Abstract
Hepatitis C virus (HCV) infection can lead to hepatic fibrosis. The advent of direct-acting antivirals (DAAs) has substantially improved sustained virological response (SVR) rates. In this context, kidney transplant recipients (KTRs) are of particular interest due to their higher HCV infection rates and uncertain renal excretion and bioavailability of DAAs. We investigated liver stiffness after DAA treatment in 15 HCV-infected KTRs using ultrasound shear wave elastography (SWE) in comparison with magnetic resonance elastography (MRE). KTRs were treated with DAAs (daclatasvir and sofosbuvir) for three months and underwent SWE at baseline, end of therapy (EOT), and 3 (EOT+3) and 12 months (EOT+12) after EOT. Fourteen patients achieved SVR12. Shear wave speed (SWS)-as a surrogate parameter for tissue stiffness-was substantially lower at all three post-therapeutic timepoints compared with baseline (EOT: -0.42 m/s, p < 0.01; CI = -0.75--0.09, EOT+3: -0.43 m/s, p < 0.01; CI = -0.75--0.11, and EOT+12: -0.52 m/s, p < 0.001; CI = -0.84--0.19), suggesting liver regeneration after viral eradication and end of inflammation. Baseline SWS correlated positively with histopathological fibrosis scores (r = 0.48; CI = -0.11-0.85). Longitudinal results correlated moderately with APRI (r = 0.41; CI = 0.12-0.64) but not with FIB-4 scores (r = 0.12; CI = -0.19-0.41). Although higher on average, SWE-derived measurements correlated strongly with MRE (r = 0.64). In conclusion, SWE is suitable for non-invasive therapy monitoring in KTRs with HCV infection.

Abstract
Hepatitis C virus (HCV) infection causes hepatic and extrahepatic organ involvement. Chronic kidney disease (CKD) is a prevalent non-communicable disorder, accounting for significant morbidity and mortality worldwide. Acute kidney injury and CKD are not uncommon sequels of acute or chronic HCV infection. The pathogenesis of HCV-associated kidney injuries is not well explored. Excess cryoglobulin production occurs in HCV infection. The cryoglobulin may initiate immune complex-mediated vasculitis, inducing vascular thrombosis and inflammation due to cryoglobulin deposits. Furthermore, direct damage to nephron parts also occurs in HCV patients. Other contributory causes such as hypertension, diabetes, and genetic polymorphism enhance the risk of kidney damage in HCV-infected individuals. Implementing CKD prevention, regular evaluation, and therapy may improve the HCV burden of kidney damage and its related outcomes. Therefore, in this review, we discuss and update the possible mechanism(s) of kidney injury pathogenesis with HCV infection. We searched for related published articles in EMBASE, Google Scholar, Google, PubMed, and Scopus. We used various texts and phrases, including hepatitis virus and kidney, HCV and CKD, kidney pathology in viral hepatitis, kidney transplantation in HCV-infected patients, kidney allograft survival in viral hepatitis patients, mechanism of kidney pathology in viral hepatitis, dialysis and viral hepatitis, HCV infection and kidney injuries, and viral hepatitis and CKD progression, etc. to identify relevant articles.

Abstract
Chronic kidney disease (CKD), hepatitis B virus (HBV), and hepatitis C virus (HCV) have a high prevalence in Oman. This study aimed to examine the association between CKD and viral hepatitis through an observational cohort study conducted at the Royal Hospital of the Sultanate of Oman to evaluate the relationship of HBV and HCV with CKD. During the study, 233 patients were identified, 112 with chronic HBV (Group 1), 112 with chronic HCV (Group 2), and nine with HBV and HCV coinfection (Group 3). The population was predominantly male, especially in Groups 1 and 3. The difference in age between Groups 1 and 2 was significant, with the mean age being 48 ± 14.6 years and 55 ± 12.6 years, respectively (P <0.05). This study revealed that the prevalence of CKD in Group 1 is 51%, in Group 2 was 78%, and in Group 3 was 56%. The mean estimated glomerular filtration rate (eGFR) was 79.7 mL/min/1.73 m2 in Group 1, 73.2 mL/min/1.73 m2 in Group 2, and 57.6 mL/min/1.73 m2 in Group 3. CKD had the highest prevalence in Group 2. The lowest eGFR was found in Group 3. Group 2 showed the highest rate of declining renal function over time despite treatment. This study found a significant and independent association between viral hepatitis and the risk of CKD, especially in cases of coinfection and HCV infection. This warrants close monitoring of kidney function during screening and follow-up. Patients with CKD should be screened for viral hepatitis.

Abstract
Background Direct-acting antivirals (DAA) are highly effective at treating Hepatitis C virus (HCV) infection, with a cure rate >95%. However, the effect of DAAs on kidney function remains debated. Methods We analyzed electronic health record data for DAA-naive patients with chronic HCV infection engaged in HCV care at Boston Medical Center between 2014 and 2018. We compared the following hypothetical interventions using causal inference methods: 1) initiation of DAA and 2) no DAA initiation. For patients with normal kidney function at baseline (eGFR>90 ml/min/1.73m2), we estimated and compared the risk for reaching Stage 3 chronic kidney disease (CKD) (eGFR≤60 ml/min/1.73m2) under each intervention. For patients with baseline CKD Stages 2–4 (15<eGFR≤90 ml/min/1.73m2), we estimated and compared the mean change in eGFR at 2 years after baseline under each intervention. We used the parametric g-formula to adjust our estimates for baseline and time-varying confounders. Results First, among 1390 patients with normal kidney function at baseline the estimated 2-year risk difference (95% CI) of reaching Stage 3 CKD for DAA initiation versus no DAA was -1% (-3, 2). Second, among 733 patients with CKD Stage 2–4 at baseline the estimated 2-year mean difference in change in eGFR for DAA initiation versus no DAA therapy was -3 ml/min/1.73m2 (-8, 2). Conclusions We found no effect of DAA initiation on kidney function, independent of baseline renal status. This suggests that DAAs may not be nephrotoxic; furthermore, in the short-term, HCV clearance may not improve CKD.

Abstract
HCV is a virus that can cause chronic infection which can result in a systemic disease that may include many rheumatologic manifestations such as arthritis, myalgia, sicca syndrome, cryoglobulinemia vasculitis as well as other non-rheumatological disorders (renal failure, onco-haematological malignancies). In this population, the high frequency of rheumatoid factor (45-70%), antinuclear (10-40%) and anticardiolipin (15-20%) antibodies is a B-cell mediated finding sustained by the infection. However, the possibility that a primitive rheumatic pathology may coexist with the HCV infection is not to be excluded thus complicating a differential diagnosis between primitive and HCV-related disorders.

