Abstract:
The study was aimed to explore the relationship between infection of Helicobacter Pylorus (H. Pylorus) and etiology of idiopathic thrombocytopenic purpura (ITP) and evaluate whether H. Pylorus eradication can increase platelet count in patients with ITP. The data-bases of cqvip, Wanfang, TsingHua TongFang, CNKI and PubMed were searched, inclusion and exclusion criteria and heterogeneity test were determined. The studies of H. Pylorus infection and ITP were investigated with fixed effect mode Meta-analysis. Relationship between H. Pylorus infection and etiology of ITP, H. Pylorus eradication and curative effect of ITP were comprehensively and quantitatively evaluated. OR > 1 indicated that factor of exposure was the risk factor of disease; OR < 1 suggested that factor of exposure was the protective factor of disease; OR = 1 revealed that there were no correlation between factor of exposure and diseases. 95%CI was the confidence interval of total OR. The results showed that a total of 211 cases and 210 controls from 5 studies was included to evaluate the exposure of H. Pylorus between ITP patients and controls, the pooled OR was 1.73 (95%CI = 1.12 - 2.67); a total of 458 cases and 305 controls from 13 studies was included to evaluate the relationship between H. Pylorus eradication and curative effect of ITP, the pooled OR was 6.53 (95%CI = 4.44 - 9.61). It is concluded that H. Pylorus infection plays a role in the etiology of ITP. Eradication of H. Pylorus increases platelet count in patients with ITP. H. Pylorus eradication can be used as the first line measure to treat H. Pylorus-positive ITP.
