ABSTRACT
Objective: To investigate the efficacy of chitinase-3-like protein 1 (CHI3L1) and Golgi protein 73 (GP73) in the diagnosis of cirrhosis and the dynamic changes of CHI3L1 and GP73 after HCV clearance in patients with chronic hepatitis C (CHC) treated with direct-acting antiviral drugs (DAAs). The comparison of continuous variables of normal distribution were statistically analyzed by ANOVA and t-test. The comparison of continuous variables of non-normal distribution were statistically analyzed by rank sum test. The categorical variables were statistically analyzed by Fisher's exact test and χ(2) test. Correlation analysis was performed using Spearman correlation analysis. Methods: Data of 105 patients with CHC diagnosed from January 2017 to December 2019 were collected. The receiver operating characteristic curve (ROC curve) was plotted to study the efficacy of serum CHI3L1 and GP73 for the diagnosis of cirrhosis. Friedman test was used to compare CHI3L1 and GP73 change characteristics. Results: The areas under the ROC curve for CHI3L1 and GP73 in the diagnosis of cirrhosis at baseline were 0.939 and 0.839, respectively. Serum levels of CHI3L1 and GP73 in the DAAs group decreased significantly at the end of treatment compared with baseline [123.79 (60.25, 178.80) ng/ml vs. 118.20 (47.68, 151.36) ng/ml, P = 0.001; 105.73 (85.05, 130.69) ng/ml vs. 95.52 (69.52, 118.97) ng/ml, P = 0.001]. Serum CHI3L1 and GP73 in the pegylated interferon combined with ribavirin (PR) group were significantly lower at the end of 24 weeks of treatment than the baseline [89.15 (39.15, 149.74) ng/ml vs. 69.98 (20.52, 71.96) ng/ml, P < 0.05; 85.07 (60.07, 121) ng/ml vs. 54.17 (29.17, 78.65) ng/ml, P < 0.05]. Conclusion: CHI3L1 and GP73 are sensitive serological markers that can be used to monitor the fibrosis prognosis in CHC patients during treatment and after obtaining a sustained virological response. Serum CHI3L1 and GP73 levels in the DAAs group decreased earlier than those in the PR group, and the serum CHI3L1 levels in the untreated group increased compared with the baseline at about two years of follow-up.

Objective: To observe the changes of serum uric acid levels and clinical characteristic in patients with chronic hepatitis C combined with hyperuricemia after direct antiviral agents (DAA) therapy. Methods: A prospective cohort study was used to investigate the risk of hyperuricemia in patients with chronic hepatitis C who received DAA treatment to obtain sustained virological response. The changes and factors influencing serum uric acid levels after 12 weeks of DAA treatment were observed. Comparisons between groups were performed using χ (2) test or Fisher's exact test, analysis of variance, Student's t test, or the non-parametric Mann-Whitney U test. Serum uric acid (SUA) changes, liver and kidney function indexes before and after treatment were compared by repeated measurement and paired t-test. Uric acid reduction was defined as a decrease in SUA from baseline at 12 weeks after treatment. Rates of change in eGFR, aspartate aminotransferase/platelet ratio, alanine aminotransferase and controlled attenuation parameter were defined from baseline (baseline to 12 weeks after treatment). Binary logistic regression analysis was used to compare the risk factors and factors influencing high and low uric acid level. Results: 161 cases with chronic hepatitis C who received DAA treatment were included, of which 19.3% patients were hyperuricemic. eGFR < 60 ml/(min·1.73 m(2)) and body mass index were independent risk factors for hyperuricemia in patients with chronic hepatitis C (eGFR: OR = 0.123, P = 0.002; body mass index: OR = 1.220, P = 0.002). SUA levels was changed significantly before treatment, at the end of treatment and at 12 weeks after treatment (327.96 vs. 320.76 vs. 314.92, F = 3.272, P = 0.042). At 12 weeks after treatment, SUA, liver stiffness, alanine aminotransferase and control attenuation parameters were all significantly lower than baseline (P < 0.05). The rate of increase in eGFR from baseline and the rate of decrease in controlled attenuation parameter during treatment were the factors influencing SUA reduction (eGFR: OR = 5124, P = 0.000; controlled attenuation index: OR = 0.010, P = 0.039). Conclusion: In chronic hepatitis C, reduced eGFR and body mass index are the risk factors for the development of hyperuricemia and a significant reduction in serum uric acid levels after DAA treatment can eradicate the virus.

