The world prevalence, associated risk factors and mortality of hepatitis C virus infection in hemodialysis patients: a meta-analysis. J Nephrol 2022; 35:2269-2282. [PMID: 36383211 PMCID: PMC9666992 DOI: 10.1007/s40620-022-01483-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2022] [Accepted: 10/01/2022] [Indexed: 11/17/2022]
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
Prevalence rates of HCV infection are decreasing in hemodialysis units of most developed countries; however, nosocomial transmission of HCV continues to occur in the hemodialysis setting, not only in the emerging world. According to the Dialysis Outcomes and Practice Patterns Study (DOPPS, 2012–2015), the prevalence of HCV among patients on regular hemodialysis was 9.9%; in incident patients, the frequency of HCV was approximately 5%. Outbreaks of HCV have been investigated by epidemiologic and phylogenetic data obtained by sequencing of the HCV genome; no single factor was retrieved as being associated with nosocomial transmission of HCV within hemodialysis units. Transmission of HCV within HD units can be prevented successfully by full compliance with infection control practices; also, antiviral treatment and serologic screening for anti-HCV can be useful in achieving this aim. Infection control practices in hemodialysis units include barrier precautions to prevent exposure to blood-borne pathogens and other procedures specific to the hemodialysis environment. Isolating HCV-infected hemodialysis patients or using dedicated dialysis machines for HCV-infected patients are not currently recommended; reuse of dialyzers of HCV-infected patients should be made, according to recent guidelines. Randomized controlled trials regarding the impact of isolation on the risk of transmission of HCV to hemodialysis patients have not been published to date. At least two studies showed complete elimination of de novo HCV within HD units by implementation of strict infection control practices without isolation practices. De novo HCV within hemodialysis units has been independently associated with facility HCV prevalence, dialysis vintage, and low staff-to-patient ratio. Antiviral treatment of HCV-infected patients on hemodialysis should not replace the implementation of barrier precautions and other routine hemodialysis unit procedures.

Abstract
Hepatitis C virus (HCV) infection is a global health problem with significant health and economic burden, which can lead to chronic kidney disease (CKD) and affect multiple organ systems. In addition, prevalence of hepatitis C remains higher in patients with CKD, including those on chronic hemodialysis and in individuals with a kidney transplant than in the general population. There has been a dramatic shift in the management of hepatitis C since Kidney Disease: Improving Global Outcome (KDIGO) published its 2008 guideline for the prevention, diagnosis and management of hepatitis C in CKD. As a result, KDIGO published in 2018 an update to this guideline. In this narrative review, we present a synopsis of the guideline, including recommendations for screening and detection of HCV in CKD, treatment of HCV in patients with CKD, treatment of HCV before and after kidney transplantation, prevention of HCV transmission in hemodialysis units, and treatment of kidney disease related to HCV infection. We focus on the clinical aspects of using direct acting antivirals (DAAs) in patients with advanced CKD (G4 and G5), those on dialysis and kidney transplant recipients. We emphasize the importance of carefully managing drug-drug interactions between DAAs and immunosuppressive agents. We discuss timing of HCV treatment before vs. after kidney transplantation. Finally, we highlight areas of uncertainty where further research is needed before any definitive recommendations can be made.

Abstract
According to data from the last census of the Brazilian Society of Nephrology (SBN), the prevalence of hepatitis C virus (HCV) in Brazilian hemodialysis units (HU) is 3.3%, about three times higher than what is reported for the Brazilian general population. Often, professionals working in HU are faced with clinical situations that require rapid HCV diagnosis in order to avoid horizontal transmission within the units. On the other hand, thanks to the development of new antiviral drugs, the cure of patients with HCV, both in the general population and in patients with chronic kidney disease and the disease eradication, appear to be very feasible objectives to be achieved in the near future . In this scenario, SBN and the Brazilian Society of Hepatology present in this review article a proposal to approach HCV within HUs.

Abstract
Hepatitis B and hepatitis C (HCV) prevalence are higher in people on hemodialysis (HD) than the general population. Through implementation of prevention interventions including vaccines, serologic screening, and post-exposure management, transmissions linked to HD have decreased dramatically. In this manuscript, we review epidemiology of viral hepatitis, summarize current screening and vaccine recommendations, and appraise the available data about efforts to decrease incidence within HD facilities, including isolation of people with viral hepatitis within HD units. Also included is a discussion of the highly effective all-oral HCV treatment options and treatment for HCV in people awaiting kidney transplant.

Abstract
Increase in the number of patients with chronic kidney disease (CKD) calls for improved management of these patients. In stage 5 CKD, when the initiation of renal replacement therapy (RRT) becomes necessary, there is an increase in the infection risk of the patients and immunological tests for hepatitis C virus (HCV) detection turn positive at an alarmingly higher rate compared to general population. With the introduction into clinical practice of diagnostic tests, the increased prevalence of HCV among CKD patients has been known since the 1990s. Also, the negative impacts of HCV infection on CKD evolution as well as the unfavorable evolution of grafts received by HCV infected patients are known. Chronic hemodialysis patients are a category of patients whose risk of HCV infection is substantial. Currently, in the hemodialysis centers, at the base of the transmission of HCV infection there are a multitude of factors. Infection with HCV has a different impact on patient with end-stage renal disease (ESRD). Comorbidities in this case have significant sources of mortality and morbidity. It was proven that the post transplantations problems were prevented and mortality was reduced for patients who were diagnosed with HCV and in whom the infection was treated before the kidney transplant (KT). Consequently, early detection of the infection and the application of specific treatment has a considerable impact on the outcome of the patients. Another important component of the management of HCV infection in the chronic hemodialysis patients is the prevention of the infection transmission by applying specific methods.