Abstract
BACKGROUND The association between hepatitis C virus (HCV) infection and chronic kidney disease (CKD) still remains controversial. We aimed to investigate whether HCV really affects renal function, and to analyze the association between clinical effects of CHC and decreased kidney function (assessed by glomerular filtration rate (eGFR) level). METHODS An estimated 3360 patients with HCV infection and 3360 age- and sex-matched community-based control individuals without HCV were enrolled (1:1, case and control ratio) in this study between 2004 and 2016. We used the modification of diet in renal diseases to calculate eGFR. Demographic and laboratory parameters were assessed, and appropriate statistical methods were performed for the analysis. RESULTS Multivariate logistic regression analysis revealed that serum alanine aminotransferase level (odds ratio [OR] 0.998; 95% confidence interval [CI] 0.997-0.999; P = 0.001), platelet count (OR 0.997; 95% CI 0.995-0.999; p = 0.002), and hypertension (OR 1.31; 95% CI 1.03-1.66; P = 0.027) were significantly associated with HCV infection and serum triglyceride levels (OR 1.001; 95% CI 1.00-1.002; p = 0.005), platelet count (OR 0.996; 95% CI 0.995-0.997; p < 0.001), body mass index (BMI) >25 (OR 1.43; 95% CI 1.23-1.67; p < 0.001), hypertension (OR 1.69; 95% CI 1.42-1.99; p < 0.001), hyperlipidemia (OR 1.32; 95% CI 1.02-1.71; p = 0.035), and diabetes (OR 1.33; 95% CI 1.03-1.71; p = 0.032) were significantly associated with a low eGFR (<90 mL/min/m3) in control subjects. The BMI >25 kg/m2, hypertension, and diabetes were found to be associated with low eGFR interaction with the HCV infection, via a multivariate analysis. CONCLUSION Our study found that the patients with HCV infection are associated with a low eGFR compared with non-HCV-infected patients. This association is consistent in obese, diabetic, and hypertensive patients.

Abstract
Chronic kidney disease (CKD) is one of the most well-known extrahepatic manifestations caused by hepatitis C infection (HCV). CKD is typically discovered at a late stage. HCV-nephropathy may show different histopathologic patterns, as both glomerular and tubulointerstitial damage have been described. Identification of patients with early renal manifestations would be beneficial to provide treatment and avoid progression to CKD. The observational prospective single-center HCVKID study assessed the prevalence of early renal manifestations in patients with chronic HCV and compared these patients with HCV-negative healthy controls cross-sectionally. HCV-positive patients with and without renal manifestations were also compared to define biomarkers suitable for identifying early manifestations in standard clinical practice. Tubular proteinuria as judged by urine α 1-microglobulin was the most common early renal manifestation found in 11% in HCV-positive patients, followed by hematuria in 8%. Kidney filtration was statistically significantly lower among HCV-positive patients with renal manifestation according to any calculation method. There were no significant differences in duration of infection or stage of liver fibrosis between patients with or without renal manifestations. Tubular cell damage may be the earliest sign of renal dysfunction caused by HCV. Complement activation also correlates with the dysfunction, indicating of contribution to HCV-induced renal manifestations even in their early phase.

PURPOSE OF REVIEW Direct acting antiviral agents (DAAs) have emerged as simple, short, safe, and effective treatments for chronic hepatitis C (CHC) infection. CHC is a systemic disease with frequent and multiple extrahepatic manifestations. The beneficial effects of DAA treatment regimens extend beyond improvement in liver-related outcomes to amelioration of extra hepatic manifestations and are likely to have economic implications. The purpose of this review is to evaluate the effect of DAAs on extra hepatic manifestations of CHC virus infection. RECENT FINDINGS Recent studies indicate that DAAs are associated with reduction in all-cause mortality, even in patients without significant hepatic fibrosis. They are also associated with reduction in incident cardiovascular disease and diabetes. DAAs are the mainstay of treatment in HCV-associated cryoglobulinemia and lymphoma. Successful HCV therapy with DAAs also improves patient-related outcomes such as health-related quality of life. DAAs improve extrahepatic manifestations of CHC virus infection. Future studies are needed to evaluate the long-term durability of treatment response and for accounting amelioration of extrahepatic manifestations into the cost effectiveness of DAA regimens.

Abstract
The first KDIGO (Kidney Disease: Improving Global Outcomes) guideline for the prevention, diagnosis, evaluation, and treatment of hepatitis C virus (HCV) infection was published in 2008. The ensuing decade bore witness to remarkable advances in the treatment of HCV infection following the approval of direct-acting antiviral (DAA) agents that deliver cure rates routinely >95%. In this context, the KDIGO organization correctly recognized the need for an updated HCV guideline that would be relevant to the treatment of HCV-infected patients with kidney disease in the DAA era. The current NKF-KDOQI (National Kidney Foundation-Kidney Disease Outcomes Quality Initiative) commentary provides an in-depth review and perspective on the 2018 KDIGO guideline. Of note, the KDIGO work group made significant updates to guideline chapters 2 and 4 as a direct result of the availability of DAAs. The intent of this commentary is to provide useful interpretation for nephrologists and other practitioners caring for HCV-infected patients with chronic kidney disease, including dialysis patients and kidney transplant recipients. The availability of DAA agents that are safe and highly effective has created new opportunities, such as the transplantation of kidneys from HCV-infected kidney donors. The ability to treat HCV infection in patients with kidney disease will have a significant impact on the care of our patients and should favorably influence long-term outcomes as well.

Abstract
Beyond the classic hepatic complications, hepatitis C (HCV) infection is considered as a systemic disease, since extrahepatic manifestations become clinically evident in 40% to 70% of the patients and it can frequently include rheumatic ones. Furthermore, HCV can promote the production of several autoantibodies, thus complicating the differential diagnosis between primitive and HCV-related rheumatic disorders. The recent development of direct-acting antivirals (DAA) against HCV has revolutionized the field, reducing the damage stemming from systemic inflammatory phenomena and persistent immune activation associated with continuous HCV replication. Our review focuses on the main rheumatologic manifestations associated with chronic HCV infection as well as the impact of DAA interferon-free treatments on such extrahepatic clinical involvement.

