幽门螺旋杆菌(Helicobacter pylori,HP)感染一直是医疗界关注的热点、难点问题之一。HP感染率达世界人口的一半左右,可导致急慢性胃炎、消化性溃疡、胃癌、胃黏膜相关组织淋巴瘤等多种胃肠道疾病。国内外相关研究[1-2]发现,HP感染还与糖尿病、心血管疾病、脂肪肝、肝硬化、特发性血小板减少性紫癜、慢性荨麻疹、胆囊结石、缺铁性贫血、脑梗死、妊娠相关疾病等多种躯体疾病相关。HP感染已被世界卫生组织认定为Ⅰ级或明确的人类致癌因子,而根除HP是防治上述疾病的重要环节[3]。但目前HP根除成功率仍较低,HP根除失败是临床常见且具有挑战性的问题。我们对HP感染根除治疗失败病人的相关资料和指标进行调查分析,探讨其根除失败的常见原因,以期为临床提供参考。现作报道。

结果显示,居住地、文化程度、有家庭成员感染、CagA阳性、口腔HP感染、治疗情况、不规则服药、耐药、未全程督导在失败组和治愈组之间差异均有统计学意义(P < 0.05~P < 0.01),而性别、年龄、病菌分级、有无合并症、吸烟、饮酒在2组之间差异均无统计学意义(P>0.05)(见表 1)。

摘要:
目的分析根除幽门螺旋杆菌治疗失败的原因及其临床影响因素。 方法选取幽门螺旋杆菌感染病人257例,按照幽门螺旋杆菌根除结果分为失败组77例和治愈组180例,收集病人一般资料及临床相关指标,分析根除幽门螺旋杆菌治疗失败的原因。 结果幽门螺旋杆菌根除失败率为29.96%(77/257)。单因素分析显示,居住地、文化程度、有家庭成员感染、CagA阳性、口腔HP感染、治疗情况、不规则服药、耐药、未全程督导在失败组和治愈组之间差异均有统计学意义(P < 0.05~P < 0.01)。logistic回归分析显示,文化程度和不规则服药均为根除失败的独立影响因素(P < 0.01和P < 0.05)。 结论文化程度、不规则服药等多种因素影响根除幽门螺旋杆菌治疗结果,临床应根据相关影响因素及早干预。 Abstract:ObjectiveTo analyze the reason of the eradication failure of Helicobacter pylori(HP), and its clinical influencing factors. MethodsTwo hundred and fifty-seven patients with HP infection were divided into the failure group(77 cases) and cure group(180 cases) according to the eradicating result.The general information and clinical indicators in two groups were collected to analyze the failure causes of eradicating HP. ResultsThe failure rate of eradicating HP was 29.96%(77/227).The results of univariate analysis showed that the differences of the residence, education level, infection of family members, CagA positive, oral HP infection, treatment status, irregular medication, drug resistance and incomplete supervision between two groups were statistically significant(P < 0.05 to P < 0.01).The results of logistic regression analysis showed that the education level and irregular medication were the independent influencing factors of eradication failure(P < 0.01 and P < 0.05). ConclusionsA variety of factors, such as cultural level and irregular medication, can affect the eradication results of HP, and the clinical intervention should be conducted as early as possible according to relevant influencing factors. -
