Chen D, Yu R, Yin S, Qiu W, Fang J, Peng XE. Hepatitis B virus infection as a risk factor for chronic kidney disease: a systematic review and meta-analysis. BMC Infect Dis 2024; 24:620. [PMID: 38909191 PMCID: PMC11193185 DOI: 10.1186/s12879-024-09546-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Accepted: 06/20/2024] [Indexed: 06/24/2024] Open
Abstract
BACKGROUND Currently, several studies have observed that chronic hepatitis B virus infection is associated with the pathogenesis of kidney disease. However, the extent of the correlation between hepatitis B virus infection and the chronic kidney disease risk remains controversial. METHODS In the present study, we searched all eligible literature in seven databases in English and Chinese. The random effects model was used to conduct a meta-analysis. Quality of included studies was assessed using the Newcastle-Ottawa Quality Scale. RESULTS In this analysis, a total of 31 studies reporting the association between hepatitis B virus infection and chronic kidney disease risk were included. The results showed a significant positive association between hepatitis B virus infection and the risk of chronic kidney disease (pooled OR, 1.20; 95% CI, 1.12-1.29), which means that hepatitis B virus increases the risk of developing chronic kidney disease. CONCLUSION This study found that hepatitis B virus infection was associated with a significantly increased risk of chronic kidney disease. However, the current study still cannot directly determine this causal relationship. Thus, more comprehensive prospective longitudinal studies are needed in the future to provide further exploration and explanation of the association between hepatitis B virus and the risk of developing chronic kidney disease.

[PMID: 38675959 PMCID: PMC11055091 DOI: 10.3390/v16040618] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2024] [Revised: 04/11/2024] [Accepted: 04/13/2024] [Indexed: 04/28/2024] Open
Abstract
Hepatitis B virus (HBV) infections affect approximately 296 million people around the world, and the prevalence of any past or present HBV infection during the years 2015-2018 was as high as 4.3%. Acute HBV infection often presents with nonspecific symptoms and is usually self-limited, but 5% of patients can have persistent infections leading to chronic HBV infection and the risk of turning into chronic HBV infection is significantly higher in babies with vertical transmission (95%). Patients with chronic HBV infection are usually asymptomatic, but 15 to 40% of chronic HBV carriers develop cirrhosis and/or hepatocellular carcinoma. In addition to liver-related disorders, HBV is also associated with several extrahepatic complications, including glomerulonephritis, cryoglobulinemia, neurologic disorders, psychological manifestations, polyarthritis, and dermatologic disorders. Making the diagnosis of HBV can be challenging since patients with chronic infections can remain symptom-free for decades before developing cirrhosis or hepatocellular carcinoma, and patients with acute HBV infection may have only mild, nonspecific symptoms. Therefore, understanding how this virus causes extrahepatic complications can help clinicians consider this possibility in patients with diverse symptom presentations. The pathophysiology of these extrahepatic disorders likely involves immune-related tissue injury following immune complex formation and inflammatory cascades. In some cases, direct viral infection of extrahepatic tissue may cause a clinical syndrome. Currently, the American Association for the Study of Liver Diseases recommends treatment of chronic HBV infections with interferon therapy and/or nucleos(t)ide analogs, and this treatment has been reported to improve some extrahepatic disorders in some patients with chronic HBV infection. These extrahepatic complications have a significant role in disease outcomes and increase medical costs, morbidity, and mortality. Therefore, understanding the frequency and pathogenesis of these extrahepatic complications provides important information for both specialists and nonspecialists and may help clinicians identify patients at an earlier stage of their infection.

Abstract
Hepatitis B virus (HBV) and hepatitis C virus (HCV) infect a significant number of individuals globally and their extra-hepatic manifestations, including glomerular disease, are well established. Additionally, liver disease-associated IgA nephropathy is the leading cause of secondary IgA nephropathy with disease course varying from asymptomatic urinary abnormalities to progressive kidney injury. Herein we provide an updated review on the epidemiology, pathogenesis, clinical manifestations, and treatment of HBV- and HCV-related glomerulonephritis as well as IgA nephropathy in patients with liver disease. The most common HBV-related glomerulonephritis is membranous nephropathy, although membranoproliferative glomerulonephritis and podocytopathies have been described. The best described HCV-related glomerulonephritis is cryoglobulinemic glomerulonephritis occurring in about 30% of patients with mixed cryoglobulinemic vasculitis. The mainstay of treatment for HBV-GN and HCV-GN is antiviral therapy, with significant improvement in outcomes since the emergence of the direct-acting antivirals. However, cases with severe pathology and/or a more aggressive disease trajectory can be offered a course of immunosuppression, commonly anti-CD20 therapy, particularly in the case of cryoglobulinemic glomerulonephritis.

Abstract
Acute kidney injury (AKI) is a common complication of cirrhosis, burdened by high morbidity and mortality rates and progression to chronic kidney disease. Hepatorenal syndrome (HRS) is a peculiar type of functional AKI observed in cirrhotic patients with ascites. HRS diagnosis is still clinical, once pre-renal azotemia and intrinsic kidney damage have been excluded by applying well-established and internationally adopted criteria. HRS is considered reversible because of the absence of intrinsic renal damage. However, HRS reversibility has been questioned, due to the lack of response to treatment with vasoconstrictors plus albumin in a relevant percentage of patients and to the persistence of renal dysfunction in HRS patients who underwent liver transplantation (LT). Indeed, LT is the only ultimate treatment, as it solves both liver failure and portal hypertension. Thus, the presence of renal damage in HRS can be hypothesized. In this scenario, neutrophil gelatinase-associated lipocalin (NGAL), one of the most promising biomarkers, may help in characterizing the type of renal injury, distinguishing between HRS and acute tubular necrosis. This review gathers the available evidence in favor and against the presence of structural lesions in HRS in terms of either renal histology and urinary biomarkers with a particular focus on NGAL. The ability to properly characterize which component of renal dysfunction prevails - functional rather than structural - entails a relevant clinical impact for the treatment of these patients, both in terms of medical therapy and liver vs. combined liver-kidney transplantation.

