RESUMO

Evaluating liver fibrosis is crucial for disease severity assessment, treatment decisions, and hepatocarcinogenic risk prediction among patients with chronic hepatitis C. In this retrospective multicenter study, we aimed to construct a novel model formula to predict cirrhosis. A total of 749 patients were randomly allocated to training and validation sets at a ratio of 2:1. Liver stiffness measurement (LSM) was made via transient elastography using FibroScan. Patients with LSM ≥12.5 kPa were regarded as having cirrhosis. The best model formula for predicting cirrhosis was constructed based on factors significantly and independently associated with LSM (≥12.5 kPa) using multivariate regression analysis. Among the 749 patients, 198 (26.4%) had LSM ≥12.5 kPa. In the training set, multivariate analysis identified logarithm natural (ln) type IV collagen 7S, ln hyaluronic acid, and ln Wisteria floribunda agglutinin positive Mac-2-binding protein (WFA+-Mac-2 BP) as the factors that were significantly and independently associated with LSM ≥12.5 kPa. Thus, the formula was constructed as follows: score = -6.154 + 1.166 × ln type IV collagen 7S + 0.526 × ln hyaluronic acid + 1.069 × WFA+-Mac-2 BP. The novel formula yielded the highest area under the curve (0.882; optimal cutoff, -0.381), specificity (81.5%), positive predictive values (62.6%), and predictive accuracy (81.6%) for predicting LSM ≥12.5 kPa among fibrosis markers and indices. These results were almost similar to those in the validated set, indicating the reproducibility and validity of the novel formula. The novel formula scores were significantly, strongly, and positively correlated with LSM values in both the training and validation data sets (correlation coefficient, 0.721 and 0.762; p = 2.67 × 10-81 and 1.88 × 10-48, respectively). In conclusion, the novel formula was highly capable of diagnosing cirrhosis in patients with chronic hepatitis C and exhibited better diagnostic performance compared to conventional fibrosis markers and indices.

RESUMO

BACKGROUND: Colonization and marginalization have affected the risk for and experience of hepatitis C virus (HCV) infection for First Nations people in Canada. In partnership with the Ontario First Nations HIV/AIDS Education Circle, we estimated the publicly borne health care costs associated with HCV infection among Status First Nations people in Ontario. METHODS: In this retrospective matched cohort study, we used linked health administrative databases to identify Status First Nations people in Ontario who tested positive for HCV antibodies or RNA between 2004 and 2014, and Status First Nations people who had no HCV testing records or only a negative test result (control group, matched 2:1 to case participants). We estimated total and net costs (difference between case and control participants) for 4 phases of care: prediagnosis (6 mo before HCV infection diagnosis), initial (after diagnosis), late (liver disease) and terminal (6 mo before death), until death or Dec. 31, 2017, whichever occurred first. We stratified costs by sex and residence within or outside of First Nations communities. All costs were measured in 2018 Canadian dollars. RESULTS: From 2004 to 2014, 2197 people were diagnosed with HCV infection. The mean net total costs per 30 days of HCV infection were $348 (95% confidence interval [CI] $277 to $427) for the prediagnosis phase, $377 (95% CI $288 to $470) for the initial phase, $1768 (95% CI $1153 to $2427) for the late phase and $893 (95% CI -$1114 to $3149) for the terminal phase. After diagnosis of HCV infection, net costs varied considerably among those who resided within compared to outside of First Nations communities. Net costs were higher for females than for males except in the terminal phase. INTERPRETATION: The costs per 30 days of HCV infection among Status First Nations people in Ontario increased substantially with progression to advanced liver disease and finally to death. These estimates will allow for planning and evaluation of provincial and territorial population-specific hepatitis C control efforts.