Hepatitis C virus (HCV) RNA can be cleared from the blood circulation by direct antiviral treatment to achieve sustained virologic response (SVR). Studies have shown that SVR after direct antiviral therapy can reduce the incidence of hepatocellular carcinoma; however, monitoring for hepatocellular carcinoma is still needed. This review briefly summarizes and discusses the existing studies on the possible causes of hepatitis C secondary to HCC after antiviral therapy, which is mainly divided into epigenetic alterations and abnormal DNA methylation, HCV-related cirrhosis and abnormal DNA amplification, HBV reactivation, several aspects of occult HCV infection, and the effect of direct antiviral treatment on hepatocellular carcinoma recurrence. In few cases, direct antiviral treatment cannot completely prevent the occurrence and recurrence of hepatitis C-related hepatocellular carcinoma. Therefore, its mechanism needs to be studied and explored, and clinicians should also approach it with caution.

Objective: To evaluate the real-world efficacy and safety of sofosbuvir and velpatasvir (SOF/VEL) tablets in the treatment of Chinese patients with chronic HCV infection. Methods: An open-label, single-center, prospective clinical study was conducted in a county in northern China. A total of 299 cases were enrolled. Of these, 161 cases with chronic hepatitis C and 73 cases with compensated cirrhosis received SOF/VEL for 12 weeks. 65 cases with decompensated cirrhosis received SOF/VEL combined with ribavirin for 12 weeks (22 cases) or SOF/VEL for 24 weeks (43 cases). Virological indicators, liver and renal function indexes, and liver stiffness measurement were detected at baseline, the fourth week of treatment, the end of treatment, and the 12-weeks of follow-up. Adverse reactions and laboratory abnormalities were observed during the course of treatment . The primary endpoint was undetectable rate of HCV RNA (SVR12) at 12 weeks of follow-up with the use of modified intention-to-treat (mITT) approach. Measurement data between two groups were compared using t-test. One Way ANOVA was used for comparison between multiple groups. Enumeration data were analyzed by chi-square test or Fisher's exact test. Results: 291 cases had completed treatment. HCV RNA was undetectable after 12 weeks of follow-up, and the SVR12 rate was 97.3% (95% confidence interval: 95.4%-99.3%). Among them, 97.4% of genotype 1b, 96.4% of genotype 2a, and 100% of those with undetected genotype achieved SVR12. The SVR12 rates in patients with chronic hepatitis C, compensated and decompensated liver cirrhosis were 98.1%, 98.6% and 93.8%, respectively. An improvement in alanine aminotransferase, aspartate aminotransferase and other liver biochemical indicators accompanied with virological clearance and reduced liver stiffness measurement was observed in patients with compensated cirrhosis, with statistically significant difference. There was no significant abnormality in renal function before and after treatment. The most common adverse reactions were fatigue, headache, epigastric discomfort and mild diarrhea. The overall adverse reactions were mild. One patient died of decompensated liver cirrhosis combined with massive upper gastrointestinal bleeding, which was unrelated to antiviral treatment. Four patients discontinued treatment prematurely due to adverse events. Relapse was occurred in four cases, and drug-resistance related mutations were detected in three cases. Conclusion: Sofosbuvir and velpatasvir tablets in Chinese HCV-infected patients with different genotypes, different clinical stages or previously treated with pegylated interferon combined with ribavirin resulted in higher SVR12, indicating that the treatment safety profile is good.

