Use of organs from donors testing positive for hepatitis B virus (HBV) may safely expand the donor pool. The American Society of Transplantation convened a multidisciplinary expert panel that reviewed the existing literature and developed consensus recommendations for recipient management following the use of organs from HBV positive donors. Transmission risk is highest with liver donors and significantly lower with non-liver (kidney and thoracic) donors. Antiviral prophylaxis significantly reduces the rate of transmission to liver recipients from isolated HBV core antibody positive (anti-HBcþ) donors. Organs from anti-HBcþ donors should be considered for all adult transplant candidates after an individualized assessment of the risks and benefits and appropriate patient consent. Indefinite antiviral prophylaxis is recommended in liver recipients with no immunity or vaccine immunity but not in liver recipients with natural immunity. Antiviral prophylaxis may be considered for up to 1 year in susceptible non-liver recipients but is not recommended in immune non-liver recipients. Although no longer the treatment of choice in patients with chronic HBV, lamivudine remains the most cost-effective choice for prophylaxis in this setting. Hepatitis B immunoglobulin is not recommended.

In the United States (U.S.), organ donation has plateaued at approximately 8000 deceased donors per year since 2004 and 5800 living donors per year since 2006. Overall, the number of organs transplanted in the U.S. has reached a plateau of approximately 31 000 per year. In contrast, the recipient waiting list has steadily increased to over 122 000 candidates (2). Consequently, novel approaches to safely expand the organ supply are desperately needed. Donation after circulatory death has emerged to be a significant portion of the U.S. donor population (1–3). Likewise, living donation from unrelated ‘‘altruistic’’ donors and paired kidney exchanges has also increased (1,4,5). Use of organs from donors with infections that can be prevented or easily managed in the recipient is another potential source to expand the donor pool. In this regard, individuals who test positive for hepatitis B virus (HBV) should be considered for deceased or living donation. The risk of transmission can be significantly reduced with prophylaxis. In the event of transmission, HBV can be readily managed utilizing similar antiviral therapeutic approaches as in patients with chronic HBV who undergo transplantation. This document reviews the literature regarding liver, kidney, and thoracic transplantation from donors with HBV infection and outlines recommendations for the use of such organs and subsequent recipient management. rates (2–8%) in Mediterranean countries and Japan; and high rates (8–20%) in Southeast Asia and sub-Saharan Africa (9,10). Similarly, the prevalence of anti-HBc positive liver donors also varies geographically: 2–9% in the U.S.; 7–12% in Europe and Japan; and 53–57% in China and Taiwan (11). HBV virology and diagnostics HBV is a double-stranded enveloped DNA virus of the family Hepadnaviridae. Although HBV primarily replicates within hepatocytes, extrahepatic replication may also occur (7,8). Furthermore, HBV DNA may be detected in the bloodstream with viremia surpassing >109 IU/mL. Consequently, the risk of transmission is highest with liver allografts but also may occur with other transplanted organs. The natural course of HBV infection has been fully reviewed elsewhere (12,13). Testing for HBV serologic markers is essential in the diagnosis of HBV infection. The interpretation of HBV serologic markers is summarized in Table 1. The presence of HBV DNA, hepatitis B surface antigen (HBsAg), and hepatitis B e antigen (HBeAg) are markers of active infection and IgM hepatitis B core antibody (IgM anti-HBc) is a marker of acute or reactivated infection. The presence of hepatitis B surface antibody (anti-HBs) is a marker of immunity. Finally, the presence of hepatitis B core antibody (anti-HBc) in the absence of HBsAg may represent a falsepositive result, past exposure to HBV with resolved or resolving infection, or rarely occult chronic HBV infection with detectable HBV DNA. Methods To develop consensus recommendations regarding the use of organs from HBV positive donors, the American Society