RESUMO

BACKGROUND: Changes in renal function in chronic hepatitis C (CHC) patients receiving direct-acting antivirals (DAAs) are controversial. The evolution of neutrophil gelatinase-associated lipocalin (NGAL) in these patients remains unclear. METHODS: A total of 232 CHC patients receiving DAA at Dalin Tzu Chi Hospital from May 2016 to February 2019, were enrolled in this retrospective study. Grade 2/3 renal function deterioration, defined as a decrease in eGFR between 10% and 50% from baseline (BL) to 12 weeks after the end of treatment (P12), was investigated for its association with BL characteristics. The changes in renal function and NGAL levels were also analyzed at the SOF-base or nonSOF-base DAA. RESULTS: Sixty-two patients (26.7%) had grade 2/3 renal function deterioration at P12 after DAA therapy. Univariate analysis showed that it was associated with age (P = 0.038). Multivariate analysis indicated that age (OR = 1.033, 95% CI: 1.004-1.064, P = 0.027), sex (male; OR = 2.039, 95% CI: 1.093-3.804, P = 0.025), ACEI/ARB use (OR = 2.493, 95% CI: 1.016-6.119, P = 0.046), and BL NGAL (OR = 1.033, 95% CI: 1.001-1.067, P = 0.046) positively correlated with grade 2/3 renal function deterioration. Furthermore, eGFR was decreased (P = 0.009) and NGAL was increased (P = 0.004) from BL to P12 in CHC patients receiving SOF-based DAA. CONCLUSIONS: Of the CHC patients receiving DAA therapy, 26.7% had grade 2/3 renal function deterioration at P12, and it was associated with older age, gender being male, ACEI/ARB use, and higher BL NGAL levels. In addition, NGAL might be a biomarker of nephrotoxicity at P12 in patients receiving SOF-based DAA.

RESUMO

We aimed to evaluate the correlation between vascular endothelial growth factor (VEGF) and long-term occurrence of hepatocellular carcinoma after HCV treatment with direct-acting antivirals (DAAs) and the HCC stage. Two groups with HCV-related liver cirrhosis and HCC were included: group 1, HCC following DAAs; group 2, HCC did not receive DAAs. The serum level of VEGF and HCC staging was evaluated. The duration between DAAs and HCC was 21.81 ± 11.66 months. Portal vein thrombosis (PVT) was observed more in group 1 (31%). VEGF was relatively elevated in group 1 compared to group 2. HCC patients after DAAs, showed elevated VEGF with frequent PVT.

RESUMO

Introduction: Oxidative stress underlies the pathophysiology of various etiologies of chronic liver disease and contributes to the development of hepatocarcinogenesis.Areas covered: This review focuses on the impact of oxidative stress in various etiologies of chronic liver disease such as alcoholic liver disease (ALD), nonalcoholic steatohepatitis (NASH), hepatitis B virus (HBV), and hepatitis C virus (HCV) infection. The efficacy of antioxidants in laboratory, animal, and clinical studies in chronic liver disease is also reviewed.Expert opinion: Currently, there are limited targeted pharmacotherapeutics for NASH and no pharmacotherapeutics for ALD and antioxidant supplementation may be useful in these conditions to improve liver function and reverse fibrosis. Antioxidants may also be used in patients with HBV or HCV infection to supplement antiviral therapies. Specific genotypes of antioxidant and prooxidant genes render patients more susceptible to liver cirrhosis and hepatocellular carcinoma while other individual characteristics like age, genotype, and metabolomic profiling can influence the efficacy of antioxidants on CLD. More research needs to be done to establish the safety, efficacy, and dosage of antioxidants and to establish the ideal patient profile that will benefit the most from antioxidant treatment.