Abstract
Hepatitis C virus (HCV) infection is common and can accelerate chronic kidney disease (CKD) progression. Direct-acting antiviral (DAA) therapies against hepatitis C have consistently shown rates of sustained viral remission. However, the effect on kidney function is unknown. In a retrospective observational cohort study of HCV-infected patients receiving DAA therapies from 2013 to 2017, the slopes of estimated glomerular filtration rate (eGFR) decline were compared in the three years before DAA therapy to the slope after therapy. Pre- and post-treatment albuminuria values were also compared. In all, 1,178 patients were included; mean age of 56, 64% male, 71% white, 21% were diabetic, and 42% with cirrhosis. In patients with eGFR less than 60ml/min per 1.73m2, the annual decline in eGFR in the three years prior to treatment was -5.98 ml/min per year (95% confidence interval -7.30 to -4.67) and improved to -1.32 ml/min per year (95% confidence interval -4.50 to 1.88) after DAA therapy. In patients with eGFR greater than 60ml/min per 1.73m2 the annual decline in eGFR in the three years prior to treatment was -1.43 ml/min per year (95% confidence interval -1.78 to -1.08) and after DAA therapy was -2.32 ml/min per year (95% confidence interval -3.36 to -1.03). Albuminuria improved significantly in patients without diabetes, but not in those with diabetes. Predictors of eGFR improvement included having CKD at baseline and being non-diabetic. Events of acute kidney injury were rare, occurring in 29 patients, and unrelated to antiviral therapy in 76% of cases. Thus, DAA therapy for HCVs infection may slow CKD progression.

Abstract
INTRODUCTION AND AIM The role of hepatitis C virus infection as a risk factor for the development and progression of chronic kidney disease in the general population remains unclear. MATERIAL AND METHODS A systematic review of the published medical literature was performed to assess whether positive anti-HCV serologic status is associated with higher frequency of chronic kidney disease in the adult general population. We used a random-effects model to generate a summary estimate of the relative risk of chronic kidney disease (defined by lowered glomerular filtration rate or detectable proteinuria) with HCV across the published studies. Meta-regression and stratified analysis were also carried out. RESULTS Forty studies were eligible (n = 4,072,867 patients), and separate meta-analyses were conducted according to the outcome. Pooling results of longitudinal studies (n = 15 studies, n = 2,299,134 unique patients) demonstrated an association between positive anti-HCV serologic status and increased incidence of CKD, the summary estimate for adjusted HR with HCV across the surveys, 1.54 (95% CI, 1.26; 1.87) (P < 0.001). Between-study heterogeneity was observed (Q value by Chi-squared [χ2] test 500.3, P < 0.0001). The risk of chronic kidney disease related to HCV, in the subset of surveys from Asia was 1.45 (1.27; 1.65) (P < 0.001) (no heterogeneity). According to our meta-regression, ageing (P < 0.0001) and duration of follow-up (P < 0.0001) increased the risk of chronic kidney disease among HCV-positive subjects. We observed a relationship between anti-HCV positive serologic status and frequency of proteinuria, adjusted effect estimate of proteinuria with HCV among surveys was 1.633 (95% CI, 1,29; 2.05) (P < 0.001) (n = 10 studies; 315,404 unique patients). However, between-studies heterogeneity was noted (P value by Q test < 0.0001). CONCLUSION An association between HCV infection and increased risk of chronic kidney disease in the general population exists. The mechanisms underlying such association are currently under active investigation.

Abstract
Hepatitis C virus (HCV) infection unfavorably affects the survival of both renal patients undergoing hemodialysis and renal transplant recipients. In this subset of patients, the effectiveness and safety of different combinations of interferon-free direct-acting antiviral agents (DAAs) have been analyzed in several small studies. Despite fragmentary, the available data demonstrate that DAA treatment is safe and effective in eradicating HCV infection, with a sustained virologic response (SVR) rates nearly 95% and without an increased risk of allograft rejection. This review article analyzes the results of most published studies on this topic to favor more in-depth knowledge of the readers on the subject. We suggest, however, perseverating in this update as the optimal DAA regimen may not be proposed yet, because of the expected arrival of newer DAAs and of the lack of data from large multicenter randomized controlled trials.

Abstract
Hepatitis C virus (HCV) infection greatly increases the risk of nephropathy. In this observational study, we aimed to explore the relationship between viral hepatitis infection and chronic kidney disease (CKD), identify risk factors, and determine the effect of antiviral treatment on CKD in Chinese patients with chronic HCV infection. A total of 2,435 study subjects were enrolled and divided into four groups: the HCV infection, HBV infection, HBV and HCV co-infection, and uninfected control groups. Of these, 207 patients with chronic hepatitis C (CHC) were given standard dual therapy [subcutaneous injection of recombinant interferon (IFN)-α2b and oral ribavirin (RBV)] for 48 weeks. We found that the prevalence of CKD gradually increased with age in all groups and was significantly increased in patients 60 years or older. Multivariate logistic regression analyses showed that persistent HCV infection was significantly associated with CKD [odds ratio (OR), 1.33; 95% confidence interval (CI), 1.06–1.66; P = 0.013], whereas there was no significant link between CKD and spontaneous HCV clearance (OR, 1.23; 95% CI, 0.79–1.90; P = 0.364), HBV infection (OR, 0.73; 95% CI, 0.44–1.19; P = 0.201), or HBV/HCV co-infection (OR, 1.40; 95% CI, 0.81–2.40; P = 0.234). Notably, after anti-HCV therapy, the serum creatinine concentration was significantly decreased (76.0, 75.5–79.4 μmol/L) from the pretreatment level (95.0, 93.0–97.2 μmol/L), both in patients who showed an end of treatment virological response (ETVR) and those who did not (P < 0.001). Also, in both the ETVR and non-ETVR groups, the percentages of patients with an estimated glomerular filtration rate (eGFR) ≥90 ml/min/1.73 m2 increased significantly (P < 0.001), whereas the percentages of those with an eGFR <60 ml/min/1.73 m2 significantly decreased (P < 0.001). In conclusion, persistent HCV infection was independently associated with CKD, and antiviral treatment with IFN plus RBV can improve renal function and reverse CKD in HCV-infected patients.

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
The effect of antiviral therapy (AVT) on kidney function in liver transplantation (LT) recipients has not been well described despite known association of hepatitis C virus (HCV) infection with chronic kidney disease (CKD). We compared the incidence of CKD and end-stage renal disease (ESRD) in 204 LT recipients with HCV based on treatment response to AVT. The mean estimated glomerular filtration rate (eGFR) at baseline (3 months after LT) was similar in the sustained virological response (SVR; n = 145) and non-SVR group (n = 59; 69 ± 21 versus 65 ± 33 mL/minute/1.73 m2 ; P = 0.27). In the unadjusted Cox proportional regression analysis, the presence of SVR was associated with an 88% lower risk of CKD (hazard ratio, 0.12; 95% confidence interval [CI], 0.05-0.31) and 86% lower risk of ESRD (odds ratio, 0.14; 95% CI, 0.05-0.35). Similar results were found after adjusting for propensity score and time-dependent Cox regression analyses. The estimated slopes of eGFR based on a 2-stage mixed model of eGFR were calculated. Patients with SVR had a less steep slope in eGFR (-0.60 mL/minute/1.73 m2 /year; 95% CI, -1.50 to 0.30; P = 0.190) than recipients without SVR (-2.53 mL/minute/1.73 m2 /year; 95% CI, -3.99 to -1.07; P = 0.001), and the differences in the slopes were statistically significant (P = 0.026). In conclusion, in LT recipients with chronic HCV infection, achieving SVR significantly lowers the risk of decline in renal function and progression to ESRD independent of the AVT therapy used.

