Chapter of Gastroenterologists professional guidance for management of patients with liver disease in Singapore during the COVID-19 pandemic

In this paper, we aim to provide professional guidance to clinicians who are managing patients with chronic liver disease during the current coronavirus disease 2019 (COVID-19) pandemic in Singapore. We reviewed and summarised the available relevant published data on liver disease in COVID-19 and the advisory statements that were issued by major professional bodies, such as the American Association for the Study of Liver Diseases and European Association for the Study of the Liver, contextualising the recommendations to our local situation.

Case for diagnosis. Sclerodermiform manifestations of porphyria cutanea tarda secondary to hepatitis C

Abstract: A 63-year-old black female patient with blisters and exulcerations on the face, neck, upper limbs, and subsequent evolution with hypochromic sclerotic areas and alopecia, is reported. Chronic hepatitis C and presence of high levels of porphyrins in urine were demonstrated. There was complete remission with the use of hydroxychloroquine, photoprotection, and treatment of hepatitis. Significant sclerodermoid involvement of the skin as a manifestation of porphyria cutanea tarda secondary to hepatitis C emphasizes the importance of diagnostic suspicion regarding skin manifestation in order to indicate the appropriate therapy, and to minimize the hepatic morbidity.

Coût financier de la prise en charge des hépatites virales chroniques B et C au CHU de Brazzaville (Congo)

Introduction. Les dépenses de santé ont considérablement augmenté dans le monde lors de la dernière décennie. Les hépatites virales chroniques B et C sont des affections chroniques nécessitant un traitement prolongé et qui est encore coûteux, le Congo ne disposant pas encore d'assistance maladie universelle. Le but de cette étude était d'évaluer le coût de la prise en charge des hépatites virales B et C au Congo. Matériels et Méthodes. Il s'agit d'une étude transversale rétrospective et descriptive, réalisée du 1er juin au 31 Décembre 2016 dans le service de Gastro-entérologie et médecine interne du CHU de Brazzaville. Nous avons colligé les dossiers des patients suivis pour hépatite B et C. Les variables d'étude ont été les coûts des examens paracliniques et les coûts des traitements. Résultats. les coûts des examens paracliniques étaient de 296 000 FCFA (451€) pour le coût maximum de l'hépatite B, celui de l'hépatite C était de 596 500 FCFA (910,6 €). Les coûts du traitement de l'hépatite virale C étaient de 1 050 000 FCFA (1603,05 €) pour trois mois. Pour l'hépatite B, ils étaient de 389 987 (595,4€) par semestre. Le coût global de la prise de l'hépatite virale C était de 1 345 313 FCFA (2053,9€) et de 535 569 (817,662 €) pour l'hépatite B. Conclusion. Les coûts de la prise en charge des hépatites B et C sont encore trop élevés au Congo. Une prise en charge globale s'avère nécessaire, similaire à celle de l'infection à VIH

Coinfección virus de inmunodeficiencia humana-virus de la Hepatitis C: hacia un nuevo escenario terapéutico / Human Immunodeficiency Virus-Hepatitis C virus coinfection: towards a new therapeutic scenario

Introducción: Las terapias contra el virus de la Hepatitis C han evolucionado vertiginosamente con el desarrollo de los antivirales de acción directa (AADs). Los nuevos regímenes han conseguido igualar las tasas de respuesta al tratamiento en los monoinfectados y los coinfectados con VIH, una población tradicionalmente difícil de tratar debido a la elevada morbimortalidad hepática y sistémica, reacciones adversas e interacciones medicamentosas. Objetivo: Analizar las opciones farmacoterapéuticas más modernas disponibles para los pacientes coinfectados con VIH y VHC, con énfasis en los nuevos antivirales de acción directa, a fin de ofrecer una herramienta útil en el abordaje terapéutico en estos pacientes. Material y métodos: Se revisaron artículos originales, ensayos clínicos y revisiones sistemáticas hasta septiembre de 2016, bases de datos internacionales de interacciones medicamentosas y Guías de Práctica Clínica actualizadas. Desarrollo: Las terapias contra el virus de la Hepatitis C (VHC) han evolucionado vertiginosamente con el desarrollo de los antivirales de acción directa (AADs). Los nuevos regímenes han conseguido igualar las tasas de respuesta al tratamiento en los monoinfectados y los coinfectados con VIH, una población tradicionalmente difícil de tratar que, además, asociaba una elevada morbimortalidad hepática y sistémica, más reacciones adversas y complejas interacciones medicamentosas. Conclusiones: En este nuevo escenario es fundamental dedicar esfuerzos a identificar el elevado porcentaje de infectados no diagnosticados, potenciales interacciones, especialmente con fármacos para patologías asociadas al envejecimiento de los pacientes, reacciones adversas a medio-largo plazos y desarrollo de resistencias, además de garantizar la cobertura universal en todos los contextos clínicos(AU)

