Objective To investigate the immune status characteristics of primary ITP patients with abnor-mal auto-antibodies. Methods A total of 110 patients were enrolled in our study,who were admitted in Fu-Xing Hospital affiliated to Capital Medical University from January 2001 to July 2015.According to whether the patients have autoimmune diseases and the presence of auto-antibodies,we divided the patients into 3 groups,including the primary ITP with abnormal auto-antibodies(PITP-ANA)group,the primary ITP(PITP)group and the second-ary ITP(SITP)group.We compared the T-cell subsets,regulatory T cells,B lymphocytes,changes of immunoglob-ulin and bone marrow biopsy and cytology of patients among the three groups,retrospectively. Results The per-centage of CD3+T cells(61.72 ± 10.60)% in PITP-ANA group was lower than that in PITP group(69.57 ± 11.99)%. The percentage of CD8+T lymphocyte(24.00 ± 7.67)% was significantly lower than that of PITP group (30.59 ± 11.08)%(P<0.05).The proportion of Treg in PITP group,PITP-ANA group and SITP group were(6.12 ± 1.41)%,(7.50 ± 2.76)% and(8.49 ± 2.47)%,respectively,with statistically significant differences.The ra-tio of CD19+T cell in PITP-ANA group(25.75 ± 9.98)%was significantly higher than that in PITP group(16.16 ± 8.19)%(P < 0.01). The concentration of IgG、IgA、κ light chain and λ light chain in PITP group,PITP-ANA group and SITP group showed an upward trend and the highest level was in the SITP group,with statistically signifi-cant differences among the three groups. A variety of abnormal auto-antibodies could be found in both PITP-ANA group and SITP group. Conclusions We consider that the immune function abnormity of patients in PITP-ANA group were worse than that in PITP group,because the concentration of immunoglobulin,the percentage of B lym-phocyte and Treg ratio are higher in than those in PITP group.