Abstract
Some people who are receiving dialysis treatment have virus infection such as hepatitis B, hepatitis C and/or HIV that is present in their blood. These infections can be transmitted to other patients if blood is contaminated by the blood of another with a viral infection. Haemodialysis is performed by passing blood from a patient through a dialysis machine, and multiple patients receive dialysis within a dialysis unit. Therefore, there is a risk that these viruses may be transmitted around the dialysis session. This documents sets out recommendations for minimising this risk.There are sections describing how machines and equipment should be cleaned between patients. There are also recommendations for dialysing patients with hepatitis B away from patients who do not have hepatitis B. Patients should be immunised against hepatitis B, ideally before starting dialysis if this is possible. There are guidelines on how and when to do this, for checking whether immunisation is effective, and for administering booster doses of vaccine. Finally there is a section on the measures that should be taken if a patient receiving dialysis is identified as having a new infection of hepatitis B, hepatitis C or HIV.

Abstract
In this review article, we cover 4 topics very relevant to those involved in the care of hemodialysis (HD) patients and in the management of a HD unit. We start with an overview of the progress made over the last 25 years to reduce hepatitis C virus (HCV) transmission in HD. Next, we discuss the potential strategies to prevent the residual ongoing transmission of HCV to HD patients. Third, we discuss the actions to be taken if a seroconversion for HCV is nevertheless detected in a HD patient. Finally, we briefly discuss how best to protect HD staff members from occupationally acquired HCV infection.

Abstract
Hepatitis B virus (HBV) and hepatitis C virus (HCV) cause 1.3 million deaths annually. To prevent more than 7 million deaths by 2030, the World Health Organization set goals to eliminate HBV and HCV, defined as a 90% reduction in new infections and a 65% reduction in deaths, and prevent more than 7 million related deaths by 2030. Elimination of HBV and HCV is feasible because of characteristics of the viruses, reliable diagnostic tools, and available cost-effective or cost-saving interventions. Broad implementation of infant immunization against HBV, blood safety, and infection-control programs have greatly reduced the burden of HBV and HCV infections. To achieve elimination, priorities include implementation of HBV vaccine-based strategies to prevent perinatal transmission, safe injection practices and HCV treatment for persons who inject drugs, and testing and treatment for HBV- and HCV-infected persons. With sufficient capacity, HBV and HCV elimination programs can meet their goals.

Abstract
Hepatitis C virus (HCV) infection is now considered a systemic disease due to the occurrence of extra-hepatic manifestations. Among these, the renal involvement is frequent. HCV infection, in fact, is strongly associated with proteinuria and chronic kidney disease (CKD) and negatively affects the prognosis of renal patients. In the last few years, availability of more specific and effective drugs against HCV has dramatically changed the clinical course of this disease. These drugs may provide further advantages in the CKD population as a whole by reducing progression of renal disease, mortality rate and by increasing the survival of graft in renal transplant recipients. The strict pathogenetic and prognostic link between HCV infection and CKD requires an ongoing relationship among the healthcare professionals involved in the treatment of both HCV infection and CKD. Therefore, Scientific Societies involved in the care of this high-risk population in Italy have organized a joint expert panel. The aim of the panel is to produce a position statement that can be used in daily clinical practice for the management of HCV infected patients across the whole spectrum of renal disease, from the conservative phase to renal replacement treatments (dialysis and transplantation). Sharing specific evidence-based expertise of different professional healthcare is the first step to obtain a common ground of knowledge on which to instate a model for multidisciplinary management of this high-risk population. Statements cover seven areas including epidemiology of CKD, HCV-induced glomerular damage, HCV-related renal risk, staging of liver disease in patients with CKD, prevention of transmission of HCV in hemodialysis units, treatment of HCV infection and management of HCV in kidney transplantation.

Abstract
Hepatitis C virus (HCV) infection is not only an important cause of chronic liver disease, but extrahepatic manifestations are common and include chronic kidney disease (CKD). HCV is classically associated with cryoglobulinemic glomerulonephritis in the context of mixed cryoglobulinemia syndrome, but other glomerular diseases also occur and may be significantly under-recognized. HCV may cause glomerular disease by immune complex deposition; however, other potential mechanisms by which HCV promotes CKD include a direct cytopathic effect of the virus on renal tissue, and by its association with accelerated atherosclerosis, insulin resistance, and chronic inflammation. Epidemiologic studies show HCV infection confers an increased risk of incident CKD and accelerates progression of CKD to end-stage renal disease (ESRD) in the general population, as well as subpopulations including diabetic patients, those coinfected with human immunodeficiency virus (HIV), and kidney transplant recipients. Patients with CKD and HCV infection experience inferior clinical outcomes, including poorer quality of life and an increased risk of mortality. Treatment with interferon-based regimens is associated with decreased risk of incident CKD and ESRD, though prior studies are limited by the small number of patients with HCV and CKD who underwent treatment. With the advent of new, well-tolerated direct-acting antiviral combinations that are not cleared by the kidneys, it is possible to treat all genotypes of HCV infection in patients with CKD and ESRD. More data on the effect of direct-acting antivirals on CKD incidence and progression are necessary. However, there is every expectation that with improved access to HCV treatment, the burden of CKD in patients with HCV could significantly decline.

