Int Urol Nephrol 2024; 56:217-222. [PMID: 37209238 PMCID: PMC10776497 DOI: 10.1007/s11255-023-03621-1] [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: 03/12/2023] [Accepted: 04/30/2023] [Indexed: 05/22/2023]
Abstract
PURPOSE Hepatitis C virus infection is a major health problem in hemodialysis patients. Occult HCV infection is defined as the presence of HCV-RNA in hepatocytes or peripheral blood mononuclear cells without the detection of HCV-RNA in the serum. We aimed to evaluate the prevalence and predictors of occult HCV infection among hemodialysis patients after treatment with direct-acting antiviral agents. METHODS This research is a cross-sectional study that included 60 HCV patients maintained on regular HD patients who achieved 24 weeks of sustained virological response after treatment with direct-acting antiviral agents. Real-time PCR was performed to detect HCV-RNA in peripheral blood mononuclear cells. RESULTS HCV-RNA was detected in peripheral blood mononuclear cells of three patients (5%). Occult HCV infection cases were treated by Interferon/ribavirin before direct-acting antiviral agents and two of them had raised pre-treatment alanine aminotransferase levels. Logistic regression analyses revealed that high pre-treatment viral load and raised pre-treatment alanine aminotransferase were associated with an increased risk of occult HCV infection with p value of 0.041 and 0.029, respectively. CONCLUSIONS Occult HCV infection in hemodialysis patients who achieved sustained virological response after treatment with direct-acting antiviral agents may occur, and this may necessitate dual testing for HCV in both serum and peripheral blood mononuclear cells to ensure viral clearance. CLINICAL TRIALS REGISTRATION ClinicalTrials.gov NCT04719338.

Abstract
Anemia is a common consequence of chronic kidney disease (CKD) that is linked to a decrease in patients' quality of life, a rise in morbidity and mortality, and an acceleration in CKD progression. This study aimed to investigate the hematological profile of chronic renal patients undergoing hemodialysis and to correlate the same with anemia. Fifty (54% males and 46% females) with ages ranging from 18-76 years of patients with CKD and on regular maintenance hemodialysis not less than three months at the Iraqi center for dialysis in Baghdad teaching hospital, and 30 healthy adults were recruited into the study. Hemoglobin concentration, red cell count, white blood cell count, platelet count, ESR, CRP and HCV were assessed for the subjects and controls. Results were analyzed using a t-test independent, and the data were retrieved from the laboratory information system in the hospital. Red blood cell count was reduced in nearly all (96%) of the study patients, while ESR was elevated in (98%) and CRP was elevated in (95%). All patients suffered anemia in HD patients. Most of the patients' WBCs and platelet counts were normal. Anti-HCV antibodies were positive in 15 (30%) of these patients, with non-significant differences in both genders. The study concludes that anemia is a significant comorbidity in hemodialysis patients, with several factors contributing to it, and thorough workup and successful treatment of anemia are essential in this group of patients.

Abstract
Abstract: Viral hepatitis (Hepatitis B Virus (HBV) & Hepatitis C Virus (HCV)) related liver disease is a leading cause of morbidity and mortality especially in the patients with advanced renal failure who are treated with dialysis, and this is due to high number of blood transfusion sessions and/or cross contamination from the dialysis circuits. Aims & Objectives: This study aimed to determine the prevalence of HBV and HCV infections in patients with advanced renal failure (ARF). Materials & Methods: A cross-sectional study was done in joint collaboration of Department of Nephrology and Department of Gastroenterology, KGMU, Lucknow, from June 2018 to June 2020 among, CRF patients. Clinical data such as age, gender, duration of dialysis; number of transfusions, Serum sample was collected from each patient. Serological markers for HBV and HCV were determined with ELISA by using commercial diagnostic kits. HCV-RNA and HBV-DNA were determined quantitatively by polymerase chain reaction (PCR) assay. Results: A total 934 patients with advanced renal failure attended the nephrology OPD. Out of 934 patients, 65 (6.96%) patients screened positive for HBV/HCV infection. The results of this study also showed that the prevalence of viral hepatitis infection in the haemodialysis (HD) and without HD patients is 8.25% and 6.3% respectively. Conclusion: It has been found that viral infections, particularly HBV and HCV infections are common in advanced renal failure patients who are on HD.

Abstract
BACKGROUND The worldwide burden of HCV infection among hemodialysis patients has not been systematically examined. METHODS A systematic literature search was conducted in MEDLINE and Scopus to determine the worldwide prevalence of HCV infection, risk factors, and clinical outcomes among hemodialysis patients. Random-effect models and meta-regressions were used to generate pooled estimates and assess heterogeneity. RESULTS Four hundred and seven studies with 1,302,167 participants were analyzed. The pooled prevalence of HCV infection was 21%. The highest prevalence was observed in Africa (28%) and low-income countries (48.5%). A significant prevalence decline was observed following the publication year and was also inversely related to GDP and total population of each country. Factors associated with HCV positivity included younger age, longer dialysis duration, more blood transfusions, and dialyzer reuse. The pooled unadjusted hazard ratio for all-cause mortality was 1.12 (95% CI 1.03-1.22), and the adjusted hazard ratio was 1.21 (95% CI 1.12-1.30) in HCV-infected compared to non-HCV infected patients. CONCLUSIONS HCV infection among hemodialysis patients is a worldwide shared burden and is associated with a higher risk of death. Avoiding unnecessary blood transfusion and dialyzer reuse should be encouraged to prevent HCV transmission in hemodialysis units.

