Pharmacokinetics and efficacy of intravenous or intramuscular hepatitis B immunoglobulins in prophylaxis of hepatitis B after liver transplantation.
The use of hepatitis B immunoglobulin (HBIg) combined with nucleos(t)ide analogues (NUCs) has improved outcomes in post-hepatitis B (PHB) liver transplant (LT), reducing the 1-year recurrence rate below 10%. The aim of this study was to evaluate efficacy and pharmacokinetics of prophylaxis with NUC(s) and intravenous (iv-) or intramuscular (im-) HBIg in 33 PHBLTs, transplanted for more than 1 year. ⋯ These results confirm an analogue efficacy and tolerance of iv- and im-HBIg combined with antivirals in prophylaxis of hepatitis B after LT. Anti-HBs titers three times higher than aimed and four weeks mean half-life could suggest the reduction of doses and the elongation of the interval of administration of im-HBIg.
