Prevalence of Hepatitis A and B Markers and Vaccine Indication in Cirrhotic Patients Evaluated for Liver Transplantation in Spain

Efficacy of an accelerated double-dose hepatitis B vaccine regimen in patients with cirrhosis

The hepatitis B (HBV) vaccine is recommended in unvaccinated adults with cirrhosis, despite its low efficacy. We aimed to evaluate the response to a double-dose/accelerated vaccine schedule in patients with cirrhosis admitted into a hepatology ward. All patients with cirrhosis admitted to the hepatology ward without exclusion criteria were offered the HBV HBVAXPRO 40mcg vaccine at months 0, 1 and 2. Non-responders received a second cycle. We evaluated 468 patients and only 19% were seroprotected against HBV. In 196 patients without exclusion criteria for HBV vaccination, the per protocol response rate (anti-HBs >10 U/ml) was 23% after a first cycle and 59% after a second cycle. The overall response per intention to treat was only 23%. We have not identified predictors of response. Only one patient had a mild adverse event. Most patients with cirrhosis admitted in the hepatology ward are unprotected against HBV. Although a second HBV vaccination cycle increases the response rate, the poor overall response reinforces the implementation of HBV vaccination before the development of cirrhosis.

A new scheme with infusion of hepatitis B immunoglobulin combined with entecavir for prophylaxis of hepatitis B virus recurrence among liver transplant recipients

OBJECTIVE

Liver transplantation significantly increases recurrence of hepatitis B virus (HBV) among high-risk patients. Hepatitis B immunoglobulin (HBIG) and antiviral nucleotide analogues are effective prophylaxis reagents in preventing HBV recurrence. However, HBV recurrence still occurs with these treatments.

METHODS

To explore a more cost-effective prophylaxis protocol in patients after liver transplantation, we treated patients with an initial high dose of 10 000 IU HBIG during the anhepatic phase and a second high dose of HBIG at an optimal time point during surgery. The patients were treated with the traditional European protocol as a control, in which one dose of 10 000 IU HBIG was infused during the anhepatic phase and multiple doses of 10 000 IU HBIG were administered daily for 1 week after liver transplantation.

RESULTS

There were two mortalities among 50 patients treated with the new protocol and nine mortalities among 52 patients treated with the European protocol within 3 years after liver transplantation. The new prophylaxis method markedly improved the 3-year survival without HBV recurrence in 50 treated patients. However, there were five recurrences in 52 patients treated with the European protocol. High-risk factors such as HBV DNA+, positive hepatitis B e antigen, and hepatocellular carcinoma were all detected among five patients with HBV recurrence. The suppressed HBV recurrence was associated with significantly lower serum alanine aminotransferase and aspartate aminotransferase in the new protocol-treated patients tested at 1 month and 1 week after liver surgery compared with those treated with the European protocol.

CONCLUSION

Infusion of two high doses of HBIG during surgery in combination with entecavir significantly prevented HBV recurrence and improved the 3-year survival after liver transplantation.