Abstract
BACKGROUND: Due to the rise in the number of deaths, the hepatitis C virus remains a public health issue worldwide. During the recovery period, cytokines are known as indicators of chronic liver infection.
AIM: In this study, immunological parameters were measured and calculated in chronic hemodialysis patients after more than 6 months of drug administration.
METHODS: We have picked 60 patients with hemodialysis who are anti-HCV positive. ELISA and the calculation of alkaline phosphatase (ALP) were used to evaluate IP-10 and IFN-γ.
RESULTS: A substantial association between variables and infected cases was found. No worth was considered for genders or age categories.
CONCLUSIONS: The serum IP-10 level can be a warning primarily for patients who have taken a variety of prescriptions intermittently. In both the RPT and RST cohorts, IFN-γ serum levels are usually elevated. Serum level ALP is not a particular chronic HCV predictor.

Abstract
Background: Kidney transplant (KT) recipients have a high rate of hepatitis C virus (HCV) infection, which can impact long-term graft and patient survival rates. Although direct-acting antivirals (DAAs) are effective for treating HCV, there is limited data on their use in post-KT patients with HCV genotype 4 infection. Objectives: To evaluate the effectiveness and occurrence of adverse events with grazoprevir/elbasvir combination treatment without ribavirin in post-KT patients with HCV genotype 4 infection. Methods: In this case series, nine therapy-naïve adult post-KT patients with HCV genotype 4 infection were recruited. They had stable graft function and received a fixed dose of grazoprevir/elbasvir (50 mg/100 mg) combination without ribavirin daily for 12 weeks. Patients co-infected with hepatitis B virus, HIV, or with evidence of decompensated liver disease were excluded from the study. Patients were monitored for viral load, laboratory values, and adverse events associated with drug treatment. The response was defined by the sustained virologic response at 12 weeks (SVR12) after the end of treatment. Results: All nine patients completed the treatment period and achieved SVR12 with no treatment failure or relapse. Of them, six patients had HCV genotype 4 infection alone, and three had HCV of mixed genotypes 1 and 4. Two (22%) patients showed a rapid HCV clearance at four weeks. No adverse events or serious adverse events were reported. The patients’ renal function was stable during and after the treatment with no deterioration of graft function, and no adjustments to the immunosuppressive therapy were required. Conclusions: Grazoprevir/elbasvir combination without ribavirin is an effective and safe treatment option for post-KT patients with genotype 4 HCV infection.

Abstract
Introduction HCV infection in patients under hemodialysis for end stage chronic kidney disease (ESCKD) may exist despite the absence of anti-HCV antibodies. Molecular methods are widely accepted as "gold standard" techniques for the detection of viral RNA. However, the molecular methods are more expensive in comparison to conventional methods and their replacement is not cost-effective. The aim of this study was to estimate the prevalence of HCV RNA positivity in anti-HCV negative hemodialysis patients and evaluate new diagnostic methods for the detection and the monitoring of hepatitis C in ESCKD patients. Methods The study was performed in four hospitals of Thrace region of Greece and 233 patients with no history of hepatitis C were enrolled. Measurement of anti-HCV antibodies and HCV core antigen was performed by microparticle chemiluminescence immunoassay. Molecular detection of viral RNA was performed by the real-time RT PCR. Results The mean age of the patients was 64.9 ± 23.3 years. HCV-Ag was positive in 2/233 patients (0.86%). Nevertheless, viral RNA was negative in those patients. Conclusions The results of the present study showed that the incidence of HCV-RNA in patients with negative anti-HCV Abs, in hemodialysis patients in Thrace region of Greece was negligible (0/233).

Abstract
BACKGROUND Via hemodialysis, viral infections can be transmitted in patients a new definition of this infection with no increase in liver enzymes, negative HCV-PCR in serum and presence of virus in the liver and peripheral blood mononuclear cell (PBMC) called occult hepatitis C virus (HCV) infection (OCI). We decided to examine the prevalence of occult hepatitis C infection on hemodialysis cases. METHODS The current research is a cross-sectional study on patients with end-stage renal disease (ESRD) who were at three hemodialysis centers in Mazandaran province in Iran during 2012-2014. In this study of 356 patients who were undergoing hemodialysis, 54 patients were excluded due to positive HCV Ab, and the remaining 302 patients were enrolled. The test of all serum samples for HCV-RNA detection of plasma and PBMCs was done by real-time polymerase chain reaction (real-time PCR). RESULTS There was a significant association between the duration of dialysis with the prevalence of occult HCV infection (P=0.017). Eight (2.65%) patients were positive for HBs Ag and with OCI, but none of them was infected with both hepatitis C and B obviously. Also among the total number of patients, nine patients tested positive for HCV RT-PCR in PBMC in which one of them was positive for serum HCV RNA PCR and was excluded from the study. CONCLUSION The results showed that eight patients had an OCI. There was not any association found between age and sex with OCI, but there was a significant relationship between the duration of dialysis with the prevalence of OCI.

