Abstract
BACKGROUND HBV-GN is one of the most common secondary kidney diseases in China. Entecavir is a first-line antiviral therapy in patients with HBV-GN. OBJECTIVE This retrospective study explored whether entecavir is effective and safe for the treatment of HBV-GN with renal insufficiency. METHODS We screened patients diagnosed with HBV-GN in The Affiliated Hospital of Qingdao University who had elevated serum creatinine levels. Group 1 (30 patients) was given entecavir as antiviral treatment. Group 2 (28 patients) was treated with ARBs. Changes in renal function and the possible influencing factors were observed, with a mean follow-up duration of 36 months. RESULTS At the end of follow-up, the elevation in the serum creatinine level and reduction in the eGFR were greater in group 1 than in group 2. The overall renal survival rate, using eGFR < 15 ml/min as the primary renal end point, was 96.7% in group 1 and 67.9% in group 2. Urine protein excretion was decreased in both groups. Treatment with entecavir and the remission of proteinuria were protective factors against renal function impairment, while a lower baseline eGFR was a risk factor for progression to ESRD. CONCLUSIONS Entecavir slows the progression of renal function impairment in HBV-GN and exerts a significant renal protective effect.

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.

Kalita D, Deka S, Chamuah K, Ahmed G. Laboratory Evaluation of Hepatitis C Virus Infection in Patients Undergoing Hemodialysis from North East India. J Clin Exp Hepatol 2022; 12:475-482. [PMID: 35535106 PMCID: PMC9077174 DOI: 10.1016/j.jceh.2021.05.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Accepted: 05/30/2021] [Indexed: 02/08/2023] Open
Abstract
INTRODUCTION Subjects undergoing hemodialysis have enhanced vulnerability to hepatitis C virus (HCV) infection due to invasive procedures and poor infection control practices. Early detection and treatment are essential to prevent cross-infection and mortality/morbidity. However, common use anti-HCV antibody tests lack the necessary accuracy, and alternative tests (e.g. core antigen detection kits) which are available need to be examined as a viable alternative. METHOD A total of 270 continuous serum samples were collected from patients undergoing dialysis within 15 months of study period. Sequentially, multiple tests were performed - immunochromatography-based rapid test, third-generation ELISA i.e. (anti-HCV antibody detection), fourth-generation ELISA (HCV antigen-antibody combined detection assay), and HCV RNA quantitative real time polymerase chain reaction (qPCR) assay. Diagnostic parameters of serological kits were compared in terms of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy, and so on. Statistical Package for the Social Sciences was used. RESULTS HCV-combined core antigen-antibody assays performed better than other serological assays in reference to the gold standard HCV RNA. This fourth-generation assay yielded a Kappa value of 0.947 compared with the value of 0.747 and 0.619 for anti-HCV ELISA and rapid detection test. Other parameters such as sensitivity, specificity, PPV, NPV, and so on were also better for fourth-generation ELISA compared with third-generation ELISA and other serological assays. HCV RNA was negative in 7.3% of anti-HCV-positive patients and was detected in 11.4% of anti-HCV ELISA-negative patients. In about 1.6% of HCV RNA-positive cases, fourth-generation ELISA was negative and had low HCV viral load (650 IU/ml and below). Fourth generation ELISA detected additional 7.4% HCV positive cases (compared to third generation kits) and upon cost effective analyis, additional cost to be bear for the better detection (by fourth generation kit) was found to be only INR 27 per 1% increased case detection. CONCLUSION In resource scant setup, screening and follow-up of patients undergoing hemodialysis can be performed by fourth-generation HCV ELISA (antigen-antibody combined assay) instead of the current practice of anti-HCV antibody ELISA. Better yield in detection rate will compensate for slight addition to costs.

