[PMID: 37974105 PMCID: PMC10652521 DOI: 10.1186/s12879-023-08726-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Accepted: 10/18/2023] [Indexed: 11/19/2023] Open
Abstract
BACKGROUND Healthcare utilization is typically adversely affected when the treatment is expensive and requires multiple visits. We examined the determinants of healthcare-seeking for Hepatitis C virus (HCV) infection which is asymptomatic, chronic, and requires costly treatment in an urban tertiary care referral hospital in Vietnam. METHODS We conducted a secondary analysis of hospital data for patients attending the Hospital for Tropical Diseases in Ho Chi Minh City, Vietnam between 2017 and 2020 specifically for HCV infection treatment. Poisson regression was used to determine the effect of personal factors (age, sex, comorbidities) and structural factors (health insurance, proximity to the facility, seasonality, year of visit) on the number of hospital visits. RESULTS From 2017 to 2020 a total of 22,052 eligible patients sought treatment in the hospital. Among the patients, 50.4% were males and 58.7% were > 50 years of age. The mean number of visits per person was 2.17. In the multivariate analysis compared to 2017, the number of hospital visits increased by 4% in 2018 and then significantly decreased in 2019 and 2020. Visit numbers were significantly lower (6%) among South East region residents compared to those from Central Highlands and for those who lived further away from the hospital. The visit numbers were significantly higher among older age groups (5-11%), those with health insurance (6%), and those with comorbidities (5%) compared to others. Although the number of hospital visits by females was higher (7%) than males in 2017, it significantly decreased in subsequent years. CONCLUSIONS Our study indicated that there are both structural and individual factors affecting the number of visits for HCV treatment. To meet the global strategy for elimination of HCV, Vietnam Government needs to address the structural and personal barriers to healthcare seeking, with a special focus on women.

Pan-genotypic direct-acting antivirals for patients with hepatitis C virus infection and chronic kidney disease stage 4 or 5. Hepatol Int 2022; 16:1001-1019. [PMID: 35876967 PMCID: PMC9309604 DOI: 10.1007/s12072-022-10390-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Accepted: 07/03/2022] [Indexed: 12/17/2022]
Abstract
Hepatitis C virus (HCV) infection is a major health problem with significant clinical and economic burdens in patients with chronic kidney disease (CKD) stage 4 or 5. Current guidelines recommend pan-genotypic direct-acting antivirals (DAAs) to be the first-line treatment of choice for HCV. This review summarizes the updated knowledge regarding the epidemiology, natural history, public health perspectives of HCV in patients with CKD stage 4 or 5, including those on maintenance dialysis, and the performance of pan-genotypic DAAs in these patients. The prevalence and incidence of HCV are much higher in patients with CKD stage 4 or 5 than in the general population. The prognosis is compromised if HCV patients are left untreated regardless of kidney transplantation (KT). Following treatment-induced HCV eradication, patient can improve the health-related outcomes by maintaining a long-term aviremic state. The sustained virologic response (SVR12) rates and safety profiles of pan-genotypic DAAs against HCV are excellent irrespective of KT. No dose adjustment of pan-genotypic DAAs is required across CKD stages. Assessing drug–drug interactions (DDIs) before HCV treatment is vital to secure on-treatment safety. The use of prophylactic or preemptive pan-genotypic DAAs in HCV-negative recipients who receive HCV-positive kidneys has shown promise in shortening KT waiting time, achieving excellent on-treatment efficacy and safety, and maintaining post-KT patient and graft survival. HCV elimination is highly feasible through multifaceted interventions, including mass screening, treatment scale-up, universal precautions, and post-SVR12 reinfection surveillance.