Chronic hepatitis B virus (HBV) infection remains a global health burden. Timely and effective antiviral therapy is beneficial for patients with HBV infection. With existing antiviral drugs, including nucleos(t)ide analogs and interferon-alfa, patients can achieve viral suppression with improved prognosis. However, the rate of hepatitis B surface antigen loss is low. To achieve a functional cure and even complete cure in chronic hepatitis B patients, new antivirals need to be developed. In this review, we summarized the advantages and disadvantages of existing antiviral drugs and focused on new antivirals including direct-acting antiviral drugs and immunotherapeutic approaches.

Contexte et objectifs. Les hépatites virales chroniques constituent un problème de santé publique en Côte-d'Ivoire. Très peu de malades accèdent au traitement en raison des coûts élevés du bilan et du traitement. L'objectif de la présente étude était d'évaluer les coûts du bilan et du traitement des hépatites virales chroniques. Méthodes. Il s'agissait d'une étude observationnelle transversale analytique réalisée, du 1er mars 2019 au 31 juillet 2019, en consultation d'hépato-gastroentérologie du CHU de Yopougon. Les variables étudiées étaient les paramètres sociodémographiques et économiques. Résultats. Au total, 136 patients (hommes 53, 6 %, âge moyen de 42 ans ± 12,2) ont été inclus. Plus de la moitié des patients (63,3 %) avaient un revenu mensuel n'excédant pas 490.39 USD. Le coût du bilan initial était de 223.13 USD et de 351.14 USD respectivement, pour l'hépatite virale B et C. Le ténofovir et l'interféron pégylé étaient gratuits. Le traitement par sofosbuvir + velpastavir coûtait 593.37 USD. Le bilan de suivi annuel était estimé à 237.02 USD pour l'hépatite virale B, 225.58 USD pour l'hépatite virale C. Conclusion. Le bilan et le traitement des hépatites virales chroniques ont un coût prohibitif pour les patients malgré la couverture maladie universelle.
Context and objectives. Chronic viral hepatitis is a public health problem in Côte-d'Ivoire. A significant number of patients have little access to treatment due to the high costs of assessment and treatment. The objective of our study was to evaluate the costs of assessments and treatment of chronic viral hepatitis. Methods. This was an analytical cross-sectional observational study from March 1, 2019 to July 31, 2019 in the HepatoGastroenterology Consultation Service at the Yopougon University Hospital. The variables studied were socio-demographic and economic parameters. Results. 136 patients (men 53.6 %, average age 42 ± 12.2 years) were included. More than half of the patients (63.3 %) had a monthly income not exceeding 490.39 USD. The cost of the initial assessment was 223.13 USD and 351.14 USD for viral hepatitis B and C, respectively. Tenofovir and pegylated interferon were free of charge. Treatment with sofosbuvir + velpastavir cost 593.37 USD. The annual follow-up assessment was estimated at 237.02 USD for viral hepatitis B and 225.58 USD for viral hepatitis C. Conclusion. The assessment and treatment of chronic viral hepatitis have a cost that remains high for patients despite the universal health coverage.

Abstract This study aimed to evaluate the effectiveness and safety of direct-acting antivirals in a Unified Health System pharmacy of Londrina, Brazil. A descriptive observational study was performed from June 2017 to June 2018. Sociodemographic, clinical, and therapeutic variables of patients were collected from secondary data sources. Effectiveness was evaluated by sustained virologic response (SVR) and safety was evaluated by adverse events (AEs) and drug interactions (DIs). The mean population (N=30) was 56.6±11.3 years old and almost all patients had comorbidities (93.3%) and concomitant drugs (96.7%). Effectiveness evaluation was possible in 17 patients, and all of them (100.0%) achieved SVR. Eighteen patients (60.0%) reported 38 AEs, mostly mild, such as stomach symptoms and headache. No statistical relation was found between AE occurrence and treatment duration, Ribavirin use, number of comorbidities or number of concomitant drugs. A total of 48 DIs were reported, 18 being severe, and were managed by the pharmacist. The study indicates that the treatment was effective and safe.

