Abstract
Rheumatoid arthritis (RA) is an autoimmune disease characterized by proliferative synovitis, which can cause cartilage and bone damage as well as functional limitations. Disease-modifying anti-rheumatic drugs have significantly improved the prognosis of RA patients. However, people with RA, when combined with hepatitis B virus (HBV) infection, may experience reactivation of HBV during treatment with anti-rheumatic drugs. The outcome of HBV reactivation (HBVr) varies from liver inflammation to liver failure, while insufficient HBV screening in RA patients has been reported in various countries. Therefore, it is necessary to identify patients at high risk before starting immunosuppressive therapy. The immune response plays an important role in anti-HBV infection. However, most anti-rheumatic drugs exert an inhibitory effect on the body’s immune system, resulting in HBVr. Therefore, it is necessary to conduct a comprehensive evaluation based on host factors, viral factors, and drug factors. In this paper, we summarize the mechanism of HBVr, the risk of HBVr caused by anti-rheumatic drugs, and the appropriate diagnosis and treatment process for RA patients so that clinicians can have a more comprehensive understanding of HBVr in RA patients.

Abstract
Acute hepatitis B virus (HBV) infection occasionally progresses to acute liver failure, often with poor prognosis. The appropriate pharmacological approach is yet to be established. Although nucleotide analogs (NA) and corticosteroids are candidates for the treatment of acute HBV infection, their therapeutic effects, especially their effect on HBV clearance, remain unclear. To clarify effects on the HBV clearance of combination therapy of NA and steroid pulse therapy (SPT) for acute HBV infection, we first analyze the effectiveness of this therapy in patients with HBV infection compared with NA monotherapy (NAM). Of the 57 consecutive patients with acute hepatitis B infection from May 2007 to December 2018, we have included 25 patients for this study, whom we followed up until HBV clearance. According to the administration of NA and SPT, we divided patients into two groups (NAM group and NA + SPT group) and compared their results. Of the 25 patients, 10 received NAM, whereas 15 received NA + SPT. There were no appreciable adverse effects related to SPT. The time required for the clearance of HBsAg (76 (43–116) days vs. 26 (14–51) days, p = 0.0418) and HBV-DNA (NAM group vs. NA + SPT group: 180 (83.5–220) vs. 69 (43–136) days, p = 0.0420) was significantly shorter in the NA + SPT group than in the NAM group. The hazard ratio of NA + SPT for the clearance of HBsAg and HBV-DNA were 0.45 (0.19–1.09) and 0.35 (0.14–0.89), respectively. In conclusion, we showed that NA + SPT promoted HBV elimination. These findings support the use of the NA + SPT combination for acute HBV infection without the concern of persistent HBV infection.

Abstract
INTRODUCTION Immunosuppressive therapy for uveitis may cause liver damage. METHODS To investigate incidence of liver damage during uveitis treatment, we compared serological Hepatitis B core antibody (HBcAb) status with risk of liver dysfunction in all participants (n=992), in anterior uveitis (AU) (n=489) and combined of intermediate, posterior or panuveitis patients (IPPU) (n=503). The primary endpoint was incidence of elevated serum ALT level above two-fold upper limits of normal (ULN) within 6 months. RESULTS The incidence rate of primary endpoint for HBcAb negative and positive patients was 65 and 212 per 1,000 person years, respectively. The absolute rate difference was 147 (95% CI, 80-213) per 1,000 person years. HBcAb positivity was associated with a higher risk for primary endpoint in all participants (aHR, 3.53; 95% CI, 1.79-6.99; P value = 2.8×10-4) and in IPPU (aHR, 3.80; 95% CI, 1.61-9.01; P value = 0.002). No significant association with primary endpoint was observed for HBcAb positivity in AU (aHR, 3.21; 95% CI, 0.94-10.95; P value = 0.063). AU was mainly treated with topical eye drops (74.0%) whereas IPPU cases received systemic therapy including prednisone (94.0%), cyclosporine (80.9%) or other additionally combined immunomodulatory agents (14.9%). CONCLUSION Non-infectious uveitis cases with HBcAb positivity have an increased risk of liver damage. This association was predominantly driven by IPPU but was not significant in AU suggesting that the association is mediated by systemic therapy.

Abstract
Heat shock proteins (HSPs) are a large group of chaperones found in most eukaryotes and bacteria. They are responsible for the correct protein folding, protection of the cell against stressors, presenting immune and inflammatory cytokines; furthermore, they are important factors in regulating cell differentiation, survival and death. Although the biological function of HSPs is to maintain cell homeostasis, some of them can be used by viruses both to fold their proteins and increase the chances of survival in unfavorable host conditions. Folding viral proteins as well as replicating many different viruses are carried out by, among others, proteins from the HSP70 and HSP90 families. In some cases, the HSP70 family proteins directly interact with viral polymerase to enhance viral replication or they can facilitate the formation of a viral replication complex and/or maintain the stability of complex proteins. It is known that HSP90 is important for the expression of viral genes at both the transcriptional and the translational levels. Both of these HSPs can form a complex with HSP90 and, consequently, facilitate the entry of the virus into the cell. Current studies have shown the biological significance of HSPs in the course of infection SARS-CoV-2. A comprehensive understanding of chaperone use during viral infection will provide new insight into viral replication mechanisms and therapeutic potential. The aim of this study is to describe the molecular basis of HSP70 and HSP90 participation in some viral infections and the potential use of these proteins in antiviral therapy.

Abstract
HBV reactivation (HBVr) can occur in hepatitis B surface antigen (HBsAg)-positive and negative patients. Here, we determined the incidence of HBVr and its related hepatitis in patients with systemic lupus erythematosus (SLE). From 2000 to 2017, 3307 SLE cases were retrospectively reviewed for episodes of hepatitis. The incidence, long-term outcomes and risk factors associated with HBVr, including HBsAg reverse seroconversion (RS) were analyzed. Among them, 607 had available HBsAg status. Fifty-five (9.1%) patients were positive for HBsAg and 63 (11.4%) were HBsAg-negative/antibody to hepatitis B core antigen (anti-HBc)-positive (resolved hepatitis B infection, RHB). None of them received antiviral prophylaxis before immunosuppressive treatment. During a mean 15.4 years of follow-up, 30 (54.5%) HBsAg-positive patients developed HBVr and seven (23.3%) died of liver failure, whereas only two (3.2%) RHB cases experienced HBsAg reverse seroconversion (RS). Multivariate logistic regression analysis showed that age ≥ 40 years at diagnosis of SLE (HR 5.30, p < 0.001), receiving glucocorticoid-containing immunosuppressive therapy (HR 4.78, p = 0.003), and receiving glucocorticoid ≥ 10 mg prednisolone equivalents (HR 3.68, p = 0.003) were independent risk factors for HBVr in HBsAg-positive patients. Peak level of total bilirubin ≥ 5 mg/dL during HBVr was an independent factor of mortality (p = 0.002). In conclusion, the risk of HBVr was associated with glucocorticoid daily dose. Antiviral prophylaxis is mandatory for SLE patients diagnosed at age of ≥40 years who receive ≥ 10 mg daily dose of oral prednisone or equivalent.

