Retrospective Evaluation of Hepatitis C Awareness in Turkey Through Two Decades.

BACKGROUND/AIMS: Chronic hepatitis C (CHC) is the only viral infection that can be treated with oral antiviral agents. However, CHC awareness is a major barrier to the World Health Organization's target of eliminating hepatitis C virus (HCV) by 2030. Here, CHC awareness trends were analyzed in Hacettepe University Hospital, Turkey, between January 2000 and December 2017. MATERIALS AND METHODS: Central laboratory data were retrospectively analyzed for HCV test results (anti-HCV, HCV RNA, HCV genotype). After combining 548,141 anti-HCV test results, 395,103 cases were analyzed. The following two parameters were defined for CHC awareness: (1) the presence of HCV RNA results for anti-HCV positives and (2) the presence of a genotype result for HCV RNA positives. RESULTS: Anti-HCV positives were older than negatives (mean age-years ± SD, 59.4 ± 19.0 vs. 44.0 ± 18.9), and the positivity rate was higher in women than in men (1.4% vs. 1.0%). Anti-HCV positivity decreased from 3.1% to 0.6% from 2000 to 2015 and subsequently stabilized. The overall percentage of RNA testing among anti-HCV positives was 53.1% (range, 20%-70%), which stabilized at approximately 50% after 2010. The genotyping rate for RNA positives varied between 40% and 70%. The main genotype identified was genotype 1 (85.7%). CONCLUSION: In an ideal CHC awareness state, all anti-HCV positives should undergo RNA testing, and genotyping should be performed when RNA tests are positive. However, even in our referral center, the combined rate of RNA and genotype testing was only approximately 50% during the last 10 years.

MAFLD considerations as a part of the global hepatitis C elimination effort: an international perspective.

BACKGROUND: The World Health Organization (WHO) set a goal to eliminate hepatitis C (HCV) infection globally by 2030, with specific targets to reduce new viral hepatitis infections by 80% and reduce related deaths by 65%. However, an overlooked aspect that may hinder these efforts is the impact other liver diseases could have by continuing to drive liver disease progression and offset the beneficial impact of DAAs on end-stage liver disease and hepatocellular carcinoma (HCC). In particular, the decrease in HCV prevalence has been countered by a marked increase in the prevalence of metabolic-associated fatty liver disease (MAFLD). AIMS: To review the potential interaction of HCV and MAFLD. METHODS: We have reviewed the literature relating to an arrange of interaction of HCV, metabolic dysfunction and MAFLD. RESULTS: In this viewpoint, international experts suggest a holistic and multidisciplinary approach for the management of the growing number of treated HCV patients who achieved SVR, taking into consideration the overlooked impact of MAFLD for reducing morbidity and mortality in people who have had HCV. CONCLUSIONS: This will strengthen and improve the continuum of care cascade for patients with liver disease(s) and holds the potential to alleviate the cost burden of disease; and increase quality of life for patients following DAAs treatment.

Presentation and Outcomes of Hepatocellular Carcinoma in the Arabian Peninsula: A Review of a Single Institution Experience in the Sorafenib Era.

PURPOSE: There is a growing evidence showing that there are geographic differences in hepatocellular carcinoma (HCC). Little is known about the characteristics of hepatocellular carcinoma in the Arabian Peninsula. The present study examines the presentation and outcomes of HCC in a single institution. METHODS: A retrospective chart review of patients presented with advanced-stage HCC to Kuwait Cancer Control Center (KCCC) between 2008 and 2018 was conducted. Data collected included patients demographics, HCC risk factors, performance status, Child-Pugh score, pick up of sorafenib, and survival. RESULTS: About 111 cases were analyzed. The mean age of the cohort was 61.8 ± 11.4 years and 94 patients (84.7%) were males. HCV and diabetes were the most common risk factors for HCC and presented in 60 patients (54.1%) and 45 patients (40.5%), respectively. About 78 (70.3%) patients had an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1 at presentation. Only 29 (26.1%) patients presented with Child-Pugh class A, while 42 (40.4%) patients received sorafenib. The median overall survival was only 3 months. CONCLUSIONS: In our cohort, HCV and diabetes were the main risk factors for HCC. The majority of patients was not amenable to sorafenib treatment and carries a very poor prognosis.

Prevalence and Characteristics of Chronic Hepatitis C Among Asian Americans Are Distinct From Other Ethnic Groups.

