RESUMO Contexto O transplante renal é o tratamento de escolha para pacientes com doença renal terminal e está associado a menor mortalidade quando comparado aos métodos dialíticos. O Brasil é o país com o segundo maior número de transplantes renais do mundo e, entre esses pacientes, observa-se que as alterações hepáticas são comuns. A frequência das alterações hepáticas varia de 20 a 50% pós-transplante e tem importante impacto na sobrevida e qualidade de vida desses pacientes. Existem poucos dados sobre a frequência, causas e características dessas alterações. Objetivo Determinar a prevalência das diferentes causas de anormalidades hepáticas em receptores de transplante renal, associar as características dessas anormalidades a variáveis demográficas, epidemiológicas e clínicas, comparar as características das alterações hepáticas entre diferentes etiologias e avaliar possíveis alterações no diagnóstico em dois períodos diferentes de tempo. Métodos Estudo epidemiológico descritivo, transversal, observacional, realizado no ambulatório “Hepato-Rim” do Hospital São Paulo (EPM/UNIFESP), centro de atendimento especializado a pacientes com anormalidades hepáticas e doenças renais de base. Resultados Quinhentos e oitenta e um pacientes transplantados foram avaliados. As etiologias mais prevalentes de anormalidades hepáticas foram hepatite C e B, sobrecarga de ferro, doença hepática gordurosa não alcoólica e lesão hepática induzida por drogas. A causa mais comum — hepatite C — foi analisada em maiores detalhes. Em comparação com as outras causas, essa infecção foi a mais frequente em pacientes mais velhos, pacientes do sexo feminino e pacientes com mais tempo de transplante e hemodiálise. A análise dos dois períodos mostrou que os pacientes do período 1 (P1 — 1993 a 2005) eram mais velhos e encaminhados com maior frequência devido à sorologia positiva; encaminhamento devido a anormalidades de aminotransferases predominou durante o período 2 (P2 — 2006 a 2018). Os diagnósticos predominantes foram hepatite C e B durante P1 e doença hepática gordurosa não alcoólica e lesão hepática induzida por drogas durante P2. Conclusão A avaliação das principais alterações hepáticas em receptores de transplante renal é importante, pois permite melhor manejo desses pacientes na investigação diagnóstica e no tratamento e contribui para a prevenção de complicações nesta população especial.

ABSTRACT Background Kidney transplant is the treatment of choice for patients with end-stage renal disease and is associated with lower mortality when compared to dialysis methods. Brazil is the country with the second largest number of kidney transplants in the world and among these patients it has been observed that liver abnormalities are common. The frequency of liver abnormalities ranges from 20-50% post-transplantation, and have an important impact on the survival and quality of life of these patients. There are scarce data about the frequency, causes and characteristics of these alterations. Objective To determine the prevalence of the different causes of hepatic abnormalities in kidney transplant recipients, to associate the characteristics of these abnormalities with demographic, epidemiological and clinical variables, to compare the characteristics of hepatic alterations between different etiologies, and to evaluate possible changes in diagnosis over two different periods of time. Methods Descriptive, cross-sectional observational, epidemiological study was conducted at the outpatient “Hepato-Rim”clinic of Hospital São Paulo (EPM/UNIFESP), a center providing specialized care for patients with hepatic abnormalities and underlying kidney diseases. Results Five-hundred eighty-one transplant patients were evaluated. The most prevalent etiologies of liver abnormalities were hepatitis C and B, iron overload, nonalcoholic fatty liver disease (NAFLD), and drug-induced liver injury (DILI). The most common cause — hepatitis C — was analyzed in greater detail. Compared to the other causes, this infection was more frequent in older patients, female patients, and patients with a longer time since transplantation and hemodialysis. Analysis of the two periods showed that patients of period 1 (P1 — 1993 to 2005) were older and were more frequently referred because of positive serology; referral due to aminotransferases abnormalities predominated during period 2 (P2 — 2006 to 2018). The predominant diagnoses were hepatitis C and B during P1 and NAFLD and DILI during P2. Conclusion Assessment of the main hepatic alterations in kidney transplant recipients is important because it permits better management of these patients in terms of diagnostic investigation and treatment and contributes to the prevention of complications in this special population.

