The prevalence of Helicobacter pylori (HP) IgG antibodies was analysed in a group of 142 asymptomatic children (group A) and in 31 pediatric patients (group B) with recurrent abdominal pain. HP IgG antibodies were measured by a commercially available fluorescence-enzyme immuno-assay test (Heloritest IgG, Fa Eurospital). In asymptomatic children the prevalence of HP IgG antibodies increased significantly with age from 17% with 6 years to more then 40% with 14 years. A higher prevalence of HP IgG antibodies was found in children living in more crowded housing conditions. Comparing the number of HP IgG positive children in group B (58%) to a matched population from group A (35%) no statistically different prevalence rates were found. Thus HP IgG antibodies are found in similar frequencies, in both, symptomatic and asymptomatic children. Therefore the presence of HP-IgG antibodies does not necessarily indicate that the HP infection is the cause for the recurrent abdominal pain in these children.
对142名无症状儿童（A组）和31名患有复发性腹痛的儿科患者（B组）进行了幽门螺杆菌（HP）IgG抗体患病率分析。采用市售荧光酶免疫测定试验（Heloritest IgG，Fa Eurospital）检测HP IgG抗体。在无症状儿童中，HP IgG抗体患病率随年龄显著增加，6岁时为17%，14岁时超过40%。居住在住房条件更拥挤环境中的儿童HP IgG抗体患病率更高。将B组中HP IgG阳性儿童的数量（58%）与A组匹配人群（35%）进行比较，未发现患病率有统计学差异。因此，有症状和无症状儿童中HP IgG抗体的出现频率相似。所以，HP-IgG抗体的存在不一定表明HP感染是这些儿童复发性腹痛的原因。