GOAL: The goal of this study was to determine the prevalence and characteristics of chronic hepatitis C (CHC) among Asian Americans compared with other ethnicities. BACKGROUND: Chronic hepatitis C virus (HCV) affects an estimated 2.7 million in the United States, but there are limited data on HCV among Asian Americans. STUDY: A total of 3,369,881 adults over the age of 18 who were patients of the integrated health care system in Southern California and 4903 Asian participants at community hepatitis screenings were included in a cross-sectional study. Variables included HCV serology, HCV genotype, comorbidities, and coinfections. RESULTS: The prevalence of CHC was 1.3% in the general population (8271 adults) and 0.6% among Asians. The prevalence of CHC was significantly higher in the 1945-1965 birth cohort with 2.7% (5876) in the general population and 1.0% (313) among Asians (P<0.001). Asians had the highest rates of hepatitis B coinfection (2.9% vs. 0.2%, P<0.001). The distribution of genotypes among Asians differed from the general population with the most common genotype being 1b (27.5%) and a higher presence of genotype 6 (9.5%) (P<0.001). The presence of cirrhosis was 17.6% in Asians. Disaggregated Asian data showed that CHC was highest among Vietnamese and Cambodian and that genotype 6 was predominant among these 2 subgroups. CONCLUSIONS: The prevalence of chronic HCV was significantly lower in Asians compared with other ethnicities. However, disaggregated data among Asians showed the highest prevalence rates among adults from Vietnam and Cambodia.

Monitoring hepatitis C virus treatment rates in an Opioid Treatment Program: A longitudinal study.

BACKGROUND: Direct-acting antivirals (DAAs) are recommended for the treatment of hepatitis C virus (HCV) infection in patients treated with methadone or buprenorphine. AIM: To assess HCV treatment rates in an Opioid Treatment Program (OTP). METHODS: This longitudinal study included 501 patients (81.4% men, median age: 45 years; interquartile range: 39-50 years) enrolled in an OTP between October 2015 and September 2017. Patients were followed until September 2019. Data on socio-demographics, substance use, HCV infection, human immunodeficiency virus (HIV) infection and laboratory parameters were collected at entry. We analyzed medical records to evaluate HCV treatment. Kaplan-Meier methods and Cox regression models were used to analyze the DAA treatment uptake and to identify treatment predictors. RESULTS: Prevalence of HCV and HIV infection was 70% and 34%, respectively. Among anti-HCV-positive (n = 336) patients, 47.2%, 41.3%, and 31.9% used alcohol, cannabis, and cocaine, respectively. HCV-RNA tests were positive in 233 (69.3%) patients. Twentyeight patients (8.3%) cleared the infection, and 59/308 (19.1%) had received interferon-based treatment regimens before 2015. Among 249 patients eligible, 111 (44.6%) received DAAs. Treatment rates significantly increased over time from 7.8/100 person-years (p-y) (95%CI: 5.0-12.3) in 2015 to 18.9/100 p-y (95%CI: 11.7-30.3) in 2019. In a multivariate analysis, patients with HIV co-infection were twice as likely to receive DAAs (HR = 1.94, 95%CI: 1.21-3.12) than patients with HCV mono-infection. Current drug use was an independent risk factor for not receiving treatment against infection (HR = 0.48, 95%CI: 0.29-0.80). CONCLUSION: HCV treatment is evolving in patients with HCV-HIV co-infection. Ongoing drug use while in an OTP might negatively impact the readiness to treat infection.

Care quality and outcomes among US veterans with chronic hepatitis B in the hepatitis C direct-acting antiviral era.

Adherence to guideline-recommended hepatitis B virus (HBV) care is suboptimal. We hypothesized that national hepatitis C eradication efforts during the era from 2015 to 2017 would improve the quality of care for cHBV given increased recognition and specialty referrals for liver disease. The study described herein is a retrospective cohort study of veterans with at least one positive HBsAg (HBsAg+) result from 1 January 2003 to 31 December 2017 using the VA Corporate Data Warehouse (CDW) analysed by era (2003-2004, 2005-2009, 2010-2014, 2015-2017). Relevant covariates such as HCV co-infection, demographics, cirrhosis and baseline laboratory testing were obtained through previously validated approaches. We evaluated completion of process measures within 2 years of the index HBsAg + result: specialty care referral; testing of ALT, HBV-DNA, HBeAg and anti-HBe; testing for co-infection and/or vaccination for HAV, HCV, HDV and HIV; and hepatocellular carcinoma (HCC) surveillance among those meeting criteria. We also measured use of antiviral therapy in appropriate candidates (ALT ≥ 2 × ULN, HBV-DNA ≥ 2000 IU/mL). Of the 16 673 individuals with HBsAg + test results, 9,521 were confirmed as chronic HBV. Era-related (Era 3:2010-2014 vs Era 4:2015-2017) increases in guideline-recommended process measures included the following: outpatient visits with GI/ID specialists (78%-89%), HBV-DNA testing (73%-79%), HDV testing (27%-35%), appropriate HBV antiviral utilization (55%-70%) and HCC surveillance (40%-43%); all P < .0001. In the subset of HBV/HCV-co-infected patients, HCV DAA therapy was associated with a trend towards improved overall survival. In conclusion, the overall quality of care for HBV has significantly improved in the era of widespread HCV DAA therapy in an integrated health system possibly due to increased recognition and referral for liver disease.