Abstract
Background and Aim A low serum prealbumin concentration is common in maintenance hemodialysis patients with hepatitis B and C and may be associated with mortality. In this study, we assessed Department of Nephrology and Hemodialysis predictive value of a low serum prealbumin concentration on mortality in HD patients using reused low-flux dialyzers who were infected with hepatitis B and/or C virus. Methods We used serum prealbumin levels to predict the long-term mortality of 326 hemodialysis patients. The patients were divided into two groups: group 1 (n = 140, with hepatitis B and/or C virus infections), and group 2 (n = 186, without hepatitis virus infections). Results During a 5-year follow-up, there were 75 deaths due to all-cause mortality (23.0%). Mortality was significantly higher (P < 0.001) in patients with hepatitis B and/or C infection (44%) than in those without hepatitis infection (8%). Serum prealbumin was lower in the hepatitis infected group and mortality group than in non-infected group and survival group. Multivariate Cox regression analysis showed that long duration of HD and lower serum prealbumin and albumin were related to mortality in patients undergoing maintenance HD. Receiver operating characteristic curves showed that serum prealbumin had a good prognostic value in predicting mortality in both groups with hepatitis B and/or C virus infection and without hepatitis infection (AUC = 0.792 [95% confidence interval: 0.714-0.87], P < 0.001; cut-off value = 24.5 mg/dl, sensitivity = 62.3%, and specificity = 88.6%). Conclusion In HD patients, serum prealbumin was a good prognostic biomarker of mortality in both groups of patients with hepatitis B and/or C virus infections and without hepatitis infections.

Abstract
Uraemic patients undergoing haemodialysis are at high risk of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. We aimed to evaluate the evolutionary seroprevalence of viral hepatitis and the gap in HCV care cascades in this special population by a large-scale surveillance study in Taiwan. Uraemic patients on maintenance haemodialysis from 22 sites (FORMOSA-LIKE group) in 2012 (n = 1,680) and 2019 (n = 2,326) were recruited for this study. The distributions and sequential changes of viral hepatitis markers were analysed. The prevalence of anti-HCV antibody and hepatitis B surface antigen (HBsAg) seropositivity was 13.6% (316/2326) and 11.5% (267/2326), respectively, in 2019 compared with 17.3% (290/1680, P = .002) and 13.6% (229/1680, P = .046), respectively, in 2012. The HCV-viremic rate among anti-HCV-seropositive patients was significantly lower in 2019 than in 2012 (56.3% [178/316] vs. 73.8% [214/290], P < .001). The HCV treatment rate increased from 2.3% (5/217) in 2012 to 21.7% (49/226) in 2019 (P < .001). In the sequential analysis of the 490 patients who participated in both screens, 17 of the 55 HCV-viremic patients became HCV RNA seronegative, including 13 by antivirals and four spontaneously. By contrast, one anti-HCV-seropositive but nonviremic patient became viremic, and six anti-HCV-seronegative patients became anti-HCV-seropositive in 2019. The annual incidence of new HCV was 0.2%/year. Seven HBsAg-seropositive patients experienced HBsAg loss (1.25%/year). Two patients had new anti-HBc seropositivity (new HBV exposure: 0.57%/year). The seroprevalence of viral hepatitis decreased in an 8-year follow-up but remained prevalent, and the treatment of HCV infection was underutilized in uraemic patients. Additional efforts are needed to enhance the HCV treatment uptake of uraemic patients. Clinical Trial IDs: NCT03803410, NCT01766895.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is the most common hepatotropic viral infection affecting the patients on maintenance hemodialysis. Treatment of chronic HCV infection in stage 4 and 5 CKD includes a combination of elbasvir/grazoprevir and glecaprevir/pibrentasvir, which are not available in many countries. OBJECTIVE Hence, we have conducted this study to look for the safety and efficacy of sofosbuvir combination therapy in this difficult to treat population. METHODS We conducted a single-center, prospective, open-label study in which Stage 5 CKD patients on maintenance hemodialysis with HCV infection. Total of 18 patients was included. sofosbuvir with daclatasvir or ledipasvir was used according to genotype for 12 weeks. HCV RNA, genotype, transient elastography (TE) was considered for every patient. HCV RNA was quantified at 4th week, 12th week and 12 weeks post-treatment to look for sustained virologic response (SVR 12). RESULTS Infection due to genotype 1 was seen in 12 (66.7%) patients followed by genotype 3 in 4 (22.3%) with each patient of genotype 2 and 5. The median value of HCV RNA was 2,35,000 IU/mL. On TE, all had liver stiffness of <9.4 KPa. All patients had HCV RNA of <15 IU/mL at 4th and 12th week of treatment and 12 weeks post-treatment. No significant change in hemoglobin, eGFR and liver stiffness was observed. CONCLUSION Full dose sofosbuvir i.e. 400 mg, in combination with NS5A inhibitors daclatasvir or ledipasvir is found to be safe and effective in patients with end stage renal disease, who are on maintenance hemodialysis.