of Transplantation assembled an expert group with representatives from the following adult and pediatric transplant disciplines: infectious diseases, hepatology, nephrology, pulmonary, cardiology, pharmacy, and organ procurement. Working groups were formed to review the epidemiology of HBV in transplantation and the impact of HBV positive donors in kidney, liver, and thoracic transplantation. Each working group brought forth recommendations to the overall group. A systematic literature review was performed using PubMed with the following search terms: hepatitis B, transplant, donor, outcome, and transmission. The GRADE system (6) was used to measure the strength of recommendations as strong or weak and the quality of evidence as high, moderate, or low. Consensus was reached via small and large group teleconferences. Background HBV epidemiology The use of donors who test positive for HBV is essential to maximizing the potential deceased donor pool as approximately one-third of the global population has serological evidence of past or current HBV infection including 350– 400 million people with chronic HBV infection (7,8). The prevalence of chronic HBV infection in the general population differs dramatically between regions with low rates (2%) in Western Europe and the U.S.; intermediate American Journal of Transplantation 2015; 15: 1162–1172 HBV immunization The HBV vaccine provides a significant level of protection against HBV infection, particularly in those who achieve protective antibody response (anti-HBs concentration of >10 IU/mL) before HBV exposure. In immunocompetent individuals, vaccination is thought to provide lifelong immunity even if anti-HBs titers wane. However, in immunocompromised individuals, maintenance of a protective anti-HBs titer may be necessary for ongoing protection (14). Whenever possible, the vaccine series should be given prior to transplantation in non-immune individuals since the vaccine is less effective after transplantation (15–18). The higher dose (40 mg antigen per dose) vaccine is recommended in the pretransplant setting in hemodialysis patients and other immunocompromised hosts due to decreased response rates with standard dosing. Children under the age of 18 years who do not seroconvert with standard dosing can receive vaccine with 20 mg antigen per dose as this dose has been shown to be immunogenic in children and adolescents with chronic kidney disease (19). The higher dose vaccine is also recommended in transplant recipients. Serologic testing of anti-HBs 1–2 months after completion of the vaccine series should be performed to confirm immunity or the need for repeating vaccination (20–22). 1163 guide.medlive.cn Huprikar et al Table 1: Interpretation of serologic tests for HBV adapted from (86) HBsAg negative anti-HBc negative anti-HBs negative No infection or immunity HBsAg negative Natural immunity recipients demonstrated higher rates of HBV recurrence with hepatitis B immunoglobulin (HBIG)/lamivudine (6.1%) compared to HBIG/hgbNA (1%) (29). As a result of effective antiviral therapy, use of HBIG passive immunization has decreased in LT recipients with chronic HBV, and some centers have stopped using HBIG altogether (30). Excellent outcomes are also observed in kidney and heart transplant recipients with chronic HBV who are managed with antiviral therapy alone (31). anti-HBc positive anti-HBs positive HBsAg negative Vaccine immunity anti-HBc negative anti-HBs positive HBsAg positive Acute infection anti-HBc positive IgM anti-HBc positive anti-HBs negative HBsAg positive Chronic infection anti-HBc positive IgM anti-HBc negative anti-HBs negative HBsAg negative Four possible interpretations: anti-HBc positive 1. Resolved infection and immune (most common) anti-HBs negative 2. No infection or immunity (falsepositive anti-HBc) 3. Occult chronic infection 4. Resolving acute infection Chronic HBV and transplantation The primary goal of treatment in patients with chronic HBV is virologic suppression. Posttransplant patient and graft survival have improved dramatically with effective antiviral therapy (23). Currently approved agents are summarized in Table 2 (12). Historically, lamivudine was the primary antiviral agent used for the treatment of chronic HBV both before and after transplantation. More recently, highly