幽门螺旋杆菌在特发性血小板减少性紫癜发病中临床意义研究

为了探讨特发性血小板减少性紫癜（ITP）患者幽门螺旋杆菌（HP）感染的发生率及糖皮质激素联合抗HP治疗ITP的疗效，100例HP阳性ITP患者随机分为联合治疗组（根除HP及糖皮质激素治疗，n=35）、单用糖皮质激素组（n=35）和单纯抗HP组（n=30），100名健康体检者作为对照组。。结果表明：ITP组HP感染率为70％，而对照组HP感染率为56％，2组差异有显著性（p〈0．05）。联合治疗组给予根除HP及糖皮质激素治疗后，31例HP得到根除，其中23例血小板水平恢复正常，8例较治疗前升高，血小板均数为（165±225）×10^9／L，与治疗前相比有统计学意义（p〈0．01），总有效率89％，1年内复发率8％。糖皮质激素组中有2例HP自然转阴，血小板水平恢复正常，其余33例HP仍然阳性的患者中23例血小板水平未恢复正常，10例恢复正常，血小板均数为（78±26）×10^9／L，总有效率68％，1年内复发率37％。单纯抗HP组中25例肿得到根除，其中9例血小板水平恢复正常，9例较治疗前升高，血小板均数为（135±174）×10^9／L，与治疗前相比有统计学意义（p〈0．01），总有效率60％，1年内总复发率为33％。结论：ITP患者有高HP感染率，根除HP是合并HP感染的ITP患者行之有效的治疗方法，并可作为一线治疗。

Clinical Significance of Helicobacter Pylori in Pathogenesis of Idiopathic Thrombocytopenic Purpura

This study was purposed to investigate the infection incidence of Helicobacter pylori (HP) in patients with idiopatic thrombocytopenic purpura (ITP) and curative efficacy of glucocorticoids combined with anti-helicobacter. 100 ITP patients with positive HP were divided randomly into 3 groups: glucocorticoid group (treatment with glucocorticoids, n = 35), anti-HP treatment group (HP eradication, n = 30) and combined treatment group (glucocorticoid combined with HP eradication, n = 35). 100 healthy individuals were selected as control. The results showed that HP infection rate in ITP group was 70%, while HP infection rate in control group (persons received physical examination) was 56%, there was significant difference between two groups (p < 0.05). The HP of 31 cases in combined treatment group was eradicated that the platelet count in 23 out of 31 cases recovered to mormal, and in 8 cases was higher than that before treatment, which mean count was (165 +/- 225) x 10(9)/L, this value had statistical significance as compared with that before treatment (p < 0.01). Total efficiency in this group reached to 89%, and relapse rate within 1 year was 8%. The HP infection of 2 cases in glucocorticoid group had been turned to negative naturally, and platelet count recovered to normal, while HP infection in remained 33 cases was still positive. The platelet count in 23 out of 33 cases of that group was not back to normal, but back to normal in 10 cases. The platelat mean count in that group was (78 +/- 26) x 10(9)/L with total efficiency rate of 68% and relapse rate within 1 year was 37%. In the anti-HP treatment group, HP infection in 25 cases was eradicated and platelet count in 9 out of 25 cases recovered to normal, that platelet count in 9 cases was higher than that before treatment, platelet mean count was (135 +/- 174) x 10(9)/L), there was significant difference (p < 0.01), as compared with value before treatment. Total efficiency rate in this group reached to 60%, and relapse rate within 1 year was 33%. It is concluded that the patients with ITP have higher HP infection incidence, and the eradication of HP is effective therapy for the ITP patients with HP infection, which can be used as initial treatment.