The Impact of Hepatitis C Virus, Metabolic Disturbance, and Unhealthy Behavior on Chronic Kidney Disease: A Secondary Cross-Sectional Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19063558. [PMID: 35329244 PMCID: PMC8952695 DOI: 10.3390/ijerph19063558] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Revised: 03/09/2022] [Accepted: 03/11/2022] [Indexed: 11/17/2022]
Abstract
BACKGROUND Hepatitis C virus (HCV) infection is associated with a higher risk of chronic kidney disease (CKD). This study investigates the relationship among HCV, CKD, and understudied confounders, such as unhealthy behaviors and metabolic disturbances. METHODS This cross-sectional study was conducted as part of a community health promotion program in an HCV endemic area of Taiwan from June to December 2019. Multivariable logistic regression analyses adjusted for demographic and clinical characteristics were performed to investigate the association between CKD and HCV seropositivity. RESULTS Of 2387 participants who underwent health check-ups, the mean age was 64.1 years old; females predominated (63.2%), and 306 (12.8%) subjects were seropositive for HCV. CKD, defined as a lower estimated glomerular filtration rate (eGFR) was associated with unhealthy dietary habits, metabolic syndrome, and HCV. Less frequent exercise, higher waist circumference (WC) and HbA1c all affected risk of CKD; HCV increased risk of CKD by 44% compared to non-HCV (OR 1.44, 95% confidence interval (CI) 1.05-1.98) in the multivariable analysis. In the HCV group, lower eGFR was also significantly associated with the severity of metabolic syndrome (MetS) (median eGFR was 86.4, 77.1, and 64.5 mL/min/1.73 m2 for individuals with three and five MetS components, respectively). CONCLUSIONS Beyond metabolic disturbance and irregular exercise, HCV seropositivity is independently associated with CKD in a community survey. Healthy lifestyle promotion might protect against renal function decline in HCV; however, the mechanisms underlying the association need further large-scale investigation.

Abstract
ABSTRACT Viral infections, including hepatitis C, can cause secondary glomerular nephropathies. Studies suggest that hepatitis C virus infection (HCV+) is a risk factor for chronic kidney disease (CKD) but evidence of this relationship is lacking among Hispanics/Latinos. We examined the association between HCV+ and incident CKD in a prospective cohort of Hispanics/Latinos enrolled in the Hispanic Community Health Study/Study of Latinos. HCV+ was defined by detectable HCV antibodies with additional confirmation through HCV RNA or recombinant immunoblot assay testing. Incident CKD was defined by an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 or sex-specific threshold for albuminuria measured during follow-up. We used Poisson regression to estimate incidence rate ratios (IRR) of CKD and changes in eGFR- or albuminuria-based risk stages, separately. We used linear regression to estimate associations with continuous, annualized changes in eGFR and albuminuria.Over a follow-up period of 5.9 years, 712 incident CKD events occurred among 10,430 participants. After adjustment for demographic characteristics and comorbidities, HCV+ was not associated with incident CKD, defined by eGFR and albuminuria thresholds (IRR 1.29, 95% Confidence Interval 0.61, 2.73). HCV+ was significantly associated with higher eGFR risk stages (IRR 2.39, 95% CI 1.47, 3.61) with most participants transitioning from stage G1 to G2. HCV+ was associated with a continuous, annualized eGFR decline of -0.69 mL/min/m2/year (95% CI -1.23, -0.16). This large, cohort study did not find evidence of a strong association between HCV+ and new-onset CKD among Hispanics/Latinos. HCV infection may not be associated with risk of CKD among Hispanics/Latinos, although treatment with direct-acting antivirals is recommended for all HCV+ individuals, including those with established CKD or end-stage kidney disease.

Abstract
The lack of knowledge of advance care planning and training of communication skills among nurses in Taiwan is one of the main reasons for the low rate of advance directive signing. However, there is no specific and effective solution to this problem. The purposes of this study were (1) to develop and pilot testing of an advance care planning simulation-based communication training program and (2) to evaluate the feasibility and acceptability of the program. This study was conducted in three phases. Phase 1: Developing an advance care planning simulation-based communication training program; Phase 2: Conducting a pilot test; Phase 3: Evaluating the feasibility and acceptability of the program. Twelve convenient participants from a medical center in central Taiwan were selected. The participants believed that team-based learning was beneficial for several reasons. First, it helped to clarify the participants’ understanding of advance care planning and improve their communication skills. Second, role-playing, as one of the components, was helpful for discovering their own shortcomings in communication skills while debriefing enabled them to identify their blind spots in the communication process. Finally, the reflection log documented their weekly performance so they were able to reflect upon their weekly performance, improve their performance, and become more confident. All twelve participants signed the consent form and completed the whole training program. The participants were satisfied with the program, affirming that the timing and content of the program were appropriate and that the expected learning outcomes could be achieved. According to participant feedback, the program was beneficial in improving their knowledge of advance care planning and confidence in communication. Thus, it is feasible and acceptable to introduce communication of advance care planning programs into the staff training protocols of healthcare organizations. Clinical trial registration:NCT04312295.