potent oral nucleos(t)ide analogs with a high genetic barrier to resistance (hgbNA) such as entecavir and tenofovir have emerged as the preferred agents. Entecavir and tenofovir are both safe and effective as once daily oral therapy and are now considered superior to lamivudine because of very low resistance rates (<1%) in treatment na€ıve patients (24–28). Furthermore, a systematic review of liver transplant (LT) 1164 Organ procurement organization practices: Donor HBV testing and organ use In the U.S., the current policy of the Organ Procurement Transplant Network (OPTN) requires that all organ procurement organizations (OPOs) perform deceased donor testing for HBsAg and anti-HBc (32). However, some OPOs perform additional donor HBV testing that is not mandated by OPTN to guide decisions about organ donation. Although specific data on the frequency in which donor organs are declined due to donor HBV testing results are lacking, decisions to utilize anti-HBcþ organs are often guided by additional tests with some OPOs routinely or reflexively performing IgM anti-HBc, anti-HBs, and/or HBV nucleic acid testing (NAT). These results are made available rapidly for transplant centers that utilize this information in decision-making. If the donor is IgM anti-HBc or HBV NAT positive, many OPOs and transplant centers currently do not accept such organs for donation due to concern for acute, reactivated, or occult chronic HBV infection in the donor. When the donor is anti-HBc IgG positive, some OPOs and transplant centers will accept such organs but there is no consistent approach to recipient management. It is debatable whether these additional tests are helpful in further stratifying transmission risk from an anti-HBcþ donor without features of clinical hepatitis. For example, there are no data to suggest that the anti-HBs status of an HBsAg– anti-HBcþ donor impacts the risk of HBV transmission to recipients yet this information is anecdotally used to assess donor acceptability. OPOs and transplant centers in the U.S. rarely use organs from HBsAgþ donors. OPTN policy requires that potential living donors are tested for HBsAg, anti-HBs, and anti-HBc (33). Potential living donors who are anti-HBcþ or HBsAgþ should undergo further testing with HBV DNA and evaluation for chronic HBV infection prior to organ donation consideration. Review of literature: Isolated anti-HBcþ donors The risk of HBV transmission from anti-HBcþ HBsAg– donors is observed mainly in liver transplant recipients. Transmission is significantly lower in kidney transplant recipients and essentially negligible in thoracic transplant recipients. Data are limited by variability in reporting donor and recipient transmission risk factors. There is also significant variation in the definition of HBV transmission ranging from the acquisition of anti-HBs and/or anti-HBc alone to the acquisition of HBsAg or detection of HBV DNA.

In this study, the onset of DNH ranged from 2 to 39 months after transplantation. In a more recently published review, the rates of DNH without prophylaxis were 58% (81/140) in HBV non-immune; 18% (6/34) in previously vaccinated; 14% (5/35) in isolated anti-HBcþ; and 4% (3/70) in naturally immune recipients (35). It should be emphasized that the absence of HBV DNA in donor serum does not preclude transmission of HBV to liver recipients (36). De novo HBV from anti-HBcþ donors with prevention strategy: Several preventive strategies have been employed to prevent DNH infection in HBsAg– recipients. A survey of LT programs conducted in 2007 revealed that indefinite antiviral therapy was the most frequent treatment strategy with lamivudine as the preferred antiviral agent and significant variation in HBIG usage (37). Four studies have reviewed the risk reduction associated with antiviral and/or HBIG prophylaxis (11,34–36). In the most recently published review (35), prophylaxis (lamivudine and/or HBIG) reduced rates of DNH from 58% to 11% in HBV nonimmune recipients; 18% to 2% in previously vaccinated recipients; and 14% to 3% in isolated anti-HBcþ recipients although the difference was not statistically significant in this final group. Prophylaxis did not further reduce the risk of DNH in naturally immune recipients (3% vs. 4%). However, another review (11) demonstrated a lower risk