RESUMO

BACKGROUND: In patients with chronic hepatitis C (CHC), a negative impact of associated malnutrition on both morbidity and mortality was reported. We aimed to elucidate the efficacy of serum liver fibrosis markers (fibronectin (FN), hydroxyproline (Hyp), and hyaluronic acid (HA)) and their respective indices (HA index, Hyp index, and FN index) and vitamin D status in predicting malnutrition associated with liver fibrosis in CHC patients and to investigate their association with the value of current clinical malnutrition assessment tools subjective global assessment (SGA), handgrip strength (HGS), and muscle mass scores (SGA, BMI, MAMC, and HGS). MATERIALS AND METHODS: A cross-sectional study was conducted on 80 patients aged 40-60 years with proven viremia, HCV antibodies, HCV-RNA positivity, genotype determinations, and established chronic hepatitis C virus for more than 6 years and 80 control subjects. SGA, HGS, and muscle mass score (MAMC) were estimated in both patients and control subjects. Based on SGA scores, CHC patients were classified into three groups: well nourished (n = 12; SGA-A); mild or moderately malnourished (n = 25; SGA-B); and severely malnourished (n = 43; SGA-C). Liver fibrosis markers, inflammatory indicator α-Fetoprotein (AFP), tumor necrosis factor-alpha (TNF-α), 25-hydroxyvitamin D, and PTH were estimated using immunoassay techniques. RESULTS: CHC patients with moderate and severe malnutrition SGA scores showed a significant decline in the levels of vitamin D, increased PTH, and lower values of HGS and muscle mass indices compared to well-nourished patients and control subjects. In addition, malnutrition, vitamin D deficiency, and lower values of HGS, MAC, TSF, and MAMC showed significant correlation with liver severity among CHC patients. Liver fibrosis markers Hyp, HA, FN, APRI, HypI, HAI, and FNI as noninvasive biomarkers showed significant correlation with both severity of liver diseases and associated malnutrition, especially in cirrhotic HCV patients (F4) compared to those with significant fibrosis (F2-F3). CONCLUSION: The results showed that deficiency in vitamin D levels, HGS, SGA, and muscle mass scores (MAC, MAMC, or TSF) could be used as markers of liver pathogenicity in patients with CHC. In addition, the study concluded that noninvasive biomarkers Hyp, HA, FN, APRI, HypI, HAI, and FNI separately or in association with vitamin D status, HGS, SGA, and muscle mass scores (MAC, MAMC, or TSF) were significantly associated with an incidence of malnutrition between ~70.5% and 89.6% of CHC patients with significant fibrosis and cirrhosis.

RESUMO

BACKGROUND: The World Health Organization (WHO) set out to eliminate hepatitis C virus (HCV) infection by 2030, a goal Taiwan might achieve before 2025. Using effective direct antiviral agents (DAAs) against chronic hepatitis C (CHC) in Taiwan, the treatment of CHC has been initiated in rural areas. Here, we aimed to elucidate the clinical and virological characteristics of HCV infection, and the treatment efficacy of DAAs in patients from Pingtung county in southern Taiwan. METHODS: A total of 152 chronic hepatitis patients treated with DAAs were consecutively enrolled. Baseline characteristics and therapeutic efficacy were evaluated. RESULTS: HCV genotype 2 was the most common viral genotype (39.5%), followed by 1b (36.8%), 6 (10.5%), and 1a (9.2%). The sustained virological response (SVR) rate was 98.7%. Hakka patients accounted for 22.4% of the study cohort, of which 14.7% had HCV genotype 6. There were no differences in clinical characteristics between Hakka and non-Hakka patients. Patients with HCV genotype 6 were younger in age (OR/CI: 0.95/0.91-1.00, p = 0.04) and composed of more people who inject drugs (PWID) (OR/CI: 17.6/3.6-85.5, p <0.001), when compared with other patients. CONCLUSION: We demonstrated that DAA therapy can achieve a 98.7% SVR rate among CHC patients in Pingtung county of southern Taiwan, with a relative higher prevalence of genotype 6. The most important factor attributed to genotype 6 infection was PWID.