Clinical outcomes of hepatitis C virus elimination using glecaprevir and pibrentasvir in hemodialysis patients: A multicenter study. Hepatol Res 2020; 50:557-564. [PMID: 31883211 DOI: 10.1111/hepr.13482] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/21/2019] [Revised: 12/24/2019] [Accepted: 12/26/2019] [Indexed: 12/22/2022]
Abstract
AIM The incidence of hepatitis C virus (HCV) infection is much higher in hemodialysis patients than that in healthy individuals. The prognosis of hemodialysis patients with HCV infection is poorer than that without HCV infection. Therefore, antiviral intervention is pivotal for HCV infection in hemodialysis patients. Recent evaluations of the pangenotypic regimen of glecaprevir/pibrentasvir show that it is highly effective and safe for HCV-infected hemodialysis patients. However, a few reports showed that the effect of HCV elimination by glecaprevir/pibrentasvir improved liver dysfunction or anemia. The aim of the present study was to determine clinical outcomes after HCV elimination using the glecaprevir/pibrentasvir regimen in HCV-infected hemodialysis patients. METHODS This study was a retrospective, six-center study conducted in Japan, in which 24 hemodialysis patients with HCV genotype 1-2 treated with glecaprevir/pibrentasvir were recruited. Blood examinations were performed at end of treatment (EOT), and at 3, 6, and 12 months post-treatment during the 12-month follow-up period. RESULTS The overall sustained virologic response rate was 100% (24/24). During the DAA treatment period, adverse events were observed in 20.8% of patients (5/24), and pruritus was the most frequently observed in 12.5% (3/24). Interestingly, we observed an improved control of anemia after EOT with a significant increase in hemoglobin levels. In addition, total bilirubin was diminished, and platelet counts and albumin, total cholesterol, and alpha-fetoprotein levels remained unchanged after EOT in hemodialysis patients. Furthermore, erythropoietin concentration was not increased after EOT. CONCLUSIONS HCV elimination using glecaprevir/pibrentasvir treatment might be a major breakthrough for the control of anemia in hemodialysis patients.

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
BACKGROUND Although the prevalence of extrahepatic manifestations of chronic hepatitis C virus (HCV) infection has been reported from Western countries, their prevalence in East Asian countries is not well known. AIM To perform a systematic review to quantify the prevalence of selected extrahepatic manifestations of HCV among patients from East Asia. METHODS Medline, CINAHL, EMBASE, Cochrane and country-specific databases were reviewed according to standard guidelines for meta-analyses. Only articles with patients from East Asian countries were included. RESULTS After review, 34 articles were selected (Japan = 9; China = 5, Korea = 3, Taiwan = 16, multiple countries = 1) with 646 228 subjects, 66 436 with HCV. Mean age for HCV-infected patients was 56 years (range 41-72 years), 50% were male (range 26%-73%). The pooled prevalence of type 2 diabetes in East Asian HCV patients was 19.0% (95% confidence interval 15.6%-22.9%) (n = 19 studies) with an increased risk when compared to non-HCV: odds ratio (OR) 1.58 (1.28-1.94). The prevalence of chronic kidney disease in HCV was 9.2% (5.0%-16.2%) (n = 7 studies), also with a significantly increased risk: OR=1.98 (1.41-2.77). Pooled prevalence of cardiovascular disease in HCV was 8.6% (3.5%-19.9%) (n = 6 studies), also with an increased risk: OR = 1.55 (1.21-1.98). The prevalence of lichen planus in HCV was 8.9% (3.6%-20.6%) (n = 6 studies) while the prevalence of rheumatoid arthritis was 4.5% (0.6%-25.7%) (n = 4 studies). CONCLUSIONS These data show increased risk of developing extrahepatic manifestations in East Asian patients with HCV. Both hepatic and extrahepatic manifestations of the infection should be used to accurately determine the total burden of the disease in the region.