Abstract
Glomerular diseases are an important cause of kidney disease in patients with liver disease. Although kidney involvement due to tubular or vascular disease is more common, glomerular diseases became more prevalent as hepatitis infections increased and then subsequently decreased with the widespread availability of hepatitis A and B vaccines and the development of effective antiviral treatments for hepatitis B and C. In this review, we discuss the common glomerular pathologies that are seen in patients with liver disease and the current treatment options available to them.

Abstract
Kidney involvement with hepatitis B virus is varied and mostly limited to nephrotic syndrome with membranous nephropathy and nephritic syndrome with membranous proliferative glomerulonephritis. Lupus nephritis is associated with nephritic or nephrotic range proteinuria with most common finding of sub-endothelial electron-dense deposits and immunological stain demonstrating full-house picture with all immunological marker staining. Our case discusses a young male patient presenting with rapidly worsening renal function along with proteinuria, found to be positive for both hepatitis B core antibody along with hepatitis B surface antibody plus positive anti-neutrophilic antibody but negative anti-double-stranded DNA. Kidney biopsy demonstrated hepatitis B–associated lupus-like glomerulonephritis. He responded successfully with antiretroviral therapy and high-dose prednisone. Patient did not need lupus-specific treatment and recovered with antiretroviral therapy only. Hepatitis B–associated lupus-like glomerulonephritis has rarely been reported and possess a diagnostic and therapeutic challenge to all nephrologists.

Abstract
BACKGROUND AND AIMS Chronic kidney disease (CKD) usually occurs during the chronic infection of hepatitis B virus (HBV). However, the risk factors of CKD in an HBV population have not been completely demonstrated. Our present study aimed to investigate the risk factors of CKD in chronic HBV infection using a hospital based cross-sectional study in the northern area of China. METHODS During January 2013 to December 2017, a total of 94 patients with CKD complicated by chronic HBV infection were consecutively enrolled in the study, as well as 548 age- and sex-matched hepatitis B patients without CKD who were enrolled as controls. Univariate and multivariate regression analyses were used to determine the effects of each variable after adjusting for cofounding factors. RESULTS Multivariate analysis showed that HBeAg-positive status (odds ratio [OR]=2.099, 95% CI 1.128-3.907), dyslipidemia (OR: 3.025, 95% CI 1.747-5.239), and hypertension (OR: 12.523, 95% CI 6.283-24.958) were independently associated with the incidence of CKD, while duration of HBV infection (≥240 months) (OR: 0.401, 95% CI 0.179-0.894), Log10 HBsAg (OR: 0.514, 95% CI 0.336-0.786), and coronary heart disease (OR: 0.078, 95% CI 0.008-0.768) were protective factors for the incidence of CKD. Duration of HBV infection, Log10 HBsAg, HBeAg-positive status and dyslipidemia remained the risk factors for CKD after adjusting for diabetes mellitus, hypertension, and coronary heart disease. CONCLUSIONS Duration of HBV infection, Log10 HBsAg, HBeAg-positive status and dyslipidemia contributed to the incidence of CKD during chronic HBV infection in a Chinese population.

Abstract
Antibody detection by serological methods gained a lot of interest in recent years and has become the backbone of virological diagnosis. Despite the detection of all five classes of immunoglobulins in urine, not much attention has been paid to the use of urine as a diagnostic sample to detect viral antibodies. Unlike venipuncture, this non-invasive mode of sample collection can help cover all age groups, especially paediatric and old age patients, where blood collection is difficult. Using urine as a sample is also economical and involves lesser risk in sample collection. The antibodies are found to be stable in urine at room temperature for a prolonged period, which makes the sample transport management easier as well. A few recent studies, have also shown that the detection limit of antibodies in urine is at par with serum or other clinical material. So, the ease in sample collection, availability of samples in large quantity and stability of immunoglobulins in urine for prolonged periods can make urine an ideal sample for viral diagnosis.

Abstract
BACKGROUND This study investigated the association between the fibrinogen level and the risk of acute kidney injury (AKI) in patients who have undergone living donor liver transplantation (LDLT). PATIENTS AND METHODS A total of 676 patients who underwent LDLT were analyzed retrospectively. Exclusion criteria included a history of severe kidney dysfunction, emergency operation, deceased donor, ABO-incompatible transplantation, and missing data. The study population was divided into low and normal fibrinogen groups. A 1:1 propensity score (PS) matching analysis was used to evaluate the association between a low fibrinogen level (< 160 mg/dL) and postoperative development of AKI. RESULTS In total, 142 patients (23.1%) developed AKI after LDLT. The PS matching analysis showed that the probability of AKI was two-fold higher in the low fibrinogen group than in the normal fibrinogen group. In addition, patients with AKI had poorer postoperative outcomes such as longer hospitalization, longer ICU stay, and higher mortality than patients without AKI. CONCLUSIONS The preoperative fibrinogen level may be useful for risk stratification of patients undergoing LDLT in terms postoperative development of AKI.

