High Frequency Occult Hepatitis B Virus Infection Detected in Non-Resolved Donations Suggests the Requirement of Anti-HBc Test in Blood Donors in Southern China. Front Immunol 2021; 12:699217. [PMID: 34394093 PMCID: PMC8355616 DOI: 10.3389/fimmu.2021.699217] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Accepted: 07/12/2021] [Indexed: 02/04/2023] Open
Abstract
Background Most Chinese Blood Centers adopted mini pool (MP) nucleic acid testing (NAT) for HBV screening due to high cost of Individual donation (ID) NAT, and different proportions of MP-reactive but ID-non-reactive donations (MP+/ID-, defined as non-resolved donations) have been observed during daily donor screening process. Some of these non-resolved donations are occult HBV infections (OBIs), which pose potential risk of HBV transmission if they are not deferred. This study is aimed to further analyze these non-resolved donations. Methods The non-resolved plasma samples were further analyzed by serological tests and various HBV DNA amplification assays including quantitative PCR (qPCR) and nested PCR amplifying the basic core and pre-core promoter regions (BCP/PC; 295 base pairs) and HBsAg (S) region (496 base pairs). Molecular characterizations of HBV DNA+ non-resolved samples were determined by sequencing analysis. Results Of 17,226 MPs from 103,356 seronegative blood donations, 98 MPs were detected reactive for HBV. Fifty-six out of these 98 (57.1%) reactive MPs were resolved as HBV DNA+, but the remaining 42 pools (42.9%, 252 donations) were left non-resolved with a high rate (53.2%) of anti-HBc+. Surprisingly, among 42 non-resolved MPs, 17 contained one donation identified as OBIs by alternative NAT assays. Sequence analysis on HBV DNAs extracted from these OBI donations showed some key mutations in the S region that may lead to failure in HBsAg detection and vaccine escape. Conclusion A total of 53.2% of the non-resolved donations were anti-HBc+, and OBIs were identified in 40.5% of these non-resolved pools. Therefore, non-resolved donations with anti-HBc+ might pose potential risk for HBV transmission. Our present analysis indicates that anti-HBc testing in non-resolved donations should be used to identify OBIs in order to further increase blood safety in China.

Abstract
In 2016, the Transplantation Society of Australia and New Zealand, with the support of the Australian Government Organ and Tissue authority, commissioned a literature review on the topic of infectious disease transmission from deceased donors to recipients of solid organ transplants. The purpose of this review was to synthesize evidence on transmission risks, diagnostic test characteristics, and recipient management to inform best-practice clinical guidelines. The final review, presented as a special supplement in Transplantation Direct, collates case reports of transmission events and other peer-reviewed literature, and summarizes current (as of June 2017) international guidelines on donor screening and recipient management. Of particular interest at the time of writing was how to maximize utilization of donors at increased risk for transmission of human immunodeficiency virus, hepatitis C virus, and hepatitis B virus, given the recent developments, including the availability of direct-acting antivirals for hepatitis C virus and improvements in donor screening technologies. The review also covers emerging risks associated with recent epidemics (eg, Zika virus) and the risk of transmission of nonendemic pathogens related to donor travel history or country of origin. Lastly, the implications for recipient consent of expanded utilization of donors at increased risk of blood-borne viral disease transmission are considered.