Abstract
Objectives The aim of this retrospective analysis was to assess the incidence of hepatitis B virus (HBV) reactivation among patients with myeloproliferative neoplasms (MPN) during and after ruxolitinib treatment. Methods Between February 2013 and February 2020, 224 patients with MPN were treated using ruxolitinib at Peking Union Medical College Hospital. Of these, 6 had chronic, and 56 had resolved HBV infection, including 43 patients who received combination treatment with thalidomide, prednisone, and stanozolol (TSP) during ruxolitinib treatment. Results Two patients with chronic HBV infection who did not take any antiviral prophylaxis developed HBV reactivation and hepatitis flare. The other four patients with chronic HBV infection, who took antiviral prophylaxis before ruxolitinib treatment, did not develop HBV reactivation. Also, no patients with resolved HBV infection received antiviral prophylaxis and developed HBV reactivation. Conclusion This study demonstrated that HBV reactivation and hepatitis flare might commonly occur a few months after initiating ruxolitinib treatment in patients with chronic HBV infection who did not take antiviral prophylaxis, especially in combination with TSP. Still, it was extremely rare in patients with resolved HBV infection.

Abstract
BACKGROUND & AIMS In patients who have resolved hepatitis B virus (HBV) infection, treatment of rheumatoid arthritis (RA) can result in reappearance of hepatitis B surface antigen (HBsAg), called reverse seroconversion. We investigated clinical features and outcomes of reverse seroconversion in patients who received immunosuppressant or biologic therapy for RA. METHODS We identified 1494 patients with RA (925 who resolved HBV infection) and available data on levels of antibody to HB core antigen and HBsAg who had attended Taipei Veterans General Hospital from January 2007 through December 2017. We identified 17 cases (median age, 66 years) who were negative for HBsAg before treatment of RA and reverse seroconversion (HBsAg reappearance) after glucocorticoid treatment (n = 13) and/or biologic therapy (adalimumab, n = 2; etanercept, n = 1; rituximab, n = 9; or abatacept, n = 4). Four patients were positive for antibodies against HBsAg (seroconverted) before the immunosuppressive treatment. RESULTS The median time from immunosuppressive treatment to reverse seroconversion was 120 months (range, 20-264 months), whereas the time from biologic therapy treatment to reverse seroconversion was 66 months (range, 10-105 months). After reverse seroconversion, 8 individuals (47.1%) were positive for HB e antigen; 9 cases (52.9%) did not have a flare of alanine transaminase. However, 3 patients (17.6%) developed liver decompensation. CONCLUSIONS In patients who resolved HBV infection and received immunosuppressant treatment of RA, risk of reversal of seroconversion is low but persists for up to 10 years. Patients with RA who previously resolved HBV infections should be monitored for levels of HBsAg and HBV DNA once immunosuppressive treatment of RA begins.

Abstract
Stress proteins (SPs) including heat-shock proteins (HSPs), RNA chaperones, and ER associated stress proteins are molecular chaperones essential for cellular homeostasis. The major functions of HSPs include chaperoning misfolded or unfolded polypeptides, protecting cells from toxic stress, and presenting immune and inflammatory cytokines. Regarded as a double-edged sword, HSPs also cooperate with numerous viruses and cancer cells to promote their survival. RNA chaperones are a group of heterogeneous nuclear ribonucleoproteins (hnRNPs), which are essential factors for manipulating both the functions and metabolisms of pre-mRNAs/hnRNAs transcribed by RNA polymerase II. hnRNPs involve in a large number of cellular processes, including chromatin remodelling, transcription regulation, RNP assembly and stabilization, RNA export, virus replication, histone-like nucleoid structuring, and even intracellular immunity. Dysregulation of stress proteins is associated with many human diseases including human cancer, cardiovascular diseases, neurodegenerative diseases (e.g., Parkinson’s diseases, Alzheimer disease), stroke and infectious diseases. In this review, we summarized the biologic function of stress proteins, and current progress on their mechanisms related to virus reproduction and diseases caused by virus infections. As SPs also attract a great interest as potential antiviral targets (e.g., COVID-19), we also discuss the present progress and challenges in this area of HSP-based drug development, as well as with compounds already under clinical evaluation.

Abstract
Objective We started an information technology (IT) system that encodes the medical treatment status of hepatitis B virrus (HBV) with a 9-digit number, automatically checks for inappropriate situations occurring due to immunosuppression and chemotherapy that do not comply with the flowchart of the hepatitis B countermeasure guideline, and promotes correct HBV medical treatment in our hospital. We conducted a prospective study of HBV reactivation using this system. Methods Among 21,607 cases that were managed using this system, 1,206 patients who were HBs antigen-negative, HBc antibody- and/or HBs antibody-positive and in whom HBV DNA quantification was performed two times or more were examined for the occurrence of HBV reactivation. The study population included: malignant lymphoma patients using rituximab (n=40), patients with malignant tumors using anticancer agents (n=546), patients treated with steroids (n=274), rheumatoid arthritis (RA) patients (n=144), patients using immunosuppressants/biologics (n=26), and patients undergoing hepatitis C direct acting antiviral (DAA) treatment (n=176). Results HBV reactivation was observed in 27 cases undergoing treatment with the following agents: rituximab (n=6), anticancer agents (n=8), steroids (n=10), anti-RA agents (n=1), and hepatitis C DAA (n=2). Among the 40 patients who were using rituximab, 6 (18.2%) showed a high rate of reactivation. In 10 in which HBV reactivation occurred at a median of 10 (range, 4-32) months after steroid administration, 6 occurred after the 7th month, and 1 patient showed HBs antigen positivity and severe hepatitis. Conclusion Continuing of the operation of an automatic check system using coded medical information to check for the reactivation enabled this prospective study of HBV reactivation. Careful attention should be paid to patients using steroids, as well as malignant lymphoma patients who are treated with rituximab. The results of the present study suggest that the present IT encoding system would be useful for preventing HBV reactivation.

Abstract
Considered more efficacious and safer than traditional systemic drugs, biologic therapies have dramatically improved the quality of life of patients with psoriasis. Recently, there has been a proliferation of new targeted treatment options, including anti-interleukin-17, anti-interleukin-12/23, as well as small-molecule drugs such as apremilast. There are nevertheless some concerns regarding their use, especially in patients with chronic infections such as hepatitis B virus (HBV) and hepatitis C virus (HCV). It has been estimated that two billion individuals are infected with HBV worldwide and approximately 240 million have chronic HBV infection. Moreover, there are approximately 71 million individuals with chronic HCV infection worldwide, with a high percentage of them unaware of being infected. As patients with HBV and HCV infections are excluded from controlled clinical trials investigating new drugs, data regarding their safety in patients with psoriasis are based almost exclusively on case reports and small retrospective cohort studies and need to be constantly updated. The risk of HBV reactivation can be defined as: high risk (≥ 10%), moderate risk (1-10%), and low risk (< 1%) depending on the type of immunosuppressive therapy stratified by the presence or absence of hepatitis B surface antigen but positivity to anti-hepatitis B core antigen. Hepatitis B surface antigen-positive patients treated with tumor necrosis factor-α inhibitors, ustekinumab, or cyclosporine carry a high or moderate risk of HBV reactivation and should be considered candidates for prophylactic anti-HBV therapy. Once therapy is commenced, it is important to check HBV DNA levels every 3 months. Hepatitis B virus reactivation typically occurs with immune reconstitution and therefore antiviral therapy should continue for 6-12 months after stopping immunosuppression. Hepatitis B surface antigen-positive patients who are prescribed methotrexate, acitretin, or apremilast have a low risk and need to be monitored for viral reactivation by determining alanine aminotransferase and HBV DNA levels every 3 months. No conclusive data are available for interleukin-17 and interleukin-23 inhibitors. Anti-hepatitis B core antigen-positive patients treated with tumor necrosis factor-α inhibitors, ustekinumab, and cyclosporine are linked to a moderate risk of reactivation, and they should preferably undergo HBV DNA or hepatitis B surface antigen and alanine aminotransferase testing rather than be subjected to routine pre-emptive therapy. Anti-hepatitis B core antigen-positive patients receiving methotrexate, acitretin, or apremilast have a low risk of reactivation and do not require anti-HBV therapy, nor should monitoring be considered mandatory. No conclusive data are available for interleukin-17 and interleukin-23 inhibitors.

