Abstract
Cystic fibrosis-related hepatobiliary involvement (CFHBI) is a term used to describe a spectrum of hepatobiliary involvement ranging from a transient elevation of transaminase levels to advanced cystic fibrosis-associated liver disease (aCFLD). While CFHBI is common among people with cystic fibrosis (PwCF), aCFLD is rare impacting only approximately 5%-10% of the CF population. After respiratory/cardiorespiratory issues and transplant-related complications, aCFLD is now the 4th leading cause of mortality among PwCF. Additionally, aCFLD is an independent predictor of all-cause mortality and is associated with significant morbidity. Despite this recognition, our ability to predict those patients at greatest risk for aCFLD, identify early aCFLD, and monitor the incremental progression of CFHBI is lacking. Here, we review the strengths and weaknesses of the common biomarkers and imaging modalities used in the evaluation and monitoring of CFHBI, as well as the current understanding of genetic modifiers related to aCFLD.

Splenic Arterial Pulsatility Index to Predict Hepatic Fibrosis in Hemodialysis Patients with Chronic Hepatitis C Virus Infection. J Clin Med 2023; 12:jcm12052020. [PMID: 36902807 PMCID: PMC10004191 DOI: 10.3390/jcm12052020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2022] [Revised: 02/27/2023] [Accepted: 03/02/2023] [Indexed: 03/08/2023] Open
Abstract
The clinical utility of the splenic arterial pulsatility index (SAPI), a duplex Doppler ultrasonographic index, to predict the stage of hepatic fibrosis in hemodialysis patients with chronic hepatitis C virus (HCV) infection remains elusive. We conducted a retrospective, cross-sectional study to include 296 hemodialysis patients with HCV who underwent SAPI assessment and liver stiffness measurements (LSMs). The levels of SAPI were significantly associated with LSMs (Pearson correlation coefficient: 0.413, p < 0.001) and different stages of hepatic fibrosis as determined using LSMs (Spearman's rank correlation coefficient: 0.529, p < 0.001). The areas under receiver operating characteristics (AUROCs) of SAPI to predict the severity of hepatic fibrosis were 0.730 (95% CI: 0.671-0.789) for ≥F1, 0.782 (95% CI: 0.730-0.834) for ≥F2, 0.838 (95% CI: 0.781-0.894) for ≥F3, and 0.851 (95% CI: 0.771-0.931) for F4. Furthermore, the AUROCs of SAPI were comparable to those of the fibrosis index based on four parameters (FIB-4) and superior to those of the aspartate transaminase (AST)-to-platelet ratio index (APRI). The positive predictive value (PPV) for ≥F1 was 79.5% when the Youden index was set at 1.04, and the negative predictive values (NPVs) for ≥F2, ≥F3, and F4 were 79.8%, 92,6%, and 96.9%, respectively, when the maximal Youden indices were set at 1.06, 1.19, and 1.30. The diagnostic accuracies of SAPI with the maximal Youden index for a fibrosis stage of ≥F1, ≥F2, ≥F3, and F4 were 69.6%, 67.2%, 75.0%, and 85.1%, respectively. In conclusion, SAPI can serve as a good noninvasive index in predicting the severity of hepatic fibrosis in hemodialysis patients with chronic HCV infection.

Abstract
Hepatitis C virus (HCV) is a major health problem in hemodialysis patients, which leads to significant morbidity and mortality through progressive hepatic fibrosis or cirrhosis. Percutaneous liver biopsy is the gold standard to stage hepatic fibrosis. However, it is an invasive procedure with postbiopsy complications. Because uremia may significantly increase the risk of fatal and nonfatal bleeding events, the use of noninvasive means to assess the severity of hepatic fibrosis is particularly appealing to hemodialysis patients. To date, researchers have evaluated the performance of various biochemical, serological, and radiological indices for hepatic fibrosis in hemodialysis patients with HCV infection. In this review, we will summarize the progress of noninvasive indices for assessing hepatic fibrosis and propose a pragmatic recommendation to diagnose the stage of hepatic fibrosis with a noninvasive index, in hemodialysis patients with HCV infection.

Impact of aspartate aminotransferase-to-platelet ratio index based score to assess posthepatectomy liver failure in patients with hepatocellular carcninoma. World J Surg Oncol 2022; 20:248. [PMID: 35918753 PMCID: PMC9344632 DOI: 10.1186/s12957-022-02714-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Accepted: 06/30/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Posthepatectomy liver failure (PHLF) is a life-threatening complication following hepatic resection. The aspartate aminotransferase-to-platelet ratio index (APRI) is a non-invasive model for assessing the liver functional reserve in patients with hepatocellular carcinoma (HCC). This study aimed to establish a scoring model to stratify patients with HCC at risk for PHLF. METHODS This single-center retrospective study included 451 patients who underwent hepatic resection for HCC between 2004 and 2017. Preoperative factors, including non-invasive liver fibrosis markers and intraoperative factors, were evaluated. The predictive impact for PHLF was evaluated using receiver operating characteristic (ROC) curves of these factors. RESULTS Of 451 patients, 30 (6.7%) developed severe PHLF (grade B/C). Multivariate logistic analysis indicated that APRI, model for end-stage liver disease (MELD) score, operating time, and intraoperative blood loss were significantly associated with severe PHLF. A scoring model (over 0-4 points) was calculated using these optimal cutoff values. The area under the ROC curve of the established score for severe PHLF was 0.88, which greatly improved the predictive accuracy compared with these factors alone (p < 0.05 for all). CONCLUSIONS The scoring model-based APRI, MELD score, operating time, and intraoperative blood loss can predict severe PHLF in patients with HCC.

Aminotransferase-to-platelet ratio index and Fibrosis-4 index score predict hepatic fibrosis evaluated by transient hepatic elastography in hepatitis C virus-infected hemodialysis patients. Eur J Gastroenterol Hepatol 2021; 33:e260-e265.

Abstract
OBJECTIVE This study aimed to evaluate the performance of aminotransferase-to-platelet ratio index (APRI) and Fibrosis-4 index (FIB-4) in chronic kidney disease stage 5D HCV-infected patients compared to transient hepatic elastography (TE) as the gold standard. METHODS Hemodialysis HCV-infected patients submitted to TE (FibroScan, Echosens, Paris, France) had APRI and FIB-4 calculated. Based on the best area under receiver operating characteristic curve (AUROC) for significant fibrosis and cirrhosis, APRI and FIB-4 cutoffs were determined and their performances were compared. RESULTS Seventy patients were included. Both APRI and FIB-4 showed good performance for identifying significant fibrosis [AUROC = 0.73, 95% confidence interval (CI) 0.61-0.83 and 0.79, 95% CI 0.68-0.88; P < 0.05] and cirrhosis [AUROC = 0.82, 95% CI 0.71-0.90 and 0.85, 95% CI 0.75-0.93; P < 0.05]. APRI ≤ 0.25 excluded significant fibrosis with negative predictive value (NPV) of 81.8% and APRI > 0.61 confirmed it with a positive predictive value (PPV) of 81.8%. Similarly, NPV for FIB-4 ≤ 0.60 regarding significant fibrosis was 90.9%. NPV for cirrhosis for APRI ≤ 0.42 or FIB-4 ≤ 1.40 was 97%. However, APRI > 0.73 or FIB-4 > 2.22 showed a modest PPV of 60 and 70% to confirm cirrhosis, respectively. CONCLUSION APRI and FIB-4 are simple, non-expensive scoring systems with good accuracy to assess fibrosis in HCV-infected hemodialysis patients, mainly excluding both significant fibrosis or cirrhosis and may be an alternative to TE in the evaluation of this population.