Abstract
Purpose Baseline viral load and existence of resistance-associated substitutions (RASs) are associated with direct-acting antiviral agent (DAA) treatment failure in patients with chronic hepatitis C virus (HCV) infection. Patients and methods This study was done on HCV-infected patients with different clinical conditions, group 1 included HCV-infected patients with only liver disease (n= 24) and group 2 had HCV-infected patients with coexisting chronic kidney disease (CKD) (n =26). Baseline RAS in the viral genome, before treatment initiation, was examined in both the groups to understand the host disease status on their occurrence. Results Predominant genotype (gt) differed in both the groups, in group 1 it was gt3 while it was gt1 in group 2. Overall, the occurrence of RASs at baseline was seen in 10 patients (20%); in group 1 it was seen in 8 (33.3%) as compared to only 2 (7.6%) in group 2; p < 0.001. RAS in both NS5a and NS5b regions of the virus was seen in group 1 while in group 2, RASs were seen only in the NS5a region of the virus at 30K position. In group 1, multiple RASs were also seen. The existence of RAS at baseline in both the groups did not affect the attainment of post-treatment cure for the virus in terms of sustained virological response (SVR). Conclusion Host disease status influences the occurrence of baseline RAS in the virus.

Abstract
With increasing prevalence, chronic kidney disease (CKD) has become a global health problem. Due to the retention of uremic toxins, electrolytes and water, and the resultant metabolic disturbances, CKD affects several organs, including the nervous system. Thus, CKD patients suffer from several neurological complications, including dementia, cognitive impairment, motor abnormalities, depression, and mood and sleep disturbances. However, the mechanisms underlying the neurological complications are least elucidated. We have recently reported a highly reproducible mice model of CKD induced by high adenine diet, which exhibited psychomotor behavioral abnormalities and blood-brain barrier disruption. In the present study, using the mice model, we have investigated psycho-motor and cognitive behaviour, and the neurochemical and histopathological alterations in brain relevant to the observed behavioural abnormalities. The results demonstrate global loss of Acetylcholinesterase activity, and decrease in neuronal arborisation and dendritic spine density in discrete brain regions, of the CKD mice. Oxidative stress, inflammation, and mitochondrial dysfunctions were found in specific brain regions of the mice, which have been regarded as the underlying causes of the observed neurochemical and histopathological alterations. Thus, the present study is of immense importance, and has therapeutic implications in the management of CKD-associated neurological complications.

Duong MC, McLaws ML. Screening haemodialysis patients for hepatitis C in Vietnam: The inconsistency between common hepatitis C virus serological and virological tests. J Viral Hepat 2019; 26:25-29.