Introduction:Therapies for hepatitis C virus (HCV) have rapidly evolved with the development of direct-acting antiviral agents. New regimens, achieve an equate response rates to treatment in cases of HCV mono-infected and HIV/HCV co-infected; a population traditionally difficult to treat due to a high hepatic and systemic morbidity-mortality, adverse reactions and drug interactions. Objective: To analyse the current Pharma-therapeutic options available for co-infected HIV-HCV patients, with emphasis I the new direct-acting antiviral agents, in order to offer a useful tool for the therapeutic approach in these patients. Material and Methods: Original articles, clinical studies and systematic reviews until September 2016 were carried out, as well as international drug interactions databases and updated Practical Guidelines. Development: Therapies for hepatitis C virus (HCV) have rapidly evolved with the development of direct-acting antiviral agents. New regimens achieve an equate response rates to treatment in HCV mono-infected and HIV/HCV co-infected; a population traditionally difficult to treat, which also associate a high hepatic and systemic morbidity-mortality, adverse reactions and complex drug interactions. Conclusions: In this new scenario efforts must be addressed to identify the high percentage of undiagnosed patients; potential interactions, especially with drugs related with patient aging; medium and long-term adverse reactions and development of drug resistances, as well as to guarantee universal coverage in all clinical contexts(AU)

Hematological and dermatological adverse events during hepatitis C treatment with peg-interferon and ribavirin / Eventos adversos hematológicos e dermatológicos durante o tratamento da hepatite C com interferon peguilado e ribavirina

Objective: To evaluate frequency and impact of adverse events, mainly the hematological and dermatological ones, on sustained virological response, and compliance to hepatitis C treatment. Methods: Patients were treated according to the guidelines of the Brazilian Ministry of Health. Variables associated with hematological and dermatological adverse events were: age, gender, stage of fibrosis, type of Pegylated interferon, dose reductions, temporary discontinuation and early interruption of treatment. Results: Two hundred and twenty two patients were studied (58% females; age 49±11 years). Dose reductions, temporary interruptions, and early discontinuations were observed in 21%, 8% and 9.5% of patients, respectively. The main adverse events were hematological (anemia, neutropenia and thrombocytopenia) and dermatological (pruritus and alopecia). Anemia (Hemoglobin <10g/dL) was associated with female gender (p<0.001), advanced fibrosis (p=0.047) and dose reductions (p<0.001); neutropenia with advanced fibrosis (p=0.003) and temporary discontinuation (p=0.002); thrombocytopenia with advanced fibrosis (p<0.001) and pegylated interferon α2a (p=0.05). Pruritus and alopecia were associated to female gender (p=0.008 and p=0.02) and treatment interruption (p=0.029 and p=0.02).Conclusion: Hematological and dermatological adverse events are frequent in hepatitis C patients treated with pegylated interferon and ribavirin. However, despite frequent dose reductions and interruptions, these adverse events did not affect the sustained virological response.

