Abstract
OBJECTIVES Carpal tunnel syndrome (CTS) is a common complication in maintenance hemodialysis (MHD) patients and leads to disabilities and increased risk of mortality. Hepatitis C virus (HCV) infection is associated with inflammatory and oxidative stress, and HCV infection can be cured. This study aimed at evaluating the association of HCV infection with CTS. METHODS Using a cross-sectional design, anthropometric and laboratory data were collected. Serum β2-microglobulin, HCV antibody and HCV-RNA were measured. CTS was diagnosed according to clinical manifestation, electrophysiological test or ultrasonography. The related factors for CTS were analyzed by multivariate logistic regression. RESULTS This study included 113 participants, of whom 33 (29.2%) patients were positive for HCV antibody and 18 (15.9%) were positive for HCV antibody and HCV-RNA. Thirty-two (28.3%) patients were diagnosed with CTS. There were significant differences in the dialysis vintage, age of onset of MHD, high-sensitivity C-reactive protein, serum β2M, anti-HCV-positive, HCV-RNA-positive, HCV load values and urine volume category between the CTS group and non-CTS group (p < 0.05). High-sensitivity C-reactive protein (OR: 1.238, 95% CI: 1.071-1.431, p = 0.004), dialysis vintage (OR: 1.017, 95% CI: 1.008-1.026, p < 0.001) and HCV-RNA-positive (OR: 5.929, 95% CI: 1.295-27.132, p = 0.022) rather than anti-HCV-positive were related factors for CTS. CONCLUSIONS High-sensitivity C-reactive protein, dialysis vintage and HCV-RNA replication but not previous HCV-infection were related factors for CTS in MHD patients. Further studies are needed to clarify whether intervention is beneficial for preventing and delaying the progression of CTS in MHD patients with HCV-RNA replication.

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

Abstract
Hepatitis C virus (HCV) infection is common among hemodialysis (HD) patients and has been recognized as an important prognostic factor. Therefore, the aggressive antiviral therapy is necessary for HCV infection in HD patients. However, various treatment limitations exist in HD patients such as the inability to use ribavirin. We have previously reported that HCV RNA can be eradicated by administration of interferon (IFN)-β during HD in patients with HCV infection caused by genotypes known to be sensitive to IFN therapy and low serum HCV RNA levels. In this case report, we tried to clarify the efficacy of combined application of double-filtration plasmapheresis (DFPP) and IFN-β in HD patients with HCV genotype 1b infection and high serum HCV RNA levels. We report two HD patients with HCV genotype 1b infection and high viral loads who were successfully treated by five sessions of DFPP undertaken prior to treatment with IFN-β (twice-daily injections for 2 weeks). HCV was eradicated by this combination therapy in both patients. We revealed the efficacy of combined application of DFPP and IFN-β in HD patients with HCV genotype 1b infection and high serum HCV RNA levels. This combined therapy may be useful for the HD patients who are resistant to conventional IFN monotherapy.

Abstract
BACKGROUND While there is a recognized risk of hepatitis C acquisition associated with dialysis away from the "home" center, there is little documented data on the effect that dialysis while traveling has on the dialysis patient's health. This study was designed to examine the incidence of travel within a hemodialysis population and to ascertain whether travel was associated with morbidity for patients on hemodialysis. METHODS Travel data were collected prospectively over a 6-month period, from April 2009, for all patients receiving maintenance hemodialysis across our dialysis centers. Biochemical, microbiological, and hematological parameters as well as hepatitis serology and antibiotic starts were recorded for 12 weeks prior to and following dialysis away from center. RESULTS A total of 172 individuals traveled on 200 occasions. The blood stream infection rate for travelers with a central venous catheter was 0.25 versus 0.83/1,000 access days (p = 0.038) in the 12 weeks pre-travel versus post-travel. Parenteral and oral antibiotic starts were both significantly elevated post-travel and were mainly instituted for either chest or urinary sepsis. There was evidence of raised inflammatory markers and anemia on return to center but no evidence of hepatitis B or hepatitis C seroconversion. CONCLUSIONS Travel and dialysis away from a patient's usual hemodialysis unit is a common occurrence but is associated with an increased risk of bacterial infection, anemia, and inflammatory response. This study provides evidence for the concern that hemodialysis away from center is associated with increased morbidity.

Abstract
BACKGROUND The prevalence of hepatitis viruses in hemodialysis patients has been reported to be much greater than in the general population. Attention to local data, effectively guides health planners so that they can control infections and prevent nosocomial transmissions. OBJECTIVES This cross sectional study was carried out to determine the prevalence of hepatitis B (HBV), hepatitis C (HCV), and hepatitis D (HDV) viruses, as well as the human immunodeficiency virus (HIV) in dialysis centers in the Kerman Province, in the southeast of Iran. PATIENTS AND METHODS All hemodialysis patients (n = 228) in 7 centers were enrolled in the study. Hepatitis B surface antigens (HBsAg), HCV antibodies (Ab), HDV Ab and HIV Ab were measured using specific enzyme linked immunoassay kits (ULTRA kit, bioMérieux, France) and confirmed by a qualitative PCR assay. RESULTS The studied group was comprised of 92 (40.4%) females and 136 (59.6%) males. The mean age of the patients was 51 ± 9.5 years and the duration of hemodialysis was 39.7 ± 7.9 months. Positive HBsAg was found in 7% of cases, HCV Ab in 7%, and patients with both viruses were detected in 1.7% cases. HIV Ab and HDV Ab were negative in all cases. Out of the other risk factors, frequency of blood transfusions was significantly correlated with positive HCV Ab (P < 0.008). CONCLUSIONS Prevalence of HBV and HCV in hemodialysis patients was moderate to low in the Kerman Province, as in other parts of the country. Strict adherence to protective measures could lead to even lower rates.

