Résumé
Immune complexes, lymphopenia, and lymphocytotoxic antibodies were detected in two patients with hypergammaglobulinemic purpura of Waldenstrom. These abnormalities were further characterized in one patient. Ultracentrifugation analysis of this patient's serum showed an intermediate peak likely representing medium sized immune complexes. Circulating IgG-containing immune complexes (2-ME resistant Clq binding material) and IgM rheumatoid factor (2-ME sensitive) were also detected. A sequential study of cold reactive IgM lymphocytotoxic antibodies revealed a significant inverse correlation between antibody levels and peripheral lymphocyte counts. The possible implications of these findings in the pathogenesis of hypergammaglobulinemic purpura are discussed.