Objetivo: Avaliar a frequência e o impacto de eventos adversos, principalmente hematológicos e dermatológicos, na resposta virológica sustentada e na aderência ao tratamento para hepatite C. Métodos: Os pacientes foram tratados de acordo com diretriz do Ministério da Saúde. Variáveis associadas com eventos adversos hematológicos e dermatológicos foram: idade, sexo, grau de fibrose, tipo de interferon peguilado, reduções de dose, descontinuação temporária e interrupção precoce do tratamento. Resultados: Foram estudados 232 pacientes (58% mulheres; idade 49±11 anos). Reduções de dose, interrupções temporárias e descontinuações precoces foram observadas em 21%, 8% e 9,5% dos pacientes, respectivamente. Os principais eventos adversos foram hematológicos (anemia, neutropenia e plaquetopenia) e dermatológicos (prurido e alopecia). Anemia (hemoglobina <10g/dL) se associou a sexo feminino (p<0,001), fibrose avançada (p=0,047) e reduções de doses (p<0,001); neutropenia com fibrose avançada (p=0,003) e interrupção temporária (p=0,002); plaquetopenia com fibrose avançada (p<0,001) e interferon peguilado α2a (p=0,05). Prurido e alopecia se associaram ao sexo feminino (p=0,008 e p=0,02) e interrupção do tratamento (p=0,029 e p=0,02). Conclusão: Eventos adversos hematológicos e dermatológicos foram frequentes em pacientes tratados com interferon peguilado e ribavirina. Entretanto, a despeito de frequentes reduções de dose e interrupções, estes eventos adversos não afetaram a resposta virológica sustentada.

Hep-net opinion about the management of patients with chronic hepatitis C in Pakistan in the era of available direct acting antivirals

In Pakistan, we have 4.9% prevalence of HCV in general population, with 79% genotype 3. Recently Sofosbuvir has been made available at compassionate price in Pakistan. Management of chronic hepatitis C includes counseling of HCV patients, their proper assessment to select those who need antiviral therapy, initiation of appropriate antiviral agents and duration of therapy, along-with careful monitoring for safety and efficacy. Hepatic status as well as previous history of HCV therapy needs to be taken in the consideration before starting antiviral therapy. Other factors include co-morbid conditions like obesity, DM, NASH, etc. Treatment of special populations like liver transplant patients, patients with HBV co-infection, chronic kidney disease and hemoglobinopathies need special considerations when initiating HCV therapy

Vivências e necessidades de saúde de homens no período pós-nascimento de um filho / Experiences and health needs of men in the period post-birth of a child / Experiencias y necesidades de salud de los hombres en el período post-nacimiento de un hijo

Esta pesquisa aborda percepções de homens sobre suas experiências e necessidades de saúde no pós-nascimento. Objetiva-se distinguir analiticamente, a partir de uma perspectiva de gênero, necessidades de saúde relativas ao evento, experimentadas, expressas e/ou negadas pelos homens. Trata-se de um estudo exploratório-descritivo, qualitativo, realizado em dois territórios de saúde de Cuiabá, Mato Grosso, mediante entrevista semiestruturada e análise temática dos dados. Participaram oito homens que vivenciavam o pós-nascimento de um filho. Estes manifestaram, sobretudo, a necessidade de provimento de segurança financeira à família, destacando também a necessidade de bem estar do filho, acessando o retorno afetivo que a experiência traz. Não se reconheciam com necessidades de saúde no pós-nascimento. O apoio dos serviços locais de saúde é importante para que os homens se percebam na vivência da paternidade e a sua relação com aspectos socioculturais, para que distingam necessidades próprias, valorizem o cuidado de si e adotem uma perspectiva equânime de gênero.

This research addresses men’s perceptions about their experiences and health needs in the post-birth period. The goal is to distinguish analytically and from a gender perspective the health needs related to the event, experienced, expressed and/or denied by men. This is an exploratory, descriptive and qualitative study carried out in two municipal health areas of Cuiabá, state of Mato Grosso, using a semi structured interview and thematic analysis of the data. The participants were eight men who were experiencing the post-birth period of a child. Above all, they expressed the need to provide financial security to the family, emphasizing also the need of their children’s well-being, with the affective return that this experience brings. They did not perceive themselves with health needs during the post-birth period. The support provided by local health services is important so that men can understand the experience of parenthood and its relationship with social and cultural aspects in order to distinguish their own needs, appreciate self-care, and adopt a gender equity perspective.