of DNH in anti-HBcþ recipients who received prophylaxis (3.4% vs. 15.2%). The lowest rate of DNH was observed in vaccinated recipients who received prophylaxis (11,35,38). The importance of adherence to antiviral prophylaxis was noted in a study where DNH was observed in five patients who were not adherent to lamivudine (39). Liver transplantation Although significant risk reduction of DNH is observed with lamivudine, the benefit is marginal with HBIG monotherapy (35). Furthermore, the addition of HBIG does not confer superior protection to lamivudine alone as Saab et al demonstrated a DNH rate of 2.7% with lamivudine prophylaxis compared to 3.6% with lamivudine plus HBIG (34). This finding was also confirmed in a systematic review (11) and in a single center study of 45 patients that demonstrated complete protection against DNH with lamivudine alone (40). De novo HBV from anti-HBcþ donors without prevention strategy: There is a significant risk of de novo HBV (DNH) in HBsAg– LT recipients of anti-HBcþ donor livers (11,34–36). Methods for the detection of post-LT DNH vary but typically rely on the new appearance of HBsAg or HBV DNA. Yen et al identified 90 cases of DNH among 194 liver recipients who did not receive HBIG or antiviral prophylaxis (36). The majority of transmissions (82/ 90) occurred in HBV non-immune recipients and DNH occurred in 77% (82/107) of these recipients. However, DNH also occurred in 18% (4/22) of previously vaccinated recipients and in 13% (4/31) of isolated anti-HBcþ recipients. DNH did not occur in any (0/34) naturally Since entecavir and tenofovir have supplanted lamivudine in the treatment of chronic HBV, many centers are now using entecavir and tenofovir in recipients of anti-HBcþ donors (41,42). Although anecdotes of lamivudine-resistant HBV transmission are described with lamivudine prophylaxis (39), the use of lamivudine in recipients of anti-HBcþ donors is still relevant. A retrospective study of 119 LT patients without chronic HBV who received anti-HBcþ livers showed minimal differences in DNH rates when comparing lamivudine (5/62, 8%) with adefovir (5/33, 15%), tenofovir (0/3), or entecavir (0/1) (42). Furthermore, a recent study used a Markov model to demonstrate that lamivudine * Dose adjustment required for renal impairment. American Journal of Transplantation 2015; 15: 1162–1172 1165 guide.medlive.cn Huprikar et al remains the most cost-effective option for preventing DNH in the context of anti-HBcþ donors (43). Kidney transplantation The reported risk of DNH in HBV na€ıve kidney recipients ranges from 0% to 27% (44). The risk of transmission is influenced by recipient HBV immunity and possibly by prophylaxis (45). In a recent review of nine studies with 1385 HBsAg– kidney recipients from anti-HBcþ donors (46), new HBV serologic markers were observed in only 45 (3.2%) patients. Although this study did not explore the influence of recipient anti-HBs status and use of prophylactic therapy, the rate of HBsAg acquisition was only 0.28% (4/1385) with no evidence of symptomatic hepatitis. Patient and graft outcomes were not worse among the patients with HBsAg acquisition or evidence of anti-HBs or anti-HBc seroconversion. The largest single study reported the incidence of anti-HBc conversion in kidney recipients from the United Network for Organ Sharing (UNOS) database with posttransplant surveillance intervals of 6, 12, 24, and 36 months. The incidence of anti-HBc seroconversion with anti-HBcþ donors was higher compared to anti-HBc– donors at 0.011 (95% CI 0.0070–0.0182) and 0.005 (95% CI 0.0047–0.0060) cases per year (p < 0.002), respectively (47). However, HBsAg acquisition was similar and occurred at a rate of 0.001 (95% CI 0.003–0.005) and 0.003 (95% CI 0.0025–0.0035) from anti-HBcþ and antiHBc– donors, respectively. HBV vaccination prior to transplant, with target anti-HBs titers >10 IU/L, has been demonstrated to be protective for renal recipients of anti-HBcþ donors (45,48,49). Rarely, individuals have had asymptomatic anti-HBc seroconversion following transplantation from anti-HBcþ donors. However, it is not clear if this truly represents DNH. Clinical hepatitis has not been noted in immunized individuals following kidney transplantation (KT) from anti-HBcþ donors, possibly due to partial protection from vaccination (50,51). Whether higher target levels of antibody will convey greater protection, as shown in LT recipients (52), is unclear. However in another series, the risk of anti-HBc seroconversion was reported to be 4% when anti-HBs titers were >100 IU/L compared to 10% when <100 IU/L(53). In another study (54) anti-HBc or anti-HBs seroconversion rates were similar in immunized and non-immunized recipients although the nonimmunized recipients were treated with HBIG. Other information regarding the use of HBIG in kidney recipients from anti-HBcþ donors is limited, and it is unknown if there is any benefit for recipients who have pre-existing antibody, especially if the donor is surface antigen and/or DNA negative (49,54–56). Although non-immune recipients of antiHBcþ kidneys who do not receive antiviral prophylaxis may benefit from HBIG (49,54) data demonstrating this benefit are lacking. The use of antiviral prophylaxis is rarely reported. In a 1166 single center observational study of 46 kidney or pancreas recipients of anti-HBcþ organs, there was no evidence of HBV transmission after a median of 36 months of follow-up (57). Immune recipients were not treated whereas the others were treated with lamivudine for 1 year. There is likely no role for HBIG in the setting of antiviral prophylaxis although this has not been studied. Thoracic transplantation Five studies with 122 transplantations provide data on the risk of transmission from anti-HBcþ heart donors (58–62). Early studies reported on patients without prophylaxis and did not reveal any HBV transmission in over 80 patients; some of whom were likely vaccinated prior to transplant (58–60,62). A later study included 33 donor/recipient pairs of which five received 6 months of lamivudine prophylaxis posttransplant (61). One anti-HBs– recipient did not receive prophylaxis and developed clinically significant DNH at 10 months posttransplant. Two others (one received lamivudine prophylaxis) seroconverted anti-HBs but without evidence of clinical hepatitis. Thus, the incidence of donor-transmitted clinically significant DNH was 1/33 or 3% in this study. Three studies that included 369 transplantations provide data on the outcomes from anti-HBcþ lung donors (63–65). An analysis of UNOS data compared the results of 13,233 recipients of organs from anti-HBc– donors with 333 recipients of anti-HBcþ organs for lung and heart-lung transplantation (63). Although one-year mortality was higher in the anti-HBcþ donor group in unadjusted analysis, there was no significant difference in five-year mortality, and anti-HBcþ donor status was not an independent risk factor for one-year or five-year mortality in the multivariable analysis. Regarding the one-year unadjusted mortality, the authors postulated that decompensated patients with urgent need for transplantation may have been more likely to receive anti-HBcþ donor organs. Two studies evaluated HBV transmission in the context of either pretransplant vaccination or posttransplant lamivudine prophylaxis (64,65). The first study evaluated 29 recipients of anti-HBcþ donor lungs who completed the full series of HBV vaccination. Although anti-HBs response was not confirmed, no cases of HBV transmission were reported and no differences in 1-year survival were found compared with recipients of anti-HBc– donor lungs (65). In the second study, none of the seven recipients who took 12 months of lamivudine prophylaxis after receiving an anti-HBcþ donor lung had evidence of DNH although pretransplant HBV vaccination and serostatus of the recipients were not reported (64). Review of literature: HBsAgþ donors While organs from HBsAgþ donors are not routinely transplanted in the U.S., there is evidence that patient and graft outcomes are acceptable with appropriate recipient American Journal of Transplantation 2015; 15: 1162–1172 guide.medlive.cn Transplantation From Hepatitis B Virus–Positive Donors management. Previous guidelines have suggested consideration of organs from HBsAgþ donors in urgent non-renal transplant candidates with HBIG/antiviral prophylaxis and informed consent (31). Consideration should also be made in endemic regions where potential donors are frequently HBsAgþ. Liver transplantation Transplantation of HBsAgþ livers into three recipients with chronic hepatitis B