Hand-foot syndrome due to hepatitis C therapy

SUMMARY INTRODUCTION Direct-acting antivirals are new drugs for chronic hepatitis C treatment. They are usually safe and well tolerated, but can sometimes cause serious adverse effects and there is no consensus on how to treat or prevent them. We described a case of hand-foot syndrome due to hepatitis C virus interferon-free therapy. METHODS We report the case of a 49-year-old man with compensated liver cirrhosis due to chronic hepatitis C genotype 1, treatment-naïve, who started viral treatment with sofosbuvir, simeprevir and ribavirin for 12 weeks. RESULTS At the sixth week of treatment he had anemia, requiring a lower dose of ribavirin. At the tenth week, he had erythematous, pruritic, scaly and flaky lesions on hands and feet, which showed a partial response to oral antihistamines and topical corticosteroids. It was not necessary to discontinue antiviral treatment, but in the first week after the end of treatment, there was worsening of injuries, including signs of secondary infection, that required hospitalization, antibiotics and oral corticosteroid, with progressive improvement. Biopsy of the lesions was consistent with pharmacodermia. The patient had sustained a virological response, despite the side effect. He had a history of pharmacodermia one year ago attributed to the use of topiramate, responsive to oral corticosteroid. CONCLUSION Interferon-free therapies can rarely lead to severe adverse reactions, such as skin lesions. Patients receiving ribavirin combinations and those who had a history of pharmacodermia or skin disease may be more susceptible. There is no consensus on how to prevent skin reactions in these patients.

RESUMO INTRODUÇÃO Antivirais de ação direta são as novas drogas utilizadas no tratamento da hepatite C crônica. São geralmente seguros, com boa tolerância, mas eventualmente podem causar efeitos adversos graves, e não há consenso sobre como tratá-los ou preveni-los. Descrevemos um caso de síndrome mão-pé secundária à terapia livre de interferon para hepatite C crônica. Materiais e métodos Relatamos o caso de um paciente de 49 anos com cirrose hepática compensada secundária à hepatite C crônica, genótipo 1, virgem de tratamento, que iniciou terapia com sofosbuvir, simeprevir e ribavirina por 12 semanas. Resultados Na sexta semana de tratamento, apresentou anemia, sendo necessária redução de dose da ribavirina. Na 20a semana, apresentou lesões eritematosas e descamativas, com prurido em mãos e pés, que teve resposta parcial ao uso de anti-histamínico oral e corticoide tópico. Não foi necessário descontinuar os antivirais, mas na primeira semana após o término do tratamento, houve piora das lesões, com sinais de infecção secundária, sendo necessárias hospitalização e terapia com antibiótico e corticoide oral, com melhora progressiva. Biópsias das lesões foram compatíveis com farmacodermia. O paciente teve resposta virológica sustentada, apesar dos efeitos adversos. Tinha história de farmacodermia há um ano, atribuída ao uso de topiramato, responsiva a corticoterapia oral. Conclusão Os tratamentos livres de interferon raramente causam eventos adversos graves, como lesões cutâneas. Pacientes em uso de ribavirina e com história de farmacodermia ou doença cutânea prévia podem ser mais susceptíveis. Não existe consenso sobre como prevenir reações cutâneas nesses pacientes.

Retrospective analysis of hepatitis B virus chronic infection in 247 patients: clinical stages, response to treatment and poor prognostic factors

Abstract Background: Chronic hepatitis B is a major cause of cirrhosis, and the natural history of the disease has several clinical stages that should be thoroughly understood for the implementation of proper treatment. Nonetheless, curing the disease with antiviral treatment remains a challenge. Aims: To describe the clinical course, response to treatment, and poor prognostic factors in 247 hepatitis B virus chronic infection patients treated in a tertiary hospital in Brazil. Methods: This was a retrospective and observational study, by analyzing the medical records of HBV infected patients between January 2000 and January 2015. Results: Most patients were male (67.2%) and 74.1% were HBeAg negative. Approximately 41% had cirrhosis and 8.5% were hepatitis C virus coinfected. The viral load was negative after two years on lamivudine, entecavir and tenofovir in 86%, 90.6%, and 92.9% of the patients, respectively. The five-year resistance rates for lamivudine, adefovir, entecavir, and tenofovir were 57.5%, 51.8%, 1.9%, and 0%, respectively. The overall seroconversion rates were 31.2% for HBeAg and 9.4% for HBsAg. Hepatocellular carcinoma was diagnosed in 9.7% of patients, liver transplantation was performed in 9.7%, and overall mortality was 10.5%. Elevations of serum alanine aminotransferase (p = 0.0059) and viral load (p < 0.0001) were associated with progression to liver cirrhosis. High viral load was associated with progression to hepatocellular carcinoma (p < 0.0001). Significant risk factors associated with death were elevated alanine aminotransferase (p = 0.0039), liver cirrhosis (p < 0.0001), high viral load (p = 0.007), and hepatocellular carcinoma (p = 0.0008). HBeAg positive status was not associated with worse outcomes, and treatment may have been largely responsible. Conclusions: Elevations of viral load and serum alanine aminotransferase may select patients with worse prognosis, especially progression to cirrhosis and hepatocellular carcinoma, which were strongly association with death.

Metástase cardíaca de carcinoma hepatocelular / Cardiac metastasis in hepatocellular carcinoma

As metástases cardíacas são cerca de 40 vezes mais comuns do que os tumores primários. Metástases de carcinoma hepatocelular ocorrem em estágios avançados da neoplasia, para ossos, pulmões e suprarrenais, sendo raras para o coração. O presente relato apresenta paciente portador de carcinoma hepatocelular, associado à metástase cardíaca, confirmada ao ecocardiograma transesofágico. Ausência de trombo no sistema porta, neste relato de caso, é um achado incomum.