Segundo o Ministério da Saúde, o número de casos notificados e confirmados de hepatite C no período entre 1999 e 2020 foi de 262.815 casos no Brasil. Em 2016, a OMS estabeleceu como objetivo global que as hepatites não fossem mais um problema de saúde pública em 2030. A partir de 2015, os agentes antivirais de ação direta (DAA) começaram a ser utilizados nessa terapêutica. O tratamento atual da hepatite C com os novos DAA revolucionou o cenário mundial com taxas de cura de até 98%. O objetivo desse artigo é apresentar e discutir o tratamento realizado com DAA em pacientes com hepatite C crônica em um centro de referência no Estado do Rio de Janeiro no período entre novembro de 2015 e julho de 2019. Trata-se de um estudo observacional, prospectivo e descritivo de pacientes com hepatite C crônica tratados com DAA no ambulatório de hepatologia de um hospital de referência. No presente estudo pode ser concluído que a maioria dos pacientes evoluiu para a cura após o tratamento. Foi possível concluir também que os esforços idealizados pela OMS para que o vírus da hepatite C seja erradicado estão ocorrendo de forma positiva e que com as novas DAAs é possível ter um número satisfatoriamente alto de RVS, evitando, assim, desfechos desfavoráveis, como por exemplo, o surgimento de carcinoma hepatocelular.
According to the Ministry of Health, the number of notified and confirmed cases of hepatitis C in the period between 1999 and 2020 was 262,815 cases in Brazil. In 2016, the WHO established as a global goal that hepatitis was no longer a public health problem in 2030. As of 2015, direct action antiviral agents (DAA) began to be used in this therapy. The current treatment of hepatitis C with the new DAA has revolutionized the world scenario with cure rates of up to 98%. The aim of this article is to present and discuss the treatment performed with DAA in patients with chronic hepatitis C in a reference center in the state of Rio de Janeiro between November 2015 and July 2019. This is an observational, prospective and descriptive study of patients with chronic hepatitis C treated with DAA in the hepatology clinic of a reference hospital. In the present study, it can be concluded that most patients evolved to cure after treatment. It was also possible to conclude that the efforts idealized by the WHO to eradicate the hepatitis C virus are occurring in a positive way and that with the new DAAs it is possible to have a satisfactorily high number of SVR, thus avoiding unfavorable outcomes, such as the appearance of hepatocellular carcinoma.

ABSTRACT According to the World Health Organization, 71 million people live with chronic hepatitis C. The treatment of this disease requires assistance from specialized physicians and a highly complex health care system. The prison population has been recognized as being at a high risk of acquiring confinement-related infections, including viral hepatitis. Hepatitis C virus (HCV) infection is a primary cause of death owing to liver disease among liberty-deprived individuals. Generally, prisons do not have adequate isolation wards for persons with communicable diseases, and overcrowding is a risk factor for this population. Besides prison overcrowding, violence, poor sanitary conditions, low socioeconomic status, social isolation, and emotional instability are factors that can lead detainees to adopt unhealthy habits that make them more susceptible to infections, including HCV, and complicate effective treatment. The Criminal Execution Law 7, 210 of July 11, 1984, in Article 14, grants preventive and curative medical, dental, and pharmacological healthcare to detainees. However, adequate hepatitis C treatment is rarely provided at prisons owing to social stigma and lack of knowledge on the severity of this condition or because most detainees are unaware of their condition. Given the multiple limitations imposed by the prison system model, implementing measures to treat diseases effectively is challenging. However, it is possible to eliminate hepatitis C in prisons in the long term through the coordinated action of public health institutions and the prison system.
RESUMO De acordo com a Organização Mundial da Saúde, 71 milhões de pessoas vivem com hepatite C crônica. O tratamento dessa doença requer assistência de médicos especializados e um sistema de saúde de alta complexidade. A população carcerária tem sido reconhecida como sendo de alto risco de adquirir infecções relacionadas às condições de confinamento, incluindo hepatites virais. O vírus da hepatite C (VHC) é uma causa primária de morte por doença hepática em pessoas privadas de liberdade. Geralmente, as prisões não possuem locais adequados para isolamento de pessoas com doenças transmissíveis e a superlotação é um fator de risco para essa população. Além da superlotação das prisões, violência, más condições sanitárias, baixo nível socioeconômico, isolamento social e instabilidade emocional são motivos adicionais que induzem os detidos a praticar hábitos não saudáveis, que os tornam mais suscetíveis a certas infecções (incluindo VHC) e complicam o tratamento específico. A Lei de Execução Penal n. 7.210, de 11 de julho de 1984, em seu artigo 14, garante assistência preventiva e curativa à saúde, incluindo assistência médica, farmacêutica e odontológica aos detidos. No entanto, o tratamento adequado da hepatite C é raramente fornecido nas prisões devido estigma social ou falta de conhecimento de sua condição ou porque a maioria dos detidos não tem conhecimento de sua condição. Devido a múltiplas limitações impostas pelo modelo prisional, a implementação de medidas para o tratamento eficaz de doenças é desafiadora. No entanto, é possível eliminar a hepatite C em um ambiente prisional de longa permanência através de ações coordenadas de instituições de saúde pública e o sistema prisional.