Abstract
The aim of this study was to investigate the prevalence of occult hepatitis C virus (HCV) infection (OCI) among HD patients. Blood samples were taken from 79 HD patients and their sera were evaluated for the presence of anti-HCV. Both the sera and peripheral blood mononuclear cells (PBMCs) were then checked for HCV RNA by nested reverse transcriptase-polymerase chain reaction. Anti-HCV was positive among 4/79 (5.1%) of the patients. From 75 patients who were negative for anti-HCV, 71 (94.7%) patients were also negative for HCV RNA in sera samples but five of them were positive for HCV RNA in PBMCs. Totally, out of 79 patients, HCV RNA was detected in PBMCs of five (6.3%) patients, indicating that these patients had OCI. No significant difference was observed between the frequency of OCI and gender (P-value = .6). HCV genotype in all five cases of OCI was genotype 3a. Our study showed prevalence rate of 6.3% OCI infection in HD patients. Regarding the serious complications and the clinical importance of OCI in HD patients, sensitive diagnostic methods for identifying HCV RNA in the PBMCs should be implemented for all HD patients.

Abstract
BACKGROUNDS Hepcidin is related to the pathogenesis of chronic renal failure anemia, which is considered a chronic inflammatory state as well as HCV infection. IL-6 stimulates the release of hepcidin from the liver, suppresses intestinal iron uptake, and releases iron from internal stores. METHOD To detect the association between IL-6 gene polymorphism and anemia markers, 80 hemodialysis (HD) patients [40 negative HCV HD patients and 40 positive HCV HD patients] were studied by routine chemistry and complete blood count, in addition to the assessment of serum hepcidin, iron parameters [serum iron and serum ferritin], and hepatitis C markers. IL-6 polymorphism -174G/C was determined by MS-PCR, while IL-6 polymorphisms -597G/A and -572 G/C were detected by PCR-SSP. RESULTS Hepcidin was non-significantly elevated in HCV-positive compared with HCV-negative hemodialysis patients. A statistically significant difference was detected between the negative and positive HCV HD patients in frequencies of IL-6 -174 G/C and -597 G/A (P≤ 0.01 and P≤ 0.001, respectively). On the other hand, a non-significant difference was reported between negative and positive HCV HD patients in the frequencies of IL-6 -572 G/C. CONCLUSIONS Our study indicated that IL-6 -174 G/C and -597 G/A polymorphisms may play a role in HCV susceptibility in HD patients. Additional prospective studies on a larger population are needed to confirm our findings.

Abstract
Background Direct-acting antivirals (DAAs) made a drastic change in the management of HCV infection. Sofosbuvir is one of the highly potent DAAs, eliminated mainly through the kidney. But concerns about renal safety during treatment may limit its use. Neutrophil gelatinase-associated lipocalin (NGAL) has been proven as a predictor of renal tubular injury. Hence, the aim of this work was to assess serum neutrophil gelatinase-associated lipocalin (NGAL) in HCV-positive patients before and after treatment with the sofosbuvir-based antiviral regimen. Methods This prospective study included 87 Egyptian patients with chronic HCV infection treated with sofosbuvir plus daclatasvir with or without ribavirin for 12 weeks. Serum NGAL was measured before and at the end of treatment (EOT). Analysis of NGAL and estimated glomerular filtration rate (eGFR) evolution was done. Results Our results showed a statistically significant decrease in serum NGAL (P=0.02) with a nonsignificant reduction in eGFR (P=0.02) with a nonsignificant reduction in eGFR (P=0.02) with a nonsignificant reduction in eGFR (P=0.02) with a nonsignificant reduction in eGFR (P=0.02) with a nonsignificant reduction in eGFR (. Conclusions Sofosbuvir appears to have no nephrotoxic effects and is safe to treat patients with chronic HCV infection.

Pak J Med Sci 2020; 36:286-289. [PMID: 32063976 PMCID: PMC6994872 DOI: 10.12669/pjms.36.2.1343] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Revised: 07/22/2019] [Accepted: 11/16/2019] [Indexed: 11/15/2022] Open
Abstract
OBJECTIVES To determine the frequency of anti-HCV in patients on maintenance haemodialysis (HD) and its association with history of blood transfusion and with the practice of HD from more than one center. METHODS All the patients on maintenance HD at Bahria International hospital (BIH) Rawalpindi from March 2019 to May 2019 were included. Demographic details, history of blood transfusions and history of HD from any other center in addition to BIH, were recorded. Anti-HCV was done by chemiluminescent assay. Chi-square was used to compare the categorical variables. Odds ratio (OR) and relative risk (RR) for the groups exposed to risk were calculated. RESULTS Of 96 patients, 40 (41.6%) were anti-HCV positive. Sixty-two (64.6%) had transfusion history. Thirty-one (50%) of these 62 were anti-HCV positive as compared to 9 (26.5%) of 34 with no history of transfusion (p=0.025); OR=2.78 (p=0.0278), RR=1.89 (p=0.0420). Among 66(68.7%) of 96 who had HD from other centres in addition to ours, 33(50%) were anti-HCV positive as compared to 7(23.3%) of 23 who had HD from BIH only (p=0.014); OR=3.29 (p=0.0167), RR=2.14 (p=0.0309). CONCLUSION There was a high prevalence (41.6%) of anti-HCV in our HD patients and anti-HCV positivity had significant association with history of blood transfusion as well as with history of HD from multiple centres.

