乙型肝炎后肝硬化胃粘膜病变发病因素探讨

探讨乙型肝炎后肝硬化胃粘膜病变发病因素。102例肝病或非肝病因伴有胃病行胃镜检查的患者，取胃窦小弯距幽门周围(2—3)cm处粘膜3块，分别做快速尿素酶试验及嗜伊红、品红染色，并行免疫组化检测幽门螺旋杆菌HPlgG型抗原。发现肝硬化组(LC组)与慢性肝炎组(HB组)有不同程度胃粘膜炎症达95．5％(42／4)、53．6％(15／28)；前者萎缩、肠化多于后者(P＜0．05)。上述两组乙型肝炎病毒(HBV)抗原表达率分别为81．8％(36／44)、53．6％(15／28)；前者多于后者(P＜0．05)。与非肝病胃病患者30例相比，LC组、HB组HP阳性率无明显差别(P＞0．05)。说明门脉高压及HBV是LC胃粘膜病变的主要发病因素。

Etiologic study of chronic hepatitis B post cirrhosis gastritic mucosal lesion

To investigate the etiology of chronic hepatitis B(HB)post cirrhosis gastritic mucosal lesion.In 102 patients diagnostic endoscopy was performed.Three gastric biopsies were taken within 2-3cm around the pylorus of gastric antra,urease detection,HE fuchsin staining and immunohistochemical analysis of Helicobacter pylori(HP) IgG antigen,HBsAg and HBcAg were performed separately.In cirrhosis group,95.5% of 44 patients (42/44) showed different extent of chronic inflammation of gastric mucosa 92.9%(26/28)in chronic hepatitis B group.In addition to chronic gastric mucous inflammation,the date of existence of gland atrophy or/and intestinal epithelialization is 33.3%(14/42) and 11.5%(3/26)respectively(P<0.05).The positivity of HBVAg in these two groups is 81.8%(36/44)and 53.6%(15/28)respectively(P<0.05).In these two groups the positive rate of HP in inflammatory gastric mucous is 69.0%(29/42)and 76.9%(20/26)respecctively,there is no obvious defference between them. Among the 42 patients with cirrhosis associated gastritis,19 were found to be esophageales varicosis positive,but the other 23 were not,the positivity of HP of these two groups was 73.7%(14/19)and 65.3%(15/23)(P>0.05).The result of analysis of the severity of HB associated gastritis indicated that the portal hypertensive cirrhosis in later stage of liver disease plays an important role in the development of this disease.The relationship between hepatitis B virus and this disease needs further investigation.HP is not the pathogeny of this disease.