La infección por virus de la hepatitis C en pediatría se produce principalmente por transmisión vertical. La historia natural en niños consiste en alta tasa de eliminación espontánea, infección asintomática o cambios histológicos mínimos. Las complicaciones suelen observarse en la adolescencia o en la edad adulta. El tratamiento clásico con interferón pegilado y ribavirina presenta efectos adversos, es de duración prolongada y logra una respuesta virológica sostenida (RVS) en el 50 % de los pacientes con infección por genotipo 1. Los nuevos antivirales de acción directa se encuentran disponibles para su indicación a partir de los 12 años, con excelente tolerancia y alta tasa de RVS. Se sugiere conducta terapéutica expectante en pacientes asintomáticos hasta acceder a la medicación. Reportamos el caso de un adolescente con hepatitis C crónica sin cirrosis que recibió tratamiento durante 12 semanas con ledipasvir/sofosbuvir y se logró una RVS.
Hepatitis C virus infection in children occurs mainly through vertical transmission. The natural history at this age consists in a high rate of spontaneous clearance, asymptomatic infection, or minimal histological changes. Disease complications are commonly seen in adolescence or adulthood. The classic treatment with pegylated interferon and ribavirin presents adverse effects, prolonged duration and achieves sustained viral response (SVR) in 50 % of patients with genotype 1 infection (the most frequent). New direct-acting antiviral treatments have been available in recent years for their indication from 12 years of age with excellent tolerance and a high SVR rate. Expectant therapeutic behavior is suggested in asymptomatic patients until they can access to them. We report the case of an adolescent with chronic hepatitis C without cirrhosis who received 12 weeks treatment with ledipasvir/sofosbuvir, achieving SVR.

Abstract The clinical management of hepatitis C virus (HCV) infection presents several challenges today. WHO's goal is to eliminate it by 2030. It is an ambitious goal and difficult to meet given the barriers to care that arise. This is possible today thanks to the discovery of direct-acting antivirals (DAAs). This treatment achieves a high cure rate and is virtually free of adverse effects. To try to comply with this, in addition to the use of DAAs, it is necessary to reduce the rate of undiagnosed patients and facilitate the access of those diagnosed to care and treatment. For that, it is proposed to carry out a simplified treatment of HCV. This involves reducing controls during and after treatment. This simplification varies according to whether patients have cirrhosis or not. In this way, it seeks to increase significantly the number of patients treated and cured to reduce the burden on public health of this disease.
Resumen El manejo clínico de la infección por el virus la hepatitis C (HCV) presenta varios desafíos en la actualidad. El objetivo de la OMS es eliminarlo para el 2030. Es un objetivo ambicioso y muy difícil de cumplir dadas las barreras al cuidado que se presentan. Sin embargo, esto es posible hoy gracias al descubrimiento de los antivirales de acción directa (AAD). Este tratamiento logra una alta tasa de curación y prácticamente está libre de efectos adversos. Para tratar de cumplirlo, además del uso de los AAD, es nece sario reducir la tasa de pacientes no diagnosticados y facilitar el acceso de los diagnosticados al cuidado y el tratamiento. Para eso se propone llevar adelante el tratamiento simplificado del HCV. Esto implica reducir los controles durante y después del tratamiento. Esta simplificación varía según los pacientes tengan o no cirrosis. De esta manera se busca aumentar significativamente el número de pacientes tratados y curados para así poder reducir el impacto en la salud pública de esta enfermedad.