was described in one series (66). HBsAg persisted after transplant despite treatment with HBIG and antiviral therapy. Two of the recipients were co-infected with hepatitis Delta virus (HDV) and HDV relapsed in the setting of persistent HBsAg positivity and hepatitis. The third recipient was treated with HBIG, lamivudine, and adefovir and had stable graft function with negative HBV DNA. In a single center study from Italy, HBsAgþ livers were used in ten anti-HBcþ recipients (six with chronic HBV). All ten were treated with antiviral prophylaxis, and there was no evidence of DNH (67). A retrospective analysis of UNOS data reviewed the outcomes in 92 recipients of HBsAgþ livers (68). Although HBsAgþ livers were more likely to be imported or used in Model for EndStage Liver Disease (MELD) exception cases, there were no differences in patient or graft survival when compared to recipients of HBsAg– livers. In a single center study from China (69), 23 recipients of HBsAgþ livers were followedup for 10–38 months. The patient and graft survival rates were 78.3% (18/23) and 73.9% (17/23), respectively. Although the recurrence rate of HBV infection was 100% (23/23) and all patients remained HBsAgþ, no liver dysfunction, graft loss, or death was found to be related to the recurrence of HBV infection. Use of HBsAgþ donor livers should only be considered when significant donor liver disease has been ruled out by histological examination. Kidney transplantation The successful use of deceased and living donor HBsAgþ kidneys has been described in 104 HBV immune (antiHBsþ) recipients (70). Prevention strategies included a heterogeneous mix of vaccine, HBIG, and antiviral regimens although vaccine alone was used in 27 patients (70). Jiang et al described 65 anti-HBsþ kidney recipients who received HBsAgþ kidneys. HBIG was administered on the day of surgery and repeated at 1 month. For seven recipients of HBV DNAþ grafts, HBIG was given weekly for 3 months and lamivudine was given for 6 months. After a mean follow-up of 30 months, only one recipient acquired HBsAg but without liver injury or detectable HBV DNA (55). Tuncer et al described no DNH in 35 HBV immune (anti-HBs >10 IU/L) patients who underwent KT from HBsAgþ, HBV DNA negative living donors (71). Of considerable interest, HBIG and antiviral prophylaxis was not utilized. In another study, four naturally immune recipients were also treated with 1 year of lamivudine with no evidence of HBV transmission (57). In a recent study, the patient and graft survival after a median of 58.2 months was not different in American Journal of Transplantation 2015; 15: 1162–1172 HBsAg– recipients with anti-HBs titers >100 IU/L regardless of whether their graft was acquired from a HBsAgþ or HBsAg– donor (72). None of the 43 recipients of an HBsAgþ graft acquired HBV including 20 patients who received no prophylaxis. The successful use of HBsAgþ kidneys has also been demonstrated in HBsAgþ recipients (73). Of note, there is a report of fatal fulminant HBV 16 months after KT in a previously immunized (anti-HBsþ) recipient from an HBsAgþ donor. Although HBIG and a supplemental dose of HBV vaccine were administered, antiviral prophylaxis was not given (74). Thoracic transplantation Limited data exist for the use of HBsAgþ donors in heart transplantation. Most available data are published by one group in Taiwan with the apparent inclusion of the same subjects in more than one publication (62,75,76). Of at least 36 reported recipients of HBsAgþ donor hearts, HBsAg acquisition was observed in two recipients. HBV transmission occurred in one of three anti-HBs– recipients although the HBIG protocol was not completed in this patient. One of the seven recipients who were anti-HBcþ prior to transplant and received an HBsAgþ organ developed acute HBV, but it is unclear if this was reactivation of recipient or donor HBV. In contrast, HBV transmission was not observed in the 23 anti-HBsþ recipients. In a post-hoc analysis of a limited-access dataset of the United Network for Organ Sharing database from 2000 to 2010, anti-HBcþ donor status did not significantly affect overall survival of thoracic transplant recipients (77). These limited data suggest that effective pretransplant vaccination and possibly posttransplant HBIG prophylaxis can prevent HBV