Abstract
BACKGROUND Limited data exist on the pharmacokinetic profile of novel direct-acting antivirals in kidney transplant recipients. Daclatasvir is primarily eliminated through the biliary route and sofosbuvir through the renal route; here, we report the pharmacokinetic profile of combined treatment with these compounds in a prospective study of hepatitis C virus (HCV)-positive kidney transplant recipients (EudraCT: 2014-004551-32). METHODS In this study, plasma samples of 16 HCV-positive kidney transplant recipients receiving daclatasvir and sofosbuvir were collected at 4 time points at days 1, 7, 14, 21, 56, and 84 after start of treatment. Inclusion criteria were stable graft function and an estimated glomerular filtration rate (eGFR) >30 mL/min/1.73 m. Daclatasvir, sofosbuvir, and GS-331007 (inactive metabolite of sofosbuvir) plasma concentrations were determined using ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry. RESULTS All patients showed a rapid virological response with HCV RNA below the detection limit 21 days after the start of therapy (medium time to viral clearance). No difference of the areas under the concentration-time curve (AUC) of daclatasvir, sofosbuvir, and GS-331007 was observed between patients with an eGFR below or ≥60 mL/min. For GS-331007, no relevant changes of trough levels were observed over time. Mean GS-331007 trough levels were 339.5 ± 174.9 ng/mL in patients with an eGFR ≥60 mL/min and 404.3 ± 226 ng/mL in patients with an eGFR <60 mL/min at day 7 (P = 0.52). At day 84, GS-331007 trough levels were 357.8 ± 200.8 and 404.2 ± 70.2 ng/mL in patients with an eGFR ≥60 mL/min and in patients with an eGFR <60 mL/min, respectively (P = 0.51). The accumulation ratios of renally eliminated GS-331007 for AUC and Cmax did not significantly differ between the 2 eGFR groups at day 7. CONCLUSIONS An impaired eGFR (30-60 mL/min) does not lead to a dose accumulation of daclatasvir, sofosbuvir, and GS-331007. This study provides the rationale for future studies investigating the pharmacokinetic profile of sofosbuvir-based HCV treatment in kidney transplant recipients with an eGFR <30 mL/min.

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
Infectious complications have been considered as a major cause of morbidity and mortality after kidney transplantation, especially in the Asian population. Therefore, prevention, early detection, and prompt treatment of such infections are crucial in kidney transplant recipients. Among all infectious complications, viruses are considered to be the most common agents because of their abundance, infectivity, and latency ability. Herpes simplex virus, varicella zoster virus, Epstein-Barr virus, cytomegalovirus, hepatitis B virus, BK polyomavirus, and adenovirus are well-known etiologic agents of viral infections in kidney transplant patients worldwide because of their wide range of distribution. As DNA viruses, they are able to reactivate after affected patients receive immunosuppressive agents. These DNA viruses can cause systemic diseases or allograft dysfunction, especially in the first six months after transplantation. Pretransplant evaluation and immunization as well as appropriate prophylaxis and preemptive approaches after transplant have been established in the guidelines and are used effectively to reduce the incidence of these viral infections. This review will describe the etiology, diagnosis, prevention, and treatment of viral infections that commonly affect kidney transplant recipients.

Abstract
The prevalence of hepatitis C virus infection is increased in patients with end stage kidney disease compared to the general population and is an adverse outcome determinant. Direct-acting antiviral therapy for hepatitis C virus is changing the management paradigm of infected kidney transplant candidates and recipients, with potential to reduce patient morbidity and mortality. This review describes the hepatic and nonhepatic manifestations of hepatitis C virus in kidney transplant patients as well as management and treatment strategies to optimize transplant outcomes, highlighting the importance of direct-acting antivirals in this population.