Abstract In addition to liver disease, the hepatitis C virus (HCV) has been associated with autoimmune phenomena, such as mixed cryoglobulin and glomerulonephritis (GN). Until recently, both chronic hepatitis and HCV extra-hepatic manifestations were treated with peg-interferon plus ribavirin, however these drugs presented low efficacy and induced severe side effects. Nowadays, the HCV chronic hepatitis has been treated with direct acting antivirals (DAA), but studies on the DAA therapy for HCV-associated glomerulonephritis are scarce. Here, we describe two cases of HCV-associated glomerulonephritis that were treated with DAAs. In these two cases, previously experienced to peg-interferon plus ribavirin, the sofosbuvir plus simeprevir therapy was effective, without significant side effects, and interrupted the evolution of at least 20 years of both hepatic and renal diseases. These cases join the seven previously described cases that were treated with this DAAs association.
Resumo Além da doença hepática, o vírus da hepatite C (HCV) tem sido associado a fenômenos autoimunes, como crioglobulinemia mista (CM) e glomerulonefrite (GN). Até recentemente, a hepatite crônica e as manifestações extra-hepáticas do HCV eram tratadas com peg-interferon com ribavirina; no entanto, essas drogas apresentavam baixa eficácia e induziam efeitos colaterais graves. Atualmente, a hepatite crônica por HCV tem sido tratada com antivirais de ação direta (AAD), mas estudos sobre a terapia com AAD para glomerulonefrite associada ao HCV são escassos. Aqui, descrevemos dois casos de glomerulonefrite associada ao HCV que foram tratados com AAD. Nestes dois casos, previamente tratados com peg-interferon e ribavirina, a terapia com sofosbuvir com simeprevir foi eficaz, sem efeitos colaterais significativos, e interrompeu a evolução de pelo menos 20 anos de doenças hepáticas e renais. Esses casos se juntam aos sete casos descritos anteriormente que foram tratados com essa associação de AAD.

Resumen La principal infección viral transmisible por sangre es actualmente la debida al virus de hepatitis C (VHC). Uno de los mayores obstáculos para el logro de su control en la Argentina se relaciona con las dificultades de acceso al diagnóstico y tratamiento oportuno de las personas infectadas. Este estudio se realizó con el objetivo de caracterizar a los pacientes infectados con VHC que iniciaron tratamiento con antivirales de acción directa (AAD) y describir la experiencia vinculada al tratamiento. Se seleccionaron las historias clínicas de 82 pacientes, 44 (53.7%) de sexo masculino, 37 (45.1%) de sexo femenino, y uno (1.2%) transgénero. La media de edad fue de 49 años. Se halló una frecuencia de cirrosis de 39%, 32 pacientes, coinfección con HIV en 48 (58.5%) y con VHB en 27 (32.9%). En 52 (63.4%) no se observó ningún factor de riesgo claramente asociado a infección. Todos completaron la terapia, de ellos 72 (87.8%) efectuaron el control para confirmar respuesta viral sostenida (RVS), que fue de 98.6%. Concluimos que el testeo universal debe implementarse por sobre el testeo con enfoque de riesgo, y que debe promoverse un criterio de atención simplificado y descentralizado, reservando la atención especializada para pacientes con cirrosis descompensada y cáncer de hígado.
Abstract Hepatitis C virus (HCV) infection is currently the main blood-borne viral infection. One of the main obstacles to achieving its control in Argentina is related to difficulties in accessing the diagnosis and timely treatment of infected people. We carried out this study with the aim of characterizing the HCV-infected patients who started treatment with direct-acting antivirals (DAAs) and to describe the experience related to treatment. The medical records of 82 patients, 44 (53.7%) male, 37 (45.1%) female, and one (1.2%) transgender, were selected. The mean age was 49 years. We report a frequency of cirrhosis, 39%, in 32 patients, coinfection with HIV in 48 (58.5%) and with HBV in 27 (32.9%). In 52 patients (63.4%), no risk factor clearly associated with infection was observed. All completed the therapy, of them 72 (87.8%) carried out the control to confirm sustained viral response (SVR), that attained 98.6%. We conclude that universal testing should be implemented over testing based on a risk approach, and that a simplified and decentralized care criterion should be promoted, reserving specialized care for patients with decompensated cirrhosis and liver cancer.

