Résumé
During the past 20 years, several authors have reported increased prevalence of cholelithiasis in liver cirrhosis. This biliary disease has been implicated with the deterioration of liver function, liver disease of alcoholic origin or even the presence of hypersplenism in this patient population. This study analyzes the incidence and possible factors which are responsible for promoting cholelithiasis in cirrhosis. The study included 110 cirrhotic patients of a private center specialized in treating liver diseases. The incidence of cholelithiasis was 27.3 per cent (25.3 per cent in males and 33.3 per cent in females). There was no correlation between liver function defined by Child's classification or through the laboratory examinations (AST, ALT, AP, GGT, PT, Alb, TB, DB, PA) and the presence of gallstones. No evidence was found that the etiology of cirrhosis or the presence/absence of hypersplenism affected the prevalence of cholelithiasis in this population. In conclusion, an increased prevalence of cholelithiasis was verified in this population of cirrhotics but the pathogenesis is still obscure.

Abuso e dependência alcoólica constituem-se nos mais graves problemas de saúde pública, do mundo industrializado. O papel do etanol em provocar doença hepática ou perpetuaçao da lesao dos hepatócitos, encontra-se ainda precariamente definido. Mecanismos patogenéticos essenciais responsáveis pela evoluçao das lesões, sao expostos neste artigo e incluem etanos e metabólitos, fatores nutricionais, genéticos e imunológicos, alteraçoes das membranas biológicas e participação dos virus das hepatites B e C

Manifestaçoes extra-hepáticas das hepatites virais, sao raras e causadas por vírus A,B,C,D,ou E. As mais comumentes observadas sao vasculites sistêmicas, crioglobulinemias essenciais, polimialgias reumáticas, anemia aplástica, glomerulonefrites membranosas e membranoproliferativas, síndrome de Sjogren, encefalite aguda e urticária. Algumas destas sao graves, inclusive com índices elevados de mortalidade. A maioria porém, assume curso clínico leve. Serao comentadas neste artigo