Abstract
Background Direct-acting antiviral agents (DAAs) permit the use of interferon (IFN)-free regimens to treat hepatitis C (HCV) in patients with chronic kidney disease (CKD) on hemo-dialysis (HD) or renal transplant (RTx) recipients, with excellent response rates and safety. However, the occurrence of basal or therapy-induced resistance-associated substitutions (RASs) to DAAs can result in treatment failure. The aim of this study was to estimate the prevalence of RASs to NS3A, NS5A and NS5B inhibitors, and particularly the Q80K polymorphism, in CKD patients on HD and RTx recipients infected with HCV. Patients and methods HD and RTx patients infected with HCV-genotype 1 (GT1) were subjected to sequencing of the NS3, NS5A and NS5B regions. Results Direct sequencing of NS3 protease, NS5A and NS5B was performed in 76 patients (HD, n=37; RTx, n=39). The overall prevalence of RASs was 38.2%, but only 5.3% of the patients had mutations in more than one region. Substitutions were detected in NS3A (17.8%), NS5A (21.9%) and NS5B (8.4%). Q80K was detected in 1.5 % of the patients. Highly inhibitory RASs were uncommon (L31M, 2.6%; L159F+C316N, 2.6%). RASs were more prevalent in HCV-GT1a (42.9%) than in HCV-GT1b (32.4%), P=0.35. RASs were detected in 52.4% of treatment-naive patients and 27.8% of peg-IFN/ribavirin-experienced patients (P=0.12). The presence of RASs was associated with time of RTx (P=0.01). Conclusion The Q80K polymorphism was uncommon in our sample of HD and RTx patients. Despite the high prevalence of naturally occurring RASs, most of the substitutions detected were associated with a low level of resistance to DAAs.

Abstract
PURPOSE OF REVIEW To highlight the changing landscape of hepatitis C virus (HCV) infection in the context of organ transplantation. This focuses on areas of controversy and future potential in the era of highly effective direct-acting antiviral (DAA) agents. RECENT FINDINGS Since the advent of safe and highly effective DAA therapy, HCV infection is now curable in virtually all cases, including organ transplant recipients. Excellent drug tolerability and safety combined with high cure rates across all organ groups means that HCV is no longer a barrier to transplantation or its outcomes. Mounting data demonstrate the safety of using organs from HCV-infected donors with subsequent treatment of HCV in the recipient and a potential to expand the donor pool. Historical data demonstrating inferior survival in transplant recipients with HCV is of limited relevance in the DAA era. Virtually all transplant recipients with HCV infection can be cured, while early data also suggest excellent outcomes in recipients of organs from HCV viremic donors. The optimal timing of HCV therapy in relation to transplantation and the optimal use of organs from HCV viremic donors remain areas of controversy and ongoing research efforts.

Abstract
INTRODUCTION AND AIM Occult hepatitis C infection (OHCI) is the presence of HCV-RNA in the liver or peripheral blood mononuclear cells (PBMC) accompanying with negative serologic results. The aim of this study was to evaluate the prevalence of OHCI among Iranian chronic hemodialysis (HD) patients. MATERIAL AND METHODS In this cross sectional study 200 chronic HD patients with negative HCV antibody enrolled the study. Blood sample of patients were obtained, followed by Polymerase Chain reaction (PCR) testing for detection of HCV RNA. Patients with positive serum HCV RNA were considered as manifest hepatitis C infection (MHCI). However, patients with negative serum HCV RNA underwent further tests on PBMCs for detection of OHCI. RESULTS Serum HCV RNA was positive in 2 (1%) patients whom considered as MHCI, and 6 (3.03%) patients had positive PBMC HCV RNA. CONCLUSION In conclusion, chronic HD patients have been considered as a high risk group for hepatitis C infection. The results of this study suggest that these patients are also at risk for OHCI. Furthermore, evaluating PBMCs to detect HCV RNA would be a sensitive diagnostic method to find OHCI patients.

Abstract
BACKGROUND AND AIM The epidemiology and clinical profile of hepatitis C virus (HCV) varies worldwide, and data from developing countries are sparse. The aim of the present study was to assess the clinical profile of HCV infection in a developing country in South-East Asia (India). METHODS This observational study assessed patient demographics, viral characteristics, risk factors for virus acquisition, and disease characteristics in HCV patients diagnosed between January 2004 and December 2015. RESULTS Of 8035 patients who were diagnosed with HCV infection, a majority were men (68.3%), middle aged (52.2%), and from low (34%) to middle (46%) socioeconomic status and rural population (69.8%). Eighty-two percent had identifiable risk factors, the most common being history of dental treatment (52%) and therapeutic injections with reusable syringes/needles (45%). Household contacts of index patients had high prevalence of HCV (15.3%). Common genotypes were genotype 3 (70.4%) and genotype 1 (19.3%). Although a majority of patients were either asymptomatic (54.8%) or had non-specific symptoms (6.7%) at presentation, a significant proportion (9.3%) had advanced liver disease. Presentation with cirrhosis (38.8%) was associated with male gender, higher age at time of virus detection, rural residence, alcohol or opium intake, and coinfections with hepatitis B virus or human immunodeficiency virus. CONCLUSIONS Hepatitis C virus infection in northern India is seen more commonly in men, the middle aged and people from rural background and low to middle socioeconomic status. The common possible risk factors are dental treatment and exposure to reused syringes and needles. Although the most common presentation is incidental detection, a large number of patients present with advanced liver disease.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is still common among dialysis patients, but the natural history of HCV in this group is not completely understood. The KDIGO HCV guidelines of 2009 recommend that chronic haemodialysis patients be screened for HCV antibody upon admission to the dialysis clinic and every 6 months thereafter if susceptible to HCV infection. However, previous studies have shown the presence of HCV viraemia in anti-HCV-negative haemodialysis patients as up to 22%. OBJECTIVES To evaluate the presence of HCV viraemia, using HCV RNA detection, among anti-HCV-negative haemodialysis patients from a tertiary dialysis unit in Athens. METHODS We enrolled 41 anti-HCV-negative haemodialysis patients diagnosed with third-generation enzyme immunoassay. HCV viraemia was evaluated using a sensitive (cut-off: 12 IU/mL) reverse transcriptase polymerase chain reaction (COBAS AmpliPrep/TaqMan system) for HCV RNA. RESULTS None of the 41 anti-HCV-negative haemodialysis patients were shown to be viraemic. CONCLUSIONS Routine HCV RNA testing appears not to be necessary in anti-HCV-negative haemodialysis patients.

