Background: Hepatitis B virus (HBV) reactivation is well-recognized complication of rituximab. Although use of rituximab for sensitized patients continues to increase in kidney transplantation, the impact of rituximab dose on HBV reactivation remains unknown.

Method: We analyzed 336 HBsAg-negative/anti-HBc-positive patients who underwent living donor kidney transplantation between 2008 and 2015. Patients were categorized by rituximab dose (standard dose rituximab [375 mg/m2] vs. reduced dose rituximab [200 mg fixed dose] vs. control groups). All patients were observed for HBV reactivation, which was defined as the reappearance of hepatitis B surface antigen or HBV DNA.

Results: A total of 91 (27.1%) of them received rituximab for desensitization therapy (57 received standard dose and 34 received reduced dose rituximab). During the study period, 8 cases of HBV reactivation developed. Five of them received standard dose rituximab (8.8%) and 3 were control group (1.2%). No HBV reactivation occurred in reduced dose rituximab group. Standard dose rituximab was associated with the severity as well as the frequency of HBV reactivation. In standard dose rituximab group, two patients experienced HBV-related severe hepatitis, and one patient died due to hepatic failure. By contrast, no patients in control group experienced severe hepatitis. Standard dose rituximab (hazard ratio, 9.97; 95% CI, 2.27-43.87; P=0.002) and HBV surface antibody status (hazard ratio, 4.61; 95% CI, 1.09-19.52, P=0.038) were independent risk factors for HBV reactivation.

Conclusion: Standard dose rituximab for desensitization significantly increased the risk of HBV reactivation for patients with hepatitis B core antibody.