ABSTRACT BACKGROUND: Although autonomic dysfunction has been shown to be associated with liver cirrhosis, the prevalence and prognostic implications are unclear. Abnormal heart rate variability (HRV), a measure of autonomic function, has not been well investigated in cirrhosis. OBJECTIVE: To evaluate the prevalence of high-risk HRV parameters in a cohort of cirrhotic patients and their association with cardiac dysfunction and mortality. DESIGN AND SETTING: Prospective observational study conducted in the Federal University of São Paulo. METHOD: A cohort of 120 patients, comprising 17 healthy controls and 103 cirrhotic outpatients, was evaluated and followed for 10 months. HRV analysis was based on 24-hour Holter monitoring and defined using time-domain and frequency-domain parameters. RESULTS: The HRV parameters were statistically lower in cirrhotic patients than in healthy subjects. High-risk HRV parameters were prevalent, such that 64% had at least one high-risk parameter. Time-domain parameters correlated with Child scores (P < 0.0001). In regression models, HRV parameters were independent predictors of diastolic dysfunction and mortality. During 10 months of follow-up, there were 11 deaths, all of patients with at least one high-risk HRV parameter. Kaplan-Meier analysis estimated low survival rates among patients with standard deviation of normal-to-normal RR intervals (SDNN) < 100. CONCLUSION: Reduced HRV is prevalent in liver cirrhosis and is related to cardiac dysfunction, severity of liver disease and mortality. Abnormal high-risk HRV parameters are prevalent among cirrhotic patients and are also predictors of mortality. Our findings highlight the need for a more careful cardiac evaluation of cirrhotic patients.

ABSTRACT Introduction: Hepatitis C virus (HCV) infection continues to be an important public health problem worldwide. Despite the availability of drugs that promote the cure of infection in more than 95% of cases, the identification of HCV carriers remains a major challenge. Objective: To evaluate a strategy for identifying HCV carriers based on combined criteria: screening in emergency units and specialty outpatient clinics of a tertiary hospital and among older adults (≥45 years), both suggested as efficient in epidemiological studies. Methods: A cross-sectional, analytical and descriptive study was conducted on individuals of both sexes, aged 45 years and older, attending the emergency department and specialty outpatient clinics of a University Hospital in São Paulo, Brazil, from January 2016 to June 2018. After giving formal consent, the patients were submitted to a standardized interview and rapid testing for the identification of HCV antibodies (SD BIOLINE® anti-HCV). Results: A total of 606 adult patients (62% women and 37% men) were evaluated. The mean age was 62 ± 10 years. Four positive tests were identified, with confirmation by conventional serology and HCV-RNA determination. Thus, the prevalence of HCV identified in the sample was 0.66%. All patients had a history of risk factors for infection. Conclusion: The strategies of birth-cohort testing and screening in emergency medical services for the identification of HCV carries, both suggested in the literature as efficient for the diagnosis of hepatitis C, resulted in a low rate of HCV infection. These findings highlight the magnitude of the challenge of identifying asymptomatic HCV carriers in Brazil.

Abstract Chronic hepatitis B is an important health problem that can progress to cirrhosis and complications such as hepatocellular carcinoma. There is approximately 290 million of people with chronic hepatitis B virus (HBV) infection worldwide, however only 10% of patients are currently identified.Most part of Brazil is considered of low prevalence of HBV infection but there are some regions with higher frequency of carriers. Unfortunately, many infected patients are not yet identified nor evaluated for treatment.The Brazilian Society of Infectious Diseases (SBI) and the Brazilian Society of Hepatology worked together to elaborate a guideline for diagnosis and treatment of hepatitis B. The document includes information regarding the population to be tested, diagnostic tools, indications of treatment, therapeutic schemes and also how to handle HBV infection in specific situations (pregnancy, children, immunosuppression, etc).Delta infection is also part of the guideline, since it is an important infection in some parts of the country.

