B-Cell function was evaluated in a group of 43 patients with factor VIII
or factor IX deficiency. Thirty had been treated primarily with
cryoprecipitate and 13 with concentrates of factor VIII or IX. Serum
immunoglobulin G levels were found to be diffusely elevated; however,
the absolute number of mature B cells in peripheral blood was normal.
B-Cell function as measured by testing mitogen-induced proliferation and
and immunoglobulin secretion by plaque-forming cells (PFC) in vitro was
reduced. Coculture experiments suggested that these abnormal B-cell
responses might be secondary to increased suppressor T-cell activity,
which was found more frequently in patients seropositive for antibody to
lymphadenopathy-associated virus. Both seronegative and seropositive
patients had reduced responses in the proliferative and PFC assays, but
the lowest PFC responses occurred in the seropositive group.