Abstract
OBJECTIVE Whether or not reactivation of hepatitis B virus (HBV) might occur during corticosteroid therapy in hepatitis B surface antigen (HBsAg)-negative patients with adrenal insufficiency was investigated. PATIENTS AND METHODS We consecutively enrolled 66 patients with adrenal insufficiency undergoing physiological corticosteroid replacement therapy at Saitama Medical University Hospital between June 2013 and June 2014, and 220 patients with rheumatic disease receiving a pharmacologic dose of corticosteroids served as the positive control group. The latter group was separated into 101 patients treated only with corticosteroids, and 119 patients given corticosteroids plus immunosuppressants and/or disease-modifying antirheumatic drugs (DMARDs). HBsAg and antibody (Ab) levels against HBs, and hepatitis B core (HBc) were determined in all the patients. In patients with positive HBsAb and/or HBcAb, real-time PCR was performed for HBV-DNA. The incidence rates of conversion to HBV-DNA-positive status were evaluated. RESULTS Hepatitis B virus reactivation occurred in six patients with rheumatic disease, three of whom were receiving a pharmacological dose of corticosteroids only, and three who were receiving corticosteroids with immunosuppressants and/or DMARDs. However, no reactivation occurred in patients receiving corticosteroid replacements for adrenal insufficiency. Maintenance and maximum corticosteroid doses administered to patients with rheumatic disease were significantly greater than those in patients with adrenal insufficiency. CONCLUSION These results suggest that, although corticosteroid replacement therapy for adrenal insufficiency might be safe with respect to HBV reactivation, attention should be paid to HBV reactivation during corticosteroid therapy in rheumatic disease patients, since the dose of corticosteroids administered is usually large, and since other immunosuppressants are co-administered.

Abstract
BACKGROUND Reports of hepatitis B virus (HBV) reactivation in solid tumors are very limited, and their frequencies and risk factors were previously unknown. AIM To evaluate the prevalence and risk factors of HBV reactivation in patients with solid tumors with resolved HBV infection. METHODS All 1088 patients with solid tumors were assessed for eligibility; 251 patients had resolved HBV infection (negative for HBs antigen and positive for anti-HBc antibody and/or positive for anti-HBs antibody), and HBV-DNA was assessed for 243 of these patients in whom we analyzed the prevalence of HBV reactivation. Risk factors for HBV reactivation were exploratorily evaluated by analysis of a case-control study. RESULTS The prevalence of HBV-DNA reactivation was 2.1% (95% confidence interval [CI], 0.3-3.9%). We did not observe any exacerbation of HBV-DNA by early intervention. A low anti-HBs antibody titer (<10.0 mIU/mL) and high average daily dexamethasone dose (>1.0 mg/day) were high risk factors, with odds ratios of 5.94 (95% CI, 1.15-30.6, P = 0.03) and 8.69 (95% CI, 1.27-58.8, P = 0.02), respectively. CONCLUSION HBV reactivation in solid tumor patients was relatively rare. Therefore, risk factors that can identify targets for HBV screening must be determined in future studies.

Abstract
This study aimed to determine the incidence and risk factors for hepatitis B virus (HBV) reactivation in patients with rheumatoid arthritis (RA) undergoing immunosuppressive therapy. The National Database of Japan, in which insurance claim data have been comprehensively accumulated, was utilized. The subjects were 76 641 RA patients who were plausibly initiated on immunosuppressive therapy from April 2013 to March 2014. Laboratory tests of the hepatitis B surface antigen, anti-hepatitis B virus surface antibody, and anti-hepatitis B virus core antibody were performed in 28.23%, 12.52% and 14.63% of patients, respectively, when the therapy was initiated. We found that HBV reactivation and fulminant hepatitis occurred in both the patients with and without HBV DNA monitoring, indicating insufficient monitoring in Japan during the study. The cumulative incidence of HBV reactivation over 24 months was 1.57% (95% confidence interval [CI] = 1.28%-1.92%) in the monitoring group, which consisted of those with resolved HBV infection. Glucocorticoid administration was a potent risk factor for HBV reactivation (hazard ratio [HR] = 1.70, 95% CI = 1.26-2.29, P = .001 in all subjects, and HR = 1.82, 95% CI = 1.18-2.81, P = .007 in the nonmonitoring group), although it was not statistically significant in the monitoring group (HR = 1.49, 95% CI = 0.99-2.26 and P = .057). No significant risk difference was observed between single administration of methotrexate and biological drugs.

Abstract
Background Reactivation of hepatitis B virus (HBV) is a fatal complication of chemotherapy. Occult HBV infection might be reactivated in patients undergoing chemotherapy or immunosuppression. However, the mechanism of HBV reactivation induced by chemotherapy or immunosuppression remains unclear. Material/Methods HepG2.2.15 cells were treated with an autophagy inducer (rapamycin), an inhibitor (3-methyladenine, 3-MA), and dexamethasone. Autophagosomes were observed by a transmission electron microscope (TEM). LC3-I, LC3-II, and P62 were analyzed by western blot. HBV replicative intermediates were detected by southern blot. HBV DNA expression was quantitated with real-time polymerase chain reaction (PCR). The level of HBV surface antigen (HBsAg) in culture medium was examined by ELISA. Results In this study, we find that dexamethasone stimulates HBV replication and protein expression by inducing autophagy in HepG2.2.15 cells. In contrast, autophagy inhibitor (3-MA) abrogates HBsAg secretion stimulated by dexamethasone. Conclusions Our results suggest that dexamethasone stimulates HBV replication through autophagy. This might provide a novel insight into the mechanism of glucocorticoid-mediated HBV reactivation through autophagy, which might be a new therapeutic target.

Abstract
We conducted data mining using the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) database on spontaneously reported adverse events to evaluate the association between anticancer drug therapy and hepatitis B infection. Reports of hepatitis B infection were retrieved from the FAERS database. The reporting odds ratio (ROR) was used to estimate the association between hepatitis B infection and various anticancer agents and drug combinations. We detected statistically significant risk signals of hepatitis B for 33 of 64 anticancer agents by ROR (26 cytotoxicity drugs and seven molecular-targeted drugs). We focused on molecular-targeted drugs and assessed the risk of hepatitis B from specific anticancer drug combinations. The frequency of hepatitis B infection was significantly high for drugs such as rituximab, bortezomib, imatinib, and everolimus. The addition of cyclophosphamide, doxorubicin, and fludarabine to drug combinations additively enhanced the frequency of hepatitis B infection. There were no reports on hepatitis B infection associated with trastuzumab or azacitidine monotherapy. However, trastuzumab-containing regimens (e.g., combinations with docetaxel or paclitaxel) were correlated with the incidence of hepatitis B infection, similar to azacitidine monotherapy. Our findings suggest that the concomitant use of anticancer drugs, such as trastuzumab, taxane, and azacitidine, may contribute to the risk of hepatitis B infection. The unique signals detected from the public database might provide clues to eliminate the threat of HBV in oncology.