Abstract
SkagenMany transplant programs utilize liver grafts from hepatitis-B core antibody (HBcAb)-positive and hepatitis-B surface antigen (HBsAg)-negative donors. However, there is risk for de novo hepatitis B (DNH) in recipients of these grafts. We reviewed 26 studies reporting the rates of DNH in recipients receiving HBcAb-positive liver grafts. Four hundred and sixty-two donor-recipient pairs were included to evaluate the risk of DNH stratified by the recipient's immune status to hepatitis B and type of prophylactic therapy given, if any. The rate of DNH was highest (58%) in the stratum of hepatitis-B (HBV) naïve recipients who did not receive prophylaxis. In HBV naïve recipients, prophylactic therapy (lamivudine and/or hepatitis-B immunoglobulin - HBIG) reduced DNH to 11% (odds ratio [OR] = 11.1, 95% CI 4.98-25, p < 0.0001 for DNH without prophylaxis). Recipients with hepatitis-B surface antibody (HBsAb) positivity had DNH rates of 18% without prophylaxis and 0% with prophylaxis (OR = 9.2, 95% CI 1.1-83.3, p = 0.039). Recipients with both HBsAb and HBcAb positivity had DNH rates of 4% without prophylaxis and 3% with prophylaxis (p = 1.00), while recipients with HBcAb positivity alone had DNH rates of 14% without prophylaxis and 3% with prophylaxis (p = 0.21). There was no significant difference between the types of HBV prophylaxis received whether lamivudine, HBIG or both. However, in the subgroup who received HBIG alone, rates of DNH were higher after cessation of HBIG prophylaxis compared to DNH rates with indefinite HBIG (p = 0.0002). In summary, the risk of DNH is highest for HBV naïve liver recipients from HBcAb-positive donors. Recipients who are HBV naïve as well as those recipients with isolated HBsAb positivity derive significant benefit from HBV prophylaxis after transplantation with a HBcAb-positive graft. The ideal prophylactic regimen for prevention of DNH is unclear, but based on our analysis of the literature, antivirals alone may suffice. More data are needed with the newer antivirals for hepatitis B.

Abstract
BACKGROUND & AIMS Although hepatitis B virus (HBV) transmission after liver transplantation of grafts from HBsAg-negative, anti-HBc positive donors is well established, the growing organ shortage favours the use of such marginal grafts. We systematically evaluated the risk of HBV infection after liver transplantation with such grafts and the effect of anti-HBV prophylaxis. METHODS We performed a literature review over the last 15 years identifying 39 studies including 903 recipients of anti-HBc positive liver grafts. RESULTS Recurrent HBV infection developed in 11% of HBsAg-positive liver transplant recipients of anti-HBc positive grafts, while survival was similar (67-100%) to HBsAg-positive recipients of anti-HBc negative grafts. De novo HBV infection developed in 19% of HBsAg-negative recipients being less frequent in anti-HBc/anti-HBs positive than HBV naive cases without prophylaxis (15% vs 48%, p<0.001). Anti-HBV prophylaxis reduced de novo infection rates in both anti-HBc/anti-HBs positive (3%) and HBV naive recipients (12%). De novo infection rates were 19%, 2.6% and 2.8% in HBsAg-negative recipients under hepatitis B immunoglobulin, lamivudine and their combination, respectively. CONCLUSIONS Liver grafts from anti-HBc positive donors can be safely used, preferentially in HBsAg-positive or anti-HBc/anti-HBs positive recipients. HBsAg-negative recipients should receive prophylaxis with lamivudine, while both anti-HBc and anti-HBs positive recipients may need no prophylaxis at all.

Abstract
Hepatitis C (HCV)-related end-stage liver disease is the most common indication for liver transplantation. Safe expansion of the donor pool with improved rates of deceased donation and more widespread use of living and extended criteria donation are likely to decrease wait list mortality. In addition, improved antiviral treatments and a better understanding of the delicate balance between under- and over-immunosuppression in this population are needed. Finally, when recurrent advanced fibrosis occurs, the criteria for patient selection for retransplantation remain widely debated. This article reviews the literature on these topics and the work being done in each area to maximize outcomes in patients receiving transplants for HCV-related cirrhosis.

Abstract
Hepatitis C (HCV) and hepatitis B (HBV) -related end-stage liver disease are the most common indications for liver transplantation (LTx) in our area. Recurrent HCV infection is universal after LTx and although histological recurrence is variable, the rate of disease progression is more rapid than in non-immunosuppressed patients and this impact graft and patient survival. All anti-HCV treatment strategies have shown limited efficacy so, at the present time, HCV reinfection after LTx represents the most important clinical problem in the follow-up. Regarding HBV, the most important factor in viral recurrence in the allograft is the presence of active viral replication at the time of LTx. The best patient selection (in non-replicative phase), the indefinite use of hyperimmune anti-hepatitis B immunoglobulin and the use of the new antiviral drugs have made possible a significant improvement in graft and patient survival.