Abstract
Hepatitis C virus (HCV) infection is now considered a systemic disease due to the occurrence of extra-hepatic manifestations. Among these, the renal involvement is frequent. HCV infection, in fact, is strongly associated with proteinuria and chronic kidney disease (CKD) and negatively affects the prognosis of renal patients. In the last few years, availability of more specific and effective drugs against HCV has dramatically changed the clinical course of this disease. These drugs may provide further advantages in the CKD population as a whole by reducing progression of renal disease, mortality rate and by increasing the survival of graft in renal transplant recipients. The strict pathogenetic and prognostic link between HCV infection and CKD requires an ongoing relationship among the healthcare professionals involved in the treatment of both HCV infection and CKD. Therefore, Scientific Societies involved in the care of this high-risk population in Italy have organized a joint expert panel. The aim of the panel is to produce a position statement that can be used in daily clinical practice for the management of HCV infected patients across the whole spectrum of renal disease, from the conservative phase to renal replacement treatments (dialysis and transplantation). Sharing specific evidence-based expertise of different professional healthcare is the first step to obtain a common ground of knowledge on which to instate a model for multidisciplinary management of this high-risk population. Statements cover seven areas including epidemiology of CKD, HCV-induced glomerular damage, HCV-related renal risk, staging of liver disease in patients with CKD, prevention of transmission of HCV in hemodialysis units, treatment of HCV infection and management of HCV in kidney transplantation.

Abstract
Hepatitis C virus (HCV) is a parenterally-transmitted hepatotropic virus that often causes chronic infection, which can progress to cirrhosis and hepatocellular carcinoma. Development of highly effective direct-acting anti-viral agents (DAAs) has led to a paradigm change in the treatment of HCV infection over the last 4-5 years. Patients with chronic kidney disease (CKD) are at a higher risk of acquiring HCV infection. In these patients, diagnosis of HCV infection, assessment of the consequent liver disease and management of HCV infection pose some specific problems. This article reviews the available recent information on HCV infection and CKD, including the association between these conditions and their effect on each other, and prevention, evaluation, and management of HCV infection in persons with CKD. This review looks at this issue particularly from the perspective of readers in Asia, especially India, since the epidemiology of HCV-CKD association and the repertoire of anti-HCV drugs available in this region differ from those elsewhere.

Abstract
BACKGROUND & AIMS The recommended combination of pangenotypic direct-acting antivirals (DAAs) for the treatment of hepatitis C virus (HCV) associates the co-formulation of 2 or 3 second-generation DAAs. In the so-called "special populations" defined as patients with chronic kidney disease (CKD), HCV/HIV co-infection, HCV/HBV co-infection and an unsuccessful previous DAA regimen, these combinations have a high antiviral potency (sustained virologic response (SVR) > 95%), fair tolerance and a reduced pill burden. METHODS We have taken into account the scientific evidence on the treatment of "special populations", in particular from the RUBY 1-2 trials, EXPEDITION 2-4 study, C-WORTHY trial, ASTRAL 5, POLARIS 1-4 studies, MAGELLAN 1 and REVENGE study. RESULTS CKD and HCV/HIV co-infection are not predictors of a non-viral response. The glecaprevir/pibentrasvir (Maviret) combination appears to be the first-line therapy for CKD patients while the sofosbuvir/vlpatasvir/voxaliprevir (Sovesi) combination is the first-line option for DAAs failures. Both are effective in patients with HIV-or HBV-HCV co-infection and should be chosen according to the potential drug-drug interaction profile. CONCLUSIONS The notion of "special populations" is no longer pertinent with pangenotypic DAAs combinations. International guidelines recommend treating all infected patients and the next challenge is not the therapeutic choice, but to improve the limitations for screening and access to care in HCV infection.

Abstract
A variety of epidemiological data provides evidence for the occurrence of nosocomial transmission of hepatitis C virus (HCV) infection to hemodialysis (HD) patients. The most important factor implicated in HCV transmission between patients treated in the same dialysis unit is cross-contamination from supplies and surfaces as a result of failure of staff to follow infection control procedures. Parts of the HCV genome are highly variable and lend themselves to fingerprinting of each isolate using nucleic acid testing (NAT) and sequencing. This approach has permitted investigation of possible transmission routes within HD units. A systematic review of molecular virology papers revealed transmission of HCV via internal fluid pathways of the dialysis machines in a minority of reports only. Dialyzer reuse was not identified as a risk factor for HCV acquisition in multicenter databases. No randomized controlled trials exist on the impact of isolation on the risk of transmission of HCV to hemodialysis patients. A Belgian prospective multicenter study showed a reduction from 1.4% to 0% in the annual incidence of seroconversion for HCV without any isolation measures, by implementation of strict infection control procedures designed to prevent transmission of blood-borne pathogens, including HCV. However, an isolation policy for HCV-infected dialysis patients should be considered in dialysis units where nosocomial transmission of HCV persists despite reinforcement and audit of hygienic precautions for hemodialysis. Routine audit precautions (general and for dialysis machines) are recommended on a regular basis within HD units.

Abstract
The study aimed to estimate the incidence of HCV seroconversion in hemodialysis patients in the Brazilian Unified National Health System (SUS). This was a prospective, non-concurrent study using patients' data identified by deterministic and probabilistic record linkage in the SUS information system. The study included 47,079 patients started on hemodialysis between January 1, 2000, and December 31, 2003, followed until seroconversion or conclusion of the study in 2004. Three percent of hemodialysis patients HCV-seroconverted (1.7 per 100 patient-years). Increased risk of HCV seroconversion was associated with age, glomerulonephritis, geographic region, HIV-positivity, and dialysis service. The observed HCV seroconversion rate was similar to that in developed countries, highlighting evidence of transmission among hemodialysis patients.