Abstract
Hepatitis B virus (HBV) reactivation becomes a challenging issue with increasing use of immunosuppressive agents and cytotoxic chemotherapy for varied medical conditions, including cancer. The spectrum of HBV reactivation in the setting of immunosuppression may vary from asymptomatic reactivation to liver failure leading to death. HBV reactivation can hamper the course of planned therapies and diminish the effects of therapies; thus, it adversely affects the prognosis of the original disease and the survival of the patients. There is mounting evidence that HBV reactivation can be prevented and managed if patients are screened to determine their risk for HBV reactivation and are treated prophylactically before therapy with immunosuppressive agents or cytotoxic chemotherapy is initiated. In this article, we review the diagnostic criteria and clinical outcomes of HBV reactivation, discuss how immunosuppressive therapy may influence the risk of HBV reactivation, and outline strategies to prevent HBV reactivation.

Abstract
Hepatitis B virus (HBV) poses a significant challenge for both dialysis patients and kidney transplant recipients despite its decreasing rates, especially in developed countries. The best preventive method is vaccination. Patients with chronic renal disease should ideally be vaccinated prior to dialysis, otherwise, reinforced vaccination practices and close antibody titer monitoring should be applied while on dialysis. HBV infected dialysis patients who are renal transplant candidates must be thoroughly examined by HBV-DNA, and liver enzyme testing and by liver biopsy. When needed, one must consider treating patients with tenofovir or entecavir rather than lamivudine. Depending on the cirrhosis stage, dialysis patients are eligible transplant recipients for either a combined kidney-liver procedure in the case of decompensated cirrhosis or a lone kidney transplantation since even compensated cirrhosis after sustained viral responders is no longer considered an absolute contraindication. Nucleoside analogues have led to improved transplantation outcomes with both long-term patient and graft survival rates nearing those of HBsAg(-) recipients. Moreover, in the cases of immunized HBsAg(-) potential recipients with concurrent prophylaxis, we are enabled today to safely use renal grafts from both HBsAg(+) and HBsAg(-)/anti-HBc(+) donors. In so doing, we avoid unnecessary organ discarding. Universal prophylaxis with entecavir is recommended in HBV kidney recipients and should start perioperatively. One of the most important issues in HBV(+) kidney transplantation is the duration of antiviral prophylaxis. In the absence of robust data, it seems that prophylactic treatment may be discontinued in selected stable, low-risk recipients during maintenance immunosuppression and should be reintroduced when the immune status is altered. All immunosuppressive agents in kidney transplantation can be used in HBV(+) recipients. Immunosuppression is intimately associated with increased viral replication; thus it is important to minimize the total immunosuppression burden long term.

Abstract
The emergence of antiviral drug-resistant mutants is the most important issue in current antiviral therapy. As obligate parasites, viruses require host factors for efficient replication. An ideal therapeutic target to prevent drug-resistance development is represented by host factors that are crucial for the viral life cycle. Recent studies have indicated that heat shock protein 90 (HSP90) is a crucial host factor that is required by many viruses for multiple phases of their life cycle including viral entry, nuclear import, transcription, and replication. In this review, we summarize the most recent advances regarding HSP90 function, mechanisms of action, and molecular pathways that are associated with viral infection, and provide a comprehensive understanding of the role of HSP90 in the immune response and exosome-mediated viral transmission. In addition, several HSP90 inhibitors have entered clinical trials for specific cancers that are associated with viral infection, which further implies a crucial role for HSP90 in the malignant transformation of virus-infected cells; as such, HSP90 inhibitors exhibit excellent therapeutic potential. Finally, we describe the challenge of developing HSP90 inhibitors as anti-viral drugs.

Abstract
CONTEXT Due to the close relationship between the immune system and the hepatitis B virus (HBV) replication, it is essential to monitor patients with current or past HBV infection under any type of immunosuppression. Cancer chemotherapy, immunosuppressive therapies in autoimmune diseases, and immunosuppression in solid organ and stem cell transplant recipients are the major reasons for hepatitis B virus reactivation (HBVr). In this review, the challenges associated with HBVr are discussed according to the latest studies and guidelines. We also discuss the role of treatments with different risks, including anti-CD20 agents, tumor necrosis factor-alpha (TNF-α) inhibitors, and other common immunosuppressive agents in various conditions. EVIDENCE ACQUISITION Through an electronic search of the PubMed, Google Scholar, and Scopus databases, we selected the studies associated with HBVr in different conditions. The most recent recommendations were collected in order to reach a consensus on how to manage patients at risk of HBVr. RESULTS It was found that the positive hepatitis B surface antigen (HBsAg), the high baseline HBV DNA level, the positive hepatitis B virus e antigen (HBeAg), and an absent or low hepatitis B surface antibody (HBsAb) titer prior to starting treatment are the most important viral risk factors. Furthermore, rituximab, anthracycline, and different types of TNF-α inhibitors were identified as the high-risk therapies. By analyzing the efficiency of prophylaxis on the prevention of HBVr, it was concluded that those with a high risk of antiviral resistance should not be used in long-term immunosuppressants. Receiving HBV antiviral agents at the commencement of immunosuppressant therapy or chemotherapy was demonstrated to be effective in decreasing the risk of HBVr. Prophylaxis could also be initiated before the start of therapy. For most immune suppressive regimes, antiviral therapy should be kept up for at least 6 months after the cessation of immunosuppressive drugs. However, the optimal time of prophylaxis keeping should be increased in cases associated with rituximab or hematopoietic stem cell transplants. According to the latest studies and guidelines from different bodies, recommendations regarding screening, monitoring, and management of HBVr are outlined. CONCLUSIONS Identification of patients at the risk of HBVr before immunosuppressive therapy is an undeniable part of treatment. Starting the antiviral therapy, based on the type of immunosuppressive drugs and the underlying disease, could lead to better management of disease.

Abstract
Introduction The effect of chronic hepatitis B virus (HBV) infection on pregnancy is not clear. Hepatitis B virus infection of newborns in the case of natural delivery occurs in 70-90% of cases. Risk factors of infection are the presence of serum HBeAg and HBV DNA level above 107 IU/ml. Active and passive prevention protect more than 95% of neonates born to mothers infected with HBV. The aim of the study was to determine the course of pregnancy in HBV-infected women, the mode of delivery, efficacy of prophylaxis against HBV infection in newborns, and health condition of newborns within the first years of life. Material and methods The course of 104 pregnancies in 69 women infected with HBV was monitored. Hepatitis B virus viral load was determined by PCR using the AmpliPre/COBAS TaqMan HBV system. Neonatal HBV infection and the health condition at birth and during the first year of life were analyzed. Results All included pregnant women were HBeAg negative. No clinically significant disorders were observed during pregnancy. Viral load measured in the third trimester did not exceed 107 IU/ml in any pregnant woman. Only 5 (8%) of them demonstrated levels above 105 IU/ml. Two women (1.9%) experienced a miscarriage, which was considered as not associated with HBV infection. The majority (56%) of pregnancies ended with spontaneous labor. Complete prevention against HBV was applied in 79% of newborns. Hepatitis B virus infection was diagnosed in 3 children who received incomplete or no prophylaxis. Hepatitis B virus infection occurred in 3 (2.9%) children born naturally, who did not receive proper prevention after delivery. The Apgar score in children born to mothers infected with HBV did not differ significantly from that in neonates born to healthy women from the same population. Allergic disorders developed in 17 children who underwent HBV prophylaxis. Conclusions Low viral load in pregnant women infected with HBV and the absence of HBeAg reduce the probability of infection of newborns. Proper prevention carried out after delivery seems to be the most important method to prevent HBV infection in newborns.

