Intramuscular hepatitis B immunoglobulins for reinfection control after liver transplantation: a cost-saving alternative

Abstract

Aim: We explore the effectiveness and cost–effectiveness of intramuscular versus intravenous hepatitis B immunoglobulins (HBIG-IV vs HBIG-IM) to prevent reinfection with the hepatitis B virus after orthotopic liver transplantation. Patients & methods: Overall, 14 patients had orthotopic liver transplantation in 2003–2013 at Ghent University Hospital for HBV-related liver disease. On average 32 months after transplantation patients switched from high-dose HBIG-IV to low-dose HBIG-IM, always in combination with a nucleos(t)ide analog. Results: Seven patients were switched so far. No significant differences between HBIG-IV and HBIG-IM were found in HBsAg and hepatitis B virus-DNA. Conclusion: Switching patients from HBIG-IV to HBIG-IM can be done safely if well monitored. Net yearly savings for the healthcare payer were €5000 for each patient switched to HBIG-IM.