Abstract
OBJECTIVES We assessed the impact of sofosbuvir-based regimens on renal function in liver transplant recipients with recurrent hepatitis C virus and the role of renal function on the efficacy and safety of these regimens. MATERIALS AND METHODS In an expanded pan-Canadian cohort, 180 liver transplant recipients were treated with sofosbuvir-based regimens for hepatitis C virus recurrence from January 2014 to May 2015. Mean age was 58 ± 6.85 years, and 50% had F3/4 fibrosis. Patients were stratified into 4 groups based on baseline estimated glomerular filtration rate (calculated by the Modification of Diet in Renal Disease formula): < 30, 30 to 45, 46 to 60, and > 60 mL/min/173 m2. The primary outcome was posttreatment changes in renal function from baseline. Secondary outcomes included sustained virologic response at 12 weeks posttreatment and anemia-related and serious adverse events. RESULTS Posttreatment renal function was improved in most patients (58%). Renal function declined in 22% of patients, which was more marked in those with estimated glomerular filtration rate < 30 mL/min/173 m2, advanced cirrhosis (P = .05), and aggressive hepatitis C virus/fibrosing cholestatic hepatitis (P < .05). High rates (80%-88%) of sustained virologic response at 12 weeks posttreatment were seen across all renal function strata. Cirrhotic patients with glomerular filtration rates < 30 mL/min/173 m2 had sustained virologic response rates at 12 weeks posttreatment comparable to the overall patient group. Rates of anemia-related adverse events and transfusion requirements increased across decreasing estimated glomerular filtration rate groups, with notably more occurrences with ribavirin-based regimens. CONCLUSIONS Sofosbuvir-based regimens improved overall renal function in liver transplant recipients, with sustained virologic response, suggesting an association of subclinical hepatitis C virus-related renal disease. Sustained virologic response rates at 12 weeks posttreatment (80%-88%) were comparable regardless of baseline renal function but lower in cirrhosis.

Abstract
We aimed to meta-analytically assess the predisposition of hepatitis C virus (HCV) infection to the occurrence and severity of chronic kidney disease (CKD). Two authors independently searched articles and abstracted information. Odds ratio (OR) or hazard ratio (HR) along with 95% confidence interval (CI) was converged separately in 12 longitudinal (1,972,044 subjects) and 15 cross-sectional (937,607 subjects) studies. Overall effect estimate was remarkably significant in longitudinal studies (HR, 95% CI, P: 1.45, 1.23-1.71, < 0.001), in contrast to that in cross-sectional studies (OR, 95% CI, P: 1.25, 0.90-1.73, 0.188), with obvious heterogeneity (I2 > 95%). HCV infection was also associated with an 1.54-fold (95% CI, P: 1.27-1.87, < 0.001) increased risk of having prevalent proteinuria. In longitudinal studies with estimated glomerular filtration rate (eGFR) < 60, < 30 and < 15 ml/min/1.73m2, the corresponding HR was 1.39 (95% CI, P: 1.14-1.69, 0.001), 1.79 (0.91-3.51, 0.091) and 2.30 (1.26-4.19, 0.007). Further grouping the longitudinal studies by median follow-up time at 5 years revealed that the effect estimate was reinforced in long-term studies (HR, 95% CI, P: 1.86, 1.19-2.89, 0.006; I2=98.1%) relative to that in short-term studies (1.21, 1.03-1.43, 0.024; 92.0%). In conclusion, our findings demonstrate the significant risk of experiencing incident CKD after HCV infection, with the lower eGFR and longer HCV exposure time entailing a greater risk.

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
AIM To determine how sustained virological response at 12 wk (SVR12) with direct acting antivirals (DAAs) for the treatment of hepatitis C virus (HCV) infection affects chronic kidney disease (CKD) progression.
METHODS A retrospective analysis was performed in patients aged ≥ 18 years treated for HCV with DAAs at the VA Greater Los Angeles Healthcare System from 2014-2016. The treatment group was compared to patients with HCV from 2011-2013 who did not undergo HCV treatment, prior to the introduction of DAAs; the control group was matched to the study group in terms of age, gender, and ethnicity. Analysis of variance and co-variance was performed to compare means between SVR12 subgroups adjusting for co-variates.
RESULTS Five hundred and twenty-three patients were evaluated. When comparing the rate of change in estimated glomerular filtration rate (eGFR) one-year after HCV treatment to one-year before treatment, patients who achieved SVR12 had a decline in GFR of 3.1 mL/min ± 0.75 mL/min per 1.73 m2 compared to a decline in eGFR of 11.0 mL/min ± 2.81 mL/min per 1.73 m2 in patients who did not achieve SVR12 (P = 0.002). There were no significant clinical differences between patients who achieved SVR12 compared to those who did not in terms of cirrhosis, treatment course, treatment experience, CKD stage prior to treatment, diuretic use or other co-morbidities. The decline in eGFR in those with untreated HCV over 2 years was 2.8 mL/min ± 1.0 mL/min per 1.73 m2, which was not significantly different from the eGFR decline noted in HCV-treated patients who achieved SVR12 (P = 0.43).
CONCLUSION Patients who achieve SVR12 have a lesser decline in renal function, but viral eradication in itself may not be associated improvement in renal disease progression.

Abstract
The treatment of hepatitis C virus (HCV) infection has progressed markedly over the last 2 decades, with a dramatic acceleration the last 3 years. The combination of two or three direct-acting antiviral drugs (DAAs) targeting viral proteins [NS3/4A protease inhibitors, NS5B nucleos(t)idic and non-nucleos(t)idic polymerase inhibitors, NS5A replication complex inhibitors], with or without ribavirin but without interferon (interferon-free regimen), for 8-24 weeks, achieved high sustained virological response (>90%), whatever fibrosis stage, genotype and subtype, baseline viral load, prior therapeutic history of the patient (naïve or experienced) and pre-existing resistance-associated variants with a fair tolerance and reduced pill burden. International guidelines recommend to ideally treat all infected patients even if a prioritization of the most severe patients (extensive fibrosis or cirrhosis, symptomatic cryoglobulinaemic vasculitis…) appears to be the best cost-effective and urgent policy. Patients with stage 4-5 chronic kidney disease (CKD) have to be considered as priority patients. Updating of the Kidney Disease: Improving Global Outcomes recommendations is due to start soon, but awaiting their availability, we present here an overview of recent developments in the field.