Abstract
Aim of the study To determine the seroprevalence of hepatitis C virus (HCV) in outpatients with chronic kidney disease (CKD) attending a nephrology clinic. Material and methods Prospective observational study on consecutive outpatients attending a nephrology clinic. Inclusion criteria were age > 18 years, CKD, informed consent. There were no exclusion criterias. Recorded variables were age, gender, CKD grade and etiology, anti-HCV antibodies (Ab). Patients with positive HCV Abs were tracked for HCV RNA detection. Study interval was from November 2015 to March 2016. The study has been approved by the Ethic committee of F.D. Roosevelt University Hospital. Funded by Restricted Grant of AbbVie Slovakia. Results One hundred and thirty-four patients were enrolled, with median age 70 years (19.7-91), 52% women. CKD grades: G1/2 – 52 patients (39%), G3a – 34 patients (25%), G3b – 32 patients (24%), G4 – 8 patients (6%), G5 – 8 patients (6%); CKD etiology: tubulointerstitial nephritis (TIN) – 53 patients (40%), nephrosclerosis (NS) – 30 patients (22%), diabetic nephropathy (DN) – 23 patients (17%), glomerulonephritis (GN) – 23 patients (17%), others – 5 patients (4%). Anti-HCV antibodies were detected in 8 patients (6%). There were no significant differences in CKD grades between HCV+ and HCV– patients; Heymann nephritis and GN were significantly more frequent in HCV– patients, as was male gender. Of 8 HCV Ab positive patients, 5 were available for HCV RNA testing (2 died after completion of the study, 1 was lost to follow-up); of them, 1 patient tested positive. Conclusions Prevalence of anti-HCV antibodies in CKD patients was 6%, which is 4 times higher than in the general population of Slovakia; HCV RNA was detected in 1 patient (12.5%) of anti-HCV positive patients. Based on this result, multicentric, a larger-scale study is considered to be warranted.

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
BACKGROUND AND OBJECTIVES Studies evaluating the role of hepatitis C viral (HCV) infection on the progression of CKD are few and conflicting. Therefore, we evaluated the association of untreated HCV on kidney function decline in patients with stage 3-5 CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This retrospective cohort study included members of Kaiser Permanente Southern California and Kaiser Permanente Mid-Atlantic States aged ≥18 years, with incident HCV and CKD diagnoses from January 1, 2004 to December 31, 2014. We used generalized estimating equations to compare the rate of change in eGFR between those with HCV and CKD versus CKD alone, adjusting for covariates. Cox proportional hazards models compared the risk of 25% decrease in eGFR and ESKD (defined as progression to eGFR<15 ml/min per 1.73 m2 on two or more occasions, at least 90 days apart) in those with HCV and CKD versus CKD alone, adjusting for covariates. RESULTS We identified 151,974 patients with CKD only and 1603 patients with HCV and CKD who met the study criteria. The adjusted annual decline of eGFR among patients with HCV and CKD was greater by 0.58 (95% confidence interval [95% CI], 0.31 to 0.84) ml/min per 1.73 m2, compared with that in the CKD-only population (HCV and CKD, -1.61; 95% CI, -1.87 to -1.35 ml/min; CKD only, -1.04; 95% CI, -1.06 to -1.01 ml/min). Adjusted for covariates, the hazard for a 25% decline in eGFR and for ESKD were 1.87 (95% CI, 1.75 to 2.00) and 1.93 (95% CI, 1.64 to 2.27) times higher among those with HCV and CKD, respectively, compared with those with CKD only. CONCLUSIONS Untreated HCV infection was associated with greater kidney function decline in patients with stage 3-5 CKD.

