用ＰＣＲ法、快速尿素酶试验及组织学染色检查法检测３５例肝硬化患者和３２例胃十二指肠病患者的Ｈｐ感染率，分别为７１．４％与６５．６％，两组比较差异无显著性（Ｐ＞０．０５）。有肝功能损害者，Ｈｐ感染率较肝功能正常者高，分别为７９．３％与３３．３％（Ｐ＜０．０５）。认为肝硬化患者Ｈｐ感染率较高，后者可能是肝性脑病的危险因素之一 The prevalence of Hp infection in 35 patients with cirrhosis and 32 patients with gastroduodenal disease was 71.4% and 65.6% respectively by PCR, rapid urease test and histological staining test. There was no significant difference (P> 0.05). Those with impaired hepatic function had a higher Hp infection rate than those with normal liver function (79.3% vs. 33.3%, respectively) (P <0.05). Hp infection rates in patients with cirrhosis of the higher, the latter may be one of the risk factors for hepatic encephalopathy