Abstract
INTRODUCTION Management of patients with severe immune-mediated uveitis requires the use of immunosuppressive (IS) drugs in selected cases. This may be particularly challenging in certain patients with associated conditions, which may increase the risk of side effects or modify guidelines for the use of such drugs. Chronic viral and mycobacterial infections in the setting of non-infectious uveitis create a number of diagnostic but also therapeutic dilemmas to clinicians because they can be exacerbated by IS therapies with detrimental effects. AREAS COVERED In this review, we will focus on very specific chronic infections that can be affected by IS therapies: human immunodeficiency virus infection, chronic hepatitis virus infection and tuberculosis. The main aim of this review is to provide an updated and comprehensive practical guide for practitioners regarding the therapeutic decision-making and management of patients with non-infectious uveitis affected by the aforementioned infectious conditions. EXPERT OPINION Clinicians should be aware of the risk of viral and mycobacterial reactivation of an underlying infection during IS therapy. However, most of these conditions do not represent an absolute contraindication if one were able to apply an appropriate prior screening and close monitoring of such therapy.

Abstract
UNLABELLED Hepatitis B virus (HBV) reactivation during immunosuppression can lead to severe acute hepatitis, fulminant liver failure, and death. Here, we investigated hepatitis B surface antigen (HBsAg) genetic features underlying this phenomenon by analyzing 93 patients: 29 developing HBV reactivation and 64 consecutive patients with chronic HBV infection (as control). HBsAg genetic diversity was analyzed by population-based and ultradeep sequencing (UDS). Before HBV reactivation, 51.7% of patients were isolated hepatitis B core antibody (anti-HBc) positive, 31.0% inactive carriers, 6.9% anti-HBc/anti-HBs (hepatitis B surface antibody) positive, 6.9% isolated anti-HBs positive, and 3.4% had an overt HBV infection. Of HBV-reactivated patients, 51.7% were treated with rituximab, 34.5% with different chemotherapeutics, and 13.8% with corticosteroids only for inflammatory diseases. In total, 75.9% of HBV-reactivated patients (vs. 3.1% of control patients; P<0.001) carried HBsAg mutations localized in immune-active HBsAg regions. Of the 13 HBsAg mutations found in these patients, 8 of 13 (M103I-L109I-T118K-P120A-Y134H-S143L-D144E-S171F) reside in a major hydrophilic loop (target of neutralizing antibodies [Abs]); some of them are already known to hamper HBsAg recognition by humoral response. The remaining five (C48G-V96A-L175S-G185E-V190A) are localized in class I/II-restricted T-cell epitopes, suggesting a role in HBV escape from T-cell-mediated responses. By UDS, these mutations occurred in HBV-reactivated patients with a median intrapatient prevalence of 73.3% (range, 27.6%-100%) supporting their fixation in the viral population as a predominant species. In control patients carrying such mutations, their median intrapatient prevalence was 4.6% (range, 2.5%-11.3%; P<0.001). Finally, additional N-linked glycosylation (NLG) sites within the major hydrophilic loop were found in 24.1% of HBV-reactivated patients (vs. 0% of chronic patients; P<0.001); 5 of 7 patients carrying these sites remained HBsAg negative despite HBV reactivation. NLG can mask immunogenic epitopes, abrogating HBsAg recognition by Abs. CONCLUSION HBV reactivation occurs in a wide variety of clinical settings requiring immune-suppressive therapy, and correlates with HBsAg mutations endowed with enhanced capability to evade immune response. This highlights the need for careful patient monitoring in all immunosuppressive settings at reactivation risk and of establishing a prompt therapy to prevent HBV-related clinical complications.

Abstract
INTRODUCTION TNF-α is a pro-inflammatory cytokine known to a have a key role in the pathogenesis of chronic immune-mediated diseases. TNF-α inhibitors can be administered either as monotherapy or in combination with other anti-inflammatory or disease-modifying anti-rheumatic drugs (DMARDs) to treat chronic immune-mediated diseases. AREAS COVERED Patients receiving TNF-α inhibitors are at high risk of infections. Based on our experience, in this paper, we discuss the risk of infections associated with the administration of TNF-α inhibitors and the strategies for mitigating against the development of these serious adverse events. EXPERT OPINION Infliximab more so than etanercept appears to be responsible for the increased risk of infections. Re-activation of latent tuberculosis (LTB) infection and the overall risk of opportunistic infections should be considered before beginning TNF-α inhibitor therapy. A careful medical history, Mantoux test and chest-x-ray should always be performed before prescribing TNF-α inhibitors. Particular attention should be paid to risk factors for Pneumocystis jirovecii infection. Hepatitis B and C virological follow-up should be considered during TNF-α inhibitor treatment. Finally, patients who are at high risk of herpes zoster (HZ) reactivation would benefit from a second vaccination in adulthood when receiving TNF-α inhibitors.

Abstract
Glucocorticoid receptor (GR) function is essential for glucocorticoid action on various effector cells. The aim of the present study was to investigate the mRNA expression profiles of GRα and GRβ in peripheral blood mononuclear cells (PBMC) and examine the association between the expression levels of the GR isoforms and the serological and virological hepatitis B virus (HBV) status in patients with chronic hepatitis B (CHB). A total of 29 CHB patients were examined in the present study, which were divided into subgroups according to serological and virological markers. The levels of GRα and GRβ in PBMCs, HBV viral loads, HBV surface antigen (HBsAg), HBV e antigen (HBeAg) and pre‑S1Ag were measured. A total of 43 healthy individuals served as controls. GRα was present in the PBMCs of all CHB patients and healthy controls, whereas GRβ‑specific products were present in only 93.1% of the CHB patients and 86.0% of the healthy controls. The GRα levels were positively correlated with the expression of GRβ in the CHB patients (r=0.419; P<0.05) and were significantly lower compared with those observed in the healthy controls (60.51 ± 23.73, vs. 100.00 ± 40.75; P<0.001). Compared with the healthy controls, significant differences were observed in the mRNA expression of GRα in the CHB patients when stratified according to the HBeAg, pre‑S1Ag and HBV viral load status (P<0.05), but not in the pre‑S1Ag‑positive patients. These data demonstrated that the mRNA expression profile of GRα differed between the CHB patients and the healthy controls. In addition, the HBV serological and virological markers were not associated with the mRNA levels of the GR isoforms in the CHB patients.

Abstract
Mixed cryoglobulinemia is occasionally seen in patients with hepatitis B virus (HBV) infection. This report presents the case of a quiescent HBV carrier who had type II mixed cryoglobulinemia, protracted purpura, ulcerative skin lesions and advanced chronic kidney disease. The cutaneous manifestations of the patient improved along with a decrease in the serum cryoglobulin and HBV-deoxyribonucleic acid levels following the initiation of oral entecavir in combination with plasmapheresis. However, the patient ultimately required prednisolone due to the limited benefits of these treatments. We also discuss various concerns regarding steroid treatment in patients with mixed cryoglobulinemia complicated by HBV infection.

