Hepatitis B Virus Reactivation in Kidney Transplant Recipients Treated With Belatacept. Kidney Int Rep 2023; 8:1531-1541. [PMID: 37547512 PMCID: PMC10403656 DOI: 10.1016/j.ekir.2023.05.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Revised: 04/30/2023] [Accepted: 05/08/2023] [Indexed: 08/08/2023] Open
Abstract
Introduction Hepatitis B virus (HBV) reactivation in kidney transplant recipients has been reported in 3% to 9% of anti-HBc antibody (HBcAb)-positive HBs antigen (HBsAg)-negative patients. It has not been studied in patients receiving belatacept, a selective costimulation blocker. Methods We performed a retrospective study of all transplant recipients receiving belatacept in 2 kidney transplantation centers in France. Among HBcAb-positive patients, we analyzed HBV reactivation rate, outcomes, and risk factors. Results A total of 135 patients treated with belatacept were included: 32 were HBcAb-positive and 2 were HBsAg-positive. Seven patients reactivated HBV (21.9% of HBcAb-positive patients), including 5 HBsAg-negative patients (16.7% of HBcAb-positive HBsAg-negative patients). Reactivation occurred 54.8 (± 70.9) months after transplantation. One patient presented with severe hepatitis and 1 patient developed cirrhosis. There was no significant difference in survival between patients that reactivated HBV and patients that did not: 5-year patient survival of 100% (28.6; 100) and 83.4% (67.6; 100), respectively (P = 0.363); and 5-year graft survival of 100% (28.6; 100) and 79.8% (61.7; 100), respectively (P = 0.335). No factor, including HBsAb positivity and antiviral prophylaxis, was statistically associated with the risk of HBV reactivation. Conclusion HBV reactivation rate was high in patients treated with belatacept when compared with previous transplantation studies. HBV reactivation did not impact survival. Further studies are needed to confirm these results. A systematic antiviral prophylaxis for these patients should be considered and evaluated.

Abstract
Multiple sclerosis (MS) is a chronic inflammatory demyelinating disorder of the central nervous system. The immunopathology of MS involves both T and B lymphocytes. Rituximab is one of the anti-CD20 monoclonal antibody therapies which deplete B-cells. Although some anti-CD20 therapies have been approved by the Food and Drug Administration for treatment of MS, rituximab is used off-label. Several studies have shown that rituximab has a good efficacy and safety in MS, including certain specific patient conditions such as treatment-naïve patients, treatment-switching patients, and the Asian population. However, there are still questions about the optimal dose and duration of rituximab in MS due to the different dosing regimens used in each study. Moreover, many biosimilars have become available at a lower cost with comparable physicochemical properties, pharmacokinetics, pharmacodynamics, efficacy, safety, and immunogenicity. Thus, rituximab may be considered as a potential therapeutic option for patients without access to standard treatment. This narrative review summarized the evidence of both original and biosimilars of rituximab in MS treatment including pharmacokinetics, pharmacodynamics, clinical efficacy, safety, and dosing regimen.

Abstract
The prophylaxis strategy for hepatitis B virus (HBV) reactivation in kidney transplant recipients (KTRs) with resolved HBV infection remains unclear. In this hospital-based retrospective cohort study, consecutive KTRs with resolved HBV infection were screened from the years 2000 through 2020. After excluding confounding conditions, 212 and 45 patients were respectively recruited into Anti-HBs positive and Anti-HBs negative groups. Cumulative incidences of, and subdistribution hazard ratios (SHRs) for HBV reactivation were analyzed after adjusting the competing risk. During a median 8.3 (mean 8.4 ± 4.9) years of follow-up, the 10-year cumulative incidence of HBV reactivation was significantly higher in Anti-HBs negative group when compared to that in Anti-HBs positive group (15.2%, 95% CI: 3.6-26.7 vs. 1.3%, 95% CI: 0.0-3.0; p < 0.001). In multivariable regression analysis, absence of anti-HBs (SHR 14.2, 95% CI: 3.09-65.2; p < 0.001) and use of high-dose steroids, i.e., steroid dose ≥20 mg/day of prednisolone equivalent over 4 weeks (SHR 8.96, 95% CI: 1.05-76.2; p = 0.045) were independent risk factors related to HBV reactivation. Accordingly, the 10-year cumulative incidence of HBV reactivation occurring in patients with two, one and zero risk factors was 42.7% (95% CI: 0.0-87.1), 7.9% (95% CI: 1.2-14.7) and 0%, respectively (p < 0.001). In conclusion, the strategy of HBV antiviral prophylaxis may be defined according to the risk stratification.

