【摘要】 目的 探讨影响糖皮质激素治疗特发性血小板减少性紫癜疗效的主要因素。 方法 回顾分析2008年1月-2010年7月173例特发性血小板减少性紫癜患者的临床资料，采用χ2检验及Logistic回归分析影响糖皮质激素疗效的相关临床因素。 结果 单因素χ2检验分析显示性别、骨髓巨核细胞计数水平、骨髓产板巨核细胞比例、乙型肝炎表面抗原（HBsAg）、血清免疫球蛋白水平对糖皮质激素疗效的影响有统计学意义（P lt;0.05）。脾脏长大、抗核抗体（ANA）阳性、补体C3水平降低与糖皮质激素疗效无关。多因素Logistic回归分析显示性别、HBsAg是影响糖皮质激素疗效的相关因素。 结论 男性、骨髓巨核细胞计数增多、产板巨比例降低者对糖皮质激素治疗反应较好。女性、血清免疫球蛋白水平异常、骨髓巨核细胞不增多者及HBsAg阳性的患者对糖皮质激素治疗反应相对较差。性别、HBsAg是影响糖皮质激素疗效的主要因素。
【Abstract】 Objective To discuss the influencing factors associated with the efficacy of glucocorticoid for idiopathic thrombocytopenic purpura. Methods We retrospectively analyzed the clinical data of 173 patients with idiopathic thrombocytopenic purpura who accepted their first treatment in West China Hospital between January 2008 and July 2010. The affecting factors on the efficacy of the treatment were analyzed by means of Chi-square test and binary logistic regression analysis. Results The results of Chi-square test showed that gender, bone marrow megakaryocyte count, the percentage of platelet-producing megakaryocytes, HBsAg, and the level of serum immunoglobulin could have a significant influence on the outcome of glucocorticoid treatment (P lt;0.05), while splenomegaly, positive ANA and decreasing of the level of complement C3 were not correlated with the outcome of glucocorticoid treatment. The results of multivariate logistic regression analysis showed that gender and HBsAg were correlated with the glucocorticoid treatment for patients with idiopathic thrombocytopenic purpura. Conclusion Male patients, patients with increasing bone marrow megakaryocytes and patients with decreasing percentage of platelet-producing megakaryocytes have better responses to glucocorticoid, while female patients, patients with abnormal serum immunoglobulin level and patients with non-increasing number of bone marrow megakaryocytes have poor responses toward glucocorticoid treatment. Gender and HBsAg are the main influencing factors for the response to glucocorticoid.