Abstract
Background: Hepatitis B virus (HBV) reactivation may occur with chemotherapy and has significant morbidity and mortality. The United States Centre for Disease Control and Prevention recommends pre-chemotherapy hepatitis B screening for all cancer patients, while the American Society of Clinical Oncology finds that there is insufficient evidence currently to support such a recommendation. Apart from anthracyclines, HBV reactivation rates from other commonly used chemotherapy regimens in solid tumours are not well described. Methods: We compared HBV reactivation risk in patients receiving several commonly used chemotherapy regimens for solid tumours associated with different immunosuppression risk at a tertiary cancer centre in an HBV endemic region. Results: A total of 1149 patients were identified, including 434, 196, 245 and 274, respectively, who received doxorubicin-based, oxaliplatin- or irinotecan-based, carboplatin/gemcitabine, and capecitabine chemotherapy. HBV screening rate was 39% overall. Thirty out of 448 (7%) screened patients were HBsAg positive and 28 out of 30 received prophylactic antiviral therapy with no reactivation. Three out of 1149 patients overall (0.3%) developed HBV reactivation, all from the unscreened doxorubicin group (3 out of 214, 1.4%). No unscreened patients (0 out of 487) in the other three treatment groups developed reactivation (P<0.001). Conclusion: Not all chemotherapy regimens result in HBV reactivation. Routine hepatitis B screening for low- or moderate-risk regimens may not be warranted.

Abstract
AIM The number of outpatients receiving systemic chemotherapy in Japan has recently increased. We retrospectively examined whether hepatitis B virus (HBV) carriers were safely treated and managed with systemic chemotherapy or biologic agents as outpatients at our oncology center. METHODS A total of 40 115 consecutive infusion chemotherapy or biologic therapies were administrated to 2754 outpatients in the Chemotherapy and Oncology Center at Osaka University Hospital from December 2003 to March 2011. We first studied the prevalence of outpatients with hepatitis B surface antigen (HBsAg), and then retrospectively evaluated a database to determine the frequencies of testing for other HBV-related markers and the incidence of developing hepatitis or HBV reactivation in patients positive for HBsAg. As a control for comparison, we also examined these same factors in patients with hepatitis C virus antibody (anti-HCV). RESULTS The majority of physicians at our hospital screened for HBsAg (95%) and anti-HCV (94%) prior to administrating chemotherapy. Of the 2754 outpatients, 46 (1.7%) were positive for HBsAg and 90 (3.3%) were positive for anti-HCV. Fifteen patients that were HBsAg positive were treated with lamivudine or entecavir prior to chemotherapy. None of the patients with HBsAg taking a prophylactic antiviral developed hepatitis, and only one breast cancer patient without prophylactic antiviral treatment (1/31 [3.2%]) developed hepatitis due to HBV reactivation. CONCLUSION HBV reactivation occurred in outpatients without prophylactic antiviral treatment, but the incidence was relatively low.

Abstract
Reactivation of hepatitis B virus (HBV) or hepatitis C virus (HCV) infection following anticancer chemotherapy and immunosuppressive therapy is a well-known complication. HBV reactivation has been reported to be associated with anti-CD20 monoclonal antibody rituximab-containing chemotherapy and tumor necrosis factor-α inhibitor-containing immunosuppressive therapy in HBV resolved patients (hepatitis B surface antigen negative and antibodies against hepatitis B core antigen positive and/or antibodies against surface antigen positive). On the other hand, HCV reactivation has been reported to be associated with liver damage or hepatic dysfunction, but fulminant hepatitis due to HCV reactivation is a rare complication. In this review, we describe the pathophysiology of the reactivation of HBV and HCV infection, as well as the clinical evidence and management of HCV reactivation.

Abstract
Patients with chronic hepatitis B virus (HBV) infection are at an increased risk for a severe and a potentially fatal viral reactivation following anti-cancer therapy. The molecular mechanism for this induction of HBV expression is still unclear. Here, we show that treating hepatoma cell line expressing HBV with various anti-cancer cytotoxic agents results in a significant up-regulation of HBV expression. This HBV induction is at the transcriptional level and is time dependent. Interestingly, treating hepatoma cells with anti-cancer cytotoxic agents results in a robust induction of peroxisome proliferator-activated receptor-gamma coactivator-1α (PGC-1α), a metabolic and energy regulator that is normally induced in the liver under starvation conditions and that has been previously shown to strongly coactivate HBV transcription. Most importantly, HBV up-regulation following anti-cancer therapy depends on PGC-1α induction, because PGC-1α knock-down abolishes HBV induction. Finally, pretreatment of HBV-expressing cells with the antioxidant agent N-acetylcysteine attenuates the induction of both PGC-1α and HBV in response to anti-cancer treatment, suggesting that chemotherapy-associated PGC-1α induction is mediated by cellular oxidative stress that ultimately leads to HBV up-regulation. We conclude that cytotoxic anti-cancer chemotherapy has a direct and an immune system-independent effect on HBV gene expression, which is mediated by PGC-1α. Our results attribute to this metabolic regulator an unexpected role in linking anti-cancer treatment to HBV reactivation and make PGC-1α a potential target for future anti-HBV therapy, especially under conditions in which it is robustly induced, such as following anti-cancer treatment.

Abstract
Hepatitis B virus (HBV) may be reactivated after chemotherapy or immunosuppressive therapy, and therefore administration of antiviral agents before such treatment is recommended. Most reported cases of reactivation are associated with high doses of immunosuppressive agents or combination therapy. We present a case of a previously inactive HBV carrier with an acute severe flare-up during a long-term, very-low-dose (2.5 mg/day) steroid treatment for rheumatoid arthritis. We suggest that even a minimal dose of single-regimen oral steroid can cause reactivation of indolent, inactive HBV.

Abstract
Immunosuppressive therapy can induce viral reactivation in patients with chronic hepatitis B virus (HBV) infection and, more rarely, in patients with resolved HBV infection. We report the case of a 57-year-old Japanese woman with rheumatoid arthritis (RA) who developed de-novo hepatitis B virus-related hepatitis after methotrexate (MTX) therapy. Entecavir and oral prednisolone following steroid pulse therapy were administered and her liver function recovered. MTX is widely used for RA for its efficiency and safety. But some cases of HBV reactivation caused by MTX, including de-novo hepatitis, have been reported. Considering these conditions, more attention should be paid when using MTX in patients with RA. And more studies are needed to determine who needs screening of HBV, monitoring of HBV-DNA, and prophylaxis with chemotherapy or immunosuppressive therapy.

Abstract
In ordinary settings, human immunodeficiency virus (HIV)-associated nephropathy should be considered when HIV infection is associated with heavy proteinuria. On the other hand, hepatitis B virus (HBV) may also play a role in the development of glomerular injury among patients with HIV infection, since HIV and HBV infections commonly occur together due to shared modes of transmission. We present here a case of nephrotic syndrome in an HIV-positive patient complicated with HBV infection. A renal biopsy revealed sparse granular deposits of immunoglobulin G in the subepithelial region, consistent with membranous nephropathy (MN) stage I. Moreover, immunostaining exhibited weak anti-hepatitis B core activity within glomeruli. These results led us to consider that HBV-associated MN might play a role in the development of nephrotic syndrome. Although anti-viral treatment for patients with HBV-associated MN has been suggested to be clinically effective, the use of two anti-HIV agents (tenofovir and emtricitabine), both of which have anti-HBV activities, was not effective for the patient's nephrotic syndrome, despite obtaining a decrease in the serum HBV-DNA levels. A lack of prospective data suggests that many decisions on the treatment of glomerulopathies with HIV infections are potentially empirical. Obviously, further studies and accumulated clinical experience are required to better determine the pathogenesis and management of HBV-associated MN among patients with HIV infections.

