Methods: Forty-one children of RITP were randomized into the treated group and the control group. The 21 patients in the treated group were orally given 2 to 3 DZC capsules each time, thrice a day and the 20 in the control group were given 3 mg/kg CsA per day, with 3 months as one therapeutic course. The therapeutic efficacy, platelet count and adverse reaction in the two groups were compared at the end of the course. Results: (1) In the treated group, 1 (4.8%) patient was evaluated as cured, 3 (14.3%) as markedly effective, 5 (23.8%) as effective, 5 (23.8%) as improved, 7 (33.3%) as ineffective, with the total effective rate being 66.7%; while in the control group, the corresponding numbers were 0. 2 (10.0%), 2 (10.0%), 3 (15.0%), 13 (65.0%) and 35.0%, respectively, showing statistical significance in difference between the total effective rates of the two groups ( Х^2=4.11, P=0.0426). (2) As compared with the baseline, the platelet count increased in both groups after 2 months' treatment (P〈0.05). After 3 months' treatment, the platelet count was higher in the treated group than in the control group (P〈0.05). (3) The improvement of hemorrhage in the treated group after 8 weeks' treatment was better than that in the control group (P〈0.05). (4) No apparent adverse reaction was observed in the treated group, while in the control group, hirsutism was shown in 15 cases; gingival hyperplasia in 10; digestive reaction in 5, liver function impairment in 5, hypertension in 2 and renal impairment in 2. Conclusion: The therapeutic efficacy of DZC is better than that of CsA, and DZC shows good compliance but brings no obvious adverse reaction.展开更多

文摘目的探讨加用全反式维甲酸ATRA对难治性特发性血小板减少性紫癜(RITP)的疗效及对患者外周血调节性T(CD 4^+CD 25^(high)T)细胞表达和辅助性T(Th)细胞因子的影响。方法应用流式细胞术测定28例RITP患者ATRA治疗前后及17例正常人外周血CD 4^+ CD 25^(high)T细胞的表达;ELISA法测定血清中转化生长因子β1(TGF-β1)、白介素(IL)-10、IL-4、IL-2、干扰素γ(IFN-γ)。结果ATRA对RITP的总有效率为53.6%,有效组治疗后患者外周血血小板计数达109.1±30.1×10~9/L,较治疗前明显升高(P<0.01);治疗有效组经ATRA治疗后CD 4^+ CD 25^(high)T细胞阳性率及血清TGF-β1与IFN-γ水平高于治疗前(P<0.05);IL-4则明显低于治疗前(P<0.05);IL-2和IL-10治疗前后未见异常。结论ATRA对半数以上RITP患者有效,可能是通过提高调节性T细胞的表达,促进了RITP患者免疫紊乱向生理性平衡恢复。