Geographically Focused Collocated Hepatitis C Screening and Treatment in Los Angeles's Skid Row.

BACKGROUND: The inequitable prevalence of hepatitis C (HCV) in the homeless is a clinical and public health concern. Prior research estimates, at least one-quarter of homeless persons have been infected with HCV, yet linkage to care and treatment uptake remains marginal. AIM: To evaluate the feasibility of treating HCV in a homeless population. METHODS: Retrospective study of homeless individuals treated for HCV. Demographic information including risk factors was collected. Univariate analyses were performed. The proportion of patients linked to care and sustained viral response at 12 weeks post-treatment (SVR12) was measured. RESULTS: During the study period, 6767 individuals were screened for HCV. A total of 769 (11.4%) were found to have detectable HCV antibodies. Of the individuals with detectable HCV antibodies, 443 (57.6%) were viremic. Of the 443 viremic patients, 375 (84.7%) were linked to care. Among them, 59 patients began antiviral treatment and 95% (56/59) completed the course of therapy. The ITT was 83.1% (49/59), and the per-protocol virologic cure rate was 100% (49/49). CONCLUSION: The favorable linkage to care and cure outcomes in our study suggests that homeless persons may be more likely to engage in HCV screening and treatment when these services are located in the community for their use. Our study further lends support to the efficacy of care coordination programs to encourage movement through the HCV care continuum in vulnerable populations.

A Colocalized Hepatitis C Virus Clinic in a Primary Care Practice Improves Linkage to Care in a High Prevalence Population.

BACKGROUND: There is an urgent need to increase patient access to treatment of chronic hepatitis C virus (HCV) infection. We developed a colocalized HCV clinic integrated within a primary care practice. We report the prevalence of HCV and evaluate the impact of the integrated clinic on the HCV cascade of care. METHODS: We performed a retrospective study of patients with chronic HCV infection from 2 clinic practices, an integrated clinic practice and a similar nonintegrated clinic practice, between July 2015 and July 2016. Demographic, clinical, and HCV testing data were reviewed to estimate the prevalence of chronic HCV and to construct a cascade of care. RESULTS: A total of 8405 primary care patients were included; 4796 (57.1%) received an HCV antibody test and 390 (8.1%) were positive. A total of 310 patients with chronic HCV were included in the analysis. There were 119 patients eligible for linkage to care in the nonintegrated clinic, of which 80 (67.2%) were referred, 38 (31.9%) were linked, and 18 (15.1%) initiated treatment during the study period. Among the 70 patients eligible for linkage to care in the integrated clinic practice, 51 (72.9%) were referred, 38 (54.3%) were linked, and 16 (22.9%) initiated treatment. In a multivariable analysis, patients in the integrated clinic practice had significantly higher odds of being linked to care than patients in the nonintegrated clinic practice (adjusted odds ratio [OR] 2.5, 95% confidence interval [CI] = 1.3-4.8). CONCLUSIONS: We found a high seroprevalence of chronic HCV within our clinic population and demonstrate that a HCV clinic integrated into a primary care center increases linkage to care for patients with chronic HCV.

Cost effectiveness of treatment models of care for hepatitis C: the South Australian state-wide experience.