Abstract
Viral infections in the immunocompetent host can cause both acute and chronic kidney disease either as a direct damage to the infected kidney cells or as a consequence of systemic immune responses that impact kidney function. Since identifying these entities in the 1970s and 80s, major breakthroughs in the understanding of the viral mechanisms have occurred. Viruses have evolved mechanisms to hijack signaling pathways of infected cells to evade antiviral immune responses by the host. Over time, the clinical presentations and management of these diseases have evolved along with our in-depth understanding of the various pathophysiological mechanisms causing these conditions. Similarly, both at the cellular and systemic levels, the host has evolved mechanisms to counter viral subversion strategies for mutual survival. Since the start of the current COVID-19 pandemic, numerous cases of acute kidney injury have been reported in the literature with various possible pathophysiological mechanisms. In this review, we summarize lessons learned from prior viral pandemics related to viral mechanisms utilized in the pathogenesis of numerous renal manifestations to attempt to utilize this knowledge in predicting post-COVID-19 kidney disease.

Abstract
Liver and kidney are strictly connected in a reciprocal manner, in both the physiological and pathological condition. The Italian Association for the Study of Liver, in collaboration with the Italian Society of Nephrology, with this position paper aims to provide an up-to-date overview on the principal relationships between these two important organs. A panel of well-recognized international expert hepatologists and nephrologists identified five relevant topics: 1) The diagnosis of kidney damage in patients with chronic liver disease; 2) Acute kidney injury in liver cirrhosis; 3) Association between chronic liver disease and chronic kidney disease; 4) Kidney damage according to different etiology of liver disease; 5) Polycystic kidney and liver disease. The discussion process started with a review of the literature relating to each of the five major topics and clinical questions and related statements were subsequently formulated. The quality of evidence and strength of recommendations were graded according to the GRADE system. The statements presented here highlight the importance of strong collaboration between hepatologists and nephrologists for the management of critically ill patients, such as those with combined liver and kidney impairment.

Abstract
Background: The immunogenicity against hepatitis B vaccine is unsatisfactory in the chronic kidney disease (CKD) patients, and studies evaluating augmented vaccine regimens to enhance immunogenicity have been inconclusive.Objectives: To evaluate the immunogenicity and safety of four-standard-dose and four-triple-dose regimens hepatitis B vaccine among CKD patients in China.Research design and methods: We conducted a multicenter, randomized, parallel-controlled trial including 273 patients with CKD who were randomly allocated to receive 3 or 4 doses of 20 or 60 µg of recombinant hepatitis B vaccine.Main outcome measures: Seroconversion rates, high-level response rates, and geometric mean concentrations (GMCs) of anti-HBs at months 3 and 7.Results: The seroconversion rates and high-level responses in the IM20 × 4 group and the IM60 × 4 group were higher than those in the IM20 × 3 group at months 3 and 7 (P < 0.05). The IM60 × 4 group had better immune responses than the IM20 × 4 group at month 3 (P < 0.05); however, no significant difference was noted at month 7 (P > 0.05).Conclusions: Both the four-standard-dose and four-triple-dose regimens improved immune response compared to the three-standard-dose regimen of hepatitis B vaccination in CKD patients, and the additional effect of higher dose was minimal.Trial registration: The trial is registered at ClinicalTrials.gov (CT.gov identifier: NCT03962881).

Abstract
While virus-specific antibodies are broadly recognized as correlates of protection, virus-specific T cells are important for direct clearance of infected cells. Failure to generate hepatitis B virus (HBV)-specific antibodies is well-known in patients with end-stage renal disease. However, whether and to what extent HBV-specific cellular immunity is altered in this population and how it influences humoral immunity is not clear. To address it, we analyzed HBV-reactive T cells and antibodies in hemodialysis patients post vaccination. 29 hemodialysis patients and 10 healthy controls were enrolled in a cross-sectional study. Using multiparameter flow cytometry, HBV-reactive T cells were analyzed and functionally dissected based on granzyme B, interferon-γ (IFN-γ), tumor necrosis factor alpha (TNF-α), interleukin-2 (IL-2), and IL-4 expression. Importantly, HBV-reactive CD4+ T cells were detected not only in all patients with sufficient titers but also in 70% of non-responders. Furthermore, a correlation between the magnitude of HBV-reactive CD4+ T cells and post-vaccination titers was observed. In summary, our data showed that HBV-reactive polyfunctional T cells were present in the majority of hemodialysis patients even if humoral immunity failed. Further studies are required to confirm their in vivo antiviral capacity. The ability to induce vaccine-reactive T cells paves new ways for improved vaccination and therapy protocols.

Abstract
Hepatitis B virus (HBV), influenza, pneumococcus and herpes zoster are important infections which could result in significant morbidity and mortality in patients with chronic kidney disease (CKD). While seroconversion rates after vaccination are often lower in CKD patients compared with healthy adults due to impaired innate and adaptive immunity, vaccinations for HBV, influenza, pneumococcus and herpes zoster are generally effective in reducing the transmission and/or severity of these infections. Practical issues that have an impact on the efficacy of vaccination in the CKD population include the timing, dose, schedule of vaccination, the route of administration, and adjuncts applied at time of vaccination. This review discusses the vaccination regimens and the efficacy of HBV, influenza, pneumococcus and zoster vaccines in CKD patients, and highlights recent advances in enhancing vaccine seroconversion rates.

Abstract
A 32-year-old man was referred to our clinic for evaluation of abnormal liver function tests and concurrent proteinuria. Physical examination revealed a maculopapular rash, involving the trunk and palms, and multiple 'moth-eaten' patches of alopecia. After a prolonged diagnostic work-up a hepatitis with concomitant nephrotic syndrome due to secondary syphilis was diagnosed. Treatment with benzylpenicillin led to complete clinical recovery. Syphilis is a re-emerging infectious disease with heterogeneous clinical presentation that should be considered in the differential diagnosis of inexplicable simultaneous liver and kidney dysfunction in patients with high-risk sexual behaviour.Syphilis is a re-emerging infectious disease with heterogeneous clinical presentation that should be considered in the differential diagnosis of inexplicable simultaneous liver and kidney dysfunction in patients with high-risk sexual behaviour.