Abstract
Purpose of Review We reviewed the current data on infections associated with rituximab use published over the last 5 years. Recent Findings New literature was available on rates of serious infections, Hepatitis B reactivation and screening, and infection with Severe Acute Respiratory Syndrome Coronavirus 2. Summary Rates of infection varied by study and population, however, higher risk of infection in patients with underlying rheumatologic diseases was seen in those who required a therapy switch, had a smoking history, and those undergoing retreatment who had a serious infection with their first course of therapy. With regards to HBV, the proportion of patients screened continues to be inadequate. Despite the upfront cost, HBV screening and prophylaxis were found to be cost effective. There is still limited data regarding COVID-19 severity in the setting of rituximab, however, rituximab, especially in combination with steroids, may lead to more severe disease and higher mortality.

Clinical significance of tacrolimus intra-patient variability on kidney transplant outcomes according to pre-transplant immunological risk. Sci Rep 2021; 11:12114.

Abstract
High intra-patient variability (IPV) of tacrolimus trough concentrations is increasingly recognized as a predictor of poor long-term outcomes in kidney transplant. However, there is a lack of information regarding the association between tacrolimus IPV and graft outcomes according to immunological risk. We analyzed tacrolimus IPV using the coefficient of variability from months 6-12 after transplantation in 1080 kidney transplant recipients. Patients were divided into two immunological risk groups based on pre-transplant panel reactive antibodies and donor-specific antibodies. High immunological risk was defined as panel reactive antibodies ≥ 20% or the presence of donor-specific antibodies. The effects of tacrolimus IPV on graft outcomes were significantly different between low and high immunological risk patients. A multivariable Cox regression model confirmed that high tacrolimus IPV was an independent risk factor for graft failure in the high risk group (HR, 2.90; 95% CI, 1.42-5.95, P = 0.004). In the high risk group, high tacrolimus IPV was also significantly associated with increased risk of antibody-mediated rejection (P = 0.006). In contrast, death-censored graft survival and antibody-mediated rejection in the low immunological risk group was not significantly different by tacrolimus IPV. High tacrolimus IPV significantly increases the risk of graft failure and antibody-mediated rejection in patients with high immunological risk.

Outcome after kidney transplantation in hepatitis B surface antigen-positive patients. Sci Rep 2021; 11:11744.

Abstract
Few reports detail the actual outcome of Hepatitis B Surface Antigen-positive patients after kidney transplant. HBsAg-positive patients who underwent kidney transplant between January, 1999, and December, 2018, were reviewed retrospectively. Outcomes including hepatitis B reactivation rate, risk factors for reactivation, and patient and graft survival rates were analyzed. Seventy-seven patients were enrolled (47.1 ± 11.5 years old). Patients received ABO-incompatible (n = 5), crossmatch positive transplant (n = 2), and re-transplant (n = 4). Forty-six patients received prophylactic; 19, medication at least 3 months before the transplant; and 12, did not receive medication. Seventeen out of 76 patients developed reactivation post-transplant. 52.9% of HBV reactivation was accompanied by hepatitis. Inappropriate, other than lifelong prophylactic, antiviral agents (HR = 7.34, 95% CI 1.51–35.69, P = 0.01) and high hepatitis DNA (≥ 1000 IU/ml) pre-transplant (HR = 4.39, 95% CI 1.08–17.81, P = 0.04) increased reactivation risk. There was no significant difference in patient and graft survival between antigen positive patients who received antiviral agent and propensity score matched negative patients. HBsAg positivity in kidney transplant recipients is associated with substantial HBV reactivation rate. Lifelong antiviral therapy is mandatory, and patients with high preop HBV titer should be monitored closely for HBV reactivation.

