BACKGROUND & AIMS: Organ donors are a potential source of transmissible disease after transplantation. The aim of this study was to evaluate the risk of acquiring hepatitis B among transplantation recipients of livers from donors without serum hepatitis B surface antigen (HBsAg) but with antibody to hepatitis B core antigen (anti-HBc).
The transplantation experience of four centers between 1989 and 1994 was reviewed. Recipients of livers from 674 donors were considered informative for hepatitis B virus transmission.
Hepatitis B developed in 18 of 23 recipients of livers from anti-HBc-positive donors (78%) compared with only 3 of 651 recipients of anti-HBc-negative donor livers (0.5%) (P < 0.0001). HBsAg persisted in all recipients with donor-related hepatitis B. Liver histology showed chronic hepatitis of moderate severity in 2 of 13 recipients at 1 year and 5 of 8 recipients between 1.6 and 4.5 years from transplantation. Liver transplantation from an anti-HBc-positive donor was associated with decreased 4-year survival (adjusted mortality hazard ratio of 2.4; 95% confidence interval, 1.4-4.0).
De novo posttransplantation hepatitis B infection occurs at a high rate in recipients of donors with anti-HBc. Transmission of hepatitis B through transplantation suggests that the virus may persist in the liver despite serological resolution of infection.
器官捐献者是移植后可传播疾病的潜在来源。本研究的目的是评估在接受无血清乙肝表面抗原(HBsAg)但有乙肝核心抗体(抗-HBc)的供体肝脏移植的受者中感染乙型肝炎的风险。
回顾了四个中心在1989年至1994年期间的移植经验。来自674名供体的肝脏受者被认为对乙肝病毒传播情况具有参考价值。
23名接受抗-HBc阳性供体肝脏移植的受者中有18名发生了乙型肝炎(78%),相比之下,651名接受抗-HBc阴性供体肝脏移植的受者中只有3名发生了乙型肝炎(0.5%)(P<0.0001)。所有与供体相关的乙型肝炎受者的HBsAg均持续存在。肝脏组织学检查显示,13名受者中有2名在移植后1年出现中度慢性肝炎,8名受者中有5名在移植后1.6至4.5年出现中度慢性肝炎。接受抗-HBc阳性供体的肝脏移植与4年生存率降低相关(调整后的死亡风险比为2.4;95%置信区间为1.4-4.0)。
在接受抗-HBc阳性供体肝脏移植的受者中,移植后新发乙型肝炎感染的发生率很高。通过移植传播乙型肝炎表明,尽管感染在血清学上已得到缓解,但病毒可能仍在肝脏中持续存在。
