Safety of ultra-rapid intravenous infusion of hepatitis B immunoglobulin in liver transplant recipients

Purpose

To evaluate the safety of institutional protocol for ultra-rapid hepatitis B immunoglobulin (HBIG) infusion (10,000 IU in 30 minutes) for hepatitis B virus prophylaxis in adult liver transplant recipients.

Methods

In this case-controlled study, prospectively recruited liver transplant recipients received ultra-rapid infusions of HBIG (10,000 units in 30 minutes) for 6 months. The historical control group consisted of patients who had received 1-hour HBIG infusions (conventional rapid infusion) for the precedent 6 months.

Results

We found that 1472 patients had received 5744 ultra-rapid HBIG infusions, whereas 1343 patients had received 5200 conventional rapid HBIG infusions. Adverse side-effects were observed after 7 (0.13%) and 9 (0.16%) infusions, respectively (P = .763). The number of infusions per month increased significantly, from 878 ± 34 before the introduction of ultra-rapid infusion to 957 ± 29 afterwards (P < .001), an increase of 10.5%. The maximal capacity of HBIG infusions per day in the outpatient clinic increased from 53 for conventional rapid infusion to 65 for ultra-rapid infusion, without expansion of the outpatient facility or equipment.

Conclusions

Nearly all adult liver recipients able to tolerate 1-hour infusions of HBIG can also tolerate ultra-rapid infusions well. Thus, it seems to be reasonable to perform ultra-rapid infusion protocol widely for patient convenience.