Esta investigación aborda las percepciones de hombres acerca de sus experiencias y necesidades de salud en el período postparto. El objetivo es distinguir analíticamente, desde una perspectiva de género, las necesidades de salud relacionadas al evento, experimentadas, expresadas y/o negadas por los hombres. Se trata de un estudio exploratorio, descriptivo y cualitativo llevado a cabo en dos áreas municipales de salud de Cuiabá, Estado de Mato Grosso, mediante entrevista semiestructurada y análisis temático de los datos. Participaron ocho hombres que experimentaban el período postparto de un hijo. Ellos expresaron, sobre todo, la necesidad de proveer seguridad económica a la familia, destacando también la necesidad del bienestar de los hijos, con el retorno afectivo que esa experiencia proporciona. No se reconocían con necesidades de salud en el período postparto. El apoyo de los servicios locales de salud es importante para que los hombres entiendan la experiencia de la paternidad y su relación con aspectos socioculturales, para que distingan las necesidades, valoren el cuidado de sí mismos y adopten una perspectiva de equidad de género.

Monitoring Hepcidin Level in Chronic Hepatitis C Virus Patients during Therapy

Introduction and study aim : Egypt has the highest prevalence of hepatitis C in the world estimated about 15. There are several host and viral factors that aid in predicting response to treatment; Hepcidine hormone is being investigated as one of these host factors. The aim of the work is to assess the serum concentration of hepcidin in chronic hepatitis C patients and evaluate any possible association with the viral load during therapy.Patients and methods: This study was carried on 35 chronic HCV patients on peg IFN/ Ribavirin therapy and 15 chronic HCV patients not on therapy as a control group.Hepcidin hormone levels were measured in sera of patients before starting therapy (base line) then at 12 and 24 weeks during therapy. RT PCR was used to asses response to ongoing therapy.Results: The level of hepcidin in all cases was low before starting therapy and it showed a significant increase during the course of therapy. This rise was detected earlier in responding cases. A negative correlation was found between baseline hepcidin level and baseline viral load of the responding cases. Conclusion: Chronic HCV infection is associated with reduced level of serum hepcidin hormone. The reduced serum hepcidin in chronic HCV patients is fully reversible after IFN/RBV therapy. Initial rise in serum hepcidin concentration might have a potential for being used as one of the indicators of patient response to therapy

Nuevos antivirales frente al VHC: actualidad y perspectivas / New direct acting antiviral for hepatitis C: future perspectives

Aproximadamente 175 millones de personas están infectadas por el virus de la hepatitis C (VHC), lo que representa un 3% de la población mundial. En ausencia de tratamiento eficaz, un 25% de los pacientes desarrollan complicaciones hepáticas tras 25 años de hepatitis crónica C. Hasta hace poco, la única opción terapéutica en estos pacientes era la combinación de interferón pegilado (peg-IFN) y ribavirina (RBV). Alcanzaban la erradicación del VHC un 30-40% de los pacientes infectados con el genotipo 1 del VHC. Recientes avances han permitido desarrollar replicones y sistemas de cultivo tisulares para el VHC. Esto ha facilitado el diseño de fármacos antivirales directos (DAA) que inhiben específicamente la replicación del VHC. Los dos primeros inhibidores de la proteasa del VHC fueron aprobados en mayo de 2011. Permiten obtener tasas de curación en el 70% de los pacientes infectados con el genotipo 1 sin experiencia previa a interferón. La respuesta es menor en pacientes con fracasos previos, excepto en los recidivantes, en los que tasa de curación es del 90%...

Approximately 175 million people worldwide are chronically infected with the hepatitis C virus (HCV), representing 3% of the total world population. In the absence of successful therapy nearly 25% of these patients will develop hepatic complications within 25 years. Until recently, the only available therapeutic option for these patients was the combination of peginterferon-a plus ribavirin. Overall it allowed achievement of eradication in only 30-40% of patients infected by HCV genotype 1. The development of HCV replicons and the chance of producing infectious viral particles in culture systems have both enabled the rational design of direct-acting antivirals (DAA) that specifically inhibit HCV replication. The first two HCV protease inhibitors were marketed in May 2011. Triple therapy has increased the response rate to 70% in HCV genotype 1 carrier naïve to interferon. Although response rates are lower in prior failures, 90% sustained virological response rates are achieved in prior relapsers...