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
AbstractObjective:To identify modes of HCV transmission during an outbreak of HCV infection in a hemodialysis unit.Design:An epidemiologic study, virologie analysis, assessment of infection control practices and procedures, and technical examination of products and dialysis machines.Setting:A private hemodialysis unit treating approximately 70 patients.Patients:Detection of HCV RNA by PCR was performed among patients receiving dialysis in 2001. Case-patients were patients who had a first positive result for HCV RNA between January 2001 and January 2002 and either acute hepatitis, a seroconversion for HCV antibodies, or a previous negative result. Three control-patients were randomly selected per case-patient.Results:Of the 61 patients treated in the unit in 2001 and not infected with HCV, 22 (36.1%) became case-patients with onset from May 2001 to January 2002 for an incidence density rate of 70 per 100 patient-years. Phylogenic analysis identified four distinct HCV groups and an index case-patient for each with a similar virus among patients already known to be infected. No multidose medication vials or material was shared between patients. Connection to a dialysis machine by a nurse who had connected an HCV-infected patient “just before” or “one patient before” increased the risk of HCV infection, whereas using the same dialysis machine after a patient infected with HCV did not. Understating, lack of training, and breaches in infection control were documented. Direct observation of practices revealed frequent flooding of blood into the double filter on the arterial pressure tubing set.Conclusions:During this outbreak, HCV transmission was mainly patient to patient via healthcare workers' hands. However, transmission via dialysis machines because of possible contamination of internal components could not be excluded.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is a major blood-borne infection which imposes high economic cost on the patients. OBJECTIVES The current study aimed to evaluate the total annual cost due to chronic HCV related diseases imposed on each patient and their family in Southern Iran. PATIENTS AND METHODS Economic burden of chronic hepatitis C-related liver diseases (chronic hepatitis C, cirrhosis and hepatocellular carcinoma) were examined. The current retrospective study evaluated 200 Iranian patients for their socioeconomic status, utilization (direct and indirect costs) and treatment costs and work days lost due to illness by a structured questionnaire in 2015. Costs of hospital admissions were extracted from databases of Nemazee hospital, Shiraz, Iran. The outpatient expenditure per patient was measured through the rate of outpatient visits and average cost per visit reported by the patients; while the inpatient costs were calculated through annual rate of hospital admissions and average expenditure. Self-medication and direct non-medical costs were also reported. The human capital approach was used to measure the work loss cost. RESULTS The total annual cost per patient for chronic hepatitis C, cirrhosis and hepatocellular carcinoma (HCC) based on purchasing power parity (PPP) were USD 1625.50, USD 6117.2, and USD 11047.2 in 2015, respectively. CONCLUSIONS Chronic hepatitis C-related liver diseases impose a substantial economic burden on patients, families and the society. The current study provides useful information on cost of treatment and work loss for different disease states, which can be further used in cost-effectiveness evaluations.

Abstract
Chronic hepatitis C (CHC) is significantly associated with a risk of renal deterioration over time. Renal impairment, especially stage 4-5 chronic kidney disease, increases the risk of: (i) the prevalence and incidence (in dialysis/transplantation) of hepatitis C virus (HCV) infection; (ii) liver deterioration during kidney transplantation and (iii) allograft failure and patient mortality. HCV-infected dialysis patients have a higher mortality than non-infected dialysis patients and than HCV-infected kidney recipients. The harmful impact of HCV emphasizes the need for oral antiviral therapies in patients with chronic kidney disease. Symptomatic cryoglobulinemic vasculitis and extensive liver fibrosis are already approved indications for early access to oral antiviral treatment. Patients with stage 4-5 chronic kidney disease should also be given priority: dialysis patients (whatever the stage of fibrosis and whether or not they are candidates for kidney transplantation) as well as all kidney recipients. The results of treatment of HCV with direct-acting antiviral (DAAs) drugs in patients with late chronic kidney disease are excellent, similar to those in the general population, although additional clinical trials are definitely needed, particularly to optimize adjustment of treatment to kidney function and determine the risk of drug-drug interactions.

Abstract
INTRODUCTION A new form of hepatitis C virus infection, known as occult hepatitis C virus (HCV) infection, is characterized by the presence of HCV_RNA in the liver or peripheral blood mononuclear cells (PBMCs). However, no serological markers of infection occur and there is not as much damage to the liver damage as is produced by chronic hepatitis C. There is a high incidence of HCV infection among hemodialysis patients, there is significant concern about viral transmission. HCV infection is a major problem in hemodialysis (HD) units even though blood products are screened for anti-HCV antibodies and other precautions are taken. The aim of this study was to determine the prevalence of occult HCV infection in PBMC in chronic hemodialysis (CHD) patients in the dialysis unit at Theodor Bilharz Research Institute (TBRI) with HCV antibodies and HCV RNA negativity irrespective of their liver function tests. METHODS Fifty-three patients who were repeatedly were anti-HCV negative and serum HCV-RNA negative and on regular hemodialysis for > six months were enrolled in the study, which was conducted in the dialysis unit of Nephrology Department at TBRI; there were 10 healthy matched controls. The patients were classified into two groups according to the result HCV RNA in their PBMCs. Serological markers of HCV infection, including anti-HCV antibody and serum HCV-RNA, were repeatedly negative for all patients included in the study. We collected serum and PBMC samples from the patients on the day they entered the study. The test of all serum samples for anti-HCV antibodies and HCV-RNA was repeated by RT-PCR to ensure that the patients did not have these HCV serologic markers, We also measured their ALT and GGT levels. RESULTS Occult hepatitis C virus infection (OCI) was detected in 15.1% of our CHD patients without any evidence of chronic liver disease. CONCLUSION Occult HCV infection was present among the hemodialysis patients irrespective of whether they had persistent abnormal values of liver enzymes for which no cause had been identified. Further study is required to determine the clinical significance of occult HCV infections in these patients.