Abstract
BACKGROUND Treatment of chronic hepatitis C virus (HCV) infection after renal allograft transplantation has been an obstacle because of contraindications associated with IFN-based therapies. Direct-acting antiviral agents are highly efficient treatment options that do not require IFN and may not require ribavirin. Therefore, we assessed the efficacy and safety of sofosbuvir and ledipasvir in renal transplant patients with chronic HCV infection. METHODS Fifteen renal allograft recipients with therapy-naive HCV genotype (GT) 1a, 1b, or 4 were treated with the combination of sofosbuvir and ledipasvir without ribavirin for 8 or 12 weeks. Clinical data were retrospectively analyzed for viral kinetics and for renal and liver function parameters. Patients were closely monitored for trough levels of immunosuppressive agents, laboratory values, and potential adverse effects. RESULTS Ten patients (66%) exhibited a rapid virologic response within 4 weeks (HCV GT1a, n = 4; HCV GT1b, n = 6). The other 5 patients exhibited a virologic response within 8 (HCV GT 1b, n = 4) or 12 weeks (HCV GT4, n = 1). One hundred percent of patients exhibited sustained virologic response at week 12 after the end of treatment. Clinical measures of liver function improved substantially for all patients. Adverse events were scarce; renal transplant function and proteinuria remained stable. Importantly, dose adjustments for tacrolimus were necessary for maintaining sufficient trough levels. CONCLUSIONS The described regimen appears to be safe and effective for patients after renal transplant and is a promising treatment regimen for eradicating HCV in this patient population.

Abstract
BACKGROUND Empyema is a rare but important complication among patients with end-stage renal disease (ESRD). However, a nationwide, propensity-matched cohort study has never been performed. METHODS We conducted a retrospective cohort study using data from the National Health Insurance Research Database of Taiwan. The ESRD group consisted of 82 765 patients diagnosed between 2000 and 2008. The comparison group consisted of individuals without kidney disease selected at a 1:1 ratio matched by propensity score estimated with age, gender, year of diagnosis and comorbidities. The occurrence of empyema was monitored until the end of 2011. The hazard ratios (HRs) of empyema were estimated using the Cox proportional hazards model. RESULTS The incidence of empyema was 2.76-fold higher in the ESRD group than in the comparison group (23.7 vs. 8.19/10 000 person-years, P <0.001), with an adjusted HR of 3.01 [95% confidence interval (CI) = 2.67-3.39]. There was no difference of the incidence of empyema between hemodialysis (HD) and peritoneal dialysis (PD) (adjusted HR = 0.96, 95% CI = 0.75-1.23). In addition, 30-day mortality rate since empyema diagnosis was significantly higher in ESRD group than the comparison group (15.9% vs. 10.9%), with an adjusted OR of 1.69 (95% CI = 1.17-2.44). CONCLUSION The risk of empyema was significantly higher in patients with ESRD than in those without kidney disease. The occurrence of empyema was without difference in patients undergoing HD compared to those undergoing PD. The 30-day mortality rate since empyema diagnosis was also significantly higher in patients with ESRD.

Abstract
The aim of the study was to investigate the long-term association between contrast medium exposure during computed tomography (CT) and the subsequent development of end-stage renal disease (ESRD) in patients with chronic kidney disease (CKD). We conducted a population-based cohort study using Taiwan's National Health Insurance Research Database. A total of 7100 patients with nonadvanced CKD who underwent contrast medium-enhanced CT were identified and served as the study cohort. To avoid selection bias, we used the propensity score to match 7100 nonadvanced CKD patients, who underwent noncontrast medium-enhanced CT to serve as the comparison cohort. The age, sex, index year, and frequency of undergoing CTs were also matched between the study and comparison cohorts. Participants were followed until a new diagnosis of ESRD or December 31, 2011. Hazard ratios (HRs) with 95% confidence interval (95% CI) were calculated using the Cox proportional hazards regression. Contrast medium exposure was not identified as a risk factor for developing ESRD in nonadvanced CKD patients after confounders adjustment (adjusted HR = 0.91; 95% CI, 0.66-1.26; P = 0.580). We further divided the patients who underwent CTs with contrast medium use into ≤1 exposure per year on average, >1 and <2 exposure per year on average, and ≥2 exposure per year on average. After adjusting for confounders, we identified a much higher risk for developing ESRD in the 2 groups of >1 and <2 exposure per year on average and ≥2 exposure per year on average (adjusted HR = 8.13; 95% CI, 5.57-11.87 and adjusted HR = 12.08; 95% CI, 7.39-19.75, respectively) compared with the patients who underwent CTs without contrast medium use. This long-term follow-up study demonstrated that contrast medium exposure was not associated with an increased risk of ESRD development in nonadvanced CKD patients.

Abstract
BACKGROUND AND AIMS We aimed to assess the incidence and progression of chronic kidney disease (CKD) following hepatitis C virus (HCV) seroconversion. METHODS This retrospective cohort study included Veterans with a confirmed HCV seroconversion between 2001 and 2014 and Veterans with negative HCV testing over the same time period. The outcomes included development of advanced CKD (eGFR < 60 mL/min/1.73 m(2) on two separate occasions at least 90 days apart, plus a ≥ 10 mL/min/1.73 m(2) decline from baseline) and progressive CKD (decline in eGFR of ≥ 30 mL/min/1.73 m(2) from baseline). Multivariable Cox proportional hazards models were used to evaluate the association between HCV and incident advanced and progressive CKD. RESULTS The final cohort consisted of 71,528 Veterans, including 2589 with recently seroconverted HCV. Over a mean follow-up of 6 years, 36% of patients with and 31% without HCV developed advanced CKD (p < 0.001), and 35% of patients with vs. 26% without HCV developed progressive CKD (p < 0.001). After controlling for traditional risk factors, recently seroconverted HCV+ patients were significantly less likely to develop advanced CKD (HR 0.86; 95% CI 0.79, 0.92), and HCV status was not significantly associated with progressive CKD (HR 0.93; 95% CI 0.86, 1.00). Factors associated with developing advanced and progressive CKD included older age, female sex, diabetes, hypertension, development of cirrhosis, and substance abuse. CONCLUSIONS In this cohort of newly infected US Veterans, HCV infection was associated with decreased incidence of advanced and unchanged risk of progressive CKD, suggesting a larger role for traditional risk factors in the development of CKD after HCV seroconversion.