Abstract
Introduction: Multiple studies have revealed a strong relationship between the development of nephropathy and hepatitis B virus (HBV) infection. The underlying pathogenesis of hepatitis B-related glomerulonephritis (HBV-GN) involves immune complexes, which can be isolated from kidney tissues. Clearance of HBV antigenemia improves renal impairment and proteinuria in HBV-GN patients.Areas covered: In this review, we present our current understanding of the epidemiology, pathogenesis, pathology, diagnosis, and treatment of HBV-GN. We discuss the advantages and disadvantages of oral nucleoside/nucleotide analogs (NAs), and the main pharmaceutical treatment for hepatis B.Expert opinion: Currently, antiviral agents are the main HBV-GN therapeutic agents. Although no randomized controlled clinical trials have compared the efficacy of interferon (IFN) and NA, we suggest IFN treatment for pediatric patients (IFN-α in patients ≥1 year; pegIFN-α in patients ≥3 years) considering treatment duration and absence of resistance. Novel NAs have brought about promising treatment options involving high efficacy viral suppression and low resistance rates. NAs with a high barrier to resistance (e.g. entecavir) are recommended as first-line therapy of HBV-GN. Immunosuppression monotherapy, such as corticosteroids, is of little benefit and potentially harmful to HBV-GN patients due to the possibility of viral reactivation.

Abstract
Introduction: Renal dysfunction commonly occurs in patients with cirrhosis and is typically associated with poor prognosis. Several pathophysiologic mechanisms are responsible for renal disease in these patients, prompt identification permits individualized management.Areas covered: Pathophysiology, evaluation and differential diagnosis, management and prognosis of renal disease in patients with cirrhosis. Special focus on management of hepatorenal syndrome and indications for simultaneous liver-kidney transplantation.Literature search methodology: a detailed literature search was performed using PubMed without date restrictions. Published guidelines and position papers were also used and cross-referenced to identify additional studies.Expert opinion: The prognostic significance of renal dysfunction in patients with cirrhosis is highlighted by the inclusion of serum creatinine in the model for end-stage liver disease (MELD). Both acute and chronic renal dysfunction result in increased mortality in patients with cirrhosis, although there are marked differences related to the etiology of renal disease. Early recognition and prompt intervention determined by the most likely etiology are key in the management of these patients. Simultaneous liver-kidney transplantation improves patient survival compared to isolated liver transplantation in patients with cirrhosis and persistent renal impairment; however, selection of candidates must be judicious and individualized due to the ongoing shortage of donor kidneys.

Abstract
AIM Renal toxicity of adefovir disoproxil (ADV) and tenofovir disoproxil fumarate (TDF) is a significant concern in chronic hepatitis B (CHB) patients. Early observational clinical data suggested that telbivudine (LdT) might have renoprotective effects. METHODS In this prospective study, consecutive CHB patients on combined lamivudine (LAM) + ADV/TDF were switched to LdT + ADV/TDF at recruitment and were followed up for 24 months. Estimated glomerular filtration rate (eGFR) was calculated with the modification of diet in renal disease equation. The effects of LdT on cell viability and expression of kidney injury or apoptotic biomarkers were investigated in cultured renal tubular epithelial cell line HK-2. RESULTS Thirty-one patients (median age 55 years, 90.3% male) were recruited (54.8% TDF: 45.2% ADV). Serum HBV DNA was undetectable at all time points. Median eGFR was 70.2 (IQR 62.6-77.9) and 81.5 (IQR 63.6-99.1) mL/min/1.73 m2 at baseline and 24 months, respectively (p < 0.001). Downstaging of chronic kidney disease was observed in eight (25.8%) patients and was more common in ADV-treated compared to TDF-treated patients (7/8 vs. 1/17, p = 0.011; OR 16, 95% CI 1.643-155.766, p = 0.017). In vitro data showed that adding LdT to ADV or TDF was associated with improved cell viability and lower expression of injury and apoptotic biomarkers compared with ADV or TDF alone. Treatment was prematurely discontinued in four(12.9%) patients due to myalgia. CONCLUSIONS Clinical and in vitro data suggest that LdT has renoprotective effects in patients on long-term ADV/TDF treatment. LdT may be considered as an adjuvant therapy in this special group of patients with renal impairment (NCT03778567).

Abstract
Autoimmune kidney diseases triggered by viruses are an important cause of kidney disease in patients affected by chronic viral infection. Hepatitis B virus (HBV) infection is associated with membranous nephropathy and polyarteritis nodosa. Hepatitis C virus (HCV) infection is a major cause of cryoglobulinemic glomerulonephritis. Patients with human immunodeficiency virus (HIV) may develop HIV-associated nephropathy, a form of collapsing focal segmental glomerulosclerosis, or various forms of immune-complex-mediated kidney diseases. This article summarizes what is known about the pathogenesis, diagnosis, and management of immune-mediated kidney diseases in adults with chronic HBV, HCV, and HIV infections.

Abstract
The liver plays a key role in the metabolism of proteins. Liver dysfunction affects many organs because it communicates with the spleen and all digestive organs through the portal vein. Additionally, the kidney is an organ that is closely related to the liver and is involved in liver diseases. Glomerulonephritis is an important extrahepatic manifestation of chronic hepatitis B virus (HBV) infection. Nucleos(t)ide analog (NA) therapy effectively suppresses HBV replication by inhibiting HBV polymerase, thus decreasing the levels of serum HBV-DNA and delaying the progression of cirrhosis. Although NA therapy is recommended for all patients with chronic HBV infection, regardless of the level of renal dysfunction, there is limited information on NA use in patients with chronic kidney disease. In addition, in patients with end-stage liver cirrhosis, hepatorenal syndrome can be fatal. Hence, we should take into account the stage of impaired renal function in patients with cirrhosis. The aims of this article are to review the epidemiology, clinical presentation, treatment, and prevention of HBV-associated nephropathy.