Abstract
L'hépatite C demeure la principale infection virale chez l'hémodialysé, dont la prise en charge thérapeutique ainsi que la gestion de ses effets secondaires restent difficiles. Il s'agit d'une étude rétrospective portant sur tous les patients atteints d'hépatite C chronique ayant une insuffisance rénale chronique sous hémodialyse, suivis au service de gastroentérologie au CHU Mohamed VI de Marrakech sur une période de Janvier 2004 à Décembre 2014. Sur un total de 355 cas d'hépatite virale C, 13 patients étaient hémodialysés (3,66%). Dix patients ont été traités, soit 76,94% des cas. Le traitement n’était pas indiqué chez 2 patients ayant une fibrose minime sans cytolyse. Il était contre-indiqué chez une patiente multitarée. Deux malades ont eu une réponse virologique rapide et 5 une réponse virologique précoce. Le taux de réponse virologique soutenue était de 40%, 30% des patients étaient non répondeurs. Le traitement fut arrêté chez 2 patientes pour effets secondaires sévères. Un seul patient a été candidat à une transplantation rénale. En analyse multivariée, la réponse virologique soutenue a été significativement associée à certains facteurs prédictifs de bonne réponse thérapeutique: Age jeune ≤40 ans (P=0,0057), fibrose minime F1-F2 (P=0,03), génotype non 1 (P=0,0064), charge virale préthérapeutique <800000 UI/ml (P=0,013), et l'absence d'arrêt thérapeutique (P=0,028). La gestion efficace des effets secondaires du traitement de HVC permet d'obtenir chez l'hémodialysé un taux de réponse virologique soutenue avoisinant celui de la population générale.

Abstract
Chronic infections by hepatitis B (HBV) and C virus (HCV) result in diagnosis and therapeutic issues in dialysis and kidney recipients patients. The exposure to nosocomial, including blood transfusion, risk explains the high prevalence of HBV and HCV infection in this setting. Chronic infection reduces the survival of both patients and allografts, including a specific risk of de novo glomerulonephritis. Cirrhosis was considered as a contra-indication to renal transplantation given the high risk of decompensation and death, questionning the indication of a combined liver and kidney transplantation. Thus, it is mandatory to screen HBV and HCV markers in all dialysis patients, whether or not they are candidates to transplantation. Liver biopsy allows evaluating the severity of the liver disease since the noninvasive markers of fibrosis appear to be less accurate in "renal" patients than in the general population and to better define antiviral therapeutic indications. HCV treatment was mainly based on pegylated interferon α (and low doses of ribavirin), which is contra-indicated in kidney recipients given the risk of graft rejection; HCV treatment is now based on the use of oral direct acting antivirals, which are very potent and well tolerated. HBV replication is now easily suppressed by second-generation nucleos(t)tidic analogues (entecavir and tenofovir), which will be indicated in all the dialysis patients with significant fibrosis (F2,3 or 4 according to the Metavir scoring system) and in any candidate to renal transplantation and to any HBsAg-positive kidney recipients. The best treatment remains preventive by anti-HBV vaccination for HBV and by the respect of universal hygiene rules for HCV.

Abstract
Hepatitis outbreaks in hemodialysis (HD) patients and staff were reported in the late 1960s, and a number of hepatotropic viruses transmitted by blood and other body fluids have been identified. Hepatitis B virus (HBV) was the first significant hepatotropic virus to be identified in HD centers. HBV infection has been effectively controlled by active vaccination, screening of blood donors, the use of erythropoietin and segregation of HBV carriers. Hepatitis delta virus is a defective virus that can only infect HBV-positive individuals. Hepatitis C virus (HCV) is the most significant cause of non-A, non-B hepatitis and is mainly transmitted by blood transfusion. The introduction in 1990 of routine screening of blood donors for HCV contributed significantly to the control of HCV transmission. An effective HCV vaccine remains an unsolved challenge; however, pegylation of interferon-alfa has made it possible to treat HCV-positive dialysis patients. Unexplained sporadic outbreaks of hepatitis by the mid-1990s prompted the discovery of hepatitis G virus, hepatitis GB virus C and the TT virus. The vigilant observation of guidelines on universal precaution and regular virologic testing are the cornerstones of the effective control of chronic hepatitis in the setting of HD. Major recent advances in the viral diagnosis technology and the development of new oral, direct-acting antiviral agents allow early diagnosis and better therapeutic response. The current update will review the recent developments, controversies and new treatment of viral hepatitis in HD patients.

Abstract
Objective:To identify the routes of transmission during an outbreak of infection with hepatitis C virus (HCV) genotype 2a/2c in a hemodialysis unit.Design:A matched case-control study was conducted to identify risk factors for HCV seroconversion. Direct observation and staff interviews were conducted to assess infection control practices. Molecular methods were used in a comparison of HCV infecting isolates from the case-patients and from patients infected with the 2a/2c genotype before admission to the unit.Setting:A hemodialysis unit treating an average of 90 patients.Patients:A case-patient was defined as a patient receiving hemodialysis with a seroconversion for HCV genotype 2a/2c between January 1994 and July 1997 who had received dialysis in the unit during the 3 months before the onset of disease. For each case-patient, 3 control-patients were randomly selected among all susceptible patients treated in the unit during the presumed contamination period of the case-patient.Results:HCV seroconversion was associated with the number of hemodialysis sessions undergone on a machine shared with (odds ratio [OR] per additional session, 1.3; 95% confidence interval [CI95], 0.9 to 1.8) or in the same room as (OR per additional session, 1.1; CI95, 1.0 to 1.2) a patient who was anti-HCV (genotype 2a/2c) positive. We observed several breaches in infection control procedures. Wetting of transducer protectors in the external pressure tubing sets with patient blood reflux was observed, leading to a potential contamination by blood of the pressure-sensing port of the machine, which is not accessible to routine disinfection. The molecular analysis of HCV infecting isolates identified among the case-patients revealed two groups of identical isolates similar to those of two patients infected before admission to the unit.Conclusions:The results suggest patient-to-patient transmission of HCV by breaches in infection control practices and possible contamination of the machine. No additional cases have occurred since the reinforcement of infection control procedures and the use of a second transducer protector.