Abstract
Patients infected with HIV are at increased risk for cardiovascular disease despite successful antiretroviral therapy. Likewise, chronic hepatitis C virus (HCV) infection is associated with extrahepatic complications, including cardiovascular disease. However the risk of cardiovascular disease has not been formally examined in HIV/HCV-coinfected patients. A retrospective study was carried out to assess the influence of HCV coinfection on the risk of cardiovascular events in a large cohort of HIV-infected patients recruited since year 2004. A composite event of cardiovascular disease was used as an endpoint, including myocardial infarction, angina pectoris, stroke or death due to any of them. A total of 1136 patients (567 HIV-monoinfected, 70 HCV-monoinfected and 499 HIV/HCV-coinfected) were analysed. Mean age was 42.7 years, 79% were males, and 46% were former injection drug users. Over a mean follow-up of 79.4 ± 21 months, 3 patients died due to cardiovascular disease, whereas 29 suffered a first episode of coronary ischaemia or stroke. HIV/HCV-coinfected patients had a greater incidence of cardiovascular disease events and/or death than HIV-monoinfected individuals (4% vs 1.2%, P = 0.004) and HCV-monoinfected persons (4% vs 1.4%, P = 0.5). After adjusting for demographics, virological parameters and classical cardiovascular disease risk factors (smoking, hypertension, diabetes, high LDL cholesterol), both HIV/HCV coinfection (HR 2.91; CI 95%: 1.19-7.12; P = 0.02) and hypertension (HR 3.65; CI 95%: 1.34-9.94; P = 0.01) were independently associated with cardiovascular disease events and/or death in HIV-infected patients. Chronic hepatitis C and hypertension are independently associated with increased cardiovascular disease risk in HIV-infected patients. Therefore, treatment of chronic hepatitis C should be prioritized in HIV/HCV-coinfected patients regardless of any liver fibrosis staging.

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
BACKGROUND AND RATIONALE Chronic kidney disease and hepatitis C virus are prevalent in the general population worldwide, and controversy exists about the impact of HCV infection on the development and progression of kidney disease. DESIGN A systematic review of the published medical literature was made to assess whether positive anti-HCV serologic status plays an independent impact on the development of chronic kidney disease in the adult general population. We used a random-effects model to generate a summary estimate of the relative risk of chronic kidney disease (defined by reduced glomerular filtration rate or detectable proteinuria) with HCV across the published studies. Meta-regression and stratified analysis were also conducted. RESULTS Twenty-three studies (n = 2,842,421 patients) were eligible, and separate meta-analyses were performed according to the outcome. Pooling results of longitudinal studies (n = 9; 1,947,034 unique patients) demonstrated a relationship between positive HCV serologic status and increased incidence of chronic kidney disease, the summary estimate for adjusted hazard ratio was 1.43 (95% confidence interval 1.23; 1.63, P = 0.0001), and between-studies heterogeneity was noted (P value by Q test <0.0001). The risk of the incidence of chronic kidney disease associated with HCV, in the subset of Asian surveys, was 1.31 (95% confidence interval 1.16; 1.45) without heterogeneity (P value by Q test = 0.6). HCV positive serology was an independent risk factor for proteinuria; adjusted odds ratio, 1.508 (95% confidence intervals 1.19; 1.89, P = 0.0001) (n = 6 studies; 107,356 unique patients). CONCLUSIONS HCV infection is associated with an increased risk of developing chronic kidney disease in the adult general population.

Abstract
Epidemiological studies have reported conflicting results regarding hepatitis C virus (HCV) infection and the risk of chronic kidney disease (CKD). We systematically reviewed the literature to determine the risk of developing CKD in HCV-infected individuals compared to uninfected individuals. MEDLINE and PUBMED were searched to identify observational studies that had reported an association between HCV and CKD or end-stage renal disease (ESRD) through January 2015. Quantitative estimates [hazard ratio (HR) or odds ratio (OR)] and their 95% confidence intervals (CI) were extracted from each study. A random-effects meta-analysis was performed. Fourteen studies evaluating the risk of developing CKD/ESRD in HCV-infected individuals (n = 336,227) compared to uninfected controls (n = 2,665,631) were identified- nine cohort studies and five cross-sectional studies. The summary estimate indicated that individuals with HCV had a 23% greater risk of presenting with CKD compared to uninfected individuals (risk ratio = 1.23; 95% CI: 1.12-1.34). Results were similar by study type, for cohorts (HR = 1.26; 95% CI: 1.12-1.40) and cross-sectional studies (OR = 1.21; 95% CI: 1.09-1.32). Country-stratified analysis demonstrated a significantly increased risk between HCV and CKD in the Taiwanese subgroup (risk ratio = 1.28; 95% CI: 1.12-1.34) and the US subgroup (risk ratio = 1.17; 95% CI: 1.01-1.32). Egger regression revealed no evidence of publication bias. HCV infection is associated with a greater risk of developing and progression of CKD compared to uninfected controls.

Abstract
The long-term survival of end-stage renal disease (ESRD) patients with hepatitis C virus (HCV) infection who received interferon treatment has not been extensively evaluated.The HCV cohort was the ESRD patients with de novo HCV infection from 2004 to 2011; they were classified into treated and untreated groups according to interferon therapy records. Patients aged <20 years and those with a history of hepatitis B, kidney transplantation, or cancer were excluded. The control cohort included ESRD patients without HCV infection matched 4:1 to the HCV cohort by age, sex, and year of ESRD registration. We followed up all study participants until kidney transplantation, death, or the end of 2011, whichever came first. We assessed risk of all-cause mortality by using the multivariate Cox proportional hazard model with time-dependent covariate.In the HCV cohort, 134 patients (6.01%) received interferon treatment. Compared with the uninfected control cohort, the treated group had a lower risk of death (hazard ratio 0.47, 95% confidence interval [CI] 0.22-0.99). The untreated group had a 2.62-fold higher risk (95% CI 1.24-5.55) of death compared with the treated group. For the HCV cohort without cirrhosis or hepatoma, the risk of death in the treated group was further markedly reduced (hazard ratio 0.17, 95% CI 0.04-0.68) compared with that in the control cohort.For ESRD patients with HCV infection, receiving interferon treatment is associated with a survival advantage. Such an advantage is more prominent in HCV patients without cirrhosis or hepatoma.

Abstract
AIM Despite several studies, the extent to which hepatitis C virus (HCV) infection is associated with chronic kidney disease (CKD) remains controversial. Thus, we examined the relationship between HCV and CKD using the continuous National Health and Nutrition Examination Survey (1999-2012). METHODS Specimens positive for anti-HCV antibodies were retested and confirmed with recombinant immunoblot assay (RIBA). Proteinuria was defined as urine albumin creatinine ratio > 30 mg/g. CKD was defined as estimated glomerular filtration rate (GFR) < 60 mL/min/1.73 m(2) . We used linear and logistic regression models to examine the association between HCV and outcomes with and without adjustment for age, sex, race, hypertension, diabetes mellitus, and body mass index and accounting for the complex survey design. RESULTS Of the 33,729 eligible participants, HCV infection was present in 659 (1.73%). In unadjusted and adjusted analyses, HCV was associated with proteinuria (OR = 1.40, p = 0.01 and OR = 1.50, p = 0.02, respectively). In both unadjusted and adjusted analyses, individuals with HCV had significantly higher GFR than individuals without (1.4 mL/min, p = 0.04 and 2.7 mL/min, p < 0.001, respectively). We did not find an association of HCV with CKD in adjusted or unadjusted analyses. CONCLUSION HCV infection is associated with proteinuria and high GFR but not with CKD. The biological mechanism of the observed association needs further study.