Abstract
Selecting the appropriate screening method and interval for the early detection of hepatitis C virus (HCV) infection in low-resourced haemodialysis settings is a challenge. The challenge occurs when patients are classified as HCV-RNA positive but negative to HCV-core antigen (HCV-coreAg), anti-HCV and genotyping tests. We aim to clarify the inconsistency between HCV-RNA, HCV-coreAg, anti-HCV and HCV genotyping tests in haemodialysis patients and determine the reliability of HCV-coreAg as a routine two-monthly screening strategy. Haemodialysis patients were tested every 2 months between 2012 and 2014 at the largest district haemodialysis unit in Ho Chi Minh City, Vietnam, for aminotransferases, anti-HCV antibodies, HCV-coreAg, HCV-RNA and HCV genotype. HCV-coreAg and anti-HCV results were tested against HCV-RNA for sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV). All 201 patients participated in the study. The HCV-coreAg test performed better than the anti-HCV test for sensitivity (100% vs 31%), NPV (100% vs 90%) and accuracy (100% vs 90%). The HCV-coreAg and anti-HCV tests performed no differently for specificity (100% and 98%, respectively) or PPV (100% and 73%, respectively). Kappa values for HCV-coreAg and anti-HCV tests were 1 and 0.39, respectively. Early detection of HCV for the purpose of infection prevention requires a high level of sensitivity and HCV-coreAg performed better in our chronic haemodialysis population as a two-monthly screening method than routine anti-HCV testing. HCV-coreAg test is less labour-intensive with a higher level of accuracy in patients with low viral loads making it cost effective for low-resourced settings. Repeating genotyping may be required in HCV-coreAg positive patients with a low viral load.

Abstract
INTRODUCTION Hepatitis C virus (HCV) infection in end stage renal disease (ESRD) is associated with increased mortality. Recently, numerous directly acting antiviral agents have been approved for the management of HCV. Ledipasvir along with Sofosbuvir has been approved for management of genotype 1 infection in patients with eGFR ≥30 mL/min. However, there is paucity of data regarding its role in the management of patients on dialysis. MATERIAL AND METHODS This is a single center prospective open label observational study to assess the safety and efficacy of Ledipasvir and Sofosbuvir in hemodialysis (HD) patients who were diagnosed with HCV genotype 1 infection. Eligibility criteria were treatment naive HD patients with normal liver histology. We administered Ledipasvir and Sofosbuvir combination tablet on alternate days for a period of 12 weeks. Primary efficacy end point was the assessment of sustained virological response (SVR12), and the safety end point was the discontinuation of therapy secondary to adverse drug effects. RESULTS A total of 21 patients were treated with this regimen. Two patients expired during the study period and are not related to the therapy. SVR12 was achieved in all the 19 patients. None of the patients in our study discontinued the therapy or had severe adverse drug effects. One patient had head ache and another patient had giddiness which were managed symptomatically. CONCLUSION Ledipasvir and Sofosbuvir combination therapy on alternate days, is effective even in ESRD patients, with excellent SVR12 rates, and it is as safe as in other population groups, without any major adverse reactions.

Abstract
BACKGROUND Disease-related malnutrition is highly prevalent, and has prognostic implications for patients with chronic kidney disease (CKD); however, few studies have investigated the impact of malnutrition, or protein-energy wasting (PEW), on healthcare utilization and medical expenditure among CKD patients. METHODS Using claim data from the National Health Insurance in Taiwan, this study identified patients with CKD between 2009-2013 and categorized them into those with mild, moderate, or severe CKD. Cases with PEW after CKD was diagnosed were propensity-score matched with controls in a 1:4 ratio. Healthcare resource utilization metrics were compared, including outpatient and emergency department visits, frequency and duration of hospitalization, and the cumulative costs associated with different CKD severity. RESULTS From among 347,501 CKD patients, eligible cohorts of 66,872 with mild CKD (49.2%), 27,122 with moderate CKD (19.9%), and 42,013 with severe CKD (30.9%) were selected. Malnourished CKD patients had significantly higher rates of hospitalization (p < .001 for all severities) and re-admission (p = .015 for mild CKD, p = .002 for severe CKD) than non-malnourished controls. Cumulative medical costs for outpatient and emergency visits, and hospitalization, were significantly higher among all malnourished CKD patients than non-malnourished ones (p < .001); total medical costs were also higher among malnourished patients with mild (62.9%), moderate (59.6%), or severe (43.6%) CKD compared to non-malnourished patients (p < .001). CONCLUSIONS In a nationally-representative cohort, CKD patients with PEW had significantly more healthcare resource utilization and higher aggregate medical costs than those without, across the spectrum of CKD: preventing PEW in CKD patients should receive high priority if we would like to reduce medical costs.