Chen YC, Li CY, Tsai SJ, Chen YC. Nationwide cohort study suggests that nucleos(t)ide analogue therapy decreases dialysis risk in Taiwanese chronic kidney disease patients acquiring hepatitis B virus infection. World J Gastroenterol 2018; 24:917-928. [PMID: 29491685 PMCID: PMC5829155 DOI: 10.3748/wjg.v24.i8.917] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2017] [Revised: 12/10/2017] [Accepted: 12/20/2017] [Indexed: 02/06/2023] Open
Abstract
AIM To investigate the risk of end-stage renal disease (ESRD) in hepatitis B virus (HBV)-infected patients with chronic kidney disease (CKD) with and without nucleos(t)ide analogue (NA) therapy.
METHODS This nationwide cohort study included 103444 Taiwanese CKD adults without hepatitis C virus infection from the Taiwan Longitudinal Health Insurance Database 2005 between 1997 and 2012. We identified 2916 CKD patients who acquired HBV infection and did not receive NAs (untreated cohort), and they were propensity-matched 1:4 with 11664 uninfected counterparts. We also identified 442 CKD patients who acquired HBV infection and received NAs (treated cohort), and they were propensity-matched 1:3 with 1326 untreated counterparts. The association between HBV infection, NA use, and ESRD was analyzed using competing risk analysis.
RESULTS Multivariable Cox regression analysis showed a 1.67-fold higher risk (P < 0.0001) of ESRD in the untreated cohort (16-year cumulative incidence, 10.1%) than in the matched uninfected cohort (16-year cumulative incidence, 6.6%), which was independent of cirrhosis or diabetes. The treated cohort (16-year cumulative incidence, 2.2%) had an 87% lower ESRD risk (P < 0.0001) compared with the matched untreated cohort (16-year cumulative incidence, 11.9%). The number needed to treat for one fewer ESRD after NA use at 12 years was 12. Multivariable stratified analyses verified these associations in all subgroups.
CONCLUSION This study suggests that untreated HBV infection and NA therapy are associated with increased and decreased risk of ESRD, respectively, in CKD patients. Identification of HBV status and targeted monitoring for ESRD development are important in CKD patients living in HBV-endemic areas.

Abstract
Renal involvement in hepatitis B occurs in various spectrums and its knowledge is important for clinicians in management of patients. The renal diseases most commonly associated with hepatitis B virus (HBV) infection include membranous nephropathy, membranoproliferative glomerulonephritis and Polyarteritis nodosa. The widespread use of hepatitis B vaccination has decreased the incidence of HBV-related renal diseases. The incidence of HBV infection in dialysis patients has significantly decreased over the past few decades because of screening of blood products for hepatitis B surface antigen (HBsAg) and hepatitis B core antibody, implementation of infection control measures and hepatitis B vaccination. The definition of acute kidney injury has been recently modified in cirrhotic population, helping in prognosis and prediction of mortality. The most common etiologies of acute kidney injury in this cirrhotic population, which account for 80% to 90% of all cases, include volume depletion, acute tubular necrosis and hepatorenal syndrome. Treatment with oral nucleoside/tide analogues (NA) brought a new paradigm in the management of HBsAg positive glomerulonephritis, kidney transplant recipients and dialysis patients, resulting in effective viral suppression, reduced hepatic complications and improved patient survival, without compromising renal allograft outcome. NAs are cleared by the kidneys and therefore their dosage has to be adjusted in all patients with impaired renal function. This article reviews the recent knowledge of the pathogenesis and treatment of HBV-related glomerulonephritis and discusses the management of hepatitis B in patients on dialysis, kidney transplant recipients and cirrhotics, which is continuously evolving.

Abstract
BACKGROUND Nucleos(t)ide analogs (NUCs) are the standard of care for chronic hepatitis B (CHB). The present analysis aimed to determine the cost effectiveness of NUCs in Chinese healthcare settings. METHODS A Markov model was used to simulate two therapeutic strategies for a hypothetical patient cohort diagnosed with hepatitis B e antigen-positive CHB, unwilling or unable to receive interferon therapy, and about to start treatment with any NUC. The first strategy included NUC monotherapy without sequencing (telbivudine [LDT], entecavir [ETV], tenofovir [TDF], lamivudine [LAM], adefovir dipivoxil [ADV], and combination therapies of either LDT and ADV or LDT and TDF, followed by best supportive care [BSC]). The second strategy included sequential therapies of individual NUCs: LAM → ADV, ADV → LAM, LDT → ADV, and ETV → ADV, followed by BSC. The analysis included two scenarios: with and without costs due to nephrotoxicity. Renal impact was quantified as costs alone, without consideration for quality of life decrements. RESULTS When renal impact was not considered, without treatment sequencing, LDT was cost effective compared with other NUCs. Amongst the strategies with sequencing, LDT → ADV was cost effective. The results were similar when renal impact was considered. However, LDT strategy demonstrated better cost effectiveness. In probabilistic sensitivity analysis, in both scenarios, LDT → ADV sequence was cost effective with 51 % probability even at willingness to pay of $20,000. CONCLUSION Use of LDT, as compared with other NUCs, is cost effective in CHB treatment in Chinese healthcare settings. Considering the detrimental renal impact, overall costs for all treatment options were increased. However, the increase for LDT was comparatively small.

Efficacy of telbivudine with conditional tenofovir intensification in patients with chronic hepatitis B: results from the 2-year roadmap strategy. Drugs Context 2016; 5:212294.