RESUMO CONTEXTO: Os antivirais de ação direta revolucionaram o tratamento da hepatite C, inclusive para os pacientes com doença renal crônica (DRC), porém ainda há divergências no emprego do sofosbuvir (SOF) quando taxa de filtração glomerular (TFG) <30 mL/min. OBJETIVO: Avaliar a eficácia e segurança desses esquemas no tratamento da hepatite C em pacientes com DRC e pós-transplante renal, além de avaliar o impacto do SOF sobre a função renal dos não-dialíticos. MÉTODOS: Todos os pacientes com hepatite C e DRC ou transplante renal que realizaram tratamento com antivirais de ação direta em centro referenciado do Brasil no período de janeiro/2016 a agosto/2017 foram incluídos. A eficácia foi avaliada por meio da carga viral (HCV-RNA), considerando-se cura uma resposta virológica sustentada (RVS) com resultado indetectável após 12 e/ou 24 semanas do término do tratamento (RVS12 e RVS24). A segurança foi determinada pelos eventos adversos e a ribavirina, quando associada, foi introduzida de forma escalonada em todos os pacientes com TFG <60 mL/min. Para determinação do impacto do SOF sobre a função renal, foram observadas as dosagens de creatinina basal, durante e após término do tratamento com seu incremento avaliado por meio da classificação de AKIN (acute kidney injury network). RESULTADOS: Foram incluídos 241 pacientes, sendo 52,7% do sexo feminino, com média de idade de 60,72±10,47 anos. A associação de SOF+daclatasvir predominou em 75,6% dos casos e anemia esteve presente em 28% dos pacientes que utilizaram ribavirina (P=0,040). As taxas de RVS12 e RVS24 foram de 99,3% e 97,1%. O tratamento foi bem tolerado, com eventos adversos pouco relevantes, sendo os mais prevalentes: astenia (57,7%), prurido (41,1%), cefaleia (40,7%) e irritabilidade (40,2%). Entre os pacientes em tratamento conservador e transplantados renais, os valores de creatinina sofreram oscilações AKIN I em 12,5% dos casos, durante o tratamento, persistindo em apenas 8,5% da amostra após o término, dos quais 2,0% apresentavam TFG <30 mL/min inicialmente, com queda para 1,1% após uso do SOF. Apenas 0,5% e 1,6% evoluíram com elevação AKIN II e AKIN III. CONCLUSÃO: Os antivirais de ação direta foram seguros e eficazes em pacientes com DRC tratados com esquemas contendo SOF, apresentando altas taxas de RVS, boa tolerabilidade e poucos eventos adversos graves. A associação com ribavirina aumentou o risco de anemia, portanto sua introdução de forma escalonada parece ser útil nos pacientes com TFG <60 mL/min. Em pacientes com TFG <30 mL/min o SOF não apresentou impacto renal significativo, com creatinina sérica retornando a valores próximos ao basal após o tratamento.

ABSTRACT BACKGROUND: Direct-acting antivirals have revolutionized hepatitis C treatment, also for patients with chronic kidney disease (CKD), but some controversy exists regarding the use of sofosbuvir (SOF) in patients with glomerular filtration rate (GFR) <30 mL/min. OBJECTIVE: To evaluate the efficacy and safety of these regimens for hepatitis C treatment of patients with CKD and after renal transplantation, as well as the impact of SOF on renal function in non-dialysis patients. METHODS: All patients with hepatitis C and CKD or renal transplant treated with direct-acting antivirals at a referral center in Brazil between January 2016 and August 2017 were included. Efficacy was evaluated based on viral load (HCV RNA) and a sustained virological response (SVR) consisting of undetectable RNA 12 and/or 24 weeks after the end of treatment (SVR12 and SVR24) was defined as cure. Safety was determined by adverse events and ribavirin, when combined, was administered in escalating doses to all patients with GFR <60 mL/min. The impact of SOF on renal function was determined by the measurement of baseline creatinine during and after the end of treatment and its increase was evaluated using the Acute Kidney Injury Network (AKIN) classification. RESULTS: A total of 241 patients (52.7% females) with a mean age of 60.72±10.47 years were included. The combination of SOF+daclatasvir was the predominant regimen in 75.6% of cases and anemia was present in 28% of patients who used ribavirin (P=0.04). The SVR12 and SVR24 rates were 99.3% and 97.1%, respectively. The treatment was well tolerated and there were no major clinically relevant adverse events, with the most prevalent being asthenia (57.7%), itching (41.1%), headache (40.7%), and irritability (40.2%). Among conservatively treated and renal transplant patients, oscillations of creatinine levels (AKIN I) were observed in 12.5% of cases during treatment and persisted in only 8.5% after the end of treatment. Of these, 2.0% had an initial GFR <30 mL/min and this percentage decreased to 1.1% after SOF use. Only 0.5% and 1.6% of the patients progressed to AKIN II and AKIN III elevation, respectively. CONCLUSION: The direct-acting antivirals were safe and efficacious in CKD patients treated with SOF-containing regimens, with the observation of high SVR rates, good tolerability and few severe adverse events. The combination with ribavirin increased the risk of anemia and the administration of escalating doses seems to be useful in patients with GFR <60 mL/min. In patients with GFR <30 mL/min, SOF had no significant renal impact, with serum creatinine returning to levels close to baseline after treatment.