Abstract
BACKGROUND AND AIM A recent meta-analysis has demonstrated an association between hepatitis C virus and non-Hodgkin lymphoma (NHL). There is also evidence on the association between hepatitis B virus (HBV) and NHL. The aim of this study was to evaluate this evidence using a meta-analytic approach. METHODS We searched the MEDLINE database from 1962 to 2008 for case-control studies that have reported the association of HBV with NHL. We calculated the odds ratio (OR) and 95% confidence intervals (CI) to assess the prevalence of HBV infection and pooled the results using three different statistical models. RESULTS Our search yielded 12 studies with 11 studies (3262 NHL patients, 1,523,205 controls) evaluating HBV infection in NHL and one study (3888 HBV-infected individuals, 205,203 controls) that had investigated for NHL in HBV infection. The OR of detecting HBV infection in NHL when compared with the control population was 2.56 (95% CI, 2.24-2.92) by the fixed effects model; 2.61 (95% CI, 2.29-2.98) by the exact method and 2.67 (95% CI, 2.04-3.49) by the random effects model suggesting a high prevalence of HBV carrier state in lymphoma. There was evidence of statistical heterogeneity which disappeared after exclusion of retrospective studies on sensitivity analysis. CONCLUSIONS The results of this study suggest a possible causal relation between HBV infection and NHL which needs to be confirmed by experimental and epidemiological studies. In countries where prevalence of HBV infection is 1% or more, it may be prudent to screen patients with NHL for occult HBV infection.

Abstract
We present a case of reactivation of chronic hepatitis B virus (HBV) infection by a steroid-producing adrenal tumour. The tumour caused a reactivation and subsequent flare of the patients' HBV. The adrenal tumour was treated with an adrenalectomy and as a consequence the patients' transaminitis and viral load fell rapidly without the need for any additional hepatitis B treatment. The role of hepatitis B and steroid priming is discussed and the possible immunological mechanisms that underpin this phenomenon.

Abstract
Although the clinical benefits of antiviral treatment in the management of membranous nephropathy (MN) in patients with chronic hepatitis B virus (HBV) infection have been suggested, it should be evaluated more carefully. In this report, we present two cases with quiescent HBV who were administered lamivudine for either the initial treatment of MN or to control the reactivation of HBV during treatment with corticosteroids. No clinical benefit of lamivudine as an initial treatment was observed in one patient, which obliged us to commence administration of prednisolone (PSL). On the other hand, lamivudine seemed to play a pivotal role in the remission of an acute exacerbation of hepatitis B during treatment with PSL and mizoribine in the other patient. These two patients seemed to tolerate administration of PSL with or without an immunosuppressive agent well, since gradual and prompt improvements of nephrotic status were confirmed within a few months, thus suggesting the potential benefit of steroid treatment. There is little consensus regarding the optimal choice of steroids and immunosuppressants for the treatment of MN with chronic HBV infection, due to the potential for stimulation of viral replication and precipitation of hepatic flares. Our observations, however, suggest that treatment with PSL still should be reserved for quiescent HBV carriers with MN. Further studies will be required to determine the optimal timing and appropriate duration of antiviral treatment in such patients requiring long-term immunosuppression.

Abstract
BACKGROUND Hepatitis B virus (HBV) reactivation is a fatal complication in patients who receive chemotherapy or immunosuppressive therapy. We examined the effect of preventive entecavir (ETV), a new nucleoside analogue on HBV reactivation during chemotherapy or immunosuppressive therapy. METHODS Between February 2007 and September 2009, sixteen nucleoside analogue treatment-naive patients with chronic HBV infection (HB surface antigen [HBsAg] positive) who required chemotherapy or immunosuppressive therapy were enrolled. Referring to some guidelines, the patients received preventive ETV to reduce incidence of HBV reactivation, and were closely monitored for HBV markers. RESULTS HBV reactivation did not occur in any of the 16 patients and the indispensable treatments for their underlying diseases could be continued. However, HBV relapsed after preventive ETV was discontinued in 2 patients. CONCLUSIONS This study suggests that ETV is a useful option for preventing HBV reactivation in patients with chronic HBV infection.

Abstract
Of patients with severe exacerbation of chronic hepatitis B accompanied by jaundice and coagulopathy, 20%-30% have a fatal outcome. In this report, we describe 2 cases of severe exacerbation of chronic hepatitis B with jaundice and coagulopathy who were successfully treated with a combination of entecavir and corticosteroid. In both cases, rapid reductions in serum hepatitis B virus (HBV)-DNA levels were observed, and corticosteroid was stopped after serum HBV-DNA levels became undetectable. Entecavir treatment was continued. Generally, entecavir treatment reduced serum HBV-DNA levels rapidly, although the improvement in liver function was delayed by a few weeks. During this time lag, liver cell injury continued and the disease progressed. Corticosteroid suppressed the excessive host immune response and was useful for stopping progressive deterioration. A combination of entecavir and early-phase corticosteroid may be a useful treatment in severe exacerbation of chronic hepatitis B.

Abstract
Hepatitis B is endemic in many Asian countries and immunosuppression may precipitate hepatitic flare. There is little data on the treatment of hepatitis B in patients with systemic lupus erythematosus. We monitored serial transaminase and HBV DNA levels in our HBsAg-positive patients with a history of lupus nephritis and instituted anti-viral treatment in patients who showed virological reactivation. This retrospective pilot study reports the data with this pre-emptive management strategy. Amongst 228 patients with lupus nephritis, eight (3.51%) were HBsAg-positive and five had received Lamivudine treatment for hepatitis B. In two patients the virological flares were preceded by lupus flares that necessitated an increase in immunosuppressive treatment. Median HBV DNA level was 1.9 x 10(7) copies/mL (range 1.2 x 10(4)-1.0 x 10(9) copies/mL) at baseline, and it decreased by 2-5 logs after treatment. Four patients had abnormal transaminase levels at baseline, with mean alanine aminotransferase at 125.0 +/- 67.4 U/L, and all achieved normalisation after 3-24 months (median 13 months) of treatment. Discontinuation of Lamivudine treatment was attempted in three patients after 9-15 months. In one patient treatment was recommenced because of virological flare. For the remaining two patients in whom treatment was not interrupted, one showed sustained viral suppression and one developed drug resistance. All antiviral treatments were well-tolerated. These results indicate the importance of serial monitoring of HBV DNA and transaminase levels, and prompt anti-viral therapy, in the management of HBsAg-positive lupus patients. Also, it may be feasible to discontinue treatment in stable patients to avoid the selection of drug-resistant variants.

Abstract
PURPOSE Hepatitis B virus (HBV) and hepatitis C virus (HCV) are considered to be hepatotropic and are a major cause of hepatocellular carcinoma. However, little is known about the role of HBV and HCV infection in other malignancies. This study aimed to determine whether HBV and HCV infections increase the risk for pancreatic cancer development. PATIENTS AND METHODS At The University of Texas M. D. Anderson Cancer Center, Houston, TX, we recruited 476 patients with pathologically confirmed adenocarcinoma of the pancreas and 879 age-, sex-, and race-matched healthy controls. Blood samples were tested for the presence of HCV antibodies (anti-HCV), HBV surface antigen (HBsAg), antibodies against HBV core antigen (anti-HBc), and antibodies against HBsAg (anti-HBs). The positive samples were retested by two confirmatory tests. An unconditional multivariable logistic regression analysis was used to estimate adjusted odds ratios (AORs). RESULTS Anti-HCV was positive in seven cases (1.5%) and nine controls (1%). Anti-HBc was positive in 36 cases (7.6%) and 28 controls (3.2%). The estimated AORs and 95% CIs were as follows: anti-HCV-positive, 0.9 (95% CI, 0.3 to 2.8), anti-HBc-positive, 2.5 (95% CI, 1.5 to 4.2), anti-HBc-positive/anti-HBs-positive, 2.3 (95% CI, 1.2 to 4.2), and anti-HBc-positive/anti-HBs-negative, 4 (95% CI, 1.4 to 11.1). Risk modification by past exposure to HBV was observed among diabetics (AOR, 7.1; 95% CI, 1.7 to 28.7). CONCLUSION Past exposure to HBV may be associated with pancreatic cancer development. Should such findings be confirmed by other studies, it may offer important insights into the etiology of pancreatic cancer and may suggest the need to consider prevention of HBV reactivation among patients with HBV-related pancreatic cancer during chemotherapy.