Abstract
Renal dysfunction is very common among patients with chronic liver disease, and concomitant liver disease can occur among patients with chronic kidney disease. The spectrum of clinical presentation and underlying etiology is wide when concomitant kidney and liver disease occur in the same patient. Management of these patients with dual onslaught is challenging and requires a team approach of hepatologists and nephrologists. No recent guidelines exist on algorithmic approach toward diagnosis and management of these challenging patients. The Indian National Association for Study of Liver (INASL) in association with Indian Society of Nephrology (ISN) endeavored to develop joint guidelines on diagnosis and management of patients who have simultaneous liver and kidney disease. For generating these guidelines, an INASL-ISN Taskforce was constituted, which had members from both the societies. The taskforce first identified contentious issues on various aspects of simultaneous liver and kidney diseases, which were allotted to individual members of the taskforce who reviewed them in detail. A round-table meeting of the Taskforce was held on 20-21 October 2018 at New Delhi to discuss, debate, and finalize the consensus statements. The evidence and recommendations in these guidelines have been graded according to the Grading of Recommendations Assessment Development and Evaluation (GRADE) system with minor modifications. The strength of recommendations (strong and weak) thus reflects the quality (grade) of underlying evidence (I, II, III). We present here the INASL-ISN Joint Position Statements on Management of Patients with Simultaneous Liver and Kidney Disease.

Abstract
Background The accurate assessment of liver fibrosis among hemodialysis patients with chronic hepatitis C (CHC) is important for both treatment and for follow up strategies. Applying the non-invasive methods in general population with viral hepatitis have been successful but the applicability of the aminotransferase/platelet ratio index (APRI) or the fibrosis-4 index (FIB-4) in hemodialysis patients need further evaluation. Materials and methods We conducted a prospective, multi-center, uremic cohort to verify the applicability of APRI and FIB-4 in identifying liver fibrosis by reference with the standard transient elastography (TE) measures. Results There were 116 CHC cases with valid TE were enrolled in our analysis. 46 cases (39.6%) were classified as F1, 35 cases (30.2%) as F2, 11 cases (9.5%) as F3, and 24 cases (20.7%) as F4, respectively. The traditional APRI and FIB-4 criteria did not correctly identify liver fibrosis. The optimal cut-off value of APRI was 0.28 and of FIB-4 was 1.91 to best excluding liver cirrhosis with AUC of 76% and 77%, respectively. The subgroup analysis showed that female CHC hemodialysis patients had better diagnostic accuracy with 74.1% by APRI. And CHC hemodialysis patients without hypertension had better diagnostic accuracy with 78.6% by FIB-4. Conclusions This study confirmed the traditional category level of APRI and FIB-4 were unable to identify liver fibrosis of CHC hemodialysis patients. With the adjusted cut-off value, APRI and FIB-4 still showed suboptimal diagnostic accuracy. Our results suggest the necessary of TE measures for liver fibrosis in the CHC uremic population.

Diagnostic Accuracy of Noninvasive Tests to Detect Advanced Hepatic Fibrosis in Patients With Hepatitis C and End-Stage Renal Disease. Clin Gastroenterol Hepatol 2020; 18:2332-2339.e1. [PMID: 32084602 DOI: 10.1016/j.cgh.2020.02.019] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2019] [Revised: 01/06/2020] [Accepted: 02/05/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS For patients with liver disease from hepatitis C virus (HCV) infection complicated by end-stage renal disease (ESRD), it is important to assess liver fibrosis before kidney transplantation. We evaluated the accuracy of non-invasive tests to identify advanced hepatic fibrosis in patients with HCV and ESRD. METHODS In a retrospective study, we collected data on ratio of aspartate aminotransferase:alanine aminotransferase (AST:ALT), AST platelet ratio index (APRI), FIB-4 score, fibrosis index score, and King's score from 139 patients with ESRD and HCV infection (mean age, 52.8 y; 76.3% male; 86.4% African American; 45.3% with increased level of ALT). Results were compared with findings from histologic analyses of biopsies (reference standard). The primary outcome was detection of advanced fibrosis, defined as either bridging fibrosis or cirrhosis. Area under the receiver operating characteristic (AUROC) curves were constructed and optimal cutoff values were determined for each test. Sensitivity, specificity, positive and negative predictive values, and diagnostic accuracy were calculated. We repeated the analysis with stratification for normal levels of ALT (≤ 35 U/L for men and ≤ 25 u/L for women) and increased levels of ALT. RESULTS FIB-4 scores identified patients with advanced fibrosis with an AUROC of 0.71 (95% CI, 0.61-0.80), the King's score with an AUROC of 0.69 (95% CI, 0.58-0.80), and the APRI with and AUROC of 0.68 (95% CI, 0.59-0.79). The accuracy of these tests increased when they were used to analyze patients with increased levels of ALT. All tests produced inaccurate results when they were used to assess patients with normal levels of AST and ALT. CONCLUSIONS In patients with ESRD and HCV infection, FIB-4 scores, King's scores, and the APRI identify those with advanced fibrosis with AUROC values ranging from 0.68-0.71. Accuracy increased modestly when patients with increased levels of ALT were tested, but the tests produced inaccurate results for patients with a normal level of ALT.

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.

Profile of hepatocellular carcinoma in the Republic of Moldova: first-hand information on the presentation, distribution and etiologies. ROMANIAN JOURNAL OF INTERNAL MEDICINE = REVUE ROUMAINE DE MEDECINE INTERNE 2019; 57:37-46.