AIM: The objective was to study the long-term (lifetime) cost effectiveness of four different hepatitis C virus (HCV) treatment models of care (MOC) with directly acting antiviral drugs. METHODS: A cohort Markov model-based probabilistic cost-effectiveness analysis (CEA) was undertaken extrapolating to up to 30 years from cost and outcome data collected from a primary study involving a real-life Australian cohort. In this study, noncirrhotic patients treated for HCV from 1 March 2016 to 28 February 2017 at four major public hospitals and liaising sites in South Australia were studied retrospectively. The MOC were classified depending on the person providing patient workup, treatment and monitoring into MOC1 (specialist), MOC2 (mixed specialist and hepatitis nurse), MOC3 (hepatitis nurse) and MOC4 (general practitioner, GP). Incremental costs were estimated from the Medicare perspective. Incremental outcomes were estimated based on the quality-adjusted life years (QALY) gained by achieving a sustained virological response. A cost-effectiveness threshold of Australian dollar 50 000 per QALY gained, the implicit criterion used for assessing the cost-effectiveness of new pharmaceuticals and medical services in Australia was assumed. Net monetary benefit (NMB) estimates based on this threshold were calculated. RESULTS: A total of 1373 patients, 64% males, mean age 50 (SD ±11) years, were studied. In the CEA, MOC4 and MOC2 clearly dominated MOC1 over 30 years with lower costs and higher QALYs. Similarly, NMB was the highest in MOC4, followed by MOC2. CONCLUSION: Decentralized care using GP and mixed consultant nurse models were cost-effective ways of promoting HCV treatment uptake in the setting of unrestricted access to new antivirals.

Zinc deficiency and advanced liver fibrosis among HIV and hepatitis C co-infected anti-retroviral naïve persons with alcohol use in Russia.

BACKGROUND AND AIMS: Liver disease in people living with HIV co-infected with hepatitis C virus is a source of morbidity and mortality in Russia. HIV accelerates liver fibrosis in the setting of HCV co-infection and alcohol use. Zinc deficiency is common among people living with HIV and may be a factor that facilitates the underlying mechanisms of liver fibrosis. We investigated the association between zinc deficiency and advanced liver fibrosis in a cohort of HIV/HCV co-infected persons reporting heavy drinking in Russia. METHODS: This is a secondary data analysis of baseline data from 204 anti-retroviral treatment naïve HIV/HCV co-infected Russians with heavy drinking that were recruited into a clinical trial of zinc supplementation. The primary outcome of interest in this cross-sectional study was advanced liver fibrosis. Zinc deficiency, the main independent variable, was defined as plasma zinc <0.75 mg/L. Exploratory analyses were performed examining continuous zinc levels and fibrosis scores. Analyses were conducted using multivariable regression models adjusted for potential confounders. RESULTS: The prevalence of advanced liver fibrosis was similar for those with zinc deficiency compared to those with normal zinc levels, (27.7% vs. 23.0%, respectively). We did not detect an association between zinc deficiency and advanced liver fibrosis in the adjusted regression model (aOR: 1.28, 95% CI: 0.62-2.61, p = 0.51) nor in exploratory analyses. CONCLUSIONS: In this cohort of Russians with HIV/HCV co-infection, who are anti-retroviral treatment naïve and have heavy alcohol use, we did not detect an association between zinc deficiency or zinc levels and advanced liver fibrosis.

Integrated models of care for people who inject drugs and live with hepatitis C virus: A systematic review.

BACKGROUND: Despite the key role that people who inject drugs (PWID) play in the hepatitis C virus (HCV) epidemic, HCV treatment rates among this population have been historically low. Integrated models of HCV and substance use care have the potential to overcome some barriers to access; however, the evidence base is uncertain. This systematic review assesses the impacts of integrated HCV and substance use services on engagement in HCV care among PWID. METHODS: We searched five databases up to December 2018 to identify original quantitative studies evaluating the impacts of co-location of HCV and substance use services on engagement in the HCV cascade of care among adult PWID. We conducted a narrative synthesis, categorizing models based on patient entry point (a: HCV facility, b: substance use disorder (SUD) facility, and c: other facilities), and levels of integrated services offered (a: HCV/substance use testing only, b: HCV/substance use treatment, and c: testing/treatment + other services). RESULTS: A total of 46 articles corresponding to 44 original studies were included. Almost all studies (n = 42) were conducted in high-income countries and only six studies in the Direct-Acting Antiviral (DAA) era. Twenty-six studies discussed the integration of services at SUD facilities, one at HCV facilities, and seventeen at other facilities. Analysis of included studies indicated that overall integrated care resulted in improved engagement in HCV care (e.g., testing, treatment uptake and cure). However, the quality of evidence was predominantly low to moderate. CONCLUSIONS: Available evidence suggests that integration of HCV and substance use services may improve engagement along the continuum of HCV care among PWID. Given limitations in data quality, and very few studies conducted in the DAA era and in low- and middle-income settings, further research is urgently needed to inform strategies to optimize HCV care access and outcomes among PWID globally.