Abstract
Hepatitis C virus (HCV) infection is highly prevalent among patients treated with maintenance hemodialysis and is an important cause of morbidity and mortality. It is necessary to determine the HCV genotype and the viral load to monitor the clinical and laboratory features and to establish an optimal antiviral treatment strategy. Antiviral treatments are presented with a standard interferon-based regimen and new direct-acting antiviral agents. The advent of direct-acting antivirals has improved the efficacy and safety of HCV treatment for most patients, even in difficult-to-treat populations such as patients on hemodialysis. HCV treatment with direct-acting antivirals in hemodialysis patients is highly effective, with viral eradication rates similar to those seen in patients without chronic kidney disease and with acceptable adverse event profiles.

Abstract
Abstract
The objective of this study was to reveal the likely genomic instability in children with chronic kidney disease (CKD) using micronucleus (MN) assay on buccal epithelial cells (BEC). We investigated the frequencies of micronuclei and other nuclear anomalies, such as nuclear buds, binucleated cells, condensed chromatin, and karyorrhectic and pyknotic cells in BEC. Children with CKD were grouped as follows: children in the pre-dialysis (PreD) stage (N=17), children on regular haemodialysis (HD) (N=14), and children who have undergone transplantation (Tx) (N=17). As a control group, twenty age- and gender-matched healthy children were selected. The MN frequency in BEC of all groups of children with CKD was significantly elevated (5- to 7-fold) as compared to the control group (p<0.001). In contrast, the frequencies of nuclear buds were not significantly higher in the study groups compared to the control group. The frequencies of binucleated cells and condensed chromatin cells were significantly higher in all subgroups of children with CKD relative to the control group (p<0.001). Our results show that the BEC of pediatric PreD, HD, and Tx patients with CKD display increased cytogenetic, cytokinetic, and cytotoxic effects. They also point to the sensitivity and usefulness of the BEC MN assay in the assessment of genetic susceptibility of patients with CKD.

Abstract
Data regarding the risk of various liver diseases among different hepatitis viruses in kidney transplantation have not yet been identified.We selected individuals with kidney transplantation (ICD-9-CM V420 or 996.81) from 2000–2009 from the catastrophic illness registry of National Health Insurance Research Database (NHIRD)as the study cohort. The two end-points in the study included overall death, and post-transplant occurrence of hepatic disease. After adjustment for other risk factors, the risk of mortality was increased in patients with HBV infection (N = 352) and with HCV infection (N = 275) compared to those with neither HBV nor HCV infection (N = 3485). In addition,renal transplant recipients with HBV alone,HCV alone, and both with HBV and HCVinfectionrespectively had an approximately 10-fold hazard ratio (HR) = 9.84, 95% confidence interval (CI): 4.61–21.0, 4-fold increased risk (HR = 4.40, 95% CI: 1.85–10.5)and 5-fold increased risk (HR = 4.63, 95% CI: 1.06–20.2)of hepatocellular carcinoma (HCC)compared to those with neither HBV nor HCV infection. Our findings showed a significant risk of de novo liver disease in recipients with hepatitis virus infection. Based on our findings, we reinforce the importance and impact of hepatitis virus in renal transplantation.

Abstract
We have read the case report of Nihon-Yanagi et al. The patient they described developed hepatic granuloma two times and the granulomatous lesion was surrounding metal staples/clips suggesting that the granuloma was due to surgical staples/clips. Hepatic granulomas (HGs) are reported in around 5 % of patient who undergo a liver biopsy and caused by several diseases including sarcoidosis, tuberculosis, hydatid cyst, brucellosis, typhoid fever, chronic hepatitis B and C and primary biliary cirrhosis (PBC). Chronic hepatitis B and C infections are the most common and serious causes of liver damage in patient with renal failure. Their prevalence is a higher than people without renal failure. We have previously reported that the prevalences of HGs in patients with chronic hepatitis B and C are 1.5 and 1.3 % respectively. The described patient was on hemodialysis for 12 years. The other causes of HG seem excluded; however hepatitis B and C infections and PBC should have been tested and excluded before ascribing the HGs to surgical staples/clipping material.