Abstract
INTRODUCTION Moldova is the European country with the highest incidence of hepatocellular carcinoma (HCC) in both sexes. There is, however, no data comprehensively describing the presentation and the risk factors of HCC in the country. We decided to analyze cases of HCC recently received in a tertiary healthcare Institution from Chisinau, the Moldovian capital. METHODS A series of 148 primary liver tumors including 139 cases of HCC were retrospectively analyzed for demographic features, serological and biochemical data, and clinical presentation. RESULTS The mean age of patients was 59 ± 10 years (range: 19-66) with a M:F sex ratio of 1.9. Tumors appeared on full-blown liver cirrhosis in 83% of cases and were composed of multiple nodules at diagnosis in 36% of patients. Serum Alpha-fetoprotein was exceeding 10ng/mL in 76% of cases. Liver tumor and hepatitis were co-discovered in 34% of cases. More than 81% of hepatocellular carcinomas were associated with at least one hepatitis virus. Carriers of anti-hepatitis C virus were predominating (55% of cases) over patients seropositive for hepatitis B virus surface antigen (36%). Half of the latter were also infected with hepatitis Delta virus. In total, dual or triple infections were present in 24% and 7% of cases. CONCLUSIONS The burden of infections with hepatitis viruses is particularly important in Moldova and corresponds to a situation commonly observed in countries of the Southern hemisphere. A pro-active policy of screening for persistent liver infection targeting population at risk of HCC (> 50 years) and coupled with the distribution of antivirals in positive cases should be rapidly implemented in Moldova to reduce incidence or primary liver cancer.

Abstract
Chronic hepatitis C (CHC) is the most common cause of infection related deaths in USA according to Central Disease Control and Prevention (CDC) report in 2016. Hepatitis C is a blood borne virus and is common in chronic kidney disease (CKD) and in hemodialysis (HD) dependent patients. A majority of patients with CHC could remain asymptomatic and are still undiagnosed. Early detection of CHC and linkage of infected patients to care for evaluation and treatment is the standard of care as emphasized by Kidney Disease Improving Global Outcome (KDIGO) and American Association for the Study of Liver Disease- Infectious Disease Society of America (AASLD-IDSA) practice guidelines. Historically, the management of hepatitis C virus (HCV)-infected CKD patients, including those on dialysis and in the peri-transplant setting, was a challenge. However, the evolution of various liver assessment tools, HCV tests, therapies and treatment strategies in the recent years has catalyzed a paradigm change in this area. This review provides an update on evaluating methodology, diagnostic tests and the various assessment tools for liver fibrosis pertaining to the CKD/HD patient infected with HCV.

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 The aim of this study is to investigate the association between hepatic activity index (HAI) and fibrosis score (FS) with inflammation biomarkers in non-uremic and uremic hepatitis C positive patients. METHODS Fifty chronic hepatitis C (cHepC) positive patients, having a liver biopsy were included in this study. Liver biopsies were scored according to modified ISHAC scoring system. 25 healthy controls of similar age and gender were also enrolled as control group. Serum YKL-40, neutrophil/lymphocyte ratio (NLR), thrombocyte/lymphocyte ratio (PLR), CRP and Immunoglobulin (IgG, A and M) levels were used to determine inflammation. AST to Platelet Ratio Index (APRI) score was also evaluated. According to biopsy findings patients were divided into 2 groups: low (0-2) and severe (3-6) FS. RESULTS Patients with cHepC had increased inflammation compared to the healthy controls. End-stage renal disease (ESRD) patients had higher levels of inflammation markers (NLR, IgG, CRP and YKL-40) and lower HCV RNA levels, HAI and FS compared to non-uremic patients. When patients were grouped into 2 according to FS as mild and severe, IgG (p < 0.001), YKL-40 (p = 0.02) levels and APRI score (p = 0.002) were significantly higher compared to mild FS (p = 0.002). YKL-40 levels (t value: 3.48; p = 0.001) and APRI score (t value: 4.57, p < 0.001) were found as independent associated with FS in non-uremic patients. However, in adjusted models, only APRI score (t value: 3.98, p = 0.002) was an independent associated with FS in ESRD patients. CONCLUSION In non-uremic cHepC patients, YKL-40 levels and APRI score may be valuable markers of FS. In ESRD patients, there is not sufficient data for prediction of HAI and FS.

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

Abstract
BACKGROUND Hepatitis C virus infection (HCV) is a common problem among kidney transplant (KT) recipients. The long-term burden of HCV infection on graft survival after kidney transplantation is controversial. METHODS We performed a retrospective study including all renal transplant recipients with HCV infection (n = 34) compared with a control group (n = 80). The prevalence of HCV infection was 2.7%. The median follow-up period was 134 months (11 years). Graft survival and associated risk factors were assessed by means of Cox proportional hazard analysis. RESULTS We found that HCV-positive patients remained on dialysis for longer periods (P = .001) and received transplants at a younger age (P = .03). Actuarial graft survival rates at 1, 5, and 10 years after KT were, respectively, 94.1%, 78.1%, and 66.9%, in the HCV-positive group and 94.9%, 89.1%, and 80.4% in the HCV-negative group. Graft survival did not differ significantly between groups (P = .154). A higher incidence of major cardiovascular disease among HCV-positive patients (P = .004) was noted. Multivariate analysis showed that HCV infection was not an important risk factor for graft loss (adjusted hazard ratio, 2.810; 95% confidence interval, 0.925-8.541; P = .069). Among the HCV-positive population, immunosuppression with cyclosporine or azathioprine conveyed better graft survival. CONCLUSIONS Our findings suggest that the long-term impact of HCV infection on graft survival after KT is not significant. KT remains a safe and effective modality of renal replacement in HCV-infected patients with end-stage renal disease.

Abstract
The liver biopsy has long been the "gold standard" for assessing liver fibrosis in patients with hepatitis C. It's an invasive procedure which is associated with an elevated bleeding, especially in chronic hemodialysis patients. Main goal is to assess liver fibrosis in chronic hemodialysis with HCV by Fibroscan and by biological scores (APRI, Forns and Fib-4), and to measure the correlation between these tests. Cross-sectional study including all chronic hemodialysis patients with hepatitis C virus, in two public hemodialysis centers of Fez. All patients were evaluated for liver fibrosis using noninvasive methods (FibroScan and laboratory tests). Subsequently, the correlation between different tests has been measured. 95 chronic hemodialysis were studied, twenty nine patients (30.5%) with chronic hepatitis C. The average age was 52.38 ± 16.8 years. Nine liver fibrosis cases have been concluded by forns score. Fibroscan has objectified significant fibrosis in 6 cases. On the other side APRI has objectified sgnifivant fibrosis only in 3 cases. The Fib-4 showed severe fibrosis in five cases. The results have been most consistent between APRI and Fib-4, followed by Fibroscan and Forns, then APRI and FibroScan.

Abstract
BACKGROUND There are no standard guidelines for the permissible degree of liver fibrosis in patients with chronic hepatitis C virus prohibiting cadaveric renal transplantation (CRT). METHODS A decision analysis model was constructed to compare 5-year patient survival using three strategies for patients on hemodialysis. The probabilities of pretransplant and posttransplant survival, progression of liver fibrosis, CRT, and sustained viral response were obtained from a systematic review of the literature. Sensitivity analyses were performed. RESULTS Kidney transplantation was associated with improved 5-year survival for patients with fibrosis stages 1 to 3, but not stage 4 (cirrhosis). Antiviral therapy was associated with improvement in survival in patients with stage 3 fibrosis. The 5-year survival was similar for patients with stage 4 irrespective of the option of antiviral therapy. The model was sensitive to varying the probability of both pretransplant and posttransplant survival. CONCLUSION There appears to be no overall 5-year survival benefit in treating S1 and S2 fibrosis patients with hepatitis C virus antiviral therapy before CRT. There is no benefit in overall 5-year survival in patients with cirrhosis and thus should not be candidates for CRT.