ABSTRACT Objective Identifying studies that performed screening for hepatitis C and that also assessed the virus prevalence in urgency and emergency unit users. Method A systematic review performed on the LILACS, MEDLINE databases via PubMed, SciELO and Virtual Health Library. Results After careful search and analysis, 19 publications were part of the results, in compliance with the pre-defined criteria. Publication dates were concentrated between 1992 and 2018. The main journal to publish such articles was the Annals of Emergency Medicine (26.31%). Regarding the origin of publications, the following stand out: United States (63.15%), Europe (31.57%), and Asia (5.28%). Regarding prevalence, in the United States, a variation between 1.4% to 18% was observed. In Europe, in turn, the prevalence ranged from 0 to 5%. In the Asian study, the prevalence was 1.8%. Conclusion The screening performed in urgent and emergency units proved to be efficient in identifying new cases, especially when associated with the age factor, which proves to be superior to the strategy based only on risk factors. Thus, for greater effectiveness, the association of three strategies is recommended: screening location, age group, and risk factors.

Resumo De acordo com os dados do último censo da Sociedade Brasileira de Nefrologia (SBN), a prevalência de portadores do vírus da hepatite C (HCV) nas unidades de hemodiálise (UH) no Brasil é de 3,3%, cerca de três vezes maior do que é observado na população geral brasileira. Muitas vezes, os profissionais que trabalham nas UH deparam-se com situações clínicas que demandam rápido diagnóstico do HCV, a fim de evitar uma transmissão horizontal dentro das unidades. Por outro lado, a cura dos pacientes portadores do HCV, tanto na população geral como na portadora de doença renal crônica e a erradicação da doença, em virtude do desenvolvimento de novas drogas antivirais, parecem ser objetivos bastante factíveis, a ser alcançados em futuro próximo. Nesse cenário, a SBN e a Sociedade Brasileira de Hepatologia apresentam neste artigo de revisão uma proposta de abordagem do HCV dentro das UH.

Abstract According to data from the last census of the Brazilian Society of Nephrology (SBN), the prevalence of hepatitis C virus (HCV) in Brazilian hemodialysis units (HU) is 3.3%, about three times higher than what is reported for the Brazilian general population. Often, professionals working in HU are faced with clinical situations that require rapid HCV diagnosis in order to avoid horizontal transmission within the units. On the other hand, thanks to the development of new antiviral drugs, the cure of patients with HCV, both in the general population and in patients with chronic kidney disease and the disease eradication, appear to be very feasible objectives to be achieved in the near future . In this scenario, SBN and the Brazilian Society of Hepatology present in this review article a proposal to approach HCV within HUs.

ABSTRACT Objective: To evaluate the degree of satisfaction and the socioeconomic profile of patients attending Gastroenterology Outpatient Clinics at a University institution linked to the Brazilian Unified Health System. Method: A researcher-administered questionnaire was applied during a structured interview in outpatient clinics. Results: Two hundred and forty (240) patients were included in the study (mean age of 53 years, 55% women). About 30% of the patients had incomplete elementary education, 25% had complete secondary education, and 53% were active workers. Approximately 87% attending the outpatient clinics were from the B2, C1 and C2 socioeconomic classes with an estimated family income of USD$275.00 to USD$825.00/month. Ninety-two percent (92%) of patients were satisfied with the care received; the items associated with a lower degree of satisfaction were facilities/comfort, cleanliness, and waiting time for consultation. No relationship was observed between socioeconomic profile and degree of satisfaction. Conclusion: Satisfaction surveys are important to identify opportunities for improving healthcare services, and it is incumbent upon managers, health professionals and even users to promote compliance with laws and decrees that seek to improve healthcare.