Empleo del Interferón alfa 2b recombinante y ribavirina en la lesión hepática crónica producida por virus C en pacientes no respondedores a la monoterapia / Use of recombinant interferon alpha 2b and Ribavirin in chronic liver injury caused by C virus in patients not answering to monotherapy

Se realizó un estudio observacional descriptivo, de corte transversal, con el objetivo de describir los resultados y la tolerabilidad de la terapia combinada con interferón alfa 2b recombinante y ribavirina en el retratamiento de pacientes con lesión hepática crónica causada por el virus de la hepatitis C, se seleccionaron 17 pacientes atendidos en la consulta de Hepatología, del Servicio de Gastroenterología, del Hospital Provincial Docente Dr Antonio Luaces Iraola, que no respondieron a un primer tratamiento con interferón como monoterapia; los datos obtenidos fueron recogidos en la planilla de recolección de datos. Los pacientes con hepatitis crónica C eran mayoritariamente adultos jóvenes y de sexo masculino. Los grupos de población más afectados fueron los pacientes con una conducta sexual de riesgo o desprotegida, los pacientes con antecedentes de atención estomatológica, receptores de transfusiones y el personal sanitario. Se les aplicó una terapia combinada durante 52 semanas, un 58 por ciento de los pacientes estudiados resultaron negativos al final del tratamiento, el 94 por ciento normalizaron la alanino aminotransferasa, se observó una mejoría histológica respecto a la biopsia inicial en la mayoría de los casos, la reacción adversa más frecuente fue el síndrome seudogripal.

A descriptive observational study of cross-section, was conducted with the aim of describing the results and tolerability of combined therapy with recombinant interferon alfa 2b and ribavirin in the re-treatment of patients with injury caused by hepatitis C virus, 17 patients treated in the hepatology consultation,were selected from Gastroenterology Service of Provincial teaching Hospital Dr Antonio Luaces Iraola, that not respond to a first treatment with interferon as monotherapy; the data were obtained in the form of data collection. Patients with chronic hepatitis C were mostly young and male adults. The most affected population groups were patients with unprotected or sexual risk behaviour, patients with a history of stomatological care, blood transfusion receptors and medical personnel. A combined therapy was applied to them for 52 weeks, 58 percent of the studied patients were negative at the end of the treatment, 94 percent normalized Alanine aminotransferase, a histological improvement regarding the initial biopsy in the majority of cases was observed, the most common adverse reaction was the flu syndrome.

Behavior and major barriers faced by non-injectable drug users with HBV/HCV seeking treatment for hepatitis and drug addiction in Rio de Janeiro, Brazil / Comportamentos e barreiras relacionados à busca ao tratamento para a hepatite e dependência química entre usuários de drogas não injetáveis com hepatite crônica do Rio de Janeiro, Brasil

Drug users (DU) are a marginalized group and at risk for viral hepatitis, who seldom access health services. A cross-sectional survey was conducted with 111 DU with chronic HBV/HCV and 15 in-depth interviews with health professionals/policymakers in Rio de Janeiro, Brazil. Most interviewees were male, non-white, with a low educational background, unemployed and/or living on less than $245 a month (minimun wage). In the last 6 months, 61.8 percent of interviewees snorted cocaine, 64.7 percent at least once a week. Half of the interviewees had a stable partner and 38.3 percent of those with occasional partners never/almost never using condoms. Addiction treatment seeking was found to be associated with: being white (OR:5.5), high-school degree (OR:8.7), and employment (OR:5.7). Hepatitis treatment seeking was high (80.9 percent), and access to low-threshold, user-friendly health services was key for treatment seeking behaviors (OR:3.6). Missed opportunities for hepatitis treatment seem to be associated with structural (uneven political/financial support to hepatitis programs) and patient-related barriers (severe addiction and non-adherence). Those most in need were less likely to access treatment, calling for renewed strategies, in order to curb hepatitis among impoverished drug users and their sexual partners.