Abstract
The use of livers from anti-hepatitis B core (HBc) positive donors can alleviate donor shortage. Nineteen of 367 (6%) adults receiving anti-HBc positive allografts [three were hepatitis B antigen (HBsAg) negative, hepatitis B antibody (HBsAb) positive; four were HBsAg positive and 12 were not exposed to hepatitis B viral (HBV) infection] were retrospectively reviewed. In HBsAg negative recipients, immunoprophylaxis (IP) was guided by viral serology and immunohistochemistry (IH) of day 0 and day 7 liver biopsies. If IH was negative, IP was stopped. None of three HBsAg negative, HBsAb positive recipients infected; one (replicating) of four HBsAg positive recipients reinfected and seven of eight (87.5%) HBsAg, HBsAb negative recipients, who did not receive long-term IP, infected after a median time of 2 years (range 1-5); one patient died of liver failure. Four HBsAg, HBsAb negative recipients, receiving life-long IP, remained infection free. Anti-HBc positive donor livers must be directed selectively first to HBsAg positive recipients, next to recipients having HBV antibodies and finally to HBV-naive recipients. Identification of both donor and recipient risk factors for HBV infection before transplantation allows indiscriminate use of antiviral prophylaxis. The necessity for IP therapy should be guided by HBV-DNA testing of donor liver tissue and serum. IH of early liver biopsies is an unreliable marker for predicting antiviral treatment requirements.

Abstract
The use of hepatitis B core antibody (HBcAb)- and hepatitis C virus antibody (HCV+) liver grafts for transplantation in selected populations has not affected patient and graft survival. We reexamined the clinical outcomes of using these HBcAb+ and HCV+ grafts at our institution, in addition to studying recipients of combined HBcAb+/HCV+ grafts. We identified 377 patients who underwent transplantation for either hepatitis B and/or hepatitis C, or received both HBcAb+ and HCV+ grafts. Patient and graft survival at 5 years posttransplantation was 73% and 71%, respectively, in the HBcAb+ grafts compared with 81% and 75% in the HBcAb- grafts (P =.65; P =.94). For HCV+ grafts, patient and graft survival at 5 years posttransplantation was 89% and 73%, respectively, compared with 69% and 59% in the HCV- grafts; (P =.22; P =.77). The 5-year patient and graft survival rate in those who received combined HBcAb+/HCV+ grafts was 74% and 69%, respectively, and there was no statistical difference compared with the HBcAb+ and HCV+ grafts (P =.76; P =.90). The 5-year patient and graft survival rate in patients who received dual HBV prophylaxis with hepatitis B immunoglobulin (HBIg) and lamivudine was 88% and 84%, respectively, which was significantly higher than for patients who received single prophylaxis or no prophylaxis (P <.01; P =.02). Our study supports previous observations that patient and graft survival is not affected with the use of HBcAb+ and HCV+ grafts, and that dual prophylaxis with HBIg and lamivudine offers substantial survival benefits. Furthermore, the use of combined HBcAb+/HCV+ grafts did not impact patient or graft survival. This provides a potential new pool of donor livers that can be used for transplantation in select patients.

