Abstract

The development of effective nucleos(t)ide analogs (NAs) against hepatitis B virus (HBV) has improved the outcome of patients with chronic hepatitis B (CHB). This review updates issues related to the management of CHB patients included in special populations. Entecavir (ETV) and tenofovir (TDF) represent the currently recommended first-line NAs in patients with HBV decompensated cirrhosis. The combination of HBV immunoglobulin (usually for a finite duration) and NA is considered the standard of care for prophylaxis against HBV recurrence after liver transplantation. TDF is the best choice for hemodialysis patients and in patients with chronic kidney disease with nucleoside resistance. ETV and telbivudine are the preferred options in naïve renal transplant recipients and with low viremia levels, respectively. All hepatitis B surface antigen (HBsAg)-positive candidates should be treated with NAs before renal transplantation to achieve undetectable HBV DNA at the time of transplantation. Conventional interferon or NAs can also be used in children, on the basis of well-established therapeutic indication. Pregnant women at high risk of perinatal transmission could be treated with lamivudine, telbivudine or TDF in the last trimester of pregnancy. HBsAg-positive patients under immunosuppression should receive NA pre-emptively (regardless of HBV DNA levels) up to 12 mo after its cessation. In HBsAg negative, anti-HBc positive patients under immunosuppression, further studies are needed to form a final conclusion; however, it seems that anti-HBV prophylaxis is justified in such patients with hematological diseases and/or for those receiving rituximab-containing regimens, regardless of their anti-HBs or serum HBV DNA status.

Core tip: The management of hepatitis B virus (HBV) infection in special populations is reviewed. HBV patients with decompensated cirrhosis should receive nucleos(t)ides analogs (NAs) before and after liver transplantation. The choice of NA for patients with chronic kidney disease, renal transplant candidates and recipients depends on viremia levels, the severity of renal dysfunction and previous viral resistance. Children at the immune-active period may receive interferon or NAs. Pregnant women at risk of perinatal transmission should receive class B antiviral drugs or LAM. HBV patients receiving immunosuppressives should receive antiviral therapy based on HBV serological profile, HBV DNA detectability and intensity of immunosuppression.