Abstract
The role of infection with hepatitis B virus (HBV) and hepatitis C virus (HCV) in terms of survival among dialysis patients remains incompletely understood. In the present multicenter prospective cohort study, we investigated the prevalences of HBV and HCV infection among 3,321 patients receiving maintenance dialysis in Korea, and assessed the impacts of these infections on survival. All included patients underwent hepatitis B antigen (HBsAg) and HCV antibody (Ab) testing, which revealed that 236 patients (7.1%) were HBsAg-positive, and 123 patients (3.7%) were HCV Ab-positive. HBsAg-positive and HCV Ab-positive patients were matched to hepatitis virus-negative patients using a propensity score at a ratio of 1:2. The prevalences of HBV and HCV infection did not significantly differ according to dialysis modality. Linear-by-linear association analysis revealed that hepatitis B prevalence significantly increased with increasing dialysis vintage (p = 0.001), and hepatitis C prevalence tended to be higher with increasing dialysis vintage (p = 0.074). We compared the survival of HBsAg-positive and HCV Ab-positive patients to that of hepatitis virus-negative patients. After propensity score matching, cumulative survival did not differ between HBsAg-positive and HBsAg-negative patients (p = 0.37), while HCV Ab-positive patients showed significantly lower survival than HCV Ab-negative patients (p = 0.03). The main conclusions of the present study are that HBV infection prevalence increased with longer dialysis vintage, and that both HBV and HCV infections were most prevalent among patients with the longest dialysis vintage. Additionally, HCV infection among maintenance dialysis patients is associated with an increased risk of mortality.

Abstract
In coinfected HBV/HCV patients, HBV replication is usually suppressed by HCV over the time. No study to date has evaluated the HBV viremia in long-term follow-up after HCV treatment in hemodialysis patients with HBV/HCV coinfection. This study aimed to assess the evolution of HBV viremia after HCV treatment in this special population. Ten hemodialysis patients with HBV/HCV coinfection with dominant HCV infection (HBV lower than 2000 IU/mL) and significant fibrosis were treated with interferon-alpha 3 MU 3×/week for 12 months and could be followed for at least 36 months after HCV treatment. Six cases of HBV reactivation (60%) during follow-up were observed and 5/6 had been successfully treated for HCV. Patients with HBV reactivation received anti-HBV therapy. Our preliminary findings indicate that treatment of hepatitis C in HBV/HCV coinfected hemodialysis patients may favor HBV reactivation. Thus, continued monitoring of HBV viremia must be recommended and prompt anti-HBV therapy should be implemented.

Abstract
Hepatitis C virus (HCV) infection is highly prevalent among chronic kidney disease (CKD) subjects under hemodialysis and in kidney transplantation (KT) recipients, being an important cause of morbidity and mortality in these patients. The vast majority of HCV chronic infections in the hemodialysis setting are currently attributable to nosocomial transmission. Acute and chronic hepatitis C exhibits distinct clinical and laboratorial features, which can impact on management and treatment decisions. In hemodialysis subjects, acute infections are usually asymptomatic and anicteric; since spontaneous viral clearance is very uncommon in this context, acute infections should be treated as soon as possible. In KT recipients, the occurrence of acute hepatitis C can have a more severe course, with a rapid progression of liver fibrosis. In these patients, it is recommended to use pegylated interferon (PEG-IFN) in combination with ribavirin, with doses adjusted according to estimated glomerular filtration rate. There is no evidence suggesting that chronic hepatitis C exhibits a more aggressive course in CKD subjects under conservative management. In these subjects, indication of treatment with PEG-IFN plus ribavirin relies on the CKD stage, rate of progression of renal dysfunction and the possibility of a preemptive transplant. HCV infection has been associated with both liver disease-related deaths and cardiovascular mortality in hemodialysis patients. Among those individuals, low HCV viral loads and the phenomenon of intermittent HCV viremia are often observed, and sequential HCV RNA monitoring is needed. Despite the poor tolerability and suboptimal efficacy of antiviral therapy in CKD patients, many patients can achieve sustained virological response, which improve patient and graft outcomes. Hepatitis C eradication before KT theoretically improves survival and reduces the occurrence of chronic graft nephropathy, de novo glomerulonephritis and post-transplant diabetes mellitus.