Abstract
The enduring shortfall of organ donors has inspired the widespread utilization of hepatic allografts from donors with hepatitis B core antibodies in spite of the potential risk of transmitting hepatitis B virus (HBV) infection to the recipient. Here we report a protocol of naive recipients receiving livers from hepatitis B core antibody-positive donors. From November, 1999 to March, 2002, 77 liver transplantations were performed in 73 patients at our institution, 7 of whom received livers from hepatitis B core antibody-positive donors. All recipients received 10,000 U/d of intravenous HBIg for 7 days and 100 mg/d of lamivudine until we could obtain the HBV-DNA from the donor samples (serum and liver tissue). If the results of the HBV-DNA from the donor samples were positive, the patient would continue with prophylaxis and if they were negative we would finish the combined prophylaxis. After transplantation, HBV serologic markers and HBV-DNA by polymerase chain reaction (PCR) in serum and lymphocytes were tested in the recipients on the seventh, fifteenth, thirtieth, and ninetieth days as well as every 3 months after transplantation. All seven donor organs were negative for HBV-DNA in serum and liver tissue. Thus, we stopped the combined prophylaxis in all recipients (range, 7 to 10 days). None of the 7 patients developed de novo HBV infection over the 3-year study period (range, 9 to 36 months). Our approach is reasonably safe, and it appears to be very effective in the prevention of de novo HBV infection after liver transplantation.

Abstract
Chronic HBV infection is a common cause of advanced liver disease that is associated with substantial mortality. Furthermore, chronic hepatitis B was historically a controversial indication for liver transplantation because of a low post-transplant survival, with graft infection being the major contributor to adverse outcomes. The initial use of hepatitis B immune globulin as prophylaxis, followed later by combined therapy with lamivudine, markedly reduced viral recurrence and improved the survival of patients transplanted for acute or chronic hepatitis B with liver failure. Lamivudine alone can also be used for long-term prophylaxis against de novo HBV infection that can be transmitted by organs from donors positive for anti-HBc or anti-HBs. When used in patients with decompensated chronic hepatitis B with cirrhosis, lamivudine has been shown to improve clinical manifestations, prolong pretransplant survival, and defer, or even obviate, the need for transplantation. Despite prophylaxis, viral mutations with breakthrough reinfection may occur and lead to liver failure. The recently approved adefovir dipivoxil, which is active against lamivudine-resistant mutation, and other nucleoside analogs that are in various phases of development, offer hope as rescue therapy for viral recurrence. Other therapeutic alternatives in the future may include gene therapy and immune interventions.

Abstract
De novo hepatitis B virus (HBV) infection after orthotopic liver transplantation (OLT) in patients negative for hepatitis B surface antigen (HBsAg) is between 1.7% and 3.5% in areas with a low prevalence of HBV infection. The importance of this problem and the efficacy of lamivudine treatment has not been defined in areas with a high prevalence of positivity to antibody to hepatitis B core antigen (Anti-HBc). To define the characteristics and the clinical impact of de novo HBV infection in OLT recipients and to evaluate the efficacy of lamivudine treatment in this context, 229 HBsAg (-) donors (145 men, 84 women) were retrospectively evaluated between June 1994 and June 2000. Forty-eight recipients were excluded for various reasons. The final study population included 181 patients that were prospectively followed up for more than 6 months after OLT. When de novo HBV infection was detected, liver allograft biopsy was performed and treatment with lamivudine was indicated if patients were HBV-DNA-positive with elevated ALT levels. Survival time was defined as the interval between diagnosis of HBV infection and death or last follow-up visit. Thirty-one of 229 liver donors (13.5%) were anti-HBc(+). After a mean follow-up of 54.4+/-30 months, 9 of the 181 recipients (5%) developed de novo HBV infection; 8 of 27 recipients (29.6%) of livers from anti-HBc(+) donors as compared with only one of 154 recipients (0.6%) of livers from anti-HBc(-) donors P < 0.005). Liver biopsies performed in 8 of 9 cases showed chronic active hepatitis in 7 patients and acute hepatitis in one patient who cleared HBV spontaneously during the first 3 months. Seven patients were treated with lamivudine for a mean period of 24.5 months; HBV-DNA became negative in 5 of 7 (71.4%), and HBeAg became undetectable in 3 of 6 patients (50%). Patient actuarial survival rates at 1, 3, and 5 years were 100%, 94.7%, and 81.2% for recipients of anti-HBc (+) livers and 95.2%, 83%, and 77.3% for recipients of anti-HBc (-) livers P = ns). In our area, the appearance of de novo HBV infection after OLT is related to grafting livers from anti-HBc (+) donors is associated with a benign outcome, with no liver failure or graft loss, and treatment with lamivudine is highly effective in the control of HBV replication.