Hepatite C no sistema público de saúde brasileiro: impacto da doença / Hepatitis c in the brazilian public health care system: burden of disease

ABSTRACT BACKGROUND: Infection by hepatitis C virus is one of the leading causes of chronic hepatitis C and cause severe burden for patients, families and the health care system. OBJECTIVE: The aims of this research were to assess the severity of liver fibrosis, comorbidities and complications of hepatitis C virus; to examine health-related quality of life (HRQoL), productivity loss and resource use and costs in a sample of Brazilian chronic hepatitis C, genotype 1, patients. METHODS: This was a cross-sectional multicenter study performed in genotype-1 chronic hepatitis C patients to assess disease burden in the Brazilian public health care system between November 2014 and March 2015. Patients were submitted to a liver transient elastography (FibroScan) to assess liver fibrosis and answered an interview composed by a questionnaire specifically developed for the study and three standardized questionnaires: EQ-5D-3L, HCV-PRO and WPAI:HepC. RESULTS: There were 313 subjects enrolled, with predominance of women (50.8%), caucasian/white (55.9%) and employed individuals (39.9%). Mean age was 56 (SD=10.4) years old. Moreover, 42.8% of patients who underwent FibroScan were cirrhotic; the most frequent comorbidity was cardiovascular disease (62.6%) and the most frequent complication was esophageal varices (54.5%). The results also showed that "pain and discomfort" was the most affected HRQoL dimension (55.0% of patients reported some problems) and that the mean HCV-PRO overall score was 69.1 (SD=24.2). Regarding productivity loss, the most affected WPAI:HepC component was daily activity (23.5%) and among employed patients, presenteeism was more frequent than absenteeism (18.5% vs 6.5%). The direct medical costs in this chronic hepatitis C sample was 12,305.72USD per patient in the 2 years study period; drug treatment costs represented 95.9% of this total. CONCLUSION: This study showed that most patients are cirrhotic, present high prevalence of cardiometabolic diseases and esophageal varices, reduced HRQoL mainly in terms of pain/discomfort, and work productivity impairment, especially presenteeism. Additionally, we demonstrated that hepatitis C virus imposes an economic burden on Brazilian Health Care System and that most of this cost is due to drug treatment.

RESUMO CONTEXTO: A infecção pelo vírus da hepatite C (HCV) é uma das principais causas de hepatite C crônica e provoca implicações graves para pacientes, familiares e sistema de saúde. OBJETIVO: Os objetivos deste estudo foram: analisar a gravidade da fibrose hepática, comorbidades e complicações da hepatite C; examinar a qualidade de vida relacionada à saúde (QVRS), a perda de produtividade e o uso de recursos e custos no sistema público por pacientes brasileiros com hepatite C crônica, genótipo tipo 1. MÉTODOS: Foi realizado um estudo transversal, multicêntrico em pacientes com hepatite C crônica genótipo-1 para avaliar a carga da doença no sistema público de saúde brasileiro entre novembro de 2014 e março de 2015. Os pacientes foram submetidos a uma elastografia hepática transitória (FibroScan) para avaliar a fibrose e a uma entrevista composta por um questionário desenvolvido para o estudo e cinco questionários padronizados: EQ-5D-3L, HCV-PRO, e WPAI:HepC. RESULTADOS: Foram recrutados 313 pacientes. A amostra foi composta predominantemente por mulheres (50,8%), caucasianos/brancos (55,9%) e indivíduos empregados (39,9%). A média de idade foi 56 (DP=10,4) anos. Em média, os pacientes com HCV esperaram 40,6 (DP=49,6) meses entre o diagnóstico e o primeiro tratamento. Ademais, 42,8% dos pacientes que realizaram o FibroScan tinham cirrose; a comorbidade mais frequente foi doença cardiovascular (62,6%) e a complicação mais comum as varizes esofágicas (54,5%). Os resultados também mostraram que "dor e desconforto" foi a dimensão de QVRS mais afetada (55,0% dos pacientes relataram alguns problemas) e que a média do escore do HCV-PRO foi 69,1 (DP=24,2). Em relação à perda de produtividade, o componente do WPAI:HepC mais afetado foi atividade diária (23,5%) e entre os pacientes empregados, presenteísmo foi mais frequente do que absenteísmo (18,5% vs 6,5%). Os custos diretos médicos totais com essa amostra foi de 12.305,72USD por paciente em um período de dois anos; o tratamento medicamentoso representou 95% desse total. CONCLUSÃO Esse estudo mostrou a maioria dos pacientes possui cirrose, apresenta alta prevalência de doenças cardiometabolicas e varizes esofágicas, QVRS reduzida principalmente em termos de dor/desconforto e dano na produtividade, especialmente presenteísmo. Adicionalmente, nós demonstramos que o HCV impõe uma carga econômica no sistema de saúde brasileiro e que os medicamentos correspondem à maioria dos custos.