Abstract
Serum bilirubin, a potent endogenous antioxidant, has been associated with decreased risks of cardiovascular disease, diabetes, and kidney disease. However, the effects of serum bilirubin on kidney transplant outcomes remain undetermined. We analyzed 1628 patients who underwent kidney transplantations between 2003 and 2017. Patients were grouped into sex-specific quartiles according to mean serum bilirubin levels, 3–12 months post-transplantation. Median bilirubin levels were 0.66 mg/dL in males and 0.60 mg/dL in females. The intra-individual variability of serum bilirubin levels was low (9%). Serum bilirubin levels were inversely associated with graft loss, death-censored graft failure, and all-cause mortality, independent of renal function, donor status, and transplant characteristics. Multivariable analysis revealed that the lowest serum bilirubin quartile was associated with increased risk of graft loss (HR 2.64, 95% CI 1.67–4.18, P < 0.001), death-censored graft failure (HR 2.97, 95% CI 1.63–5.42, P < 0.001), and all-cause mortality (HR 2.07, 95% CI 1.01–4.22, P = 0.046). Patients with lower serum bilirubin were also at greater risk of rejection and exhibited consistently lower glomerular filtration rates than those with higher serum bilirubin. Serum bilirubin levels were significantly associated with transplantation outcomes, suggesting that bilirubin could represent a therapeutic target for improving long-term transplant outcomes.

Abstract
This 24-color flow cytometry panel focuses on characterizing antigen-specific B cells and precise delineation of B-cell subsets in chronic infections and is applicable to other chronic diseases such as autoimmunity. The panel was optimized for human cryopreserved peripheral blood mononuclear cells (PBMCs). Markers were chosen to extensively distinguish B-cell lineages (CD19, CD20, CD10, CD38, CD24, IgM, IgD, CD27, CD21, CD43, CD5). Inclusion of antigen-specific probes was of high priority in order to assess hepatitis B virus (HBV) antigen-specific B cells for our purposes. These probes can be readily exchanged for other pathogen-specific probes or additional markers for the panel to be tailored to desired research questions beyond HBV. In addition, we included a comprehensive and unique set of functional markers such as chemokine receptors (CXCR3, CXCR5), co-stimulatory molecule (CD86), Fc receptor (CD32), regulatory molecules (BTLA, CD39), and inhibitory markers associated with chronic infections (PD-1, FcRL5, CD11c, CD22) to enable in-depth analysis of global and antigen-specific B cells during chronic infection. © 2020 International Society for Advancement of Cytometry.

Abstract
Nowadays, intensive immunosuppressive therapy including rituximab is commonly used prior to kidney transplantation (KT), raising concerns over hepatitis B virus (HBV) reactivation among hepatitis B surface antigen (HBsAg)-negative and anti-hepatitis B core (HBc)-positive KT recipients. Recent practice guidelines suggested watchful monitoring or antiviral prophylaxis for the first 6-12 months, the period of maximal immunosuppression. However, the actual risk for HBV reactivation, and whether short-term antiviral therapy in the early period is necessary, remains unclear. A total of 449 HBsAg-negative and anti-HBc-positive KT recipients were analysed for HBV reactivation. During a median follow-up of 6.7 (interquartile range: 4.2-9.4) years, HBV reactivation was observed in 9 patients (2.0%). The median time of HBV reactivation from KT was 2.8 years (range: 1.4-11.5 years), with cumulative incidence rates of 0%, 1% and 2% for 1, 3 and 5 years, respectively. There were no severe adverse outcomes, including liver transplantation or mortality related to HBV reactivation. The risk of HBV reactivation was not high, even in anti-HBs-negative patients (n = 60, 4% at 5 years), ABO mismatch (n = 92, 4% at 5 years), use of rituximab (n = 66, 3% at 5 years) or plasmapheresis (n = 17, 7% at 5 years), and acute rejection (n = 169, 3% at 5 years). In conclusion, the HBV reactivation risk was not high and the time of detection was not clustered in the early post-KT period. Our findings favour continued watchful monitoring over antiviral prophylaxis in the early period.