Abstract
Inflammation, which initiates endothelial dysfunction, vascular atherosclerosis, and oxidative stress, may negatively influence renal function and accelerate the development of end-stage renal disease (ESRD). The role of chronic osteomyelitis (COM), a chronic inflammatory disease, in the development of ESRD has not been investigated. This study explored whether patients with COM have a higher risk of ESRD than that of patients without COM.Taiwan National Health Insurance claims from 1997 to 2010 were used to identify 24,267 newly diagnosed patients with COM and 97,068 age- and sex-matched non-COM controls for comparison. The risks of ESRD among COM patients, with adjustment for comorbidities, namely, hypertension, diabetes, coronary artery disease, congestive heart failure, and hyperlipidemia, were assessed until the end of 2010.ESRD risk was 2.01-fold higher (95% confidence interval [CI]: 1.81-2.25) in the COM cohort than in the non-COM cohort. Regarding the joint effect of COM with comorbidity, the ESRD risk was 1.57-fold higher (95% CI: 1.23-2.00) for the COM cohort without comorbidities and increased to 2.25 (95% CI: 1.97-2.57) for the COM cohort with at least 1 comorbidity. Age-specific analysis revealed that the adjusted ESRD risk for the COM cohort increased as age decreased, with the highest hazard ratio being 17.8 (95% CI: 5.18-61.4) for patients aged 20-34 years.This was the first study to report that COM is associated with an increased risk of ESRD, particularly among patients with comorbidities and younger patients.

Abstract
UNLABELLED An estimated 4 million Americans have been exposed to the hepatitis C virus (HCV). The risks of incident and progressive chronic kidney disease and of mortality in patients with normal kidney function infected with HCV are unclear. In a nationally representative cohort of 100,518 HCV(+) and 920,531 HCV(-) US veterans with normal baseline estimated glomerular filtration rate (eGFR), we examined the association of HCV infection with (1) all-cause mortality, (2) incidence of decreased kidney function (defined as eGFR <60 mL/min/1.73 m(2) and 25% decrease in eGFR), (3) end-stage renal disease, and (4) rate of kidney function decline. Associations were examined in naive and adjusted Cox models (for time-to-event analyses) and logistic regression models (for slopes), with sequential adjustments for important confounders. Propensity-matched cohort analysis was used in sensitivity analyses. The patients' age was 54.5 ± 13.1 (mean ± standard deviation) years, 22% were black, 92% were male, and the baseline eGFR was 88 ± 16 mL/min/1.73 m(2) . In multivariable adjusted models HCV infection was associated with a 2.2-fold higher mortality (fully adjusted hazard ratio = 2.17, 95% confidence interval [CI] 2.13-2.21), a 15% higher incidence of decreased kidney function (adjusted hazard ratio = 1.15, 95% CI 1.12-1.17), a 22% higher risk of steeper slopes of eGFR (adjusted odds ratio = 1.22, 95% CI 1.19-1.26), and a 98% higher hazard of end-stage renal disease (adjusted hazard ratio = 1.98, 95% CI 1.81-2.16). Quantitatively similar results were found in propensity-matched cohort analyses. CONCLUSIONS Infection with HCV is associated with higher mortality risk, incidence of decreased kidney function, and progressive loss of kidney function; randomized controlled trials are warranted to determine whether treatment of HCV infection can prevent the development and progression of chronic kidney disease and improve patient outcomes.

Abstract
Background Recent reports suggest that telaprevir, a protease inhibitor used to treat hepatitis C infection, is associated with decline in kidney function during therapy, particularly in patients with baseline renal impairment. Methods Patients treated with telaprevir in a single healthcare network were retrospectively reviewed. Kidney function was determined at baseline, during therapy, and twelve weeks and twelve months after telaprevir discontinuation. Significant creatinine rise during therapy was defined as an increase in serum creatinine ≥ 0.3mg/dL from baseline during treatment with telaprevir. Results Between July 2011 to January 2013,seventy-eight patients began treatment. The majority completed the prescribed twelve weeks of telaprevir therapy; 32% discontinued due to side effects. The average rise in serum creatinine during therapy was 0.22mg/dL (standard deviation 0.22mg/dL). Thirty-one percent experienced a significant creatinine rise during therapy. Decline in estimated glomerular filtration rate (eGFR) was lower in those with baseline eGFR < 90 mL/min/1.73m2 compared to the group with baseline eGFR ≥ 90 mL/min/1.73m2 (12 vs. 18 mL/min/1.73m2, P = 0.047). Serum creatinine fully normalized by twelve weeks after cessation of telaprevir in 83% of patients, however experiencing a significant creatinine rise during telaprevir use was associated with a 6.6mL/min/1.73m2 decrease in estimated glomerular filtration rate at twelve months in an adjusted model. Conclusions Decline in kidney function during therapy with telaprevir is common and is not associated with baseline eGFR < 90mL/min/1.73m2 as previously reported.

Abstract
OBJECTIVE To elucidate the association between antiviral therapy and extrahepatic outcomes in individuals infected with HCV. METHODS This nationwide cohort study screened 293,480 Taiwanese residents with HCV infection and excluded those with substantial comorbidity. A total of 12,384 eligible patients who had received pegylated interferon plus ribavirin between 1 October 2003 and 31 December 2010 were enrolled in the treated cohort; they were matched 1 : 2 with 24,768 untreated controls in the propensity score and post-diagnosis treatment-free period. The incidences of end-stage renal disease (ESRD), acute coronary syndrome (ACS), ischaemic stroke and catastrophic autoimmune diseases were calculated after adjustment for competing mortality. RESULTS The treated and untreated cohorts were followed up for a mean (±SD) duration of 3.3 (±2.5) and 3.2 (±2.4) years, respectively, until 31 December 2011. The calculated 8-year cumulative incidences of ESRD, ACS, ischaemic stroke and autoimmune catastrophes between treated and untreated patients were 0.15% vs. 1.32% (p<0.001), 2.21% vs. 2.96% (p=0.027), 1.31% vs. 1.76% (p=0.001) and 0.57% vs. 0.49% (p=0.816), respectively. Multivariate-adjusted Cox regression revealed that antiviral treatment was associated with lower risks of ESRD (HR 0.15; 95% CI 0.07 to 0.31; p<0.001), ACS (HR 0.77; 95% CI 0.62 to 0.97; p=0.026) and ischaemic stroke (HR 0.62; 95% CI 0.46 to 0.83; p=0.001), but unrelated to autoimmune catastrophes. These favourable associations were invalid in incompletely treated patients with duration <16 weeks. CONCLUSIONS Antiviral treatment for HCV is associated with improved renal and circulatory outcomes, but unrelated to catastrophic autoimmune diseases.

