Immunoreconstitution after human bone marrow transplantation.
Immunologic reconstitution was studied in 24 patients who underwent bone marrow transplantation, 17 allogenic and 7 autologous. The GVHD prophylaxis consisted of methotrexate and prednisone. The complete immune evaluation was to be carried out prior to transplantation at 1, 2, 3, 6, 9, 12 months after BMT and subsequently every 6 months up to 4 years. The investigated immunological parameters included total lymphocyte count, B-lymphocytes, T3-, T4-, T8-lymphocytes, T4/T8 ratio, natural killer cell activity, ADCC, lymphocyte blastogenic response and serum-IgG, -IgA, -IgM. Absolute lymphocyte count, B-lymphocytes, T3-lymphocytes recovered to normal levels after 6 months. T4-lymphocytes decreased significantly during the first 180 days posttransplant. T8-lymphocytes increased after 6 months to values higher than normal and the T4/T8 ratio decreased significantly and continued below 0.8 for 48 months. Patients without and with GVHD had low lymphocyte response to PHA and Con A for the first 6 months.