Abstract
Hepatitis C virus (HCV) infection, a major cause of end-stage liver disease, is a common comorbidity in patients on dialysis and causes increased morbidity and mortality. Historically HCV has been extremely difficult to cure with interferon and ribavirin-based therapies, which are also associated with significant side effects, and few dialysis patients ever received HCV treatment. However, in the last 4 years, interferon-free direct-acting antiviral therapies have been approved, and several combinations have been studied in dialysis patients. A recently approved, pan-genotypic, direct-acting antiviral regimen, glecaprevir and pibrentasvir, may simplify prescribing. The simplicity of these new therapies, with few side effects, makes it possible for nephrologists to treat HCV infection in their patients on dialysis. We review the workflow and motivation behind nephrology-led management of HCV infection. We highlight the importance of identifying which patients need referral to a hepatologist or HCV specialist prior to treatment and which can be managed by their nephrologist. Nephrologist involvement would lead to improved access to treatment and ensure that appropriate patients are referred for HCV treatment. In this paper, we review the background of HCV infection, its effect on dialysis patients, and impact on kidney transplantation. In addition, we outline the therapy options for each genotype of HCV, and we discuss the benefits and barriers to nephrology-led HCV treatment.

Potential Hepatoprotective Role of Galectin-3 during HCV Infection in End-Stage Renal Disease Patients. DISEASE MARKERS 2017; 2017:6275987.

Abstract
Hepatitis C virus infection (HCV), one of the greatest causes of liver disease, is a frequent complication in patients with end-stage renal disease (ESRD) on dialysis. ESRD is defined as decreased glomerular filtration and also accompanied by impaired function of the immune system. Galectin-3 is a β-galactoside-binding lectin, involved in various biological processes including pathogenesis of chronic renal disease. The aim of our study was to estimate disease severity in ESRD HCV+ patients and analyze the serum concentrations of IL-1β, IL-4, IL-23, and IL-6; anti-HCV antibodies; and galectin-3. Also, we attempted to determine potential correlation between galectin-3 level and parameters of disease severity ALT and AST. Our results showed decreased levels of ALT and AST (p = 0.00), demonstrating less liver destruction in ESRD HCV+ patients in comparison to HCV+ patients. Increased levels of IL-6 (p = 0.03) implicate a hepatoprotective role of IL-6 in these patients. Also, level of galectin-3 (p = 0.00) in the serum of ESRD HCV+ patients was higher than that of HCV+ patients. This alteration was accompanied with negative correlation between galectin-3 and AST and ALT, respectively (p = 0.029; p = 0.033). The presence of increased systemic levels of IL-6 and Gal-3 in ESRD HCV+ patients may be an attempt to counteract or limit ongoing proinflammatory processes and to downregulate chronic inflammation, suggesting the new aspects of HCV infection in ESRD patients.

Abstract
There is no consensus regarding which therapeutic option is better and/or safer for treating hemodialysis (HD) patients with hepatocellular carcinoma (HCC). The present study compared surgical resection (Hx) and radiofrequency ablation (RFA) with regard to therapeutic efficacy in HD patients with HCC. Of 108 HD patients with naïve HCC treated at 15 institutions between 1988 and 2014 enrolled in the present study, 58 fulfilled the up-to-7 criteria [7 as the sum of the size of the largest tumor (cm) and the number of tumors] and were treated with Hx (n=23) or RFA (n=35); their clinical features, complications and prognosis were assessed. The frequency of hepatitis C virus was higher in the RFA group compared with that in the Hx group (P=0.002), whereas there were no differences between the groups with regard to the average time from the first HD (P=0.953), tumor-nodes-metastasis (TNM) stage (Union for International Cancer Control 7th edition) (P=0.588), TNM stage (Liver Cancer Study Group of Japan 5th edition) (P=0.095), Child-Pugh classification (P=0.094), and Japan Integrated Scoring system (P=0.489). There were no significant differences in overall survival (OS) and disease-free survival (DFS) rates between the Hx and RFA groups [1-, 3- and 5-year OS rates: 81.7, 55.6 and 43.3% vs. 89.9, 67.1 and 56.3%, respectively (P=0.454); 1-, 3- and 5-year DFS rates: 71.1, 30.5 and 18.3% vs. 63.8, 31.6 and 21.1%, respectively (P=0.911)] Complications were observed in 4 patients (11.4%) in the RFA group (2 with subcapsular hemorrhage, 1 with intraperitoneal bleeding and 1 with tardive intrahepatic hematoma) and in 4 patients (17.4%) in the Hx group (2 with postoperative infection, 1 with liver failure and 1 with pleural effusion) (P=0.700). In conclusion, Hx and RFA have a similar therapeutic efficacy in HD patients with naïve HCC who fulfilled the up-to-7 criteria.