Hepatitis C virus (HCV) is one of the leading causes of chronic liver disease. HCV is not only related to hepatic malignancies but may also promote lymphoid neoplasms. Currently, research has confirmed HCV-related lymphoma, including marginal zone lymphoma (MZL), lymphoplasmacytic lymphoma (LPL), follicular lymphoma (FL), diffuse large B-cell lymphoma (DLBCL), and Burkitt lymphoma (BL). Many types of research have shown that antiviral therapy can improve or even remission several HCV-related lymphomas. The direct-acting antiviral agents (DAAs) (such as NS5A protease inhibitors, NS4/4A protease inhibitors and viral polymerase inhibitors) have shown clinical advantages of high efficacy and low side effects for both virus elimination and tumor regression in several HCV-related lymphomas, which may make the selected HCV-related lymphoma patients treated without chemotherapy. In this review the research progress and development direction of antiviral therapy in treating HCV-related lymphoma has summarized briefly.

Viral hepatitis C is one of the important causes of liver cirrhosis and hepatocellular carcinoma. There are approximately 10 million cases of chronic hepatitis C virus (HCV) infection in China. However, over 70% of HCV infections of China have not yet been detected. According to the goal of "eliminating viral hepatitis as a public health threat by 2030" of the World Health Organization Viral Hepatitis Strategy, and the fact that medical institutions remain the main places for detecting HCV infections or patients in China at present, we established the " In-hospital process for viral hepatitis C screening and management in China (Draft)", with intention to promote the multidisciplinary collaboration and cooperation among the departments of clinic, laboratory, infection control, management, and etc. in medical institutions, and strengthen consultation and referral of patients with detected HCV antibodies and advance the diagnosis and antiviral treatment of patients with chronic hepatitis C.

ABSTRACT A retrospective cohort of 11,308 chronic hepatitis C infected patients treated with regimens that included Sofosbuvir (SOF), Daclatasvir (DCV), Simeprevir (SMV), or an association of Ombitasvir, Veruprevir/Ritonavir and Dasabuvir (3D) with or without Ribavirin (RBV) were assessed for sustained virologic response (SVR) or viral cure after a 12-week treatment. Logistic regression analyses were used to identify factors independently associated with positive response to direct-acting antivirals (DAA)-based therapies.Overall 57.1% were male; 48.3% self-identified as white; 78.3% were over 50 years old; 44.1% were from the Southeast region; 47.7% had genotype 1b; and 84.5% were treated for 12 weeks. The SVR rates with DAAs ranged from 87% to 100%. Genotypes 1 and 4 had higher SVR rates (96.3-100%), and genotypes 2 and 3 had SVR of 90.6-92.2%, respectively. Treatment durations of 12 and 24 weeks were associated with an average SVR of 95.0% and 95.9%, respectively. Females were half as likely (OR 0.5; 95% CI 0.4−0.6) to have a negative response to therapy compared to males, and those with genotypes 2 and 3 were one and half fold more likely (OR 1.5-2.2; 95 CI% 0.7-2.9; 1.2-3.6 and OR 2.7-2.8; 95% CI 2.0-3.8, respectively) to not have SVR compared to genotype 1. Patients in the age-range of 50-69 years old were 1.2-fold (OR 1.2; 95% CI 0.7-1.9) more likely to not have SVR compared to other age groups, although not statistically significant.This study is the first of this magnitude to be held in a Latin-American country with high SVR results, supported by a free-of-charge universal and public health system. The high performance found in this study gives support to the Brazilian public health policy decision of adopting DAA-based therapies as a strategy to eliminate HCV by 2030.

