Weight-based combination therapy with peginterferon alpha-2b and ribavirin for Naïve, relapser and non-responder patients with chronic hepatitis C

Combination therapy with pegylated interferon and ribavirin is considered the new standard therapy for naïve patients with chronic hepatitis C. We evaluated the efficacy and safety of treatment with weight-based peginterferon alpha-2b (1.5 mg/kg per week) plus ribavirin (800-1,200 mg/day) for 48 weeks in naïve, relapser and non-responder (to previous treatment with interferon plus ribavirin) patients with chronic hepatitis C. Sixty-seven naïve, 26 relapser and 40 non-responder patients were enrolled. The overall sustained virological response (SVR) for the intention-to-treat population was 54 percent for naïve, 62 percent for relapser and 38 percent for non-responder patients. In the naïve subgroup, SVR was significantly higher in patients with the non-1 genotype (67 percent) compared to those with genotype 1 (45 percent). In relapsers and non-responders, SVR was, respectively, 69 percent and 24 percent in patients with genotype 1 and 43 percent and 73 percent in those with genotype non-1. There were no significant differences in SVR rates among the three body weight ranges (< 65 kg, 65-85 kg and > 85 kg) in any of the subgroups. Early virological response (EVR) was reached by 78 percent, 81 percent and 58 percent of naïve, relapser and non-responder patients, respectively, and among those with EVR, 63 percent, 67 percent and 61 percent, respectively, subsequently achieved SVR. All of the non-responder patients who did not have EVR reached SVR. Treatment was discontinued in 13 percent of the patients, due to loss to follow-up, hematological abnormalities or depression.

Prevalence of oral lichen planus in Brazilian patients with HCV infection.

OBJECTIVE: The objective of this investigation was to assess the prevalence of oral lichen planus (OLP) in Brazilian patients infected with hepatitis C virus (HCV) from the state of Rio de Janeiro. STUDY DESIGN: The study group consisted of 134 patients with HCV infection. The control group consisted of 95 individuals. All patients were physically examined for evidence of OLP. The diagnosis of OLP was established on the basis of usual clinical features and histological findings. RESULTS: The prevalence of OLP was 1.5% in patients with HCV infection and 1.1% in the control group. There was no statistically significant difference between the 2 groups (P = .63). CONCLUSION: Our findings indicate that there is no association between OLP and HCV infection in Brazilian patients from the state of Rio de Janeiro.

Tratamento da hepatite C com fator promotor do crescimento do hepatócito (phgf) / Treatment of hepatitis C with promoting hepatocyte growth factor

Em 1987, pesquisadores chineses do Hospital da Força Aérea,localizado em Guangzhou, China, extraíram do fígado de porco recém-nato uma substância denominada promoting hepatocyte growth factor (phgf), que funcionaria como um estimulador do crescimento do hepatócito. Para tanto, agiria no DNA do hepatócito, promovendo síntese e divisão celular, com efeitos antifibrose e antiinflamatório. Investigações recentes sugerem que o phgf possa agir no tratamento das hepatites virais. Desenvolveu-se estudo randomizado e controlado do uso intravenoso do phgf em 18 pacientes com diagnóstico histólogico de hepatite crônica ativa ou cirrose hepática em atividade e RNA-VHC positivo. Todos os pacietes apresentavam aumento da ALT por um período mínimo de 12 meses. Outras causas de hepatopatia foram afastadas (viral, auto-imune, medicamentosa, metabólica e alcoólica). O estudo foi aprovado pela Comissão de Ética do Hospital Universitário Clementino Fraga Filho, Rio de Janeiro. O tratamento foi instituído durante três meses e, mensalmente, eram tomadas amostras de sangue para análise do hemograma, leucograma, contagem de plaquetas, TAP e dosagem da ALT. Determinações de carga viral antes e no final do tratamento foram feitas pelo teste Amplicor HCV Monitor-Roche. Todos os pacientes finalizaram o tratamento, sem a ocorrência de efeitos colaterais atribuíveis à medicação. Em três pacientes a ALT normalizou-se durante o uso de phgf(16,9por cento), com retorno aos valores basais pré-tratamento após a sua interrupção. Porém, em relação ao grupo controle, os valores da ALT diminuiram sensivelmente no grupo tratado, com significância estatística. Apesar de a análise média da carga viral ter mostrado nítica diminuição, estatisticamente significativa no grupo que utilizou o phgf, nenhum paciente tratado apresentou negativação do RNA-VHC. Os resultados mostram que a ação do phgf se fez no processo inflamatório sem influir na replicação viral, sugerindo efeito um pouco semelhante ao da ribavirina