Elimination of hepatitis C virus infection from a hemodialysis unit and impact of treatment on the control of anemia. GASTROENTEROLOGIA Y HEPATOLOGIA 2018; 42:164-170. [PMID: 30293914 DOI: 10.1016/j.gastrohep.2018.07.015] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/07/2018] [Revised: 07/23/2018] [Accepted: 07/29/2018] [Indexed: 12/13/2022]
Abstract
INTRODUCTION In the interferon era, the treatment of hepatitis C virus (HCV) infection in patients on haemodialysis (HD) was limited due to the significant number of treatment-related adverse events (AEs). Direct-acting antivirals (DAAs) have demonstrated their efficacy and safety in the treatment of HCV in patients with advanced chronic kidney disease on haemodialysis. The objective of the study was to evaluate the success in eliminating HCV infection from our dialysis unit using DAAs, and to assess the impact of HCV elimination on clinical and analytical outcomes. PATIENTS AND METHODS This is a prospective, interventional, single-center study at Hospital Clínic de Barcelona. All HCV-RNA positive patients who received antiviral therapy with DAAs within a 3-year period (2014-2017) were analyzed (n=20). Data on virologic response, adverse events, and biochemical and hematological parameters during and after DAA therapy were analyzed. RESULTS All patients achieved sustained virologic response (SVR) and only 40% of patients presented with mild AEs. None of the patients presented with HCV reinfection after a 1-year follow-up period, and thus HCV was eliminated from our HD unit. SVR was associated with a significant increase in hemoglobin and hematocrit, and a tendency toward the need for lower doses of iron supplementation with no changes in darbepoetin dose. CONCLUSION HCV infection can be safely eliminated from HD units with the use of DAAs, preventing new infections in patients and healthcare staff. In the short term, the achievement of SVR is associated with an improvement in the control of anemia.

Abstract
The effectiveness and safety of direct-acting antiviral agents (DAAs) in hepatitis C virus (HCV) patients with renal insufficiency remain controversial. Therefore, this network meta-analysis aims to assess effectiveness and safety of DAAs in populations with different renal function. The pooled data were obtained from Cochrane Library, EMBASE, PubMed, and Web of Science. Thirteen studies recruited 6884 patients with hepatitis C infection and reported their outcomes in relation to different levels of renal function after treatment with DAAs. The results showed no difference in the virologic responses among patients with different renal function. Regarding safety, whereas in patients without chronic kidney disease (CKD) or with early CKD DAAs were associated with a risk ratio (RR) of 0.14 (95% confidence interval (CI), 0.04 to 0.43) for renal disorder, increased risk of renal function deterioration was found in advanced-CKD patients, though this effect may be related to the natural course of advanced CKD. Similarly, patients without CKD or with early CKD showed a lower risk of anemia (RR, 0.34; 95% CI, 0.20 to 0.57) and discontinuation (RR, 0.41; 95% CI, 0.39 to 0.56) than patients with advanced CKD. The efficacy of DAAs for HCV treatment was comparable in patients with advanced CKD and in those with early CKD or without CKD. However, the safety of DAAs should be verified in future studies.

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 Hepatitis C virus (HCV) is a risk factor for chronic kidney disease (CKD) and end-stage renal disease (ESRD). Direct-acting antiviral agents (DAAs) have improved HCV management in CKD patients, however real-world clinical practice data are limited. OBJECTIVE This study examined the prevalence of CKD among HCV patients receiving oral DAAs in a real-world setting. Comorbidities, early discontinuation rates, and healthcare costs were compared between patients with and without CKD. METHODS Patients with HCV who were treated with oral DAAs between November 2013 and June 2015, and who were enrolled in a US health plan, were identified. Early discontinuation was calculated based on observed versus expected treatment duration, and expected treatment duration was based on genotype, initial treatment regimen, baseline cirrhosis, and prior treatments. Healthcare costs were calculated during the baseline, treatment, and post-treatment periods. RESULTS This study included 3438 patients receiving oral DAAs, of whom 6.9% had a CKD diagnosis. CKD patients were more often male (70.8 vs. 62.9%, p = 0.02) and older (mean age 62.0 vs. 58.8 years, p < 0.001) than non-CKD patients, and had a higher prevalence of most comorbidities. Among early discontinuers, CKD patients were more likely to experience anemia (19.4 vs. 7.7%, p = 0.028). CONCLUSIONS Few patients with CKD receive DAA treatment for HCV infections. HCV patients with CKD had significantly more comorbidities and higher baseline healthcare costs than patients without CKD. Compared with non-CKD patients, CKD patients were equally likely to discontinue DAA treatment early but had higher rates of anemia. This study highlights the need for more renal-friendly HCV therapies.