Abstract
PURPOSE Serum hyaluronic acid (sHA) is studied as a noninvasive marker of liver fibrosis (F) in chronic B and C viral hepatitis in general population but less in end-stage renal disease patients undergoing hemodialysis. METHODS We evaluated sHA as a noninvasive biomarker of F in a multicenter prospective, transversal, and observational study which included 52 end-stage renal disease patients with chronic B (14) and C (38) viral hepatitis (age 55.57 ± 14.46 years, dialysis vintage 132.59 ± 86.02 months). RESULTS Of the noninvasive tests analyzed, only sHA, APRI, and FIB4 index were able to differentiate patients with F1 (sHA p = 0.006; APRI p = 0.031; FIB4 p = 0.016). No statistically significant differences were found between sHA and APRI, ASAT/ALAT ratio, and FIB4 index in detecting F1 a (p > 0.02). sHA seemed to be more efficient than APRI, ASAT/ALAT ratio, and FIB4 index, having the highest estimated AUC value. The sHA threshold value for F1 was equal to 33.46 ng/mL, with the following estimated values of the performance indicators: Se 88.46 % and Sp 50 %. sHA was the only noninvasive test of the studied tests that could determine F2 (p = 0.002), with a threshold value of 80.24 ng/mL (Se 63 %, Sp 88 %), and F3 (p = 0.008), with a threshold value of 88.54 ng/mL (Se 60 %, Sp 84 %). None of the studied noninvasive tests could determine F4. CONCLUSIONS In patients with chronic B and C viral hepatitis undergoing hemodialysis, sHA may be a useful biomarker for the liver fibrosis grades: F1-mild, F2-moderate, and F3-severe, but it does not differentiate between chronic hepatitis (F1-F3) and liver cirrhosis (F4).

Abstract
Hepatitis C virus (HCV) infection in patients with end-stage renal disease (ESRD) is associated with more rapid liver disease progression and reduced renal graft and patients' survival following kidney transplantation. Evaluations and management of HCV in patients with renal disease are challenging. The pharmacokinetics of interferons (IFN), ribavirin (RBV) and some direct acting antiviral (DAA), such as sofosbuvir, are altered in patients with ESRD. With dose adjustment and careful monitoring, treatment of HCV in patients with ESRD can be associated with sustained virological response (SVR) rates nearly comparable to that of patients with normal renal function. DAA-based regimens, especially the IFN-free and RBV-free regimens, are theoretically preferred for patients with ESRD and KT in order to increase SVR rates and to reduce treatment side effects. However, based on the data for pharmacokinetics, dosing safety and efficacy of DAA for patients with severe renal impairment are lacking. This review will be focused on the evaluations, available pharmacologic data, and management of HCV in patients with severe renal impairment, patients who underwent KT, and those who suffered from HCV-related renal disease, according to the available treatment options, including DAA.

Abstract
OBJECTIVE Data comparing the efficacy and safety of combination therapy with peginterferon plus low-dose ribavirin and peginterferon monotherapy in treatment-naive haemodialysis patients with hepatitis C virus genotype 2 (HCV-2) infection are limited. DESIGN In this randomised trial, 172 patients received 24 weeks of peginterferon alfa-2a 135 μg/week plus ribavirin 200 mg/day (n=86) or peginterferon alfa-2a 135 μg/week (n=86). The efficacy and safety endpoints were sustained virological response (SVR) rate and adverse event (AE)-related withdrawal rate. RESULTS Compared with monotherapy, combination therapy had a greater SVR rate (74% vs 44%, relative risk (RR): 1.68 [95% CI 1.29 to 2.20]; p<0.001). The beneficial effect of combination therapy was more pronounced in patients with baseline viral load ≥800,000 IU/mL than those with baseline viral load <800,000 IU/mL (RR: 3.08 [95% CI 1.80 to 5.29] vs. RR: 1.11 [95% CI 0.83 to 1.45]; interaction p=0.001). Patients receiving combination therapy were more likely to have a haemoglobin level of <8.5 g/dL (70% vs. 8%, risk difference (RD): 62% [95% CI 50% to 73%]; p<0.001) and required a higher dosage [mean: 13,417 vs. 6667 IU/week, p=0.027] of epoetin β to manage anaemia than those receiving monotherapy. The AE-related withdrawal rates were 6% and 3% in combination therapy and monotherapy groups, respectively (RD: 2% [95% CI -4% to 9%]). CONCLUSIONS In treatment-naive haemodialysis patients with HCV-2 infection, combination therapy with peginterferon plus low-dose ribavirin achieved a greater SVR rate than peginterferon monotherapy. Most haemodialysis patients can tolerate combination therapy. TRIAL REGISTRATION NUMBER ClinicalTrial.gov number, NCT00491244.

Abstract
Assessment of liver fibrosis in chronic hepatitis C virus (HCV) infection is considered a relevant part of patient care and key for decision making. Although liver biopsy has been considered the gold standard for staging liver fibrosis, it is an invasive technique and subject to sampling errors and significant intra- and inter-observer variability. Over the last decade, several noninvasive markers were proposed for liver fibrosis diagnosis in chronic HCV infection, with variable performance. Besides the clear advantage of being noninvasive, a more objective interpretation of test results may overcome the mentioned intra- and inter-observer variability of liver biopsy. In addition, these tests can theoretically offer a more accurate view of fibrogenic events occurring in the entire liver with the advantage of providing frequent fibrosis evaluation without additional risk. However, in general, these tests show low accuracy in discriminating between intermediate stages of fibrosis and may be influenced by several hepatic and extra-hepatic conditions. These methods are either serum markers (usually combined in a mathematical model) or imaging modalities that can be used separately or combined in algorithms to improve accuracy. In this review we will discuss the different noninvasive methods that are currently available for the evaluation of liver fibrosis in chronic hepatitis C, their advantages, limitations and application in clinical practice.