Abstract
Background Carpal tunnel syndrome (CTS) is the most common complication of dialysis-related amyloidosis (DRA) developing in patients on long-term dialysis therapy. The aim of this study was to evaluate the incidence of CTS and identify factors influencing the development of CTS in patients on maintenance hemodialysis, as well as results of its surgical treatment. Material/Methods The study included 386 patients, among whom CTS was diagnosed in 40 patients (10.4%) on the basis of signs and physical symptoms, as well as by nerve conduction. The group of patients with CTS and the group of patients without CTS were compared according to age (mean 54.50 vs. 56.48 years) and duration of dialysis treatment. Initial analysis of CTS incidence by sex, presence of anti-HCV antibodies, and location of arterio-venous fistula (AV fistula) was undertaken. Results Duration of dialysis treatment was the statistically significant risk factor for the development of CTS (16.05 vs. 4.51 years; p<0.0001). Among patients treated for a long period on hemodialysis (20–30 years), 100% required surgical release procedures, while 66.66% of those treated for 15–19 years, 42.1% of those treated for 10–14 years, and 1.6% of those treated for less than 10 years. CTS was diagnosed more often in anti-HCV-positive patients as compared with anti-HCV-negative patients (47.5 vs. 6.9%; p<0.0001). No significant differences were found when comparing CTS incidence by sex or between the development of CTS requiring surgical release intervention and location of the AV fistula. Conclusions Surgical release procedure of the carpal tunnel gave good treatment results in patients with CTS.

Abstract
BACKGROUND AND OBJECTIVES Hepatitis C virus (HCV) infection is associated with increased mortality and morbidity in end-stage renal failure (ESRF) patients. Despite a lower incidence and risk of transmission of HCV infection with peritoneal dialysis (PD), the optimal dialysis modality for HCV-infected ESRF patients is not known. The aim of this study was to evaluate the impact of dialysis modality on the survival of HCV-infected ESRF patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The study included all adult incident ESRF patients in Australia and New Zealand who commenced dialysis between January 1, 1994, and December 31, 2008, and were HCV antibody-positive at the time of dialysis commencement. Time to all-cause mortality was compared between hemodialysis (HD) and PD according to modality assignment at day 90, using Cox proportional hazards model analysis. RESULTS A total of 424 HCV-infected ESRF patients commenced dialysis during the study period and survived for at least 90 days (PD n = 134; HD n = 290). Mortality rates were comparable between PD and HD in the first year (10.7 versus 13.8 deaths per 100 patient-years, respectively; adjusted hazard ratio [HR] 0.65, 95% CI 0.34 to 1.26) and thereafter (20 versus 15.9 deaths per 100 patient-years, respectively; HR 1.27, 95% CI 0.86 to 1.88). CONCLUSIONS The survival of HCV-infected ESRF patients is comparable between PD and HD.

Abstract
CONTEXTO: Doentes com doença renal crônica em tratamento hemodialítico apresentam risco aumentado de aquisição do vírus da hepatite C (VHC). Elevadas taxas de prevalência têm sido detectadas em unidades de diálise do mundo inteiro. Estudos recentes têm demonstrado que a infecção pelo VHC interfere de forma negativa na sobrevida dos pacientes em hemodiálise e naqueles submetidos ao transplante renal. OBJETIVOS: Determinar a prevalência e os fatores de risco da infecção pelo VHC em pacientes submetidos a hemodiálise. MÉTODOS: Realizou-se estudo transversal entre janeiro e dezembro de 2007. Neste período, 236 pacientes em hemodiálise foram testados pelo ELISA de terceira geração. Os casos positivos foram submetidos a pesquisa qualitativa do HCV-RNA pelo método de PCR. Consideraram-se como portadores de infecção pelo VHC aqueles pacientes com anti-VHC e HCV-RNA positivos. Dosagens mensais de ALT e a média do valor de 12 meses foram obtidas em 195 pacientes. Do total de pacientes, 208 (88,1%) responderam ao questionário padronizado visando a identificação de fatores de risco associados à infecção pelo VHC. RESULTADOS: A prevalência de pacientes anti-VHC positivos encontrada entre os 236 testados foi de 14,8% (35/236); destes, a pesquisa do HCV-RNA foi positiva em 71,6% (25/35). Portanto, a prevalência da infecção crônica pelo VHC foi de 10,6% (25/236) dos pacientes. Pela análise bivariada, os principais fatores de risco associados à infecção pelo VHC foram o tempo de hemodiálise, o número de transfusões de sangue, a realização prévia de diálise peritonial e história de doença sexualmente transmissível. Contudo, após análise multivariada, somente o tempo de hemodiálise e história de doença sexualmente transmissível foram significativamente associados à infecção pelo VHC. Pacientes com mais de 10 anos de hemodiálise apresentaram risco de aquisição do VHC 73,9 (IC de 17,5 a 311,8) vezes maior quando comparados a pacientes com até 5 anos de tratamento. Indivíduos com doença sexualmente transmissível prévia apresentaram risco 4,8 (IC de 1,1 a 19,9) vezes superior de contaminação pelo VHC quando comparados àqueles sem doença sexualmente transmissível. O valor médio da ALT foi significantemente maior nos pacientes infectados pelo VHC (44,0 ± 13,5 U/L versus 33,5 ± 8,0 U/L, P<0,001). CONCLUSÃO: A infecção pelo VHC apresentou elevada prevalência na unidade de diálise analisada. O tempo de tratamento dialítico e história prévia de doença sexualmente transmissível foram os principais fatores de risco associados à infecção pelo VHC. Indivíduos em hemodiálise com infecção crônica pelo VHC apresentaram maior atividade de ALT que pacientes sem hepatite C crônica.