Abstract
BACKGROUND & AIMS The relationship between hepatitis C virus (HCV) infection and peripheral arterial disease (PAD) development remains unclear. METHODS Health insurance claims data were used to construct a cohort of HCV-infected patients diagnosed during the period 1998-2011. Patients younger than 20 years and those with history of hepatitis B or PAD were excluded. We selected 7641 HCV-infected patients and 30564 matched controls. The adjusted risk of developing PAD was analyzed using a multivariate Cox hazard model. RESULTS The results show that the excess risk of PAD development in HCV-infected patients is 1.43-fold higher (95% CI=1.23-1.67) compared with non-HCV patients. The adjusted risk of PAD development increases with age; compared with the 20-34 year-old patients, the risk is 3.96-fold higher in HCV-infected patients aged 35-49 years, and 11.7-fold higher in those aged 65 years and above. CKD/ESRD has the highest risk for PAD (HR=1.80, 95% CI=1.29-2.53). HCV-infected patients with four comorbidities exhibit a substantially higher risk of developing PAD (HR=9.25, 95% CI=6.35-13.5). Excess risk of developing PAD is observed from the first year of follow-up till the third year. CONCLUSION HCV-infected patients have an independently higher risk of developing PAD. HCV-infected patients with comorbidity have increased risk of developing PAD.

Abstract
The 2011 report of the World Health Organization General Assembly on noncommunicable diseases identified chronic kidney disease as a worldwide health issue posing a heavy economic burden. Hepatitis C virus infection, which is responsible for over 1 million deaths resulting from cirrhosis and liver cancer, is linked to chronic kidney disease in several ways; some forms of renal disease are precipitated by hepatitis C and patients with end-stage chronic renal disease are at increased risk for acquiring HCV. The aim of this review is to update the evidence on the relationship between hepatitis C infection and chronic kidney disease. Information has been accumulated in the last decade indicating that HCV plays an adverse effect on the incidence and progression of chronic kidney disease; a novel meta-analysis of observational studies (seven longitudinal studies; 890,560 unique individuals) found a relationship between hepatitis C seropositivity and incidence of reduced estimated glomerular filtration rate (adjusted relative risk, 1.70; 95% CI, 1.20; 2.39; P=0.002) in the adult general population. In addition to conventional risk factors, hepatitis C may be an additional factor for the development of chronic kidney disease, and an atheromasic activity of hepatitis C virus has been mentioned. The link between hepatitis C and atherosclerosis could also explain the excess risk of cardiovascular mortality that has been observed among hepatitis C virus seropositive patients undergoing maintenance dialysis. A number of biologically plausible mechanisms related to hepatitis C virus have been hypothesized to contribute to atherosclerosis. Implementation of effective treatment intervention towards hepatitis C is required to decrease the healthcare burden of hepatitis C and to prevent the progression of chronic renal disease.

Abstract
Background Chronic kidney disease (CKD) and hepatitis C virus (HCV) infection are closely linked and both increase patient mortality. The association of HCV and risk of developing end-stage renal disease (ESRD) has not been analyzed with competing risk model. Method We enrolled a prospective cohort of 4,185 patients (mean age, 62 years; 41% female) registered in the CKD integrated care program at two affiliated hospitals of Kaohsiung Medical University in Taiwan between November 11, 2002 and May 31, 2009. With competing risk model, we analyzed the association of HCV infection, defined by seropositive of anti-HCV antibody, and hepatitis B virus (HBV) infection, defined by seropositive of HBV surface antigen, with the risk of entering ESRD. Results The prevalence of HCV infection was 7.6% and it increased with the CKD stages (trend test, P<0.001), while the prevalence of HBV infection was 7.4% and no specific trend among CKD stages (tend test, P = 0.1). During the 9,101 person-year follow-up period, there were 446 death and 1,205 patients entering ESRD. After adjusting death as the competing risk, the estimated 5-year cumulative incidence rate of ESRD among patients with and without HCV infection were 52.6% and 38.4%, respectively (modified log-rank, P<0.001). Multivariable analysis showed that HCV infection, but not HBV infection, had higher risk of developing ESRD compared with cases without infection (HCV, HR: 1.32, 95% CI: 1.07–1.62; HBV, HR: 1.10, 95% CI: 0.89–1.35). Subgroup analyses showed consistent results. Conclusions With death-adjusted competing risk analysis, HCV infection is associated with an increased risk of developing ESRD in CKD cohort.

Abstract
Background Hepatitis C virus (HCV) infection and chronic kidney disease (CKD) have high prevalences in Taiwan and worldwide, but the role of HCV infection in causing CKD remains uncertain. This cohort study aimed to explore this association. Methods This nationwide cohort study examined the association of HCV with CKD by analysis of sampled claims data from Taiwan National Health Insurance Research Database from 1998 to 2004. ICD-9 diagnosis codes were used to identify diseases. We extracted data of 3182 subjects who had newly identified HCV infection and no traditional CKD risk factors and data of randomly selected 12728 matched HCV-uninfected control subjects. Each subject was tracked for 6 years from the index date to identify incident CKD cases. Cox proportional hazard regression was used to determine the risk of CKD in the HCV-infected and control groups. Results The mean follow-up durations were 5.88 years and 5.92 years for the HCV-infected and control groups, respectively. Among the sample of 15910 subjects, 251 subjects (1.6%) developed CKD during the 6-year follow-up period, 64 subjects (2.0%) from the HCV-infected group and 187 subjects (1.5%) from the control group. The incidence rate of CKD was significantly higher in the HCV-infected group than in the control group (3.42 vs. 2.48 per 1000 person-years, p = 0.02). Multivariate analysis indicated that the HCV-infected group had significantly greater risk for CKD (adjusted hazard ratio: 1.75, 95% CI: 1.25-2.43, p = 0.0009). This relationship also held for a comparison of HCV-infected and HCV-uninfected subjects who were younger than 70 years and had none of traditional CKD risk factors. Conclusions HCV infection is associated with increased risk for CKD beyond the well-known traditional CKD risk factors. HCV patients should be informed of their increased risk for development of CKD and should be more closely monitored.