Abstract
BACKGROUND & AIMS Host and viral factors interplay in the spontaneous clearance of hepatitis C virus (HCV) infection. We aimed to explore the roles of IL28B genotypes and hepatitis B virus (HBV) infections in spontaneous HCV seroclearance. METHODS IL28B rs8099917 genotypes, HCV and HBV markers were determined in 290 patients who were seropositive for HCV antibodies from 1681 total uremic patients on maintenance hemodialysis. RESULTS Persistent HCV viremia was observed in 74.6% (214/287) of patients. Logistic regression revealed that the strongest factors associated with spontaneous HCV seroclearance were carriage of rs8099917 TT-type (odds ratio/95% confidence intervals [OR/CI]: 6.22/1.41-27.35, p=0.016), followed by concurrent hepatitis B surface antigen (HBsAg) seropositivity (OR/CI: 2.37/1.06-5.26, p=0.035). The clearance rate was highest among patients with both positive HBsAg/rs8099917 TT-type (44.8%, OR/CI: 20.88/3.5-402.5), followed by positive HBsAg/rs8099917 non-TT-type (28.6%, OR/CI: 8.86/1.8-160.8), and negative HBsAg/rs8099917 TT-type (26.7%, OR/CI: 12.75/1.0-319.4), compared to 4% of negative HBsAg/rs8099917 non-TT-type (trend p=0.0002). HBsAg levels, but not HBV DNA levels, were significantly associated with spontaneous HCV seroclearance. Spontaneous HCV seroclearance rate was 58.3% in patients with HBsAg>200IU/ml/rs8099917 TT-type (OR/CI: 42.54/5.7-908.4), 28.0% in patients with HBsAg<200IU/ml/rs8099917 TT-type or HBsAg>200IU/ml/rs8099917 non-TT-type (OR/CI: 11.12/2.3-201.0), compared to only 3.3% in those with HBsAg<200IU/ml/rs8099917 non-TT-type (trend p=0.0004). Five of 214 (2.3%) HCV viremic patients at enrollment had spontaneous HCV seroclearance during one-year follow-up, which was associated with baseline HCV RNA and HBsAg levels. CONCLUSIONS High HBsAg levels and favorable IL28B genotype were additively associated with spontaneous HCV seroclearance in uremic patients.

Sette LHBC, Almeida Lopes EPD. Liver enzymes serum levels in patients with chronic kidney disease on hemodialysis: a comprehensive review. Clinics (Sao Paulo) 2014; 69:271-8. [PMID: 24714836 PMCID: PMC3971360 DOI: 10.6061/clinics/2014(04)09] [Citation(s) in RCA: 45] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2013] [Accepted: 08/27/2013] [Indexed: 12/17/2022] Open
Abstract
We reviewed the literature regarding the serum levels of the enzymes aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyl transferase in patients with chronic kidney disease on hemodialysis with and without viral hepatitis. Original articles published up to January 2013 on adult patients with chronic kidney disease on hemodialysis were selected. These articles contained the words "transaminases" "aspartate aminotransferase" "alanine aminotransferase" "gamma glutamyl transferase," "liver enzymes", AND "dialysis" OR "hemodialysis". A total of 823 articles were retrieved. After applying the inclusion and exclusion criteria, 49 articles were selected. The patients with chronic kidney disease on hemodialysis had reduced serum levels of aminotransferases due to hemodilution, lower pyridoxine levels, or elevated homocysteine levels. The chronic kidney disease patients on hemodialysis infected with the hepatitis C virus also had lower aminotransferase levels compared with the infected patients without chronic kidney disease. This reduction is in part due to decreased viremia caused by the dialysis method, the production of a hepatocyte growth factor and endogenous interferon-α, and lymphocyte activation, which decreases viral action on hepatocytes. Few studies were retrieved on gamma-glutamyl transferase serum levels; those found reported that there were no differences between the patients with or without chronic kidney disease. The serum aminotransferase levels were lower in the patients with chronic kidney disease on hemodialysis (with or without viral hepatitis) than in the patients with normal renal function; this reduction has a multifactorial origin.

Abstract
BACKGROUND Advanced fibrosis or cirrhosis is still regarded as a contraindication for kidney transplantation alone by most centers. The value of aminotransferase to platelet ratio index (APRI) and other non-invasive markers has been less studied in hepatitis C virus (HCV)-positive patients with concurrent end-stage renal disease to predict hepatic fibrosis. Can these be used to effectively decrease the number of biopsies done in these patients being evaluated for transplantation? METHODS Our study population included 255 patients with liver biopsy data. All patient information was collected and reviewed from medical records. The diagnostic accuracy of the predictive models was analyzed by calculating sensitivity, specificity, positive predictive value and negative predictive value. RESULTS The variables associated with F3-F4 were aspartate aminotransferase (P = 0.007), bilirubin (P ≤ 0.001), platelet count (P = 0.01) and APRI (P ≤ 0.001). The use of any one laboratory abnormality to predict liver biopsy scores did not show high positive predictive values (22.6-72.7%). Having abnormal liver findings or cirrhosis on imaging was associated with high specificities (92.0-97.8%) but low sensitivities (31.4-42.9%). Using APRI levels of ≥0.40 and ≤0.95 as an indication for liver biopsy, 50% of patients with F3-F4 would have correctly avoided having a biopsy. However, 33% of patients with F3-F4 would have been mislabeled and not be indicated for biopsy. CONCLUSIONS Our data suggest that there may not currently be a simple and sufficiently accurate non-invasive test to replace liver biopsy in renal transplant workup for HCV-positive patients. The risks outweigh the benefits when it comes to using non-invasive markers like the APRI.

Abstract
Hepatitis C virus (HCV) infection is frequent among patients with end-stage renal disease on haemodialysis and is considered to be an independent risk factor for mortality in this setting. However, only a few of these patients are treated with anti-hepatitis virus treatment before the development of end-stage renal disease. Recent guidelines recommend identification of patients with good prognoses who are in need of interferon treatment, but we know little of patients who must be treated urgently. Ninety-eight patients on haemodialysis (48 anti-HCV-positive and 50 anti-HCV-negative patients) were enrolled in this study; HCV RNA was detected in 43 anti-HCV-positive patients. Univariate analysis and multivariate regression analysis were applied to identify variables independently associated with persistent HCV infection. Seven variables were proven to be associated with persistent HCV infection. Among them, type IV collagen 7S and N-terminal propeptide of type III procollagen (P-III-P) were defined as independent variables useful in distinguishing HCV RNA-positive patients from HCV RNA-negative patients with 0.91 sensitivity, 0.91 specificity, 0.89 positive predictive value and 0.93 negative predictive value. Our observations suggest that hepatocyte destruction with enhanced liver fibrosis is a characteristic clinical feature of persistent HCV infection. Type IV collagen 7S of ≥ 5 ng/mL and/or P-III-P of ≥ 5 U/mL would be useful markers to identify patients in need of interferon treatment, which supports the idea of the Kidney Disease: Improving Global Outcomes guidelines that a good prognosis in patients with HCV infection on haemodialysis should prompt consideration for IFN treatment when applicable.

