We have studied the primary in vitro antibody response toward a hapten in cultures of peripheral blood lymphocytes from twenty-two patients suffering from regular rheumatoid arthritis (RA). These patients were not receiving immunosuppressive drugs or corticosteroids and had not taken Aspirin or non-steroidal anti-inflammatory agents for at least 72 hr. The(More)
The in vitro antibody response of peripheral blood lymphocytes (PBL) from 19 patients with untreated systemic lupus erythematosus (SLE) was compared with that of 20 control patients and 44 normal subjects. Trinitrophenyl polyacrylamide beads (TNP-PAA) were used to induce IgM anti-TNP plaque-forming cells. SLE patients displayed a markedly depressed, and in(More)
The effect of bone marrow plasma cell morphology at diagnosis on survival time was evaluated in 66 patients with multiple myeloma. According to the morphologic classification multiple myeloma was categorized as plasmacytic, plasmacytic/plasmablastic, or plasmablastic. The plasmablastic myeloma had an estimated median survival of 9 months compared with 42(More)