Abstract
Sensitization to human leukocyte antigens (HLAs) has been one of the major clinical challenges for successful kidney transplantation. In end-stage renal disease, kidney transplantation provides benefits compared with dialysis in terms of improved patient survival better quality of life, and lower ongoing costs after the first year. Living donor kidney transplantation has an advantage with improved allograft survival, and performed earlier and electively compared with deceased donor transplantation. However sensitized patients are increasing in number on transplant waiting lists, and their prospect of getting a transplant is less than nonsensitized patients due to immunological incompatibility with the donor. Strategy for sensitized patients are listing for a compatible deceased donor transplant or, if they have a living donor, either selecting a kidney exchange program or undergoing a desensitization procedure. Desensitization procedures may be undertaken to increase access to either living or deceased donor transplants, and in some situations may also be employed to facilitate participation in a kidney exchange, in less immunological barrier to be overcome. The question of whether individuals are better off with a desensitization treatment followed by HLA-incompatible living donor transplantation or waiting on the deceased donor kidney transplant list for a compatible transplant has recently been addressed by two large multicenter studies, with conflicting results. A multicenter study from the United States published in the New England Journal of Medicine [365;318 326.2011] concluded that there was a strong survival benefit for sensitized patients undergoing desensitization followed by HLA-incompatible living donor kidney transplant compared with those remaining on the waiting list. Of interest, a second study, published in the Lancet, [389;727 734.2017] found no significant survival advantage for desensitized patients compared with similar patients remaining on the waiting list in the United Kingdom. Controversies still remain regarding how desensitization can be achieved and which techniques are effective and safe. In this chapter various complications from the desensitization will be dealt with in current use of medications or armamentum.

Abstract
We report a case of HBV reactivation following belatacept treatment in a patient who underwent kidney transplantation in 2015 for HIV-associated nephropathy (HIVAN). Human immunodeficiency virus viral load was undetectable prior to transplantation, and CD4+ lymphocyte count was greater than 300/mL. Baseline HBV serology at transplantation was HBsAg negative, anti-HBcAb positive, anti-HBsAb 312 UI/L, and HBeAg negative/anti-HBeAb positive. Liver function tests were normal, and viral DNA was undetectable. Two years later, the patient presented with severe acute hepatitis after a progressive disappearance of anti-HbsAb, quickly followed by HBV reactivation. Immunosuppressive treatment was drastically reduced, and treatment with entecavir was started. The outcome was favorable, and HBV DNA became undetectable after 9 weeks of treatment. This is the first report of acute hepatitis related to HBV reactivation in a kidney transplant recipient treated with belatacept. The risk for HBV reactivation in patients treated with belatacept should not be underestimated, especially in those with resolved HBV infection.

Presence of Hepatitis B Surface Antibody in Addition to Hepatitis B Core Antibody Confers Protection Against Hepatitis B Virus Infection in Hepatitis B Surface Antigen-negative Patients Undergoing Kidney Transplantation. Transplantation 2019; 102:1717-1723.