transmission from HBsAgþ donor hearts. No data exist for the use of HBsAgþ donors in lung transplantation. Review of literature: Monitoring No studies have been performed to assess the costeffectiveness or optimal frequency and type of monitoring for the development of DNH after transplantation. Recognition of DNH may be challenging since the onset of infection is not predictable and may be delayed for up to 5 years (78). For recipients of anti-HBcþ livers, most of the studies have described initial monitoring every 1–3 months for 1 year and every 3–6 months after 1 year. For non-liver recipients, optimal monitoring intervals have not been established. Review of literature: Pediatrics There is very limited evidence regarding the use of HBVþ donor organs in children. Seki et al reported a case of a 7-year-old boy with posterior urethral valves who received a KT from his mother who was HBsAgþ (79). The child completed HBV vaccination prior to transplant, and was anti-HBsþ 1 year later after which he was transplanted. During transplant, he received HBIG. Two years after transplant, he had no allograft rejection, kidney and liver function remained normal, and he continued to be HBsAg–. 1167 guide.medlive.cn Huprikar et al Wei et al reported on 21 patients from Taiwan (age range of 11–50 years) who underwent KT from 12 HBsAgþ deceased donors (80). Four (19%) of the 21 recipients were also HBsAgþ prior to transplant. There was no significant difference in mortality or graft failure between the recipient group that was HBsAgþ before transplant and the patients who were HBsAg– before transplant. However, two HBsAg– patients became HBsAgþ after transplant, and both died. Although the youngest recipient in the study was 11 years, the total number of children (<18 years) included and outcomes were not specified. Recommendations General 1. All transplant candidates should be tested for HBV (HBsAg, anti-HBs, and anti-HBc) to optimize risk assessment and guide management (strong recommendation; moderate quality of evidence). 2. Before transplantation, HBV vaccination is recommended for all non-immune (anti-HBs–) transplant candidates (strong; moderate). There is currently insufficient evidence to support or refute the use of anti-HBc þ positive or HBsAgþ organs in pediatric KT recipients. In contrast to other organ transplants, KT is rarely lifesaving in the acute setting since dialysis is typically an option for children with end stage kidney disease which allows the potential recipient to be selective towards high-risk donors. However, as more children with end stage kidney disease are becoming highly sensitized, the potential relative benefit of transplanting a kidney from an anti-HBcþ donor into a highly sensitized HBV immune child may have to be increasingly considered on an individualized case basis. 3. After transplantation, HBV vaccination is recommended for all non-immune transplant recipients (strong; low). 4. Recipients with chronic HBV infection should be managed according to existing guidelines irrespective of the donor HBV status (strong; moderate). 5. Organs from HBsAg– anti-HBcþ donors regardless of donor anti-HBs status should be considered for all adult transplant candidates after an individualized assessment of the risks and benefits and appropriate patient consent (strong; moderate). Compared to pediatric KT, a relatively larger experience of outcomes after pediatric LT with anti-HBcþ organs exists. The majority of the reported data comes from Asia with a total of 100 patients and an additional three patients reported from Poland (38,52,81–85). Except for 19 cases from China, all patients received routine vaccination in infancy and after transplant. However, there was considerable variability in the targeted anti-HBs titer goals, which ranged from 20 IU/L to 1000 IU/L. Twenty-three of 103 (22.3%) pediatric recipients of anti-HBcþ donors developed DNH after being followed for 4–120 months posttransplant. Use of HBIG either peri-transplant or as part of posttransplant prophylaxis was variable across centers. Of note, 8 of 36 patients from a single center in Taiwan developed DNH prior to the implementation of peri-transplant HBIG, posttransplant lamivudine and vaccination (52). In another study, 11 of 19 patients who received living donor transplants