Tratamento cirúrgico de lesões císticas do pâncreas: uma experiência unicêntrica / Surgical management of cystic lesions of the pancreas: a single-centre experience

ABSTRACT BACKGROUND: Cystic lesions of the pancreas represent a group of pancreatic diseases with great histological heterogeneity, varying from benign lesions, some of them with malignant potential, to overt malignant lesions. OBJECTIVE: To describe the cases of cystic lesions of the pancreas which underwent surgical intervention at a tertiary university hospital. METHODS: This is a retrospective population-based study (historical cohort) which was carried out enrolling individuals attended at the Outpatient service of Pancreas Surgery of the Hospital de Clínicas of Unicamp. The individuals underwent surgical procedures performed from January 2012 through December 2016. RESULTS: In the period evaluated, 39 cases of cystic lesions of the pancreas which underwent surgery were identified, 26 (66.6%) of which were female. The average age at diagnosis was 47.4±16.4 years (range, 18-73). In regards to symptoms, 35 (89.7%) were symptomatic. The average length of hospital stay was 10 days (range 4-76). Surgeries performed to treat the lesions depended on the localization and type of the lesions: cystojejunostomy (41%), distal pancreatectomy (36%), pancreaticoduodenectomy (15.4%), drainage of ruptured and/or infected pseudocyst (5.2%) and central pancreatectomy (2.6%). CONCLUSION: Cystic lesions of the pancreas are a group of lesions with a highly varying presentation and diagnostic approach and may require an also highly variable surgical treatment. An appropriate preoperative imaging diagnosis is essential for their management.

RESUMO CONTEXTO: As lesões císticas do pâncreas representam um grupo de doenças pancreáticas com grande heterogeneidade histológica, variando desde lesões benignas, algumas com potencial pré-maligno, até outras degeneradas para formas malignas. OBJETIVO: Descrever os casos de LCPs submetidos à intervenção cirúrgica em um hospital universitário terciário. MÉTODOS: Trata-se de um estudo retrospectivo populacional (coorte histórica) realizado com a participação de indivíduos atendidos no Ambulatório de Cirurgia do Pâncreas do Hospital de Clínicas da Unicamp. Os indivíduos foram submetidos a procedimentos cirúrgicos realizados no período de janeiro de 2012 a dezembro de 2016. RESULTADOS: No período avaliado, foram identificados 39 casos de lesões císticas do pâncreas operados, sendo 26 (66,6%) do sexo feminino. A idade média no diagnóstico foi de 47,4±16,4 anos. Em relação aos sintomas, 35 (89,7%) eram sintomáticos. O tempo médio de internação foi de 10 dias (variação de 4-76). As cirurgias realizadas para o tratamento das lesões dependeram da localização e do tipo das lesões: derivação pseudocisto-jejunal (41%), pancreatectomia distal (36%), pancreaticoduodenectomia (15,4%), drenagem de pseudocistos rotos e/ou infectados (5,2%) e pancreatectomia central (2,6%). CONCLUSÃO: As lesões císticas do pâncreas são um grupo de lesões cuja apresentação e abordagem diagnóstica são altamente heterogêneas e que podem requerer um tratamento cirúrgico altamente complexo e variável. Um diagnóstico pré-operatório adequado é essencial para definir o seu tratamento.

Vitamin D deficiency in hepatitis C virus infection: what is old? what is new?

In the past few years, a growing body of clinical evidence has highlighted the risk of vitamin D deficiency in patients with chronic hepatitis C and that vitamin D levels are associated with the course of hepatitis C virus (HCV) infection, adverse effects, and treatment response to peginterferon/ribavirin. Recently, studies have found that vitamin D status is related to drug resistance and increased risk of infection in patients with liver cirrhosis. Vitamin D-related gene polymorphisms have been found to explain the interactions between vitamin D deficiency and HCV infection, offering a new perspective toward understanding the current problems such as the development of insulin resistance and racial differences in sustained virological response. Studies have been conducted to determine whether vitamin D supplementation as an adjuvant yields a better result compared with traditional HCV treatment. Here, we provide a brief review of the past and present knowledge of vitamin D in HCV infection.