Abstract
The advent of potent and safe direct-acting antivirals against the hepatitis C virus has the potential of fulfilling the dream of eliminating this infection and its impact on global public health. However, even if effective drugs are at hand, most patients remain unaware of their infection, which may be recognized only in late stages when dire complications have occurred. Europe is not spared by this scourge, with its estimated 19,000,000 persons infected, and knowledge of the epidemiology of HCV and its drivers is a critical tool in fighting this virus. A thorough review is provided on the extent of the HCV epidemic across Europe, with a discussion of the most important subgroups affected, and of the risk factors of infection, both traditional and new.

Abstract
Hepatitis C virus (HCV) infection is observed in around 20% of dialysis patients and in allograft recipients and results in a significant morbidity and mortality, especially after transplantation. Its prevalence has markedly decreased in patients who are candidates for transplantation since the introduction of screening, hygiene and prevention measures, including systematic screening of blood and organ donations, use of erythropoietin, and compliance with universal hygiene rules. A liver biopsy is preferable to non-invasive biochemical and/or morphological tests of fibrosis to evaluate liver fibrosis before and even after transplantation. In HCV-infected dialyzed patients who are not candidates for renal transplantation, the indication for antiviral therapy is limited to significant fibrosis (fibrosis ≥ 2 on the METAVIR scale). Antiviral treatment should be proposed to any HCV-infected candidate for renal transplantation, whatever the baseline histopathology. The recommendation is to use standard interferon-α as monotherapy, but pegylated interferon can be used, resulting in sustained virological response, while low doses of combined ribavirin may enhance the antiviral efficacy. After transplantation, interferon-α is contra-indicated but may be used in patients for whom the benefits of antiviral treatment clearly outweigh the risks, especially that of allograft rejection. All cirrhotic patients should be screened for hepatocellular carcinoma, whose risk is enhanced by immunosuppressive regimens. Sustained suppression of necro-inflammation may result in the reversal of cirrhosis, which reduces liver-related morbidity and improves patient and allograft survival. Finally, due to the high mortality after renal transplantation, active cirrhosis must be considered to be a contraindication to kidney transplantation, but an indication to combined liver-kidney transplantation; on the contrary, inactive compensated cirrhosis may permit renal transplantation alone.

Abstract
BACKGROUND AND AIM Viral hepatitis and human immunodeficiency virus (HIV) infection are important causes of morbidity and mortality in hemodialysis (HD) patients. The present study was performed to assess the prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV) and HIV infections in hemodialysis patients of a tertiary care hospital in Uttarakhand. METHODS All patients undergoing maintenance HD at our center were screened for hepatitis B surface antigen (HBsAg), antibody to HCV (anti-HCV), antibody to HDV (anti-HDV) and HIV antibody by ELISA. Detailed history regarding age, sex, duration of dialysis, blood transfusions, number of dialysis centers, dialyzer reuse and laboratory data was recorded. RESULTS A total of 118 patients (79 males and 39 females) were followed for 18 months with screening for the presence of HBV, HCV and HIV infections. At baseline, 12 (10.2%) patients were positive for HBsAg, 19 (16.1%) for anti-HCV and 2 (1.7%) for HIV antibody. Over 18 months, one additional patient became HBsAg positive and an additional 17 became anti-HCV-positive to give a total of 36 HCV-positive patients. Dual HBV and HCV infection was seen in 5 (4.2%) and anti-HDV antibodies were found in 1 (0.9%) patient. History of blood transfusions, duration of HD, dialyzer reuse and dialysis at multiple centers were found to be important risk factors for anti-HCV positivity. CONCLUSIONS Implementation and adherence to universal work precautions by dialysis staff is imperative to prevent transmission of these infections.

Abstract
BACKGROUND Evidence exists regarding the full prevention of HCV transmission to hemodialysis patients by implementing universal precaution. However, little information is available regarding the frequency with which hospitals have adopted evidence-based practices for preventing HCV infection among hemodialysis patients. A cross-sectional survey has been conducted among nurses in Calabria region (Italy) in order to acquire information about the level of knowledge, the attitudes and the frequencies of evidence-based practices that prevent hospital transmission of HCV. METHODS All 37 hemodialysis units (HDU) of Calabria were included in the study and all nurses were invited to participate in the study and to fill in a self-administered questionnaire. RESULTS 90% of the nurses working in HDU participated in the study. Correct answers about HCV pattern of transmission ranged from 73.7% to 99.3% and were significantly higher in respondents who knew that isolation of HCV-infected patients is not recommended and among those who knew that previous bloodstream infections should be included in medical record and among nurses with fewer years of practice. Most correctly thought that evidence-based infection control measures provide adequate protection against transmission of bloodborne pathogens among healthcare workers. Positive attitude was significantly higher among more knowledgeable nurses. Self-reporting of appropriate handwashing procedures were significantly more likely in nurses who were aware that transmission of bloodborne pathogens among healthcare workers may be prevented through adoption of evidence-based practices and with a correct knowledge about HCV transmission patterns. CONCLUSIONS Behavior changes should be aimed at abandoning outdated practices and adopting and maintaining evidence-based practices. Initiatives focused at enabling and reinforcing adherence to effective prevention practices among nurses in HDU are strongly needed.