Discrepancy between serological and virological analysis of viral hepatitis in hemodialysis patients. Int J Med Sci 2014; 11:436-41. [PMID: 24688305 PMCID: PMC3970094 DOI: 10.7150/ijms.8265] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2013] [Accepted: 02/18/2014] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND AND AIM Viral hepatitis is a health threat for hemodialysis (HD) patients and it may be transmitted during treatment. Some patients categorized to have viral hepatitis were found to be non-viremic. To clarify the discrepancy between the serological tests in HD patients, we conducted the study. METHODS A total of 1681 HD patients was included. Blood samples were analyzed for hepatitis B surface antigen (HBsAg) and anti-hepatitis C antibody (anti-HCV). Detection of hepatitis B virus (HBV) DNA and hepatitis C virus (HCV) RNA were performed in either HBsAg (+) or anti-HCV (+) samples. HBV DNA/HCV RNA was also measured in a subset of HBsAg (-) and anti-HCV (-) patients. Liver function tests were analyzed and compared with the serological and virological tests. RESULTS The serological tests showed that 230 patients (13.7%) were HBsAg (+) and 290 (17.3%) were anti-HCV (+). We were unable to detect HBV DNA in 97 of 230 (42.2%) HBsAg (+) patients, and HCV RNA could not be found in 76 of 290 (26.2%) anti-HCV (+) patients. In 167 HBsAg (-) patients, only one showed a trace amount of HBV DNA. None of 151 anti-HCV (-) patients showed detectable HCV RNA. The prevalence rate of viral hepatitis remains high in Taiwanese HD patients: 13.7% for HBV and 17.3% for HCV. However, virological analysis showed 42.2% non-viremic rate for HBsAg and 26.2% non-viremic rate for anti-HCV. CONCLUSIONS The findings might challenge the presently suggested principles of bed and machine dedication and the diagnosis of viral hepatitis in HD patients.

Abstract
BACKGROUND There are surprisingly a few studies that evaluate the impact of chronic viral hepatitis, which is common in HD (hemodialysis) patients, on HRQOL (health related quality of life). OBJECTIVES We conducted a study to evaluate the impact of chronic viral hepatitis on HRQOL and to compare their HRQOL with non-infected HD patients via a HRQOL questionnaire. PATIENTS AND METHODS The Iranian adapted version of the Kidney Disease Quality of Life Short Form (KDQOL-SF) version 1.3 questionnaires were filled out by the HD patients. In all HD patients, serum HBsAg, HBS Abs, and HCV Abs [enzyme-linked immunosorbant assay (ELISA)] were routinely checked every six months. Patients were considered to have chronic HBV infection if HBsAg was positive for more than six months. In all HD patients, third generation assay was used to detect HCV infection. Furthermore, serum HCV-RNA (PCR) was examined in anti-HCV-positive patients for confirmation of HCV infection. RESULTS in this cross sectional study 4101 patients from 103 dialysis units in Iran between October 2010 and August 2011 were included. Prevalence of hepatitis B and hepatitis C infection was 2.1% and 1.3% respectively. Almost all KDQOL items for viral hepatitis patients had equivalent or better scores than those without viral hepatitis. In the logistic regression after adjustment for age, sex, educational level, marital status, dialysis vintage, HBs Ag positivity and HCV Ab positivity, only age (P < 0.001) and educational level (P = 0.015) had negative impact on quality of life. CONCLUSIONS Our data show that not only general health and physical activity were preserved but also health perception may be better among HD patients with viral hepatitis.

