A combination of nucleos(t)ides and hepatitis B immunoglobulin (HBIg) has been found to be effective for the prevention of hepatitis B viral (HBV) reinfection after liver transplantation (LT), but its administration is costly, and not always available. We report the case of a male, 33-year-old cirrhotic patient who has tested positive for serum HBsAg, and HBeAg, with 9.04 × 10(7) copies/mL of HBV DNA. He suffered from acute liver failure and was near death before undergoing emergency LT. No HBIg was available at the time, so only lamivudine was used. He routinely received immunosuppression medication. Serum HBV DNA and HBsAg still showed positive post-LT, and the graft re-infected. Hepatitis B flared three months later. Adefovir dipivoxil was added to the treatment, but in the 24(th) mo of treatment, the patient developed lamivudine resistance and a worsening of the hepatitis occurred shortly thereafter. The treatment combination was then changed to a double dosage of entecavir and the disease was gradually resolved. After 60-mo of post-LT nucleos(t)ide analogue therapy, anti-HBs seroconverted, and the antiviral was stopped. By the end of a 12-mo follow-up, the patient had achieved sustained recovery. In conclusion, the case seems to point to evidence that more potent and less resistant analogues like entecavir might fully replace HBIg as an HBV prophylaxis and treatment regimen.
已发现核苷(酸)类似物与乙肝免疫球蛋白(HBIg)联合使用对预防肝移植(LT)后乙肝病毒(HBV)再感染有效,但其应用成本高昂,且并非总能获得。我们报告了一例33岁男性肝硬化患者的病例,该患者血清HBsAg和HBeAg检测呈阳性,HBV DNA为9.04×10⁷拷贝/毫升。他患有急性肝衰竭,在接受紧急肝移植前濒死。当时没有HBIg,因此仅使用了拉米夫定。他常规接受免疫抑制药物治疗。肝移植后血清HBV DNA和HBsAg仍呈阳性,移植物再次感染。三个月后乙肝复发。治疗中加用了阿德福韦酯,但在治疗的第24个月,患者出现拉米夫定耐药,此后不久肝炎病情恶化。然后治疗方案改为双倍剂量的恩替卡韦,疾病逐渐得到缓解。肝移植后核苷(酸)类似物治疗60个月后,抗-HBs血清学转换,抗病毒药物停用。在12个月的随访结束时,患者实现了持续康复。总之,该病例似乎表明有证据显示,像恩替卡韦这样更有效且耐药性更低的类似物可能会完全取代HBIg作为乙肝预防和治疗方案。
