Abstract
- BackgroundTreatment of hepatitis C virus infection in post-transplantation patients is a challenge due to poor tolerance and low success rates.ObjectiveTo determine the response rate to pegylated interferon and ribavirin in post-liver transplant patients with hepatitis C recurrence.MethodsBetween 18 May 2002 and 18 December 2011, 601 patients underwent liver transplantation at our service (Hospital Universitário Walter Cantídio, University of Ceará), 176 (29.2%) of whom were hepatitis C virus positive. Forty received antiviral therapy and were included in this cohort study. Twenty-eight (70%) completed the treatment protocol, which consisted of pegylated interferon and ribavirin for 48 weeks.ResultsThe sustained virological response rate was 55% according to intention-to-treat analysis. Recipient age and exposure to antiviral drugs prior to liver transplantation were associated with sustained virological response in the multivariate analysis. Patients were followed for 57 months on the average. Survival at 1 and 5 years was 100% in responders, versus 100% and 78%, respectively, in non-responders.ConclusionSustained virological response rates were satisfactory in our series of liver transplantation patients, and decreased with increasing recipient age. Non-exposure to antiviral drugs prior to liver transplantation was positively associated with sustained virological response. The overall survival of responders and non-responders was similar. ContextoO tratamento da infecção do vírus da hepatite C pós-transplante é um desafio devido à baixa tolerância dos pacientes e às baixas taxas de resposta.ObjetivoDeterminar a taxa de resposta ao interferon peguilado e ribavirina no tratamento da recorrência da hepatite C após transplante de fígado.MétodosEntre 18 de maio de 2002 e 18 de dezembro de 2011, 601 pacientes realizaram transplante hepático no Hospital Universitário Walter Cantídio, 176 (29,2%) desses eram infectados pelo vírus da hepatite C. Quarenta pacientes receberam terapia antiviral e foram incluídos nesse estudo. Vinte e sete (70%) completaram o protocolo de tratamento, que consistia de interferon peguilado e ribavirina por 48 semanas.ResultadosA taxa de resposta virológica sustentada foi de 55% de acordo com a análise por intenção de tratar. A idade dos receptores e a exposição prévia ao transplante de antivirais foram fatores associados com a resposta virológica sustentada na análise multivariada. Pacientes foram acompanhados por 57 meses em média. A sobrevida em 1 e 5 anos foi de 100% em respondedores, enquanto que em não respondedores foi de 100% e 78% respectivamente.ConclusãoA resposta virológica sustentada foi satisfatória na série de pacientes transplantados e diminuiu com o aumento da idade. A não exposição prévia ao transplante a drogas antivirais teve impacto positivo na chance de resposta virológica sustentada. A sobrevida global foi similar em respondedores e não respondedores.