Abstract
Background: A 2-year roadmap study was conducted to evaluate the efficacy and safety of tenofovir intensification at Week 24 in patients with chronic hepatitis B (CHB) receiving telbivudine. Scope: A prospective multicenter study was conducted in treatment-naive patients with hepatitis B e antigen (HBeAg)-positive CHB. All patients received telbivudine (600 mg/day) until Week 24. Thereafter, patients with detectable hepatitis B virus (HBV) DNA (≥300 copies/mL) were administered tenofovir (300 mg/day) plus telbivudine, and patients with undetectable HBV DNA continued telbivudine monotherapy until Week 104. The primary endpoint was the proportion of patients with undetectable HBV DNA (<300 copies/mL) at Weeks 52 and 104. Findings: A total of 105 patients were enrolled in the trial, of which 100 were eligible for efficacy analysis. Undetectable HBV DNA levels were observed at Week 24 in 55 patients who continued on with telbivudine monotherapy. The remaining 45 patients with detectable HBV DNA received tenofovir add-on therapy. With monotherapy, 100% (55/55) and 94.5% (52/55) of patients achieved HBV DNA <300 copies/mL at Weeks 52 and 104, respectively; the corresponding values for patients with add-on therapy were 84.4% (38/45) and 93.3% (42/45). Overall, undetectable HBV DNA (<300 copies/mL) was found in 93% (93/100) and 94% (94/100) of patients at Weeks 52 and 104, respectively. HBeAg seroconversion rate was 44.4% (44/99) at Week 104 for the overall patient population. One patient in the monotherapy group and six in the intensification group demonstrated HBsAg clearance at Week 104. HBsAg seroconversion was observed in four patients at Week 104, all belonged to the tenofovir intensification group. Eight patients sustained HBsAg loss during a posttreatment follow-up period of 16 weeks. Alanine aminotransferase (ALT) normalization was constant in the telbivudine monotherapy group, whereas a progressive improvement was observed in the tenofovir intensification group. Two patients in the monotherapy and none in the intensification group experienced viral breakthrough by Week 104. There were no reports of myopathy in either group. The mean changes in estimated glomerular filtration rate (eGFR), estimated using the Modification of Diet in Renal Disease (MDRD) formula, from baseline to Week 104 were +6.145 mL/min/1.73 m2 (p=0.0230) and +7.954 mL/min/1.73 m2 (p=0.0154) in the telbivudine monotherapy and tenofovir intensification groups, respectively. The incidence of serious AEs was four in the telbivudine monotherapy and two in the tenofovir intensification group. The main limitation of this study was limited sample size, which made the power of the observation low, and the absence of a comparative subgroup to assess the progression of patients with detectable HBV DNA without treatment intensification. Conclusions: Data from this 2-year roadmap study confirmed that telbivudine with add-on tenofovir was effective and well tolerated in patients with CHB. Telbivudine was associated with an improvement in eGFR from baseline in both the groups.

Abstract
The exact number of patients with chronic kidney disease (CKD) in Asia Pacific is uncertain. In numeric terms, the region is home to the largest population of patients with untreated chronic kidney failure. The climatic, geographic, social, cultural, economic, and environmental diversity within this region is higher than in any other part of the world. Large parts of the region face a climate-related burden of infectious diseases. Infections contribute to the development and progression of CKD and complicate the course of patients with pre-existing CKD (especially those on dialysis therapy or who are immunosuppressed), increase the cost of CKD care, and contribute to mortality and morbidity. Kidney involvement is a feature of several infectious diseases prevalent in Asia Pacific. Examples include malaria, leptospirosis, scrub typhus, tuberculosis, hepatitis B and C virus, dengue hemorrhagic fever, and Hantaan virus infections. The contribution of infection-associated acute kidney injury to the overall burden of CKD has not been evaluated systematically. Research is needed to quantify the impact of infections on kidney health by undertaking prospective studies. Nephrologists need to work with infectious disease research groups and government infection surveillance and control programs.

Abstract
It has been reported that treatment with telbivudine might be associated with a significant improvement of renal function in patients with chronic hepatitis B. To confirm this finding, a systematic literature review was conducted. Four online databases (PubMed, CNKI/FMJS, Ovid and SpringerLink) were searched. Serum creatinine, glomerular filtration rate and estimated glomerular filtration rate changes from baseline to the end of the treatment were analyzed. A total of seven full-text articles and 13 abstracts with sample sizes ranging from 15 to 689 patients fulfilled the selection criteria for review. The results showed that long-term treatment with telbivudine, either as monotherapy or combined with other nucleos(t)ide analogs, can significantly improve renal function in chronic hepatitis B patients, particularly those at high risk of renal impairment.

Abstract
The kidney is involved in a wide range of bacterial, viral, fungal, and parasitic diseases. In most systemic infections, renal involvement is a minor component of the illness, but in some, renal failure may be the presenting feature and the major problem in management. Although individual infectious processes may have a predilection to involve the renal vasculature, glomeruli, interstitium, or collecting systems, a purely anatomic approach to the classification of infectious diseases affecting the kidney is rarely helpful because most infections may involve several different aspects of renal function. In this chapter, a microbiological classification of the organisms affecting the kidney is adopted. Although they are important causes of renal dysfunction in infectious diseases, urinary tract infections and hemolytic uremic syndrome (HUS) are not discussed in detail because they are considered separately in chapters XX and XX, respectively.