Abstract
To determine the prevalence and incidence of hepatitis C virus (HCV) infections among haemodialysis patients, a large prospective multicentre trial was conducted in the German Federal State of North Rhine-Westphalia. Sera obtained from the recruited patients in two separate sampling rounds run 1 year apart were analysed for both anti-HCV antibodies and HCV RNA. HCV RNA positive samples were also genotyped by direct sequencing of an HCV core fragment. In the first and second rounds, 150 (5.2%) of 2909 and 114 (5.4%) of 2100 patients were anti-HCV positive, respectively, and 4% of individuals were viraemic. Evaluation of potential risk factors in a case-control study indicated that the factors 'foreign country of birth', 'blood transfusions given before 1991' and 'duration of treatment on haemodialysis' were associated with the risk of HCV infection. Among the 2100 patients of whom 'paired' serum samples from both rounds were available for testing, not a single 'de novo' HCV infection could be recorded. The fact that in a subset of about 20% of these patients no nosocomial GB virus C (GBV-C) transmission occurred during the observational period suggests that the lack of HCV seroconversions was not only attributable to the isolation of HCV-infected patients but also to the strict adherence to so-called universal hygienic precautions for infection control maintained in the participating dialysis centres.

Abstract
Large public health interventions to control infectious disease outbreaks are common, but rigorous evaluation to improve the quality and effectiveness of these is rarely undertaken. This project aimed to prevent blood borne virus (BBV) cross-transmission in dialysis units. Following an incident concerning the diagnosis of acute Hepatitis B in a haemodialysis patient, possibly from healthcare associated acquisition, a multifaceted and multidisciplinary investigation was conducted involving consumers, health professionals and administrations. The results of this investigation were then used to produce practical operational guidelines for planning and future interventions. To date, there has been no incidence reported of any cross-transmission of BBV amongst our dialysis population. The actions implemented can be utilised by other departments in preventing other bacterial or viral outbreaks.

Abstract
BACKGROUND The impact of dialysis modality on the rates and types of infectious complications has not been well studied. The aim of the present investigation was to evaluate the rates of hepatitis C virus (HCV) and hepatitis B virus (HBV) infections in peritoneal dialysis (PD) and haemodialysis (HD) patients in the Asia-Pacific region. METHODS The study included the most recent period-prevalent data recorded in the national or regional dialysis registries of the 10 Asia-Pacific countries/areas (Australia, New Zealand, Japan, China, Taiwan, Korea, Thailand, Hong Kong, Malaysia and India), where such data were available. Longitudinal data were also available for all incident Australian and New Zealand patients commencing dialysis between 1 April 1995 and 31 December 2005. Rates of HCV and HBV infections were compared by chi-square, Poisson regression and Kaplan-Meier survival analyses, as appropriate. RESULTS Data were obtained on 201,590 patients (HD 173,788; PD 27,802). HCV seroprevalences ranged between 0.7% and 18.1% across different countries and were generally higher in HD versus PD populations (7.9% +/- 5.5% versus 3.0% +/- 2.0%, P = 0.01). Seroconversion rates on dialysis were also significantly higher in HD patients (incidence rate ratio PD versus HD 0.33, 95% CI 0.13-0.75). HCV infection was highly predictive of mortality in Japan (relative risk 1.37, 95% CI 1.15-1.62, P = 0.003) and in Australia and New Zealand (adjusted hazards ratio 1.29, 95% CI 1.05-1.58). HBV infection data were limited, but less clearly influenced by dialysis modality. CONCLUSIONS Dialysis modality selection significantly influences the risk of HCV infection experienced by end-stage renal failure patients in the Asia-Pacific region. No such association could be identified for HBV infection.