OBJECTIVES: The aim was to prospectively assess the variation in liver stiffness (LS) and the associated factors for LS progression in a cohort of naïve, non-responder (NR), and sustained virological response (SVR) chronic hepatitis C (CHC) patients. METHODS: This was a longitudinal study on CHC patients prospectively followed with serial elastography (Fibroscan®). The LS progression rate was determined, and the associated factors for progression were assessed using multiple linear regression analysis. RESULTS: A total of 406 patients were followed up for 44 (35-53) months [naïve (29%), NR (24%), and SVR (47%)]. At the end of the follow-up period, the SVR group had a significant decrease in LS [11.8 (9.2) vs. 8.8 (8.4) kPa (p<0.001)], the NR group had a significant increase in LS [6.6 (5.2) vs. 7.1 (4.5) kPa (p=0.069)], and the naïve group had no change in LS [6.3 (3.0) vs. 6.0 (3.8) kPa (p=0.22)]. The related factors for LS progression were lack of SVR (p=0.002) and diabetes (p=0.05). In the non-diabetic SVR group, a negative rate of progression (-0.047 kPa/month) was observed, whereas in the diabetic SVR group, a positive rate of progression (+0.037 kPa/month) was observed. The highest rate of progression was observed in NR with diabetes at the rate of +0.044 kPa/month. CONCLUSION: LS in diabetes patients progresses despite SVR, suggesting the need for a close follow-up of this group post-treatment considering the risk of progression of liver disease even after SVR.

OBJECTIVES: Despite higher rates of sustained virologic response (SVR), important concerns remain when patients with decompensated cirrhosis due to hepatitis C virus (HCV) are treated with direct-acting antiviral agents (DAA). Questions include efficacy, safety, and the magnitude of liver function improvement. Here, we aimed to evaluate HCV treatment data in this specific population in Brazil. METHODS: We included 85 patients with decompensated cirrhosis submitted to HCV therapy with DAA followed at two academic tertiary centers in the southeastern region of Brazil. RESULTS: Seventy-nine patients (92.9%) were Child-Pugh (CP) score B, and six (7.1%) were CP score C. The mean MELD score was 12.86. The most common treatment was sofosbuvir plus daclatasvir±ribavirin for 24 weeks. The overall intention-to-treat (ITT) SVR rate was 87.4% (74/85) and modified-ITT 96.1% (74/77). ITT SVR was associated with lower baseline INR values (p=0.029). Adverse events (AE) occurred in 57.9% (44/76) of patients. Serious AE were reported in 12.8% (10/78), and were related to the presence of hepatic encephalopathy (p=0.027). SVR was associated with improvement in CP (p<0.0001) and MELD scores (p=0.021). Among baseline CP score B patients with SVR, 46% (29/63) regressed to CP score A. Ascites was independently associated with no improvement in liver function in patients who achieved SVR (p=0.001; OR:39.285; 95% CI:4.301-258.832). CONCLUSIONS: Patients with decompensated HCV cirrhosis showed a high SVR rate with interferon-free therapy. Early liver function improvement occurred after successful HCV eradication. However, long-term follow-up of these patients after SVR remains strongly advised.