Abstract
AIM Aberrant methylation of the promoter, P2, and the first exon, E1, regions of the tumor suppressor gene RASSF1A, have been associated with hepatocellular carcinoma (HCC), albeit with poor specificity. This study analyzed the methylation profiles of P1, P2 and E1 regions of the gene to identify the region of which methylation most specifically corresponds to HCC and to evaluate the potential of this methylated region as a biomarker in urine for HCC screening. METHODS Bisulfite DNA sequencing and quantitative methylation-specific polymerase chain reaction assays were performed to compare methylation of the 56 CpG sites in regions P1, P2 and E1 in DNA isolated from normal, hepatitic, cirrhotic, adjacent non-HCC, and HCC liver tissue and urine samples for the characterization of hypermethylation of the RASSF1A gene as a biomarker for HCC screening. RESULTS In tissue, comparing HCC (n = 120) with cirrhosis and hepatitis together (n = 70), methylation of P1 had an area under the receiver operating characteristics curve (AUROC) of 0.90, whereas methylation of E1 and P2 had AUROC of 0.84 and 0.72, respectively. At 90% sensitivity, specificity for P1 methylation was 72.9% versus 38.6% for E1 and 27.1% for P2. Methylated P1 DNA was detected in urine in association with cirrhosis and HCC. It had a sensitivity of 81.8% for α-fetoprotein negative HCC. CONCLUSION Among the three regions analyzed, methylation of P1 is the most specific for HCC and holds great promise as a DNA marker in urine for screening of cirrhosis and HCC.

Abstract
We have reported a case of occult hepatitis B virus infection (OBI) associated membranous nephropathy (MN) with complete remission under an ongoing 3.5-year entecavir monotherapy. A 59-year-old man with a 3-year history of liver cirrhosis was introduced to our department because of oliguria, proteinuria and microscopic haematuria. He, with negative serum HBV surface antigen, was not detected HBV DNA in his serum. Renal biopsy was performed and was compatible with a diagnosis of hepatitis B virus-related membranous nephropathy (HBV-MN). The patient was prescribed diuretics and intravenous albumin, and his ascites and oedema remitted gradually. At the same time, entecavir 0.5 mg per day was started. Entecavir treatment was continuing for 3.5 years and finally resulted in complete remission of proteinuria. This suggests that entecavir monotherapy may induce and maintain complete remission of MN associated with OBI.

Abstract
BACKGROUND Hepatitis B virus-associated glomerulonephritis (HBV-GN) mainly occurs in children. Patients with HBV-GN are frequently positive for serum HBV surface antigen (HBsAg), but they are rarely negative. OBJECTIVE To explore the clinical and pathological characteristics of patients with HBV-GN who are serum HBsAg negative. STUDY DESIGN Five children with HBV-GN who are negative for HBsAg were included in this study. Their clinical and pathological characteristics were collected and analyzed. RESULTS All 5 children presented with different levels of proteinuria and microscopic hematuria. Renal biopsies showed membranous nephropathy accompanied by HBsAg and/or HBcAg deposits in glomeruli in all of the children. Steroids and/or other immunosuppressants were administered in all cases without antiviral therapy during the early stages of treatment. Two children achieved complete remission but relapsed after the drugs were tapered down. The other 3 children were initially non-responsive but achieved remission after lamivudine was added. CONCLUSIONS Treatment of HBsAg-negative HBV-GN patients with immunosuppressants alone could not achieve satisfactory effects. Antiviral treatment is effective and may be necessary in this type of patient.

Abstract
INTRODUCTION Chronic viral hepatitis represent major health problems worldwide, with an evolution that is sometimes marked by a series of extrahepatic manifestations. Among these, kidney disease may occur, either as glomerulonephritis, and/or renal dysfunction. MATERIAL AND METHODS The purpose of this study was to achieve a complete assessment of the liver and kidney function in a series of patients diagnosed with chronic viral hepatitis, in order to identify a possible kidney disease in this context. 104 patients with chronic viral hepatitis B and C, aged between 25 and 80, were included in the study. These patients were assessed by a series of tests that allowed us to perform a complete evaluation of both liver and kidney function: liver cytolysis enzymes, serum bilirubin, markers of cholestasis, markers of viral infection, urinalysis, albuminuria, electrophoresis of urinary proteins, urea, creatinine, and abdominal ultrasound. RESULTS Glomerular injury was a rare finding in patients with chronic hepatitis. Patients with chronic hepatitis B had glomerular disease in 5,88 % of cases, while 10 % of the patients with hepatitis C presented this type of renal disease. Acute kidney injury was not identified in our patient group. None of the patients in the hepatitis B study group presented chronic kidney disease. CKD was present in two patients with chronic hepatitis C that had no other associated conditions.

Abstract
Cytokines, involved in the T-helper 1 system, play a role in the regulation of hepatitis B virus (HBV) clearance and the immune response to HBV antigens during natural infection or planned vaccination. Our aim was to examine whether the polymorphic variants of IL-12 are equally associated with development of antibodies to HBV surface antigen (anti-HBs) in hemodialysis (HD) patients in the case of HBV vaccination or HBV infection. The IL-12A rs568408 and IL-12B rs3212227 polymorphisms were analyzed in relation to anti-HBs development in 602 HD patients with negative antibodies to HBV core antigen (anti-HBc) who were hepatitis B vaccinated (group I) as well as in 237 anti-HBc positive HD patients who were infected with HBV in the past (group II). In group I, 199 patients did not develop an anti-HBs titre >10 IU/L (subgroup Ia), whereas in group II, 55 patients did not develop an anti-HBs titre >10 IU/L (subgroup IIa). Patients of groups I and II that developed an anti-HBs >10 IU/L were included into subgroups Ib and IIb, respectively. In hepatitis B vaccinated HD patients, development of a protective anti-HBs titre was positively associated with vintage of renal replacement therapy (RRT), chronic glomerulonephritis as a cause of RRT, and GA rs 568408 IL-12A (OR 1.6, 95 % CI 1.0-2.5, P = 0.035), but a frequency distribution of this genotype between responders and non-responders was not significant when the Bonferroni correction was applied. In HBV infected HD patients, anti-HBs development was positively associated with AC rs3212227 IL-12B (OR 8.0, 95 % CI 2.6-24.9, P < 0.001), whereas HBsAg positivity, AA rs3212227 IL-12B (OR 0.3, 95 % CI 0.1-0.7, P = 0.007), and CC rs3212227 IL-12B (OR 0.1, 95 % CI 0.03-0.6, P = 0.011) were negative predictors of positive anti-HBs phenotype. When the Bonferroni correction was applied, if appropriate, these associations remained significant. In HD patients, the studied IL-12 polymorphic variants seem to be associated with the anti-HBs phenotype (a) with borderline significance for IL-12A in hepatitis B vaccinated patients, and (b) significantly for IL-12B in patients who underwent natural HBV infection.

