We report the case of acute hepatitis in a 36-year-old woman that was acquired from an adopted African child with asymptomatic active infection. At present, most experts do not screen for hepatitis A. However, adoptive parents should be vaccinated against hepatitis A because of the risk of unrecognized active infection in adopted children from countries in which infection is endemic.
The molecular mechanisms involved in liver carcinogenesis are poorly understood. Over the past decade, epigenetic changes (DNA methylation) have received increasing attention for their potential involvement in the development of hepatocarcinoma. The DNA methylation level is influenced by environmental factors (folate and methionine diet), as well as by genetic factors (methylenetetrahydrofolate reductase/MTHFR polymorphisms). These findings provide new insight into the understanding of liver carcinogenesis. Interventional studies are now required to determine the role of folate supplementation in the development of liver tumors in targeted patients.