RESUMO

The HepQuant SHUNT test quantifies liver function and blood flow using systemic and portal clearances of cholate. The test can identify the risk of well-compensated patients to develop complications of cirrhosis. To confirm the reliability of a single HepQuant SHUNT test we defined its within-individual reproducibility. Healthy subjects (n = 16), 16 with nonalcoholic steatohepatitis (NASH), and 16 with chronic hepatitis C virus (HCV) underwent 3 HepQuant SHUNT tests on 3 separate days within 30 days. The test involves simultaneous administration of 20 mg 13C-cholate IV and 40 mg d4-cholate PO, and subsequent collection of 3 mL blood samples at 5, 20, 45, 60, and 90 minutes. Clearances are expressed as systemic and portal hepatic filtration rate. Portal-systemic shunting (SHUNT), a disease severity index (DSI), and an estimate of DSI (STAT) are calculated from the clearances. Reproducibility was determined by the intraclass correlation coefficient (ICC > 0.70) and Bland-Altman analysis. Equal numbers of NASH and HCV patients had either early (F0-F2) or advanced (F3/F4) stages of fibrosis. All F3/F4 subjects were clinically compensated. The intraclass correlation coefficient (ICC) for DSI was 0.94 (0.90-0.96 95% confidence interval) indicating excellent reproducibility. The other test parameters had ICCs ranging from 0.74 (SHUNT) to 0.90 (STAT). In Bland-Altman analysis, the mean of differences between measurements of DSI was 0.13 with standard deviation 2.12. The excellent reproducibility of the HepQuant SHUNT test, particularly DSI, supports the use this minimally invasive, blood-based test as a reliable test of liver function and physiology.

RESUMO

BACKGROUND: Reactivation of hepatitis B virus (HBV) infection in patients treated for chronic hepatitis C (HCV) with direct-acting antiviral agents has emerged recently as an important safety issue; however, it has not been adequately studied in pediatric age groups. We aimed to evaluate this risk in adolescent patients infected with chronic HCV and positive for HBsAg and HBcAbs. PATIENTS AND METHODS: One hundred and fifteen adolescent patients from 12 to 17 years of age, infected with chronic HCV and positive for HBcAbs with or without HBsAg were included in this study. All patients were treated with 1 tablet daily of the fixed-dose combination sofosbuvir/ledipasvir for 12 weeks. Patients were closely monitored throughout the study for virus load, liver functions, and other safety and efficacy outcome measures. RESULTS: The sustained virologic response 12 (SVR12) rates were 96.7% (95% confidence interval: 88.6-99.1%) in HBsAg positive group and 98.2% (95% confidence interval: 90.4-99.7%) in HBsAg negative with HBcAbs positive group. Throughout the treatment period and the 12 weeks follow-up after treatment, there has been no single case in both HBsAg negative or positive that showed any manifestation of reactivation of hepatitis B, detected levels of HBV-DNA, or deterioration of liver functions. CONCLUSION: No HBV reactivation was observed in adolescents treated for chronic HCV with direct-acting antiviral agents in our study, in both HBsAg positive or occult hepatitis B. Although results are reassuring, we still recommend close monitoring of liver functions to not miss even rare cases of such a potentially serious condition.

RESUMO

BACKGROUND: Loss of skeletal muscle mass is very common in chronic liver diseases and affects 30.0-70.0% of the patients with cirrhosis. Given the relevance of muscle wasting in hepatic diseases, a practical screening tool for earlier detection of skeletal muscle mass loss is of utmost significance. AIMS: To develop and validate a simple anthropometric prediction equation for fat-free mass estimation by using Bioelectrical Impedance Analysis (BIA) as a reference method in patients with chronic hepatitis C (CHC). METHODS: We prospectively, included 209 CHC patients, randomly allocated into two groups, 158 patients in a development model (derivation sample) and 51 patients in a validation group (validation sample). Predictive equations were developed using backward stepwise multiple regression and the most adequate and simplest derived predictive equation was further explored for agreement and bias in the validation sample. The accuracy of the predictive equation was evaluated using the coefficient of determination (R2). RESULTS: The predictive equation with an optimal R2 was Fat-Free Mass (Kg) = Sex × 0.17 + Height (m) × 16.83 + Weight (Kg) × 0.62 + Waist Circumference (cm) × (-0.15) + Weight (Kg) × Sex × (-0.30) + Sex × Waist Circumference (cm) × 0.14-6.23; where sex = 1 for female and 0 for male. R2 = 0.93, standard error of the estimate = 2.6 Kg and coefficient of variation = 20.0%, p < 0.001. CONCLUSIONS: Our developed and cross-validated anthropometric prediction equation for fat-free mass estimation by using BIA attained a high coefficient of determination, a low standard error of the estimate, and lowermost coefficient of variation. This study indicates that predictive equations may be reliable and useful alternative methods for clinical evaluation of fat-free mass in patients with CHC.