Bashiri H, Omrani H, Mami M, Rezaee M. Comparison of contamination passing through Iranian and non- Iranian filters of ultra filtration dialysis machines in patients with hepatitis C. HEPATITIS MONTHLY 2013; 13:e5912. [PMID: 23483113 PMCID: PMC3589880 DOI: 10.5812/hepatmon.5912] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/12/2011] [Revised: 01/31/2012] [Accepted: 04/25/2012] [Indexed: 12/11/2022]
Abstract
BACKGROUND Hepatitis C is one of the common infectious diseases throughout the world. About 170 million people worldwide are infected with Hepatitis C virus. The most common route of transmission is direct blood-to-blood contacts. OBJECTIVES This study conducted to compare the amount of contamination might be found in ultra-filtered liquid passed through 2 kinds of filters ps10 (Mediatex, Iran) and Lups (Bio brand, Germany). PATIENTS AND METHODS To achieve the goal, infected dialysis patients in which hepatitis C virus infection was detected by Elisa and PCR were selected. RESULTS As shown in data the first stage of PCR test using ps10 filters all samples were negative. In the second step performed in later dialysis steps (with Lups filters), no infection was recorded, too. CONCLUSIONS Our results showed that dialysis machines do not have an important role in transmission of hepatitis C infection and sanitation control in the environment of dialysis should be emphasized.

Abstract
Hepatitis C virus infection is a perennial concern for hemodialysis units because the prevalence of hepatitis C is significantly higher there than in the general population. Through a systematic review and meta-analysis, we aim to assess the incidence rate of hepatitis C virus infection in hemodialysis units and explore its potential risk factors. Five electronic databases were used to search articles from 1990 to 2012, including PubMed, Embase, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, and Wanfang. A random-effects analysis was used to estimate the overall incidence rate of hepatitis C virus infection. A subgroup analysis and meta-regression analysis were conducted to explore factors associated with heterogeneity between studies. Twenty-two eligible articles were found, including 23 incidence rate estimates. The overall incidence rate of hepatitis C virus infection was 1.47 per 100 patient-years (95% confidence interval [CI] 1.14 to 1.80). In the subgroup analysis, the pooled incidence rate was 4.44 (CI 2.65, 6.23) per 100 patient-years in the developing world and 0.99 (CI 0.66, 1.29) per 100 patient-years in the developed world. [Correction added on 2 November 2012, after first online publication: Pooled incidence rate in the developed world has been changed.] In addition, in hemodialysis units with higher prevalence, the incidence rate of hepatitis C virus infection also tended to be higher. Meta-regression analysis showed that the country's development level and initial HCV prevalence combined could explain 67.91% of the observed heterogeneity. The incidence rate of hepatitis C virus infection among patients on hemodialysis was significantly high. Efforts should be taken to control hepatitis C virus infection in hemodialysis units, especially in developing countries.

Is early virological response as predictive of the hepatitis C treatment response in dialysis patients as in non-uremic patients? Int J Infect Dis 2012; 17:e50-3. [PMID: 23041364 DOI: 10.1016/j.ijid.2012.09.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2012] [Revised: 08/23/2012] [Accepted: 09/03/2012] [Indexed: 12/18/2022] Open
Abstract
OBJECTIVE The aim of the present study was to determine whether hepatitis C virus (HCV) RNA present at week 12 is a good predictor of the response to interferon (IFN) monotherapy in hemodialysis patients with hepatitis C. METHODS Hemodialysis patients with hepatitis C who were treated between 1997 and 2008 with IFN monotherapy for 48 weeks without dose reduction were included. The predictive value of HCV RNA at week 12 for achieving a sustained virological response (SVR) was determined. RESULTS Forty patients (mean age 47±9 years; 75% males and 80% with genotype 1) were included. Septal fibrosis or cirrhosis was observed in 38% of these patients. Twelve (30%) of the 40 patients achieved SVR. HCV RNA was undetectable at week 12 in 68%. The positive predictive value of HCV RNA at week 12 was 45% and the negative predictive value was 100%. CONCLUSIONS The presence of HCV RNA at week 12 had a high negative predictive value for SVR in hemodialysis patients with chronic hepatitis C treated with IFN for 48 weeks. Therefore, if HCV RNA is detected at week 12, treatment should be discontinued due to the low probability of a sustained response.

Abstract
We report the case of a 45-year-old haemodialysis patient who achieved a sustained virological response (SVR) following pegylated interferon therapy for hepatitis C virus (HCV) genotype 2 infection. He was subsequently cohorted with other HCV-infected dialysis patients and became re-infected with HCV genotype 3a. Epidemiological and molecular investigations identified a highly viraemic HCV genotype 3a-infected dialysis patient as the likely source of this infection. This critical incident informed a revision to local and national infection control policy regarding the dialysis management of patients who achieve an SVR following anti-viral treatment.

Abstract
Routine serological testing for hepatitis C virus (HCV) infection among hemodialysis (HD) patients is currently recommended. A dilemma existed on the value of serology because some investigators reported a high rate of false-negative serologic testing. In this study, we aimed to detect the false-negative rate of anti-HCV among Egyptian HD patients. Seventy-eight HD patients, negative for anti-HCV, anti-HIV, and hepatitis B surface antigen, were tested for HCV RNA by reverse transcriptase polymerase chain reaction (RT-PCR). In the next step, the viral load was quantified by real-time PCR in RT-PCR-positive patients. Risk factors for HCV infection, as well as clinical and biochemical indicators of liver disease, were compared between false-negative and true-negative anti-HCV HD patients. The frequency of false-negative anti-HCV was 17.9%. Frequency of blood transfusion, duration of HD, dialysis at multiple centers, and diabetes mellitus were not identified as risk factors for HCV infection. The frequency of false-negative results had a linear relation to the prevalence of HCV infection in the HD units. Timely identification of HCV within dialysis units is needed in order to lower the risk of HCV spread within the HD units. The high false-negative rate of anti-HCV among HD patients in our study justifies testing of a large scale of patients for precious assessment of effectiveness of nucleic acid amplification technology testing in screening HD patient.

