Objective To systematically evaluate the effectiveness of platelet increasing capsule combined with hormone in treating idiopathic thrombocytopenic purpura (ITP). Methods Randomized controlled trials (RCTs) of ITP treated by platelet increasing capsule combined with hormone were electronically searched from PubMed (1966 to 2012), The Cochrane Library (CENTRAL, Issue 3, 2012), CBM (1978 to 2012), CNKI (1979 to 2012), WanFang Data (1998 to 2012), and VIP (1991 to 2012). References of included studies were also retrieved. The literature was independently screened according to exclusion and inclusion criteria by two researchers independently and meta-analysis was conducted using RevMan 5.1 software after data extraction and quality assessment. Results 10 RCTs were included involving 588 patients. The results meta-analysis showed that, the group which was treated by platelet increasing capsule combined with hormone was superior to the hormone alone group in the aspects of overall effectiveness rate (RR=1.18, 95%CI 1.06 to 1.32, P=0.003), the significant effectiveness rate (RR=1.57, 95%CI 1.29 to 1.91, Plt;0.000 01), blood platelet count (MD=21.54, 95%CI 13.85 to 29.23, Plt;0.000 01), and the recurrence rate (RR=0.49, 95%CI 0.34 to 0.69, Plt;0.000 01) which was lower. Conclusion Current evidence has showed that platelet increasing capsule combined with hormone in treating ITP is better than hormone alone. However, more high quality RCTs are needed to verify the above conclusion in future.
【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（Plt;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 (Plt;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.
目的 探讨腹腔镜下脾切除术（LS）治疗特发性血小板减少性紫癜(ITP)的临床效果。方法 我院2003年1月至2008年8月期间行LS治疗ITP患者20例，将术前与术后1、2、7、14、30、90及180 d的血小板计数进行比较。结果 20例ITP患者均顺利完成LS，平均手术时间为156 min，术中出血平均50 ml，平均住院时间为9 d。完全停用药物14例； 4例患者术后需继续服用激素治疗，但激素用量较前明显减少； 无效2例。总有效率为90%。术后1、2、7、14、30、90及180 d的血小板数量分别为(251.6±91.4)×109/L、(312.6±90.1)×109/L、(343.2±103.7)×109/L、(300.0±98.2)×109/L、(175.6±42.6)×109/L、(151.8±42.1)×109/L及(207.0±53.4)×109/L,分别与术前〔(38.3±19.4)×109/L〕比较，经t检验，差异均有统计学意义（P＜0.001）。结论 LS治疗ITP是可行和安全的，手术效果满意。
ObjectiveTo systematically review the clinical effectiveness and safety of middle and low-dose gamma globulin for severe idiopathic thrombocytopenic purpurar (ITP). MethodsDatabases such as The Cochrane Library (Issue 2, 2013), PubMed, EMbase, CBM, CNKI and WanFang Data were searched to collect randomized controlled trials (RCTs) involving the effectiveness and safety of middle and low-dose gamma globulin for severe ITP from the date of their establishment to July 2013. Two reviewers independently screened studies according to the inclusion and exclusion criteria, extracted data and evaluated the methodological quality of included studies. Then meta-analysis was performed using RevMan 5.2 software. ResultsEleven RCTs involving 548 patients were included. The trial group (n=272) were treated with middle and low dose of gamma globulin, while the control group (n=276) were treated with high dose of gamma globulin. The results of meta-analyses showed that there were no significant differences between the two groups in the total effective rate (RR=0.95, 95%CI 0.87 to 1.04, P=0.30), overall response rate (RR=0.97, 95%CI 0.85 to 1.10, P=0.60) and excellence rate (RR=0.94, 95%CI 0.78 to 1.14, P=0.54). The outcomes of time effect such as the time of platelet starting to rise and haemostasis time between the two groups was similar without significant differences. However, the control group was superior to the trial group in the peak time of platelet. The results of meta-analysis for platelet count of different periods showed that no significant differences were found in platelet count of 3, 7, and 14 days after starting the treatment, so do the peak of platelet count. No severe side effects were reported by both groups. ConclusionMiddle and low-dose gamma globulin could achieve the similar effect with the high-dose gamma globulin in the treatment of ITP. However, more high-quality, large-scale, RCTs are required to validate these results.
Idiopathic thrombocytopenic purpura (ITP) is a common bloody disease with a high incidence in children, but its diagnostic method is exclusive diagnosis, and the existing detection techniques are mostly invasive, which may cause secondary injury to patients and also may increase the risk of disease. In order to make up for the lack of the detection method, this study made a preliminary exploration on the diagnosis of children's ITP from the perspective of infrared thermography. In this study, a total of 11 healthy children and 22 ITP children's frontal infrared thermal images were collected, and the pattern characteristic (PFD), average temperature (Troi) and maximum temperature (MAX) characteristics of 7 target areas were extracted. The weighted PFD parameters were correlated with the platelet count commonly used in clinical diagnosis, and the sensitivity and specificity of the weighted PFD parameters for children's ITP were calculated through the receiver operating characteristic curve (ROC). The final results showed that the difference of the weighted PFD parameters between healthy children and ITP children was statistically significant, and the parameters negatively correlated with platelet count. Under the ROC curve, the area under the curve (AUC) of this parameter is as high as 92.1%. Based on the research results of this paper, infrared thermography can clearly show the difference between ITP children and healthy children. It is hoped that the methods proposed in this paper can non-invasively and objectively describe the characteristics of ITP infrared thermal imaging of children, and provide a new ideas for ITP diagnosis.