Abstract
Introduction There are reports suggesting that hepatitis C virus (HCV) may stimulate the autoimmune process. Studies have been undertaken to evaluate the occurrence and type of autoantibodies in HCV-infected patients with and without immunosuppression. Results were analyzed according to HCV genotype, intensity of inflammation and liver fibrosis stage. Material and methods The study included 105 patients chronically infected with HCV, including 25 with immunological suppression administered for kidney disease or kidney transplantation. Blood samples were tested by immunoblotting for the presence of AMA-M2, SLA/LP, LKM-1, LC1, anti-F-actin, anti-desmin, anti-myosin, anti-gp210 and anti-sp100 autoantibodies, and ANA. All the patients were scored for autoimmune hepatitis. Results Autoantibodies were detected in 32.5% of patients without immunosuppression and in 16% with immunosuppression. Single types of autoantibodies were identified in 26% of patients. The most frequent ones were ANA (19%) and AMA-M2 (5.7%). The presence of antibodies in patients with genotype 1 was significantly higher in comparison to their occurrence in genotype 3. Autoimmune hepatitis was not diagnosed in any of the patients. Immunoglobulin G level was significantly higher in patients with detectable autoantibodies, compared to patients without antibodies (1.89 vs. 1.28 g/dl, p < 0.001). No correlation between fibrosis stage or intensity of inflammatory state and the frequency of antibodies was found. Conclusions The antibodies are significantly more frequent in patients without immunosuppression and in patients infected with genotype 1 than genotype 3. The presence of these autoantibodies is not associated with the development of autoimmune hepatitis. Higher level of immunoglobulin G in the serum correlates with the presence of autoantibodies.

Abstract
Treatment of hepatitis C virus (HCV) in end-stage renal disease (ESRD) patients is an important issue before kidney transplantation (KT). The aim of the study is to assess the efficacy and tolerability of HCV treatment with pegylated interferon (PEG IFN)-α 2b in children with ESRD. The study included 17 children, aged 3-18 years with ESRD on hemodialysis (HD), with chronic HCV. They received 40 μg/m2 of PEG IFN-α 2b once-weekly subcutaneous injections for 48 weeks. Early virological response (EVR) was achieved in 76.5%. At week 24, 8 patients had negative HCV RNA. Six patients received KT during therapy. Treatment was discontinued in 2 patients: one for anemia and another for retinopathy. Two patients completed 48 weeks of therapy and both achieved end-of-treatment response and sustained virological response (SVR). Constitutional symptoms were the most frequently reported side effects. Neutropenia occurred in 10 patients (58.8%), drop in hemoglobin in 10, and thrombocytopenia in 9. HCV-infected children with ESRD on HD have high EVR (76.5%) on IFN monotherapy. SVR could not be assessed due to the high dropout rate related mainly to early transplantation. Constitutional symptoms and hematological side effects were the most frequently reported side effects.