ABSTRACT Introduction and aim: Hepatitis C is a key challenge to public health in Brazil. The objective of this paper was to describe the Brazilian strategy for hepatitis C to meet the 2030 elimination goal proposed by World Health Organization (WHO). Methods: A mathematical modeling approach was used to estimate the current HCV-infected Brazilian population, and to evaluate the relative costs of two different scenarios to address HCV disease burden in Brazil: (1) if no further changes are made to the HCV treatment program in Brazil; (2) where the WHO targets for 2030 elimination are met through diagnosis and treatment efforts peaking before 2024. Results: An anti-HCV prevalence of 0.53% was calculated for the total population. It was estimated that the number of HCV-RNA+ individuals in Brazil in 2017 was 632,000 (0.31% of the population). Scale-up of treatment and diagnosis over time will be necessary in order to achieve WHO targets beginning in 2018. Direct costs (diagnostic, treatment and healthcare costs) are projected to increase significantly during the scale-up of treatment and diagnosis in the initial years of the intervention scenario, but then fall below the base case on an annual basis by 2025-2036, once HCV is eliminated, due to health sectors savings from the prevention of HCV liver-related morbidity and mortality. Conclusion: Achieving the WHO targets is technically feasible in Brazil with a scale-up of treatment and diagnosis over time, beginning in 2018. However, elimination of hepatitis C requires policy changes to substantially scale-up prevention, screening and treatment of HCV, together with public health advocacy to raise awareness among affected populations and healthcare providers.

OBJECTIVE: To evaluate the effectiveness and safety of first-generation protease inhibitors for the treatment of genotype 1 hepatitis C virus-infected patients at Brazilian reference centers. METHODS: This multicenter cross-sectional study included hepatitis C virus genotype 1 monoinfected patients treated with Peg-interferon, ribavirin, and either boceprevir (n=158) or telaprevir (n=557) between July 2013 and April 2014 at 15 reference centers in Brazil. Demographic, clinical, virological, and adverse events data were collected during treatment and follow-up. RESULTS: Of the 715 patients, 59% had cirrhosis and 67.1% were treatment-experienced. Based on intention-to-treat analysis, the overall sustained viral response was 56.6%, with similar effectiveness in both groups (51.9% for boceprevir and 58% for telaprevir, p=0.190). Serious adverse events occurred in 44.2% of patients, and six deaths (0.8%) were recorded. Cirrhotic patients had lower sustained viral response rates than non-cirrhotic patients (46.9% vs. 70.6%, p<0.001) and a higher incidence of serious adverse events (50.7% vs. 34.8%, p<0.001). Multivariate analysis revealed that sustained viral response was associated with the absence of cirrhosis, viral recurrence after previous treatment, pretreatment platelet count greater than 100,000/mm3, and achievement of a rapid viral response. Female gender, age>65 years, diagnosis of cirrhosis, and abnormal hemoglobin levels/platelet counts prior to treatment were associated with serious adverse events. CONCLUSION: Although serious adverse events rates were higher in this infected population, sustained viral response rates were similar to those reported for other patient cohorts.

Abstract Brazil is one of the 22 countries that concentrates 80% of global tuberculosis cases concomitantly to a large number of hepatitis C carriers and some epidemiological risk scenarios are coincident for both diseases. We analyzed tuberculosis cases that occurred during α-interferon-based therapy for hepatitis C in reference centers in Brazil between 2001 and 2012 and reviewed their medical records. Eighteen tuberculosis cases were observed in patients submitted to hepatitis C α-interferon-based therapy. All patients were human immunodeficiency virus-negative. Nine patients (50%) had extra-pulmonary tuberculosis; 15 (83%) showed significant liver fibrosis. Hepatitis C treatment was discontinued in 12 patients (67%) due to tuberculosis reactivation and six (33%) had sustained virological response. The majority of patients had a favorable outcome but one died. Considering the evidences of α-IFN interference over the containment of Mycobacterium tuberculosis, the immune impairment of cirrhotic patients, the increase of tuberculosis case reports during hepatitis C treatment with atypical and severe presentations and the negative impact on sustained virological response, we think these are strong arguments for latent tuberculosis infection screening before starting α-interferon-based therapy for any indication and even to consider IFN-free regimens against hepatitis C when a patient tests positive for latent tuberculosis infection.

