Selective antipolysaccharide antibody deficiency associated with peripheral blood CD5+ B-cell predominance.

Background: Primary humoral deficiencies vary from complete absence of B cells and/or serum immunoglobulin to lacunar deficits involving specific antibody responses to polysaccharides.

Objectives: We compared the B-cell CD5 expression in patients with selective antipolysaccharide antibody deficiencies (SPADs), common variable immunodeficiency (CVID), and IgG subclass deficiency and in normal control subjects.

Methods: Five patient populations were evaluated: (1) patients with severe SPAD (no protective serologic postvaccine response to any of 12 polysaccharide antigens tested); (2) patients with intermediate SPAD (diminished response to polysaccharide antigens and adequate response to 1 to 3 of 12 serotypes tested); (3) patients with IgG subclass deficiency; (4) patients with CVID; and (5) age-matched control subjects.
