[The association of a myeloma and Paget's disease (author's transl)].

The coexistence of a myeloma and Paget's disease in the same patient is only rarely reported in the published literature. The frequency of such an association was studied when reviewing 3 cases observed by the authors: an IgG myeloma discovered following a spasmodic paraplegia in a patient with Paget's disease; a patient who was found to have a myeloma, a polynuclear neutrophil leukemia, and Paget's disease; and an IgG myeloma in a patient with probable localized Paget's disease. The incidence of the association myeloma-Paget's disease is much lower than that of sarcomatous degeneration. It should be determined precisely, however, as our future conception of the reciprocal relationship between the two diseases is greatly dependent on this information. Furthermore, the very few cases reported, and their lack of homogenicity, are the reasons why most authors feel that the association of myeloma and Paget's disease as pure coincidence. Many new cases, however, have been recently reported. The problem of the significance of the association of Paget's disease and macroglobulinemia or other monoclonal gammapathies has still to be solved.

Histamine release reaction of basophils in chronic granulocytic leukaemia. Induction by heterologous anti-immunoglobulin E, concanavaline A, and phytohaemagglutinin; effect of heavy water.

Basophils possess membrane bound IgE molecules, and immunological activation leads to a secretory process with cell degranulation and histamine release. Heterologous anti IgE, concanavaline A, and phytohaemagglutinin are potent non-cytotoxic releasing agents. They operate by a mechanism similar to that of immunological activation. Heavy water is not a histamine releasing inducer but it increases histamine release of the cells. We studied the histamine release reaction of leukaemic basophils in 10 patients and found a physiological response such as that previously reported with normal human basophils.
