  • SELECTIVE POLYSACCHARIDE ANTIBODY DEFICIENCY IN FAMILIAL DIGEORGE SYNDROME ANNALS OF ALLERGY Schubert, M. S., Moss, R. B. 1992; 69 (3): 231-238

    Abstract:

    A family including three children with DiGeorge syndrome is described. One child died in the neonatal period from cardiac anomalies accompanying complete DiGeorge syndrome. The two surviving siblings shared a common set of pharyngeal pouch anomalies and immunodeficiency consistent with partial DiGeorge syndrome, and other morphologic anomalies characteristic of the velocardiofacial syndrome with which familial DiGeorge syndrome is associated (reviewed in reference 1). Both had normal karyotypes. Both presented with recurrent otitis media and sinopulmonary infections, CD4+ T cell lymphopenia, and defective DCH skin test responses to recall T cell antigens. Both had low serum IgM levels and IgG4 levels at the lower limits of normal. Immunization with bacterial polysaccharides resulted in impaired IgG antibody responses to the same set of antigens (H. influenzae polyribophosphate and S. pneumoniae capsular serotypes 9N and 14), while responses to protein antigens were intact. Both siblings were treated successfully with intravenous gamma globulin. The pattern of selective antibody deficiency in these patients with familial DiGeorge syndrome suggests a heritable lesion in certain regulatory antipolysaccharide CD4+ T cell subpopulations.
