Susceptibility to infections in children with selective IgA- and IgA-IgG subclass deficiency. 1986

A Morell, and E Muehlheim, and U Schaad, and F Skvaril, and E Rossi

This study included 36 children with IgA-deficiency, increased susceptibility to infections and/or other disorders. Recurrent, usually bacterial infections were noticed in 23 out of 26 patients (88%) with complete and in 7 out of 10 patients (70%) with partial IgA-deficiency. All patients with severe infections had complete IgA-deficiency. Complete IgA-deficiency was also present in the six children who had autoimmune disorders associated with recurrent infections. In 22 out of the 36 patients studied the serum could be analysed for concomitant IgG subclass deficiencies: one patient had marked decrease of IgG2. In a second patient IgG4 was not detectable. Two patients had combined IgG2-IgG4-deficiency. In a girl with severe acute and chronic infections and relapsing idiopathic thrombocytopenic purpura, IgA-IgG2-IgG4-deficiency was found to be the prodromal stage of common variable immunodeficiency with panhypogammaglobulinaemia.
