【摘要】 为探讨小儿幽门螺杆菌（ＨＰ）感染诊断的最佳手段，对９８例不同群体小儿用胃粘膜活检标本尿素酶快速诊断法、血清ＨＰ－ＩｇＧ测定法、胃液ＨＰ－聚合酶链反应（ＰＣＲ）法进行了ＨＰ感染的对比性研究。结果：三种方法在上消化道疾病组胃粘膜活检标本中ＨＰ感染阳性率分别为４２％、５４％、４８％，与非消化道疾病及健康小儿对照组差异有显著性意义（Ｐ＜０．００５）。结果表明：三种方法在检测ＨＰ的阳性率方面无明显差别，而胃液ＨＰ－ＰＣＲ法方法简单实用、敏感性和特异性均较好，可作为诊断ＨＰ感染的最佳方法之一。更多还原

【Abstract】 To search for the best diagnostic approach to Helicobacter pylori (HP) infection in children. The authors conducted a comparative study on gastric mucosa′s urease test, serum HPIgG antibody and gastric juice HPPCR in 98 children. The results showed that in the cases with upper gastrointestinal (GI) tract diseases, the urease test, HPIgG and HPPCR were positive in 42%、 54% and 48%, respectively. The difference among the groups with upper GI tract disorders, nonupper GI tract disorders and the healthy children was significant. Of the 3 diagnostic methods, HPPCR was found a simpler, more sensitive, and more practical one.更多还原