Abstract
INTRODUCTION Although it is standard procedure in the evaluation of liver diseases, biopsy is an invasive method subject to sampling error and intra or inter-observer variability. Thus, surrogate markers of liver fibrosis have been proposed, with variable availability and accuracy. AIM Validate and compare the performance of APRI and FIB-4 as predictors of liver fibrosis in HCV patients. MATERIAL AND METHODS Cross-sectional study including patients with HCV-RNA (+) who underwent liver biopsy. Significant fibrosis was defined as METAVIR stage ≥ 2. The diagnostic performance of the models in predicting significant fibrosis were evaluated and compared by ROC curves. RESULTS The study included 119 patients, mean age 43.7 ± 10.6 years and 62% males. Significant fibrosis was identified in 41 patients. The AUROCs observed were: APRI = 0.793 ± 0.047, FIB-4 = 0.811 ± 0.045 and AST/ALT = 0.661 ± 0.055 (P = 0.054 for APRI vs. AST/ALT, and P = 0.014 for FIB-4 vs. AST/ALT). Considering classic cutoffs, the PPV and NPV for APRI and FIB-4 were, respectively, 77% and 92% and 83% and 81%. Thirteen (19%) patients were misdiagnosed by APRI and 16 (18%) by FIB-4. By restricting the indication of liver biopsy to patients with intermediate values, it could have been correctly avoided in 47% and 63% of the patients with APRI and FIB-4, respectively. CONCLUSION The models APRI and FIB-4 were superior to AST/ALT ratio in the diagnosis of significant fibrosis in chronic HCV infection. Even though the overall performance of APRI and FIB-4 was similar, a higher proportion of patients may be correctly classified by FIB-4.

Abstract
Anti-hepatitis C virus (HCV) antibody seropositivity is independently associated with poor prognosis in hemodialysis (HD) patients. However, anti-HCV antibody cannot distinguish between patients with active infection and those who have recovered from infection. We therefore aimed in this study to examine the association of HCV core antigen (HCVcAg) seropositivity with mortality in HD patients. We first measured serum HCVcAg using an immunoradiometric assay and anti-HCV antibody in 405 patients on regular HD, and followed them for 104 months. There were 82 patients (20.2%) who had been positive for anti-HCV antibodies; 57 (69.5%) of these were positive for HCVcAg. During the follow-up, 29 patients were excluded, so we tested the association of HCVcAg seropositivity with all-cause, cardiovascular (CV) and non-CV mortalities in 376 patients. A total of 209 patients (55.6%) had expired during the observational period, 92 out of them due to CV causes. After adjusting for comorbid parameters, HCVcAg was independently associated with overall mortality (HR 1.61, 95% CI 1.05–2.47, p < 0.05). HCV infection was significantly related to liver disease-related mortality. Past HCV infection also contributed to CV mortality (HR 2.63, 95% CI 1.27–5.45, p < 0.01). In contrast, anti-HCV antibody and HCVcAg seropositivities did not associate with infectious disease-related and cancer-related (expect for hepatocellular carcinoma) mortality. It follows from these findings that HCVcAg serology is associated with all-cause and CV mortality in HD patients.

Abstract
BACKGROUND/OBJECTIVES Circulating endothelial cells (CECs) are indicative of vascular injury and correlate with severity of vascular diseases. A pilot study showed that the ratio of CEC to platelet count (CEC/PC) was effective in predicting cirrhosis. Therefore, we evaluated CEC/PC in a larger cohort of patients, correlated it with cirrhosis, and compared its operating characteristics with previously described biomarker for cirrhosis, the AST/platelet ratio index (APRI). METHODS Fifty-three patients with cirrhosis, 20 matched healthy controls, and 9 patients with noncirrhotic liver disease were recruited. Peripheral blood sample was collected and analyzed to enumerate nucleated CEC CD146+, CD105+, CD45- using a commercial assay. RESULTS Median CEC counts were significantly higher in patients with cirrhosis (62 cells/4 mL, interquartile range [IQR]: 43.5-121) as compared with controls (31 cells/4 mL, IQR: 22.2-40). The CEC/PC was also significantly elevated in cirrhotics (0.69, IQR: 0.39-1.48) compared with controls (0.12, IQR: 0.09-0.20) and noncirrhotics (0.21, IQR: 0.08-0.43). Receiver operator characteristic (ROC) analysis revealed that CEC cutoff value of ≥37 cells/4 mL showed sensitivity of 81% and specificity of 75% for differentiating cirrhosis from controls (area under the curve [AUC]: 0.80; 95% confidence interval [CI] 0.67-0.91). The CEC/PC ratio cutoff value of ≥0.23 showed sensitivity of 91% and specificity of 82% (AUC: 0.92; 95% CI 0.83-0.99). The APRI cutoff value of ≥0.4 showed sensitivity of 94% and specificity of 85% for differentiating cirrhosis from control patients (AUC: 0.96; 95% CI 0.90-1.0). A product of CEC and APRI, termed CAPRI (CEC-APRI), effectively distinguished patients with cirrhosis from controls; with cutoff value of ≥12.7, showing higher sensitivity of 98% and specificity of 85% (AUC: 0.98; 95% CI 0.96-1.0). CONCLUSION The CEC/PC ratio is significantly elevated in patients with cirrhosis and demonstrates comparable operating characteristics to previously described APRI. Furthermore, CAPRI, compiled as product of CEC to APRI showed outstanding ability to distinguish patients with cirrhosis from controls, although larger studies are necessary for validation.

Abstract
Chronic kidney disease represents a global health problem. Chronic hepatitis C virus (HCV) infection is prevalent in patients with end stage renal disease (ESRD) on hemodialysis (HD) and in renal transplant recipients with significant impact on morbidity and mortality. Furthermore, HCV can cause various forms of glomerulopathy with the predominant type being cryglobulinemia associated membranoproliferative glomerulonephritis. Liver enzymes are traditionally used as markers of liver injury; however, there is wide variation in aminotransferase levels in patients with ESRD. Therefore, diagnosis of chronic hepatitis C (CHC) in patients with ESRD is based on HCV antibody testing and further confirmation with polymerase chain reaction testing. Current standard therapy for CHC is composed of pegylated interferon and ribavirin. However, this combination is challenging in patients with ESRD due to its tolerability. We describe in this review relevant issues in epidemiology, diagnosis and management of CHC in ESRD, HD and renal transplant recipients.

Abstract
Hepatitis C virus (HCV) infection is relatively common among patients with end-stage kidney disease (ESKD) on dialysis and kidney transplant recipients. HCV infection in hemodialysis patients is associated with an increased mortality due to liver cirrhosis and hepatocellular carcinoma. The severity of hepatitis C-related liver disease in kidney transplant candidates may predict patient and graft survival after transplant. Liver biopsy remains the gold standard in the assessment of liver fibrosis in this setting. Kidney transplantation, not haemodialysis, seems to be the best treatment for HCV+ve patients with ESKD. Transplantation of kidneys from HCV+ve donors restricted to HCV+ve recipients is safe and associated with a reduction in the waiting time. Simultaneous kidney/liver transplantation (SKL) should be considered for kidney transplant candidates with HCV-related decompensated cirrhosis. Treatment of HCV is more complex in hemodialysis patients, whereas treatment of HCV recurrence in SLK recipients appears effective and safe.