Usuários de drogas (UD) são uma população marginalizada e sob risco para hepatites virais que raramente acessam tratamento. Foi utilizado inquérito com 110 UD com Hepatite crônica e 15 entrevistas em profundidade com profissionais e gestores de saúde. A maioria dos entrevistados é homem, não branco, com baixa escolaridade, desempregado e com renda < salário mínimo. Nos últimos 6 meses, 61,8 por cento usaram cocaína inalada e 64,7 por cento uma vez por semana ou mais. Dos participantes, 50 por cento tiveram relações sexuais com parceiros estáveis e 38,3 por cento com parceiros ocasionais nunca/quase nunca usando preservativos. Preditores de busca por tratamento para dependência química incluem: raça/cor branca (OR:5.5), ter ensino médio (OR:8.7) e estar empregado (OR:5.7). 80,9 por cento dos participantes buscou tratamento para hepatite, o acesso a serviços mais acolhedores é determinante para esse comportamento (OR:3.6). Oportunidades perdidas para tratamento de hepatite estão associadas a barreiras estruturais (inadequado apoio político/financeiro aos programas) e barreiras individuais (dependência química severa e baixa aderência). Aqueles que mais precisam de tratamento possuem menor chance de obtê-lo, salientando a importância de renovar estratégias para responder à epidemia de hepatite entre usuários de drogas empobrecidos e seus parceiros sexuais.

Infección por virus de la hepatitis C en niños / Hepatitis C virus infection in children

La hepatitis C se adquiere por las vías parenteral, materno-fetal y sexual. Afecta al 3 por ciento de la población mundial. La transmisión vertical constituye la principal forma de diseminación del virus actualmente. La mayoría de los niños desarrolla enfermedad crónica asintomática; sin embargo, puede observarse progresión de la enfermedad en la edad pediátrica. Los anticuerpos contra el virus de la hepatitis C no permiten discriminar entre infección activa y resuelta. Se requiere la determinación por PCR del HCV-ARN. La combinación de peginterferón y ribavirina parece ser el tratamiento más eficaz. El desarrollo de nuevos fármacos, así como el de una vacuna, constituyen los próximos desafíos.

The modes of transmission of hepatitis C virus are parenteral, sexual and maternal-fetal. It affects 3 percent of the population worldwide. Currently, vertical infection is the main way of virus spreading. Most children are clinically asymptomatic, but progression of liver disease has been described. The positivity of antibodies against hepatitis C virus does not discriminate between active and resolved infection, so determination of serum HCV-RNA is necessary. The combination of peginterferon and ribavirin appears to be the most effective treatment. Future challenges are the development of new drugs and a vaccine.

Reflexões sobre o adoecer e mudanças dietéticas durante a assistência nutricional em pacientes com hepatite C / Reflections about getting sick and dietetic changes during nutritional assistance with hepatitis C patients

Trata-se de investigar os significados atribuídos por pacientes portadores do vírus da hepatite C sobre a doença e o tratamento dietético. Para tanto, adota-se a metodologia da pesquisa qualitativa em que o sujeito interage com sua narrativa sobre o objeto de estudo e os pesquisadores analisam cuidadosamente seus enunciados. As acepções sobre o adoecer e as mudanças dos hábitos alimentares e de vida dos pacientes foram analisadas por meio da obtenção de entrevistas em profundidade. Ao trazer os sentidos expressos sobre a doença, cria-se a possibilidade de compreensão dos aspectos culturais sobre a alimentação, a nutrição e a dietética; um desafio para os profissionais de saúde e nutrição, que precisam relatar a seus pacientes a necessidade de seguir hábitos alimentares mais saudáveis, implicando alterações nem sempre simples de serem realizadas. Consideram-se hábitos e representações do ato da alimentação, como parte da identidade cultural do sujeito. Justifica-se este estudo pela necessidade de situar maior interação entre profissionais, estudantes de saúde e pacientes de modo a ampliar a compreensão dos fenômenos que cercam a experiência da doença pelos pacientes. Conclui-se que os pacientes de hepatite C atendidos no ambulatório do Hospital Universitário da cidade de Salvador e o profissional podem atingir os objetivos de aconselhamentos nutricionais, se trilharem direções dialógicas. Com isso, observou-se a adesão à orientação dietética sem rupturas bruscas e sofrimentos dos pacientes.

