[Unusual clinical aspects of 3 cases of primary humoral immunodeficiency].

The clinical behaviour of three patients with primary antibody deficiencies was studied. Two of three were affected by X-linked agammaglobulinemia and one by common variable hypogammaglobulinemia that, besides clinical features common to most of the immunodeficiencies, showed pre-existent physiopathologic conditions completely different from the features traditionally found in primary antibody deficiencies. Moreover, the development of some immunologic parameters (monoclonal antibody analysis, surface markers and electrophoretic mobility of lymphocytes) has been carefully checked in these patients after immunotherapy by intravenous infusion of immunoglobulins. The lymphocyte electrophoretic mobility underlines how peripheral blood lymphocytes, faster than those normally controlled before therapy, normalized their velocity after immunotherapy.