Determinants of survival following hepatocellular carcinoma in Egyptian patients with untreated chronic HCV infection in the pre-DAA era.

BACKGROUND AND STUDY AIMS: In this study we assessed rates and determinants of survival in people with untreated chronic HCV infection and hepatocellular carcinoma (HCC) in an Egyptian liver clinic setting. PATIENTS AND METHODS: This is a prospective cohort study of patients diagnosed with HCV-related HCC and undergoing HCC management at a national liver centre in Egypt in 2013-2014 and with a follow-up through 2016. RESULTS: A total of 345 patients diagnosed with HCV-related liver cirrhosis complicated by HCC were included. Median age at diagnosis was 57 years (IQR = 52, 62), the majority were male (78%) and Child-Turcotte-Pugh (CTP) class A (64%). At diagnosis Barcelona Clinic Liver Cancer staging (BCLC) was 0 (8%), A (48%), B (20%), C (17%), and D (7%). Most common HCC management modalities were transarterial chemoembolization (TACE) (42%), and radiofrequency ablation (RFA) (21%). Median survival following HCC was 22.8 months. Factors associated with poorer survival in adjusted analyses were INR (HR = 1.81, p = 0.01), alpha-foeto protein (AFP) ≥200 (HR = 1.41, p = 0.02), higher CTP score (HR = 2.48, p < 0.01), and advanced BCLC stage (HR = 1.85, p < 0.01). One year survival in patients with CTP A, B, and C was 85%, 71% and 32%, respectively. One year survival following RFA, TACE, combination RFA/TACE, and sorafenib was 93%, 79%, 80% and 60%, respectively. CONCLUSION: Survival following HCV-HCC in Egyptian patients undergoing HCC management in a specialised clinic setting is poor, although similar to high income country settings. CTP score is a key determinant of survival, even following adjustment for BCLC stage and HCC management.

Cost-effectiveness of hepatitis C screening and treatment linkage intervention in US methadone maintenance treatment programs.

BACKGROUND: We evaluated the cost-effectiveness of a hepatitis C (HCV) screening and active linkage to care intervention in US methadone maintenance treatment (MMT) patients using data from a randomized trial conducted in New York City and San Francisco. METHODS: We used a decision analytic model to compare 1) no intervention; 2) HCV screening and education (control); and 3) HCV screening, education, and care coordination (active linkage intervention). We also explored an alternative strategy wherein HCV/HIV co-infected participants linked elsewhere. Trial data include population characteristics (67% male, mean age 48, 58% HCV infected) and linkage rates. Data from published sources include treatment efficacy and HCV re-infection risk. We projected quality-adjusted life years (QALYs) and lifetime medical costs using an established model of HCV (HEP-CE). Incremental cost-effectiveness ratios (ICERs) are in 2015 US$/QALY discounted 3% annually. RESULTS: The control strategy resulted in a projected 35% linking to care within 6 months and 31% achieving sustained virologic response (SVR). The intervention resulted in 60% linking and 54% achieving SVR with an ICER of $24,600/QALY compared to no intervention from the healthcare sector perspective and was a more efficient use of resources than the control strategy. The intervention had an ICER of $76,500/QALY compared to the alternative strategy. From a societal perspective, the intervention had a net monetary benefit of $511,000-$975,600. CONCLUSIONS: HCV care coordination interventions that include screening, education and active linkage to care in MMT settings are likely cost-effective at a conventional $100,000/QALY threshold for both HCV mono-infected and HIV co-infected patients.

Recreational Drug and Psychosocial Profile in Chronic Hepatitis C Patients Seeking Antiviral Therapy.

BACKGROUND AND AIMS: Practitioners treating hepatitis C (HCV) provide healthcare to a special population with high rates of substance abuse and psychiatric disorders. We investigated the psychosocial profile in HCV patients and tested what variables affect commencement of antiviral therapy. MATERIAL AND METHODS: Recreational drug use (RDU), marijuana (THC), alcohol use, and psychiatric history were initially investigated with a questionnaire prior to history and physical. Following an educational intervention, we reinterrogated patients for RDU and THC use, and revision of initial statement was documented. Variables affecting commencement of antiviral therapy were analysed with logistic regression. RESULTS: Out of 153 patients, 140 (92%) answered the questionnaire. Intervention increased total yield by 6%, however, 39% (11/28) of those initially denying use revised their statement. Drug screening identified 9 more patients with RDU/THC use. Half of patients consuming alcohol were heavy drinkers, and psychiatric disease was identified in 54%. Only 73 (48%) of 139 patients eligible for antivirals received treatment. Multivariable analysis revealed that younger patients (OR = 1.04, 95% CI 1.01-1.08), and those testing positive on drug screen (OR = 0.41, 95% CI 0.19-0.92) were less likely to be treated. Denial by insurance and loss to follow-up were the most common reasons for not starting antiviral treatment. CONCLUSION: Substance abuse is highly prevalent among HCV patients, and it is difficult to tell prior from current users. Integral care of HCV patients should include a diligent screen for substance abuse and rehabilitation referral, aiming to increase the pool of patients eligible for antiviral therapy. This can only be achieved through a multidisciplinary approach.