This paper investigates the meanings attributed by patients to hepatitis C on disease and dietary treatment. To this end, we adopt the methodology of qualitative research in which the individual interacts with his narrative on the subject of study and the researchers carefully examine their statements. The meanings of the illness and changes in dietary habits and life of the patients were analyzed by obtaining in-depth interviews. By bringing the senses expressed about the disease, it creates the possibility of understanding cultural factors on diet, nutrition and dietetics - a challenge for health professionals and nutrition, which need to report their patients the need to follow dietary healthier, involving changes not always simple to perform. Habits and representations of the act of feeding are considered part of the cultural identity of the subject. This study is justified by the need to place greater interaction among professionals, students, patients and health so as to broaden the understanding of the phenomena that surround the experience of illness by patients. We conclude that outpatients with hepatitis C at the University Hospital in the city of Salvador and the professional can achieve the goals of nutritional advice, if they follow dialogic lines. Thus, there was compliance with dietary counseling without sudden breaks and suffering of patients.

Se utilizó interferón a 2b recombinante (3 millones de unidades 3 veces por semana) más ribavirina (1 000 o 1 200 mg diarios en dependencia del peso corporal) durante 48 sem. RESULTADOS: Se obtuvo una tasa de respuesta virológica y bioquímica sostenida a la semana 72 de 32,8 y 50,8 por ciento respectivamente. Un 41,3 por ciento del total de pacientes experimentó mejoría histológica a expensas de la reducción de la fibrosis y pocos cambios en la inflamación. CONCLUSIONES: Teniendo en cuenta la tasa de respuesta global obtenida, se consideró como tratamiento eficaz para la hepatitis crónica C y se recomendó profundizar en el conocimiento de las características de la infección en Cuba así como en opciones de tratamiento más eficaces para esta enfermedad

The hepatitis C virus becomes in leading cause of chronic hepatitis, hepatic cirrhosis, hepatocarcinoma and liver transplant at world level. OBJECTIVE: The aim of present study is to determine the virological, biochemical and histological course of patients presenting with Chronic hepatitis C under a combination of recombinant Interferon alfa-2b plus Ribavirin and to identify the main factors associated with the rates obtained of virological response. METHODS: A non-controlled and multicenter phase IV clinical-therapeutical trial was sponsored by the Institute of Gastroenterology and the Genetics and Biotechnology Engineering Center from May, 2002 to May, 2006. Sample included 122 patients diagnosed with chronic hepatitis C fulfilling the predetermined inclusion and exclusion criteria. Recombinant Interferon alfa-2b (3 millions of t.i.d units) was used plus Ribavirin (1000 or 1200 mg daily depending on the body weight) during 48 weeks. RESULTS: We achieved a sustained biochemical and virological response rate of 32,8 and 50,8 percent, respectively at week 72. A 41,3, percent from the total of patients had a histological improvement at the expense of reduction of fibrosis and a few changes in inflammation level. CONCLUSIONS: Raking into account the global response rate achieved this combined treatment was considered effectiveness for chronic hepatitis C and we recommended to deepen in the knowledge of infection in Cuba, as well as in more efficient treatment options for this disease

Evolución histórica de las terapias antivirales en hepatitis crónica C / Historical course of antiviral therapies in chronic hepatitis C

Dada la creciente incidencia y prevalencia de la infección crónica por el Virus de la hepatitis crónica C, con estimados de infección de alrededor del 3 por ciento de la población mundial, se realizó una revisión bibliográfica sobre los aspectos más relevantes de la evolución histórica que han experimentado las terapias antivirales utilizadas en el tratamiento de esta enfermedad. Se realizó una puesta al día sobre esta temática desde sus orígenes, con especial énfasis en las perspectivas futuras de esta terapéutica, actualmente en estudio por parte de la comunidad científica internacional.

A updating was carried out on this subject matter from its origins with special emphasis on future perspectives of this therapeutics, nowadays under consideration by the international scientific community. For the carrying out of present work 69 bibliographic references were reviewed including the meta-analyses available in MEDLINE from 1998 up to present time, as well as the publications of researches results performed in our country on this subject

need for new anti-hepatitis C virus therapeutic strategies targeting the cellular micro-ribonucleic acids?

Infection with the hepatitis C virus [HCV] is a worldwide problem. Patients with chronic HCV infection who are non-responders to standard therapy represent a growing population within the HCV epidemic.Novel, more efficient and tolerable therapies are urgently needed. This review discusses the recent results showing that targeting miR-122, a micro-ribonucleic acid [MicroRNA] that enhances HCV replication, is a new anti-HCV therapy with a high barrier to resistance