RESUMO

BACKGROUND AND AIM: Since the advent of direct-acting antiviral (DAA) therapy, the total eradication of hepatitis C virus has been achievable with the recovery of hepatic reserve after achievement of sustained virologic response (SVR). Hence, here, we examined the factors affecting the recovery of hepatic reserve. METHODS: We followed up 403 patients (male: 164, female: 239; genotype 1: 299, genotype 2: 104; median age: 69 years) for at least 3 years after they achieved SVR to DAA therapy. Of these patients, 75 (18.6%) had a history of hepatocellular carcinoma (HCC). Biochemical tests were periodically performed, and the hepatic reserve was evaluated based on the albumin-bilirubin grade. We examined background factors such as age, biochemical test results, HCC occurrence and portosystemic shunt by computed tomography. RESULTS: At the start of treatment, the albumin-bilirubin grades were grades 1, 2, and 3 in 241, 157, and 5 patients, respectively, and 3 years later, 117 of 162 (72%) patients with grade 2 or 3 improved to grade 1. Multivariate analysis identified the HCC occurrence after achievement of SVR (hazard ratio [HR]: 3.08, P < 0.0138), male sex (HR: 3.45, P = 0.0143), hemoglobin level of <11.5 g/dL (HR: 4.19, P = 0.0157), the presence of a portosystemic shunt (HR: 3.07, P = 0.0349), and alanine aminotransferase levels <45 U/L (HR: 2.67, P = 0.0425) as factors inhibiting improvement to grade 1. However, old age was not an inhibitory factor. CONCLUSION: Our results demonstrate that hepatic reserve could be improved even in elderly patients over a long course of time.

RESUMO

BACKGROUND AND AIM: Globally, China has the highest chronic hepatitis C (CHC) burden, but its real-world direct-acting antiviral (DAA) data are limited. Our aim is to investigate the real-world outcome of China Food and Drug Administration-approved DAA therapies across mainland China including those with genotype (GT) 3. METHODS: The REAL-C is a multinational real-world interferon-free DAA-treated CHC registry of several mainland China and other Asian centers. We evaluated the sustained virological response rate 12 weeks after end of treatment (SVR12), adverse events, and treatment effect on liver function and fibrosis (fibrosis-4 index). RESULTS: We analyzed 859 DAA-treated CHC patients (6/1/2017-5/30/2019) from 12 mainland China centers (three municipalities and nine provinces): median age 52, 49.9% male, 33.1% cirrhosis, 95% treatment naïve, and 2.5% HBsAg+ . The most common GT was GT1b (523, 62.2%), followed by GT2a (156, 18.5%), GT3b (74, 8.8%), GT3a (41, 4.9%), and GT6 (37, 4.4%). SVR12 rates were 98.0% overall (95% confidence interval 96.9-98.8%), 98.1% for GT1b, 96.8% GT2a, 100% GT3a, 97.3% GT3b, and 100% GT6. Baseline cirrhosis and male sex but not prior treatment history, renal dysfunction, age, and GTs were associated with SVR12. For both cirrhotic and non-cirrhotic patients, there were significant improvement in liver function tests, alpha fetoprotein, and fibrosis-4 index with SVR12. Serious adverse events were rare (1.1%) with only nine patients discontinuing therapy prematurely and anemia being the most common adverse event (13.1%, mostly with ribavirin). CONCLUSIONS: In real-world Chinese patients with diverse GTs, Chinese Food and Drug Administration-approved interferon-free DAAs were well tolerated, provided high cure rates (98.0% overall) including GT3a/3b, and led to improvement of liver function.

