALL lethal outcome serum IgM and absolute number of E-RFCa dropped in early remission more significantly indicating deep drug-induced depression of lymphocytopoiesis. After 5 years of treatment the pool of peripheral T-lymphocytes and T/B lymphocyte proportion changed for the best, though their absolute number was subnormal. Serum IgG, IgA and circulating immune complexes were 1.3-1.5 times higher than normal which may be explained by gastrointestinal pathology and food allergy in the majority of children treated.
