[Problems posed by the preparation of specific anti-cytomegalovirus immunoglobulins].
The authors describe the preparation of a first batch of intravenous cytomegalovirus (CMV) immune globulin at the Nancy Regional blood transfusion centre. Immune plasmas were selected from 3 640 healthy volunteer blood donors on the basis of CF antibody titers to CMV (Kolmer's method modified) of, at least, 1:8; plasmas from approximately 10% of the donors were therefore selected. The 68 liters of pooled immune plasma had à CF antibody titer of 1:16 (CMV antibody titers of 1: 10 000 and 1: 640 when tested in the ELISA assay and passive hemagglutination assay respectively). Intravenous immune globulin was produced from pooled plasma by Cohn fractionation and treatment with pepsin at pH 4; 4.8 liters of immune globulin were prepared and divided in 96 doses of 50 ml each. The final product was found to have a CMV antibody titer of 1: 32 (CF) 1: 50 000 (ELISA) or 1: 2 560 (passive hemagglutination). Recent reports on the preparation of CMV immune globulin are briefly reviewed.
