Abstract:

Objective To sum up the pathological and clinical features of hepatitis B infection after liver transplantation. Methods 56 patients after liver transplantation from June 2005 to December 2014 with hepatitis B infection were retrospectively analyzed for clinical data,hepatitis B markers,HBVDNA and liver biopsy pathologydata. Results The 56 patients with hepatitis B infection after liver transplantation included 38 males and 28 females ;the age ranged from 42 - 67 years(average age 52.6 years) ;the time of liver biopsy was 96 - 2 432 days, and biopsy was performed in 78 times. The postoperative hepatitis B infection in the group was < 1 year(32.15%),1 - 2 years(57.14%),2 - 3 years(7.14%)and > 3 years(3.57%),and 2 years the infection rate was 89.29%. The copies of HBV DNA is < 103 IU/ml(21.43%)、103 - 104 IU/ml(73.21%)and > 104 IU/ml(5.36%)respectively,and 2 patients which > 104 IU/ml infected after operation in 2 years. Serological HBsAg(-)、HBsAg(+)、HBsAg、HBeAg(+)and HBsAg、HBeAg、HBcAb(+)is 19.64%、57.14%、14.29% and 8.93%,respectively. The results of 78,including portal area moderate mononuclear cell infiltration,interface of inflammation,focal liver cell necrosis and apoptosis,liver cell frosted glassdegeneration,liver tissue deposition in the bile and periportal fibrosis. Theoccurrence rate is 83.33%、48.72%、92.31%、15.38%、41.03% and 15.38%. Batts-Ludwig activity classification 0、1、2 、3、4 is 15.38%、

29.49%24.36%19.23% and 11.54%,respectively. Hepatitis fibrosis stage 0、Ⅰ、Ⅱ、 Ⅲ and Ⅳ is 58.97%16.67%15.54%7.69% and 5.13%. The degree of hepatitis activity grading was correlatedwith the levels of hepatitis markers and HBV DNA,has nothing to do with time.Fibrosis stage was correlated withthe infection time,hepatitis markers and HBV DNA levels. Conclusions The main pathologic manifestations of hepatitis B infection after liver transplantation is liver cell injury,portal inflammation. The pathological examination can evaluate the activity and fibrosis staging of hepatitis B infection,which plays an important role in the differential diagnosis. Combined with the serum markers of HBV and the detection results of HBV DNA,the status of hepatitis B lesion can be determined and provides important references for clinical designation of treatment program.

摘要:

目的 总结肝移植患者术后乙型肝炎病毒(HBV)感染的病理学及临床特点。方法 回顾性分析天津市第一中心医院 2005 年 6 月至 2014 年 12 月行成人原位肝移植术后 56 例出现 HBV 感染患者肝穿活检病理和临床资料以及 HBV 标志物和 HBV DNA 情况。结果 56 例肝移植术后 HBV 感染患者中男性38 例,女性 28 例 ;年龄 42 ~ 67 岁,平均 52.6 岁 ;肝穿刺活检时间为术后 96 ~ 2 432 天,共行活检 78 例次。本组病例术后 HBV 感染时间术后< 1 年、1 ~ 2 年、2 ~ 3 年和> 3 年分别为 32.15%57.14%7.14% 3.57%,其中≤ 2 年感染率为 89.29%。HBV DNA 拷贝数< 103U/ml103 104 U/ml 和> 104U/ml 分别为21.43%73.21% 5.36%,其中 2 例> 104 U/ml 的患者均发生于术后≤ 2 年。血清学 HBsAg(-)、HBsAg(+)、HBsAg、HBeAg(+)、HBsAg、HBeAg、HBcAb(+)分别为 19.64%57.14%14.29% 8.93%78 例次肝穿刺活检的病理表现包括汇管区中等量单个核细胞浸润、界面性炎症、肝细胞灶性坏死及凋亡、肝细胞毛玻璃样变性、肝组织淤胆和汇管区纤维化,其发生率分别为 83.33%48.72%92.31%15.38%41.03% 15.38%。Batts-Ludwig 0、1、2、3、4 级 分 别 为 15.38%29.49%24.36%19.23% 11.54%,肝炎纤维化分期 0、Ⅰ、Ⅱ、Ⅲ和Ⅳ期分别为 58.97%16.67%15.54%7.69% 5.13%。肝炎活动度分级与肝炎标志物及 HBV DNA 水平有相关性,与时间无相关性。纤维化分期与感染时间、肝炎标

志物及 HBV DNA 水平具有相关性。结论 肝移植术后 HBV 感染的病理学表现以肝细胞损伤、汇管区炎症 为主,病理学检查可以对 HBV 感染的活动程度及纤维化分期进行准确评估,并在鉴别诊断中起重要作用,结合 HBV 血清学标志物及和 HBV DNA 检测结果可以准确判定 HBV 病变进展状态,为临床制定治疗方案提供重要参考依据。
