title: [A clinical analysis of 125 cases of immune thrombocytopenia].
abstract: This study was aimed to investigate the clinical features of patients with immune thrombocytopenia (ITP). The clinical data, laboratory results and therapeutic effects of 125 inpatients with ITP from January 2005 to May 2010 were retrospectively analyzed. The results showed that median age of 125 inpatients was 41, and the sex ratio of male to female was 1:1.78. The average pre-treatment platelet count was (28.59 ± 23.05) × 10(9)/L. 69.1% patients (67/97) suffered from rheumatoid or immune abnormalities. The carrier rate of hepatitis B virus and parvovirus B19 were 37.3% (22/59) and 44.8% (26/58) respectively. CD3(+)T cells in chronic patients was (62.7% ± 14.11%), while that in acute patients was (55.44% ± 14.31%). The rate of CD19(+)B cells in chronic patients was (12.83% ± 6.96%), that was (19.47% ± 6.93%) in acute patients. 91 patients were subjected to the examination for bone marrow mononuclear cell membrane antibody, with 54.9% (50/91) cases negative and with 45.1% (41/91) cases positive. 63.0% (17/27) acute patients were positive, while that was 37.5% (24/64) in chronic patients. Therapy of hormone combined with cyclosporine showed efficiency of 81.7% (49/60), the response of some refractory patients to RCP chemotherapy or azathiopurine cytotoxic drugs showed efficiency of 57.14% (4/7) and 40.0% (2/5) respectively. It is concluded that patients with ITP always accompany with virus infection or rheumatism abnormalities. Acute patients always accompany with hyperfunctioning of humoral immune, while the chronic ones were with hyperfunctioning of the cellular immune. Patients with positive bone marrow mononuclear cell membrane antibody are more likely to be acute. In order to obtain a better effect, the treatment strategies should be based on different pathogenesis to choose different drugs or different combinations of medicine.