from antiHBcþ donors developed DNH. Eight of the 11 had no evidence of anti-HBs prior to transplant (81). Overall, vaccination appeared to be the most consistently employed strategy in pediatric LT recipients who received an antiHBcþ organ and was associated with a DNH rate of 15.7%. Optimal methods for preventing DNH in the pediatric population cannot be delineated based on this data. Although advanced planning is required and the complexity of both peri-operative and post-operative care increases, it appears that appropriate recipient management may increase feasibility of using anti-HBcþ donor livers in children. In low HBV prevalence areas such as the U.S., the option of using an anti-HBcþ liver should be confined to emergent situations or other unique situations after careful consideration of risks and benefits. The optimal method of preventing DNH is unclear and will evolve based on further experience. 6. Organs from HBsAg– anti-HBcþ donors should only be considered in emergent settings for pediatric transplant candidates in low prevalence areas after an individualized assessment of the risks and benefits and appropriate patient consent (strong; low). 7. DNH should be considered with clinical hepatitis or detection of HBV DNA, HBsAg, or anti-HBc (strong; moderate). 8. Consultation with a hepatologist or infectious diseases specialist with transplant experience is recommended when considering accepting an organ from an antiHBcþ or HBsAgþ donor or when there is concern for DNH (strong; low). 1168 Liver transplant recipients from anti-HBcþ HBsAg– donors (Figure 1) 9. Indefinite antiviral prophylaxis is recommended in HBV susceptible (anti-HBc– anti-HBs–) liver transplant recipients (strong; moderate). 10. Antiviral prophylaxis is recommended in recipients with vaccine immunity (anti-HBc– anti-HBs þ) (strong; moderate). 11. Antiviral prophylaxis is not recommended in recipients with natural immunity (anti-HBcþ anti-HBs þ) (weak; moderate). 12. Lamivudine is recommended as the most costeffective choice for prophylaxis (strong; moderate). 13. Entecavir or tenofovir may also be considered for prophylaxis due to their higher genetic barrier to resistance (strong; low).

Discontinuation of prophylaxis may be considered after 1 year in recipients with confirmed persistence of immunity (anti-HBs 10 IU/mL) (strong; low). 15. HBIG is not recommended (strong; moderate). 16. HBV DNA with or without HBsAg should be monitored every 3 months for 1 year and then every 3–6 months indefinitely in all recipients regardless of current or prior prophylaxis strategy (strong; low). Non-liver transplant recipients from anti-HBcþ HBsAg– donors (Figure 2) 17. Antiviral prophylaxis for up to 1 year may be considered in HBV susceptible (anti-HBc– anti-HBs–) recipients (weak; low). 20. HBIG is not recommended (strong; moderate). 21.

Organs from HBsAgþ donors may be carefully considered in all adult transplant candidates after an individualized assessment of the risk and benefits and appropriate patient consent (weak; low). 23. HBsAgþ livers should only be considered when significant donor liver disease has been ruled out by histology (strong; low). 24. Indefinite prophylaxis with entecavir or tenofovir is recommended for all recipients (strong; low). 18. Lamivudine is the recommended choice for prophylaxis (strong; moderate). 25. HBIG should be considered in all recipients when the anti-HBs titer is <100 IU/L (strong; low). 19. Antiviral prophylaxis is not recommended for recipients with natural (anti-HBcþ anti-HBsþ) or vaccine (anti-HBc– anti-HBsþ) immunity (strong; moderate). 26. HBV DNA with or without HBsAg should be monitored every 3 months for 1 year and then every 3–6 months indefinitely (strong; low).

Studies are needed in the following areas to improve the quality of evidence and strengthen the validity of the recommendations: 1. Donor and recipient risk factors for DNH. 2. The impact of further HBV testing of HBsAgþ or antiHBcþ donors on recipient management and outcomes. 3. Optimal choice and duration of prevention strategies for non-immune recipients for each organ type. 4. The need for prevention strategies in immune recipients for each organ type. 5. Optimal testing, frequency, and duration of monitoring for each organ type. 6. The safety of using HBsAgþ organs.