Abstract
BACKGROUND The hepatitis C virus (HCV) infection affects about 2% of the world's population and can cause chronic liver infection and persistent long-term sequelae such as cirrhosis and liver cancer.The prevalence of HCV infection among people on haemodialysis is often higher than the general population. The virus is easily transmitted parenterally, and blood transfusions have previously played a significant role in transmission; however, erythropoietin therapy has reduced the need for transfusions, and coupled with improved screening of donated blood, has significantly decreased transmission by transfusion. Although control of hospital-acquired infection has improved with the advent of biosafety measures, stopping HCV transmission in haemodialysis units remains challenging.Isolating people infected with HCV involves physical separation from others to limit direct or indirect transmission and includes a number of strategies during dialysis. The evidence for isolating people infected with HCV during haemodialysis is sparse with some inconsistencies. OBJECTIVES To evaluate the benefits and harms of isolation of HCV-infected patients during haemodialysis on the transmission of HCV to other patients. SEARCH METHODS We searched the Cochrane Kidney and Transplant Specialised Register to 26 November 2015 through contact with the Information Specialist using search terms relevant to this review. We also searched the Latin American and Caribbean Health Sciences Literature Database (LILACS) (1982 to 2015), Web of Science Conference Proceedings Citation Index-Science (CPCI-S, 1990 to 2015), ProQuest Dissertations & Theses Database (1990 to 2015), and Open Grey (1990 to 2015). SELECTION CRITERIA We included randomised controlled trials (RCTs), quasi-RCTs and cluster RCTs evaluating the clinical benefits and harms of isolating HCV-infected patients during haemodialysis on the transmission of HCV to other patients. We considered incidence of dialysis-acquired HCV infection, all-cause mortality, and adverse effects associated with isolation as the primary outcomes. DATA COLLECTION AND ANALYSIS Summary estimates of effect were obtained using a random-effects model, and results were expressed as risk ratios (RR) and their 95% confidence intervals (CI) for dichotomous outcomes, and mean difference (MD) or standardised mean difference (SMD) and 95% CI for continuous outcomes. MAIN RESULTS Only one study, which included 12 centres was identified: four centres used dedicated haemodialysis machines for HCV-infected patients and eight centres used non-dedicated machines. The total number of patients enrolled was 593. One centre was excluded after randomisation. Random sequence generation was not described and allocation concealment was not performed. Participants and personnel were not blinded and blinding of outcome assessors was not reported. Only 74.5% of the patients were followed for 9 months; and 47.3% were followed for an additional 9 months. The authors only reported one outcome, measuring the difference in the incidence of HCV in both groups. The authors did not consider the exposure time, to determine the adjusted rate of seroconversion risk/patient-year. The study reported that the incidence of HCV infection during the first follow-up period (9 months) was 1.6% in the dedicated group, and 4.7% in the non-dedicated one (446 patients analysed out of 593 randomised; RR 0.34, 95% CI 0.11 to 1.07). During the second follow-up period (18 months) the incidence was 1.3% in the dedicated group and 5.8% in the control (281 patients analysed out of 593 randomised; RR 0.22, 95% CI 0.05 to 1.02). Therefore, we found no differences in terms of the number of participants developing HCV infection when comparing the dedicated group with the usual care. Moreover, the evidence was of very low quality, which means that we have very little confidence in the effect estimate. AUTHORS' CONCLUSIONS The benefits and harms of isolation of HCV-infected patients during haemodialysis on the transmission of HCV to other patients are uncertain. Evidence from one short-duration cluster-randomised study with a high risk of bias did not find differences in terms of the number of participants developing HCV infection when comparing the use of dedicated haemodialysis machines for HCV infected patients with the use of non-dedicated machines.

Abstract
AIM: To evaluate neutrophil gelatinase associated lipocalin (NGAL) in patients infected by hepatitis C virus (HCV) before and during treatment with directly acting antivirals (DAAs).
METHODS: NGAL was measured in a group of patients with chronic HCV infection ranked, at baseline, by age, gender, anti-hypertensive therapy, HCV viral load, liver fibrosis stage and, either at baseline or after 1 year, estimated glomerular filtration rate (eGFR). Then, NGAL and eGFR evolutions were monitored in a subgroup of patients who started antiviral therapy with DAAs. Differences of median NGAL levels were evaluated through Wilcoxon-Mann-Whitney test for non-parametric data. Differences in dichotomous variables were evaluated through χ2 test. At baseline, a univariate regression analysis was conducted to verify if NGAL values correlated with other quantitative variables [age, fibrosis four (FIB-4), AST to platelet ratio index (APRI), and eGFR].
RESULTS: Overall, 48 patients were enrolled, 8 of them starting HCV treatment. At baseline, statistically significant differences were found in median NGAL values only between patients with eGFR < 60 mL/min vs patients with eGFR ≥ 90 mL/min. Differences in NGAL were not significant among patients ranked by HCV viral load, FIB-4 score and APRI, when patients with NGAL > 118.11 ng/dL were compared with those of NGAL ≤ 118.11 ng/dL, not statistically significant differences were present for age, gender, chronic kidney disease classification and liver fibrosis (P > 0.05). Linear correlation was found between NGAL and both age (P = 0.0475) and eGFR (P = 0.0282) values. Not statistically significant predictions of NGAL at baseline were demonstrated for eGFR evolution 1 year later. Interestingly, in the 8 patients treated with DAAs, median NGAL significantly increased at week 12 compared to baseline (P = 0.0239).
CONCLUSION: Our results suggest that NGAL should be further evaluated as an adjunct marker of kidney function in these patients.

Abstract
Hepatitis C virus (HCV) infection is estimated to affect 130-150 million people globally which corresponds to 2%-3% of the total world population. It remains the leading indication for liver transplant worldwide and has been demonstrated to negatively impact both patient and graft survival following non-hepatic organ transplantation. In the era of interferon-based therapy, although treatment and cure of HCV prior to non-hepatic transplant improved survival, tolerability and low cure rates substantially limited therapy. Interferon (IFN)-based therapy following non-hepatic solid organ transplant, due to the risk of allograft rejection, is generally contraindicated. Rapid advances in IFN-free therapy with direct acting antivirals (DAAs) in the last few years have completely changed the paradigm of hepatitis C therapy. Compared to IFN-based regimens, DAAs have less frequent and less severe adverse effects, shorter durations of therapy, and higher cure rates that are minimally impacted by historically negative predictors of response such as cirrhosis, ethnicity, and post-transplant state. Recent studies have shown that liver transplant (LT) recipients can be safely and effectively treated with DAA combination therapies; although data are limited, many of the principles of therapy in LT may be extrapolated to non-hepatic solid organ transplant recipients. Here we review the data on DAA combination therapies in transplantation, discuss the advantages and disadvantages of pre- vs post-transplant HCV therapy and future directions.