Abstract
A non-invasive diagnostic approach is crucial for the evaluation of severity of liver disease, treatment decisions, and assessing drug efficacy. This study evaluated plasma proteomic profiling via an N-terminal isotope tagging strategy coupled with liquid chromatography/Fourier transform ion cyclotron resonance mass spectrometry measurement to detect liver fibrosis staging. Pooled plasma from different liver fibrosis stages, which were assessed in advance by the current gold-standard of liver biopsy, was quantitatively analyzed. A total of 72 plasma proteins were found to be dysregulated during the fibrogenesis process, and this finding constituted a valuable candidate plasma biomarker bank for follow-up analysis. Validation results of fibronectin by Western blotting reconfirmed the mass-based data. Ingenuity Pathways Analysis showed four types of metabolic networks for the functional effect of liver fibrosis disease in chronic hepatitis B patients. Consequently, quantitative proteomics via the N-terminal acetyl isotope labeling technique provides an effective and useful tool for screening plasma candidate biomarkers for liver fibrosis. We quantitatively monitored the fibrogenesis process in CHB patients. We discovered many new valuable candidate biomarkers for the diagnosis of liver fibrosis and also partly identified the mechanism involved in liver fibrosis disease. These results provide a clearer understanding of liver fibrosis pathophysiology and will also hopefully lead to improvement of clinical diagnosis and treatment.

Abstract
Fibrosis prediction is an essential part of the assessment and management of patients with chronic liver disease. Blood-based biomarkers offer a number of advantages over the traditional standard of fibrosis assessment of liver biopsy, including safety, cost-savings and wide spread accessibility. Current biomarker algorithms include indirect surrogate measures of fibrosis, including aminotransaminases and platelet count, or direct measures of fibrinogenesis or fibrinolysis such as hyaluronic acid and tissue inhibitor of metalloproteinase-1. A number of algorithms have now been validated across a range of chronic liver disease including chronic viral hepatitis, alcoholic and non-alcoholic fatty liver disease. Furthermore, several models have been demonstrated to be dynamic to changes in fibrosis over time and are predictive of liver-related survival and overall survival to a greater degree than liver biopsy. Current limitations of biomarker models include a significant indeterminate range, and a predictive ability that is limited to only a few stages of fibrosis. Utilization of these biomarker models requires knowledge of patient co-morbidities which may produce false positive or negative results in a small proportion of individuals. Furthermore, knowledge of the underlying prevalence of fibrosis in the patient population is required for interpretation of the positive or negative predictive values of a test result. Novel proteins identified by proteomic technology and genetic polymorphisms from genome association studies offer the possibility for further refinement and individualization of biomarker fibrosis models in the future.

Abstract
Chronic Hepatitis C (HCV) infection is an important cause of morbidity and mortality in patients with end-stage renal disease. Renal transplantation confers a survival advantage in HCV-infected patients. Renal transplant candidates with serologic evidence of HCV infection should undergo a liver biopsy to assess for fibrosis and cirrhosis. Patients with Metavir fibrosis score ≤3 and compensated cirrhosis should be evaluated for interferon-based therapy. Achievement of sustained virological response (SVR) may reduce the risks for both posttransplantation hepatic and extrahepatic complications such as de novo or recurrent glomerulonephritis associated with HCV. Patients who cannot achieve SVR and have no live kidney donor may be considered for HCV-positive kidneys. Interferon should be avoided after kidney transplant except for treatment of life-threatening liver injury, such as fibrosing cholestatic hepatitis. Early detection, prevention, and treatment of complications due to chronic HCV infection may improve the outcomes of kidney transplant recipients with chronic HCV infection.

Abstract
BACKGROUND AND OBJECTIVES Although percutaneous liver biopsy (PLB) is the gold standard for staging hepatic fibrosis in hemodialysis patients with chronic hepatitis C (CHC) before renal transplantation or antiviral therapy, concerns exist about serious postbiopsy complications. Using transient elastography (TE, Fibroscan(®)) to predict the severity of hepatic fibrosis has not been prospectively evaluated in these patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A total of 284 hemodialysis patients with CHC were enrolled. TE and aspartate aminotransferase-to-platelet ratio index (APRI) were performed before PLB. The severity of hepatic fibrosis was staged by METAVIR scores ranging from F0 to F4. Receiver operating characteristic curves were used to assess the diagnostic accuracy of TE and APRI, taking PLB as the reference standard. RESULTS The areas under curves of TE were higher than those of APRI in predicting patients with significant hepatic fibrosis (≥F2) (0.96 versus 0.84, P<0.001), those with advanced hepatic fibrosis (≥F3) (0.98 versus 0.93, P=0.04), and those with cirrhosis (F4) (0.99 versus 0.92, P=0.13). Choosing optimized liver stiffness measurements of 5.3, 8.3, and 9.2 kPa had high sensitivity (93-100%) and specificity (88-99%), and 87, 97, and 93% of the patients with a fibrosis stage of ≥F2, ≥F3, and F4 were correctly diagnosed without PLB, respectively. CONCLUSIONS TE is superior to APRI in assessing the severity of hepatic fibrosis and can substantially decrease the need of staging PLB in hemodialysis patients with CHC.

Abstract
UNLABELLED The aspartate aminotransferase-to-platelet ratio index (APRI), a tool with limited expense and widespread availability, is a promising noninvasive alternative to liver biopsy for detecting hepatic fibrosis. The objective of this study was to update the 2007 meta-analysis to systematically assess the accuracy of APRI in predicting significant fibrosis, severe fibrosis, and cirrhosis stage in hepatitis C virus (HCV) monoinfected and HCV / human immunodeficiency virus (HIV) coinfected individuals. Studies comparing APRI versus biopsy in HCV patients were identified via a thorough literature search. Areas under summary receiver operating characteristic curves (AUROC), sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were used to examine the APRI accuracy for the diagnosis of significant fibrosis, severe fibrosis, and cirrhosis. Heterogeneity was explored using meta-regression. Twenty-one additional studies were eligible for the update and, in total, 40 studies were included in this review (n = 8,739). The summary AUROC of the APRI for the diagnosis of significant fibrosis, severe fibrosis, and cirrhosis were 0.77, 0.80, and 0.83, respectively. For significant fibrosis, an APRI threshold of 0.7 was 77% sensitive and 72% specific. For severe fibrosis, a threshold of 1.0 was 61% sensitive and 64% specific. For cirrhosis, a threshold of 1.0 was 76% sensitive and 72% specific. Moreover, we found that the APRI was less accurate for the identification of significant fibrosis, severe fibrosis, and cirrhosis in HIV/HCV coinfected patients. CONCLUSION Our large meta-analysis suggests that APRI can identify hepatitis C-related fibrosis with a moderate degree of accuracy. Application of this index may decrease the need for staging liver biopsy specimens among chronic hepatitis C patients.