Contexto - Diferentes fatores são responsáveis pela progressão da fibrose na infecção crônica pelo vírus da hepatite C, mas o papel dos fatores nutricionais na progressão da doença não está definido. Este estudo teve como objetivo avaliar o estado nutricional e o perfil dietético de pacientes com hepatite C crônica candidatos a tratamento e sua associação com achados histopatológicos. Métodos - Foi conduzido um estudo transversal em pacientes com hepatite C crônica genótipo 1 virgens de tratamento, entre 2011 e 2013. Foram analisados, antes do tratamento, os seguintes aspectos: biópsia hepática, medidas antropométricas e análise qualitativa e quantitativa do consumo alimentar. Resultados - Setenta pacientes foram estudados. A maioria dos pacientes apresentava obesidade (34%) ou sobrepeso (20%) de acordo com índice de massa corporal e risco para doenças cardiovasculares de acordo com a circunferência da cintura elevada (79%). Na análise qualitativa do consumo alimentar, 59% apresentavam uma dieta inadequada. Conforme análise quantitativa, 59% tinham consumo insuficiente de calorias, 36% consumo excessivo de proteínas e 63% consumo excessivo de gorduras saturadas. Com relação à histologia, 68% apresentavam grau de atividade inflamatória ≥2, 65% mostraram esteatose hepática e 25% possuíam grau de fibrose >2. Na análise comparativa entre as medidas antropométricas e achados histológicos, somente a circunferência da cintura elevada mostrou associação com esteatose hepática ( P =0,05). Não houve associação entre consumo alimentar qualitativo e quantitativo com parâmetros histológicos. Conclusão - A maioria dos pacientes apresentava consumo alimentar inadequado de acordo com parâmetros qualitativos e consumo excessivo de gordura saturada, além de excesso de gordura abdominal, que esteve associada à esteatose hepática. Portanto, aconselhamento nutricional deveria ser implementado em pacientes candidatos a tratamento para hepatite C crônica visando evitar distúrbios nutricionais que podem impactar negativamente no manejo dos pacientes.

Background - Different factors are responsible for the progression of hepatic fibrosis in chronic infection with hepatitis C virus, but the role of nutritional factors in the progression of the disease is not clearly defined. This study aimed to evaluate the nutritional status and dietary profile among patients with chronic hepatitis C who were candidates for treatment and its association with histopathological features. Methods - A crossectional study was conducted on treatment-naïve patients with chronic hepatitis C genotype 1, between 2011 and 2013. The following assessments were performed before treatment: liver biopsy, anthropometric measurements and qualitative/quantitative analysis of food intake. Results - Seventy patients were studied. The majority of patients was classified as obese (34%) or overweight (20%) according to body mass index [BMI] and as at risk for cardiovascular diseases by waist circumference (79%). Unhealthy food intake was presented by 59% according to qualitative parameters and several patients showed an insufficient intake of calories (59%), excessive intake of protein (36%) and of saturated fat (63%), according to quantitative analysis. With respect to histology, 68% presented activity grade ≥2, 65% had steatosis and 25% exhibited fibrosis stage >2. Comparative analysis between anthropometric parameters and histological features showed that elevated waist circumference was the only variable associated to hepatic steatosis ( P =0.05). There was no association between qualitative and quantitative food intake parameters with histological findings. Conclusion - In this study, most of the patients with hepatitis C presented inadequate qualitative food intake and excessive consumption of saturated fat; in addition, excess of abdominal fat was associated to hepatic steatosis. Therefore, nutritional guidance should be implemented prior to treatment in patients with chronic hepatitis C, in order to avoid nutritional disorders and negative impact on the management of patients.

ABSTRACTIn coinfected HBV/HCV patients, HBV replication is usually suppressed by HCV over the time. No study to date has evaluated the HBV viremia in long-term follow-up after HCV treatment in hemodialysis patients with HBV/HCV coinfection. This study aimed to assess the evolution of HBV viremia after HCV treatment in this special population. Ten hemodialysis patients with HBV/HCV coinfection with dominant HCV infection (HBV lower than 2000 IU/mL) and significant fibrosis were treated with interferon-alpha 3 MU 3×/week for 12 months and could be followed for at least 36 months after HCV treatment. Six cases of HBV reactivation (60%) during follow-up were observed and 5/6 had been successfully treated for HCV. Patients with HBV reactivation received anti-HBV therapy. Our preliminary findings indicate that treatment of hepatitis C in HBV/HCV coinfected hemodialysis patients may favor HBV reactivation. Thus, continued monitoring of HBV viremia must be recommended and prompt anti-HBV therapy should be implemented.
