Abstract :
Coincidence of autoimmune diseases such as immune thrombocytopenic purpura (ITP)
with immunodeficiencies has been reported previously in patients who suffered from
primary antibody deficiency (PAD). But there is no original study on immunological profiles
of ITP patients to find out their probable immune deficiency.
In this case-control study, ITP patients’ humoral immunity was investigated for diagnosis
of PAD in comparison with normal population. To evaluate the humoral immune system
against polysaccharide antigens, patients’ serum immunoglobulin levels were measured and a
23-valent pneumococcal capsular polysaccharide vaccine (PPV23) was administrated to
evaluate the antibody response to vaccination.
In this study, 14 out of 36 patients (39%) were diagnosed with antibody mediated
immune deficiency including 2 patients (5.5%) with immunoglobulin class deficiency and 4
(11%) with IgG subclass deficiency. The remaining patients suffered from specific antibody
deficiency. The most frequent deficiency in ITP patients was specific antibody deficiency.
Therefore, immunological survey on ITP patients may be important especially for those
who have undergone splenectomy.
