ABSTRACT

We describe a treatment made with interferon-alpha (IFN-alpha) plus ribavirin of two patients with membranoproliferative glomerulonephritis (MPGN) induced by hepatitis C virus (HCV): Case 1 was a 22-year-old woman with leg and facial edema, hypertension and proteinuria, whose liver biopsy revealed chronic active hepatitis; and Case 2 was a 42-year-old man with anasarca, hypertension and proteinuria, whose liver biopsy indicated cirrhosis. Both had anti-HCV, HCV-RNA and cryoglobulins. IFN-alpha (3 million units (MU), 3 times/week) and ribavirin (1 g/day) were administered for 12 months. The drugs were well tolerated by both patients. Serum alanine aminotransferase (ALT) levels normalized and HCV-RNA became negative. Cryoglobulins disappeared and an improvement in renal disease was seen after 6 months of therapy. However, after 9 months, Case 2 presented ALT elevation, and proteinuria was detected. Two years after the end of therapy, both patients were negative in repeated HCV-RNA and cryoglobulin tests. Case 1 was asymptomatic, with normal liver and renal tests, and Case 2 had normal blood pressure, with mild edema of the ankles. Based on the evolution of these two cases, the association of IFN-alpha and ribavirin may be a therapeutic option for patients with MPGN related to HCV.

ABSTRACT

Após a identificação do vírus da hepatite C (HCV), em 1989, diversos estudos vêm demonstrando a "relação" deste agente viral com desordens imunológicas e manifestações, tidas como extra-hepáticas, tornando-se a mais relevante a crioglobulinemia mista. O presente trabalho visa rever estas manifestações do HCV, analisando os dados publicados, citando exemplos pertinentes e resultados de atividades desenvolvidas no ambulatório de Hepatites da Disciplina de Gastroenterologia da Escola Paulista de Medicina (EPM) - UNIFESP. Serão discutidas amplamente as manifestações bem conhecidas e melhor definidas, tais como a indução de auto-anticorpos (antinúcleo e antimúsculo liso), a crioglubulinemia mista (tipos II e III), o linfoma não-Hodgkin (células B), a glomerulonefrite (membranoproliferativa), a porfiria cutânea tarda e o líquen plano. As manifestações menos freqüentes ou mais polêmicas, tidas ainda com supostas, entre as quais se incluem o diabetes mellitus (tipo 2), a tireoidite (Hashimoto), a sialoadenite a fibrose pulmonar, entre outras, também serão abordadas. Em virtude da grande quantidade de artigos levantados, como conseqüência provavelmente da controvérsia de seus resultados, esta revisão, para fins de publicação, será dividida em duas partes.