Abstract
All-oral, direct-acting antivirals (DAAs) have significantly improved the efficacy and safety of chronic hepatitis C (CHC) treatment but their effectiveness and safety among patients with chronic kidney disease (CKD) remains poorly understood. Our aim was to assess the efficacy and safety of DAAs for treatment of CKD patients. The National Library of Medicine through PubMed was searched for studies evaluating the efficacy of DAAs for the treatment of patients with CKD stages 4 or 5, as defined by the Kidney Disease Outcomes Quality Initiative guidelines [i.e. glomerular filtration rate (GFR) 15-29 ml/min per 1.73 m2 and GFR <15 ml/min per 1.73 m2, respectively, or hemodialysis or peritoneal dialysis]. Randomized clinical trials (RCTs) and relevant cohort studies were included if they were published in English and included sustained viral response after 12 weeks (SVR12) as a primary or secondary endpoint. After applying inclusion and exclusion criteria, eight studies (one RCT and seven cohort studies) following 350 patients were selected. For patients with CKD stage 4 or 5, ± hemodialysis, the overwhelming majority of DAA regimens were well-tolerated and resulted in SVR12 rates of 90-100%. Most studies were small, with the exception of one RCT evaluating elbasvir and grazoprevir. Overall, treatment of CHC in patients with CKD is highly effective with SVR12 rates similar to those seen in patients without CKD and with acceptable adverse event profiles. In patients with hepatitis C virus (HCV) genotype (GT) 1a, 1b or 4 and Stage 4 or 5 CKD, the best evidence available is for the use of elbasvir and grazoprevir. This combination as well as the combination of paritaprevir/ritonavir/ombitasvir/dasabuvir for HCV GT-1b are recommended. More studies are needed to assess efficacy and adverse effects of DAAs and their impact on CKD patients and to fully elucidate the effect of curing CHC on the natural history and sequelae of renal disease in CHC patients with CKD.

CANADIAN JOURNAL OF INFECTIOUS DISEASES & MEDICAL MICROBIOLOGY 2016; 2016:8254343. [PMID: 27597875 PMCID: PMC5002453 DOI: 10.1155/2016/8254343] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/24/2016] [Revised: 07/05/2016] [Accepted: 07/14/2016] [Indexed: 11/30/2022]
Abstract
Background. Transfusion-transmissible infections, human immunodeficiency virus, hepatitis B virus, hepatitis C virus, and syphilis are among the greatest threats to blood safety and pose a serious public health problem. Objective. To determine the magnitude of blood borne infections among blood donors at Wolaita Sodo University Teaching Referral Hospital. Methods and Materials. A cross-sectional study was conducted from 10/11/2015 up to 10/12/2015. 390 donors were consecutively included and data on donor's age, sex, blood type, and serum screening results were obtained by structured questionnaire and laboratory investigation. The collected data were entered into Epi Data version 1.4 and then exported to SPSS version 20.0 for analysis. Result. The seroprevalence of blood borne pathogens is 29.5% of which HCV, HBV, HIV, and syphilis account for 8.5%, 9.5%, 6.4%, and 7.5%, respectively. Multiple infections were observed among 2.8% of the infected individuals. In addition, age ≥ 30 has a significant association with HCV. Conclusion. Significantly higher prevalence of transfusion-transmissible infections was identified from blood donors and they remain to be the greatest threat to blood safety, so comprehensive screening of donors' blood for HIV, HBV, HCV, and syphilis using standard methods is highly recommended to ensure the safety of blood recipient.