Abstract
BACKGROUND The American Gastroenterological Association and European Association for the Study of the Liver recommend that hepatitis B surface antigen (HBsAg)-negative and hepatitis B core antibody (anti-HBc)-positive patients who receive immunosuppression should be monitored for hepatitis B virus (HBV) infection regardless of hepatitis B surface antibody (anti-HBs) status. However, anti-HBs may provide protection against infection. To investigate whether the presence of anti-HBs in addition to anti-HBc confers protection, we classified HBsAg(-) kidney transplantation (KT) patients into 4 groups according to anti-HBc and anti-HBs status, and compared the HBV infection rate between the anti-HBc(+)anti-HBs(+) group and the other 3 groups. METHODS In this single-center retrospective study, we classified 1959 patients into 4 groups: anti-HBc(-)anti-HBs(-) (n = 356), anti-HBc(-)anti-HBs(+) (n = 652), anti-HBc(+)anti-HBs(-) (n = 142), and anti-HBc(+)anti-HBs(+) (n = 809). RESULTS Hepatitis B virus infection was noted in 31 (1.6%) patients after KT. There was a significant difference in HBV infection rate between anti-HBc(+)anti-HBs(+) (1.2%) and anti-HBc(+)anti-HBs(-) (5.6%) (P < 0.001), but not between anti-HBc(+)anti-HBs(+) and anti-HBc(-)anti-HBs(-) (1.1%) or anti-HBc(-)anti-HBs(+) (1.4%). There was a significant difference in HBV infection rate according to anti-HBs titer, but no difference according to the donor viral profile. Hepatic failure occurred in 1 anti-HBc(+)anti-HBs(-) patient and 1 anti-HBc(+)anti-HBs(+) patient, both of whom died. Hepatocellular carcinoma was noted in 4 anti-HBc(-) patients, but not in anti-HBc(+) patients. CONCLUSIONS The presence of anti-HBs confers protection against HBV infection. We recommend monitoring for HBV infection after KT in HBsAg(-) anti-HBc(+) anti-HBs(-) patients, but not in HBsAg(-) anti-HBc(+) anti-HBs(+) patients.

Risk of hepatitis B reactivation in hepatitis B surface antigen seronegative and core antibody seropositive kidney transplant recipients. Transpl Infect Dis 2018; 21:e13009.

Abstract
BACKGROUND Previous contact with Hepatitis B virus (HBV) is common in patients undergoing hemodialysis. Literature has shown conflicting results on the risk of HBV reactivation in kidney transplant (KT) recipients with serologic evidence of past HBV infection. METHODS We reviewed 631 consecutive KT recipients and selected 70 patients simultaneously HBsAg negative and anti-HBc positive before KT, regardless of hepatitis B surface antibody (anti-HBs) status. Demographic characteristics, coinfection with other viruses, the presence of a previous KT, induction and maintenance immunosuppression, length of follow up, biopsy-proven acute rejection episodes, incidence of impaired liver function, and causes of graft loss and mortality were collected. Hepatitis B virus reactivation was defined as detection of HBV DNA viral load >2000 IU/mL during follow up. Outcome data included HBV reactivation episodes, graft function, and patient survival. RESULTS Median follow-up was 151 months; 91.4% of patients were positive to anti-HBs prior to KT. No patient received HBV prophylaxis and 11 patients (15.7%) received rituximab as part of induction therapy. Anti-HBs titers remained stable in all patients throughout the observation period but two patient showed evidence of HBV reactivation after KT. CONCLUSION Hepatitis B virus reactivation in HBsAg-negative and anti-HBc-positive after KT is rare but possible. We suggest evaluating HBV serologies, HBV DNA viral load, and liver enzymes before KT and routinely monitoring serologic HBV markers after KT. As only two patients experienced HBV reactivation, it is neither possible to define risk factors for HBV reactivation nor to evaluate the impact of different immunosuppressants or the benefit of prophylactic regimens. Further studies regarding HBV reactivation in solid organ transplant recipients are necessary.

