Helicobacter Pylori Infection in Children and its Correlation with Iron Deficiency Anemia
-
摘要:
目的 了解大理白族自治州人民医院门诊528例上腹痛儿童幽门螺杆菌(H.pylori)感染情况并研究感染与缺铁性贫血(iron deficiency anemia,IDA)的相关性;为儿童H.pylori感染和IDA的诊断和治疗提供一定的循证医学证据。 方法 (1)选取2019年1月至2020年12月在大理白族自治州人民医院门诊因上腹痛进行13C-尿素呼气试验(13C-urea breath test,13C-UBT)的3~13岁患儿共计528例,对被检测小儿的性别、民族进行问卷调查分析;(2)其中H.pylori阳性患儿共119例作为观察组,H.pylori阴性患儿共409例作为对照组。 所有患儿同时进行血红蛋白(hemoglobin ,Hb)、平均红细胞体积(mean red blood cell volume,MCV)、血清铁(serum iron,SI)、总铁结合力(total iron binding capacity,TIBC)、铁蛋白(serum ferritin,SF)检测,观察IDA的发生情况,并分析H.pylori感染与IDA的相关性。 结果 (1)528名受检儿童H.pylori总感染率为22.53%,其中男女儿童H.pylori感染阳性率分别22.88%和22.22%,男女儿童H.pylori感染阳性率差异无统计学意义(χ2 = 0.08,P > 0.05);受检儿童中汉族、白族、藏族、其他少数民族儿童H.pylori感染阳性率分别为17.95%、20.69%、64.29%、26.92%。H.pylori感染阳性率差异有统计学意义(χ2 = 273.659,P < 0.01);(2)观察组Hb、MCV、SI、SF水平均显著低于对照组,且TIBC水平明显高于对照组,差异有统计学意义(P < 0.05)。 结论 (1)H.pylori感染率与性别无关,并且存在明显民族聚集现象;(2)H.pylori感染与儿童IDA发生有一定的相关性,H.pylori感染可能是IDA的一个致病因素。故临床治疗IDA时应常规进行H.pylori监测,必要时进行抗H.pylori治疗,以获得更好的临床治疗效果。 Abstract:Objectives To investigate the infection of H.pylori in 528 children with epigastric pain in Dali Bai Autonomous Prefecture People’s Hospital, to study the correlation between infection and iron deficiency anemia (IDA) and to provide evidence for the diagnosis and treatment of H.pylori infection and IDA in children. Method A total of 528 children aged 3 to 13 who received 13C-UBT due to upper abdominal pain in the outpatient department of Dali Bai Autonomous Prefecture People’ s Hospital from January 2019 to December 2020 were selected, and the gender and ethnicity of the detected children were analyzed by questionnaire. There were 119 H.pylori positive children listed as the observation group, and 409 H.pylori negative children listed as the control group. Hemoglobin (Hb), mean red blood cell Volume (MCV), serum iron (SI) , total iron binding capacity (TIBC) and serum ferritin (SF) were tested to determine the occurrence of IDA, and the correlation between H.pylori infection and IDA was analyzed. Results The total infection rate of H.pylori in 528 children was 22.53%, and the positive rates of H.pylori in male and female children were 22.88% and 22.22%, respectively. There was no significant difference in the positive rate of H.pylori in male and female children (χ2 = 0.08, P > 0.05). The positive rates of H.pylori infection in Han, Bai, Tibetan and other minority children were 17.95%, 20.69%, 64.29% and 26.92%, respectively. The positive rate of H.pylori infection was significantly different (χ2 = 273.659, P < 0.01). The levels of Hb, MCV, SI and SF in the observation group were significantly lower than those in the control group, and the level of TIBC was significantly higher than that in the control group, with statistical significance (P < 0.05). Conclusion H.pylori infection rate was not related to gender, and there were obvious ethnic clusters. H.pylori infection is associated with IDA in children and may be a risk factor for IDA. Therefore, routine H pylori monitoring and anti-H.pylori treatment should be included in the clinical treatment of IDA to obtain better clinical outcome. -