Abstract
BACKGROUND AND OBJECTIVES Clinically, hepatitis B virus (HBV) infection is observed to be associated with nephropathy. However, previous population-based studies failed to show an association between HBV infection and CKD. Therefore, this cross-sectional study was designed to further explore this association. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A representative sample of 6854 Chinese adults aged 30-75 years was tested for levels of serum hepatitis B surface antigen, alanine aminotransferase (ALT), creatinine, urinary albumin/creatinine ratio, and potential CKD risk factors. RESULTS Neither HBV infection nor elevated ALT (ALT+; ≥ sex-specific 90th percentile of ALT levels of noninfected persons) was significantly associated with reduced estimated GFR (eGFR < 60 ml/min per 1.73 m(2)). Compared with noninfected persons, HBV-infected persons with ALT+, but not those with ALT- (P=0.26), were more likely to have reduced eGFR (odds ratio, 4.07; 95% confidence interval, 1.18-14.0; P=0.03). Further analysis with a general linear model revealed a significant difference in eGFR (mean ± SEM) between HBV-infected and noninfected persons (87.8±0.8 versus 90.2±0.4 ml/min per 1.73 m(2); P=0.002). This difference was mainly derived from that between HBV-infected persons with ALT+ and noninfected persons, with an average difference in eGFR of -4.5 (95% confidence interval, -0.9 to -8.1; P=0.01). HBV infection and ALT+, alone or in combination, were not significantly associated with albuminuria or CKD. CONCLUSIONS HBV infection with elevated ALT, rather than HBV infection alone, was associated with reduced renal function.

Abstract
Long-term safety of treatment with hepatitis B virus (HBV) polymerase inhibitors is a concern. Adefovir dipivoxil (ADV) therapy has previously been associated with impairment of renal function. Limited data are available on the safety of combination therapy with nucleos(t)ide analogues and interferon alfa (IFNα). The aim of this analysis was to assess the renal function during combination therapy with peginterferon alfa-2a (PegIFNα-2a) plus ADV vs either drug alone in patients with hepatitis B/D co-infection. We performed a retrospective analysis of renal function data of patients treated in the Hep-Net/International Delta Hepatitis Intervention Trial 1(HIDIT-1-trial), a European multicenter study to investigate the efficacy of 48 weeks of therapy with PegIFNα-2a+ADV vs either drug alone in 90 patients with chronic hepatitis B/D co-infection. Glomerular filtration rates (GFR) were calculated by Cockcroft-Gault (CG), abbreviated Modification of Diet in Renal Disease (MDRD) study and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. After 48 weeks of therapy GFR values were significantly lower in patients receiving adefovir-containing treatment vs PegIFNα-2a alone [mean difference 16.1 mL/min (CG) and 10.2 mL/min (MDRD), respectively, P < 0.05] while no differences were observed between patients receiving adefovir alone vs combination treatment. Twenty-four weeks after treatment GFR values did not differ between treatment arms. A decrease in GFR ≥ 20% was observed more often in patients during adefovir-containing treatment vs PegIFNα-2a alone (P < 0.05) which was confirmed by Kaplan-Meier analysis. Adefovir-containing but not PegIFNα-2a treatment was associated with a decrease in GFR values in about one-fifth of patients. Combination treatment of PegIFNα-2a+ADV in chronic hepatitis B/D co-infection did not lead to any further impairment of kidney function.

Abstract
BACKGROUND The association between chronic hepatitis C virus (HCV) infection and end-stage renal disease (ESRD) has been widely debated. STUDY DESIGN National population-based cohort study. SETTING & PARTICIPANTS Insurance claims data from the Taiwan National Health Insurance Research Database in 2000-2005. PREDICTOR Chronic HCV infection as defined by the International Classification of Diseases, Ninth Revision, Clinical Modification. OUTCOMES ESRD as defined by the International Classification of Diseases, Ninth Revision, Clinical Modification. RESULTS We identified 6,291 adults with chronic HCV infection. The control group included 31,455 sex- and age-matched individuals without evidence of chronic hepatitis. The incidence of ESRD was 2.14-fold higher in patients with chronic HCV infection (HR, 1.53; 95% CI, 1.17-2.01; P = 0.002) than in patients without HCV infection. Age stratification analysis showed that patients aged 50-59 years with chronic HCV infection (HR, 7.77; 95% CI, 4.23-14.3; P < 0.001) had the highest risk of developing ESRD relative to patients aged 20-49 years without chronic HCV infection (interaction P < 0.001). LIMITATIONS Lack of clinical data. CONCLUSIONS Patients with chronic HCV infection are at greater risk of developing ESRD than individuals without chronic HCV infection. In addition, the risk of developing ESRD is highest in younger patients with HCV infection. Early renal screening programs should be initiated for this high-risk group of young individuals with chronic HCV infection.