Abstract
Hepatitis C virus (HCV) infection is a major health problem in patients with end-stage renal disease (ESRD). The incidence of acute HCV infection during maintenance dialysis is much higher than that in the general population because of the risk of nosocomial transmission. Following acute HCV infection, most patients develop chronic HCV infection, and a significant proportion develop chronic hepatitis, cirrhosis, and even hepatocellular carcinoma. Overall, chronic hepatitis C patients on hemodialysis bear an increased risk of liver-related morbidity and mortality, either during dialysis or after renal transplantation. Interferon (IFN) therapy is modestly effective for the treatment of HCV infection in ESRD patients. Conventional or pegylated IFN monotherapy has been used to treat acute hepatitis C in ESRD patients with excellent safety and efficacy. Regarding chronic hepatitis C, approximately one-third of patients can achieve a sustained virological response (SVR) after conventional or pegylated IFN monotherapy. The combination of low-dose ribavirin and conventional or pegylated IFN has further improved the SVR rate in treatment-naïve or retreated ESRD patients in clinical trials. Similar to the treatment of patients with normal renal function, baseline and on-treatment HCV virokinetics are useful to guide optimized therapy in ESRD patients. Of particular note, IFN-based therapy is not recommended at the post-renal transplantation stage because of the low SVR rate and risk of acute graft rejection. In conclusion, ESRD patients with HCV infection should be encouraged to receive antiviral therapy, and those who achieve an SVR usually have long-term, durable, virological, biochemical, and histological responses.

Abstract
Hepatitis C virus (HCV) is the major cause of liver disease in haemophilia. Few data exist on the proportion with liver fibrosis in this group after long-term HCV and HIV co-infection. We conducted a cross-sectional multi-centre study to determine the impact of HIV on the prevalence and risk factors for fibrosis in haemophilic men with chronic hepatitis C. Biopsies were independently scored by Ishak, Metavir and Knodell systems. Variables were tested for associations with fibrosis using logistic regression and receiver operating curves (ROC). Of 220 biopsied HCV(+) men, 23.6% had Metavir ≥ F3 fibrosis, with higher mean Metavir fibrosis scores among HIV/HCV co-infected than HCV mono-infected, 1.6 vs. 1.3 (P = 0.044). Variables significantly associated with fibrosis included AST, ALT, APRI score (AST/ULN × 100/platelet × 10(9) /L), alpha-fetoprotein (all P < 0.0001), platelets (P = 0.0003) and ferritin (P = 0.0008). In multiple logistic regression of serum markers, alpha-fetoprotein, APRI and ALT were significantly associated with ≥ F3 fibrosis [AUROC = 0.77 (95% CI 0.69, 0.86)]. Alpha-fetoprotein, APRI and ferritin were significant in HIV(-) [AUROC = 0.82 (95% CI 0.72, 0.92)], and alpha-fetoprotein and platelets in HIV(+) [AUROC = 0.77 (95% CI 0.65, 0.88]. In a multivariable model of demographic and clinical variables, transformed (natural logarithm) of alpha-fetoprotein (P = 0.0003), age (P = 0.006) and HCV treatment (P = 0.027) were significantly associated with fibrosis. Nearly one-fourth of haemophilic men have Metavir ≥ 3 fibrosis. The odds for developing fibrosis are increased in those with elevated alpha-fetoprotein, increasing age and past HCV treatment.

Abstract
HCV infection is highly prevalent among kidney transplant (KT) recipients. The natural history and management of these patients are controversial. We sought to assess the diagnostic value of noninvasive markers of liver fibrosis in KT HCV-infected patients. This cross-sectional study included 102 KT individuals with positive HCV-RNA. Bivariate and multivariate analyses were used to identify variables associated with significant fibrosis (METAVIR > or = F2). Significant fibrosis was observed in 20 patients (20%). Time after transplantation, AST level, and platelet count were identified as independent predictors of significant fibrosis. Based on the regression model, a simplified index was devised. The AUROC for the TX-3 model was 0.867 +/- 0.081 (0.909, when adjusted by DANA). Values < or =4.0 of TX-3 showed a NPV of 97% and scores >9.6 exhibited a PPV of 71%. If biopsy indication was restricted to scores in the intermediate range of TX-3, this could have been correctly avoided in 68% of cases. The APRI score provided a correct diagnosis in only 47 individuals (46%) and exhibited lower diagnostic indices for both cutoffs, as compared to the TX-3 index. Comparison of AUROCs showed a trend towards superior diagnostic accuracy for TX-3 over APRI, although the difference between AUROCs did not reach statistical significance (0.867 +/- 0.053 vs 0.762 +/- 0.066, respectively, P = 0.064). In conclusion, significant liver fibrosis can be reliably predicted in KT HCV-infected subjects by simple and widely available parameters. If additional studies confirm our results, this model might obviate the requirement for a liver biopsy in a significant proportion of those patients.

Abstract
An intensive research effort in the field of non-invasive evaluation of liver fibrosis has recently permitted the description and validation of several serum markers of fibrosis, mainly in chronic hepatitis C patients. In addition to the commonly used tests such as FibroTest or FibroMeters, other either indirect (aspartate aminotransferase, prothrombin time, platelets) or direct (PIIINP, hyaluronic acid, metalloproteinases) markers, usually used in combination, have been evaluated. Simple scores such as APRI or FIB-4 have also been widely studied and have revealed interesting, albeit non-comprehensive, data on liver fibrosis, especially in terms of significant, extensive fibrosis or cirrhosis. These simple scores may be proposed as a first-line investigation, bearing in mind their limitations and comparing them with more accurate methods for evaluating liver fibrosis if necessary. Other scores, including direct serum markers, which can be difficult to assess, have given disappointing results that, in general, were either similar to, or only slightly better than, the results of the simpler tests. Further studies are needed to identify new markers that are more accurate and, above all, able to predict the outcome of liver fibrosis.

Abstract
GOAL To investigate the performance of liver stiffness measurement (LSM) in combination with available noninvasive markers in hepatitis B virus-related chronic liver disease. BACKGROUND Few noninvasive methods are available for predicting liver cirrhosis in chronic hepatitis B (CHB). STUDY Between January 2006 and June 2007, we studied 130 consecutive treatment-naive CHB patients who underwent liver biopsy (LB) and LSM. The aspartate to alanine aminotransferase ratio, age-platelet index (API), aspartate aminotransferase to platelet ratio index (APRI), LSM, and their combinations were compared with liver histology. RESULTS The API, APRI, and LSM, but not the aspartate to alanine aminotransferase ratio, correlated significantly with liver cirrhosis (all P<0.001). The diagnostic accuracy of LSM and API exceed that of the other diagnostic methods for predicting liver cirrhosis (area under the receiver operating characteristic curve=0.840 and 0.818). When LSM was combined with API and APRI, the diagnostic accuracy was improved markedly (area under the receiver operating characteristic curve =0.871, and 0.846). When both LSM and API results were in agreement, LB confirmed them in 89.1% (41/46) of cases for liver cirrhosis. LB could have been avoided in 41 (31.5%) of the 130 patients who were examined for the potential diagnosis of liver cirrhosis. CONCLUSIONS The combination of LSM and API can avoid unnecessary invasive LB procedures in CHB patients.