Abstract
BACKGROUND The present scarcity of organ donors requires consideration of grafts from sources not previously used. Several studies have addressed the use of grafts from donors who have antibodies to the hepatitis B core antigen (anti-HBc+). The aim of this study was to evaluate the impact of the use of anti-HBc+ grafts in patients transplanted for hepatitis B virus (HBV)-related cirrhosis. METHODS Recipients of first hepatic transplants from donors with antibodies to HBV were identified retrospectively. All patients who had serology suggestive of active HBV and were negative for hepatitis C and D were included in the analysis. The Kaplan-Meier method was used to assess the actuarial recurrence-free survival on patients with graft survival longer than 1.5 months. The stepwise Cox regression model was used to identify independent predictors of HBV recurrence. RESULTS One thousand seven hundred seventeen first liver transplants were performed at the Thomas E. Starzl Transplantation Institute from September 1, 1990, to December 31, 1999. HBV was the cause of cirrhosis in 112 patients (6.5%). Thirty-three patients had coexistent viral infection (23 HCV and 10 HDV). Fourteen donors (17.2%) were positive for HBV markers, with nine anti-HBc+ and with five both anti-HBc+ and anti-HB surface-positive; of these, 13 anti-HBc+ organ recipients had long-term survival. Nine (69.2%) of these cases were reinfected versus 20 (35.7%) in the group that received grafts from HBV- donors (P<0.05, Fisher's exact test). The mean time to reinfection was shorter in the anti-HBc+ group (2.9 yr vs. 6.4 yr, P<0.005). There were no statistical differences in graft or patient survival between the two groups. HBV prophylaxis with combined lamivudine and hepatitis B immunoglobulin (HBIG) significantly reduced the reinfection rate (P<0.03). Hepatitis Be (Hbe) antigen-positive recipients trended to faster reinfection (not significant). Cox regression analysis revealed that both anti-HBc graft donor status (RR, 2.796; P=0.020) and combination of lamivudine/HBIG (RR, 0.249; P=0.021) are independently associated with reinfection. CONCLUSIONS The use of anti-HBc+ liver grafts does not affect graft or patient survival. However, patients who receive these organs are 2.5 times more likely to develop HBV recurrence. Lamivudine and HBIG combination decreases HBV recurrence 4-fold.

Abstract
BACKGROUND Organ shortage continues to be a major problem in transplantation. The use of organs from marginal donors who are hepatitis B surface antigen (HBsAg) negative and hepatitis B core antibody (anti-HBc Ab) reactive (+), could increase the donor pool substantially. Little information is available about the effects of anti-HBc Ab (+) donor status on viral transmission, and graft and patient survival. To address these issues, an analysis was performed using the United Network of Organ Sharing cadaveric kidney transplant database between 1994 to 1999. METHODS All cadaveric kidney transplants performed between 1994 to 1999 with negative HBsAg serology were evaluated. Viral transmission, and graft and patient outcomes were measured. The analysis included follow-up information in the United Network of Organ Sharing database through September 2000. A multivariate analysis was performed, using known confounding factors that may affect the outcomes in donors and recipients who were designated as (+) or (-) (D+/R+, ++D+/R-, D-/R-, and D-/R+) according to their anti-HBc Ab status. RESULTS Univariate analyses showed that graft and patient survival rates were statistically significantly lower in D+/R- compared with those who were D-/R-. However, multivariate regression analyses showed that neither donor nor recipient anti-HBc Ab status influenced the risk of graft failure or patient death after adjustment for other factors. Anti-HBc Ab (+) kidneys resulted in a higher incidence of anti-HBc antibody seroconversion but this was not associated with a higher incidence of HBsAg detection. CONCLUSION We conclude that renal allografts from anti-HBc Ab (+) donors should be considered for transplant especially in successfully immunized recipients.