Early Successes in an Open Access, Provincially Funded Hepatitis C Treatment Program in Prince Edward Island.

INTRODUCTION: The availability of curative hepatitis C therapies has created an opportunity to improve treatment delivery and access. Local providers, government, industry, and community groups in Prince Edward Island developed an innovative province-wide care model. Our goal was to describe the first year of program implementation. MATERIAL AND METHODS: Using a communitybased prospective observational study design, all chronic hepatitis C referrals received from April 2015 to April 2016 were recorded in a database. Primary analysis assessed the time from referral to assessment/treatment, as well as the number of referrals, assessments, and treatment initiations. Secondary objectives included: (1) treatment effectiveness using intention-to-treat analysis; and (2) patient treatment experience assessed using demographics, adverse events, and medication adherence. RESULTS: During the study period 242 referrals were received, 123 patients were seen for intake assessments, and 93 initiated direct-acting antiviral therapy based on medical need. This is compared to 4 treatment initiations in the previous 2 years. The median time from assessment to treatment initiation was 3 weeks. Eighty-two of 84 (97.6%, 95% CI 91.7 - 99.7%) patients for whom outcome data were available achieved sustained virologic response at 12 weeks post-treatment; 1 was lost to follow-up and 1 died from an unrelated event. In the voluntary registry, 39.7% of patients reported missed treatment doses. CONCLUSION: In conclusion, results from the first 12 months of this multi-phase hepatitis C elimination strategy demonstrate improved access to treatment, and high rates of safe engagement and cure for patients living with chronic hepatitis C genotype 1 infections.

HEPATITIS C IN THE BRAZILIAN PUBLIC HEALTH CARE SYSTEM: BURDEN OF DISEASE.

BACKGROUND: Infection by hepatitis C virus is one of the leading causes of chronic hepatitis C and cause severe burden for patients, families and the health care system. OBJECTIVE: The aims of this research were to assess the severity of liver fibrosis, comorbidities and complications of hepatitis C virus; to examine health-related quality of life (HRQoL), productivity loss and resource use and costs in a sample of Brazilian chronic hepatitis C, genotype 1, patients. METHODS: This was a cross-sectional multicenter study performed in genotype-1 chronic hepatitis C patients to assess disease burden in the Brazilian public health care system between November 2014 and March 2015. Patients were submitted to a liver transient elastography (FibroScan) to assess liver fibrosis and answered an interview composed by a questionnaire specifically developed for the study and three standardized questionnaires: EQ-5D-3L, HCV-PRO and WPAI:HepC. RESULTS: There were 313 subjects enrolled, with predominance of women (50.8%), caucasian/white (55.9%) and employed individuals (39.9%). Mean age was 56 (SD=10.4) years old. Moreover, 42.8% of patients who underwent FibroScan were cirrhotic; the most frequent comorbidity was cardiovascular disease (62.6%) and the most frequent complication was esophageal varices (54.5%). The results also showed that "pain and discomfort" was the most affected HRQoL dimension (55.0% of patients reported some problems) and that the mean HCV-PRO overall score was 69.1 (SD=24.2). Regarding productivity loss, the most affected WPAI:HepC component was daily activity (23.5%) and among employed patients, presenteeism was more frequent than absenteeism (18.5% vs 6.5%). The direct medical costs in this chronic hepatitis C sample was 12,305.72USD per patient in the 2 years study period; drug treatment costs represented 95.9% of this total. CONCLUSION: This study showed that most patients are cirrhotic, present high prevalence of cardiometabolic diseases and esophageal varices, reduced HRQoL mainly in terms of pain/discomfort, and work productivity impairment, especially presenteeism. Additionally, we demonstrated that hepatitis C virus imposes an economic burden on Brazilian Health Care System and that most of this cost is due to drug treatment.
