Key Concepts: 1. The use of low-dose immunosuppressive therapy along with pre-and posttransplantation nucleos(t)ide therapy and posttransplantation hepatitis B immunoglobulin (HBIG) has yielded marked improvements in survival. 2. Lamivudine (Epivir-HBV), adefovir (Hepsera), entecavir (Baraclude), tenofovir (Viread), emtricitabine (Emtriva), and the combination drugs tenofovir ϩ emtricitabine (Truvada) and abacavir ϩ lamivudine (Epzicom) are effective nucleos(t)ide antiviral agents that, in some cases, may help reverse liver disease sufficiently to avoid transplant. 3. In posttransplantation patients, virus suppression with some combination of HBIG and the nucleos(t)ide agents may prevent graft loss and death or the need for a second transplant. 4. In both the pre-and posttransplantation setting, the goal of hepatitis B virus management is complete virus suppression. 5. The use of low-dose intramuscular HBIG is evolving, with studies showing that dosing and cost can be reduced by 50-300% with a customized approach. 6. Elimination of HBIG from the treatment paradigm is currently under evaluation and may be possible with the use of newer medications that have no or low resistance rates. 7. Although there is growing evidence that some types of combination therapy may decrease the chance that drug resistance will develop and increase the likelihood of long-term success in preventing graft loss and death, additional research will be required to determine which combinations will work well in the long term, and which will not. Liver In 2001, the patient sought care from a gastroenterologist for increased abdominal distension and increasing fatigue. An ultrasound of the abdomen showed a cirrhotic liver, with a large amount of ascites. An esophagogastroduodenoscopy revealed grade 2 varices with portal hypertensive gastropathy. His renal function was normal. Therapy with the following was initiated at the time of his medical evaluation: lamivudine (100 mg daily), Aldactone (100 mg daily), Lasix (40 mg daily), and propranolol (20 mg twice daily).After 1 year of therapy, laboratory values were as follows: AST 101 U/L, ALT 56 U/L, bilirubin 2.4 mg/dL, albumin 2.9 g/dL, and international normalized ratio of prothrombin time 1.4. HBV serologies were unchanged. He was lost to follow-up for the next 2 years, but he stated that he continued lamivudine therapy.In June 2003, he was transferred to a transplant center as a result of increased lethargy, encephalopathy (grade 2), and worsening ascites. Physical examination revealed mild confusion. Vital signs were as follows: heart rate 120 beats/min, blood pressure 100/65 mm Hg, and temperature 38.0°C. He had scleral icterus and severe muscle wasting. Abdominal examination showed moderate tense ascites. Table 1 lists laboratory data.The patient's Model for End-Stage Liver Disease score was 34. Because paracentesis revealed ascitic fluid white count of 6.3 ϫ 10 3 / L with 72% segmented neutrophils, ceftriaxone and albumin infusions were started. Ultrasonography showed a cirrhotic liver ...