Abstract
Sensitized patients received desensitization therapy with rituximab for kidney transplantation. However, the impact of rituximab dose on hepatitis B virus (HBV) reactivation is unknown. Patients who underwent living donor kidney transplantation between 2008 and 2016 were grouped according to rituximab dose (control vs. standard-dose rituximab [375 mg/m2] vs. reduced-dose rituximab [200 mg/body]) for comparison of HBV reactivation. A total of 336 hepatitis B surface antigen (HBsAg)-negative/antibody to hepatitis B core antigen (anti-HBc)-positive patients underwent kidney transplantation, of whom 91 (27.1%) received rituximab for desensitization (57 standard-dose and 34 reduced-dose rituximab). During the study period, eight patients experienced HBV reactivation (three in the control group, five in the standard-dose group). In the standard-dose group, four patients experienced hepatitis flare, and one patient died due to hepatic failure. No HBV reactivation occurred in the reduced-dose group. Standard-dose rituximab significantly decreased hepatitis B surface antigen antibody titer (anti-HBs; −99.8 IU/L) at 12 months, compared with reduced-dose rituximab (−20.1 IU/L) and control (−39.1 IU/L, P = 0.017). Standard-dose rituximab (HR, 10.60; 95% CI, 2.52–44.60; P = 0.001) and anti-HBs < 100 IU/L at transplantation (HR, 9.06; 95% CI, 1.11–74.30; P = 0.04) were independent risk factors for HBV reactivation. Standard-dose rituximab significantly increased HBV reactivation risk for HBsAg-negative/anti-HBc-positive kidney transplant patients.

Abstract
Chronic HBV (CHB) infection suppresses virus-specific T cells, but its impact on humoral immunity has been poorly analyzed. Here, we developed a dual-staining method that utilizes hepatitis B virus (HBV) surface antigens (HBsAg) labeled with fluorochromes as "baits" for specific ex vivo detection of HBsAg-specific B cells and analysis of their quantity, function, and phenotype. We studied healthy vaccinated subjects (n = 18) and patients with resolved (n = 21), acute (n = 11), or chronic (n = 96) HBV infection and observed that frequencies of circulating HBsAg-specific B cells were independent of HBV infection status. In contrast, the presence of serum HBsAg affected function and phenotype of HBsAg-specific B cells that were unable to mature in vitro into Ab-secreting cells and displayed an increased expression of markers linked to hyperactivation (CD21lo) and exhaustion (PD-1). Importantly, B cell alterations were not limited to HBsAg-specific B cells, but affected the global B cell population. HBsAg-specific B cell maturation could be partially restored by a method involving the combination of the cytokines IL-2 and IL-21 and CD40L-expressing feeder cells and was further boosted by the addition of anti-PD-1 Abs. In conclusion, HBV infection has a marked impact on global and HBV-specific humoral immunity, yet HBsAg-specific B cells are amenable to a partial rescue by B cell-maturing cytokines and PD-1 blockade.

Abstract
OBJECTIVE To describe and quantify the incidence and morbidity of hepatitis B reactivation (HBVr) secondary to pharmaceutical agents (eg, rituximab, tumor necrosis factor inhibitors, direct-acting antivirals [DAAs] for hepatitis C) among patients with previously resolved hepatitis B infection. DATA SOURCES The MEDLINE database was searched from inception through July 2018 using the terms hepatitis B + ( reactivation OR [drug or drug class linked to HBVr]). STUDY SELECTION AND DATA EXTRACTION Relevant English-language cohort studies or randomized trials quantifying the incidence of HBVr secondary to pharmacotherapy among patients negative for hepatitis B surface antigen and DNA and positive for hepatitis B core antibody were included. DATA SYNTHESIS Among 2045 articles, 102 met inclusion criteria. Receipt of rituximab was associated with the highest risk of HBVr (for oncological indication: 6.2% rate [225/3601 patients]) and subsequent hepatitis (up to 52.4% of all HBVr cases). Biologic agents for autoimmune disease were uncommonly associated with HBVr (2.4%, 56/2338), with only 4 cases of hepatitis, all attributable to rituximab. Reactivation caused by DAAs was rare (0.3%, 28/8398), with no cases of hepatitis. Relevance to Patient Care/Clinical Practice: This review compares and contrasts the incidence and clinical relevance of HBVr for various pharmacotherapies among patients with functionally cured hepatitis B, with discussion of appropriate risk mitigation strategies. CONCLUSIONS Among patients with prior functional cure of hepatitis B, prophylactic antiviral therapy is recommended with rituximab administration irrespective of indication because of a high risk for HBVr-associated morbidity. Enhanced monitoring alone is reasonable for patients receiving nonrituximab biologics or DAAs.