RESUMO

Genetic variation of related genes in Vitamin D (VD) metabolic pathway played an important role in antiviral immune response and chronic hepatitis C virus (HCV) infection. Retinoid X receptor (RXR) is one of the key genes in the metabolism pathway of VD. This study aims to investigate the effect of single nucleotide polymorphisms (SNPs) in RXR on the outcomes of HCV infection. Three SNPs (RXRɑ-rs4842194, rs1045570 and RXRß-rs2076310) were genotyped using Sequenom MassARRAY platform in 515 spontaneous clearance subjects, 830 persistent infection subjects, and 1062 uninfected subjects. Multivariate stepwise regression analyss was used to identify the prediction factors for HCV infection outcomes. The USCS Brower and RNAfold web serves were performed to further explore the potential biological functions of positive SNPs. The results of logistic regression analysis after adjusting for age, gender and types of high-risk population showed that subjects with RXRß rs2076310-T (recessive model: adjusted OR = 1.598, 95%CI = 1.126-2.267, P = 0.009; additive model: adjusted OR = 1.196, 95%CI = 1.011-1.416, P = 0.037) had a significantly increased possibility of HCV infection chronicity. Rs2076310, age, types of high-risk population and aspartate aminotransferase were independent predictors of chronic HCV infection (P < 0.05). And the area under the receiver operating characteristic curve of combined effects of these factors was 0.679. Bioinformatics analysis indicated that rs2076310 could affect the gene expression level by affecting the transcriptional regulatory activity of the corresponding gene region. These findings indicated that genetic variation of RXRß was associated with the risk of HCV infection chronicity among a high-risk Chinese population.

RESUMO

BACKGROUND/AIM: Evaluation of liver fibrosis in chronic hepatitis C patients (CHC) provides a high value, not only for the diagnosis of the disease, but also for the therapeutic decision. The aim of the current study is the construction of simple non-invasive and more accurate score for liver fibrosis staging in CHC patients and estimating its performance against three published non-invasive indexes. MATERIAL AND METHODS: CHC patients were divided into two groups: an estimated group (n = 75) and validated group (n = 50). Liver fibrosis was tested in biopsies by Metavair score system. Fas/CD95, hepatocyte growth factor (HGF) and endostatin were assayed by enzyme linked immunosorbent assay (ELISA). Statistical analysis was performed by stepwise linear discriminate analysis and area under-receiver operating curves (AUCs). RESULTS: The multivariate discriminate analysis (MDA) selects a function based on absolute values of five biochemical markers; FHEPA (Fas/CD95, HGF, Endostatin, Platelets&Albumin)-Test score = 1.2 × Fas/CD95 (ng/mL) + 0.006 × HGF (pg/mL) + 0.03 × Endostatin (ng/mL) - 0.007 × platelets count(109/L)-3.6 × Albumin (g/dL) - 8.6.FHEPA-Test producesAUCs 0.99, 0.877 and 0.847 to discriminate patients with significant fibrosis (F2-F4), advanced fibrosis (F3-F4) and cirrhosis (F4), respectively. CONCLUSION: FHEPA-Test is considered a novel non-invasive test which could be applied in assessment of liver fibrosis in HCV infected patients. Our novel score was more efficient than Immune Fibrosis Index, Fibrosis Index and FibroQ and thus it could be more applicable, feasible & economic for Egyptian HCV patients. Our Novel Scoring system could be globalized to other populations to confirm its advantageous use in early diagnosis of liver fibrosis.