Abstract
Significant improvements in both patient and graft survival after orthotopic liver transplantation (OLT) for hepatitis B virus (HBV)-related liver failure have been made during the last decade. Recurrence of HBV infection has decreased, even in high-risk patients. Despite ongoing progress, challenges remain for the next millennium, including the determination of cost-effective dosing strategies, treatment of HBV infection in liver transplant recipients, and ramifications of the use of new antiviral agents, specifically, the appearance of resistant strains. This review summarizes the relevant history of OLT for chronic viral hepatitis B, details accepted preventive and therapeutic treatments, and discusses ongoing experimental trials. Emphasis also is placed on new approaches in transplantation as they impact on the care of HBV-infected patients.

Abstract
Donor shortage has led to the use of hepatitis B core antibody (anti-HBc)--positive (anti-HBc(+)) liver allografts for patients in need of relatively urgent orthotopic liver transplantation (OLT). Because anti-HBc(+) allografts transmit hepatitis B virus (HBV) infection at a high rate, effective prophylaxis is required. We assessed the effectiveness of lamivudine in preventing HBV transmission by anti-HBc(+) allografts. Between March 1996 and March 2000 at Cedars-Sinai Medical Center (Los Angeles, CA), 15 of 169 patients (8.9%) received liver allografts from anti-HBc(+) donors. Six patients were hepatitis B surface antigen (HBsAg)(+) (group 1), and 9 patients were HBsAg negative (HBsAg(-); group 2) before OLT. All patients were administered lamivudine, 100 or 150 mg/d, orally after OLT. Patients who were HBsAg(+) before OLT also were administered hepatitis B immunoglobulin (HBIG) prophylaxis. Hepatitis B serological tests were performed on all patients, and HBV DNA was determined in liver tissues in 10 patients. All 15 patients remained HBsAg(-) at their last follow-up 2 to 40 months (mean, 17 months) post-OLT. All patients in group 1 had antibody to HBsAg (anti-HBs) titers greater than 250 mIU/mL post-OLT (mean follow-up, 20 months; range, 7 to 40 months). Of the 2 patients in group 1 who underwent liver biopsy after OLT, 1 patient had detectable hepatic HBV DNA despite being anti-HBs(+) and HBsAg(-). Among the patients in group 2, none acquired anti-HBc or HBsAg. Hepatic HBV DNA was undetectable in the 7 patients in group 2 who underwent liver biopsy after OLT. Anti-HBc(+) allografts can be safely used in patients who undergo OLT for chronic hepatitis B and susceptible transplant recipients if prophylaxis with combination HBIG and lamivudine or lamividine alone is administered after OLT, respectively. However, more data are needed to determine the efficacy of lamivudine monotherapy in preventing transmission of HBV infection from anti-HBc(+) liver allografts to susceptible recipients.

Abstract
Liver transplantation has become the treatment of choice for patients with end-stage liver disease. De novo hepatitis B infection after liver transplantation is a rare event and usually runs a mild clinical and histological course. Despite the favourable outcome, a wide spectrum of hepatitis B virus (HBV)-associated liver disease may develop, ranging from asymptomatic carriage to severe chronic active hepatitis or cirrhosis and even fulminant hepatic failure. The achievement of protective titres of anti-HBs through vaccination has been suggested to be protective against the development of de novo HBV infection. The results of vaccination in cirrhotic patients awaiting for liver transplant have been very disappointing. High-dose/short-term schedules have been tried in transplant candidates in order to increase the response rate. New and more immunogenic formulations (containing new adjuvants or additional pre-S1/pre-S2 recombinant antigens), and, more importantly, early vaccination of potential transplant candidates at earlier stages of their liver disease should further prevent de novo hepatitis B in transplant recipients.