Abstract
AIM To assess outcomes of kidney transplantation including patient and allograft outcomes in recipients with hepatitis B virus (HBV) infection, and the trends of patient's outcomes overtime. METHODS A literature search was conducted using MEDLINE, EMBASE and Cochrane Database from inception through October 2017. Studies that reported odds ratios (OR) of mortality or renal allograft failure after kidney transplantation in patients with HBV [defined as hepatitis B surface antigen (HBsAg) positive] were included. The comparison group consisted of HBsAg-negative kidney transplant recipients. Effect estimates from the individual study were extracted and combined using random-effect, generic inverse variance method of DerSimonian and Laird. The protocol for this meta-analysis is registered with PROSPERO (International Prospective Register of Systematic Reviews; no. CRD42017080657). RESULTS Ten observational studies with a total of 87623 kidney transplant patients were enrolled. Compared to HBsAg-negative recipients, HBsAg-positive status was significantly associated with increased risk of mortality after kidney transplantation (pooled OR = 2.48; 95%CI: 1.61-3.83). Meta-regression showed significant negative correlations between mortality risk after kidney transplantation in HBsAg-positive recipients and year of study (slopes = -0.062, P = 0.001). HBsAg-positive status was also associated with increased risk of renal allograft failure with pooled OR of 1.46 (95%CI: 1.08-1.96). There was also a significant negative correlation between year of study and risk of allograft failure (slopes = -0.018, P = 0.002). These associations existed in overall analysis as well as in limited cohort of hepatitis C virus-negative patients. We found no publication bias as assessed by the funnel plots and Egger's regression asymmetry test with P = 0.18 and 0.13 for the risks of mortality and allograft failure after kidney transplantation in HBsAg-positive recipients, respectively. CONCLUSION Among kidney transplant patients, there are significant associations between HBsAg-positive status and poor outcomes including mortality and allograft failure. However, there are potential improvements in patient and graft survivals in HBsAg-positive recipients overtime.

Abstract
Hepatitis B core antibody (anti-HBc) is considered the most sensitive serological marker for history of hepatitis B virus (HBV) infection. In a subset of anti-HBc carriers, anti-HBc is present in the absence of hepatitis B surface antigen and hepatitis B surface antibody-a serological pattern known as "isolated anti-HBc" (IAHBc). IAHBc has been of clinical interest over the past several years, with growing data to suggest its role as a serological marker for occult HBV infection (OBI). This article reviews the clinical significance and association of IAHBc with hepatitis C virus (HCV) co-infection, risk of HBV reactivation during direct-acting antiviral therapy for HCV as well as immune suppression, and development of hepatocellular carcinoma (HCC). Hepatitis B core-related antigen is also highlighted as an emerging laboratory assay that may identify OBI and predict HCC development in non-cirrhotic patients receiving nucleoside/nucleotide analog therapy.

Abstract
Selective depletion of CD20+ B cells by anti-CD20 monoclonal antibodies as monotherapy in multiple sclerosis (MS) profoundly suppresses acute inflammatory disease activity and signifies an important advance in the treatment of relapsing-remitting MS. Ocrelizumab, a humanized anti-CD20 monoclonal antibody, is also the first proven therapy to lessen disability progression in primary progressive MS-a breakthrough for patients with a disease that had no proven therapy. Ocrelizumab is generally well tolerated, with the most common adverse events experienced being infusion reactions and infections. In ocrelizumab trials in MS a numerical imbalance in the risk of malignancies was observed. In this article, we review advances in anti-CD20 B-cell-depleting biological therapies for MS, including ocrelizumab, rituximab, and ofatumumab.