RESUMO

INTRODUCTION: Interferon (IFN)-free regimens for the treatment of chronic hepatitis C have shown high rates of sustained virological response (SVR) and improved patient-reported outcomes (PROs). The aim of this study was to evaluate the health-related quality of life (HRQoL) and fatigue of patients with chronic hepatitis C (HCV) treated with IFN-free direct-acting antiviral (DAA) agents that achieved SVR following treatment and identify the predictive factors related to HRQoL. METHODS: Prospective cohort study that included patients with HCV treated with DAA who obtained an SVR. The patients answered three self-reported questionnaires (PROs): Short Form 36 (SF-36), the Chronic Liver Diseases Questionnaire (CLDQ), and the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaire at baseline, weeks 6 and 12 of treatment, and at 12 weeks after therapy. Patients were treated with DAA with or without ribavirin (RBV). The PRO scores were compared using analysis of variance (ANOVA). A comparison of PROs and serum hemoglobin levels was performed between the group that used ribavirin and the one that did not use ribavirin using the t student test. Predictive factors were calculated using a multiple linear regression model. RESULTS: Among the 113 patients selected, 105 presented an SVR and were included in the study, in which, 54% men, 80% genotype 1, 44% cirrhosis and 46% with RBV. At 12 weeks after the end of treatment, there was a significant improvement in the scores of the patient self-reports (PROs) when compared with baseline for the CLDQ (+10.52%, p<0.001), SF-36-Physical Summary (+19%, p<0.001), and FACIT (+17.34%, p<0.001). Patients who used RBV had worse PROs and serum hemoglobin levels compared to the group that did not use RBV (p<0,05). As predictors of worsening of the PROs we had the presence of diabetes mellitus, liver cirrhosis and HIV co-infected. CONCLUSION: Patients treated with IFN free regimens presents significant improvement in PROs. The presence of diabetes mellitus, cirrhosis, and HIV co-infected has a negative effect on HRQoL before, during and after treatment of hepatitis C. The addition of ribavirin to the antiviral regimens used compromises the HRQoL indexes during antiviral therapy.

RESUMO

BACKGROUND & AIMS: Complications of cirrhosis are the main cause of hospital admissions in liver units. In areas where HCV is prevalent, most of these admissions are attributable to HCV-related cirrhosis (HCV-cirrhosis). This study assessed the impact of direct-acting antivirals (DAA) in the profile of patients with liver disease admitted to a referral liver unit from a university hospital. METHODS: We registered hospital admissions resulting from cirrhosis to the Liver Unit of the Hospital Clinic of Barcelona, from 2011 to 2014 (pre-DAA period) and from 2015 to 2019 (post-DAA period). RESULTS: From a total of 14,865 hospital admissions, 10,053 resulted from cirrhosis (corresponding to 6,272 patients). The number and proportion of hospital admissions because of HCV-cirrhosis remained stable during the period 2011-2014 (525 per year, 48.8% of the total), but decreased progressively after 2015 (p <0.001), reaching <300 (27.1%) admissions in 2019. Similarly, HCV-cirrhosis accounted for 3,885 inpatient days per year (44.9%) during the pre-DAA period and decreased steadily after 2015 (p >0.001), reaching only 1,909 inpatient days (22%) in 2019. The figures for intensive care unit admissions followed a similar pattern. By means of a slope analysis (binomial regression model), we predicted that HCV-cirrhosis hospital admissions will be residual by 2025 (2.3%, 95% CI 0-10.9%). By contrast, we observed a significant increase in hospital admissions because of metabolic-associated fatty liver disease (5-fold) and autoimmune hepatitis (4-fold) during the study period. CONCLUSIONS: In summary, our data showed a profound reduction in HCV-cirrhosis hospitalisation burden since 2015, coincident with the wide use of DAAs in Spain. Our predictions suggest that, by 2025, HCV-cirrhosis will be a marginal cause of hospital admissions for patients with liver disease. LAY SUMMARY: Over the past few years, the wide use of antiviral drugs that cure HCV has had a significant effect on patients being admitted to hospital. Most patients with HCV and cirrhosis are treated (and often cured) in the community and, thus, the number of hospital admissions because of severe forms of HCV has decreased drastically. HCV is no longer the first cause of admission into liver units and, in only a few years from now, it is likely to be only a residual cause of hospitalisation.