Abstract
Renal amyloidosis is a detrimental disease caused by the deposition of amyloid fibrils. A child with renal amyloidosis may present with proteinuria or nephrotic syndrome. Chronic renal failure may follow. Amyloid fibrils may deposit in other organs as well. The diagnosis is through the typical appearance on histopathology. Although chronic infections and chronic inflammatory diseases used to be the causes of secondary amyloidosis in children, the most frequent cause is now autoinflammatory diseases. Among this group of diseases, the most frequent one throughout the world is familial Mediterranean fever (FMF). FMF is typically characterized by attacks of clinical inflammation in the form of fever and serositis and high acute-phase reactants. Persisting inflammation in inadequately treated disease is associated with the development of secondary amyloidosis. The main treatment is colchicine. A number of other monogenic autoinflammatory diseases have also been identified. Among them cryopyrin-associated periodic syndrome (CAPS) is outstanding with its clinical features and the predilection to develop secondary amyloidosis in untreated cases. The treatment of secondary amyloidosis mainly depends on the treatment of the disease. However, a number of new treatments for amyloid per se are in the pipeline.

Abstract
Chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection in potential kidney transplant candidates-once considered absolute contraindications to kidney transplantation-no longer creates overt barriers to transplantation. Advances in the medical management of HBV and HCV infection have created opportunities for a substantial number of patients to be effectively treated with antiviral therapy before transplantation. For HBV infection, a number of new drugs enable clearance of the virus with minimal adverse effects and drug resistance. Pretransplantation antiviral therapy is advisable for patients with HCV infection, but adverse effects are common and viral eradication remains challenging. Regardless of viral clearance, pretransplant patients without bridging fibrosis (as confirmed by liver biopsy) or clinical stigmata of cirrhosis should be considered for kidney transplantation as survival is superior when compared to treatment with dialysis, and progression of liver disease is unlikely. For patients with advanced liver disease, simultaneous liver-kidney transplantation is an important consideration. These treatment advances further increase the burden of organ donor shortage; however, organs from deceased donors with chronic HBV or HCV infection could be efficiently allocated to certain individuals with a viral infection of the same type to increase the pool of available transplant organs.

Treatment of chronic hepatitis C virus infection in dialysis patients: an update. HEPATITIS RESEARCH AND TREATMENT 2010; 2010:267412.

Abstract
Hepatitis C virus (HCV) infection is a blood-borne infection and its prevalence used to be elevated in hemodialysis (HD) patients. Its main mode of contamination relies on nosocomial transmission. HCV infection is frequently associated in HD patients with normal liver enzymes whereas liver histology can display some degree of HCV-related lesions. The assessment of HCV-related lesions, even in HD dialysis patients, can be done via noninvasive tests. After kidney transplantation, HCV-related lesions can worsen; however, in this setting antiviral treatment harbors the risk of acute rejection. Therefore, it is recommended to implement antiviral treatment while the patient is receiving dialysis therapy. In this setting, the rate of viral clearance is usually high. In case of sustained virological response, no relapse occurs after kidney transplantation, despite heavy immunosuppression.

Abstract
Gastrointestinal complications are known to commonly occur in patients with renal failure. Uremia and dialysis have long been speculated to increase the risk of lesions in the gastrointestinal tract and accessory organs. In addition, gastrointestinal procedures such as gastrointestinal bypass surgery and the administration of colonoscopy preparations can lead to the development of renal complications. Results from studies that have attempted to define the association between renal dysfunction and gastrointestinal complications are, however, conflicting and limited by small and varied sample populations. No clear management guidelines currently exist for many of the gastrointestinal problems that accompany renal failure. This Review examines the existing data on gastrointestinal complications in patients with chronic kidney disease and end-stage renal disease and aims to outline the etiology and management of common gastrointestinal disorders in such patients.