Abstract
Although lamivudine (LAM) is a potent inhibitor of hepatitis B virus (HBV), prolonged therapy may induce the development of LAM-resistant strains, YMDD mutants. Although YMDD mutants have impaired replication that leads to a benign clinical course compared with wild-type virus, some immunosuppressive agents may enhance replication of YMDD mutants, causing a severe hepatitis flare. We retrospectively investigated the incidence and clinical outcomes of YMDD mutants in renal allograft recipients on immunosuppressive treatment. Clinical records of 25 renal allograft recipients, who underwent renal transplantation between December 1997 and February 2006 were hepatitis B surface antigen positive at the time of transplantation, were reviewed. All patients received LAM treatment after renal transplantation. Over 9 to 98 months of follow-up, 16 patients (64.0%) maintained undetectable HBV DNA levels; however, 9 patients (36.0%) showed persistent or increased levels of HBV DNA. Seven were identified as having developed YMDD mutants. Although genotypic analysis was not performed, YMDD mutants were strongly suspected in another two patients, who developed severe hepatic dysfunction combined with high levels of HBV viremia at close to 2 years of LAM therapy. One patient recovered after hepatic transplantation and another patient died of hepatic failure. In conclusion, the incidence of YMDD mutants was similar to that of nonimmunosuppressed individuals; however, the presence of these mutants made it more likely for severe liver disease to develop in renal transplant recipients. Therefore, close monitoring for the development of YMDD mutants should be performed during LAM treatment, especially in this group of patients.

Abstract
Introduction: The aim of this study was to ascertain the outcomes of chronic hepatitis B (CHB) infection following immunosuppressive therapy in 38 consecutive oriental patients with systemic rheumatic diseases.
Materials and Methods: This is a retrospective consecutive, non-comparative study.
Results: The majority of patients were female (26, 68.4%), predominantly Chinese (92.1%), with a mean age 54 ± 14 years (range, 16 to 87). The mean duration of rheumatic disease was 9 ± 11 years (range, 0.1 to 48), with rheumatoid arthritis (52.6%) and systemic lupus erythematosus (23.7%) being the most common. The mean duration of CHB infection was 6 ± 5 years (range, 0.1 to 17), with the majority diagnosed during pre-methotrexate screening (50.0%) and asymptomatic transaminitis following initiation of immunosuppressive therapy (23.7%). Upon diagnosis of rheumatic disease, all patients had normal alanine aminotransferase (ALT). Of these, 18.2% were positive for hepatitis B e antigen (HBeAg) and 78.1% were positive for anti-HBe antibody. Twenty (52.6%) developed ALT elevation, which was more than twice the upper limit of normal in 12 patients. ALT normalised spontaneously in 12 patients without hepatic decompensation or change in therapy. Seven (18.4%) patients received lamivudine for 18 ± 22 months (range, 2 to 61). Two patients developed YMDD mutation subsequently treated with adefovir (1) and adefovir/lamivudine (1). There were 3 (7.9%) hepatitis B virus (HBV)-unrelated deaths [infection (2), genitourinary malignancy (1)], and 1 from HBV-reactivation complicated by septicaemia. None have developed hepatocellular carcinoma.
Conclusion: Elevated ALT occurred in 52.6% of patients, with only 18.4% requiring anti-viral therapy for HBV reactivation. HBV-related mortality was low. With the appropriate precautionary measures, prednisolone and immunosuppressants (except methotrexate and leflunomide) may be used safely in patients where clinically indicated.

Abstract
INTRODUCTION Despite the development of potent, new antiviral drugs, the percentage of HBeAg seroconversion is approximately 35%. Immunosuppression before antiviral administration has recently been investigated with contradictory results. We evaluated the safety and efficacy of lamivudine and interferon alfa-2b with prior immunosuppression with prednisone in patients with HBeAg-positive chronic hepatitis B (CHB). METHODS A randomized controlled study was conducted in a sample of 44 patients with HBeAg-positive CHB and persistently elevated alanine transferase (ALT) levels. The patients were distributed into two groups: 22 patients received prednisone 40 mg daily for 4 weeks, followed by 2 weeks without treatment, and lamivudine 150 mg daily for 4 weeks; lamivudine plus interferon alfa 2b (10 MIU every other day) was then administered for 24 weeks followed by continuous lamivudine 150 mg daily to complete 58 weeks. A further 22 patients received the same treatment regimen and duration, but without prednisone. RESULTS Virologic response defined as HBeAg seroconversion plus a decrease of serum HBV DNA < 105 copies/ml 24 weeks after concluding the treatment was observed in 68% of the patients receiving previous immunosuppression compared with 54% of the control group (p = 0.26). Forty-five percent of patients with prednisone priming showed histologic improvement compared with 23% of the control group (p = 0.10). A significant proportion of patient with previous immunosuppression showed improvement in necroinflammatory activity (45% vs 23%) and fibrosis (50 vs 23%) compared with the control group. CONCLUSIONS Virologic response was clinically, but not statistically, superior in the group with prednisone priming. Histologic improvement was notable in the group with previous immunosuppression.

Abstract
BACKGROUND & AIMS De novo hepatitis B virus (HBV)-related hepatitis after chemotherapy results in high morbidity and mortality. We evaluate the clinical course of de novo HBV-related hepatitis after chemotherapy. METHODS Two hundred forty-four consecutive hepatitis B surface antigen (HBsAg)-negative lymphoma patients treated with chemotherapy were followed up for a median of 12.4 (range, 0.1-65.0) months. Serially collected serum samples were analyzed for hepatitis, serum HBV DNA, and HBsAg seroreversion. RESULTS Eight of the 244 patients (3.3%) developed de novo HBV-related hepatitis. A 100-fold increase in serum HBV DNA preceded de novo HBV-related hepatitis by a median of 18.5 (range, 12-28) weeks. All 8 patients had normal serum alanine aminotransaminase level when the 100-fold increase in serum HBV DNA occurred. Patients with de novo HBV-related hepatitis were more likely to have occult HBV infection before chemotherapy. Direct sequencing results showed that these 8 patients had de novo HBV-related hepatitis from reactivation of occult HBV infection. Three of the 8 patients with de novo HBV-related hepatitis compared with 6 of the 236 patients without de novo HBV-related hepatitis developed fulminant hepatic failure (37.5% vs 2.5%, respectively, P < .001). On multivariate Cox analysis, de novo HBV-related hepatitis was independently associated with a higher risk of fulminant hepatic failure (relative risk, 29.854; 95% confidence interval: 4.844-183.980; P < .001). CONCLUSIONS Close surveillance for a 100-fold increase in HBV DNA is recommended for HBsAg-negative patients treated with chemotherapy so that early commencement of antiviral therapy can be initiated before the occurrence of de novo HBV-related hepatitis.