Abstract
Transplantation is the best treatment for end-stage organ failure. Hepatitis virus infections, mainly hepatitis B virus (HBV) and hepatitis C virus (HCV) infections still constitute a major problem because they are common in allograft recipients and are a significant cause of morbidity and mortality after transplantation. Recently, hepatitis E virus infection has been added as an emergent cause of chronic hepatitis in organ transplantation. The prevalence of HBV and HCV infections has markedly decreased in patients who are candidates for transplantation since the introduction of screening, hygiene and prevention measures, including systematic screening of blood and organ donations, use of erythropoietin, compliance with universal hygiene rules, segregation of HBV-infected patients from non-infected patients and systematic vaccination against HBV. A liver biopsy is preferable to non-invasive biochemical and/or morphological tests of fibrosis to evaluate liver fibrosis before and even after transplantation. Treatment with entecavir or tenofovir is indicated in HBV-infected dialyzed patients who have moderate or severe disease (≥A2 or F2 on the Metavir scale) in preparation for renal transplantation. Due to the risks of severe reactivation, fibrosing cholestatic hepatitis or histological deterioration after transplantation, systematic use of nucleoside or nucleotide analogues shortly before or at the time of transplantation is recommended (tenofovir or entecavir are preferable to lamivudine) in all patients, whatever the baseline histological evaluation. In HCV-infected dialyzed patients who are not candidates for renal transplantation, the indication for antiviral therapy is limited to significant fibrosis (fibrosis ≥2 on the Metavir scale). Treatment must be proposed to all candidates for renal transplantation, whatever their baseline histopathology, and interferon-α should be used as monotherapy. After transplantation, interferon-α is contraindicated but may be used in patients for whom the benefits of antiviral treatment clearly outweigh the risks, especially that of allograft rejection. All cirrhotic patients, notably after solid organ transplantation, should be screened for hepatocellular carcinoma. Sustained suppression of necro-inflammation may result in regression of cirrhosis, which in turn may lead to decreased disease-related morbidity and improved survival. Finally, due to the high mortality after renal transplantation, active (namely without sustained viral suppression) cirrhosis should be considered a contraindication to kidney transplantation, but an indication to combined liver-kidney transplantation; on the contrary, inactive (namely with sustained viral suppression) compensated cirrhosis may permit renal transplantation alone. Organ transplantations other than kidney (cardiac or pulmonary transplantations) involve the same diagnosis and therapeutic issues.

Abstract
Hepatitis C virus (HCV) infection in hemodialysis (HD) is a significant problem. We evaluated the prevalence and associations of HCV viremia in our HD patients. All patients undergoing maintenance HD at our center were tested for HCV RNA by PCR after written informed consent. Detailed history regarding age, sex, and duration of dialysis, frequency of dialysis, blood transfusions in one year, number of dialysis centers, dialyzer reuse/fresh use, and recent laboratory data was recorded. A total of 119 patients (77 males and 42 females) were tested for HCV RNA. Thirty three (27.7%) tested positive. Duration of dialysis was significantly longer in HCV RNA positive group (P = 0.001). 45.2% of patients with duration of dialysis more than 16 months were HCV RNA positive while only 7.4% of patients with dialysis duration ≤16 months were HCV RNA positive (P < 0.001). In univariate analysis, in HCV RNA group patients, ALT, AST, and GGTP were significantly elevated and albumin was significantly lower. 39% of patients who had dialysis at more than one center were HCV RNA positive as compared to 20% for patients undergoing dialysis at single center (P = 0.024). Binary logistic regression analysis showed albumin, duration of dialysis, and serum ALT to be significant variables. Sensitivity and specificity of anti-HCV ELISA was 72.7 and 97.7%, respectively. Prevalence of HCV RNA in the HD population is 27.7%. Duration of dialysis, getting dialysis at more than one center, elevated transaminase levels, and low serum albumin are important associations for HCV RNA positivity.

Prevalence and incidence of hepatitis C virus in hemodialysis patients in British Columbia: Follow-up after a possible breach in hemodialysis machines. CANADIAN JOURNAL OF INFECTIOUS DISEASES & MEDICAL MICROBIOLOGY 2011; 20:e19-23. [PMID: 20514154 DOI: 10.1155/2009/641941] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 01/22/2008] [Accepted: 09/04/2008] [Indexed: 01/20/2023]
Abstract
BACKGROUND A possible breach of the transducer protector in specific dialysis machines was reported in June 2004 in British Columbia (BC), which led to testing of hemodialysis patients for hepatitis C virus (HCV), hepatitis B virus (HBV) and HIV. This testing provided an opportunity to examine HCV incidence, prevalence and coinfection with HBV and HIV, and to compare anti-HCV and HCV polymerase chain reaction (PCR). METHODS The results of hemodialysis patients who were dialyzed on the implicated machines (65% of BC dialysis patients), and tested for HCV, HBV and HIV, between June 1, 2004, and December 31, 2004, were reviewed and compared with available previous results. RESULTS Of 1286 hemodialysis patients with anti-HCV and/or HCV-PCR testing, 69 (5.4%) tested positive. Two HCV genotype 4 seroconversions were identified. HCV incidence rate on dialysis was 78.8 cases per 100,000 person-years. Younger age, history of renal transplant and past HBV infection were associated with HCV infection. No occult infection was identified using HCV-PCR. INTERPRETATION Hemodialysis patients had three times the HCV prevalence rate of the general BC population, and more than 20 times the incident rate of the general Canadian population. One of the two seroconversions occurred before the testing campaign; the patient was likely infected during hemodialysis in South Asia. The other was plausibly a late seroconversion following renal transplant in South Asia. Nosocomial transmission cannot be ruled out because both patients were dialyzed in the same centre. Baseline and annual anti-HCV testing is recommended. HCV-PCR should be considered at baseline for persons with HCV risk factors, and for returning travellers who received dialysis in HCV-endemic countries to identify HCV infection occurring outside the hemodialysis unit.