Abstract
Due to the intimate relationship between liver and kidney disease in hepatitis C virus (HCV) infection, treatment options for HCV-positive patients at any stage of chronic kidney disease (CKD) are essential. The availability of second-generation, direct-acting antiviral (DAA) combinations has allowed for the advent of interferon-sparing treatment regimens with shorter durations and minimal side effects. While many of the second-generation DAAs are principally metabolized by the hepatic system, dosing in severe renal impairment (creatinine clearance [CrCl] <30 mL/min) or dialysis has remained questionable due to limited experience. New evidence regarding the use of these agents in renal impairment continues to become available, as real-world experience with these treatment regimens is reported. Simeprevir, ledipasvir, paritaprevir, ombitasvir, dasabuvir, and daclatasvir have data to suggest safety in end-stage renal disease. While safety and efficacy with sofosbuvir remains uncertain, data are now available to support utilizing a dose adjustment when glomerular filtration rates are <30 mL/min. Upcoming regimens grazoprevir/elbasvir and daclatasvir/asunaprevir/beclavubir may provide further options for patients with advanced kidney disease, and ongoing studies will continue to provide guidance for this unique patient population. This article will review the currently available literature, including the newest emerging evidence, on the use of second-generation DAAs in CKD stages 3 to 5 and dialysis.

Abstract
In addition to causing cirrhosis and hepatocellular carcinoma, hepatitis C virus (HCV) is thought to cause hypolipidemia, hepatic steatosis, insulin resistance, metabolic syndrome, and diabetes. The viral life cycle of HCV depends on cholesterol metabolism in host cells. HCV core protein and nonstructural protein 5A perturb crucial lipid and glucose pathways, such as the sterol regulatory element-binding protein pathway and the protein kinase B/mammalian target of rapamycin/S6 kinase 1 pathway. Although several lines of transgenic mice expressing core or full HCV proteins exhibit hepatic steatosis and/or dyslipidemia, whether they completely reflect the metabolic alterations in humans with HCV infection remains unknown. Many cross-sectional studies have demonstrated increased prevalences of metabolic alterations and cardiovascular events in patients with chronic hepatitis C (CHC); however, conflicting results exist, primarily due to unavoidable individual variations. Utilizing anti-HCV therapy, most longitudinal cohort studies of CHC patients have demonstrated the favorable effects of viral clearance in attenuating metabolic alterations and cardiovascular risks. To determine the risks of HCV-associated metabolic alterations and associated complications in patients with CHC, it is necessary to adjust for crucial confounders, such as HCV genotype and host baseline glucose metabolism, for a long follow-up period after anti-HCV treatment. Adipose tissue is an important endocrine organ due to its release of adipocytokines, which regulate lipid and glucose metabolism. However, most data on HCV infection and adipocytokine alteration are inconclusive. A comprehensive overview of HCV-associated metabolic and adipocytokine alterations, from bench to bedside, is presented in this topic highlight.

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
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
Hepatitis C infection and chronic kidney disease are major health burden worldwide. Hepatitis C infection is associated with a wide range of extra-hepatic manifestations in various organs including the kidneys. A strong association between hepatitis C and chronic kidney disease has come to light. Hemodialysis in supporting the end stage renal disease patients unfortunately carries a risk for hepatitis C infection. Despite much improvement in the care of this group of patients, the prevalence of hepatitis C infection in hemodialysis patients is still higher than the general population. Hepatitis C infection has a negative effect on the survival of hemodialysis and renal transplant patients. Treatment of hepatitis C in end stage renal disease patients using conventional or pegylated interferon with or without ribavirin remains a clinical challenge with low response rate, high dropout rate due to poor tolerability and many unmet needs. The approval of new direct acting antiviral agents for hepatitis C may dramatically change the treatment approach in hepatitis C infected patients with mild to moderate renal impairment. However it remains to be confirmed if the newer Hepatitis C therapies are safe in individuals with severe renal impairment. This review article discusses the relationship between hepatitis C and chronic kidney disease, describe the various types of renal diseases associated with hepatitis C and the newer as well as the existing treatments for hepatitis C in the context of this subpopulation of hepatitis C patients.