RESUMO

The widespread adaptation of a new generation of direct-acting antiviral agents (DAAs) unveils a superlative effect in the eradication of the hepatitis C virus (HCV). However, this therapy has been reported to exhibit vigorous side effects that pose a risk in fleet recovery. This study was conducted to investigate the efficacy of DAAs: sofosbuvir (SOF) and ribavirin (RBV), along with black cumin (BLC) and ascorbate (ASC), as adjuvants on hematological parameters; oxidative stress markers such as total antioxidant status (TAS), superoxide dismutase (SOD), reduced (GSH) and oxidized (GSSG) glutathione (GSH), gamma-glutamyl transferase (GGT), and malondialdehyde (MDA); liver function markers such as aspartate transaminase (AST), alanine aminotransferase (ALT), bilirubin, and alkaline phosphatase (ALP); and viral load with determined genotypes. HCV-infected patients (n = 30) were randomly divided into two equal groups: control group (n = 15) and treatment group (n = 15). The control group was subjected only to SOF and RBV (400 mg each/day). Synergistically, the treatment group was administered with adjuvant therapy of BLC (250 mg/day) and ASC (1000 mg/day) along with DAAs (400 mg each/day) for 8 weeks. All selected patients were subjected to sampling at pre- and posttreatment stages for the assessment of defined parameters. The data revealed that the BLC/ASC adjuvant therapy boosted the efficacy of DAAs by reducing the elevated levels of liver markers such as AST, ALT, ALP, and bilirubin in the treatment group compared with those in the control group (P > 0.05). The adjuvant therapy synchronously showed an ameliorating effect on hematological parameters. The SOF/RBV with adjuvant therapy also demonstrated an increasing effect in the activity of SOD, TAS, and GSH and a decreasing effect for GSSG, GGT, and malondialdehyde (MDA; P > 0.05) followed by curtailing a RT-PCR-quantified viral load. Our findings provide evidence that systemic administration of BLC/ASC efficiently alleviates hematological, serological, and antioxidant markers as well as the viral load in hepatitis C patients. This highlights a potentially novel role of BLC and ASC in palliating hepatitis C.

RESUMO

Owing to the rapid development and wide clinical application of direct acting antiviral (DAA) drugs in the treatment of hepatitis C virus (HCV) infection, the era of interferon-based therapy has almost come to an end. Cumulative studies show that DAA therapy renders high cure efficiency (>90%) and good safety profile, and may even bring some unexpected benefits to the patients. However, some issues of concern arise, one of which is the resistance mutation of HCV genome leading to failure of treatment. With the aim of providing some meaningful references for the treatment of chronic hepatitis C (CHC), this article summarizes the research progress on benefits of DAA accompanied by viral clearance in the treatment of chronic hepatitis and the drug resistance.

RESUMO

BACKGROUND: Serum albumin level improves in patients with chronic hepatitis C virus (HCV) infection who achieve sustained virologic response (SVR) with antiviral therapy. However, it remains controversial whether liver volume increases along with SVR. METHODS: Patients with chronic HCV infection with a history of hepatocellular carcinoma (HCC) who achieved SVR with anti-HCV treatment from March 2003 to November 2017 were enrolled. Patients were followed up with periodic computed tomography (CT) scans to detect HCC recurrence. Patients who underwent treatment for HCC recurrence within 1 year after initiation of anti-HCV treatment were excluded. Laboratory data, including alanine aminotransferase (ALT) level, serum albumin level, and platelet count, were collected at baseline and timepoints after treatment initiation. Liver volume was evaluated at baseline and 24 and 48 weeks after treatment initiation using a CT volume analyzer. A linear mixed-effects model was applied to analyze the chronologic change in liver volume. The correlations between changes in ALT level, albumin level, and liver volume were also evaluated. RESULTS: Of 108 enrolled patients, 78 had cirrhosis. Serum albumin level continued to increase through 48 weeks after treatment initiation. A significant increase in liver volume was observed only in patients without cirrhosis (P = 0.005). There was a significant correlation between ALT level decrease and albumin level increase (P = 0.018). CONCLUSIONS: Improved liver albumin production with SVR was contributed by improved liver cell function rather than increased liver volume in patients with cirrhosis.
